Abstract: An image sensing device for a TV camera and method of driving the same is disclosed whereby the effective charge accumulation time in each light-sensing row in the imaging area can be reduced thereby eliminating fuzzy images produced when fast moving objects are picked up. The driving circuit of the imaging device gives the sensor a shutter function of less than 1/60 second and up to 1/2000 second exposure time without changing the structure of the sensor. There is provided a method in which charges accumulated in each row of the light-sensing elements are taken out and discarded at an optional time during an active video period, leaving an effective charge accumulation period of less than 1/60 second.

Abstract: In a fuel injection control system for an internal combustion engine, a basic fuel amount is determined in accordance with detected values of intake air pressure and rotational speed of the engine. The detected value of the intake air pressure is averaged by a predetermined averaging function to infer temperature of air flowing into a cylinder of the engine. The basic fuel amount is corrected by the inferred temperature, more specifically, by the difference between the detected value of the intake air pressure and the averaged value of the same so that undesired change in air-fuel ratio resulting from comparatively slow change in temperature of air flowing into engine cylinder upon acceleration and deceleration of the engine is compensated for.

Abstract: An electronically controlled fuel injection system for an internal combustion engine, the system being of the type which controls fuel injection using the charging and discharging of a capacitor and comprising engine operating parameter sensors, a capacitor, and a control unit for controlling the charging and discharging of the capacitor. The charging of the capacitor is initiated at a timing determined as a function of engine speed and throttle opening angle and the discharging thereof is initiated subsequently to the completion of the charging. The charging time period is determined by engine speed and the discharging current is determined by intake air quantity. A basic fuel injection signal is produced so as to have a pulse duration equal to the discharging time period.

Abstract: A braking system for a motorcycle employing a multipiston fluid cylinder arranged in series to provide stepped braking from a single input to both the front and rear wheels. Additionally, a proportional pressure reduction valve operates to reduce the proportional braking pressure to the rear wheel of the motorcycle above a threshold or break point pressure level. An anti-locking system is employed with the front braking system. This anti-locking mechanism includes a warning buzzer and light simultaneously activated and deactivated with the anti-locking mechanism. A control mechanism including a control rod having stepped surfaces is employed to increase the threshold pressure of the proportional pressure reduction valve. The control mechanism disables the warning buzzer and the anti-locking mechanism and generates a continuous warning light signal.

Abstract: A front wheel suspension assembly for a motorcycle includes parallel telescoping forks of the hydraulic shock absorber type which straddle the wheel and which are inclined in a forward direction. The bending moment imposed on the telescoping parts by this inclination is partly or fully opposed by a counter bending moment imposed by one or more springs positioned rearward of a vertical plane containing the wheel axis and below a bottom bridge joining the front fork tubes. The purpose is to reduce the frictional resistance between telescoping forks in their axial sliding motion. The springs apply the compensating bending moment between the telescoping parts.

Abstract: An improved engine supporting structure for a motorcycle wherein a power unit is constructed integrally of an engine, a crankcase and a transmission case and is subjected to pivotal motions with respect to the frame together with a rear wheel. The engine is so arranged that its main axis of inertia is substanially horizontal, and the engine constituting a part of the power unit is pivotally connected to the lower end of a link which in turn has its upper end pivotally connected to the frame. The link is so arranged that its upper and lower pivots are substantially in a vertical line, and the rear portion of the power unit supporting the rear wheel is connected to the frame through a shock absorber. In this manner, the transmission of engine vibrations to the frame is restricted, the following characteristics of the rear wheel in the longitudinal direction are improved, and the riding quality is improved.

Abstract: An improved vehicular anti-skid brake device in which a brake oil pressure generating device generates brake oil pressure in accordance with a braking operation input. A braking force applying device applies a braking force to wheels in response to the brake oil pressure generated in the brake oil pressure generating device. At the time of braking the wheels, a control device actuates immediately the brake oil pressure generating device so as to restrain generation of the brake oil pressure by the brake oil pressure generating device against the braking operation input when the braking force to the wheels by the braking force applying device is excessive. The anti-skid brake device of the present invention is high in reliability of operation, has a good response in braking sense, can overcome difficulty in mounting and arranging the device on the vehicle, simplifies an oil passage arrangement required for the anti-skid control.

Abstract: Signal charges are accumulated in photosensitive elements of an integrated semiconductor imaging matrix, the charges being divided into two parts. Responsive to first and second pulse signals, the first or preceding part of the charge from each of the elements is drawn out via a charge transfer device, as a non-information signal. The second or following part is drawn out, as an information signal, responsive to transfer pulse signals and shift pulse signals. Therefore, even in the presence of intense light, the information signal charges are stored in the photosensitive elements for only a short period of time between the ending time of the first pulse signal and the beginning time of the transfer pulse signal. Thus, the storage will not overflow the capacity of the photosensitive elements.

The springs apply the compensating bending moment between the telescoping parts, or between the lower telescoping fork parts and the frame of the motorcycle.

Also, the fork assembly is mounted on the frame for pivotal movement about an inclined axis diverging with respect to a plane containing the axes of the telescoping tubes.
