Title: Testing device for pulse power
Inventor: NAGAMEGURI ISAMU
IPC: G01R31/26
Filed: 1989-05-30
Abstract: PURPOSE:To remove a defect caused by the withstanding voltage to field effect transistor by applying a voltage for flowing a constant drain current at the cycle of ON to a gate or a voltage for cutting off at the cycle of OFF. CONSTITUTION:A timing circuit 8 is constituted with an non-stable multivibrator for generating timing pulses. The power supply voltage VCC and the saturated voltage VCE of transistor Q2 in the circuit 8 are switched by the voltage VC2 of Q2. Responding to this voltage, an ON/OFF control is performed for a transistor Q3 in a reference voltage generating part 7. The power supply voltage VCC of transistor is set on a value higher than that of a drain power source VDD to be tested. A pulselike ON/OFF is made for the drain voltage since the voltage for making the constant drain current flow at the cycle of ON to the gate or the voltage for cutting off at the cycle of OFF is applied respectively, then the test for pulse power can be made without performing the pulselike ON/OFF for the drain power source VDD.

Title: Density gradation control type thermal printer
Inventor: FURUHASHI YOSHIHISA
IPC: B41J2/36
Filed: 1987-05-30
Abstract: PURPOSE:To reduce by one half the number of line buffers being used, by once writing all of first and second sets of density data into one line buffer, and simultaneously distributing both sets of density data respectively to first and second latchcircuits at the time of reading. CONSTITUTION:For simultaneous serial transfer of gradation data to first and second sets of heat generating resistor elements, data supplied from a color process circuit 22 as a basis for gradation data is divided into first and second sets, and all of the first and second sets of data are once written into a single line buffer 50. At the time of reading, the two sets of density data are simultaneously outputted on a time sharing basis, and are distributed to latch circuits 28, 30. The density data thus latched are sent to a data-comparing circuit 32, 34, where the data are converted into respective gradation data by a count pulse CP, and are simultaneously transferred on a serial basis to the first and second sets of heat generating resistor elements R1-R256, R257-R512. Thus, the number of line buffers used can be reduced by one half.

Title: Control signal transmission system
Inventor: YANAGIDA IKUO
IPC: H04J1/00
Filed: 1988-06-06
Abstract: PURPOSE:To make data transmission efficient by sending a control signal without inserting a control signal causing excess redundant bit into a data. CONSTITUTION:A pulse generating circuit 1 generates a signal (b) of a specific pattern with different frequency band from that of a data signal (a) corresponding to each control item and the signal (b) of the specific pattern and the data signal (a) are added digitally by an adder circuit 2 and only a required signal (d) among the added signals is sent by a control circuit 3. Then the signal (d) is separated into the data signal (a) and the signal (b) of the specific pattern by a pattern detection circuit 4 at the reception side. Thus, the operation of inserting the control signal causing the excess redundant bit into the data is not required. Then the data transmission is made efficient.

Title: Vertical crystal resonator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/19
Filed: 1987-06-02
Abstract: PURPOSE:To obtain a vertical crystal resonator without generating oscillation leakage entirely, by forming an oscillation part and a supporting part integrally by an etching method, enclosing a resonator with a refraction part connected to the oscillation part, and connecting the refraction part to a frame opposite to a mounting side. CONSTITUTION:The resonator 1 is constituted of the oscillation part 2 and the supporting part 3, and are formed integrally by the etching method. The oscillation part 2 performs expanding/compress ing motion in a longitudinal direction by electric field driving from the outside, and also, simultaneously, performs the same motion in the direction of a bridge part 4 that a perpendicular direction. And it is possible to prevent the suppression of oscillation in the longitudinal direction by a ratio of the length L to the width W of the refraction part 5 of the supporting part 3 from being generated. Next, as a countermeasure for the oscillation leakage, the oscillation part 2 and the refraction part 5 are formed integrally via the bridge part 4, and its end part is connected to the frame 6. At this time, the refraction part 5 performs the oscillation having such boundary condition that one end is fixed and the other end is supported. In such a way, by increasing the mass of the frame 6, energy is confined at the tip part of the supporting part 3, and no oscillation leakage is generated entirely even when the resonator is fixed on a mounting part 7.
