    Abstract: A magnetic recording system includes an intermediate layer arranged between adjacent ones of a plurality of magnetic layers constituting a magnetic recording medium, the magnetic recording medium driven by a drive section in the recording direction, and a magnetic head including a write section and a read-back section set in relative motion with respect to the magnetic recording medium. Signals are applied to the magnetic head and the output signals from the magnetic head are read back by a read/write signal processing device. The read-back section of the magnetic head includes a magnetoresistive magnetic head. The magnetic layers of the magnetic recording medium include crystal grains having different crystal orientations and existing in overlapped positions in the direction perpendicular to the medium surface. High-density information read/write operation thus is made possible with an improved reliability.

    Abstract: In a system for setting the aperture in a camera for flash photography, a minimum aperture is computed in response to parameters such as distance to an object, stroboscopic guide number and film sensitivity. In one embodiment, a predetermined aperture value is preestablished in the system and the computed minimum aperture is compared therewith. Where the computed minimum aperture is below such predetermined aperture value, such computed minimum aperture is used in flash photography. On the other hand, when the computed minimum aperture is above such predetermined aperture value, an aperture larger than the predetermined minimum aperture value is used in flash photography. Other embodiments for flash aperture setting are also set forth.

    Abstract: A flash device for a photographic camera either inhibits a flashing action or shifts the control mode of the camera from flash photography to daylight photography in cases where the object to be photographed is located outside of an adequately operable distance range. A pre-flashing action detects a distance to the object when a main capacitor is charged to a given level before the capacitor is fully charged for flash photography. Then flash photography is performed at an aperture value determined on the basis of the detected distance when the distance is within the adequately operable distance range. When the detected distance is outside of the adequately operable distance range, the main capacitor is further charged for an increased flashing power. Then the distance to the object is again detected by a second preflashing action before flash photography is carried out at an aperture value determined on the basis of the distance detected by the second pre-flashing action. The flash photography arrangement thus permits seizing a shutter chance for flash photographing an object located at a relatively short distance without waiting until the main capacitor is fully charged.

    Abstract: An image transcribing system for transferring an image from an original document to a recording sheet in which the original image is scanned, converted to binary signals and stored in a first page memory. An image processing section transfers the image data from the first page memory to a second page memory while it is simultaneously enlarged by a predetermined factor. In the enlargement process, the image data is first enlarged by an integer factor then reduced by a fractional factor in accordance with stored bit patterns corresponding to the required fractional factor.

    Abstract: A speed command voltage is generated which increases in proportion to the lapse of time so as to increase the speed of an elevator car at a constant acceleration after starting. Another speed command voltage is generated which decreases with the reduction in the distance between the position of the travelling elevator car and the target floor position so as to decrease the speed of the elevator car at a constant deceleration. The speed patterns provided by these speed command voltages are joined together to provide a continuous speed pattern for the elevator car instructed to travel to arrive at the target floor. In order to ensure shock-free operation of the elevator car at the joint between these speed command voltages, the speed command voltages in accordance with respective speed patterns for use in acceleration and deceleration are compared with each other, and the increase in the speed command voltage for acceleration is ceased when the difference therebetween attains a predetermined value. The speed command voltage is maintained constant at this level to provide a constant-speed command voltage. Then, the constant-speed command voltage and speed command voltage for deceleration are applied to a lower-level signal passing circuit, in which two input signals are compared with each other and the lower level signal of them only is passed, to obtain a completely continuous speed pattern for the elevator car. A reference command voltage is generated, which increases up to a predetermined level with the increase in the speed command voltage for acceleration, and the rate of increase of which decreases gradually upon attainment of such a level. This reference command voltage is used to maintain always constant the length of time of this constant-speed command voltage. The increase in the speed command voltage for acceleration is ceased to obtain the constant-speed command voltage when the difference between the speed command voltage for acceleration and the speed command voltage for deceleration is reduced to a value less than that of the reference command voltage.
