Title: Digital pll circuit

IPC: G11B19/06
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To improve stability by generating a clock signal based on an edge interval when the edge interval of input signals is within a prescribed range making a prescribed pulse width a reference to prevent a low frequency component from mixing into a clock signal. SOLUTION: A 1T generating circuit 46 generates the value of 1T by detecting pulse widths 1T, 2T of a BIDATA signal and ignores a pulse width 3T. The value of 1T to be outputted by the circuit 46 is supplied to an adder 48 and a multiplier 50 as the value of an edge interval. In the adder 48, constant-T/2 is added to the value of the interval to be supplied to a low band filter 54. In the filter 54, an abrupt fluctuation component is eliminated from the input to be supplied to an adder 56. In the adder 56, a constant T/2 is added to the input to be supplied from a constant generator 58 to be made to be the value of 1T and then it is supplied to an adder 60. In the adder 60, to a phase error correction value is added the value of 1T from a phase correcting means 50, 68∼74 and the corrected value of 1T is supplied to an NCO 62.  The NCO 62 counts a system clock to be supplied from a terminal 64 and generates a clock rising when the count value becomes 1T.

IPC: B62D7/14
Filed: 1986-05-13
Abstract: PURPOSE:To improve the extent of safety in a way of preventing a steering hydraulic actuator from being suddenly operated at the time of engine starting, by installing a steering operation forbidding device forbidding any actuation of the steering hydraulic actuator. CONSTITUTION:Actuation of a solenoid valve is controlled so as to cause a detection value of a potentiometer R0 detecting a target steering angle theta0 by a handle H to accord with each detection value of potentiometer R1 and R2 detecting an actual steering angle theta, driving both hydraulic cylinders 5F and 5R. And, when an engine, whose stop signal S1 is in an H level, is in stoppage and these angles theta0 and theta are incongruous, a flip-flop 25 is set whereby the output comes to an L level, making a gate G2 come off, and current-energization to the solenoid valve is interrupted, thus each actuation of these hydraulic cylinders 5F and 5R is automatically forbidden.

Filed: 1984-05-30
Abstract: PURPOSE:To realize an extremely stable condition of resting on the floor by providing a caster in a member for said resting and utilizing the caster, in a lowered condition, for moving the furniture and further elevating the caster to bend a flexible plate so as to have the sucking force act on the member for said resting. CONSTITUTION:A seat leg 8 is fitted to the bottom of a cabinet 7. When an operational rod 17, provided in a frame 15 forming the seat leg 8, is operated to lower a vertically mobile shaft 11 which has a screw 15 and is screwed in a bearing member 16, a caster 10 fixed to the lower end of said shaft 11 is projected further downward then the bottom edge of the member 9 for resting on the floor. In other words, the caster 10 is brought in contact with the floor surface 20 and said member 9 is lifted from said surface 20. Accordingly, the cabinet 7 can be easily moved by the caster 10. On the other hand, when the vertically mobile shaft 11 is elevated, simultaneously with resting of the member 9 on the floor, a flexible plate 13 bends upward through a movable member 12. Thus, adsorptive force due to vacuum acts on said member 9, and its stability can be improved.

Filed: 1979-08-29
Abstract: PURPOSE:To prevent the forming of a depletion layer, cancel the stray capacity and improve high frequency characteristics by doping proton or kerypton selectively by ion implantation under the bonding pad or lead wires of a high frequency semiconductor element. CONSTITUTION:In the case of a GaAs.FET, a high resistance buffer layer is formed between a working layer and a substrate, and bonding pads and lead wires are formed on this high resistance buffer layer.

Abstract: PURPOSE:To prevent cracks from being generated at a superconductive layer part even if bending stress is exerted there and to make this wire thin by disposing a core made of super-plastic ceramic inside the superconductive layer part made of an oxide group superconductor. CONSTITUTION:A superconductive wire A is formed of the following parts: a core 1 made of super-plastic ceramic, a superconductive layer part 2 which covers this core 1 and is made of an oxide group superconductor, a coating layer 3, and a stabilized layer 4.
