Title: Rectifying diodes connected in series and rectifying circuit
Inventor: AMAMYA YOSHIHITO
IPC: H01L25/11
Filed: 1980-08-15
Abstract: PURPOSE:To obtain a rectifier having high strength against damage without selecting respective diodes by providing specific relationship among the junction capacity, reverse recovery time and reverse maximum transient current of respective diodes forming the rectifier. CONSTITUTION:Diodes D1-Dn have respectively p-n junction capacities C1-Cn. When reverse maximum applied voltage VR and reverse maximum transient current iR are set under the external conditions, the p-n junction capacity values C are so set with respect to the difference DELTAtR between the maximum value and the minimum value of the reverse recovery times of the respective diodes D1-Dn as to be C>=iR.DELTAtR.n/VR. Where (n) represents the number of series diodes D1-Dn. Even if there exists inrregularity in the reverse recovery time of the diode, the reverse voltage applied during the reverse recovery transient time does not exceed the VR/n, but is equal to the reverse voltage applied in the ordinary state, and according is not damaged.

Filed: 1988-05-09
Abstract: PURPOSE:To simulate a host device by an external storage device and to execute flexible self-function test diagnosis by providing the external storage device with a function test control part and a test instruction storing part. CONSTITUTION:When an operator instructs a function test from a maintenance panel 17, a microprocessor 12 sets up the device to a diagnosis mode to inhibit an instruction from the master device 2. When the diagnosis mode is set up, the processor 12 commands a test instruction control part 15 to read out an instruction from an instruction storage part 16 and send the instruction and data to a master device connecting part 11. The instruction is transferred from the connection part 11 to the processor 12 and executed. After ending the operation of the instruction, the processor 12 requests the succeeding instruction to the control part 15. After similarly ending all instructions stored in the storage part 16, the processor 12 displays the normal end of diagnosis based upon the function test on the panel 17 and releases the diagnosis mode.

Title: Phase deviation circuit
Inventor: WADA SHIYUNICHI
IPC: H03L7/18
Filed: 1978-09-14
Abstract: PURPOSE:To obtain the output signal which is capable of having an optional phase deviation to the input signal by controlling the phase deviation angle of the PLL. CONSTITUTION:Phase comparator 10 detects the pahse difference between two input signals, i.g., the input and output signals of the PLL and then converts the difference into the voltage. This voltage is then made to pass through loop filter 20, and the stability, the response properties and the synchronous properties are decided for the PLL according to the anplitude and phase properties of the voltage. In filter 20 the inverse input terminal of operational amplifier 21 is connected to the output terminal of comparator 10, and the 1st control voltage is applied to the noninverse input terminal of operational amplifier 21A. As a result, filter operates so as to secure the equal level between the output voltage of comparator 10 and the 1st control voltage. Accordingly, the phase deviation angle between the input and output signals can be controlled freely by the 1st control voltage. At the same time, VCO30 receives the oscillation control by the output voltage of filter 20.
