Title: Pickup coil
Inventor: SHIMIZU TAKASHI
IPC: F02P7/067
Filed: 1986-12-03
Abstract: PURPOSE:To increase the electromotive force of a coil by making the distance between the magnet and the coil of the pickup coil longer than the winding width size in the axial direction of the coil and providing the axial center of the coil on the side part from the magnet farther than the axial center of an iron core. CONSTITUTION:The distance between a magnet 130 and an coil 110 is made longer than the winding width in the axial direction of the coil 110, and the axial center of the coil 110 is provided on the side apart from the magnet 130 farther than the axial center of an iron core 120. If this is used to detect the rotating speed o an engine, when the engine is started, a rotor is rotated, and the magnetic field of the magnet 130 is an open magnetic path while lugs provided on the outer periphery are apart from the iron core 120. When the lugs pass the end section of the iron core 120, the magnetic field of the magnet 130 becomes a closed magnetic path. Since the portion of the iron core 120 wound with the coil 110 receives little effect of the leakage magnetic flux from the magnet 130, the magnetic flux quantity is largely changed by changes of this magnetic path, thus the coil 110 generates an electromotive force larger than that of conventional ones, and the performance of a pickup coil 100 is sharply improved.

Abstract: PURPOSE:To execute write and reproduction with high accuracy and stabilization by forming the titled circuit so that a driving signal is outputted, when a spot exists in a recording area, and the driving signal is interrupted, and when the spot exists in an address area. CONSTITUTION:In a servo-circuit 20, when an optical spot exists in the recording area of an optical disk 11, servo-closed loops 7a, 7b are operated, and a correct focus and tracking control are executed. On the other hand, the optical spot exists in an address area, the loops 7a, 7b are opened, and it is obstructed that an impact noise flows into the loop. Also, a state before interruption is held by inertial force by an intrinsic mass system which actuators 6a, 6b have. Accordingly, even when the spot exists in the address area, a satisfactory focus and tracking state are maintained. In such a way, write and reproduction can be executed with high accuracy and stabilization.

Title: Vaporized fuel treating device
Inventor: ITAKURA YUJI
IPC: B60K15/077
Filed: 1999-10-08

Title: High impedance protection circuit
Inventor: NEMOTO MORIO
IPC: H03K19/0175
Filed: 1990-10-25
Abstract: PURPOSE:To realize a function equivalent to a high impedance protection circuit requiring addition of external resistors using low power consumption without adding externally resistor by providing a logic integrated circuit with a built-in high impedance protective circuit. CONSTITUTION:An input signal is connected to the input side of inverter 1 at a first stage, and the output from inverter 1 at the first stage is connected to the input side of inverter 2 at the second stage. The output from inverter 2 at the second stage forms an output signal and is fed back to the input side of inverter 1 at the first stage via resistor 3. By introducing this feedback action, even when the input signal is intended to be a high impedance, since the output from inverter at the second stage is connected to the input to inverter 1 at the first stage, the output level is fed back before the input signal is intended to be a high impedance, and thereafter a loop circuit consisting of inverters 1 and 2 and a resistor 3 holds this level, thereby protecting the occurrence of high impedance.

Title: Radio telephony equipment
Inventor: KOIZUMI FUSAO
IPC: H04W88/02
Filed: 1989-11-07
Abstract: PURPOSE:To prevent production of sound giving a sense of displeasure to the user by using a frequency other than audible frequency so as to apply FSK modulation to a header part of a data. CONSTITUTION:A control circuit 2 at a sender side gives a control signal to an FSK modulation circuit 3 while a header part of a data is outputted at data communication between a master set and a slave set to bring the modulation frequency to a frequency at the outside of audible frequency band. When the header part is included in an output signal from a detection circuit 10 at a receiver side, the header part is FSK-demodulated and fed to the control circuit 12, the control circuit 12 discriminates the data reception state based on the demodulated signal and outputs a muting control signal to a muting circuit 13 to activate the muting. Thus, an unpleasant sound generated in a conventional telephone set at data reception is surely prevented.

Patent JP-H02134592-A (JP)
Title: Optical sensor
Inventor: MASUDA CHIHIRO
IPC: G01J1/02
Filed: 1988-11-15
Abstract: PURPOSE:To extend the life of a sensor and to perform detection at a high speed by providing a light feedback type oscillation circuit stopping oscillation when a light path is blocked by an object between a light emitting element and a photodetector apposed to each other. CONSTITUTION:DC voltage DC is applied to terminals T1-T3 and reference voltage utilizing the forward direction coupling voltage of an LED 1 is passed through a resistor R4 through a resistor R1 to be applied to the positive terminal of an operational amplifier OP1 and an LED 2 is biased in a forward direction to emit light. Bias voltage is applied to a photodiode PO through a resistor R2 and the light signal is received from the LED 2 and the light detection signal generated in a resistor R3 is fed back to the OP1 through a condenser C3 to be amplified by the OP1. In general, if the output signal of an amplifier is positively fed back to input so as to become the same phase in a feedback type circuit, oscillation is continued. The oscillation frequency at this time is determined on the basis of the time constant of a resistor T6 and that of a condenser C4. Therefore, when the LED 2 and the PO are blocked, feedback due to light is eliminated and, therefore, the oscillation is stopped.

Title: Control method for induction motor
Inventor: IWAJI YOSHINAO
IPC: H02P21/34
Filed: 1994-11-24
Abstract: PURPOSE: To make it possible to control position, speed, and torque with accuracy, by superimposing an AC current into an output voltage command value at an inverter, and estimating the amount of magnetic flux from an AC voltage and leakage inductance in windings of a motor. CONSTITUTION: A given amount of magnetic flux (ϕ) is generated in a motor 2 according to a voltage and a current of the motor 2. A core part, where the magnetic flux (ϕ) passes, is saturated with magnetism. Considering a tooth for storing a primary winding similarly, part of the tooth in the same direction of magnetic flux is saturated with magnetism. At the same time, leakage inductance changes under an influence of magnetic saturation at the tooth part. An AC voltage other than a fundamental wave factor is superimposed in a motor voltage. Then, the inductance of the winding is measured from a relation of a current passed through and the AC voltage, while the magnetic flux (ϕ) is calculated from a change in inductance. The output voltage and current of an inverter 1 are controlled according to the estimated magnetic flux (ϕ), and non-interference control between the torque and magnetic flux (ϕ) is carried out in the motor 2.
