Title: Manufacture of semiconductor light emitting device
Inventor: MIURA SHUICHI
IPC: H01S5/00
Filed: 1988-12-20
Abstract: PURPOSE:To achieve excellent oscillation even in an adverse using environment by making a mesa part high by etching under the state wherein mask films covering the upper surface and the rear surface are present, and growing current blocking layers so that a p-n junction plane is present in the thickness of a one-conductivity type clad layer in the mesa part. CONSTITUTION:A mask film 6 which covers the side surface of a mesa part that is formed in a stripe shape is formed. Under the state wherein the mask films 5 and 6 covering the upper surface and the side surface of the mesa part are made to remain, a part of a one-conductivity type clad layer 2 and a part of a one-conductivity type semiconductor substrate 1 are further etched, and the mesa part is made high. Then, under the state wherein all the mask films 5 and 6 are made to remain, current blocking layers 7-9 are grown so that a p-n junction plane is present in the thickness of the one-conductivity type clad layer 2 in the mesa part. In this constitution, a current path is not formed at the interface between the mesa part and the current blocking layers. Excellent oscillation can be achieved even in an advance using environment.

Title: Tape cassette for cleaning
Inventor: SASAKI HIDEMI
IPC: G11B5/41
Filed: 1987-12-17
Abstract: PURPOSE:To prevent the misuse of a tape cassette for a cleaning by utilizing the tape end detector of a tape recorder and automatically stopping the traveling of a cleaning tape. CONSTITUTION:When a tape cassette 1 for a cleaning is mounted on the tape recorder, a control circuit 56 judges whether a feeding reel 11A is rotated at a recording and reproducing side or not by an input signal from a sensor 58, and when the reel is rotated in a reverse direction, an LED 62 is light-emitted. When the feeding reel 11A is rotated at the recording and reproducing side, a timer is activated, and the LED 62 is light-emitted when 10sec passes. When a light from the LED 62 is light-received, the tape end detector at a tape recorder side sends a stopping signal to the tape traveling system of the tape recorder, and the traveling of a cleaning tape 12 is stopped. Thus, the rewinding of the tape cassette for the cleaning can be prevented.

Patent JP-H06167519-A (JP)
Title: Dc voltage fluctuation detection circuit
Inventor: HANAWA YASUJIRO
IPC: G01R19/165
Filed: 1992-11-30
Abstract: PURPOSE:To obtain a DC voltage fluctuation detection circuit which enables stable and accurate operation without responding sensitively near a reference voltage of a comparator by connecting a fluctuation checker without setting an integrator before the comparator. CONSTITUTION:When a counter 12 counts the preset number of sampling pulses, an overflow pulse (t) is outputted to be sent to a latch circuit C16 thereafter. Even when an output signal (a) of a latch circuit A13 is applied, the circuit C16 will not start a latching operation before the overflow pulse (t) is applied thereto from the counter 12. Thus, when the over flow pulse (t) is applied from the counter 12, the circuit starts the latching operation immediately and sent out a detection signal 'Z' with a voltage level the same as the output signal (a) of the circuit A13 from an output point Z. As a result, even if the voltage level of an input signal X pulsates as at the bottom, no detection signal 'Z' is sent out unless the duration of the pulsation is long as shown by Y12. Therefore, even if an alarm circuit is connected to the output point Z, the pulsation does not occur intermittently in vain.

Title: Server, client, control method and storage medium
Inventor: SHIMOYAMA TOMOHIKO
IPC: H04N21/4728
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To provide video service, matched with a service request level for each user by storing service request level information from a client and transferring the video data of quality corresponding to the request level. SOLUTION: When a connection request is received from a viewer, a server control part 111 performs registration to a service level management table 119, a band management table 114 and a charging management table 116. Since the service level information is also included in the packet of the connection request, it is stored in the service level management table 119. When a camera server is connected, the respective viewers receive the video service, corresponding to the service level at the time of connection and are charged corresponding to the service level. The higher the service level, the more increased is the number of frames to be transferred per unit time, that is, the transfer interval of video images captured in a capture part 112 is made small, and the video service as moving images which approximates reproduction can be received.

Title: Controller for fountain pump
Inventor: SHIOGAI SHINJI
IPC: B05B17/08
Filed: 1992-11-30
Abstract: PURPOSE:To suppress the degradation of the service life of the relay contacts which turn a pump motor on and off. CONSTITUTION:This controller consists of a water level switch 2 which turns on when the water level in a water tank falls from a prescribed water level, a relay coil 7 which connects the water level switch 2 in series and changes over a normally closed contact 16 and a normally open contact 17 and a pump motor 10 which is connected in series to the normally open contact 17. The series circuit of the water level switch 2 and the relay coil 7 is connected in parallel to the series circuit of the normally closed contact 16 and the pump motor 10. In addition, the connection points of the normally open contact 17, the water level switch 2 and the relay coil 7 are connected and, therefore, the pump motor 10 is not driven even if the water level switch 2 is turned off again after the switch is turned on. The chattering generated by the normally closed contact 16 and the normally open contact 17 is thus prevented and the degradation of the service life of the contacts is suppressed.

IPC: H01L29/73
Filed: 1991-11-08
Abstract: PURPOSE: To further improve a reverse voltage, by constituting a 1st conductivity region having conductivity higher than that of a 1st region at a position other than a planar region on the surface of 1st region. CONSTITUTION: A vertical power MOSFET has a semiconductor substrate having a strongly n-doped wafer 1, to which a weakly n-doped 1st region 2 is adjacent. A strongly p-doped planar region 3 is embedded on the surface of 1st region 2. The 1st region 2 has a region 9, which is the same conductivity type as the 1st region 2 but is strongly doped rather than that, on its surface. This region 9 is extended from an edge 16 of semiconductor substrate to the downside of the gate electrode 6. The region 9 is operated for equalizing field strength on the surface of semiconductor substrate. Thus, the peak of field strength is canceled under a channel stopper 7 and a much higher reverse voltage can be provided.

Abstract: PURPOSE:To facilitate alignment in the direction of light emitting by forming a V-shaped groove having each different specific surface on both slanting surfaces on a specific surface of a silicon substrate, lowering one groove ridge line where a laser chip is fixed, and using the other groove slanting surface as a reflection surface. CONSTITUTION:There is formed a V-shaped groove 11 whose both slanting surfaces are (111) sides on a silicon substrate 10 of (100) sides. The side which is near the inclination 45 deg. to the surface of the substrate 10 is set as a mirror plane 12. A main plane 33 which faces this plane is lowered than a main plane 32 on the opposite side. A laser chip 13 is fixed on the plane 33 in such a manner that a light emitting section is positioned in the lower side. The light emitted from the laser chip 13 is reflected on the mirror 12 and emitted as output light at an optical pass. This construction makes it possible to mount a signal detection photodiode or a laser output detection photodiode on the substrate 10 and hence enhance alignment accuracy.
