Patent JP-S62249488-A (JP)
Title: Compound semiconductor device
Inventor: SAIDA HIROJI
IPC: H01L29/80
Filed: 1986-04-23
Abstract: PURPOSE:To improve FET characteristics such as mutual conductance by employing an undoped semi-insulating substrate which does not contain impurity for insulation as a semi-insulating substrate. CONSTITUTION:An undoped semi-insulating substrate which is not doped with impurity for insulation such as Cr is employed as a semi-insulatin GaAs substrate 5. This semi-insulating GaAs substrate 5 is formed by a liquid enclosed Czochralski (LEC) method and shows high quality such as low etching pit density. Moreover, a buffer layer 6, an active layer 7 and an ohmic contact layer 7 which are formed on the main surface of the semi-insulating GaAs substrate 5 successively are formed by an organic metal epitaxial growth (MOOCVD) method respectively with uniform quality. Therefore, the thickness of the buffer layer 6 is so selected as to be thicker than the thickness at which the electron mobility in the aotive layer 7 starts declining suddenly and thinner than the thickness at which the leakage current in the buffer layer 6 appears or starts increasing suddenly.

Title: Differential amplifier
Inventor: FUJITA YASUHIRO
IPC: H03F1/56
Filed: 1979-07-19
Abstract: PURPOSE:To avoid the gain reduction caused by the base bias resistance, by producing the compensating current which offsets the base current of the transistor in the differential amplifying circuit. CONSTITUTION:TR16 having the same polarity and the same characteristics as the collector circuit of transistor (TR)2 for differential amplifier is connected longitudinally to the said collector circuit. In addition, the current amplifier (current Miller circuit) formed by diode 17 plus TR18 having the opposite characteristics to TR2 is connected to the base of TR16. As a result, the compensating current of the same level as the base circuit of TR2 flows to the said base circuit, and thus the compensation signal is generated at base bias supplying resistance 12. With this compensation signal, the effect due to resistance 12 can be offset to avoid the gain reduction. Furthermore, the effect of resistances 15 and 11 can be eliminated by providing the compensating current generating circuit also to TR1.

Title: Vehicle mounted acoustic system
Inventor: TAZAKI SATORU
IPC: H04R5/02
Filed: 1988-04-14
Abstract: PURPOSE:To obtain a preferable sound field to even a listener in a rear seat by providing a couple of right/left auxiliary speakers fitted to the rear face of a front seat. CONSTITUTION:A small sized speaker 2 is embedded in the rear side of a front seat 3 as an auxiliary speaker 2. That is, without the auxiliary speaker 2, the direction of sound source is biased to the right side of the front door speaker for a listener in the left rear seat and the sound source is biased to the left side of the door speaker for the listener at the right seat. This is caused because the front seat shuts off sound. Thus, the auxiliary speaker 2 is added to the rear side of the front seat. Thus, a biased sound image is prevented.

Title: Steam regulating valve
Inventor: SHINDOU KURA
IPC: F01D17/10
Filed: 1978-07-31
Abstract: PURPOSE: To prevent the abnormal wear and break of a valve stem due to the vibration of a valve element, by shaping the valve element like a column so that the valve element can be rotated around its axis at steam chambers.  
     CONSTITUTION: The columnar valve element 22 is located between the steam chambers 21 and nozzle chambers 20 and supported on the wall 24 of a casing so that the valve element 22 can be rotated around its axis. A pinion 25 is provided on one end of the valve element 22 and engaged with a rack 27 on the tip of a piston rod 26a of a servomotor 26. Grooves 28 are provided on the peripheral part of the valve element 22 to connect the steam chambers 21 to the nozzle chambers 20. When a driving signal is applied to the servomotor 26, the valve element is rotated to set an output flow rate almost proportional to the signal. The valve element is thus prevented from being vibrated by the impulsive force of steam flow. Therefore, troubles due to the vibration are eliminated.
