Title: Shut-off valve
Inventor: YAMANAKA SHIYUUJI
IPC: F16K3/12
Filed: 1986-10-29
Abstract: PURPOSE:To prevent an inner diameter recess in a seat surface of a valve element from running on the outer diameter section of a valve seat ring in a primary flow passage during the valve element descending, by forming a flat part in the inner diameter part of the valve seat surface in one and the same plane as that of the seat surface of the valve element. CONSTITUTION:A valve element 40 has a valve seat surface on the outer diameter part thereof, and has also a valve seat surface 41 in the inner diameter part thereof in one and the same plane as that of the former valve seat surface. On the way of a descent of the valve element 40 in order to close the valve, guide is effected between a flat part and the valve seat surface of a valve seat ring 2 in a primary passage. With this arrangement, it is possible to prevent an inner diameter recess in the valve seat surface 41 from running on the outer diameter part of the valve seat ring 2 in the primary passage when the valve element 40 descends. Further, the inclination alpha1 with respect to the axis A orthogonal to the passage may be reduced, thereby it is possible to reduce the entrance of the outer diameter part of the lower section of the valve 40 in to the inner diameter part of the valve seat ring 2 in a secondary passage.

Title: Multiple volume hologram element
Inventor: MORINAKA AKIRA
IPC: G03H1/02
Filed: 1989-10-04
Abstract: PURPOSE:To decrease the interference and interaction with other holograms and to improve reproduction efficiency by forming the multiple hologram element to a polygonal columnar or circular cylindrical shape and forming the central part of a recording medium of a material having a low recording sensitivity. CONSTITUTION:The multiple hologram element is formed in the polygonal columnar or circular cylindrical shape. Parts 15 where the recording sensitivity is high and the parts 16 where the recording sensitivity is low are formed within the volume of the recording medium 14. Parts 17 where interference fringes by the multiple recording of the holograms overlap are not generated in the central part as the central part of the hologram is formed as the low-sensitivity part in such a manner. The noises at the time of the reproduction of the holograms are thus decreased and the generation of the faults in recording and reproducing is prevented. The independent recording parts 18, 19 are wide and the volume of the medium 14 can be effectively utilized in the case of the execution of the multiple hologram recording. Since the parts are spacially separated, the output of a high resolution is obtd. at the time of the reproduction and the reproduction efficiency is improved.

Title: Bus network priority control system
Inventor: MATSUMURA HISASHI
Filed: 1986-10-31
Abstract: PURPOSE:To obtain a quick response by dividing data terminal stations into priority stations and non-priority stations and giving the transmission right only to the priority stations for a prescribed time after any terminal station sends a data. CONSTITUTION:The reception control section 8 of a priority station 4 sends a data received from a transmission/reception circuit 5 to a transmission line usage detection circuit 6 and a data reception section 9. In detecting the end of use of the transmission line by other station, the transmission line usage detection circuit 6 sends a data sending permission signal to the circuit 5. The non-priority stations are constituted similarly, but the transmission line usage detection circuit sends a data transmission unable signal to the transmission/ reception circuit for a prescribed time when the end of use of the transmission line is detected. Thus, the priority station 4 uses the line for a prescribed time with priority after the transmission of other station is finished and the transmis sion delay time is limited to a low value even in a high traffic.

Title: Method and device for surface treatment
Inventor: ONO TETSUO
IPC: H01L21/302
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce damages to a gate oxide film connected to a pattern from electron shading by turning off a high-frequency power source which impresses a high-frequency voltage upon a sample prior to the electrified voltage of the pattern reaches the dielectric breakdown voltage of the gate oxide film, and turning on the voltage after the electrified voltage of the pattern becomes sufficiently lower. SOLUTION: A sample 107 is set up on a sample stage 108. In order to accelerate ions incident on the sample 107, a high-frequency power source 109, which impresses a high-frequency voltage upon the sample 107, is connected to the sample stage 108. The breakdown of a gate oxide film is prevented by preventing the rising of a pattern voltage Vp, by turning off the power source 109 before the voltage Vp exceeds the dielectric breakdown voltage Vb of the gate oxide film. When the power source 109 is turned off, the pattern voltage Vp drops, because the ions are no longer accelerated.  When the power source 109 is repeatedly turned on and off in such a way that the source 109 is turned on, when the pattern voltage Vp becomes sufficiently low and turned off before the pattern voltage Vp exceeds the breakdown voltage Vb, the charge amount flowing into the gate oxide film can be maintained at a small amount. Therefore, the dielectric breakdown of the gate oxide film can be prevented.

Title: Motor control system
Inventor: YAMAZOE MASARU
IPC: H02P1/52
Filed: 1985-11-20
Abstract: PURPOSE:To unnecessitate the synchronization device by operating the speed command value by the supply voltage frequency as well as the phase difference between the supply voltage and the motor voltage. CONSTITUTION:In case a motor 11 is accelerated up to the source frequency, the speed command value is controlled as the synchronous speed, i.e. the source rated frequency. When the speed detection value is detected that it comes close to the speed command value, the control device is changed into the speed regulation control. The speed command value in this speed regulation control is operated in the speed command operation element 22. That is; the speed detected value is corrected so as to reduce the phase difference with the source frequency detected value by the phase difference between the supply voltage and the motor voltage, and the value after corrected is used as the speed command value in the speed regulation control. A control device 12 outputs the synchronization command to each breaker 5-9 at the time when a predetermined time passed after the start of the speed regulation control.
