Abstract: The present patent application discloses a flash device for camera, or a camera, including a light emitter for flash photography mounted about a pivot shaft on the camera body and a light condenser mounted about a pivot shaft on the photographic lens barrel which moves to vary the light distribution characteristics of the light emitter as the focal length of the photographic optical system varies, wherein when the flash device is in use, the light condenser moves as the focal length of the photographic optical system varies, thus making it possible to obtain the light distribution characteristic which is suited to the focal length of the photographic optical system, while when not in use, the light emitter and the light condenser are turned to be integrally housed in an appropriate plate of either the lens barrel or the camera body.

The disclosed arrangement of the flash device not only ensures an adequate light distributing characteristic in all the vertical and lateral directions but also permits reduction in size of an electronic flash unit.

Abstract: The enclosed electronic flash device for a camera includes a booster circuit connectible to an electrical power source or battery, a high voltage rectifier diode for rectifying the output of the booster circuit, and a storage capacitor. A main power supply switch and an auxiliary power supply switch are connected in series between the negative poles of the power source and capacitor.

A signal terminal is connected to the negative pole of the storage capacitor through other circuit elements and another signal terminal is connected to one contact of the auxiliary power supply switch, which is connected in turn to the negative pole of the storage capacitor. The auxiliary power supply switch is connected in series with the main power supply switch at a point farther from the negative terminal of the battery than the main power supply switch.

Abstract: A flash shot control device for a camera in which the angle of flash lighting is controlled in accordance with the output of a backlight detector. On assumption that a subject of principal photographic interest takes its place at the center of the field of view, when backlight is detected, the flash lighting is concentrated to the central portion of the field of view, thereby the shadows of the subject are lightened by the flash.

Abstract: A hydraulic servo axially biases a rack and pinion steering housing to add an additional amount of steering to the front wheels of a vehicle in response to one of (a) the amount of steering wheel rotation, (b) the rate of steering wheel rotation, or (c) the vehicle yaw rate, to compensate for the effect of cross winds or the like.

Abstract: A hydraulic or pneumatic servo arrangement which is controlled in response to the rotation of the steering wheel is connected to member of a rear suspension in a manner to apply a bias thereto which distorts an elastomeric insulator or insulators forming part of suspension so as to steer the wheel or wheels associated with the member in the same direction as the front wheels are steered.

Abstract: A delay which may take the form of a hydraulic flow restriction (either fixed or variable with a given parameter such as vehicle speed) or a suitable electronic delay circuit, is interposed between a device which outputs a signal indicative of the front wheels being steered and a device which is operatively connected with the rear wheels and which varies the orientation of the rear wheels in a manner to "steer" same in response to the signal to control the yawing of the vehicle.

Abstract: To control the compliance steering of the rear wheels of a vehicle during cornering or the like, a link member of the rear suspension arrangements supporting each of the rear road wheels, is provided with a servo mechansim which can vary the length thereof in a manner which tends to steer the rear wheel associated therewith in the same direction as the front wheels are turned to produce the cornering.

Abstract: The pressure outputs of a power steering control valve are fed either to hydraulic cylinders (or servos) or to chambered elastomeric insulator units to, in the case of the rear wheels, produce a bias which opposes a side force produced during cornering to prevent the rear wheels from undergoing "compliance steering", while in the case of front wheels, induce same to turn through an angle slightly greater than intended by the driver to either prevent compliance steering or increase same to improve vehicle handling when cornering respectively .

Abstract: A flash device of the type in which the flash tube is coated with a trigger electrode and is positioned in contact with the back metal constituting part of the reflector so that when the trigger signal is applied directly to the back metal, the flash tube is triggered. In this type of flash device the back metal constituting part of the reflector is configured to a round shape. Because of the necessity of insuring good light distribution it is generally made of bright alloy aluminum. This not only makes it difficult to finely adjust the position of the flash tube relative to the back metal and electrically connect the trigger wire lead with the back metal, but also gives rise to a problem of electrically insulating the back metal from the other metallic parts since a very high voltage for triggering is applied to the back metal.

Abstract: In the disclosed flash camera, a flash unit is movable between protruding and stowed positions, and a sensor senses whether a capacitor that flashes the unit is adequately charged. A switch and a control circuit enable the flash only when the unit is in the protruding position and the sensor simultaneously senses an adequate charge.

Abstract: A control circuit for an electronic flash device is disclosed. The control circuit is connected to a commutating capacitor and includes a coil connected in parallel to the capacitor and switching means connected in the discharge path of the commutating capacitor to discharge the charge stored on the commutating capacitor after a switching device for stopping flash emission has changed from the conducting state to the non-conducting state.

Abstract: A computer type electronic flash device is disclosed. The flash device has an auxiliary capacitor for producing a bias voltage which is to be superimposed on the charged voltage across the main capacitor upon triggering of the flash tube, and an impedance circuit provided in the discharge path of the auxiliary capacitor to produce an actuating voltage for the light measuring circuit when the auxiliary capacitor produces the above-described bias voltage.

Abstract: An electrical power supply for an electronic flash unit with a main capacitor charged by a current flowing from a direct-current source through an electrical power source switch to the main capacitor is disclosed. The electrical power source has a semi-conductor switch connected in the charge path to the main capacitor and a detector, arranged to detect whether or not an aerial discharge is produced between the contacts of said switch upon opening of the electrical power source switch, and, upon occurrence of a discharge, to produce a signal. The semi-conductor switch is opened in response to the signal to stop charging of the main capacitor immediately.

Abstract: A flash unit is slidable between a retracted position in a camera body and a pop-up position outside the body. A switch enables a flash exposure control in response to movement of the flash unit out of the camera body and disables the exposure control when the flash unit is moved into the camera body. An override switches the switch to the disabling position when the flash unit is moved outside of the body and forms a discharge circuit for the flash main capacitor.

The stap is subjected to sucessive plastical deformations by pulling the strap from the rod members to damp a large force suddenly applied to the strap member.
