Title: Phase locked loop circuit
Inventor: KAMEI TAKAHIRO
IPC: H03L7/093
Filed: 1988-11-09
Abstract: PURPOSE:To remove deviation between the direct current component of the output of a phase comparator and reference voltage by generating the reference voltage by a reference voltage generation circuit by using the positive-phase output and the negative-phase output of a phase comparator, and supplying this reference voltage to a loop filter as bias voltage. CONSTITUTION:The phase comparator 40 is constituted of a bipolar ExOR to compare the phases of an input signal with a feedback signal and send the positive-phase output and the negative-phase output corresponding to this compared result. The reference voltage generation circuit 50 generates the reference voltage of a prescribed level based on the positive-phase output and the negative-phase output, and supplies this reference voltage to the loop filter 60. The phase comparator 40 of bipolar constitution enables high-speed operation, and the reference voltage generation circuit 50 generates the reference voltage corresponding to the change of the direct current component of the output of the phase comparator 40, and supplies this reference voltage to the loop filter 60 as the bias voltage. Thus, the deviation between the direct current component of the output of the phase comparator 40 and the reference voltage is eliminated.

Title: Refreshing method for semiconductor storage device
Inventor: ADACHI YUKINOBU
IPC: G11C11/34
Filed: 1986-11-26
Abstract: PURPOSE:To attain refreshing by bringing the inverse of a CAS signal into a low level while the inverse of a RAS signal strobing a row address and the inverse of the CAS signal strobing a column address are both at a high level. CONSTITUTION:At the standby state where both the inverses of RAS, CAS are at high level, a transistor (TR) 4 is turned on, an external signal is inputted to an address buffer, '1' is inputted to the inverse of RAS buffer circuit. When the inverse of the CAS goes to 0, the relation of the inverse of REF=0, REF=1 exists and 0 is inputted to the inverse of RAS buffer circuit and the internal signal is changed. The signal REF outputted to an integration circuit 7 changes from 0 to 1, but the output of the circuit 7 smoothly rises, a delay time (t) is required to allow an AND circuit 6 to receive a high signal. When the output of the integration circuit 7 exceeds V1H, it is regarded as a high level, the output from the AND circuit 6 is '1' and a TR 5 is turned on. Thus, an internal counter signal is inputted to an address buffer and refreshed.

Title: Automatic gain control high frequency amplifier
Inventor: TERAJIMA AKIYOSHI
IPC: H03G3/30
Filed: 1989-10-31
Abstract: PURPOSE:To suppress the harmonic distortion for transition by controlling the extent of attenuation of a variable attenuator to its maximum to minimize the output of an amplifier at the time of transition of a supply voltage to a set value. CONSTITUTION:Until the voltage supplied to a high frequency amplifying circuit 3 reaches the steady value, an abnormality signal is sent from a voltage detecting circuit 7 to a gain control circuit 6, and the extent of attenuation of a variable attenuator 4 is controlled to its maximum to minimize the output of the high frequency amplifying circuit 3. When the voltage reaches the steady value, a normalcy signal is sent from the voltage detecting circuit 7 to the gain control circuit 6, and the output of the high frequency amplifying circuit 3 is gradually increased to follow up the set output. Thus, the operation point of the amplifying circuit 3 is prevented from approaching the saturation output though the supply voltage is not sufficient and the saturation output of the amplifying circuit 3 is small, and the harmonic distortion for transition is suppressed.

Filed: 1992-09-28
Abstract: PURPOSE:To save power at recording by forcibly increasing a cathode drive signal of a CRT at recording so as to make a screen dark thereby allowing a video image to disappear. CONSTITUTION:A recording start signal is fed to an anode terminal of a Zener diode ZD6a in a picture erasure circuit 6, an anode potential of the ZD6a reaches a +B power level, the ZD6a is conductive and a transistor(TR) 6b is conductive. As a result, the potential at an output terminal 1a is raised to the +B power level and a TR 2 is cut off. Thus, a +B voltage is applied to an output TR driving the CRT cathode. Thus, the beam current flowing to the cathode of the CRT is cut off, the CRT screen gets dark and the video image displayed on the CRT screen disappears.

Title: Inspecting method of printed circuit board
Inventor: SATO SATOSHI
IPC: G01R1/06
Filed: 1988-11-11
Abstract: PURPOSE:To prolong th e lifetime of a spring pin by inserting a junction pin between the spring pin and a probe pin so that a force in the vertical direction be always transmitted to a probe electrode pin itself or the spring pin connected to the probe electrode pin. CONSTITUTION:A probe pin 27 and a junction pin 22 are interposed between a terminal electrode at an off-grid position of a printed circuit board 8 and a head part 4A of a probe electrode pin 4. By applying a pressing force from above the printed circuit board 8 in this state, the probe pin 27, the junction pin 22 and the probe electrode pin 4 are connected electrically in this order without fail. On the occasion, a spacer 23 with a spring is also contracted, so that unnecessary lateral weighting to the probe pin 27 be reduced. The lateral weighting is given to the junction pin 22, since the probe pin 27 is inclined. However, the junction pin transmits the force to the head part 4A of the probe electrode pin 4 in the vertical direction invariably, and therefore no lateral weighting is applied to the probe electrode pin 4 which is a spring pin.
