New recruit "Mirai"'s worry of manufacturing Part1
What is necessary to move a cylinder?

Mirai

Nice to meet you. I am Mirai, assigned to design of equipment.
I was asked to design a customer's equipment but I'm new. I'm struggling with it.
That is why I decided to visit Mr. Fuss-free, a master of manufacturing!

Mirai

Mr. Fuss-free! I am designing right now but my customer is having a trouble...
Especially, I head that it is bothersome to pipe and prepare various parts when replacing around valves to move a cylinder.
Any good idea?

Mr. Fuss-free

OK, let's make the situation clear first. There are three items to move a cylinder.
1. Changing the direction of going forward and backward..."valve"
2. Controlling speed..."speed controller"
3. Turning down the volume of exhaust noise..."silencer"

Mirai

That is what I was taught the other day! I understand so far.

Mr. Fuss-free

Your customer is saying, these preparation and piping is bothersome. Am I right?

Mirai

Exactly. But I do not know what to do.... I'm about to panic!

Mr. Fuss-free

Ho ho ho, a smile looks better on you.
Well, I will be introducing the best item for you this time.
Preparation can be done at once, piping is also very easy!

Mirai

That is great. Now, I can recommend the item! Thank you very much!
