Title: High frequency heater
Inventor: YOSHINO KOJI
IPC: H05B6/64
Filed: 1987-10-30
Abstract: PURPOSE:To facilitate the recognition of an output during cooking operation by providing a power converter, performing switching actions by means of control signals to control an input current, and displaying according to the control signals. CONSTITUTION:An input current from a power source section 10 is inputted to a detection means 15 and a current converter 11. A detection signal detected with the means 15 is inputted to a control section 13. To the control section 13 is also inputted a setting value as a control signal from an input control section 14. The control section outputs the detected signal to be inputted to the converter 11. The converter 11 changes the above-mentioned input current into high frequency power. The converter 11 also changes switching frequency and on-off time of a conductor element by means of the inputted control signal to make the magnitude and the mean value of the input current coincide with setting values. The converter 11 also emits an output as electromagnetic wave energy through an electromagnetic wave emitting section 12. As the control signals are displayed on an action display section 16, an operator can recognize the extent of progress of a cooking.

Title: Composite heat sink
Inventor: DAVIS DWIGHT MACLAREN
IPC: H01L23/427
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a heat sink having a heat transmission medium for enhancing the heat transmission capability of the heat sink. SOLUTION: A heat sink 10 has a plurality of fins 14 having cavities, a base 12 and a fluid heat transmission medium 16. The fin 14 is in thermal contact with the base 12 and is constituted so as to form a series of longitudinal flow path for passing air or the fluid medium. The fluid heat transmission medium 16 is contained in the respective cavities. The fluid heat transmission medium 16 intensifies the heat transmission capability of a heat sink 10 without enlarging the surface area, the size and/or the weight of the heat sink 10. When evaporated fluid heat transmission medium 16 condenses at the upper cooling wall of the fin 14, a large quantity of energy is transmitted from the evaporated fluid heat transmission medium 16 to the film 14. Thus, a larger quantity of the heat can be transmitted from the fluid heat transmission medium 16 to the fin 14, and then the fin 14 is able to diffuse the heat to the low-temperature surrounding part.

IPC: G01R27/02
Filed: 1986-11-21
Abstract: PURPOSE:To find an insulation resistance after the influence of an overvoltage is removed by applying plural voltages which differ in value between a circuit to be measured and the ground and processing the results statistically. CONSTITUTION:A conductor 5 and an electrode ring 6 are connected to the secondary winding 4 of a power source part 1 and the electrode ring 6 presses a material 7 to be welded, so that it is welded with a large current. An insulation measurement part 9 is connected to the conductor 5 through a contactor 8. The measurement part 9 consists of a variable voltage power source 10 which has its plus side connected to the contactor 8 and its minus side grounded, a voltmeter 11 and an ammeter 12 connected thereto in parallel, and a unit 13 which calculates the insulation of the conductor from a detection voltage and a detection current. The voltage of the power source 10 is varied to, for example, 5, 10 and 15V and the current is measured by the ammeter 12. The arithmetic unit 13 generates V=IXalpha+beta from the current value by a minimum squaring method. When the current I varies to 0.2, 0.3, and 0.4, alpha=50OMEGA and beta=-5V are found so the insulation resistance (a) is found. The insulation resistance is accurately fund by this method while the influence of an overvoltage is removed.

Abstract: PURPOSE:To make it possible to obtain accurate data by receiving the data from a ground apparatus, storing the demodulated signals back to the past, adding the signals for every same bit, and performing majority judgment for the obtained values for every bit. CONSTITUTION:A received signal Sa is demodulated in a Differential-Phase-Shift Keying (DPSK) demodulating circuit A, and a demodulated signal Sb is led out. The signal is supplied into a Barker-code detecting circuit B and a shift register/latch circuit D. In the circuit D, shifting of the signal Sb is performed in response to a sampling pulse Sd, and latching of the signal Sb is performed in response to a sampling pulse Se. Then, the demodulated signal Sf is stored in a synchronous adding means E. The signals are added for every same bit for the specified period in the past. The added result Sg is supplied into a majority judging means F. Then, majority judgment is performed in the means F, and the demodulated data Sh are outputted. In this way, the data error rate is decreased by performing the majority judgment, and the basic data and the auxiliary data having the high accuracy are obtained in the wider region.

Title: Phase control circuit for motor
Inventor: UEHARA MASAHIRO
IPC: G11B19/28
Filed: 1985-12-11
Abstract: PURPOSE:To reduce a time between the start up time of a motor and a time possible to record by resetting the division timing of a phase difference detecting signal so as to equalize phase locked points just before switching a phase control from the control by a vertical synchronizing signal to the one by a horizontal synchronizing signal in a start up time. CONSTITUTION:After the phases of a reference position pulse signal PG and a vertical synchronizing signal VD are made approach in a certain range with the first phase control system, a system is switched to the second phase control system switching the side of the first phase comparison circuit 7 to that of the second phase comparison circuit 12. At such a case, since the phase locked points in the first phase control system and in the second phase control system are not necessarily coincided, the phase locked points in both systems are equalized by controlling the division timing of a division signal (HD/n) by a division circuit 10 with a reset circuit 16. Thereby, the motor is started up, and the time until when a state that a recording can be performed on a magnetic sheet is generated can be reduced, therefore, the recording can be performed in a requested recording time without delay.
