Title: Screw conveyer
Inventor: WATANABE SHINKICHI
IPC: B65G33/26
Filed: 1982-01-27
Abstract: PURPOSE:To obtain smooth discharge of stuff to be conveyed with no remainders in a trough by installing a raking plate which meets at right angles with  the direction of rotation of a rotary shaft, at the outlet part of the rotary shaft. CONSTITUTION:In a screw conveyer, in which a rotary shaft 20 around which screw-shaped vane 19 is wound is placed in a trough 21, and stuff 13' to be conveyed which is comulated on the bottom of the trough 21, is pushed forward by rotation of the vane 19 and then discharged from an outlet port 9 made in a trough side wall which meets at right angles with the conveying direction of the stuff 13', a raking plate 22 which meets at right angles with the direction of rotation of the shaft 20 is installed at the outlet part of the rotary shaft 20. In other words, forcibly raking the stuff 13' which has been conveyed by a screw 8 in the axial direction, toward the outlet port 9 of the trough side wall can prevent the stuff 13' from being packed. Accordingly, the stuff 13' such as nuts which are pushed toward an abutting part 7a of a screw conveyer room 7, can be discharged smoothly without being packed as remainders.

Title: Method for monitoring subcriticalness of nuclear reactor
Inventor: UEDA KIYOSHI
IPC: G21C17/06
Filed: 1990-01-19
Abstract: PURPOSE:To exactly detect the subcriticalness of the reactor regardless of the presence or absence of an artificial neutron source and to assure the critical safety by determining the ratio of the neutron count rates before and after a reactivity change operation is made with plural neutron detectors. CONSTITUTION:The ratios between the neutron count rate before the reactivity change operation is made and the neutron count rates after the reactivity change operation is made are determined with the neutron detectors provided in plural detecting positions at the time of monitoring the subcriticalness of the reactor at the reactivity change operation to generate the reactivity change in the reactor under shutdown. The subcriticalness of the reactor is then monitored by the ratios of the neutron count rates and the fluctuation state of the neutron count rates between the respective neutron detectors. The signals of the neutron detectors are used and the characteristics that the change in the signals depends on the change in the neutron multiplication factor of the reactor core are utilized and, therefore, the subcriticalness is monitored with the high accuracy simply by disposing the neutron detectors for plural neutron regions in the reactor core or on the outer periphery thereof in such a manner regardless of the presence or absence of the artificial neutron source.

Title: Image output device
Inventor: KAWAI NOBUYUKI
IPC: H04N1/40
Filed: 1992-01-24
Abstract: PURPOSE:To simplify the correction of the gradation correction data in response to the change of specifications of an output means by correcting the correction data with the down load carried out in terms of software. CONSTITUTION:A display control circuit 12 controls the address of a video RAM 11 and reads out the image data in a dot sequential way. These image data are sent to an A/D converter LSI 14 and then inputted to a pallet RAM 13 which serves as a gradation correction RAM for the image data. The RAM 13 stores previously the color conversion data multiplied by a gamma coefficient in response to the color expression gradation of a CRT 16 serving as an output means. Therefore the RAM 13 outputs the image data that undergone the color conversion, i.e., the gamma correction. When the CRT 16 is changed to another device type, the contents of the RAM 13 are changed in response to the gradation color expression of the changed device type. That is, a CPU has an access to a data register 14b, for example, and the data multiplied by the gamma coefficient are rewritten by the data corresponding to the color expression.
