Title: Jitter eliminating method for decoder using digital delay line
Inventor: KOITSUME YOSHITAKA
IPC: H03K5/19
Filed: 1987-06-12
Abstract: PURPOSE:To completely eliminate a jitter of one clock portion which a decoder using a digital delay line has originally, by providing a decoding and correcting circuit for shaping an input pulse to a prescribed width pulse and a monostable multivibrator. CONSTITUTION:An input double pulse A which is applied to a count start signal generating circuit 11 outputs a signal F to a monostable multivibrator 15 through a counter 12 and a matrix circuit 13. As a result, the vibrator 15 is driven, generates a pulse H which is shaped so as to eliminate completely a jitter from the decoding range and sends it out as one input of an AND circuit 14. Also, the input double pulse A is inputted to a decoding and correcting circuit 16, shaped to a pulse I of prescribed width, which rises in the center of a decoding range S of the pulse H by the circuit 16, and sent out as the other input of the circuit 14. In such a way, an output pulse K of the circuit 14 becomes a desired decoding signal from which a jitter component has been eliminated completely, that is, a signal which eliminates a jitter of a 1-clock portion which a decoder using a digital delay line has originally.

Title: Control device for induction motor
Inventor: KUDOU TOSHIAKI
IPC: H02P23/16
Filed: 1979-11-12
Abstract: PURPOSE:To simplify the construction of an induction motor and to reduce the regulating labor thereof by forming different set constants by the induction motor to be controlled, with analog element and forming the vector calculator which has been complicated, with digital elements. CONSTITUTION:Primary current amplitude calculating circuit and primary current phase calculating circuit for calculating the phase of the primary current vector in a vector controller are formed of digital elements, and constants (such as, slip angular velocity, constants for induction motor) set in the control circuit according to the type of the induction motor to be controlled, magnetic flux control circuit 10, magnetic flux calculating circuit 15, etc. are formed of analog elements. Thus, the digital elements have almost no control section and produce accurate vector calculation and can eliminate the conventional drawbacks such that pulsating output torque of the induction motor is introduced due to the strain of the primary current command value contained in the error of the analog calculating circuit. Further, the analog circuit such as magnetic flux control circuit can be readily varied in constants and adjustments.

IPC: B41J2/18
Filed: 1979-11-14
Abstract: PURPOSE:To provide a compact feeder eliminating any feed tank by mounting an ink cartridge directly to a subtank having a cartridge receptacle on the top thereof. CONSTITUTION:An ink cartridge 13 is forced into a cartridge receptacle 18 provided on the top of a subtank body 17 and a cartridge cap 15 is pushed up with a thrust bar 16 against a spring 14.

Title: Drive circuit for dc axial flow fan motor
Inventor: UYAMA YASUHIRO
IPC: H02P6/20
Filed: 1988-06-14
Abstract: PURPOSE:To easily switch to high or low rotational speed using a single power source voltage and to effectively start a fan motor at the time of low rotational speed by providing a circuit for controlling the conduction of the phase of one side of 2-phase driving windings. CONSTITUTION:When a control terminal S is in an open state, a motor is normally operated in 2 phases. When a control terminal S is short-circuited to a ground terminal G, a transistor Tr3 is interrupted, and the motor is one-phase- driven to be conducted only at the driving winding L2. When a power source voltage VCC is temporarily turned OFF and again turned ON, a transistor Tr4 is temporarily conducted, and the transistor Tr3 is conducted during that period. Thus, the motor is temporarily operated in two phases to be effectively started.

Title: Optical pickup access controller
Inventor: MASE MASARU
IPC: G11B19/20
Filed: 1995-06-14
Abstract: PURPOSE: To shorten the access time by so variable pitch controlling that the total access time of an optical pickup becomes minimum in the optical pickup access control of a CD-ROM driver. CONSTITUTION: When data is requested from a host computer 8, a main control unit 1 recognizes the address of a present spot by an address reader 7. Rough seeking time calculating means 2 calculates the rough seeking time to the address of the requested data. Spindle accelerating or decelerating time calculating means 3 calculates the accelerating or decelerating time of a motor for obtaining the rotating speed to a target address, and compares it with the rough seeking time. If the rough seeking time is shorter than or equal to the motor accelerating time, the motor is variable pitch controlled to the maximum pitch amount. If the rough seeking time is longer than the motor accelerating time at the maximum pitch amount, the control of shortening the buffering time of the motor is conducted, and made equal by optimum variable pitch calculating means 4.

Abstract: PURPOSE:To obtain a sharp, high-contrast image by providing a 1st electrode on an insulating substrate, a ferroelectric layer on the 1st electrode, and a 2nd electrode on the ferroelectric layer. CONSTITUTION:The film thickness dF of 1st and 2nd electrodes 13 and 15 is smaller than intervals (x), (y) and (z) between the 1st and 2nd electrodes 13 and 14 parallel to the insulating substrate 12. Therefore, when a voltage is applied between the 1st and 2nd electrodes 13 and 15 to invert the self- polarization of the ferroelectric layer 14 sandwiched between both electrodes 13 and 15, the voltage is so set that the polarization in the dF direction of the short distance between both electrodes 13 and 15 is inverted and not inverted in the (x), (y), and (z) directions. Thus, the dF, (x), (y), (z), and voltage are set then only a beta area operates as an active layer and the self-polarization of the ferroelectric layer 14 in the (x), (y), and (z) directions is not inverted. Consequently, the sharp, high-contrast image is obtained.

Abstract: PURPOSE: To make it possible to show the excellence from the viewpoint of energy resources and the global environment and desalt seawater at the same time because of its higher safety, high total thermal efficiency and no emission of carbon dioxide from all circuits. CONSTITUTION: An intermediate heat exchanger 9 separates a primary circuit including a reactor from a secondary circuit including a heat exchanger for supplying the heat capacity needed for a turbine system and a seawater desalting device in order not to leak any radioactive substances in the atmosphere. A heat exchanger of a helical-tube type is used in the intermediate heat exchanger 9. Moreover, the temperature of helium at the exit of the reactor is set at 950 deg.C and that at the entrance at 450 deg.C rather than a conventionally proposed temperature, 400 deg.C.  In this case, in order to secure the integrity of the reactor according to the rise in the temperature at the entrance, the temperature of a pressure vessel is lowered by installing an inner heat-insulating layer with a metal corrugated sheet structure inside the reactor vessel to separate the thermal boundary and the pressure boundary.
