Title: Metal sensor
Inventor: TAKEMOTO TAKATOSHI
IPC: A63F7/02
Filed: 1992-04-17
Abstract: PURPOSE:To speed up the detecting speed of a pachinko ball by comparing calculatively raw data corresponding to the electromagnetic characteristic of a receiving line with reference data to convert the raw data to response data indicating a change in the electromagnetic characteristic for the judgement of a processing unit. CONSTITUTION:A metal sensor carries out the calculative comparison of raw data corresponding to an electromagnetic characteristic of a receiving line with reference data not by a processing unit 30, but by a data converting circuit section 200 provided in a signal transmission system ranging from the receiving line to the processing unit through actions not based on a program. Thus, the calculative comparison carried out in every detecting position in a series of scanning can be speed up and consequently the detecting speed is substantially improved.

Title: Working method of crystal
Inventor: NOJIYOU YASUO
IPC: C30B33/00
Filed: 1982-06-08
Abstract: PURPOSE:To recognize the relation between the cutting position of crystal and the position of a wafer before work by forming the 2nd orientation flat in a different direction from the 1st orientation flat and varying its width continuously in a crystal growth axis direction. CONSTITUTION:The shoulder part 7 and part Tail 8 of LiTaO3 single crystal 6 are cut in an X-axis direction to form a boule 9. A specific flank of this boule 9 is ground by a specific extent (width l3) to form the 1st orientation flat 2. Then, the boule 9 is rotated around its center axis by a specific angle and only the end part of the part Tail 8 is installed at specific height and ground more than the 1st orientation flat 2 to form the 2nd orientation flat 5. Then, the body boule 9 having those flats 2 and 5 is cut to a specific thickness at right angles to an X axis. The widths l1 and l2 of the orientation flat 5 of the wafter are not equal, so the correspondence to the position of the crystal is obtained by its length. Thus, the relation between the cutting position of the crystal and the position of the wafer before the work is known.

In addition, a diagnosis part 5 compares temperatures in respective points at the inside of the stationary apparatus on the basis of, the temperature distribution data from the conversion part 3, and it judges an abnormality when the temperatures in the respective points exceed the temperature reference value.

Abstract: PURPOSE:To miniaturize the heating area as well as the device of a preheater by a method wherein the source of heating steam is switched by a difference between the pressure of heating steam source and a pressure in a steam type air preheater. CONSTITUTION:Steam, entering into a steam type air preheater 2, is switched to an auxiliary steam, fifth extraction steam and fourth extraction steam respectively in accordance with a low, medium and high load.

Title: Turbo type dry vacuum pump
Inventor: SHIMIZU TAKASHI
IPC: F04D29/02
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To reduce assembly mandays by improving balancing of a vortex rotor at the time of high speed rotation. SOLUTION: A vortex stator 25 is formed of stainless steel. Conversely, a vortex rotor 21 is formed of an aluminum alloy composite material of a ceramic content rate of 20%-55% having roughly the same strength as aluminum alloy-steel and having proper workability as well as showing a lower coefficient of thermal expansion than stainless steel. Consequently, stable and high speed rotation is provided without using high degree balancing technology by making mass of the vortex rotor 21 as light as aluminum alloy. Accordingly, it is possible to reduce cost by restraining increase of assembly mandays.

Abstract: PURPOSE:To form an inclined section shaped window controlled to a multilayer thin-film layer by forming the multilayer thin-film layer having a different etching rate to the main surface of a semiconductor substrate and utilizing the difference of etching rates. CONSTITUTION:A plurality of elements A-C are doped to the main surface of a semiconductor substrate 11 to form thin-film layers.

Abstract: PURPOSE:To recover deformation of a fixing roller even when a heat resistant material is formed out of silicone rubber for example by determining compressed set of a heat resistant elastic body impregnated and hardened, as no more than 10%. CONSTITUTION:A fixing roller 1 is formed out of a core metal 2 made of aluminum, an intermediate layer 23 coating round the core metal, and a silicone rubber layer 4 which is a heat resistant elastic body, with which the circumference of the intermediate layer 23 is coated.

Abstract: PURPOSE:To suppress that twist stress is applied to an optical fiber and to prevent the occurrence of the optical axis deviation of the optical fiber by inserting and fixing a flange part of a receptacle between a press plate and a slide plate and adjusting the insertion fixation force. CONSTITUTION:The receptacle 6 arranged in a housing hole 8g in a receptacle holder 8 is set in the state where a pair of flange parts 6b of which are inserted and fixed between the press plate 30 and the slide plate 46, and the insertion fixing force is varied by adjusting a forward/backward variable of a press screw 44 screwed to the step part 8c of the receptacle holder 8 and adjusting sliding gaps among respective members 6, 30, 46. That is, when pressing force to the slide plate 46 by the press screw 44 is adjusted so as to be proper extent, the receptacle 6 is slid in the direction orthogonally intersecting with its axial direction or rotated around its axial center. Thus, the twist stress is hardly applied to the optical fiber 2 and the deviation between the optical axes of the optical fiber 2 and a lens 10 is eliminated.

Title: Method for reducing output distortion of semiconductor laser and semiconductor laser system
Inventor: KADOI MOTOTAKA
IPC: H04B10/564
Filed: 1992-04-20
Abstract: PURPOSE:To achieve a reduction of the distortion of a semiconductor laser by inverting a difference between a detected signal and an input signal and adding the inverted difference to the input signal. CONSTITUTION:A light beam emitted from one side surface of a semiconductor laser 110 is detected by a photodiode 122, and the detected beam is then inverted and amplified by an inverting amplifier 124. This beam is outputted as a detected signal D. An input signal S is outputted after its delay time and level have been adjusted in a delay element 312 in such a way that there is no time difference between an opposite phase component of the detected signal D and the input signal. The input signal S and the detected signal D are added to each other by means of a waveform adder 134, and then distortion components are outputted. The level of the components thus outputted is made constant by an attenuator 136 and a level detecting circuit 138, and the components are added to the input signal S by a waveform adding circuit 139. Therefore, a feedback loop is established so as to cancel the distortion components of a laser beam, so that the distortion components of the laser beam are reduced. The amount of a feedback is controlled by the magnitude of distortion components delivered from an AGC circuit, whereby it is possible to reduce the distortion of a laser beam in a superior manner.

Title: Horizontal deflecting circuit with overcurrent protection circuit
Inventor: TANAKA TOSHIO
IPC: H04N3/16
Filed: 1978-08-16
Abstract: PURPOSE:To simplify miniaturization and IC implementation and also to suppress an anode current by controlling a horizontal driving stage by turning a diode ON (normally OFF) when an overcurrent flows through a gate turn-off switch. CONSTITUTION:When anode current IA of gate turn-off switch GTOQ5 increases due to load L, e.g. a spark in CRT, a voltage (A) across resistance R4 increases and when it becomes above the ON level of diode D1, D1 turns ON. AS a result, the base voltage (B) of transistor TrQ1 varies as shown by the solid line, the ON period of TrQ1, i.e., the OFF period of GTOQ5 expands, and the anode current (C) of GTOQ5 is suppressed as shown by the solid line. Therefore, breakdown of GTOQ5 is prevented.
