Abstract: PURPOSE:To decrease the number of automatic gain control circuits by providing variable gain amplifier circuits compensating the loss of two IF cables respectively, and one automatic gain control circuit controlling the gain of the variable gain amplifier circuit in common, in either the transmission/reception section or the modulation/demodulation section. CONSTITUTION:When an IF signal is sent from a modulation demodulation section 7 to an input section 8A of a transmission reception section 6, an IF signal inputted to the transmission reception section is amplified by a variable gain amplifier 1 whose output level is controlled to be constant by an automatic gain control circuit(AGC) 2 to compensate the loss by a cable 5. On the other hand, when the IF signal is sent from an output section 9B of the transmission reception section 6 to a modulation demodulation section 7, the IF signal is amplified up to a level to compensate the loss due to the cable 5 in advance by the variable gain amplifier 1, and kept to a specified level in the input section 9A of the modulation demodulation section 7. That is, since the IF cables 5 are of equal length, the level of both the IF cables 5 is compensated by the AGC circuit 2.

Title: Semiconductor device and manufacture thereof
Inventor: FUKUSHO TAKASHI
IPC: H01L23/522
Filed: 1994-07-23
Abstract: PURPOSE:To prevent the interface state density of a semiconductor substrate from being insufficiently eliminated, by bring a metal wiring layer into contact with the semiconductor substrate or other metal wiring films through a plug film having a base of a tungsten silicide film as an adhesion layer. CONSTITUTION:An adhesion layer 6, composed of tungsten silicide, formed by CVD, enhances the adhesion of a plug film 7. The plug film 7, composed of tungsten, is formed by filling contact holes 5 using the adhesion layer 6 as a base. A metal wiring layer 8 is electrically connected with a semiconductor substrate 1 through the plug film 7. This prevents the insufficient elimination of the interface state density of a semiconductor substrate, which used to be the case because hydrogen is occluded in an adhesion layer to be the base of a metal layer.

Title: Speed change gear equipped with power taking-out device
Inventor: ENOMOTO KOJI
IPC: B60K17/28
Filed: 1986-08-20
Abstract: PURPOSE:To prevent the generation of breakage and impact noise when each gear is in engagement by permitting a driving side gear and a trailing side gear to be meshed only in the case when the revolution speed of the driving side gear in a power taking-out device is below a prescribed value. CONSTITUTION:The driving power of an engine 10 is transmitted to a turbine shaft 14 through a torque converter 12, and further transmitted to an output shaft 18 through a speed change mechanism 16. If, in this case, the revolution speed of a driving side gear 20 which is input from a revolution speed detector 18 is below a prescribed value, a controller 36 outputs a signal for turning-ON a solenoid valve 34 only in the case when a power taking-out device operating switch 40 is turned ON. Therefore, when the driving side gear 20 revolves at the higher speed over a prescribed value, the solenoid valve 23 is kept in the turned-OFF state even if the operation switch 40 is turned ON. Therefore, an oil pressure is supplied into the oil chamber 32 of a hydraulic cylinder 26, and since a trailing side gear 22 is at the disengagement position with the driving side gear 20, a prescribed purpose can be achieved.
