Title: Epitrochoid type compressor
Inventor: SUGA TSUNEO
IPC: F04C18/10
Filed: 1983-06-01
Abstract: PURPOSE:To reduce clearance volume and improve the efficiency of the compressor by a method wherein the ratio of the eccentricity of a crank shaft for the epitrochoid compressor to the minimum radius of the cylinder curve is specified. CONSTITUTION:The clearance volume ratio is determined by a parameter e/R and a value (n) obtained by adding one (1) to the number of leaves of a rotor. The clearance volume ratio becomes substantially zero when n=3, e/R>0.11 or n=4 6, e/R>0.12 or e/R<0.15 in regardless of the value of (n). It is necessary to provide a clearance between the rotor and a cylinder but the clearance volume may be reduced by keeping the value of e/R within the range of 0.11-0.15 even if the cylinder curve is inflated to the outside of the curve of epitrochoid.

Title: Control circuit of dc motor
Inventor: SHIMODA MASAMICHI
IPC: G11B19/28
Filed: 1992-04-16
Abstract: PURPOSE:To always hold a current value constant even when a phase of a spindle motor is switched and to prevent a power source voltage and a ground voltage from varying by supplying a current corresponding to a difference between a motor control speed and a motor driving current signal to a load circuit. CONSTITUTION:A subtracter 6 obtains a difference between a motor control signal 11 indicating a value of a current to flow to a spindle motor 5 and a motor driving current 12 indicating a value of a current actually flowing to the motor 5, and supplies it to a load circuit 7 as a current corresponding to a subtraction output signal 15 as the signal 15. Thus, at the time of switching the phase, variations in a voltage of a power source 8 and a ground voltage can be prevented.

Title: Charged particle exposure equipment
Inventor: MUNAKATA YASUO
IPC: G03F1/78
Filed: 1985-05-08
Abstract: PURPOSE:To enable continuously correcting the variation of the dimensions of a pattern by providing a sub-deflection control equipment which controls a sub-deflection control equipment which controls a sub-deflection equipment to change the scanning speed of a charged particle beam by a main deflection equipment near the boundary of the non-exposure region and the exposure region of a pictured pattern. CONSTITUTION:The correction of pattern dimensions depends upon a sub- deflection control signal SC generated by a sub-deflection driving equipment 19. The sub-deflection control signal SC has a pulse which has the same timing of the two pulses contained in an edge detection signal ED. The polarity and the gain of the pulse, however, are varied according to the quantity of correction of the dimensions. For example, suppose if the sub-deflection control signal is SC1, i.e., the first pulse is negative and the second pulse is positive, the dimensions are corrected in the longitudinal like a pattern P1. Since the pulse gain can continuously be varied as analog quantity, the quantity of the correction can also be varied continuously.
