Title: Stabilizer device of vehicle
Inventor: KUSAHARA YUJI
IPC: B60G17/015
Filed: 1994-02-21
Abstract: PURPOSE:To reduce the roll of a vehicle body naturally by computing the predicted value of lateral acceleration from the detected signals of driving speed and a steering angle, and control pressure corresponding to the value, converting it into a control signal to the pressure control valve of a hydraulic cylinder, discriminating the operating direction of a directional control valve, and outputting it to the pressure control valve. CONSTITUTION:The predicted value of lateral acceleration from the detected signals of vehicle speed and steering angle, and control pressure corresponding to the predicted value are computed, and a pressure control valve (b) receives a control signal corresponding to the computed value to adjust supply pressure to a hydraulic cylinder (a). A directional control valve (c) switches the flow of supply pressure in the discriminating direction based on the predicted value of lateral acceleration. As a result, the hydraulic cylinder (a) receives supply pressure at a single chamber through the directional control valve (c) from the pressure control valve (b), and operates to the expanding or contracting side while relieving oil pressure from a chamber on the opposite side, so that a moment in the opposite direction to the roll of a vehicle body is generated at a stabilizer bar to reduce the roll angle of the vehicle body actively, so it is possible to return the cylinder to its neutral position timely.

Title: Excimer laser device
Inventor: IDO YUTAKA
IPC: H01S3/041
Filed: 1990-01-31
Abstract: PURPOSE:To make an excimer laser device stable in output by a method wherein laser gas is kept constant in temperature by control. CONSTITUTION:As a large amount of thermal energy is generated in a laser chamber 1 to obtain a laser beam 5, laser gas is cooled by a heat exchanger 6. A partially reflected light 8 taken out of the laser beam 5 is introduced to a photodetector 9 to monitor the intensity of the laser beam 5. When the laser is made to start oscillating, the temperature of an ArF laser gas is set slightly lower than an adequate temperature by controlling the flow rate of cooling water which flows through a heat exchanger through a flow rate control valve 11 to start the laser oscillating. After the laser repeatedly oscillates, when it decreases in output, a control circuit 10 detects it and sends a signal to the flow rate control valve 11 to throttle, whereby the cooling water 12 is made to decrease in flow rate to make the gas inside the laser chamber 1 rise in temperature, and the laser increases in output 5. When the laser recovers its initial output, the cooling water 12 is prevented from decreasing further in flow rate. By this setup, a laser can be kept constant in output without deteriorating in discharge state during the oscillation.

Title: Read-only memory
Inventor: ORIKABE YASUO
IPC: G11C17/00
Filed: 1979-02-28
Abstract: PURPOSE: To realize high-speed operation, to miniaturize a memory and to shorten a manufacture period by storing data by lowering the threshold level of a cell by ion-implantation.  
     CONSTITUTION: Ion-implantation is carried out only as to a cell expected to be stored with, for example, "0". A cell expected to be stored with "1" is not ion- implanted, but left in the same state as transistors Q 12  and Q 22  of a memory peripheral circuit. Then, n-type impurities such as phosphorus are implanted in n- channel FET whose silicon semiconductor substrate SUB is of type (p). Consequently, p-type impurity density of the channel lowers and the threshold level also decreases, realizing the depletion type. For example, the threshold level of the cell without ion-implantation is set to +1V, and that of cell Cej ion-implanted to -4V, thereby storing data in Cej.

Title: Frequency conversion circuit
Inventor: SASAKI ATSUSHI
IPC: H03D7/12
Filed: 1992-02-10
Abstract: PURPOSE:To easily implement MMIC processing by connecting a 1st FET of a mixer section and a 2nd FET of a location oscillation section directly only through a capacitor whose capacitance is small or an inductor whose element value is small. CONSTITUTION:Since a 1st FET (single gate field effect transistor (TR)) 102 of a mixer section and a 2nd FET 103 of a local oscillation section are connected directly through a capacitor whose capacitance is small, MMIC (monolithic microwave integrated circuit) processing is easily implemented. Furthermore, since the capacitor 120 shows a capacitive impedance with respect to the local oscillation signal, the load impedance of the local oscillation section when viewing a drain terminal D1 of the FET 102 from a source terminal S2 of the FET 103 is more capacitive because the capacitor 120 is connected in series, oscillation power is supplied efficiently to the FET 103 of the mixer section and a load in a state close to the optimum load operated stably is given.
