Title: Digital-to-analog converter
Inventor: RUDEI YOHAN FUAN DE PURATSUSHI
IPC: H03M1/00
Filed: 1982-05-06
Abstract: In a digital-to-analog converter for bipolar signals all the bits change when the signals pass through the zero level. This results in a poor signal-to-noise ratio owing the small signal and the large noise contribution by the switching transients. The invention proposes to add a digital number to or subtract it from the digital input signal as an offset. As a result of this, the switching point is shifted towards a higher amplitude, which improves the signal-to-noise ratio and the distortion in the case of digital audio signals.

Title: Drive circuit for insulated-gate type power semiconductor element
Inventor: IKEDA TETSURO
IPC: H02M1/08
Filed: 1992-02-26
Abstract: PURPOSE:To prevent the malfunction of an insulated gate type power semiconductor element by noise by providing a switching semiconductor element which is turned on when the power semiconductor element is turned off and holds a gate voltage at a backward bias voltage by forming a discharging path to a capacitor. CONSTITUTION:In the title drive circuit, a switching semiconductor element 4 is turned off and another switching semiconductor element 23 is turned on when a power semiconductor element 1 is turned off. When the element 4 is turned off, electric power of a backward voltage polarity is induced across a primary winding 3a and disappears, because the voltage is discharged from a loop composed of the one end of the winding 3a, a resistor 6, a diode 5, and the other end of the winding 3a. The electric power of the backward voltage polarity is also induced in a secondary winding 3d and a gate driving section 12 is actuated. As a result, the unnecessary charges of a stray capacitance are discharged and the gate voltage drops, resulting in the turning off of the element 1. Then the gate voltage is maintained at a negative level and is deeply biased backward. Therefore, the gate voltage does not rise to a threshold even when the gate voltage fluctuates due to a noise voltage and malfunction of the element 1 by noise can be prevented.

Title: Friction material for brake
Inventor: IMAO MAKOTO
IPC: B29C43/02
Filed: 1983-04-30
Abstract: PURPOSE:To prevent the occurrence of warping by molding a friction material into a nearly U-shaped groove form in a manner that an almost rectangular contact face to be touched by a sliding object is traversally divided into two section. CONSTITUTION:A fibrous base material is mixed with an abrasion characteristic improver and a filler and then with a phenolic resin binder in a hot molten state to obtain a mixture 4.

Since the difference in the dimension between the vertical and cross sections of the friction material so divided is less, the occurrence of warping can be prevented. The friction material 1 is finally bonded to a back plate 2 in a pressing manner.
