Title: Mirror-finishing method for metallic surface
Inventor: NAGAI MAKOTO
IPC: B24C11/00
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a new mirror-finishing method for a metallic surface for blocking micro-cracks and micro-porosities causing defects on a mirror- finished surface of an alloy steel before polishing to fix crystals falling away easily, followed by polishing. SOLUTION: In a surface-structure high-density treating process, balls are sprayed with compressed air to the deteriorated part of a metallic surface to be processed having micro-defects to form a surface having a high-density surface structure. Then, in a mirror-finishing process, a mirror-finished surface is formed by polishing and smoothing the surface having undergone the surface- structure high-density treatment. Target metals for the surface treatment are SUS, prehardened steel, SKD, high-speed steel, carbide tool steel, and the like. The size of the balls used in the surface-structure high-density treating process are in the range of 20-60 μm, combined with more than one of glass balls, iron balls, crystal balls, and marble balls. The balls are sprayed to an alloy steel surface by being mixed with compressed air of 2 kgt/cm2-6 kgt/cm2.

Title: Impulse demodulating circuit
Inventor: YAMADA KUNIHIRO
IPC: H04B1/707
Filed: 1989-11-27
Abstract: PURPOSE:To demodulate only a target impulse and to enable excellent impulse demodulation with constant pulse width by comparing the detection output of a 1st comparator with a reference voltage which varies automatically with the target impulse. CONSTITUTION:A 1st detector 6 detects a frequency-spread high frequency input Vh(t) to obtain an output Vs(t). In a 2nd detector 7, on the other hand, T2>Tp, where T2 is its discharge time constant and Tp is the pulse interval of an impulse sequence. Consequently, the voltage Vr'' obtained across a capacitor C2 continues to almost hold the peak value of an impulse Vm(t). Therefore, a comparator 9 compares the voltage Vr(t), obtained by attenuating the peak value of the impulse by an attenuator 8 to R2/R2+R3 with the voltage of the detection output Vs(t). Namely, the voltage Vr(t) is represented as an equation I and a threshold voltage Vr(t) corresponding to the level of a target pulse is set automatically. Consequently, an invariably proper waveform state is obtained and only the target impulse having the highest level demodulated and extracted.

Abstract: PURPOSE:To quickly and precisely capture an unusual drop in the number of vibrations and to judge the existence of a corrosive gas at an early stage and free from mistakes by a method wherein the difference in the number of oscillations between the number of detected oscillations of a gas sensor and the number of reference oscillations is detected, an alarm is issued when the difference becomes smaller than a threshold value and the number of next reference oscillations is renewed on the basis of the difference in the number of oscillations. CONSTITUTION:A crystal oscillator-type corrosive-gas sensor 1 whose natural oscillations are dropped when the gas sensor is corroded by a corrosive gas is used. The sensor 1 is oscillated 7, it is sampled 11 at a prescribed cycle, e.g. at a cycle of five seconds, and the difference DELTAF in the number of oscillations between the number of detected oscillations Fn and the number of reference oscillations Fr is detected 12. When the difference in the number of oscillations is lower than a preset threshold value, the existence of the corrosive gas is judged 13, an alarm is issued, and a control action is taken. Then, the difference in the number of oscillations is multiplied by a factor which is smaller than one, e.g. 0.03, it is added to the number of original reference oscillations Fn, the number of reference oscillations is corrected 14, and the number of next reference oscillations is set 15. Thereby, the existence of the corrosive gas can be detected at an early stage and free from mistakes.

Title: Refrigerator
Inventor: YAMAMOTO OSAMU
IPC: F25D21/06
Filed: 1990-11-13
Abstract: PURPOSE:To prevent food from decaying because of a faulty defrosting temperature detection means by providing a control means which raises an alarm with an alarm means if the time of a defrosting timer is shorter than a set time when the defrosting temperature detection means detect a high temperature after power is supplied to a defrosting heater. CONSTITUTION:When an operation timer 15 counts a specified time, a compressor 9 is turned OFF while a defrosting heater 10 is turned ON so as to advance the count of a defrosting timer 19. Then, the temperature of a defrosting temperature detection means is checked for and if the detected temperature is judged to be too high, the defrosting heater 10 is turned OFF so as to proceed with the next step where a count value of the defrosting timer 19 (power feed time of the defrosting heater 10) is read. If the detected value is longer than a preset timer (1 second for example), the operation is turned in cooling operation. When the time is shorter, it will be output to an alarm means 17. Therefore, when the power feed time of the defrosting heater 10 is extremely short, the defrosting temperature detection means 11 can be judged to be faulty, which makes it possible to inform the operator of the operational failure by means of an alarm means, such as a buzzer or an LED.

