Title: Semiconductor light-emitting device
Inventor: SUGAWARA MITSURU
IPC: H01S5/00
Filed: 1986-02-19
Abstract: PURPOSE:To improve heat dissipation, by providing a semiconductor layer having an opposite type of conductivity to that of a high-resistance buried layer in contact with the surface of a mesa and further providing an electrode formed on the semiconductor layer to be contacted. CONSTITUTION:An N-type InGaAsP active layer 8 and a P-type InP clad layer 9 are grown in that order on an N<+> type InP substrate 7. An insulation film of SiO2 is formed and then etched to provide therein an aperture required for forming grooves in which high-resistance layers are to be buried. Using this insulation film having the aperture as a mask, the structure is etched to form grooves 10 reaching the N<+> type InP substrate 7. After that, N<-> type InP high- resistance layers 10A are buried within the grooves 10 by means of the VPE process. The insulation film of SiO2 used as the mask is removed. A P<+> type InP layer 11 is formed and then an insulation film of SiO2 is further formed. The insulation film is patterned to form a masking film. A P-side electrode 12 and an N-side electrode 13 are formed. A semiconductor light-emitting device produced in this manner can have good heat dissipation when mounted on a heat sink.

Title: High-speed competition control system
Inventor: YAMADA AYUMI
IPC: G06F9/52
Filed: 1989-02-13
Abstract: PURPOSE:To update record at high speed by ending the updating processing of the record by means of successive access for updating, storing a current position, and temporarily completing the successive access. CONSTITUTION:When successive access (ac) B ends the updating processing of a record 3, the current position is stored by a current key, the updating processing of the acB is completed by an ENDREQ function, and a control interval CI is released. Waiting acA positions a record 1 by a POINT function, and after the exclusive control right of the CI is obtained, the acA inputs the record. When the acA completes the updating processing of the record 1, the current position is stored by the current key, the acA updating processing is ended, the CI is released, and the waiting acB updates a record 4. When the acB completes the updating processing of the record 4, the current position is stored by the current key, the updating processing of the successive access acB is ended, the CI is released, and the waiting acA updates a record 2 in the same way. Thus the record can be updated at high speed.

Title: Hydrogen detector
Inventor: FURUMURA SHIROU
IPC: G01N7/10
Filed: 1981-03-09
Abstract: PURPOSE:To enable high-precise detecting of hydrogen, by a method wherein an orifice is mounted between a vacuum pump and a vacuum room, and a vacuum gauge for detecting a pressure is placed between the orifice and the vacuum room. CONSTITUTION:A device is provided with a vacuum room 105 partitioned with a material to be measured and a hydrogen diffusion film, a vacuum pump 107 which exhausts gas in the vacuum room 105 so that the room is brought into a vacuum state an orifice 110 placed between the pump 107 and the vacuum room 105, and a vacuum gauge 108 for detecting a pressure between the orifice 110 and the vacuum room 105. Thus, an exhausting speed at the vacuum pump 107 is decided by a passing amount through the orifice 110. If the exhaust capacity of the vacuum pump 107 changes, a discharge passing through the orifice 110 is kept approximately constant to obtain a constant exhaust speed. This permits the high-precise detection of hydrogen and eliminates the need to perform a frequent correction.

Title: Medium detecting device
Inventor: NITTA KOJI
IPC: B41J11/42
Filed: 1987-02-18
Abstract: PURPOSE:To position a medium different from normal paper like an OHP sheet, etc., with the same accuracy by switching the comparison reference voltage of a reflection type sensor according to the output of a transmission type sensor. CONSTITUTION:Light projected by the LED 2 in the reflection type sensor 4 is reflected by the medium 1 and photodetected by a phototransistor 3. A phototransistor 6 as an independent photodetecting element is arranged on the prolongation of the optical path of the LED 2 across a medium traveling path. When the output of the phototransistor 3 exceeds the comparison reference voltage, the presence of the medium is detected, but this comparison reference voltage is set low when the phototransistor 6 is in the photodetection state and high when not. The reference voltage is therefore high for normal paper which is a diffuse reflecting body and has a large reflection factor and low for the OHP sheet which is a regular reflecting body and has a small reflection factor, so the position of the medium can be detected with the same accuracy in either case.

Title: Numerical control device
Inventor: OTSUKI TOSHIAKI
IPC: G05B19/19
Filed: 1995-02-22
Abstract: PURPOSE: To perform drilling of a hole in an arbitrary depth from a workpiece surface without measuring workpiece shape. CONSTITUTION: In a hole drilling control means 1, when a hole drilling command is input, a tool 3 is made to approach by a quick feed from an upper direction to a position of a hole 4a which must be drilled in a workpiece 4. A position detecting means 2, when the tool 3 approaches the workpiece 4 to arrive at a reference position (point R) R0 determined to a fixed height on a workpiece surface, outputs an arrival signal. The hole drilling control means 1, when received the arrival signal, switches a feed from the quick feed to the cutting feed. With a position of receiving the arrival signal serving as the reference, a moving distance of the cutting feed is commanded. In this way, without premeasuring workpiece shape, drilling a hole of arbitrary depth can be performed.

Title: High velocity atomic beam source
Inventor: NAGAI KAZUTOSHI
IPC: G21K5/04
Filed: 1988-02-18
Abstract: PURPOSE:To make the structure of an atomic beam source compact by applying a high DC discharge voltage between the cylindrical cathode and the rodlike anode, keeping the rodlike anode and the cylindrical ion-stopping electrode at a same potential and providing a magnet so as to generate a magnetic field nearly parallel to the central axis of the cylinder between the cylindrical cathode and the cylindrical ion-stopping electrode. CONSTITUTION:A negative high DC voltage is applied to the cylindrical cathode 21 of an atomic beam source from a DC source 25. The rodlike anode 22 and the ion-stopping electrode 27 is kept at a same potential. The cylindrical cathode 21 is made of pure iron, thus the magnetic field 24 generated by a magnet 23 is applied only in the space between the said cathode 21 and the said electrode 27 in parallel to the central axis of the said cathode 21, and no field is applied in the inner space of the said cathode 21. Therefore residual ions and electrons can be rejected by the electric field and the deflection magnetic field applied between the cylindrical cathode 21 provided with an ejecting hole and the cylindrical ion-stopping electrode 27. Thereby the high voltage DC source for operation of a deflector can be made unnecessary to make the size of the atomic beam source small.

Abstract: PURPOSE:To obtain a good tone quality without deteriorating a picture quality even in case of a high density recording by shifting a frequency of two FM sound carriers by a suitable frequency between adjacent recording tracks. CONSTITUTION:The first and the second sound signals are inputted to the first and the second FM modulating circuits 38, 43, respectively, frequency-modulated in accordance with the sound signal and supplied to a mixing circuit 39. Also, outputs of the circuits 38, 43 are frequency-divided n1, n2 by frequency dividing circuits 40, 44, respectively, and thereafter, supplied to phase comparing circuits 41, 45. In this state, when an FM sound signal is superposed on a video track, and recorded and reproduced, a lot of components, especially, corresponding to an odd order, among undesired waves are detected from video heads 9, 10 at the time of reproduction. In this case, at least only one of the FM sound carriers is varied in accordance with a head control signal 33 so that the undesired wave becomes a frequency of the minimum energy. That is to say, it is varied by odd times of 1/2 fH (fH is a frequency of a horizontal synchronizing signal). Concretely speaking, a good picture quality is obtained by selecting suitably a frequency dividing number of fH frequency dividing circuits 51, 52 and the circuits 40, 44 in accordance with the signal 33.
