Title: Transistor amplifier
Inventor: TANAKA KUNITSUGU
IPC: H03F1/34
Filed: 1988-09-27
Abstract: PURPOSE:To eliminate the need for a band pass filter or a notch filter by connecting a series resonance circuit comprising an inductance and a capacitor in series connection in parallel with a resistor connected between a collector and a base of a common emitter bipolar transistor(TR). CONSTITUTION:The series resonance circuit comprising the inductor L1 and the capacitor C1 connected in series is connected in parallel with a resistor R1. When the gain frequency band is desired to be split into, for example, the VHF band and the UHF band and the series resonance circuit comprising the inductor L1 and the capacitor C1 is inserted in parallel with the resistor R1 for voltage parallel feedback, since the impedance is low at the resonance frequency of the inductor L1 and the capacitor C1, parallel feedback quantity is amplified and the gain in the middle of the band is limited. On the other hand, the impedance of the series resonance circuit comprising the inductor L1 and the capacitor C1 is increased at low and high frequencies, and only the action of the resistor R1 for voltage parallel feedback is acted. Thus, split gain frequency characteristic curves 12,13 are obtained.

Title: Hot-wire type air flowmeter and preparation thereof
Inventor: TAKAHASHI KEN
IPC: G01F1/68
Filed: 1988-09-30
Abstract: PURPOSE:To prepare the title flowmeter having high response and a simple structure at a high automation rate by providing a heating resistor and an air temp. measuring resistor. CONSTITUTION:A current is supplied to a heating resistor 1 by a power transistor 11 to heat said resistor 1 and control is performed so that the temp. of the heating resistor is always higher by definite temp. than that of an air temp. measuring resistor 6. At this time, only a current weak enough to be capable of neglecting the generation of heat is allowed to flow to the resistor 6 and, by this method, said resistor 6 is used as one for detecting and correcting the temp. of sucked air. When an air stream impinges on the resistor 1, a drive circuit is operated to perform control so as to always make the temp. difference between the resistors 1, 6 constant. This operation is performed by applying feedback so that the voltage obtained by dividing the voltage difference between both terminals of the resistor 1 by resistors 14, 15 becomes equal to the voltage obtained by amplifying the voltage drop of a resistor 13 generated by the current flowing through the resistor 1 by an operational amplifier 9. Therefore, when an air flow rate is changed, the current flowing through the resistor 1 is changed and an air flow rate is measured on the basis of the voltage drop appearing in the resistor 13.

Title: Method and equipment for producing silicon wafer quantitatively contaminated sample
Inventor: TAKANASHI KAZUHITO
IPC: H01L21/66
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To manufacture a contaminated sample which is quantitatively contaminated and has a contaminant element uniformly distributed in plane with a high reproducibility by dropping a fixed quantity of a contaminant solution containing a contaminant and consisting of a volatile organic solvent having a low surface tension on a silicon wafer followed by drying. SOLUTION: A silicon wafer W free from metallic contamination by sufficiently washing the surface is placed on the sample base 3 of a vessel 1. As a contaminant, for example, iron, a fixed quantity of atomic adsorption analyzing Fe 1000 ppm standard solution is diluted with a volatile organic solvent having low surface tension, for example, ethanol having ultrasonic purity to a fixed concentration to prepare a contaminant solution 5. When a fixed quantity of the contaminant solution 5 is dropped onto the center on the silicon wafer W, the contaminant solution 5 is extended substantially to the whole surface of the silicon wafer W to wet the surface.  Thereafter, a lid 2 is put on the vessel, and the organic solvent is evaporated through an air bleeding hole 4 to dry the contaminant solution 5, whereby a silicon wafer sample quantitatively contaminated with Fe uniformly in plane can be manufactured.

Title: Variable speed generator
Inventor: SAWA SHUSUKE
IPC: H02P9/00
Filed: 1989-09-20
Abstract: PURPOSE:To prevent fluctuation of the rotation of a water turbine and a generator by providing a correction power command for matching the electrical output from the generator with the mechanical output from the turbine to be limited upon receipt of a signal indicating operation of a load limiter. CONSTITUTION:A memory 12b is normally outputting the memory content of an input A which is rewritten to the memory content P01 of an input B (P01=P0-P) by the edge trigger s terminal (rising from ON to OFF of 77GL) which is released from load limiting condition. In other words, when the limiting condition is released, external power command P0 is rewritten to the corrected power command P01(=P0- P). Since the external command can be corrected by  P under limited condition and same power command P01 is sustained even upon release from the limited condition, no impact is produced upon release from limited condition resulting in continuous stabilized operation.

Title: Handwriting form-making file for stencil printing
Inventor: UCHIYAMA KOICHI
IPC: B41L13/02
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To effectively and simply make a form for stencil printing for providing a beautiful image quality without necessity of a skill without opening pores even when a hand or finger touches it carelessly. SOLUTION: In the form-making file 1, a fine protrusion and recess surface 5 made of protrusions 5a and recesses 5b is formed on one side surface 2a of a sheet-like base material 2. The each protrusion 5a has a flat surface on its top 5aa, and the each recess 5b is opened in a circular shape. The plurality of the recesses 5b are aligned and disposed. When a stencil base sheet 3 is placed on the surface 2a of the file 1 and drawn by a writing instrument or the like, a synthetic resin film 3b of the sheet 3 is effected by a pressure by writing in a pattern corresponding to the pattern drawn on a porous support 3a, and hence many fine pores are formed. In the case of the form-making, even if a palm of a hand or a finger touches the sheet 3, since the protrusion 5a of the file 1 are flat, there is no fear of opening of a pinhole in the sheet 3 and scumming can be prevented.
