Title: Magneto-optical recording and reproducing device
Inventor: SHIYOUKAWA YOSHIHIKO
IPC: G11B11/10
Filed: 1989-01-26
Abstract: PURPOSE:To prevent the destruction of recording data with a simple constitution by allowing light for reproducing information to be generated after confirming that the direction of the magnetic field of external magnetic field is turned to that in the case of recording information. CONSTITUTION:A signal amplified by a Hall element 34 provided between a disk 3 and a permanent magnet 31 arranged a certain distance away from the disk 3 is amplified by a preamplifier 35 and converted into digital data by an A/D converter 36, then inputted in a CPU part 24'. The CPU 24' controls to read the recording data with emitted light for read after confirming that the magnetic field of the permanent magnet 31 is turned to a recording direction. Thus, in the case of reproducing the information, the destruction of the data caused when the external magnetic field turns to an erasing direction is prevented by confirming that the direction of the magnetic field of the external magnetic field turns to the recording direction. Moreover, the constitution of a control system, etc., for the magnetic field direction is simplified because the operation is sufficient just by turning the direction of the magnetic field to two directions.

Title: Channel changeover during communication
Inventor: SUZUKI SHIGEFUSA
IPC: H04B7/26
Filed: 1992-02-04
Abstract: PURPOSE:To realize a control method by which a channel is switched surely during communication even at a location of zone border where a radio wave cannot suddenly be reached. CONSTITUTION:When a mobile station detects zone movement, the station sends a channel changeover request signal to a base station to which the mobile station moves. A mobile station identification number is included in this signal. An exchange station during communication uses the number to discriminate whether or not the channel changeover takes place in its own station, and makes channel changeover reply to the mobile station via a new base station to which the mobile station moves when the channel changeover is within its own station to make the changeover complete. When the channel changeover device takes place at the outside of its own station, the channel changeover is stopped or the exchange station discriminates it that the mobile station is moving to other exchange station and makes a channel changeover request to a new exchange station.

Title: Injection valve for gaseous fuel
Inventor: KOGA AKINORI
IPC: F23C99/00
Filed: 1979-02-22
Abstract: PURPOSE: To reduce the production of NO x  and to perform a perfect operation of a gas turbine, by a method wherein guide vanes are located at an outlet of a steam passage of a fuel injection valve so that an injected steam will whirl, and a flame- cooling effect is produced resulting from the riftless surrounding of a circulating flame.  
     CONSTITUTION: Guide vanes 14 are located at given intervals on an inner surface of a ring 15, and are secured on a fuel injection valve 1 through the medium of the ring 15. The guide vane 14 is twisted such that a plate, stretching from an inner surface of the ring 15 toward the axis of the ring 15, forms a generatrix which stretches obliquely at a lower end of the ring 15 from the axis of the ring 15 toward a lower front of the ring 15. This format cuases a steam S flowing in from the upper part to flow out such that the steam will whirl in the direction being oblique to the front. The steam S is injected frontward in the injected direction of the fuel injection valve 1 to form a riftless steam film 16 at the front of the injection valve, so formed riftless film isolating a circulating flame 4. Furthermore, the steam film 16, becoming a strong whirling current, can reduce a flame temperature effectively.
