Title: Theft prevention device for vehicle
Inventor: NOSE SHINJI
IPC: B60R25/10
Filed: 1990-11-22
Abstract: PURPOSE:To facilitate release by a real owner in a vehicle in which the release operation of a theft alarm is being made by conducting one reciprocation movement of a key cylinder between an accessory position and an ignition position, by arranging so that the operation of OFF ACC intervening between ACC and IG may be ignored. CONSTITUTION:A controller 1 that is on the alert, watches a door switch 6 and a hood switch 7, and when even one of them becomes OFF, it issues an alarm by operating a siren 2 and a lamp 3, and extracts a condition that releases this alarm, from the sequential action of an ACC switch 4 and an IG switch 5. That is, when alarm occurrence is brought in, coming to an ACC position next is awaited, and when the ACC position is brought in, coming to an IG position next is awaited. And when the IG position is decided, ACC is awaited. At this time, an excessively turned OFF is watched while waiting for IG, and when IG is detected in the process, alarm release is made. In contrast to this, when an OFF position is detected, the ACC position is detected, and when ACC is brought in, IG is awaited, and when IG is brought in, the release operation of the whole is made to be effective, and the alarm is released.

Abstract: PURPOSE:To improve the accuracy of control by calibrating the sensitivity of a sensor by using a replenishing liquid the concn. of which is confirmed. CONSTITUTION:The specific component concn. of a medium 2 in a medium tank 1 circulated to the tissue culture system of plants is measured by a glucose sensor 4 which responds to the specific component concn. and is controlled to a prescribed range. The sensor 4 is moved into a sensor holder 3 when the decrease of the concn. below the set concn. is measured by the sensor 4 at this time. The high-concn. replenishing liquid 6 of the glucose which is an additive soln. and the medium 7 without contg. the glucose are successively fed to the sensor by a selector valve 8 and the calibration of the sensor is executed. The position of the sensor 4 is thereafter returned and the measurement is continued. The decrease of the concn. is detected by the sensor 4 and the necessary replenishing amt. is calculated. The calibration of the sensor 4 is executed as well at the time of supplying the replenishing liquid 6. The degradation in the measurement accuracy is, therefore, obtained by properly repeating the calibration and the concn. is maintained at the prescribed value over a long period of time.

Title: Controller for sewing machine
Inventor: KONDOU IKUZOU
IPC: D05B69/18
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To reduce the dispersion of stop position at the time of sewing machine stop by reducing the torque ripple of induced motor without making electromagnetic noise adverse at the time of operating the induced motor. SOLUTION: Concerning a device for controlling the drive of sewing machine by performing PWM(pulse width modulation) control to an inverter for generating an AC driving signal for driving the induced motor, PWM control is performed to the inverter so that the output of inverter can become a prescribed frequency, and the carrier frequencies of PWM signals at the every time of control are respectively set (S10 and S19) so that the cycle of PWM signal in the case of stopping the sewing machine by outputting the fixed PWM signal to the inverter (S17-S20) can be made longer in comparison with the cycle of PWM signal in the case of operating the sewing machine (S11-S16).  As a result, at the time of stopping the sewing machine, the final stop position can be controlled constant while preventing the generation of electromagnetic noises from the induced motor at the time of operating the sewing machine.
