Inventor: ASAUMI JUNJI
IPC: C04B35/18
Filed: 1987-06-25
Abstract: PURPOSE: To develop a sintered material having extremely excellent strength, by blending powder Al 2 O 3  and SiO 2  in a specific ratio, further mixing with whiskers, molding, sintering at normal pressure and further subjecting to hot isostatic press treatment.  
     CONSTITUTION: 67W75wt.% calculated as Al 2 O 3  of extremely line Al 2 O 3  or Al(OH) 3  having <0.1μm average particle diameter is sufficiently blended with 25W35wt.% SiO 2  having 0.1μm average particle diameter. The blend is mixed with 5W15wt.% based on the blend of whiskers such as AlN, B 4 C, SiC, TiC, TiN or graphite having ≤200μm length and mixed in wet state to give slurry. The slurry is dried, then press molded and sintered in an inert gas atmosphere such as N 2  or Ar at 1,650W1,750°C. Then the sintered material is subjected to hot isostatic press treatment in vacuum or in an inert gas atmosphere of N 2  or Ar at 1,500W1,800°C under 200W2,500kgf/cm 2  to produce an extremely high-strength Al 2 O 3 -SiO 2 -based sintered material is produced.

Title: Frequency synthesizer
Inventor: OBA MOTOI
IPC: H03L7/187
Filed: 1987-06-24
Abstract: PURPOSE: To short the synchronism pulling-in time at the time of intermittent operations, by respectively providing gate circuits between a reference oscillator and fixed divider and between a voltage-controlled oscillator and variable divider.  
     CONSTITUTION: The input phase of a frequency phase comparator 106 is adjusted to be in-phase in such a way that the input of a fixed divider 109 is stopped by means of a 1st gate circuit 115 when the phase as lags, compared with the output of the fixed divider 109 and the input of a variable divider 104 is stopped by means of a 2nd gate circuit 116 when the phase leads, so as to prevent output of a large phase difference signal. Thus output phases of the fixed and variable dividers 109 and 104 are adjusted to be in-phase by using the 1st and 2nd gate circuits 115 and 116. Therefore, the frequency pulling-in time can be made shorter at the time of intermittent rising and, as a result, the power consumption of radio equipment during its standby state can be reduced sharply.

Title: Road lighting device
Inventor: YAMADA KIYOMICHI
IPC: E01F9/658
Filed: 1991-06-27
Abstract: PURPOSE:To make a lighting angle sharp without dazzling a driver and economically extend the lighting range by detecting the position of a running vehicle, and controlling a shielding means according to the detected vehicle position to shade the illuminating light striking against the vehicle. CONSTITUTION:Each illuminating lamp 10 has an electric bulb 1 nearly in the center, a lighting cover 2 enclosing the bulb 1 on the lower side, and a reflecting plate 3 on the upper side. On one side of the device 10, a plurality of louvers 5 for shading the illuminating light consisting of the direct light from the bulb 1 and the reflected light from the plate 3 are provided. When the lighting angle of the device 10 is sharper than in the past, and the lighting range is wider than heretofore, there is a possibility of the illuminating light striking against the eyes of a driver to cause dazzling when a vehicle comes into the end part of the lighting range. Therefore, the position of the running vehicle is detected, and a part of the louvers 5 situated in the advancing direction of the vehicle is closed by a shading control unit to shade the illuminating light striking against the vehicle, so that the light never strike against the driver. Thus, the number of the devices 10 can be economically reduced more than in the past.

Title: Hydromagnetic actuator
Inventor: YASUKAWA TAKESHI
IPC: H02K44/02
Filed: 1987-06-23
Abstract: PURPOSE: To realize an actuator having simple structure, by utilizing feature of magnetic fluid to be elongated in the direction of magnetic field to be applied thereon.  
     CONSTITUTION: An actuator body 1 is constructed with actuator elements 20a, 20b where magnetic fluid 21a, 21b is sealed in an elastic film member with a slider 6 being held through springs 17a, 17b.

