Title: Crystal oscillation circuit
Inventor: ISHIKAWA TAKEHIRO
IPC: H03B5/36
Filed: 1978-05-09
Abstract: PURPOSE:To prevent incapability of the oscillation due to the evil effect of dust, water drops or the like by surrounding the periphery of the circuit pattern at the input side of the amplifier circuit in the C-MOS inverter with the circuit pattern featuring the constant voltage potential. CONSTITUTION:When a leakage occurs between VSS pattern 41, guard pattern 40 and oscillation circuit input pattern 39, the connection shown by resistance 42 and 43 is secured between them. In other words, drain current ID of P-ch transistor Tr32 starts to flow when resistance 42 and 43 decreases down to some extent. And with increment of the degree of leakage, ID increases. Then the potential of pattern 40 becomes constant near VDD/2 when the threshold voltage of Tr32 is about 1/2 power source VDD. Thus, inverter 34 is biased to about VDD/2 level, and the bias point is fixed forcedly by the leak resistance between pattern 40 and 39 even with the leakage of such degree that the oscillation is stopped. As a result, the oscillation never stops. In this connection, the guarding can be secured with the constant voltage circuits of P-chTr in case pattern 39 and 41 are put close and in case pattern 39 and 40 are put close respectively.

Abstract: PURPOSE:To make a central unit select only one specified terminal equipment by providing a means for adding a prescribed value to an address selecting signal which is applied to the terminal of an address bus input side and sending it out to the terminal of an output side on plural terminal equipments. CONSTITUTION:A central unit CU sends out in parallel the address code of an address selecting signal for designating an optional terminal unit TU, to (m) pieces of address buses l0-lm-1. The adder AD of the cascaded terminal unit TU adds a prescribed value to each inputted address code and sends it out to the next terminal unit TU. Accordingly, each different address code is inputted to each terminal unit TU, therefore, the central unit CU can select a specified terminal unit TU. In general, in case when the addition of +1 is executed by each terminal unit TU by using the address code of (m) bits, when selecting the x-th terminal unit TUX-1, it may be sufficient that the central unit CU sends out the address code of an address selecting signal (2<m>-x).

Title: Sawtooth voltage generation circuit
Inventor: TAKAHASHI KIYOSHI
IPC: H04N3/27
Filed: 1990-03-06
Abstract: PURPOSE:To decrease the current proof of a convergence output circuit and a power source circuit for the circuit by generating a sawtooth signal whose amplitude is kept constant in spite of the change of a deflecting frequency. CONSTITUTION:An integration circuit 21 forms a sawtooth voltage at an output terminal 5 by performing a charge/discharge operation by output from a frequency voltage conversion circuit 6 and an inversion amplifier 24. The amplitude of the sawtooth voltage is proportional to the product of the integral action time of the integration circuit 21 and a current outputted from a power source for charge/discharge. The integral action time decides the short inclination period and the long inclination period of the sawtooth voltage, and it is inversely proportional to the deflecting frequency, and the output current of the power source for charge/discharge is proportional to the deflecting frequency, therefore, the amplitude of the sawtooth voltage can be kept constant in spite of the deflecting frequency (frequency of flyback pulse). In such a way, it is possible to use the convergence circuit or the power source circuit for the circuit with low current proof.
