Title: Arrestor
Inventor: ISHIZAKI YOSHIHIRO
IPC: H01C7/12
Filed: 1987-09-17
Abstract: PURPOSE:To prevent arc discharge into a cubicle and thus to minimize the damage when one phase of an arrestor is shortcircuited by mounting a shortcircuiter metal on a spacer so that the shortcircuiter metal can drop when the temperature increases. CONSTITUTION:When a zinc oxide element 2 is deteriorated and a leak current to the zinc oxide element 2 increases, which, as a consequence, increases the temperature of the zinc oxide element 2, a low melting point solder located at the mounting section of an upper metal spacer 14 and a weight 16 is melted, and the weight 16 drops along the side of the zinc oxide element 2 of its own weight until it gets rested on a lower metal spacer 18. At this point, because the weight 16 is electrically connected to the upper metal spacer 14 through a shortcircuiter lead wire 15, the upper metal spacer 14 and the lower metal spacer 18 are shortcircuited through the shortcircuiter lead wire 15 and the weight 16. As a result, the current passing through the zinc oxide element 2 is bypassed, thereby preventing the zinc oxide element 2 from undergoing an arcing ground. There is no arcing inside the arrestor especially in a non- grounded system.

Title: Liquid level measuring device
Inventor: NISHIGUCHI OSAMU
IPC: G01F23/28
Filed: 1990-08-31
Abstract: PURPOSE:To sense accurate liquid level at all time by furnishing at the liquid level a reflex board elevating and sinking plumbly, receiving a light receipt signal, adjusting the light emission angle of a light projection part in accordance with the light incident condition on a light receiving part, and thereby measuring the light emission angle at the light projection part. CONSTITUTION:In the steady state, the light emitted by a light projection part 3 is reflected by a reflex board 2 and cast onto a light receiving part 4 in its position between light receiving elements (a, b). Therein a motor driving circuit 6 remains with no signal feeding, and no rotate command is given to a motor 7. Thus a potentiometer 8 is at a standstill, and the current light level is indicated. If the liquid level sinks, for example, while the light emission angle of the light projection part 3 remains unmoved, the reflex board 2 displaces down, and the reflected light in put incident to the lefthand element (a). Therein a leftwise rotate signal is given to the motor 7 from the driving circuit 6, and the light projection part 3 turns counterclockwise, and the motor 7 stops when the reflected light is incident between the elements (a, b). At this time, a meter 8 will show the liquid level in sunk position. Accordingly, accurate liquid level is obtainable only by measuring the light emission angle at the time.

Title: Idler holding mechanism at neutral position for magnetic recording and reproducing device
Inventor: YAMASHITA YOSHIHARU
IPC: G11B15/665
Filed: 1989-09-08
Abstract: PURPOSE:To reduce energy consumption by holding an idler at a neutral position, where the idler is not engaged with a reel stand, by the attraction force of a permanent magnet. CONSTITUTION:In order to pull out a magnetic tape 15 from the inside of a cassette by a tape loading mechanism, a driving wheel 7 is rotated by a motor 5 in advance and a swing plate 10, which is directly or indirectly engaged frictionally with the driving wheel 7, is turned. By this turn, an engage part 18 of the swing plate 10 arrives at a position, where the swing plate 10 is abutted with a block member 17 in a block position. Afterwards, even when the rotation of the motor 5 is stopped, the engage part 18 of the swing plate 10 is attracted and coupled with the lock member 17 by the magnetic force since, for example, the abutting surface of the block member 17 is formed to be a permanent magnet 22 and the engage part 18 is composed of a magnetic substance. This magnetic force is set in a size so that the coupling of the both can not be detached even to external disturbance, and even when the disturbance is generated, the idler holds the neutral position without fail. Thus, in order to hold the idler at the neutral position, it is not necessary to continuously rotate the motor and the energy consumption can be reduced.

