    摘要: A master-slave flip-flop circuiting having transistors connected in cascade in two stages between a power supply and ground. A clock differential amplifier, a master flip-flop, a slave flip-flop, and a waveform-shaping amplifier are all connected mutually in parallel to a power supply. High-speed operation at a minimum operation power supply voltage is achieved.

    摘要: Disclosed is a database management control system based on the client/server architecture including a client process operating on a client machine and a server process operating on a server machine, which prevents resources from remaining allocated without being properly relinquished. When a client makes a request for connection to the server, a starting order identifier notifying device notifies the server process of a starting order identifier indicating the starting order of an operating system on which the client process operates. An executing entity search device of the server process searches for executing entities under control of an executing entity control device, which are correlated to the same network address as a network address of the client machine on which the client process operates. From the executing entities searched out, a starting order identifier comparing device selects executing entities correlated to a starting order identifier older than the starting order identifier notified, and a recovery device terminates these executing entities and recovers or relinquishes resources allocated thereto. This makes it possible to recover resources remaining uselessly unavailable, when the client machine, the power of which was once turned off, is started again and the client process thereof makes a request for connection to the server process.

    摘要: A method of assembling a magnetic head in which a block of wear-resistant material is placed in an indentation at an upper corner of one or more core holders, over which the recording tape is to slide. Grooves are formed on lateral faces of the core holder and the wear-resistant material into which cores and shield plates are inserted. Then two core holders are abutted, with a gap between the so formed lateral faces.

    摘要: A metering light is projected onto an object to be photographed, and the reflection from the object with illumination of the metering light is analyzed to derive an electrical signal in accordance with which the focusing position of a photographic lens is adjusted. When the reflection is found to include a radiation resulting from foreign illumination which is harmonic with the pulsating frequency rate of the metering light, the output of the metering light source is modulated to a random pulsating form.