Title: Switching system to standby line adaptor section
Inventor: FURUYA YOSHIHIRO
IPC: H04M3/22
Filed: 1989-11-29
Abstract: PURPOSE:To accommodate terminal lines to a standby line adaptor section with high reliability without use of a physical switch by connecting the terminal lines to the standby line adaptor section via a selection circuit comprising solid- state logical elements whose outputs are able to be wired-ORed. CONSTITUTION:When a fault takes place in a line adaptor section LC1, a switching request signal RQ1 generated based on the fault acts on a selection circuit SEL via a contention circuit CAC, resulting in connecting a terminal line L1 to a standby line adaptor section ALC via the selection circuit SEL. In this state, even when any of other switching request signals RQ2-RQ16 is generated, it is neglected by the contention circuit CAC and the connection of the terminal line L1 to the standby line adaptor section LAC is kept as it is. This is similar to the case of a fault occurred in any of line adaptor sections LC2-LC16. Thus, a subscriber line or a terminal line is accommodated to the standby line adaptor section with high reliability without need of a physical switch.

IPC: G01H3/00
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide a nondirectional submerged acoustic probe which can catch ultrasonic waves and sound pressures from all directions by providing a piezoelectric detecting element constituted by fixing a granular electrode to the end section of a conductor and coating the electrode with a piezoelectric rubber layer, and then, coating the rubber layer with an electrode layer. SOLUTION: The submerged acoustic probe has a detecting section provided with a piezoelectric detecting element 6 on one end face at the front end of a metallic pipe 1. The pipe 1 is composed of a copper pipe and an insulating pipe 2 having an outside diameter which is nearly equal to the inside diameter of the pipe 1, is inserted into the pipe 1 so that the external surface of the pipe 2 can be tightly adhered to the internal surface of the pipe 1 and the pipe 2 can be protruded slightly from the pipe 1 to secure the electrical insulation between the anode of the element 6 and the pipe 1. A conductor 3 is inserted into the pipe 2 and the element 6 is formed at the front end of the conductor 3.  Since the element 6 has a granular shape, is constructed in a center electrode structure, and is uniformly constituted over the entire peripheral surface of an electrode layer 9, the element 6 becomes nondirectional and can catch ultrasonic waves and sound pressures from all direction. Therefore, accurate under-liquid probing can be realized.

Filed: 1986-12-26
Abstract: PURPOSE:To raise the efficiency of operations by a method in which a tightly closable three-way valve is used for a grout injection control system and an accumulator is also provided. CONSTITUTION:A grout injection control system consists of a storage tank 1, a grout pump 2, a tightly closable three-way valve 13, an accumulator 15, an injection port 12, and a return pipe 7. When a set injection pressure is higher than the sum of heads resulting from pressure loss of the return pipe 7 and also from difference in the levels of the injection port 2 and the tank 1, control is made to set flow rate and pressure by increasing the opening degree of the outlet 13c side of the valve 13 or making the outlet 13b side smaller. The injection under fine pressures and pressure pulsation by the pump 2 are eased by the accumulator 15. The construction cost can thus be cut down.

Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To accurately read the images of the entire original and to miniaturize a device by using a bent fluorescent lamp and irradiating the entire read range of a CCD with the light of almost uniform luminance at a straight tube part. SOLUTION: When the bent fluorescent lamp 6 emits the light, the light is not emitted from tube end parts 6b and 6c to which light shielding tapes 7b and 7c are stuck and the light emitted from the straight tube part 6a (valid illumination range z) illuminates the original 20 provided with the same size as the read range (z) of the CCD 4. In this case, when the tube length of the fluorescent lamp is defined as L, the dimension of the straight tube part 6a is 0.6L and the dimension of the tube end parts 6b and 6c is 0.2L respectively. Thus, the valid illumination range (z) is illuminated by the light of the uniform luminance. The light reflected on the input image line A of the original 20 is passed through a window 5, made incident on a carriage 1 and projected through a reflection mirror 2 and a projection lens 3 on the CCD 4.  The CCD 4 reads the projected image of the input image line A and outputs electric signals to the outside.
