IPC: H03K3/02
Filed: 1982-08-24
Abstract: PURPOSE:To obtain an initializing signal forming circuit suitable for an IC, by forming a minute-capacity capacitor internally and controlling the charging of the capacitor by a switching element which is controlled by the amplitude of oscillation. CONSTITUTION:When several hundred ms elapse after power-on, the oscillation of an oscillating circuit (consisting of Xtal, G1 and R) which becomes the steady oscillation state after the elapse of a certain time from power-on is increased gradually, and the output becomes L when the oscillation exceeds the threshold level of an inverter G2. The first FETP1 is turned on, and a capacitor C is charged with a prescribed time constant, and a voltage Vc of the capacitor C rises; and when it exceeds the threshold level of an inverter G5, a set signal becomes L to make a reset signal effective, and an initializing signal In is changed from H to L to terminate the initialization. Consequently, a CR time constant circuit for initialization is unnecessary in the external of the IC, and the reliability is improved considerably.

Filed: 1990-06-04
Abstract: PURPOSE:To prevent a negative pressure from being developed inside a pipe, the sealing effect of a drain trap from being spoiled, and the pipe from being blocked by rubbish such as waste threads, by a method wherein an internal bottom face 15a in the middle of a bend pipe in the axial direction has a smaller radius than that of an internal upper face and the both internal faces are connected together by curved planes of side walls so that the section is almost an oval shape. CONSTITUTION:An internal bottom face 15a in the middle of a bend pipe 1 in the axial direction has a smaller radius than that of an internal upper face 16a and the both faces 15a and 16s are connected together by side walls of curved planes 17a and 17b so that the section is almost an oval shape. When drain water flows down from a rising pipe 2 into the bend pipe as it swirls, the drain water is restrained from swirling by the internal bottom face 15a of the bend pipe 1 and the drain water which swirls inside the pipe strikes on each other so that the drain water loses its swirling energy. Therefore, the drain water does not rise up to the upper parts of the internal faces of both side walls 17 and flows down into the lower part of the bend pipe 1 so that a negative pressure is not developed inside the rising pipe 2.

Abstract: PURPOSE:To prevent malfunction due to the fluctuation of a power supply potential by separating power wiring connected to each transistor (TR) from the 1st stage to a preceding stage from a power wiring connected to each TR circuit from the preceding stage to the post-stage. CONSTITUTION:The 1st stage switching circuit consists of FETs Q31, Q32, the 2nd stage switching circuit consists of FETs Q41, Q42, and the 3rd and succeeding stages consist of the post-stage switching circuit Y.
