Title: Clock signal generator and method and system for measuring packet transmission time
Inventor: TANAKA TSUTOMU
IPC: G04R40/04
Filed: 1993-12-24
Abstract: PURPOSE:To improve the clocking accuracy of a clock driven by a crystal oscillator. CONSTITUTION:Time data where a GPS receiver 20 outputs the oscillation frequency (the number of clock pulses: wave number) of a crystal oscillator 11 are stored at a count start time register 13 and an end time register 14 and the wave number of clock pulses oscillated by the oscillator 11 is counted by a frequency counter 17 of these start time and end time. The difference between the count value and a target wave number (the wave number when the oscillator 11 oscillated at a rated frequency) which is calculated based on the start time and the end time is calculated and a compensation value so that a compensation value operation part 16 cancels the difference is calculated and is output to a clock 10. Therefore, even if the GPS receiver 20 cannot receive a position-measurement signal constantly (even if time data cannot be output), an accurate time (clock signal) can always be output since the clock 10 is calibrated.

Abstract: PURPOSE:To increase the number of the times when measurement can be made per unit time and to improve the efficiency of measuring operations by providing a resetting accelerating means which accelerates the resetting of a biosensor after the end of the measurement to the state before the measurement. CONSTITUTION:A 2nd constant-temp. water supplying device 19 is connected in addition to a constant-temp. water supplying device 8 to a flow cell 16. The set temp. of the supplying device 8 is set at, for example, about 30 deg.C which is the temp. required at the time of measurement and the set temp. of the supplying device 19 is set at, for example, about 35 deg.C higher than the temp. of the supplying device 8. The constant- temp. water from the supplying device 8 is first supplied and the measurement is made by holding the part of the flow cell 16 and a glucose sensor 1 at about 30 deg.C at the time of the measurement. Flow passages are switched by selectors 20, 21 and the part of the cell 16 and the sensor 1 is held at about 35 deg.C upon ending of the measurement. Further, the flow passages are so switched as to supply the constant-temp. water from the supplying device 8 again when the electrode current restores a base current value. The sensor temp. is increased after the end of the measurement in such a manner and, therefore, the reaction is accelerated and the electrode current is rapidly returned to the base current value.

Title: Disk mass eccentricity detector for disk driving device and disk driving device
Inventor: IIDA MICHIHIKO
IPC: G11B19/20
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To correctly detect a mass eccentricity quantity of a disk even when internal vibrations in a device are small by preparing a current detecting means which detects a current fed to a motor and a means which detects a mass eccentricity quantity of the disk from a current fed to the motor by a current detecting means in plural number of revolutions of the motor. SOLUTION: Servo signals to a spindle motor 3 are generated with a servo circuit 13. A motor current in plural number of revolutions of the spindle motor 3 which is detected with a resistor 15 is fed to an A/D converter 17 after amplifying via a differential amplifier 16 and converted into a digital current value. A mass eccentricity quantity of an optical disk 1 is detected with a CPU 14 into which the digital current value is inputted. The mass eccentricity quantity (ΔI) is obtained from ΔI = (a motor current at the time of high speed rotation) -(a motor current at the time of low speed rotation). When the mass eccentricity quantity is judged to exceed a preliminarily set threshold, the number of revolution of the spindle motor 3 is decreased down to a prescribed number of revolution lower than it by controlling the servo circuit 13 with the CPU 14.

Title: Carrier recovery circuit
Inventor: MINOWA MORIHIKO
IPC: H04L27/00
Filed: 1987-12-26
Abstract: PURPOSE:To perform the recovery of a carrier under a state where a hardware is simplified remarkably by mapping phase information on a memory corresponding to the spatial arrangement of a signal point, and extracting the phase information when a local oscillation frequency is deviated from a carrier frequency from the memory. CONSTITUTION:When deviation exists between the frequency of a carrier signal and that of the output signal of a voltage controlled oscillator 24, it is orthogonally detected at an orthogonal detection circuit 10. And the address area of the memory 32 accessed by a digital in-phase component value and a digital orthogonal component value outputted from analog-digital conversion circuits 30I and 30Q becomes the address area corresponding to either the half area of the spatial arrangement of the signal point from a synchronous incoming signal corresponding to a difference. Thus, the phase information read out from the area, that is, the phase information to eliminate the deviation is supplied to an oscillation controlled voltage generation circuit 50. In such a way, the oscillation controlled voltage of the circuit 50 is moved in a direction to reduce the deviation, and finally, the oscillation frequency becomes the carrier frequency.

Title: Device and method for fuel control of internal combustion engine, and vehicle using the same
Inventor: ASANO SEIJI
IPC: F02D45/00
Filed: 1993-12-27
Abstract: PURPOSE:To extract a target output without amplifying pulsation of intake by computing a mean value based on a measured intake flow rate and sampling values stored before specified times. CONSTITUTION:An intake flow rate measured with a thermal air flow meter (H/W sensor) is input into a block 101. In the block 101 computed is a mean value Qaf(n) based on a sampling value Qa(n) read out in reference to the measured air flow rate and a sampling value Qaf(n-nc) stored nc times before; where nc is a natural number variably set according to an operation condition of an engine. In a block 102, physical delay of the H/W sensor is included in the mean intake flow rate, so that digital filtering treatment is carried out for compensation. In a block 103, an engine speed is calculated from a signal of a crank angle sensor. In a block 104, a reference fuel rate required by the engine is calculated from the intake amount and the engine speed. It is thus possible to vary delay intervals of data line input to a difference formula of a weighted average or a delay compensation filter.
