Title: High electron mobility transistor and its manufacture
Inventor: YOSHIDA ICHIRO
IPC: H01L29/778
Filed: 1990-10-05
Abstract: PURPOSE:To effectively accumulate electrons by deep potential in the vicinity of a GaInP/GaAs junction, by a method wherein a specified channel layer is sandwiched by semiconductor layers composed of GaInP. CONSTITUTION:A current channel layer is composed of GaxIn1-xAsyP1-y (0<=x<=0.7, 0<=y<=1), and sandwiched by semiconductor layers composed of GaInP. Firstly an undoped GaInP layer 2 is epitaxially grown on a semiinsulative GaAs semiconductor substrate 1. Secondly As is supplied for a short time, so as to be added to GaInP during the crystal growth of the GaInP layer 2. By repeating this process, e.g. three times, three current channel layers 3, 4, 5 are formed. After the crystal of GaInP is grown, a current supplying layer 6 is formed by doping the GaInP layer with Si ions. Finally a gate electrode 7, a source electrode 8 and a drain electrode 9 are formed on the electron supplying layer 6.

Title: Control device for pneumatic cylinder
Inventor: TANAKA YOSHINOBU
IPC: F15B11/06
Filed: 1993-09-29
Abstract: PURPOSE:To reduce time required for positioning to the next target position by providing solenoid valves supplying and discharging of pneumatic pressure in respect to bilaterial hambers of a pneumatic cylinder divided by a piston and an accelerating solenoid valve which controls supplying and discharging of pneumatic pressure so as to increase pressure difference between the bilateral chambers. CONSTITUTION:A positioning driving signal is input for shifting to the next target position in a control device. Supply and discharge of pneumatic pressure in respect to solenoid valves 6L, 6R are controlled, while the shifting distance which is the difference between the target value and the present value is computed. When the shifting distance is larger than the reference value, the driving signal for an accelerating solenoid valve 7 is output by the control time obtained by the computation, for controlling supplying and discharging of the pneumatic pressure in respect to the accelerating solenoid valve 7. An increasing ratio of pressure difference between bilateral chambers 3L and 3R is increasec by increasing an amount of air to be supplied and discharged in respect to the bilateral chambers 3L and 3R, such that the driving force early reaches the value corresponding to static frictional force. It is thus possible to reduce time required for positioning a slider 2, and improve responsiveness.

Title: Regeneration of zeolite catalyst and regenerating device of catalyst
Inventor: NAGASE YOSHIYUKI
IPC: B01J29/90
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To efficiently regenerate catalytic activity by bringing a zeolite catalyst into contact with a fluid in a supercritical state. SOLUTION: A catalyst with deteriorated activity in a reservoir 1 is sent by a pump P1 to the upper part of an extraction tower 2, while a fluid in a supercritical state is sent by a pump P2 to the lower part of the extraction tower 2 to regenerate the catalyst. For example, supercritical carbon dioxide prepared by heating the fluid temp. to about 80 deg.C by a heater H and pressurizing to about 200 kg/cm2 is used. Then hydrogen peroxide as an oxidizing agent is mixed as an entrainer. The regenerating temp. of the catalyst is controlled to be higher than the supercritical temp. of the fluid so as to give high diffusion property to the supercritical fluid and to efficiently remove org. substances depositing in the pores of the catalyst.  The regenerated catalyst is sent from the lower part of the extraction tower 2 to a slurry separation tower 3 and collected as a regenerated zeolite slurry. Thereby, by increasing the solvent/ catalyst ratio and the treating temp., the residual amt. of carbon is decreased and the catalyst regeneration efficiency can be improved without causing changes in the structure.
