Title: Semiconductor laser element and fabrication thereof
Inventor: TANAKA TOSHIAKI
IPC: H01S5/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor laser in which an optical waveguide is made of nitrogen-based material and which is used in a novel short wave band. SOLUTION: A single crystal substrate 1 is employed and formed in its interior upper zone with a nitrogen diffused layer 2 of an N-type or P-type electric conduction type. The nitrogen diffused layer 2 is formed by surface nitriding so that the interior upper zone of the substrate can be modified to such material that can be easily coupled with nitrogen-based material. An optical waveguide as a crystal layer of nitrogen-based material is formed on the nitrogen diffused layer 2. A one N-side or P-side electrode 9 is formed on the nitrogen diffused layer 2, while the other P-side or N-side electrode 8 is formed on the optical waveguide.  The optical waveguide comprises an passivation layer, an optical waveguide layer 7 for integrally covering an upper surface of the activation layer and a side wall of the activation layer perpendicular to the surface of the substrate, and an optical waveguide layer 5 in contact with a lower surface of the activation layer. The optical waveguide is formed by a single selective crystal growth process. Thereby there can be realized an embedded hetero- waveguide structure which stably guides a fundamental transverse mode due to a refractive index difference between the waveguides.

Title: Endoscope
Inventor: UCHIUMI ATSUSHI
IPC: G02B23/24
Filed: 1990-11-20
Abstract: PURPOSE:To make an endoscope have stiffness for resisting a pushing force, ensure proper torque transmission characteristics at an oscillation section and enable a three- dimensional field of view to be secured by applying the constitution wherein a metal flat braid is externally coupled onto a metal plate dense coil and a resin cover layer is further externally coupled thereto, and inserting an oscillation traction wire of bare state directly in a tubular body at the flat dense coil. CONSTITUTION:The tubular body 7 of the portion of a physical insertion section 2 except an oscillation section 3 is constituted of a metal plate dense coil 12, a metal flat braid 13 covering the aforesaid coil 12 and a resin cover layer 14 concealing the aforesaid braid 13. As a result, slip resistance between the coil 12 and the braid 13 becomes a pertinent value, and torque can be properly transmitted from operation hands to the tubular body 7 of a physical insertion section 2, thereby enabling a field of view of three-dimension to be maintained, aided by the oscillation operation of the oscillation section 3. An oscillation traction wire 5 is kept bare in the second tubular body 7, and in direct slidable contact with the inner side of the plate dense coil 12. A tubular body inner layer, therefore, can resist a compression force generated when the traction wire 5 is strongly pulled by hands.

Title: Press-in and pulling-out method of pile and device therefor
Inventor: YASUOKA KAZUHIKO
IPC: E02D7/20
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To increase press-in and pulling-out capacity without enlarging a hydraulic cylinder and without increasing hydraulic pressure by supplying the discharge oil of a hydraulic pump to a hydraulic cylinder, pressing-in a pile into the ground by the expansion and contraction force of the hydraulic cylinder or improving the pulling technique. SOLUTION: The discharge flow rate of a hydraulic pump is temporarily increased higher than a rating value without changing setting of a pressure regulation valve 9 so as not to increase the discharge pressure of the hydraulic pump. A variable delivery pump 11 is used as the hydraulic pump. However, when the discharge flow rate is increased higher than the rating value, the discharge pressure is lower than the rating value, and excessive load is not executed,. When the discharge flow rate is temporarily increased to be supplied to a hydraulic cylinder 5, press-in and pulling-out capacity of a pile is increased by the inertia effect of the working oil flow of a large flow rate.

Title: Cooling device of internal combustion engine
Inventor: IIDA YUTAKA
IPC: F01P3/22
Filed: 1994-12-20
Abstract: PURPOSE: To conduct suitable cooling control by avoiding insufficient cooling and excessive cooling of cooling water caused by response delay of a motor- driven fan. CONSTITUTION: A motor-driven fan 11 is so arranged as to face a radiator 5. All cooling systems of a water jacket, first and second cooling water passages 6, 7, the radiator 5, a reserve tank 9, etc., are completely sealed. A pressure sensor 17 is so provided as to be communicated with the air phase of the reserve tank 9. An electronic control unit (ECU) controls the motor-driven fan 11 on the basis of the air phase pressure detected by the pressure sensor 17. The change of the air phase pressure responds to the fluctuation of the cooling water temperature. Since pressure in the reserve tank 9 is equivalent to pressure in the cooling water passage, the detected result by the pressure sensor 17 is equivalent to the mean cooling water temperature in the cooling system.  Accordingly, a parameter corresponding to the mean value of the cooling water temperature is detected in real time unlike the conventional technique by which difference is generated in the detected temperature according to the position of a temperature measuring part.

Title: Input conversion circuit
Inventor: KASHIMOTO KOJI
IPC: H03K19/0175
Filed: 1991-12-02
Abstract: PURPOSE:To reduce a delay time in an output signal with respect to an input of the input conversion circuit. CONSTITUTION:A constant current I1 is outputted selectively to a node C or D from a multi-collector transistor(TR) 3 or 4 with a signal inputted to input terminals 1, 2. A current mirror circuit comprising TRs 13, 14 charges/discharges a parasitic capacitance of a TR 16 with an outputted current thereby allowing the TR 16 to be switched, resulting that an output signal is outputted from an output terminal 18. The charge/ discharge of the parasitic capacitance 15 is limited by a voltage clip circuit 12 to clip the amplitude of a gate input potential of the MOS TR 16. The voltage clip range is set by resistors 6, 7. Thus, it is possible to set the clip range of the gate input potential of the TR 16 to be smaller with the resistance of the resistors 6, 7, and a delay time of an output signal with respect to the input is reduced.
