Title: Magnetic field detector
Inventor: SONODA TOSHIKATSU
IPC: G01R33/02
Filed: 1987-11-11
Abstract: PURPOSE:To enable highly sensitive detection of a very fine magnetic field using a simple and inexpensive detector, by applying a DC deflection magnetic field to a sensor core simultaneously with excitation by an AC current. CONSTITUTION:Primary windings A1 and B1 of sensor cores (a) and (b) of transformers A and B are connected to each other between one-hand input terminals 2 and 6 thereof and an AC power source E and a DC power source D are connected in series or in parallel to other-hand input terminals 1 and 5. Then, an AC current 9 is applied overlapping a DC current 10 to the input terminals 1 and 5 of the primary windings A1 and B1 of the sensor cores (a) and (b) to feed them with a DC deflection magnetic field by the DC current 10 while exciting them by the AC current 9. With such an arrangement, excitation areas of the sensor cores (a) and (b) are deflected to a non-linear areas larger than a non-continuous magnetization area to sense a magnetic field to be detected in a deflected excitation area, optimally, in a rotary magnetization area to measure a magnetic field. This can reduce ceramic noises of the sensor cores as magnetic field detection medium.

Filed: 1985-12-19
Abstract: PURPOSE:The titled fiber that is composed of a polymer mainly containing acrylonitrile of a large intrinsic viscosity and having specific tensile strength and water filtration before fibrilation, thus being used as a substituent for asbestos in the slate production, because it has high resistance to alkali and high strength.

Title: Electronic hemomanometer
Inventor: FUKUYOSHI MASASHI
IPC: A61B5/0225
Filed: 1990-10-24
Abstract: PURPOSE:To eliminate a possibility of causing a congestion of a measuring part otherwise done by an excessive pressure as well as reduction in measuring time by easing a pressure rising speed with the regulation of the driving of a pressure pump when the pressure rising speed is higher than a reference speed value at an initial stage of a cuff & bag pressurization. CONSTITUTION:At an initial stage of a cuff & bag pressurization, a voltage to be applied to a pressure pump 2 is detected and when the detection voltage is lower than a fixed voltage, a pressure rising speed of a pressure cuff & bag 1 is gentle, hence lower than a reference speed value C. Therefore, even if a pressurization is continue at this pressurizing speed, a maximum blood pressure value can be estimated at the initial stage of pressurization with a judgment that a cuff & bag pressurization is detectable. When the detection voltage is determined to be higher than a fixed voltage, a PWM signal of a PWM oscillator 9 is changed so that the cuff & bag pressure rising speed will be about a reference speed value to control the driving of the pressure pump 2. Thus, the cuff & bag pressurization is continued at the cuff & bag pressure rising speed to estimate the maximum blood pressure while the cuff & bag pressurizing point is detected. The pressurization of the pressure cuff & bag 1 is stopped at the cuff & bag pressurization stop point, and an appropriate artery ischemia is done corresponding to a person to be measured.

Title: Vehicle-washing machine
Inventor: NAGASHIMA SUMIO
IPC: B60S3/04
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To adopt an antifreezing measure on a vehicle-washing machine at a low cost. SOLUTION: A vehicle-washing machine A is connected at its water-feed hose 6 with an antifreezing device B. While a high-pressure pump 4 in the vehicle-washing machine A is stopped, the high-pressure air held in a reservoir tank 12 in the antifreezing device B is heated up and fed into the hose 6 on the downstream side of the pump 4 to thus eject the residual water from the hose 6 through an injection nozzle 7. Such ejection of high-pressure air through the nozzle 7, which causes a temperature drop by adiabatic expansion, is made shorter so as not to bring about a freeze. A little amount of heated air is thereafter released through the nozzle 7 continuously to thus prevent a temperature drop by the adiabatic expansion of the air released through the nozzle 7 and to prevent clogging of the nozzle hole by a freeze continuously.