Title: Sensor type control system
Inventor: ABE TERUO
IPC: G01D21/00
Filed: 1986-07-03
Abstract: PURPOSE:To enable the curbing of the corrosion of electrodes of a sensor due to electrolysis by setting an impression voltage on the sensor to be below the decomposition voltage of electrolyte. CONSTITUTION:A circuit of an electronic range shown in the figure, for instance, is so designed that it can correspond to a temperature of about 30-250 deg.C. Now, when the ratio in resistance between a thermistor 6 and a reference resistor 3 at a temperature of 0 deg.C, i.e. RS/R, is set to be 1/4 and E=5V is impressed as a DC supply voltage, a voltage impressed on the opposite ends of the thermistor 6 is VS=1V. Since the resistance of the thermistor lowers at a temperature of 0 deg.C or above, the voltage impressed on the opposite ends of the thermistor 6 does not rise above 1V in this control circuit. Therefore a voltage lower than the decomposition voltage of electrolyte is always impressed on the thermistor 6, and thus the corrosion of electrodes due to electrolysis is curbed. Although the voltage impressed on the electrodes 7 is above 1V at a temperature below 0 deg.C, the water content of the electrolyte is frozen in this case, and therefore the activity of metal ions is suppressed. Thus, the corrosion does not matter practically.

Title: Vapor growth device
Inventor: SUZUKI TATSUYA
IPC: H01L21/31
Filed: 1990-06-15
Abstract: PURPOSE:To supply all substrates equally with a reaction gas, and to improve the uniformity of film thickness among the substrates and resistivity thereof by gradually expanding the diameters of a plurality of reaction-gas discharge holes toward upper and lower both ends from a central section in the vertical longitudinal direction of a nozzle pipe and connecting a reaction-gas introducing pipe at the central section in the vertical longitudinal direction of the nozzle pipe. CONSTITUTION:Since the diameter of the reaction-gas discharge hole 11 of a nozzle pipe 7 is increased gradually toward and end section upper than and an end section lower than a position, where a reaction-gas introducing pipe 12 is mounted, the pressure loss of a reaction gas at both end sections is made remarkably lower than conventional devices, and the flow rate of the reaction gas ejected from all reaction-gas discharge holes can be kept constant. Since the reaction-gas introducing pipe is installed at a central section in the longitudinal direction of the side face of the nozzle pipe, the reaction gas is passed in a reaction vessel at a high temperature and heated sufficiently and introduced into the nozzle pipe, thus equalizing the temperature of the reaction gas ejected from all reaction-gas discharge holes. Accordingly, film thickness among substrate crystals and resistivity can be equalized.

IPC: G01S13/526
Filed: 1988-06-24
Abstract: PURPOSE:To execute an exact phase correction by a simple circuit constitution by providing a phase difference accumulator and executing a phase correction by using this accumulated phase difference. CONSTITUTION:When a reflecting signal vector of each period which has been received now is inputted in order of vectors A-D, phase differences DELTAtheta1-DELTAtheta3 between each vector are detected. Subsequently, the phase differences are accumulated such as only DELTAtheta1 as for the vector B, DELTAtheta1+DELTAtheta2 as for the vector C, and DELTAtheta1+DELTAtheta2+DELTAtheta3 as for the vector D, with respect to the vector A. By controlling the phase of each vector by its accumulated phase difference and returning other vectors to a position of the vector A, its erasion can be executed by any NTI eraser. In this state, a phase difference accumulator accumulates a phase difference signal outputted from an average phase difference detector one after another at every transmitting pulse repeated period, and outputs an accumulated phase difference signal to a sin/cos transducer of the next stage to match a timing of the vectors B-D. Accordingly, the phase correction based on the vector A as a reference is executed to each vector.

Filed: 1988-06-25
Abstract: PURPOSE:To achieve excellent copying by connecting plural transfer rollers to a rotary driving system and providing the system with a transmission system which synchronizes both transfer rollers and sets their mutual, relative rotational speed at almost zero. CONSTITUTION:When a motor 7 is activated, a transmission shaft 8 rotates with the aid of a driving gear 7a and an intermediate gear 8a, and the rotation is transmitted from operational gears 8b and 8c to flat gears 2a and 3a to rotate a transfer drum 1. At this time, transfer rollers 2 and 3 on both sides of the transfer drum 1 are rotated and driven, and ultimately they rotate synchronously. As a result, rotation of the same power is loaded to both sides of a transfer material 4 located inbetween, and therefore it rotates without being twisted. Consequently, fed paper passes transfer stages with the same posture, whereby copying free from color slippage and transfer error is realized.
