Title: Optical beam scanner incorporating light source
Inventor: UEMURA HARUO
IPC: H04N1/113
Filed: 1985-04-16
Abstract: PURPOSE:To make a device small-sized and to make the optical axis adjustment easy by turning or shaking one cylinder body, which incorporates a light source generating an optical beam and an optical system shaping the section of the optical beam, to turn the optical beam and scanning the optical beam thereby. CONSTITUTION:A vertical cylinder body 1 is connected to a motor 2 by a shaft 3 and is turned in the direction of an arrow. A light source 4 like a semiconductor laser is provided in the lower part of the cylinder body 1 and projects the optical beam upward along the axis. The current modulated by a picture signal is supplied through slip rings 5 and 6 and feeding sliders 7 and 8 provided on the outside of the cylinder body 1 to adjust the luminance of the light source 4. The optical beam from the light source 4 is shaped by lenses 9 and 10 to become parallel rays of light and is reflected by a prism 11 stuck to the end part of the cylinder body 1 and is scanned horizontally on the surface of photosensitive materials 13 through an f.theta lens 12. Thus, the adjusting work of the optical axis for assembling is made unnecessary and the device is made small- sized.

Title: Magnetic damper
Inventor: NAKADA SHIGERU
IPC: F04D29/66
Filed: 1993-04-06
Abstract: PURPOSE:To utilize the electromagnetic force generated between a magnetic generating part and a rotating shaft to efficiently suppress the vibration of the rotating shaft by arranging the magnetic generating part on the rotating shaft, arranging a DC electromagnet on the static side opposite thereto, and controlling the DC electromagnet according to the displacement and amplitude of the rotating shaft. CONSTITUTION:The rotating shaft 5 of a compressor 3 is supported by an oil bearing 1. The rotating shaft 5 is provided with a magnetic damper 4. The rotating shaft 5 often generates a large vibration during the operation of the compressor 3. At that time, the vibration of the rotating shaft 5 is detected by a position sensor 7. In a control circuit 8, a signal reversed to the detected signal is carried to an electromagnet 6 on the opposite side. The rotating shaft 5 is attracted thereby to correct the displacement, and the vibration of the rotating shaft 5 is suppressed.

Title: Method and device for controlling speed of induction motor
Inventor: AZUSAZAWA NOBORU
IPC: H02M7/515
Filed: 1993-04-06
Abstract: PURPOSE:To enable suppression of a rush current and an excessive oscillation current at the time of switchover of a doubled controller. CONSTITUTION:At the time of switchover of a controller, first only a power inverter 5 is subjected to a frequency control by an output of a synchronizing frequency command preparing means 41, so that the power inverter 5 by synchronized with an induction motor 6. While a power rectifier 2 is made to operate, thereafter, an output frequency of the power inverter 5 is made to rise by an output of an acceleration frequency command preparing means 42, so as to reaccelerate the induction motor 6. Moreover, a frequency command is corrected by a frequency control means by using a differential value of a terminal voltage of a smoothing capacitor 4 and thereby an excessive oscillation current is reduced. Since the terminal voltage of the smoothing capacitor is lowered by a synchronizing operation, accordingly, a rush current can be suppressed in a large degree. Besides, a negative feedback is applied to the oscillation current by the correction of the frequency by the differential value of the terminal voltage of the smoothing capacitor and thereby attenuation of oscillation is expedited.

Title: Snowmelt freeze prevention structure
Inventor: HORIZOE SHIGEKI
IPC: E01C11/26
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To obtain a low-cost snow melting system requiring no water spray by making a snowmelt freeze prevention structure by using a snowmelt freeze prevention material on which tourmalines as a snowmelt freeze prevention material, are dispersed. SOLUTION: This snowmelt freeze prevention material 1 is obtained by kneading about 62wt.% porcelain clay, about 10wt.% far infrared radiating powder, about 20wt.% carbon powder, about 5wt.% fly ash, about 3wt.% tourmaline, as inorganic matrix materials, and water as a catalyst, forming it into a flat sheet and burning it at about 800 deg.C. The snowmelt freeze prevention material 1 is installed, for instance, on a building roof. The tourmaline here is a cyclosilicate mineral containing boron, and emits radiation most suited to melting snow and ice by absorbing heat around it. Therefore, even if there is a space in a snow cover, as the radiation propagates to individual snow crystals and is absorbed by snow, it exhibits a phenomenal snow melting effect. Thus no water spraying is needed.
