Title: High-pressure-jet spin cleaner
Inventor: AMARI MASAHIKO
IPC: B08B3/02
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a high-pressure-jet spin cleaner capable of excellently cleaning a work in a short time without damaging the work. SOLUTION: A high-pressure cleaning soln. is sprayed on a rotating wafer W from a nozzle 42. Consequently, the cleaning soln. hits against the wafer W more powerfully, and the contaminant is easily released from the wafer W. Besides, the released contaminant is blown off toward the periphery of the wafer W along with the cleaning soln. by the centrifugal force due to the rotation of the wafer W and rapidly removed from the wafer.

Title: Single side-band signal demodulator
Inventor: OKAMOTO MICHIO
IPC: H03D1/24
Filed: 1980-10-20
Abstract: PURPOSE:To pick up carriers with constant amplitude and without phase fluctuation, by adding frequency omega of a residual carrier of a single side-band signal incoming after two multiplications, limiting the amplitude and inputting signals which have frequencies omega1 and omega2 with the relation of 2omega=omega1-omega2. CONSTITUTION:An incoming wave is added to a terminal 11, branched into two  and the result is added 4 via multipliers 1, 2 and after the amplitude is limited 7, they are added to a phase locked loop (consisting of an LPF5, phase detector 8 and voltage controlled oscillator 6). A part of the output (frequency omega2) of the voltage controlled oscillator 6 is applied to the multiplier 1, other part is frequency-divided into omega2(omega1-omega2=2omega) and given to the multiplier 2. When a capacitor Cv is manually adjusted and an amplitude signal detector 9 is adjusted to zero, an output is obtained at the terminal 12 via a rectifying detector 10. With this constitution, the residual carrier of the single sideband signal can be picked up without phase fluctuation at constant amplitude without using a steep BPF.

Abstract: PURPOSE:To raise a processing limit by associating a pressure piston movable in the axial direction of a vessel with a cover member, and providing a pressure member projecting from a processing chamber via the cover member at the end of the piston. CONSTITUTION:A workpiece A is placed on a lower cover 4B through a hearth 20 and a lower mold 21, and charged into a processing chamber 13 from below a high pressure vessel 1.

Then, power is supplied to a heating element 11 to reach the temperature of the chamber 13 to a predetermined temperature. When it reaches an equilibrium state, a pressure piston 12 is switched to a pressurizing direction by the switching valve 43 of a pressure piston driver 40, the piston 12 is moved down by means of hydraulic pressure from a pump 41, and the workpiece A is superplasticized under hot hydraulic pressure by upper and lower molds 19, 21. After a predetermined process is completed, power supply is interrupted, the piston 12 is retreated, and its temperature is lowered to a predetermined value. Then, a lower cover 4B is moved down, and the workpiece A is removed from below. Thus, generation of voids is suppressed to raise its processing limit.

Title: Solar heat collector
Inventor: MATSUMOTO KAZUO
IPC: F24S10/70
Filed: 1981-09-18
Abstract: PURPOSE:To facilitate the control of direction of a mirror by a structure wherein a ratchet pawl and rack type holding back mechanism is interposed between the mirror and a glass vacuum tube in the glass vacuum tube internal mirror focusing type solar heat collector, the internal mirror of which is shifted by means of a magnetic force generated by pivoting a pivoting member along the outer periphery of the glass vacuum tube. CONSTITUTION:The solar heat collector 1 is installed so that the longitudinal direction extends to east and west. When a ring R equipped with permanent  magnets G is pivoted along the outer peripheral surface of the glass vacuum  tube 2, a mounting disc 6 is magnetized and rotated, resulting in rotating a  mirror 8 fitted to the disc 6. With the pivoting movement of the mirror 8, the  ratchet pawl 10 is slided on the circular arc clutch 11 so as to get over the teeth  of the clutch 11 one by one. At this time, because of the engagement between  the ratchet pawl 10 and the clutch 11, the mirror 8 can hold its position without sliding back due to its own weight. Accordingly, the mirror 8 can hold its position even after the ring R is disassembled. Owing to the structure as described above, the control of the direction of the mirror 8 can be performed easily.
