Title: Temperature control method for grinding liquid in grinder
Inventor: KOSUGI KEIICHI
IPC: B24B37/015
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent supercooling of grinding liquid by setting the temperature adjuster for the grinding liquid in a tank to an operating state at all times, operating a cooling device of the temperature adjuster when the temperature of the grinding liquid in the tank reaches a prescribed temperature, cooling the grinding liquid, and stopping the operation of the cooling device when the temperature decreases further. SOLUTION: When the temperature of the grinding liquid reaches the set lower limit temperature, a switch 310 is turned on, the grinding liquid W is cooled by a cooling device 304, and the temperature decreases. When the temperature of the grinding liquid W decreases and its temperature after the grinding decreases further, the switch 310 is turned off to stop the operation of the cooling device 304 and then the temperature of the grinding liquid is started to increase, because the heater is turned on at all times and the grinding liquid with a slight heat circulating the grinder is mixed with the grinding liquid in the tank. When the temperature of the grinding liquid increases and reaches the set upper limit, the switch 31 is turned on, the grinding liquid W is cooled by the cooling device 304, and the temperature decreases.

Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To allow selective growth up to a film thickness applicable to a device using a hot wall furnace, related to a silicon or silicon-germanium mixed- crystal epitaxial growth. SOLUTION: When a silicon crystal layer is grown on a silicon exposed surface on a silicon substrate 17 where an insulating film is formed in a reactive chamber 12, such a low-temperature and low water partial-pressure condition as growth temperature is 600 deg.C while a water partial pressure within the reactive chamber 12 is 2×10-8 pa or less, is provided. An epitaxial growth under the condition allows the selective growth of about 120 nm even with no Cl group gas added, while the selective growth of about 280 nm takes place with added Cl group gas thereafter. As a result, even if the reactive chamber 12 is so-called hot wall type, a silicon crystal layer of film thickness about 400 nm is selectively grown on a silicon exposed surface.

IPC: H04N1/00
Filed: 1989-03-30
Abstract: PURPOSE:To reduce the unevenness of transmission by counting a line number (n) in existence in one frame and setting the recording time per line to nearly T/n based on the result of count. CONSTITUTION:When the error correction by one frame is finished at an error correction circuit 7, a line number (n) existing in one frame is obtained. This is obtained by calculating the number of line end signals (EOL) included in an information data (DAT) section. Then recording time T/n in one line is obtained and the T/n is set to a memory 6 properly. Thus, one line recording interval in one frame is nearly constant and no recording time at the end of one frame is not caused. Thus, real time print with less unevenness of transmission is attained.

Abstract: PURPOSE:To reduce the installation space by disposing a valve in the pipe conduit connecting between the pressure source and direct coupling clutch that has first and second switch positions and closes the pipe while switching action is being conducted, thereby switching the valve every time the gear is shifted. CONSTITUTION:Between a pipe conduit 118 connected to the pressure source and a hydraulic cylinder 14 of a direct coupling clutch Cd, a valve 150 is disposed that has first and second switch positions for opening the conduit and temporarily closes the conduit while in transition between the two switch positions. Every time the gear is shifted, the valve 150 is alternately switched between the first and second switch positions. In this manner, even in an automatic transmission having four speeds or more, the lockup can be released at the time of gear shifting by a single valve or adding a few components thereto. Therefore, the installation space can be reduced.
