Title: High frequency heating device
Inventor: SANO MASAKAZU
IPC: H05B6/68
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To enhance the power factor of a high frequency heating device. SOLUTION: In this high frequency heating device, an inverter circuit for controlling an electric power supply from an alternating power source 1 to a transformer 9 is composed of a capacitor 7 and a switch element 8. A power factor improving circuit 17 controls the oscillated frequency of the inverter circuit in accordance with an absolute value of the voltage of the alternating power source 1.

Title: Source coupled type fet circuit
Inventor: SAITO SUMIO
IPC: H03K19/094
Filed: 1988-02-25
Abstract: PURPOSE:To obtain a output signal of a 1st FET Q1, an output signal of a 2nd FET Q2 and to obtain a signal with less ringing similarly by providing a voltage drop means to a drain of the 2nd FET so as to reduce the drain- source voltage at the ON-state of the 2nd FET. CONSTITUTION:The voltage drop means is inserted to the drain of the 2nd FET Q2 to drop the drain-source voltage at ON of the 2nd FET Q2. That is, the voltage drop means comprising a parallel circuit consisting of a resistor R3 and a capacitor C1 is inserted. Thus, the resistor R3 is selected so that the drain-source voltage VDS at ON state of the 2nd FET Q2 is nearly OV, then the drain potential of the FET Q2 is dropped and the drain-source voltage at ON state of the FET Q2 is nearly OV. Thus, even if ringing takes place, since the deflection toward the negative direction is suppressed, the waveform with less ringing is caused.

Title: Forming of nonspherical lens
Inventor: ONISHIMA MASABUMI
IPC: C03B11/08
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a nonspherical lens by which a strain is hardly caused in a part in the form of the nonspherical lens and a residual stress can be relaxed to suppress the damage and improve the accuracy. SOLUTION: A molten glass is formed with a top force part 11 and a bottom force part 18 of a forming metallic mold 10 to form a formed product 23 in a cup shape having a part 22 in the form of the nonspherical lens formed at the bottom 25. The part 22 in the form of the nonspherical lens of the formed product 23 is subsequently repressed with a repressing machine and the thermal stress relief of the part 22 kept in the form of the nonspherical lens in the intact cup shape is then carried out. Since the nonspherical lens is cut from the part 22 in the form of the nonspherical lens thereafter, the heat on the inner side surrounded by a sidewall part 28 hardly escapes when placing the formed product 23 in an annealing furnace and performing the thermal stress relief and the strain in the part 22 in the form of the nonspherical lens is readily removed to relax the residual stress.  Thereby, the damage is hardly caused to enable the forming of the nonspherical lens improved in the accuracy.

Title: Mos transistor
Inventor: HIGUCHI MITSUMASA
IPC: H01L21/336
Filed: 1990-02-22
Abstract: PURPOSE:To prevent the generation of a voltage drop due to a low-concentration diffused layer by a method wherein an intermediate diffused layer is provided between the low-concentration diffused layer in a source region and a high- concentration diffused layer in a drain region. CONSTITUTION:Low-concentration P, medium-concentration As and high- concentration As are implanted in order in the transverse direction of a gate 1 on a wafer 10 and a drive treatment is performed to form an N<+> layer 3, an N-type layer 7 and an N<+> layer 4. In a MOS transistor of an LDD structure of this constitution, the region of the N<-> layer for performing a relaxation of an electric field is suppressed to the minimum. Thereby, a voltage drop due to the N<-> layer can be prevented and the improvement of a source-drain current can be contrived. Accordingly, even a transistor having a gate of a dimension identical with that of the gate 1 can be obtained a transistor performance higher by one rank.

Title: Controller for clutch
Inventor: AOKI TAKASHI
IPC: F16D48/06
Filed: 1994-02-17
Abstract: PURPOSE:To stably transmit creep force in stopping a vehicle by reducing a prescribed negative pressure from detected real intake negative pressure so as to calculate the target negative pressure in idling under an untraveling range and controlling clutch engaging force in such a way as matching the real intake negative pressure with the target negative pressure in idling in a traveling range. CONSTITUTION:When a shift position is shifted from N or P range to D range in an intake negative pressure feedback mode, a target intake negative pressure corresponding to engine intake negative pressure under such a load condition that a prescribed weak creep force is generated, is calculated and set based on an immediately prior intake negative pressure just before shifting. The connection operation pressure from a clutch control valve 75 is feedback controlled in such a way that the real intake negative pressure after shifting a shift position approaches to the target intake negative pressure. Even if frictional coefficient of a clutch lining of a start clutch 5 is dispersed, a prescribed weak creep force is thus transmitted stably to the drive wheel so as to prevent vibration of a car body and prevent aggravation of fuel consumption in stopping.

Title: Arc power unit
Inventor: MATSUDA SHINZABURO
IPC: G05F1/08
Filed: 1988-02-26
Abstract: PURPOSE:To obtain a stable arc power unit by using the AC output voltage of an AC control thyristor switch as a feedback signal to control the voltage. CONSTITUTION:The phase control angle of an AC control thyristor switch is controlled by an AVR of a block 12 so that a feedback signal 51 is equal to a reference signal 52. The signal 51 corresponds in 1:1 to the phase control angle regardless of the output current of the AC control thyristor switch. While the voltage level of a load terminal is lowered as the output current increases despite the same phase control angle since the voltage drop due to the impedance component of an insulated transformer is different according to the level of the output current. As a result, the output voltage is suppressed by the voltage drop equal to the impedance of a transistor in case the arc current tries to increase after the start of the arc discharge. Thus the arc current is stabilized.

Title: Measuring instrument for propagation time of surface acoustic wave
Inventor: SUSHI HANJI
IPC: G01N29/00
Filed: 1985-03-07
Abstract: PURPOSE:To improve measurement accuracy by calculating the propagation time of a surface acoustic wave from a target body on the basis of data from a counter which measures the time between the reflected wave of its transmitted wave from the target body and an arrival wave from another electroacoustic transducer. CONSTITUTION:An electric pulse signal is impressed to two electroacoustic transducers 10 and 11 at the same time; the time from the transmission of a signal from one transducer 10 to the arrival of a reflected signal from the target body 2 is denoted as 2T1 and the time to the arrival of a signal from the other transducer 11 is denoted as T. Values measured by the other transducer 11 are also denoted as 2T2 and T as well. Counters 22 and 23 calculate T3=T-2T1 and T4=T-2T2. Consequently, T0=(T3+T4)/2, where T0 is the propagation time in the target body. Therefore, the values of the two counters are averaged by an arithmetic circuit 24 to obtain the propagation time in the target body. Thus, the measurement accuracy is improved and measuring operation is facilitated.
