Title: Production of compound semiconductor
Inventor: TOSHI AKIHITO
IPC: H01S5/00
Filed: 1990-08-29
Abstract: PURPOSE:To obtain AlGaInP crystal having excellent crystal characteristic with all aluminum compositions by forming a AlGaInP system compound semiconductor crystalline film on a substrate under the specific raw material supply and crystal growth condition. CONSTITUTION:A raw material gas-phase mixture of an organic metal compound including group III elements forming a compound semiconductor and hydride of phosphorus is supplied into a lateral reaction tube 1 in the supply rate of 30cm/sec or less and internal pressure of 100Torr or less and a compound semiconductor crystal is grown at a growth temperature of 580 to 630 deg.C. Namely, the surface of a substrate 3 is a little titled and rotated under the reaction condition that the flow rate is low and the growth temperature is low. Thereby, in all aluminum composition, a thin film can be uniformly grown as the crystal on the substrate. Moreover, since the raw material gas is supplied in low concentration into the reaction tube, only a small mount of raw materials is used.

Filed: 1985-10-14
Abstract: PURPOSE:To make it possible to simply and quantitatively inspect the inner surface of a small caliber tube, by inserting a probe equipped with a light emitting fiber and a light receiving fiber in a metal tube. CONSTITUTION:A probe 1 is inserted in a tube T to be gradually moved to the axial direction. With the movement of the probe 1 or in such a state that the probe 1 is stopped at a predetermined position, the light from a light emitter 3 is projected to the inner surface of the tube T from the light emitting end 21 of an inspection part 11 through a light emitting fiber 2. Hereupon, the light receiving ends 41, 51 of two light receiving fibers 4, 5 respectively receive beams of light reflected from the inner surface of the tube T to send the same to photoelectric converters 6, 7. The converters 6, 7 convert the beams of light received by the fibers 4, 5 to electric signals to send the same to a comparator 8. The comparator 8 compares both outputs from the converters 6, 7 to measure the relation thereof and the distance L between the inspection part 11 and the inner surface of the tube. The measured result obtained by the comparator 8 is displayed on a display device 9 and the state such as the reduction of the wall thickness or damage in the tube is inspected.

Title: Testing apparatus for motive power source of hybrid vehicle
Inventor: MIKAMI TSUYOSHI
IPC: B60L50/16
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a testing apparatus by which the operating performance of every motive power source can be tested safely and precisely in a hybrid vehicle which is provided with an engine and an electrically driven motor as motive power sources when the vehicle is running. SOLUTION: At Step SA4, a shift lever is operated to a range N or a range P. Only when the transmission of motive power to a drive wheel from a motive power source is cut off mechanically or the drive wheel is locked so as to be incapable of being turned, the operating performance of an electrically driven motor or an engine is tested at Step SA7 or SA8, it is possible to prevent a vehicle from being moved suddenly, and the safety of the vehicle is enhanced. In addition, according to whether a second operating signal judged at Step SA6 exists or not, an engine test operation and a motor test operation are selected. As a result, the engine and the electrically driven motor can be tested independently, and every motive power source ca be tested precisely.

Title: Test board answering rate display device
Inventor: ISHIBASHI MASAHIRO
IPC: H04M3/60
Filed: 1991-08-16
Abstract: PURPOSE:To improve the consiousness of answerers by setting a target for the rate of answers to an incoming call arriving at the test board of a switchboard. CONSTITUTION:When the incoming call arrives at the test board of the switchboard, a ground signal is outputted from an extension terminal of a wait call display device 1 and when the test board answers, a potential of about 5V is outputted, so when the ground output is sent to an input unit 2, a photocoupler 2a turns ON and the ground signal is inputted to the input terminal of a sequencer 3 through a diode 2b. A program which is inputted to the sequencer 3 previously from an input device 5 sets an answer time to, for example, 11 seconds and the sequencer 3 calculates the number of incoming calls and the number of incoming calls which exceed 11 seconds and outputs them in the form of BCD codes. The outputted BCD codes are inputted to the IC 4a of an external output unit 4 and the number of incoming calls and the answering rate are displayed on LEDs 4b. The answering rate and the number of incoming calls like those can be viewed on a display device in real time at intervals of 24 hours and one hour.

Title: Optical pickup
Inventor: UENO ICHIRO
IPC: H02P29/00
Filed: 1990-08-31
Abstract: PURPOSE:To inexpensively comprise an optical recording and reproducing device by performing the detection and reproduction of a signal with only one optical pickup by providing a filter capable of emitting selectively light on one side out of the light of fundamental wave component and the one converted to a second higher harmonic out of the light from a light source. CONSTITUTION:The fundamental wave component and the second higher harmonic component of a laser beam are emitted by making the light 4 incident on an SHG element 12 via a convergence lens L, and generating the fundamental wave component and the second higher harmonic component of the laser beam by the SHG element 12. Also, the filter 11 is inserted between a collimator lens L and a beam splitter 15 to make a fundamental wave and the second higher harmonic incident on an optical disk D separately. In such a case, the fundamental wave and the second higher harmonic can be used simultaneously by moving the filter 11 on an optical system. Also, it is possible to use only the fundamental wave component or the second higher harmonic. In such a way, the reproduction of a laser disk or CD and that of the optical disk with high density of around four times can be performed only by switching the position of the filter 11.

IPC: B22D11/115
Filed: 1983-12-07
Abstract: PURPOSE:To prevent breakout and bulging with plural water cooled guide plates having cooling liquid passages and to obtain a billet having a solidified structure which is high in an axial ratio with stirring of high efficiency by disposing the plural guide plates so as to enclose the billet under the casting mold of a continuous casting machine in proximity to each other and mounting attachably and detachably a coil to the rear surface thereof. CONSTITUTION:A flow passage 12 for a cooling liquid is provided in each guide plate 11 and cooling water is introduced therein through an upper tube 13 and is discharged from a lower tube 14 to cool the plate 11 itself as well as to accelerate solidification of a billet 1. A coil 21 behind the plate 11 consists of a core 22 and a winding part 23. The integral mounting of the plate 11 and the core 22 of the coil 21 is accomplished by screwing bolts 24a, 24b from a common member 22a to the plate 11. The gap between the plate 11 and the billet 1 is adjusted by interposing a shim 26 via a bolt 25 between the front end face of the core 22 and the rear surface of the guide plate.

Title: Drainage collected pipe
Inventor: NAKAISHI MASAO
IPC: E03C1/122
Filed: 1994-09-26
Abstract: PURPOSE: To secure an effective section area for flowing-down of drain water and provide a revolving force increasing function by furnishing a deflected flow guide in a diametrically enlarged part of a drain water collecting pipe, and forming a deflected flow guide side part only on one side of the diametrically enlarged part. CONSTITUTION: A drain water flow flowing from an upper stage riser pipe 2 down to a drain water collecting pipe 1 is put aside by a deflected flow guide 10 when the flow has reached a diametrically enlarged part 6 of the collecting pipe. The water flows along a deflected flow guide side part 11 formed only on one side of the enlarged part 6 and flows down while swirling on the internal circumferential wall of the part 6. At this time, the direction of flow deflection becomes identical to the direction of swirling flow, so that a large initial revolution force is produced in the drain water, which therefore flows down while revolving along the inside wall of a riser pipe 3. Provision of guide 10 over branch pipe sockets 8, 9 precludes counter-flow into branch pipe.  Because the deflected flow guide side part 11 is formed only on one side of the part 6, the effective section area for flowing-down of the drain water can be secured satisfactorily even though the side part 11 is formed large.
