Title: Noise elimination circuit
Inventor: SAITO TOMOTAKA
IPC: H03K5/1252
Filed: 1986-07-02
Abstract: PURPOSE:To eliminate bipolar noise by providing a delay means retarding an input signal, 1st and 2nd switch means and 3rd and 4th switch means subject to on/off control by the output of the delay means connected in series between the other terminals of the 1st and 2nd switch means. CONSTITUTION:The 1st and 2nd switch means Q1, Q2 are switched complementarily, the 3rd and 4th switching means Q3, Q4 are also switched complementarily and an output is obtained from a connecting point between the 3rd switch means Q3 and the 4th switch means Q4. Then the delay in a signal ea via a delay means 19 for a prescribed time against the change in an input signal ei is utilized, the 1st or the 4th switch means Q1, Q4 are used in receiving a noise to set an output terminal 20 at a high impedance state, thereby holding the preceding output data. Thus, if the noise duration is shorter than the delay time of a delay means 19, the inputted bipolar noise is eliminated.

Title: Resetting circuit
Inventor: KATAYAMA YOSHITAKA
IPC: H03K17/22
Filed: 1983-08-26
Abstract: PURPOSE:To secure the safety of a system by resetting a mu computer when a source voltage is astable and releasing the computer from being reset after the source voltage and the peripheral condition become stable. CONSTITUTION:When powered on the mu computer CP14 outputs a signal -CP according to an external clock signal. The signal -CP is outputted while lagging a signal CP until the source voltage VIN attains to its stable level, and this delay decreases as the voltage VIN approaches the stable level and is eliminated completely a specific time later. Consequently, the EX.OR circuit 16 of a resetting circuit outputs a specific voltage by exclusive OR between the signals CP and -CP. This specific voltage is applied to a terminal R of the muCP14 through a time constant circuit 17 to release the reset state.

Title: Manufacturing method of disc pad composition
Inventor: SAKATA TAKAO
IPC: C08J5/14
Filed: 1982-09-09
Abstract: PURPOSE:To prevent the inner part of a pad from gathering rust due to penetration of water or the like as well as to keep off any deterioration in the strength of the brake pad, by molding a friction member for the brake pad of a disc brake with a steel fiber coated with synthetic resins as the base material. CONSTITUTION:A friction member used for a disc brake pad is made up of a steel fiber coated with synthetic resins, for example, phenol resin (inclusive of various modified resins), melamine resin, urea resin and the like as base materials. That is to say, a surface of the steel fiber nitrified is coated with the said resins, then this coated one is mixed with a binder (phenol resin by way of example) and a filler, and molding by means of thermal pressure takes place, thus the friction member is produced. If doing like this, synthetic resins permeate through fine unevenness on the steel fiber's surface produced by the way of nitriding so that an adhesion characteristic in these synthetic resins becomes improved and moreover, with molding by thermal pressure, these resins are solidly baked to the said uneven surface, thus excellent rust preventing effectiveness can be secured.
