Title: Pre-compensation system for ringing
Inventor: ONISHI MAKOTO
IPC: H04N5/14
Filed: 1989-12-22
Abstract: PURPOSE:To facilitate the ringing compensation of a part difficult to compensate in the viewpoint of circuit technique by executing pre-compensation by connecting a ringing compensation circuit to the preceding stage of a filter to cause ringing. CONSTITUTION:The ringing compensation circuit 1 is inserted in the preceding stage of the filter 7 which is intended to be ringingcompensated. Then, an input signal is inputted to a compensating filter 4 through a differentiation circuit 2 and a gate circuit 3, and a ringing compensating signal is obtained as the output of the compensating filter 4, and the pre-compensation of the ringing is executed by subtracting this compensating signal from a signal obtained by delaying the input signal by a delay circuit 8 by an adder subtracter 6. When the pre-compensated signal is inputted to the filter 7 to be compensated, an output signal free from the ringing can be obtained. Thus, the ringing compensation of a circuit difficult in the viewpoint of technique such as a high-power circuit or a high frequency signal part can be easily executed by small power at the preceding stage of high frequency.

Title: Rear-wheel steering controller for all-wheel steering vehicle
Inventor: OHASHI KAORU
IPC: B62D113/00
Filed: 1989-12-21
Abstract: PURPOSE:To keep the running stability of a vehicle so favorably by installing a factor correcting means which corrects a factor so as to check its variation set by a factor decision means when a detected steering speed is largely varied in the decrement direction. CONSTITUTION:In this controller, there is provided with a factor correcting means 6 which corrects a factor so as to check its variation being set by a factor decision means 3 when a detected steering speed of a steering speed detecting means 2 is largely varied in the decrement direction. With this constitution, when each steering speed of front wheels FW is largely varied in the decrement direction, the factor correcting means 6 corrects it so as to check a variation in the factor being set by the factor decision means 3, so that a steered variable of each rear wheel RW in the same phase direction will not be lessened so suddenly. With this constitution, even if the steering speed is temporarily and suddenly decreased, the steered variable of the rear wheels RW in the same phase direction will not be suddenly decreased at all, and since steering control in the same phase direction at the safety side is maintained, the running stability of a vehicle is favorably kept up.

SOLUTION: An organic metal molecule (TEGa), hydride (AsH3 ) and SiI4 gases are fed into a deposition chamber of a chemical beam epitaxial(CBE) system. The organic metal molecules and hydride gases emitted into vacuum react on a heated substrate 2, thus forming a deposition layer of a semiconductor material, that is, GaAs. At the same time, the SiI4 gas is given thermal energy on the surface of the grown substrate and is thermally decomposed. Thus, Si enters as a carrier into the GaAs crystal so that n-type doping is carried out. This technique may also be applied to crystal growth methods, such as, metal organic molecular beam epitaxial (MOMBE) growth, gas source MBE, metal organic chemical vapor deposition (MOCVD), and MBE.

Abstract: PURPOSE:To facilitate exchange of resilient bodies and to improve productivity, by providing an auxiliary plunger pressed by a resilient body at the tip end of a plunger pin. CONSTITUTION:A resilient body 16 inserted in a recess 5c provided at the tip end 5a of a plunger pin pushes an auxiliary plunger 5b upwards. A moulding material 13 is pressed thereby and fed by the plunger pin 5 so that cavities 3 and runners 14 are filled therewith. Since there is variance in weight of the moulding material 13, the amount of the material 13 fed for filling the cavities 3 from a pot 4 differs according to such variance. Such difference in amount of the material 13 causes difference in upward movement of the plunger pin 5 which is represented as difference in pressure exerted on the moulding material. Therefore, the plunger pin 5 is provided with the auxiliary plunger 5b pressed by the resilient body 16 so that the difference in upward movement of the plunger pin is absorbed thereby for eliminating variance in pressure exerted to the molding material.
