Title: Semiconductor device
Inventor: MAEDA TAKEO
IPC: H01L29/72
Filed: 1989-02-10
Abstract: PURPOSE:To enhance the resistance to a soft error by a method wherein concentrations of N-wells where a transistor is formed are different from each other. CONSTITUTION:An insulating film 11 is deposited on a P-type silicon semiconductor substrate 10 of a 100 crystal face; the insulating film 11 only in a position used to form a PMOS element is removed selectively by a photoetching method; an opening part 12 is formed. In succession, an N<+>-type buried collector layer 13 is formed by vapor diffusion or solid diffusion of Sb or by ion implantation of As or Sb from the opening part 12. Then, the insulating film 11 is removed from the whole surface; after that, B<+> ions are implanted into the whole surface of o wafer; a first low-concentration buried P-region 9 for punchtrough prevention use is formed. Then, ions are implanted only into a position used to form a memory cell array by using the photoetching method; then, a second high- concentration buried P-region 8 is formed. Thereby, it is possible to obtain a semiconductor device whose resistance to a soft error is high.

IPC: H01L21/208
Filed: 1979-03-16
Abstract: PURPOSE:To lengthen the lifetime of a laser device by a method wherein, on both sides of a semiconductor layer having a light emitting region, No.2 and No.3 semiconductor layers having a larger forbidden band and a smaller refraction coefficient than this are provided and thereby a double-hetero structure is formed. CONSTITUTION:An n-type InP No.1 clad layer 22, In1-XGaXAsYP1-Y active layer 23, a p-type InP No.2 clad layer 24 are laminated and grown on an n-type InP substrate 21. Next, at an interval in the layer 24 and opposit is, an n-type InGaAsP region 25 is formed by selective diffusion. On the layer 24 including this, a Ti-Pt-Au positive electrode 27 is fitted via a p-type InGaAsP ohmic contact layer 26. On the back of the substrate 21 is fitted an Au-Ge-Ni alloy electrode 28, and thereby a light emitting device is constructed. In this way, since the n-type region 25 is buried in the p-type clad layer 24, the concentration of the electromagnetic field on the surface of the resonator and its neighborhood is made slow, and there is no increase in Joule heat due to the concentration of drive current, so that the lifetime is lengthened.

Title: Transverse flow type gas laser device
Inventor: MATSUDA MASAYASU
IPC: H01S3/104
Filed: 1982-03-03
Abstract: PURPOSE:To reduce the consumed power at the time of stopping and to make the discharge rise rapidly at the time of operation by a method wherein a circuit wherein the discharge current can be set variably, and the glow discharge is maintained, and one of circuits fixed to relatively low discharge current is switched by the switch connected to the control terminal of a feedback circuit. CONSTITUTION:A laser light 5 is outputted by discharging by the DC voltage of electrodes 2-3. The difference between the set values of the high potential end 12 of a resistor 11 and an output variable mode circuit 17 is arithmetically operated and amplified 13 resulting in the generation 14 of the pulse which arcs an SCR. When the phase of the pulse varies with the output of the amplifier 13, and accordingly the amplified output 13 becomes high with the discharge current less than the set value, the conduction angle of the SCR is increased and outerwise decreased, and thus the discharge current is always kept constant. When switched to a stand-by circuit 21, the reference volage of the amplifier 13 decreases, then the SCR line is controlled 7 via the feedback circuit 15, and the discharge current decreases in the range wherein the glow discharge does not stop, accordingly the processing is stopped by decreasing the output of the laser light 5, and the consumed power decreases. Since the glow discharge is maintained at the time of restart of operation, a stable discharge is immediately obtained.

Title: Synchronization control system
Inventor: SUKEGAWA FUMIO
IPC: H04L7/00
Filed: 1993-02-23
Abstract: PURPOSE:To prevent the complication of control operations for a synchronous data processor included in a communication network which transmits the data containing the synchronous and asynchronous data. CONSTITUTION:The node devices 2-4 are connected to a transmission line 1 where a synchronous data processor is contained in a synchronous data circuit and the data containing both synchronous and asynchronous data are transmitted. A synchronous data processing part 7 excludes the control data out of a transmission frame by means of an elastic memory to transmit the transmission frame sent from the line 1 to the synchronous data circuit. Then the part 7 converters only the information part of a cell into the formats which are closed forward and continuous. Thus the synchronous data processor can easily specify the positions of cells and channels and can facilitate its control operations. Furthermore a warning signal is produced before the write/read phase difference affects the elastic memory. So that the jitters and the phase difference caused between the node independent synchronous clocks and the network synchronous clocks can be absorbed.
