Grace的進修雜記:)

Since we were on campus during the summer term, we decided to make ice moon cake by ourselves.

We dyed those dough before we started to make ice moon cake.

Recently I found out that hands-on experiment requires a lot of patience .

A probe is set to receive a thin film of Aluminum via a thermal evaporation vacuum system. The reason to coat the fiber in the vacuum system is to create a clean surrounding for the coating process. The thermal evaporation vacuum system includes a main chamber, ion gauge, roughing valve, high vacuum valve, fore-line valve, diffusion pump, mechanical pump, flow switch, heat sink, solid state relay, neutral bus, solenoid valves, and ammeter.

It is highly necessary to maintain an interlock for the diffusion pump by using the flow switch and solid state relay. The interlock is needed to prevent damage on the diffusion pump. Specifically, if there is not enough water passing through the flow switch, the diffusion pump cannot be turned on. The diffusion pump needs water when pumping vapor cycle and gas flow inside the system. The diffusion pump, VHS-6, is operated at 120 Volts with the solid state relay controlled by a 24 Volts power supply. Therefore, a solid state relay is designed to switch the power for the load circuitry of the diffusion pump. The neutral bus is technically allowed to bond the wires of the system. This thermal evaporation vacuum system is used to coat a thin layer of Aluminum on an optical fiber. Everywhere except the tip of the optical fiber has been covered in a thin layer of Aluminum.

In this summer during weekdays, most of time I am in the lab, library or my dorm in order to keep everything under control.
When I received the following message from International Student Office, I decided to have fun with them during the weekend.
~~~~Have you ever seen a Bollywood movie?

When we want to have some asian food, we can buy it from Asian market or make it by ourself.
This is the first time for me to make fried dumpling with my friends, and they turn out good.

When the deadly gas-pipeline explosions rock in Taiwan, I sent message to my family and friend.

I just want to make sure nothing going wrong with them, and I got the following message:

Before writing the personal statement, I need to find out who will be my readers. Try to have their attention.
Since I want to get an internship, I decide to start with what I did in the past.

On July 25th, I saw Ghostbusters in Pioneer Square, Portland, Oregon.

The Entertainment began at 7PM, but the movie played at 9pm.

There is an old saying " To see is too believe," and I do agree with that. If I have the chance to prove it by myself, I will remember those theories for long time.
Since I handle the chemical etching in our laboratory, I know how important to neutralize the acid and base. If I need to memorize the reaction function, I will not be able to make it.
After I have some hands-on experiences, I can use Leak Detector to check if there is a leak in my system.

We discover Edelweiss Sausage & Delicatessen by watching The Food Channel.

There are only few seats inside the store, but several customers come to take out their sausages and hams.

I had a presentation, which was scheduled on last Wednesday, but it was postponed to this week.
When I prepared for my presentation, I talked to my roommates, who don't have any background knowledge of my study. The outcome works for me, at least they get the big picture of what i try to explain in the power-point.
Last Friday, when we have group meeting with my professor, who wanted me to change my subject of my presentation.

Hood River is a port on the Columbia River, and it is also a famous place for windsurfing.

When I want to release my stress from studying, Hood River is my best choice. It only takes me around one hour 10 mins by bus, but there are only three buses on the schedule per day.

Most of time I judge people by the first time I meet them, but this is not a good call. Now I learn that don't judge a book by its cover.

因為習慣從第一印象去評價一個人，後來發現有些人剛開始會隱藏自己真實的性格，想把最好的一面呈現給大家，但相處久了就會發現並不是每件事都能如你所願，漸漸的本性就顯露出來。

Due to the miscommunication. I get a free ticker for myself and I can have one guest free admission for the cruise. International Cruise is the event honor our international students who has the achievement of graduating with an degree to PSU.
When I read the following message, it catches my attention.
The Alumni Association and the International Student Life Team are partnering to provide the best send-off event for our graduating international students and their guests. The cost of the ticket includes an entree selection, sides, bread, coffee, tea, soda, raffle prizes, and a 2-hour boat cruise on the scenic Willamette River. Bon Voyage!

Since our laboratory does not have 208 or 240 voltage power for us plug in the diffusion pump, we need to change the heater element to 120 Voltage.
The following message adapts for Varian VHS-6 Full Replacement Heater Assemble 120 V, 2200W. 18.5 A, 6.5 ohms.
The Varian VHS-6 diffusion vacuum pump Stovetop-Style full replacement heater is for use with 120 VAC input power. The heater pulls 2200W, 18.5Amps and has a room temperature resistance of 6.5 Ohms. To change the heater element of the Diffusion pump:
