摘要:
This invention has as its object to provide an image forming apparatus in which the number of beam detectors is decreased and which is low in cost and high in the accuracy of the registration position of an image of each color as well as high in quality. To this end, The image forming apparatus is provided with a plurality of image bearing members, an optical system having a plurality of light emitting elements suitable for generating light beams for scanning the image bearing members, a single polygon mirror suitable for deflecting the light beams generated from the plurality of light emitting elements onto the image bearing members, and a beam detector corresponding to at least one of the plurality of image bearing members, and for receiving the light beams scanned by the polygon mirror and producing a first synchronizing signal for recording an image on the relevant image bearing member, a storing portion suitable for storing therein information regarding the error of each side of the polygon mirror, and a producing unit suitable for producing a second synchronizing signal for recording an image on the image bearing member not provided with the beam detector, by delaying the first synchronizing signal outputted from the beam detector, on the basis of the value of the storing portion.

A front pillar of a vehicle includes an inner panel and a garnish panel that covers the inner panel. An air bag is located between the inner panel and the garnish panel. A shock absorber is located adjacent to the air bag and is located between the inner panel and the garnish panel. The shock absorber is fixed to the pillar frame and is separated from the garnish panel. When a primary collision of the vehicle occurs, a secondary collision between a passenger and the front pillar is prevented by the air bag. Even if the passenger directly hits the front pillar, the shock absorber reduces shock accompanying the secondary collision.

A shock absorber is accommodated in a space defined between an inner panel and a garnish panel of a vehicle to absorb secondary collision between the vehicle and a passenger. The shock absorber includes a hollow main body and a projection that protrudes outward or inward. When receiving shock by a passenger occupying a driver's seat, the shock absorber is deformed to fold the projection. When receiving shock by a passenger occupying a passenger seat that is located next to the driver's seat, the shock absorber is deformed to unfold the projection.

A motor control device capable of obtaining necessary and sufficient torque produced by a motor irrespective of the rotation speed of the motor and capable of preventing overcurrent from being applied to the motor. Pulses having a predetermined pulse width are generated in the period inversely proportional to the number of revolutions of the motor. A current control signal is made effective in a time period during which the pulses are generated, while being made ineffective to use a predetermined reference signal instead in the remaining time period. The current control signal corresponds to current to be supplied to the motor so as to obtain the necessary torque. The predetermined reference signal corresponds to current less than the current corresponding to the current control signal. The ratio of a time period during which the current control signal is made effective is increased at the time of rotation at high speed, while the ratio of a time period during which the reference signal is used is increased at the time of rotation at low speed. Therefore, sufficient current to obtain the necessary torque is supplied to the motor at the time of rotation at high speed. On the other hand, the overcurrent can be prevented from being applied to the motor at the time of rotation at low speed.

A semiconductor memory device equipped with a write-per-bit function includes a data-in circuit, a write-per-bit decision circuit, and a write buffer circuit. The data-in circuit and the write-per-bit decision circuit are connected to the write buffer circuit through a single common signal bus line, whereby an output signal from the data-in circuit and an output signal from the write-per-bit decision circuit are supplied to the write buffer circuit through the single signal line. The chip size as well as the number of signal lines can be reduced through such common use of the single signal line.

A suturing instrument for surgical operations is operated by an operator with his one hand. A suturing operation is carried out on a human part to be sutured up by crossing a needle thread and a shuttle thread in a lock stitching formation, the instrument being composed of independent members which are, for use, connected to each other easily, exactly and speedily. The main body of the instrument carrying a needle and a shuttle has an externally operated actuating member which actuates a signal generator incorporated in a connecting arrangement for connecting the main body with the drive part of the instrument, whereby when the drive part is connected to the main body by the connecting arrangement an operator may, by moving the actuating member, activate the drive through the signal generator and set all the parts of the instrument into operating positions.

A curved needle for use in medical operations includes a grip to be mounted in a suturing machine and a curved portion terminated with a needle eye for receivinga needle. On the outside of the curved portion an elongated groove is formed for guiding a thread toward the needle eye. The groove includes a partially closed portion for preventing the thread from slipping out from the groove.
