Abstract: PURPOSE:To reduce an oscillation threshold current value by removing the active layer and a photowaveguide layer of both sides of a stripe structure selectively etched from the photowaveguide layer having a diffraction grating, an active layer and a protective film on a clad layer by meltback treatment, thereby preventing a leakage current from generating due to a pinhole. CONSTITUTION:A diffraction grating 12 is formed by etching on an n-type InP substrate 11, an n-type InP photowaveguide layer 13, an InGaAs active layer 14, a p-type InP clad layer 15, and a p-type InGaAsP cap layer 16 are sequentially grown nin liquid phase to form a rectangular parallelepiped laminate 17. Then, after a striped etching protective film is formed in (011) direction on the upper surface, the upper surface of the active layer 14 is selectively etched to form a mesa-shaped stripe structure 18. The layers 14, 13 at both sides are removed by a selective meltback with unsaturated InP melting liquid immediately before liquid-phase growing the buried layer. Then, a p-type InP first buried layer 20 and an n-type InP second buried layer 21 are sequentially grown at both sides.

Title: Laser type shift amount measuring apparatus for material tester
Inventor: FURUYAMA TADASHI
IPC: G01B11/00
Filed: 1995-04-26
Abstract: PURPOSE: To detect the amount of a shift between predetermined positions of a body to be tested without marking a sample, by detecting a speckle pattern generated on the surface of the sample by a coherent luminous flux from a laser oscillator by an image sensor. CONSTITUTION: A coherent luminous flux converged from a laser oscillator 27 is cast or a sample 8. As the result, a speckle pattern is generated on the surface of the sample, a part of which is read by a group of CCD elements in an image sensor 28 and stored as an initial pattern signal in a first frame memory within a speckle pattern analysis circuit 31. Then, when a cross head of a tension and compression tester is moved down, the sample 8 is extended and an illumination point of the coherent luminous flux on the sample is moved. The speckle pattern projected into the sensor 28 is also moved. Images in the sensor 28 are sequentially read via a predetermined time interval and read into a second frame memory of the circuit 31. A driving motor is driven to trace a gauge mark of the sample 8 first illuminated by the laser.

Title: Developing device
Inventor: SUZUKI HIROHARU
IPC: G03G15/08
Filed: 1990-04-18
Abstract: PURPOSE:To suppress such a defect as toner scattering while preventing the quality of a visible image from deteriorating by charging electrostatic chargers selectively on the surface of a toner carrier and setting the ratio of the linear speed of a toner carrier and the linear speed of a latent image carrier to a specific value. CONSTITUTION:On the surface of a developing roller 5, the surface of a dielectric 11 and conductive surface 12 are both present having extremely small area, e.g. at a 0.1 - 1.0 mm pitch P of the dielectric. The dielectric 11 of the developing roller 5 is charged electrostatically by friction against a toner supply roller 6 to the negative polarity and then a large potential difference is generated between the respective conductive surfaces 12 and the surface of the dielectric 11 to produce closed electric fields between them, so that much toner having high electrostatic charges are carried on the developing roller 5. Then, the ratio vd/vp is set to 1.2 - 2.5, where vd is the linear speed of the developing roller 5 and vp is the linear speed of a photosensitive body 1. Consequently, while the scattering of the toner and toner filming are suppressed the visible image of high quality which is free from ground staining and has specific density can be obtained.

IPC: G02F1/1343
Filed: 1989-04-21
Abstract: PURPOSE:To lessen crosstalks and luminance inclination with the electrodes of the display device formed of transparent conductive films by disposing auxiliary metallic electrodes which lower the electric resistance of transparent electrodes underneath the transparent conductive films. CONSTITUTION:The auxiliary metallic electrodes 10 are disposed underneath the transparent conductive films 14. Namely, the formation of the auxiliary metallic electrodes 10 by etching is executed with no relation at all with the transparent conductive films 14 and the auxiliary metallic electrodes 10 are formed with good accuracy. The transparent conductive films cover the auxiliary metallic electrodes 10 and the formation of the transparent conductive films 14 is possible without exerting any influence at all on the auxiliary metallic electrodes 10. The good auxiliary metallic electrodes 10 are, therefore, formed and the electric resistance between terminals is lowered. The crosstalks and luminance inclination are lessened in this way when the electrode structure is applied to the display panel.

IPC: F16H48/38
Filed: 1988-04-25
Abstract: PURPOSE:To prevent generation of a shock in a transmission system of both front and rear differential mechanisms or the like by performing switching from a normal speed to a double speed by the switching via a half brake condition by a brake mechanism. CONSTITUTION:In case of a rear part differential mechanism 4 being stopped in its action by a differential lock mechanism 3, one side differential shaft 5 of this rear part differential mechanism 4 is differentially transmitted at a normal speed to right and left front wheels 1 through a front part differential mechanism 2. The rear part differential mechanism 4 is released from its differential action stop by the differential lock mechanism 3, when a differential shaft 6 of the rear part differential mechanism 4 is braked by a brake mechanism 7, because the differential shaft 5, transmitted to the front part differential mechanism 2, obtains a speed almost two times that in case of stopping the differential action, the differential shaft 5 is differentially transmitted at a speed almost double the normal speed to the right and left front wheels 1 through the front part differential mechanism 2.

Filed: 1978-08-24
Abstract: PURPOSE:To shorten extremely the time until a protection circuit is operated by detecting the abnormality of a turn-off power circuit from the increase rate of the rise of negative gate current and then by putting aprotecting power circuit to work. CONSTITUTION:Between the gate and cathode, gate driver unit 22 and protecting power circuit 23 are connected in parallel and to main unit 22, gate turn-off power circuit 26 of electronic switch 24 and direct-current power supply 25 connected in series and gate turn-off power circuit 29 of series-connected direct-current power supply 27 and electronic switch 28 in parallel to circuit 26 are both connected. Once the output of power supply 27 lowers, the increase rate of a negative gate current falls to decrease a voltage across inductance 34 down to less than a reference value, no output is generated by comparator 35 and AND gate 37 becomes open at a lagging point in time, so that the output of inverter 39 will be ''0''. At the same time, both the terminals of capacitor 23 charged higher than the prescribed voltage of power supply 27 are connected between the gate and cathode of GTO3. As a result, GTO3 turns OFF without breaking down by heating.

Title: System for monitoring time slot table
Inventor: YOSHIDA KAORU
IPC: H04J3/14
Filed: 1987-04-28
Abstract: PURPOSE:To prevent occurrence of a case where time slot tables cannot be monitored even when the speed of data communication becomes higher, by using one of the time slot tables for producing signals to be used for multiplexing input data from a channel and the other for monitoring time slots. CONSTITUTION:A switching circuit 4 is controlled by a control circuit 3 and ports 6a and 6b for multiplexing signal are made valid (ON) and ports 7a and 7b for monitoring are made invalid (OFF) against a time slot table 1 which is set for multiplexing the input data of a channel. When no time slot table monitoring request presents, the control circuit 3 writes data in another time slot table 2 for monitoring by controlling a switching circuit 5 and making the ports 6a and 6b for signal valid (ON) at the time when the time slot table 1 outputs data designated by the address of the port 6a to the port 6b in order to multiplexing the input data of the channel. Therefore, the content of the time slot table 1 is copied in the time slot table 2. Accordingly, the time slot tables can be monitored even when the data communication speed becomes faster.
