Title: Switching power supply and method for operating the same
Inventor: SAITOU MASAYOSHI
IPC: H02M3/28
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply capable of reducing power loss in a queuing mode. SOLUTION: A switching power supply feeds pulsating currents, obtained by rectifying commercial AC power, to a transformer intermittently by a transistor. It rectifies and smoothes the output of the transformer to generate a first DC output voltage V1, and also has a regulator that generates a second DC output voltage V2 which is more stable than the first DC output voltage V1. In the energy-saving mode that is achieved when a control signal SLP is H level, a second voltage detecting circuit is operating and repeatedly sends operation or non-operation signals to a PWM circuit, in such a way that the first DC output voltage V1 changes between threshold Vth1 and Vth2 to cause the transistor and PWM circuit to operate intermittently. A second DC output voltage V2 outputs a stable voltage, irrespective of the modes.

Title: Switching power supply and method for operating the same
Inventor: SAITOU MASAYOSHI
IPC: H02M3/28
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply, capable of maintaining the high efficiency of power conversion at low-power consumption time such as queuing state of an apparatus. SOLUTION: In this switching power supply, because a mode changeover terminal 100 becomes H level in a queuing mode, a light-emitting part 102a of a photocoupler 102 will not light up and a light-receiving part 10 becomes non-conducting. Thus, a base current is supplied to a switching transistor 6 via only a resistor 7. While in the normal mode, because the mode changeover terminal 100 becomes L level, the light-emitting part 102a of the photocoupler 102 lights up. As a result, the light-receiving part 102b becomes conducting, and the base current is supplied to the switching transistor 6 and both the resistor 7 via a resistor 104.

Title: Driving unit for actuator
Inventor: TERADA AKIO
IPC: G05D3/12
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To perform stable, high-precision transfer control of a transfer body over a wide frequency band by calculating a 1st feedback voltage with increased counter electromotive force of an actuator and setting the driving voltage of the actuator according to the difference voltage between the 1st feedback voltage and a reference voltage. SOLUTION: An impedance multiplying circuit 42 multiplies a coil current I by resistance R1 and impedance sL and adds the products to output a voltage V1=I(R1+sL). A subtracter 31 calculates the difference between the terminal voltage V=(R+sL)I+e across the actuator 3 and the voltage V1 and outputs a voltage V2=(R-R1)I+e. A converting circuit 43 outputs a voltage Vs=(R+ sL)(I+e/(R-RI)) and compares it wit the terminal voltage V, and the electromotive force (e) is multiplied by (R+sL)/(R-RI). A substracter 36 calculates the error signal between a reference voltage Vr and the voltage Vs and a substracter 39 operates the difference value from the reference voltage Vr as the terminal voltage V across the actuator 3.

Title: Manufacture of semiconductor device
Inventor: MURAMOTO SUSUMU
IPC: H01L21/306
Filed: 1982-12-10
Abstract: PURPOSE:To obtain an acute ''wedge'', which is produced by the lift-off method, and reduce the size thereof thereby to contribute to realization of an integrated circuit which is minute and high in density and speed, by depositing two different kinds of material in a groove cut in a silicon substrate by a deposition method with directivity. CONSTITUTION:Silicon oxide films 31, 31' having a thickness which is about 1/3 of the depth of the groove cut in a silicon substrate 1 are formed by an ECR- type plasma deposition method. The fragile film 31' deposited on step side wall parts (a), (a') is removed by slight etching. Silicon oxide films 32, 32' having a thickness which is about 2/3 of the depth of the groove are formed again by the ECR-type plasma deposition method. The fragile film 32 deposited on step side wall parts (a)-(a'') is removed by slight ethcing. With a resist 2 employed as a stencil 7, a lift-off operation is carried out in acetone being subjected to an ultrasonic wave. As a result, the silicon oxide film on the resist 2 is removed together with the resist 2, so that a structure is obtained in which the silicon oxide films 31, 32 are buried in the groove of the silicon substrate 1. By thus repeating the step of depositing the material and the step of etching the fragile film, it is possible to make each ''wedge'' C acute and to reduce the size thereof.

Title: Valve
Inventor: KAWAHARA HIROHITO
IPC: F16K5/06
Filed: 1995-08-24
Abstract: PURPOSE:To provide stable sealing performance by providing at least one valve seat holder with a cylindrical part and a projecting part at one edge, and pressing the back face of the projecting part by wedge mechanism positioned outside of the valve holder. CONSTITUTION:An adjusting screw rod 6 is rotated by an operating device through a joint 19 to turn an adjusting screw 6a so as to move an adjust ring 15 downward along the contact face 22. The adjust ring 15 moves a thrust ring 14 to the right so as to press the back face 11d of the projecting part 11b of a valve seat holder 11 to the right. A valve seat 9 thereby adheres closely to a valve element 4. At the same time, a valve seat 10 also adheres closely to the valve element 4. Since the valve seats 9, 10 are formed of material with high elasticity, adhesion to the valve element 4 is further heightened. When sealing performance is weakened by the repeated use of the valve element 4, the thrust ring 14 is moved further to the right by the rotation of the adjusting screw rod 6 to heighten the adhesion of the valve element 4 and valve seats 9, 10. With this structure inhibiting the entry of foreign matter, surface pressure between the valve element and the valve seat is equalized so as to be able to secure the sealing performance of a valve for a long period of time.

Title: Digital transmission path communicating system
Inventor: KAMEI JUNICHI
IPC: H04L12/28
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To continue communication between a residual base station and a central control station by changing the time slot of a succeeding base station by means of forward-jamming from a failure base station. SOLUTION: If a failure occurs in the control part of the base station 3, a bypass function switch part directly connects a transmission path B to the transmission path C and separation is executed from the control part of the base station 3 in the base station 3. Thus, the base station identification number monitoring part of the central control station 1 cannot find the identification number of the base station 3, which is assigned to TS5-TS8 of an incoming transmission path A. Then, the base station identification number monitoring part control a time slot control part so as to change the transmission path A like a TS format 43. That is, data from the outgoing transmission path A to the base station 3 is removed and data is transferred to the base station 4 through the use of TS5-TS8 by forward jamming.  In the meantime, in the incoming transmission path A, data received in TS5-TS8 is regarded as the one from the base station 4.
