Title: Semiconductor memory device
Inventor: YAMAMOTO AKIRA
IPC: H01L27/10
Filed: 1984-10-17
Abstract: PURPOSE:To execute low power consumption by installing a word line for plural memory cells each of which stores plural pieces of bit information, and linking this and a block selecting line by the gate circuit controlled by a data line selecting signal. CONSTITUTION:The linking of large word lines W0, W1... of the block selecting line operating in response to an X address decoder output and word lines WD0, WD1... for eight memory cells MC0-MC7 each which stores bit information, etc., is selectively controlled through FETQ3, Q4... operating in response to selecting signals DS0, DS1... of the data line selected by a Y address decoder output. By such constitution, a wasteful electric current will not flow at the memory cell in which the data line is in a non-selective condition, and the low power consumption can be attained.

Title: Power source circuit
Inventor: NISHIZAWA YUJI
IPC: H02J1/00
Filed: 1987-09-01
Abstract: PURPOSE:To establish voltage having predetermined magnitude quickly, by outputting a first voltage when it is rising and a second voltage from a second voltage output means upon rising of the first voltage through a voltage control means. CONSTITUTION:Upon rising of an input voltage V0, base current flows through a transistor 8 to turn it ON, while collector current flows to charge a capacitor 9. When the input voltage V0 increases, output voltage V2 increases with same waveform as that of the input voltage V0. Output voltage V1 also increases with same waveform as that of the input voltage V0. Upon increase of output voltage V3 from AVR4 with at time lag with respect to increase of the input voltage V0, voltage VZD2 lowers below voltage V3 to bias between collector and emitter of a transistor 8 reversely. Consequently, the transistor 8 is turned OFF while a diode 10 is turned ON thus establishing the output voltage V2 having predetermined magnitude.

Title: Emitter coupled logical circuit
Inventor: KUDOU YOUICHI
IPC: H03K19/086
Filed: 1982-12-10
Abstract: PURPOSE:To secure the low impedance of an emitter coupled logical circuit by inserting a switching element which works in response to the switching of an emitter follower in series to the low level side of the emitter follower constituting an output part and therefore connecting the emitter follower to a current sink with conduction in case the output of the emitter follower is set at a low level. CONSTITUTION:The collector output voltage of a transistor TRQ11 which detects the operation of a main current switch is divided by resistances R12 and R13 and applied to the base of a TRQ12 to ensure a follow-up action of the same phase as the main current switch. In other words, the emitter output of a TRQ4 forming an emitter follower is set at a high level when the voltage higher than the reference voltage Vref-1 is supplied to the base of a TRQ1a or a TRQ1b. While the emitter output of a TRQ3 is set at a low level. In such a way, a TR connected to an emitter is turned on when an output of a low level is delivered. As a result, an emitter cut-off phenomenon can be avoided when an output is switched to a low level from a high level.

Title: Variable wavelength dbr semiconductor laser
Inventor: FURUYA AKIRA
IPC: H01S5/34
Filed: 1987-08-31
Abstract: PURPOSE:To obtain a variable wavelength DBR laser with a reduced loss by a method wherein the forbidden band width of a quantum well is controlled by varying the surface passivation conditions and the equivalent wavelength of the forbidden band width is shorter in the wavelength control region of the layer structure of the laser than in the light emitting region and the emitted light wavelength is made to coincide with the wavelength at which the electro- optical coefficient of the wavelength control region has the maximum value. CONSTITUTION:An n-type Al0.4Ga0.6As cladding layer 2, an MQW active layer 3, a p-type Al0.1Ga0.9As waveguide layer 4, a p-type Al0.4Ga0.6As cladding layer 5 and a p-type GaAs contact layer 6 are successively built up on an n<+>type GaAs substrate 1 by MBE to form a layer structure. The layer structure is divided into two regions I and II. An SiO2 layer 11 with a thickness of 2000 Angstrom  is formed on the region II as a passivation film. Then the layer structure is subjected to a heat treatment in a sealed tube under an arsenic pressure of 100Torr and a temperature of 850 deg.C for 40 minutes. As a result, the passivation effect given by the arsenic pressure functions remarkably in the region I to which the arsenic pressure is directly applied and PL of the MQW is maintained at about 820nm. On the other hand, PL of the MQW is shifted to about 805nm by the heat treatment in the region II under the passivation film. In other words, the forbidden band widths E1 and E2 of the regions I and II become 820nm and 805nm in wavelength equivalent respectively.

Abstract: PURPOSE:To make the dimension in the axial direction of a device small by turning a first eccentric ring fitted to the outside periphery of an eccentric part of an eccentric band and a second eccentric ring in its outside periphery, and adjusting a position where a press slide is brought to reciprocating motion. CONSTITUTION:By turning one or both of first and second eccentric rings 3, 4 to a necessary position, a turning-back position where a press slide 6 is brought to reciprocating motion is adjusted. Subsequently, an eccentric shaft 2 is turned, and the motion of an eccentric part of the eccentric shaft 2 is transferred to a slide block 10 through the first and second eccentric rings. The slide block 10 allows the press slide 6 to execute a reciprocating motion continuously through a guide 11, while sliding in the direction orthogonal to the axis of the press slide 6 in a guide 11 by following up turning of the eccentric shaft 2, and brings a stock to forge working by a forming tool 8 which is fixed to the tip of the press slide 6. Accordingly, since the turning-back position at the time of reciprocating the motion of the press slide 6 is adjusted, the dimension in the axial direction of the press slide 6 can be made small.
