Title: Pll circuit generating clock signal for digital video signal reproduction
Inventor: TOMITA KAZUO
IPC: H03L7/093
Filed: 1989-06-23
Abstract: PURPOSE:To obtain satisfactory frequency follow-up characteristic by providing a means whose gain is changed when tape transport speed reaches a prescribed value in a control signal generation circuit, and providing each said means in forward and reverse transport directions of a tape, respectively. CONSTITUTION:A control voltage VZ changing in proportion to tape speed is supplied to an input terminal 12, and the voltage VZ is set at 0V normally, and at a positive and a negative value in the forward and reverse directions respectively. The voltage VZ is supplied to variable gain means 16 and 18, respectively corresponding to the forward/reverse direction of the transport direction of the tape. Thereby, a nonlinear control signal VA having at least two change points corresponding to the tape speed and tape direction is generated. Therefore, the nonlinear characteristic can be controlled so that an oscillation frequency (f) at the free-running state of a variable frequency oscillator 6 can be provided with linear relation against the transport speed and the transport direction of the tape by setting the nonlinear characteristic of the oscillator 6 itself in a direction to cancel the characteristic.

Title: Keyboard device
Inventor: KAMIMURA NORIZOU
IPC: G10H1/34
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To reduce weight of a hammer arm and to obtain the key touch feeling which is similar to the key touch feeling of an acoustic piano. SOLUTION: The back end section of a key 3 is supported by a key supporting member 20 so that the end section rotates around a virtual fulcrum K located in the back of the key 3. Moreover, the ratio of a distance L1 from a key pushing range A of the key 3 to the fulcrum K, to a distance l1 from an operating point B of a hammer arm 7 against the key 3 to the fulcrum K, is made closer to 1. Thus, the degree of reduction in the moment of inertia which is transmitted from the hammer arm in the key pushing range A of the key 3 becomes less than the moment of inertia in a conventional case, the weight of the arm 7 is made lighter and the key touch feeling which approximates the key touch feeling of an acoustic pian, is obtained even though the weight of the arm 7 is made lighter.

Title: Heat treatment of compound semiconductor
Inventor: SASAYA YUKIHIRO
IPC: C01B25/08
Filed: 1979-12-14
Abstract: PURPOSE:To heat treat effectively the compound semiconductor by a system which incorporates the simplicity of a tube opening method and the high atmospheric controllability and safety of a tube sealing method. CONSTITUTION:A GaAs substrate 15 is covered with a cover 13 by filling an As single unit 16 in a container 12 and aligning a low melting point metal 14 such as Ga or the like in a groove 12a. After gas in the container is substituted, the container is heated. The Ga metal 14 is molten at approx. 30 deg.C, and the body is thus bonded to the cover. When the body is subsequently heated to heat treatment temperature, As pressure is increased due to the As isolated from the unit 16, but the As is not isolated from the substrate 15, and the substrate 15 is heat treated. If the amount of volatile element 14 is selectively set, the partial pressure can be sufficiently raised higher than the decomposing pressur of the compound semiconductor 15, thereby sufficiently preventing the isolation thereof from the surface. When it is eventually removed out of a reaction tube and the cover 13 is removed, the substrate 15 can be simply exhausted, and the container can be used again for the heat treatment.

Filed: 1978-12-28
Abstract: PURPOSE: To reduce a surging pressure by forming the valve seat of relief valve into a differential piston type and advancing the timing of poppet action.  
     CONSTITUTION: If electric current of a prearranged value is applied to a proportional electromagnet, a solenoid suction force acts on armature 17 and movable valve seat body 5 and poppet 13 are displaced to the left, compressing springs 14, 12. The movable valve seat body 5 and poppet 13 stop where the solenoid suction force and the power generated on the both springs 12, 14 are balanced. When the pressure of fluid circuit connected to the primary port 9 sharply climbs due to delay factors such as friction resistance on the circumferential surface of movable valve seat body 5, the fluid resistance of passage 8, etc., poppet 13 leaves the seat part 11 during a comparatively lower pressure transition and subsequently, movable valve seat body 5 pursues the poppet 13 at a speed to meet resistance. Therefore, the relief action is begun at a comparatively lower pressure.

Title: Ink feeder for ink jet plotter
Inventor: FURUKAWA TATSUYA
IPC: B41J2/20
Filed: 1978-12-25
Abstract: PURPOSE:To prevent ink dripping by sucking ink during the down time with a simple device by means of a liquid chamber in which the internal pressure is changed depending on the existence of the flow provided in the ink passage and an elastic member provided on the wall surface of the chamber. CONSTITUTION:When a pump 2 is driven to change over a three-way valve 4 to the head 5, a constant flow of ink moves in the passage 16. The Venturi effect causes the pressure in a liquid chamber 18 to lower and the elastic member 20 is pulled inward, thereby reducing the real capacity of the liquid chamber 18. As the ink flow vanishes, the capacity in the liquid chamber 18 increases. In this manner, the ink on the head side is sucked corresponding to the increment of the capacity thereby eliminating ink dripping during the down time.
