Title: Ignition device for internal combustion engine
Inventor: IKEUCHI MASAYUKI
IPC: F02P17/00
Filed: 1990-10-02
Abstract: PURPOSE:To make a power supply of a CDI ignition part and a power supply of an ion current detecting part in common so as to obtain an ignition device small in size at a low cost by providing constitution such that the power supply from a power supply part, connected to the CDI ignition part, is given to a detection part for detecting a combustion condition of an internal combustion engine. CONSTITUTION:DC voltage of a CDI power supply 1 is converted into AC voltage in an oscillator 21, and the AC voltage is boosted by a transformer 22, further rectified by a rectifying diode 23 and applied to a capacitor 24 charged. When a thyristor 26 is turned on by a signal from a signal generator 6, a charge of the capacitor 24 is discharged through the thyristor 26 and a primary side of an ignition coil 25, and high voltage is generated in a secondary side of the ignition coil 25 to ignite a spark plug 28. An ion current following combustion of a mixture in an internal combustion engine 5 by this ignition is detected by an ion current detection part 3 and output by an output terminal 7. Power is fed to the ion current detection part 3 from an ion current detecting power supply 4 serving as a power supply part.

Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To correct the rotational position of parts accurately while facilitating automatic selection and rotary operation of a suction nozzle by using the rotation of a turret part for positioning parts at parts handling position through a rotary drive motor. SOLUTION: A mounting head comprises a suction nozzle unit 12 provided with a plurality of kinds of suction nozzles 5a-5c arranged at a constant interval in the circumferential direction. Each suction nozzle unit 12 faces a parts feeding position facing a parts feeding part and a parts mounting part facing a printed board sequentially through intermittent rotation about the rotational axis. Every time when each suction nozzle unit 12 faces the parts feeding position, a suction nozzle 5a-5c corresponding to the type of required electronic parts is moved to a parts handling position. More specifically, the parts are located selectively at a parts handling position by switching the parts handling means, i.e., the suction nozzles 5a-5c, a mechanical chuck, or the like, through rotation of a rotary means at a turret part.

IPC: G03G21/00
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent the release of automatic sticking by feedback control, by regulating the inputting of a driving signal to a motor, when it is judged that the motor being a driving source for a photosensitive drum etc., is being stuck. SOLUTION: Just after power is applied to the body of a copying machine, so-called preceding multirotation control for rotating and warming up a photosensitive drum and a transfer drum is performed. When the preceding multirotation control is set in, whether a vibrating motor does not rotate even if a pulse signal is sent to a motor driver 2 for a predetermined time from a pulse generator and a high-frequency control circuit 3, namely whether or not the vibrating motor 1 is being stuck is judged, on the basis of information from a pulse comparator 5. When it is in a stuck state, pulse signal sending from the pulse generator and the high-frequency control circuit 3 to the motor driver 2 is stopped, and application of a high-frequency voltage to the vibrating motor 1 is regulated.  A signal for regulating the operation of a DC motor for driving a transfer belt is also sent to a control circuit for the DC motor.

Title: Jam detecting method
Inventor: OISHI CHIKASHI
IPC: G03G15/00
Filed: 1987-10-19
Abstract: PURPOSE:To reduce the occupying time of a CPU and efficiently detect jam by judging whether any change takes place in the detecting condition of sensors for each defined time and detecting the occurrence of the jam of an electrophotographic sensitive material. CONSTITUTION:Plural jam detecting switches 61-69 are provided along the conveying passage of a sheet of master paper 4. The ON/OFF conditions of all of the switches 61-69 are detected in a very short time (approx. 5-10musec.) and the detected condition of this time is compared with the stored previous detected condition. As a result, when this time detected condition is different from the previous detected condition, it means that a sheet of master paper is being conveyed, judging to be no jamming. Also, when the detected conditions of both are the same, it means that no sheet of master paper is being conveyed, judging to be the occurrence of jam.

IPC: G02B23/24
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To maintain stable magnification-changing action by improving the efficiency of a linear transmitting member in transmitting a rotary driving force. SOLUTION: In this endoscope, a movable end lens for varying an observing distance is driven by a linear transmitting member 10 and a motor 30 is used to rotate the linear transmitting member 10. A holding member 24 for holding the protective tube 26 of the linear transmitting member 10 is fixed to a chassis 22 by screws 28. A holding member 25 for the motor 30 is rendered movable in the direction of a rotational axis 100 by mounting it to the chassis 22 by means of screws 35 via oblong holes 34 (A-D) provided in right and left extension plates thereof. Thus, the linear transmitting member 10 becomes less likely to rotate while elongated, to prevent an increase or variation in friction between it and the protective tube 26.

Filed: 1985-11-26
Abstract: PURPOSE:To perform measurement with accuracy below one wavelength of laser light by forming interference fringes using the laser light and measuring expansion or contraction of a sample from the quantity of movement of the interference fringes. CONSTITUTION:The laser light from a laser oscillator 1 is splitted into two and one side is reflected on the sample 2 and the other side is reflected on a mirror 10 as the reference surface. As a result, interference beams are generated on a beam splitter 6. The interference fringes are formed on an image sensor 14 by the interference beams. The interference fringes are converted into an electrical signal by the sensor 14 and its driving circuit 15 and supplied to a microcomputer 16. The computer 16 calculates the distance to a light part of the interference fringes closest from the reference position of the sensor 14 and calculates the quantity of expansion or the quantity of contraction from a change of the distance. In this way, the measurement can be performed with the accuracy below one wavelength of the laser light.
