Abstract: The present invention is to provide a rear structure of a vehicle body that can ensure high body stiffness and suspension stiffness and that can disperse impact load to the whole body. In the rear structure of a vehicle body, a crossmember 20 bridged between right and left rear side frames 1, 5 is approximately an X-shape in plan view having a first crossmember 21 and a second crossmember 22, and at least one of the front ends of the first and second crossmembers and the rear ends of the first and second crossmembers is directly connected to a structure to be equipped with a suspension.

Abstract: A front structure of a vehicle includes torque box members connecting front side frames and side sills, and front suspension member supports integrally provided on the torque box members. According to the structure of the present invention, the number of members is decreased, and the supporting rigidity of the front suspension member supports is increased. Furthermore, the geometry of the front suspension members supports is maintained by being prevented from local deformation by load application from the suspension member to the front suspension member supports. Thus, the excellent driving stability and maneuverability of the vehicle are assured.

Abstract: In the front frame (1) for a vehicle body formed with a bendable portion (1a) midway thereof, the bending deformation due to a bending moment M1 generated at the bendable portion (1a) of the front frame (1) in case of a vehicle collision is suppressed to improve the effect of absorbing collision energy. A pair of front and rear bead portions (5) arranged in a V shape are formed on the side surface of the bendable portion (1a) of the front frame (1) in such a way that the space between the two opposing bead portions (5) increases gradually from the upper compression side to the lower tension side. Therefore, in case of a vehicle frontal collision, it is possible to generate an additional moment M which can cancel out the bending moment M1 generated at the bendable portion (1a) due to the shape factor of the front frame, so that the deformation mode of the front frame (1) can be changed from the bending mode to a nearly buckling mode.

Abstract: A spindle servo circuit controls the rotation of a disc-driving spindle motor based on absolute address information taken from a disc. Reproduction digital data is written to and read from a RAM. An address control circuit generates a write address of the RAM by counting clocks synchronized with the reproduction digital data by a first counter, and generates a read address of the RAM by counting reference clocks by a second counter. A jitter correction circuit produces jitter-removed reproduction digital data from the RAM. The address control circuit is reset so that the address margin of the RAM is maximized when the spindle servo circuit is locked.

Abstract: A display system for a camera that includes both a segment display portion and a dot matrix display portion. The two different display systems are driven by different duty ratios for assuring clearer presentation and quicker recognition by the photographer. The disclosure also includes an energy-saving control system for such a combination display system where the more energy-consuming dot matrix portion is stopped operating while the less energy-consuming segment portion remains operation after a predetermined time since the last operation of any switch of the camera. The disclosure further includes an elaborate analog display that clearly shows exposure parameters of the camera.

Abstract: A connecting device for establishing electric connection between an electronic appliance and an IC card loaded in position in the electronic appliance, which can prevent possible operation in error and breakdown of a component circuit of the IC card when the IC card is loaded into the electronic appliance. The device includes several terminals provided on the IC card, corresponding terminals provided on the electronic appliance, and a pair of switch terminals located on the electronic appliance for contact with the IC card. The terminals of the IC card and/or the electronic appliance are arranged such that, upon loading of the IC card, at first supply of power to the IC card from the electronic appliance and resetting of the IC card may take place. Signals of the switch terminals which are operated at a last stage eby the IC card are applied to cause activation of the electronic appliance and initialization of the IC card.

Abstract: A power supply system for a camera supplies electrical power to a light measuring circuit, a display circuit and others. During a hold state before the camera turns into a standby state, the power supply system supplies a boosted electrical power intermittently to the light measuring circuit, the display circuit and others, so that photographic information such as shutter speed and aperture value based on the measurement of the light measuring circuit are displayed on a display and power consumption in the hold state can be made small.

Abstract: A camera comprises a main switch, a battery, a battery checking circuit, a display device, a timer and a controller. The camera can be operative by the turn ON of the main switch and can not be operative by the turn OFF of the main switch. The battery supplies an electrical power to circuits in the camera. The battery checking circuit checks a state of the battery. The timer counts a predetermined period of time in response to the turn ON of the main switch. The controller controls the display device based on a result of the battery checking circuit to display the state of the battery during the predetermined period of time and turning off a display of the display device if the state of the battery is better for the camera than a predetermined state after a lapse of the predetermined period of time. Thereby, it is easy to see the other display of the camera in the display device.

Abstract: A circuit for detecting a synchronizing signal comprises a gate circuit to which a reproduced synchronizing signal and a window signal are supplied. A first counter synchronized with an output signal from the gate circuit counts a clock signal formed from the reproduced signal and generates an insertion synchronizing signal. A second counter synchronized with the output signal from the gate circuit counts a fixed clock signal and generates the window signal. The output signal from the gate circuit or the insertion synchronizing signal is made a synchronizing detection signal. The frame synchronizing signal can thus be detected stably and reliably.
