Title: Pulling up device for silicon single crystal
Inventor: MATSUO HIDEYASU
IPC: C30B15/14
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a pulling up device for an Si single crystal, having high heat reserving-insulating effects and capable of reducing heater output and cooling water flow rate, by providing both a cylindrical heat insulating cylinder and heat reserving cylinder on the outer periphery thereof prepared by combin ing many plate members around a heater surrounding a crucible. CONSTITUTION:A polycrystalline Si raw material is filled in a crucible 5 and current is passed through a carbon heater 6 to melt the Si raw material. A seed crystal 14 is then dipped in the resultant Si melt 11 and pulled up to pull up an Si single crystal ingot 15. In this case, since heat reserving.insulating effects of both a heat insulating cylinder 8 and a heat reserving cylinder 9 prepared by combining many plate members (10a)... into a cylindrical shape are high, output of the heater 6 and cooling water flow rate can be reduced. Since the heat insulating cylinder 8 and heat reserving cylinder 9 can be readily purified to provided with purity, characteristics of the Si single crystal are improved. Furthermore, there are advantages in that the cylinders are not readily cracked even on exposure to direct heat of the heater. This becomes an advantageous condition as the diameter is increased.

Title: Device and method for driving ultrasonic wave
Inventor: IIJIMA TAMOTSU
IPC: H02N2/08
Filed: 1990-11-21
Abstract: PURPOSE:To prevent the deformation and breakage of an elastic body caused by pressurization and, at the same time, to stably obtain a high torque by producing longitudinal and flexion vibrations which respectively give a floating and driving forces to the end face of the elastic body and applying an AC voltage having the same frequency as the resonance frequency of the elastic body to the longitudinal vibrations across piezo-electric bodies. CONSTITUTION:When power supply is made for exciting piezo-electric bodies 2a-2d, longitudinal-vibration standing waves occur in an elastic body 1 and then flexion-vibration standing waves are induced. As a result, a floating and driving forces respectively caused by the longitudinal and flexion vibrations are obtained at one end face of the body 1. In other words, the deformation and breakage of the body 1 caused by the pressing force of a moving section 5 can be prevented and a high torque can be obtained stably, since the pressing force is applied in the direction perpendicular to the wide planes 1a and 1b of the body 1. In addition, the elastic body 1 can be easily inverted by alternately applying a voltage across the first and second piezo-electric bodies 2a and 2b.

Title: Apparatus for measuring wire resistance value for main power source unit
Inventor: ERITSUKU SHIYUPUTEITSU
IPC: G01R27/02
Filed: 1990-11-21
Abstract: PURPOSE: To obtain a simple highly reliable instrument by continuously monitoring partial conductivity of a main power source and, when the variation of the linear resistance value of the power source exceeds a preset threshold, indicating a conductivity failure. CONSTITUTION: A processing and signal circuit 32 has a microprocessor (μp) connected to at least one ROM. When a module is connected to a main power source to be monitored, the μP increases the content (i) of a register after an initializing step in which the content '1' of the register is set at '0', reads out values Vc and (Vs)c, and calculates the linear resistance value of the power unit. When the calculated first value is contained in the register, the initial value RLi is stored. In the other case, the μp calculates the difference DRL between the last calculated linear resistance value RL and the first resistance value RLi and compares the difference DRL with a preset threshold s1. When the difference DRL is larger than the threshold s1, the μP sends a failure indicating instruction. When the difference DRL is smaller than the threshold S1, a new measurement cycle is started. Therefore, the module always monitors the linear resistance value and instructs the increase of the linear resistance value to a value larger than the preset threshold S1.

Filed: 1990-11-21
Abstract: PURPOSE: To provide an electronic control device for a stair climbing vehicle such as a wheelchair by determining an inclination of stairs in response to a front and a back ranging sensors, and prohibiting motion on the stairs beyond specified geometric characteristics. CONSTITUTION: In normal conditions, a wheelchair moves along the horizontal ground, constantly checks a sonar (ultrasonic transducer) to dropping in a vertical direction, and checks an inclination gauge 274A. Inclination of a seat part is adjusted by reading the number in the inclination gauge 274A, and holding a user in the vertical direction. As an upward vertical direction inclination of stairs as a sufficient inclination is detected, the wheelchair is transferred to a stair mode, and inclination of stairs, that is of a ramp, is computed based on a traveling distance by encoders 70, 72 and a height of the stair by an ultrasonic sensor 76. When the ramp, or the stair is excessively sharp, further advance is prohibited, and when the ramp or stair is not excessively sharp, the seat part of the wheelchair is adjusted to the lowest stable angle at a top part of the ramp or stair.

Abstract: PROBLEM TO BE SOLVED: To multiply print much information in a small printing area by irradiating the printing area with excitation light of a wavelength inherent to ink, individually detecting emitted light from printing information through an optical filter and reading out the detected light with a reader. SOLUTION: By irradiating the printing area with excitation light from two light sources 3-2a, a light is emitted from the center of ink 3-1 and the light is made to pass through an optical filter 3-4a.
