Title: Reflection type optical switch
Inventor: WATANABE KAZUAKI
IPC: G02F1/313
Filed: 1989-03-27
Abstract: PURPOSE:To suppress the absorption loss during waveguiding to a low level by forming an optical wave guide layer of a II-VI compd. semiconductor having a large energy gap. CONSTITUTION:The optical wave guide of the reflection type optical switch which is crossed with two pieces of optical wave guides at a certain angle and has an electrode for voltage impression in the crossed part has at least clad layers 12, 14 consisting of the II-VI compd. semiconductor and the optical wave guide layer 13 consisting of the II-VI compd. semiconductor having the refractive index larger than the refractive index of the clad layers on a substrate 11. At least one layer of the respective layers are formed by selective epitaxial growth. Since the wave guide layer 13 is formed of the II-VI compd. semiconductor layer having the large energy gap, the shortening of the wavelength of the guided light is possible. The IV-VI compd. semiconductor has a wide band gap. The absorption loss in the optical wave guide is suppressed to the lower level in this way even if the light (1mum band) of the same wavelength region as heretofore is guided.

Filed: 1985-04-09
Abstract: PURPOSE:To determine easily and automatically base sequence with high accuracy by using one sepn. development row as a reference row and determining the relative position in the reference row based on the inclination of bands with each band on the other sepn. development row. CONSTITUTION:The point where the code for the difference of the level of a signal inverts is determined with one-dimensional waveform 21 and the point 22 where the signal level is max. is found out. A regression straight line 23 is obtd. with one band and an inclination 24 of the straight line 23 in the migration direction is determined, by which the inclination of the band is determined. The 2nd slot is used as a reference lane and one band 31 on the other lane (3rd slot) adjacent thereto is extended along the inclination up to an intermediate point 32 between said lane and the reference lane.

Title: Wire embedded powder molder
IPC: H01G13/00
Filed: 1992-03-31
Abstract: PURPOSE:To prevent a wire from being exposed from an angular and thin powder molding when a wire is embedded in the molding. CONSTITUTION:In a cutting roll component constituted of a roll plate 17 with a lower blade 16 located between an upper punch 1 and a dice 2 arranged on the lower blade 16 and an upper blade 19 counter to the roll plate 17, when the lower blade 16 and the upper blade 19 are engaged horizontally to cut a wire C, the upper blade 19 and the roll plate 17 compress the wire C simultaneously to reduce the width of the wire C. Next, the rolling part of this wire C is embedded in powder A. This process allows rolling of the part of the wire C equivalent to an embedding length; therefore, in the case of molding a molding product having a width about the same as that of the wire C diameter, the embedded wire C is not exposed from the outer wall, so that a high- quality product can be obtained.

Title: Scanning carrier device
Inventor: FURUKAWA KOJI
IPC: H04N1/12
Filed: 1991-04-08
Abstract: PURPOSE:To realize the carrying with high accuracy by providing a dynamic damper acting in the travelling direction in the inside of a carrying track of the scanning carrier device and making a weight of the dynamic damper not in contact with a bottom face of the carrier device to absorb minute unevenness of carrying. CONSTITUTION:A carrier track 12 carried by a screw shaft driven by a drive motor is provided with a dynamic damper 50 comprising a weight 58, dampers 60, 62 and springs 64,66. Moreover, two magnets 70 fixed to the weight 58 and two magnets 72 fixed to a bottom 68 of a case 52 make the weight 58 not in contact with the bottom 68 of the carrying track 12. Since the moment of inertia of the damper 50 due to the fluctuation in the carrying speed is always larger than the friction force by forming the dynamic damper to be a system without friction, the damper 50 is operated in an excellent way thereby absorbing the resonance due to the coincidence between the resonance frequency of the carrier system including the carrying track 12 and the frequency of external vibration such as rotating frequency of the motor and absorbing unevenness of random travelling speed.
Patent JP-H05264700-A (JP)
Title: Driving method for flux gate sensor
IPC: G01C17/30
Filed: 1992-02-14
Abstract: PURPOSE:To reduce the consumed power and realize a stable driving state by selectively outputting a signal component revealed on a detecting coil only at the inversion of exciting current. CONSTITUTION:When the voltage relation between input signals D1, D2 is reversed after a voltage higher than the signal D2 is inputted to the signal D1 to sufficiently saturate an internal core 2 with DC magnetic field, the magnetic field generated in opposite direction separates the core 2 from the saturated state, and a signal is generated in a detecting coil 3. A selection signal G1 continues an analog switch 4 during the time from the inversion to the end of voltage change of the coil 3 and makes only the detected voltage just after inversion outputs X, Y. Since the core 2 is already in the saturated state when an exciting current is inverted, the output signal of a sensor is stably generated just after the inversion even if there is a solid difference in temperature change or inductance. Further, since the signal is selectively outputted imitatively to the inverting time, the output is never influenced even when the excitation is ended without waiting the saturation of the core 2 after the inversion.

Title: Stationary vane type compressor
Inventor: MAEKAWA TAKASHI
IPC: F04C18/356
Filed: 1983-04-28
Abstract: PURPOSE:To prevent burning by providing a coating layer for suppressing inverted rotation against the eccentric shaft section of roller on one sliding face at the sliding section between the roller and eccentric shaft section thereby reducing friction at the sliding section. CONSTITUTION:An eccentric shaft section 9a of a drive shaft 9 and a roller 7 to be fitted over said shaft section 9a are placed in the bore 3 of cylinder 4 while a vane 10 sliding against the outercircumferential face of roller 7 is held by the cylinder 4 to constitute a stationary vane type compressor. In such a compressor, coating layers 15, 16, 17 for suppressing the inverted rotation against the eccentric shaft section 9a of roller 7 are formed on one sliding section between the eccentric shaft section 9a and roller 7. Consequently the speed of inverted rotation of roller 7 can be reduced considerably to reduce the sliding speed between the roller 7 and heads 5, 6 and the top of vane 10 resulting in reduction of friction at the sliding section.

Filed: 1987-03-27
Abstract: PURPOSE:To improve productivity of a sintering machine of an exhaust gas circulation system without degrading cold strength, by controlling a temp.of circulating gas by adjustment of steam pressure in an evaporation part of a waste heat boiler through which an exhaust gas is passed. CONSTITUTION:The exhaust gas is sucked from the sintering machine and after the gas is passed through the waste heat boiler 11, the gas is returned to the sintering machine. The temp. (t) of the circulating gas is measured by a thermometer 30 and a deviation DELTAt between the temp. (t) and optimum temp. t0 is calculated. The stored data on the relation between the temp. of the circulating gas and the steam pressure and the deviation DELTAt are compared and the steam pressure P0 necessary for decreasing the deviation DELTAt to 0 is computed. On the other hand, feed water B is preheated and is sent through a boiler drum 25a to an evaporator 11b. The steam pressure (p) in the drum 25a is measured by a pressure gage 35 and the deviation DELTAp from the pressure p0 is computed. The opening degree of a pressure control valve 34 is so controlled as to decrease the deviation to 0. The temp. of the circulating gas is thereby controlled according to the meltability of sintered ore.