Title: Automatic focusing adjustment method of video tape recorder with camera
Inventor: HAN BIYUN WAN
IPC: G02B7/28
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To minimize the change of a focus evaluation value to realize stable focusing by calculating a focus evaluation value calculation area corresponding to a zoom magnification to be set and automatically adjusting the focus based on the focus evaluation value obtained by adding a high frequency signal to it. SOLUTION: When a zoom magnification of a lens 10 is set, a CPU 70 takes a signal as the input to send a signal S of a focus evaluation value calculation area A to a lens control data processing part 60. The processing part 60 takes the signal S, horizontal and vertical synchronizing signals, and a clock signal as the input to calculate the area corresponding to the zoom magnification and adds the high frequency signal to the area A to output the focus evaluation value. Based on this focus evaluation value, the CPU 70 outputs automatic exposure and zoom magnification control signals to automatically control a stop driving part 80 and focus and zoom motor driving parts 90 and 100. Thus, the change of the focus evaluation value is minimized, and stable focusing is automatically executed.

Title: Radio zone constitution system in mobile communication
Inventor: SAKAMOTO MASAYUKI
IPC: H04B7/26
Filed: 1985-10-18
Abstract: PURPOSE:To improve the repetition of a frequency in terms of place without reducing a desired wave versus disturbing wave ratio (D/U) by using plural directivity antennas having a sectorial directivity as the antenna of a base station and using the same frequency by so-called reverse antennas having less interference quantity of the antenna. CONSTITUTION:At sectors 7, 10 the same frequency group F1, is used, at sectors 8, 11, the group F3 and at sectors 9, 6, the group F2. At the time of using the frequency repetitively, in the sector 7, for example, a radio wave from an antenna 23 at the sector 10 at the opposite side and using the same frequency becomes an interference wave. However, a radio wave irradiated from the antenna 23 of the sector 10 toward the sector 7 has a level lower by the front back ratio of the antenna (the ratio of the front and back radiation level in a directivity antenna, that is, F/B in interference level). In the antenna manufactured by a conventional method, it is easy to ensure the F/B by 25dB or above.

Title: Laser output controller
Inventor: MIZOGUCHI KAZU
IPC: H01S3/134
Filed: 1986-10-02
Abstract: PURPOSE:To improve the instability of laser output control, by altering the reflecting surface of a hollow reflecting waveguide for attenuating laser light from a conventional mirror reflecting surface to a scatter reflecting surface to cancel the variation of the attenuation rate based on fluctuation of a polarizing direction. CONSTITUTION:Since an incident laser light has no directivity as seen in a macro manner on a random reflecting surface for reflecting at random the light by irradiating it perpendicularly to a random reflector 8 which is uniformly roughened, the average value of the reflectivity becomes constant as a whole even if a polarizing direction is varied. The light which is reflected perpendicularly and returned to the laser side is attenuated by random reflection, and the influence to the laser oscillation can be ignored. The light produced from a hole 17 opened at a part of the wall of the waveguide is detected by a high speed optical detector 9, converted to an electric signal, compared with the output command signal 10 of the laser light, and its error signal is amplified by an amplifier 11 to control the power value of a power source 5, thereby controlling the pump intensity of a laser medium to stabilize the intensity of the laser light.

Filed: 1988-09-20
Abstract: PURPOSE:To obtain a large magnification factor without degrading the oscilla tion characteristics by a method wherein an output mirror to which a partial reflective coating is applied is provided at a laser beam exit after a reflective mirror. CONSTITUTION:Among lights scattered from a convex mirror 3, lights leaked at the position of the convex mirror 3 are bent by 90 degrees by a 45 deg. coupling mirror 5 and some of them are reflected in accordance with the reflectance of the partial reflective coating 2 of an output mirror 1 and the other lights are transmitted and taken out as an output beam. If the hole diameter of the 45 deg. coupling mirror 5 is denoted by 2b and the beam diameter on a concave mirror 4 is denoted by 2a, the magnification factor of a resonator is expressed by a formula of M=a/b. If the reflectance of the output mirror is denoted by R, the total coupling factor TOof the resonator is expressed by a formula of TO=(1-1/M<2>)(1-R). If the reflectance R of the output mirror 1 is 0.6 (60%), the coupling factor TO=0.3 and (IO/IS.A)/(IO/IS.A)max=0.96. Therefore, the oscilla tion capability of the resonator can be fully exhibited.
