Hi,
As I wrote, I am a Vehicle transmission designer on my blog profile page.
I purchased a magazine is "Motor Fan illustrated MT/DCT issue" from Japanese publisher.
It has so many transmission photos, beautiful illustrates and interesting texts.
If you like car or mechanics, it is impressive magazine for you.
So this issue's special is mechanism of "Manual transmission" and "Duel Clutch Transmission".
Notes; typical DCT is VW DSG system, do you know?
In japan, almost passenger car equipped CVT. However, in Europe, they moves from MT to DCT now. Because it is different drive condition between each other countries.
In this magazine, they said DCT is best slution for passenger car....really??
I think which is best depends on aprication, destination, cost and other demands.
Near future, CO2 reduction demands will be increased. Engine displacement should be decrease, Hybrid system will be more used. We have to more deeply consider which transmission solution is best!! So I don't say, somebody did said same.
What function of transmission is most important?
Optimize to engine torque and speed in any vehicle driving condition!!
And torque transmit efficiency!
It is my personal opinion.
Anyway, I am incharge of commercial vehicle transmission development.
Please write in Motor Fan regarding technology of transmission for truck.
Heavy duty truck transmission is The State of the Art I think.
Example,
Formula1 has AMT system, many year ago, HDTruck uses 12speed AMT system. Of course controlled by wire.
And newly system is calculating fuel consumption of engine for gear shift management.
Passenger car world is interesting. Also Heavy duty world is very interesting!
Let's go to book store or web surfing!!!

Hi,
I am planing to next business trip to Europe.
I will visit to Germany, Swiss and Austria (Not fixed yet). It was so cold on last time visit in last December. I hope it will be warm!!
Honestly, I have not enough time because I will visit to four companies in five days....so many move.
If possible, I would like to stay more some days, but I can't approve from my boss....This is business.
Swiss trip,
I went to Swiss over ten years ago. I am grad to visit again.
But I have no time for site seeing!!! haha.
I will be extreme busy......may be.

Hi,
These 2 days, I had meeting with European cooperation company guys for my working. This time meeting is technical discussion. It's was very impressed experience for me. But so tired...I had to use English!!
Thier working style, technical backbone and management are deferent to us. In other hand, same situation for them. But technical documents are common language for each other.
So, our young staff joined meeting. I have to transfer correctly technical interigence and our experience. It is very difficult, but I have to consider how to do this.
I think this issue is "big problem" for all company in the world....
Anyway, off business time, lunchtime and yesterday night dinner.
We invited them to Typical Japanese style restaurant is call "Yakitori house".
They were very relax and talk about many things, we also enjoyed!!
They could eat raw fish "Sashimi" in last night. We did suggest to them for lunch, go to Sushi-shop!!
Today, they went to Sushi-shop, of course moving dish style shop (very cheap!!)
They very enjoyed and said "This style Sushi-shops are in Europe, but fish is not so fresh and not so much kind of fish, it is very good!!"
I relieved...because I had so much kindness from them in Europe then I went.
We promise to them, invite to "Ramen shop" on next time in Tokyo!!
I have to transfer to young guys and other guys my experiense (business issue and night life issue, hahaha)
When next time????
Bye
Hi,
As I wrote this blog, I did buy new wheel for my Kissena bike.
Finally, I changed wheel from carbon wheel and gear ratio.
My new wheel is assembled with kinlin TB-25 rim and red color hub and DT 2.0mm 32 spokes.
This time tire my choise is TUFO S33 special tire.
So, I can adjust spoke and run out of carbon wheel.
I did buy FSA track chan ring for change gear ratio. Current ratio was 48x18(2.67), new is 50x16(3.13). New is 17% faster.
My first impression of checking riding.
Wheel stiffness is enough. TUFO tire is also good. I am not sure about gear ratio is much or not. I will test on tomorrow morning.
Bye,
So cool snowboard!!
Virus snowboards UFC (Ultimate Free Carving) 163.
Will I get this?
Snowboarding day2 at Hakuba Norikura.

Today I did ride very carefully because could not see to detail of surface of snow due to heavy snow and wind.
