Title: Semiconductor memory device
Inventor: FUKUMOTO KATSUMI
IPC: G11C11/409
Filed: 1990-05-01
Abstract: PURPOSE:To shorten the delay time of a common data line by biasing the common data line to an intermediate potential by a precharge circuit before a main amplifier starts amplifying a signal appearing from a memory cell onto a data line. CONSTITUTION:A precharge circuit 1 is provided to bias a common data line 7 to the intermediate potential between a power supply potential and a ground potential before a main amplifier 100 starts amplifying the signal.

Title: Voltage controlled oscillation circuit
Inventor: TAKADA SHUICHI
IPC: H03K3/03
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a voltage controlled oscillation circuit which has a circuit structure suitable for an LSI, and has reduced jitter and a wide oscillation frequency range. SOLUTION: Voltage controlled delay circuits(VCD) 22-1 to 22-n are cascade- connected, an output signal of each of the VCDs is selected by selection circuit 23-1 to 23-n, a selected signal is supplied to adder circuit 24-1 to 24-n and a feedback signal is generated. When the VCD on a (k) step is selected, an output of the adder circuit of the (k+1) step is fixed by this selection signal on the (k) step, only the output signal of the VCD on the (k) step is designed to be fed back to the VCD on an initial step successively by way of the adder circuits before the (k) step. Even when an arbitrary number of steps is selected, a reaction loop is always obtained, and the number of reverse circuits to be inserted in the feedback circuit regularly changes in accordance with the number of steps of the VCD.  Thus, it is possible to prevent deviations in an oscillation range that can be varied by a control voltage and in an oscillation range obtained by adjustment of the number of VCD steps, and an oscillation output which continues over a wide range of frequency can be obtained.

Filed: 1982-07-07
Abstract: PURPOSE:To reduce the scale of a program, by transmitting automatically a line synchronizing signal synchronously with a picture data signal when a picture data is transmitted to a printer, etc. CONSTITUTION:When a picture data signal is transmitted to a printer, the data transfer is requested to a CPU with a signal obtained by frequency-dividing 56 a data transmitting timing clock CL signal fed from the printer. The CPU reads out data D0-D7 of prescribed addresses of a display RAM7 and holds the picture data at a holding circuit 54 to apply a parallel-series conversion 55 to the held picture data. When addresses A0-A4 of an address bus 22 are set at L level, the output of an OR circuit 51 is set at H level. A signal SFF is supplied to a parallel-series converting circuit 52 by means of the signal which held 53 the picture data. Thus a series data is obtained. An output line synchronizing signal SY and a data signal DT are set at H and L levels respectively at terminals 81 and 82 and for a prescribed period CL. When the CPU sets the address Ao at H level, the output of the circuit 51 is set at L level. Thus no signal SFF is supplied to the circuit 52, and the signal SY is set at L level. Then the picture data is transferred through the terminal 82.

Title: Control method of engine with supercharger
Inventor: MIZUNO HIROSHI
IPC: F02B37/00
Filed: 1990-05-08
Abstract: PURPOSE:To smoothly perform the change over of one turbocharger operation to two turbocharger operation by making the opening degree of a change over valve means small in the beginning of small control, then gradually increasing the opening degree, and changing over a turbocharger after sufficiently largely opening directly before changing over CONSTITUTION:During small opening degree control, the opening degree of an exhaust change over valve means 17 is made to be gradually large, as a result, the exhaust gas quantity, which is made to flow to a sub-turbocharger is made to increase, and the revolution of a sub-charger 8 is gradually increased. When the opening degree of the exhaust change over valve means 17 reaches sufficiently large set opening degree, although the exhaust change over valve means 17 is fully opened to change over a turbocharger, the sub-turbocharger 8 is, at this time, idling at sufficiently high revolution. For this reason, the reduction of the revolution of a main turbocharger 7 after the full opening of the exhaust change over valve means 17 is suppressed. Therefore, at this time also, the lowering of supercharged pressure is suppressed.

Filed: 1987-05-15
Abstract: PURPOSE:To provide an accommodated object with a space needed for its replacement for improvement on productivity by a method wherein a cover holding the accommodated object is caused to rotate for the opening and closing of the accommodating jig main body opening for the removal or accommodation of the object. CONSTITUTION:A cover 3 helped by a panel spring 10 adheres to an opening 6, keeping wafer arms 8 and 9 and a wafer 7 in an accommodating jig main body 2. When a protrusion of a cover opening shaft engages a groove 15a of a cover opening finger 15 for the rotation of the shaft, the panel spring 10 stretches and looses springiness. The cover 3 rotates and moves from the opening 6 for the establishment of communication between the inside and outside of the main body 2, which is followed by a process wherein the wafer 7 is taken out. Upon arrival of the cover 3 at a position squarely vertical to the surface 2a of the main body 2, the cover 3 is stopped under force exerted by the panel spring 10, which is followed by the replacement of the wafer 7. Following a reverse sequence of steps, the new wafer 7 goes through the opening 6 to be accommodated in the main body 2, the cover 3 is fixed tight by the panel spring 10 to the opening 6, and separation is established between the inside and outside of the main body 2. This design provide an ample space for replacement, which results in an enhanced productivity.

Abstract: PURPOSE:To decrease the generation rate of fine particles of phosphorus pentoxides, and also to exhaust these fine particles quickly so as to prevent pollution of a clean room by equipping a second scavenger, which has a built in cooler for cooling a semiconductor wafer being pulled out from a reaction tube, on the outlet side of a first scavenger. CONSTITUTION:A cooler 14 is provided inside a second scavenger 13 coupled to the opening side of a first scavenger 7, and a mist exhaust duct 15 and a second damper 16 are provided near the opening of the second scavenger 13. By quenching a silicon wafer immediately after this silicon wafer to which phosphor is diffused is pulled out from the reaction tube, the reaction time becomes short, and generation rate of solid phosphorus pentoxides decreases. Moreover, solid phosphorus pentoxides, which are generated partially, are removed to the outside by the second scavenger. Hereby, the contamination of solid or gas arising when pulling out a semiconductor substrate from the reaction tube can be removed, and pollution of a clean room can be prevented.

Title: Isdn exchange
Inventor: HASHIMOTO MASAO
IPC: H04L12/70
Filed: 1989-05-12
Abstract: PURPOSE:To manage definitely a fault of layer 1 or 2 by demultiplexing a call control packet and a data packet from a D-channel packet, converting them into the call control packet and a message of the same form as the signal message of D-channel and supplying them to the ISDN exchange. CONSTITUTION:When a D-channel packet is sent from a terminal equipment of a network termination NTi of i-th ISDN subscriber line 15i, it is received by a termination circuit 16i of the i-th layer 1 and a termination circuit 17i of the i-th layer 2. A packet demultiplex circuit 26 checks a call identifier in the layer 3 of the received data to discriminate the presence of the call control. Since the call identifier is a call packet in the signal processing section 31i, the packet is converted into a D channel message type (SETUP) corresponding to the call packet and converted into a message form represented by the CCITT Q.931. Thus, since the D channel packet is processed similarly to the line exchange call, the fault on a subscriber line or the like is processed at a batch.

Abstract: PURPOSE:To prevent the elimination of the recording information of a magnetic disk by comparing a current signal corresponding to the driving current of an actuator with a reference signal set beforehand and outputting a pulse signal when the current signal is higher than the reference signal. CONSTITUTION:A current detecting means 30 detects a current signal corresponding to the driving current of an actuator 10 outputted by a servo circuit 21, a comparing means 40 compares the current signal with the reference signal set beforehand and when the current signal is higher than the reference signal, a pulse signal is outputted.
