Filed: 1985-11-05
Abstract: PURPOSE:To make it possible to impregnate a base material with a resinous liquid uniformly and efficiently/by impregnating a long size material with the resin just after preceding pressure application, pressing the base material by required times in the impregnating bath, and moving the base material through squeeze rolls. CONSTITUTION:For example, a long glass cloth is used as a base material 1. The base material 1 is pressed continuously by a pressure device 3 just before the impregnation of a resin. While most of air bubbles are expelled from the base material, the resinous liquid 2 is impregnated into the base material 1 but some bubbles still remain. Next, the base material 1 is pressed by the pressure device 5 in the impregnation bath and a small amt. of bubbles left behind are also completely expelled from the base material 1. The base material 1 which no bubble moves, while the quantity of the impregnating resin is controlled through the squeeze rolls 6. Thus, the base material impregnated with the resin 7 containing no bubble is dried in a drying process into a prepreg. A laminate, a printed-wiring board, a decorative sheet and so on can be obtained by laminating and molding this prepreg.

Title: Speed signal input circuit
Inventor: TSUNODA TORU
IPC: F01D19/00
Filed: 1990-09-19
Abstract: PURPOSE:To obtain a speed signal input circuit for eliminating influence of noise with no influence on control property by providing, in the input part of a control device a self-diagnostic judging circuit for eliminating influence of a signal caused by noise so as to transmit an optimum signal to the control device. CONSTITUTION:The revolution of a turbine is detected by a revolution number detector 1 so that a pulse signal is generated and the pulse signal is converted by a signal converter 11 so that a speed signal (S) is obtained. In a judging circuit 12, the speed signal (S) is compared with a speed increase control amount (A), a load set value (L), and a turbine inlet pressure (P) so as to judge whether the speed signal (S) is in the control range of each of control signals (A), (L), and (P). As a result, if the speed signal (S) is considered to have an optimum input value, it is outputted as a control signal (S1). On the other hand, when the speed signal (S) is considered to have an abnormal input value outside the control range, the speed signal (S) is neglected to estimate an optimum input value by each of control signals (A), (L), and (P) so that it can be outputted as the control signal (S1). An operating signal (V) is outputted from a speed increase control unit 16, and a constant speed control unit 17 by the control signal (S1).

Patent JP-S6489564-A (JP)
Title: Semiconductor device
Inventor: OGAWA KENJI
IPC: H01L29/739
Filed: 1987-09-30
Abstract: PURPOSE:To provide a semiconductor device having good characteristics, such as FET's low-voltage linearity and high-speed capability, and bipolar transistor's low resistance property, by preparing a region in parallel to a vertical IGFET's drain region of a different conductivity and connecting the drain region to a drain electrode through a resistance region. CONSTITUTION:A drain includes a P<+> region 5 and an n<+> region 6 covered completely with a resistance region 4. The resistance region 4 and the P<+> region 5 are connected through an aluminum layer which forms a drain electrode 7-1. As the current 10 flowing through the n<+> region 6 and the resistance region 4 increases, the voltage drop across the resistance layer increases, and the n<+> region 6 and the whole n-region 12 become lower in potential than the P<+> region 5. When the difference in potential between the P<+> region 5 and the n-region 12 is about 0.6V, the P<+> region is biased forward to begin IGBT operation and a current 11 flows. Since a current flows through the P<+> region 5 thereafter, the effect of the resistance region 4 disappears, thereby providing low-resistance property.
