Title: Semiconductor memory device
Inventor: SUEYOSHI SHIGETAKA
IPC: G06F12/06
Filed: 1983-02-25
Abstract: PURPOSE:To reduce the unnecessary power consumption with a non-selected decoder by controlling X decoder activating signals of two groups of memory cell arrays with the most significant bit of an address Y. CONSTITUTION:Memory cell arrays 1a and 1b as well as 1c and 1d which are divided into four parts to form two groups are selected by X decoders 21 and 22 which work in response to the activating signal sent from an NAND gate, etc. to which the most significant bit of a chip selection signal and an address Y is impressed together with the inverted most significant bit of a chip selection signal and an address Y. Therefore no activating signal is impressed to the decoder 21 or 22 of the non-selection side. Thus the unnecessary power consumption is reduced with a non-selected decoder.

Abstract: PURPOSE:To avoid the warp of a Si substrate and the crack in GaAs films by a method wherein a buffer layer including the low thermal expansion coefficient having the thermal expansion coefficient lower than that of GaAs base thin films as well as lattice matching with the GaAs base thin films is to be grown on the Si substrate. CONSTITUTION:The substrate temperature is adjusted within the range of 550 deg.C-800 deg.C so as to grow an InGaP low thermal expansion coefficient layer 15 having the thermal expansion coefficient at least lower than that of GaAs layers as well as lattice matching with GaAs. Furthermore, a GaAs buffer layer 17 is grown to be thermal cycle annealed in AsH3 atmosphere and then another GaAs buffer layer 19 is grown. Next, InGaP and GaAs are alternately grown as a strain superlattice layer 21 and finally, a GaAs active layer 11 is grown. Through these procedures, when the GaAs base thin films are formed, the InGaP thermal-expansion coefficient layer 15 as a buffer layer can relieve the large difference in the thermal expansion coefficient between the Si substrate 1 and respective GaAs layers thereby enabling the warp of the Si substrate 1 and the crack in the GaAs thin films to be avoided.

Inventor: TAKAHASHI AKIRA
IPC: H04B1/04
Filed: 1986-02-14
Abstract: PURPOSE:To minimize the transmission distortion by making a load impedance at an upper side band and a lower side band of a transmission frequency band equal to each other. CONSTITUTION:A matching device 13 is inserted between an amplitude modulation transmitter 11 and a transmission antenna 12.

Abstract: PURPOSE:To simplify the structure of valve closing device, by arranging the same such that a cam is lightly engaged with the cam shaft of valve moving system in an internal combustion engine and the movement of cam coming into and out of the cam shaft is controlled hydraulically by means of a retaining member provided in the cam shaft. CONSTITUTION:During the absence of output signal to be generated by a controller 14, an oil control valve 13 is in a home position and closes the supply of pressure oil to an oil tube 12. In consequence, a plunger 19 contained in a guide hole 18 defined in the cam shaft 2 to elongate in the direction parallel to its diameter is caused to project outside the cam shaft 2 by the recoiling force of spring 21. A convexed portion 194 is retained in a conical retaining hole 163 defined in the inner periphery of cam 16. Therefore, the cam 16 rotates integrally with the cam shaft 2 to open or close intake and exhaust valves. On the other hand, when the oil control valve 13 is switched to introduce the pressure oil into an oil passage 201 defined in the cam shaft under a light load operation, the plunger 19 retracts inwardly in opposition against the spring 21, causing the cam shaft 2 to rotate idly away from the cam 16 to retain intake and exhaust valves in their fully closed conditions.

Filed: 1980-03-11
Abstract: PURPOSE:To increase the concentration of a program current flowing through an emitter and base junction by reducing the width of a semiconductor region connected to the collector region of a transistor as a programmable cell smaller than that of a base region. CONSTITUTION:When a plurality of row lines and a plurality of column lines intersecting the row lines are drawn on a semiconductor layer, transistors TrTij are formed as programmable cells Mij at the respective intersections thereof.

Title: Voice encoding method
Inventor: NISHIMOTO MASANORI
IPC: G10L19/04
Filed: 1989-02-09
Abstract: PURPOSE:To obtain a synthetic voice waveform being similar to an original voice waveform by adopting a multi-pulse driving type voice encoding method by which a section partitioned by a zero intersection for shifting a low frequency component signal of an input sound signal from a negative level to a positive level or from a positive level to a negative level becomes a frame. CONSTITUTION:A low-pass filter 4 extracts a signal of a low frequency part in a sound signal and sends it out to a fixed level counter 5. The fixed level counter 5 extracts a zero intersection for shifting a level of the low frequency signal from negative to positive or from positive to negative, and sends out section information delimited by the zero intersection to a representative sound source extracting part 11. The representative sound source extracting part 11 takes a correlation by an input sound signal, and spectrum envelope information from a linear prediction analyzer 2, and generates a pulse signal by a position and amplitude calculated by an algorithm of a multi-pulse driving type encoding method at every section determined by section information from the fixed level counter 5. In such a way, a synthetic voice waveform being similar to an original voice waveform is obtained.
