Title: Sorting device
Inventor: KENMOCHI MITSUO
IPC: G03G15/00
Filed: 1983-02-10
Abstract: PURPOSE:To facilitate sorting of documentation by moving an output tray repeatedly in a certain direction by a specific amount for every documentation unit, and thereby easily displacing the position of placing the documentation relatively. CONSTITUTION:After the first sheet of documentation 15A is exhausted to an output tray 4, a motor 5 is rotated either in the regular or reverse direction so as to move the output tray 4 horizontally in the direction perpendicular to the exhaust of sheets by a certain amount for every documentation unit, and then the sheet 15B and 15C are loaded at a certain spacing. Sorting of sheets 15A, 15B and 15C is thus facilitated by dislocating the sheets from each other.

Title: Nuclear power plant
Inventor: SUDO AKIRA
IPC: G21D3/08
Filed: 1988-02-02
Abstract: PURPOSE:To suppress generation of stress corrosion cracking by measuring the electric conductivity of the reactor water of a recirculation system and the concn. of the dissolved oxygen therein before inflow to a reactor coolant cleaning system and controlling the electrical conductivity of the reactor water so as to attain <=0.1mus/cm. CONSTITUTION:The reactor coolant cleaning system 13 is installed by branching the same from the reactor recirculation system 2 and the cleaned reactor water is returned to a reactor pressure vessel 2. The reactor water is sampled from the cleaning system 13 by a sampling line 14 and the electrical conductivity, the concn. of the dissolved oxygen, etc., are analyzed in a sample analyzing rack 15. This rack 15 controls the cleaning system 13 by the measured result of the electrical conductivity of the reactor water and controls the water quality in such a manner that the conductivity of the reactor water does not exceed 0.1mus/cm. Just the control of the conductivity of the reactor water is thus necessitated without requiring hydrogen injection at all or the water can be improved to the quality at which the stress corrosion cracking does not arise with a slight quantity of hydrogen even if the hydrogen injection is needed. The ratio of the increase in radiation doses is thereby suppressed.

Filed: 1985-02-08
Abstract: PURPOSE:To shorten the cycle time in an automatic sticking device for a sheet material for a tire by detecting the distance from the sticking target position to the terminal portion of each sheet material by means of an image sensor. CONSTITUTION:An image sensor 8 is adapted to detect the total distance of a distance l fro a sticking target position S to a reference point A and a distance l1 of the terminal portion of a sheet material W1, that is, the length of the material W1 and the distance l+l2 from the leading end thermal portion of a sheet material W2 to the position S.

Title: Bearing
Inventor: HIRAOKA YUUJI
IPC: F16C33/16
Filed: 1980-02-26
Abstract: PURPOSE: To eliminate the need to supply a lubricant and to enhance the supporting rigidity in a slide bearing by arranging a load receiving surface of a high rigidity and a solid lubricant material surface so as to intersect with the sliding direction alternately.  
     CONSTITUTION: Into each of a plurality of recess grooves 3 formed on the bearing 2 is put a solid lubricant material 4 slidably or with some play. The inner diameter of the solid lubricant material 4 is smaller than the outer diamter of a shaft 1. The solid lubricant material 4 has a cut-off 4a at one place, through which it expands resiliently when engaged around the shaft 1. Thus a contact pressure is produced at the contact surfaces of the solid lubricant material 4 and shaft 1. In this instance, as the load receiving surface of the bearing 2 and solid lubricant material 4 which supplies a lubricant to the load receiving surface are arranged so as to intersect with the sliding director. Therefore, a prominent bearing can be obtained which produces little slide friction without any supply of lubricant and has a high supporting rigidity.

Title: Shift positioning control method for operating body in machine tool and device therefor
Inventor: YANAGISAWA MASAYOSHI
IPC: B23Q17/22
Filed: 1991-02-15
Abstract: PURPOSE:To improve the positioning accuracy of an operating body in a machine tool while enabling low-priced manufacture because of not using a linear scale by performing the shift positioning control of the operating body not on the basis of closed control but on the basis of semi-closed control, and cancelling the elongation of a feed screw caused by temperature rise at the origin setting time of the operating body. CONSTITUTION:A driving motor 9 provided with a position detecting device 7 is driven to rotate a ball screw nut 15 through gears 11, 13 and to move a ball screw 19 interlocked with the ball screw nut 15. At the time of moving a carriage 21 connected to the ball screw 19 in the same direction as the ball screw 19, the origin position of the carriage 21 is detected by the limit switch 49 of an external sensor to perform the origin setting of the carriage 21 periodically. The elongation of the ball screw 19 is thereby cancelled to improve the positioning accuracy of the carriage 21.

Title: Light source device for image reading
Inventor: KOBAYASHI KOICHI
IPC: G03B27/54
Filed: 1988-02-01
Abstract: PURPOSE:To improve the stability of light quantity and orientational distribution by providing projections which create the same space as the inside of a bulb so as to oppose two straight tubers and making the inner diameter of communicating parts smaller than that of the straight tube parts. CONSTITUTION:After an electrodeless discharging lamp is lit up, mercury which has cohered to the air release pipes 7a and 7b evaporates in response to the temperature rise of the inside of the bulb 2. The temperature of the inside of the bulb 2 rises because the diameter of the communicating parts 2c and 2d is smaller than that of the straight tube parts 2a and 2b. If the temperature of either tube 7a is higher than the other tube 7b under some influence, the mercury diffusing in the straight part 2a diffuses surplus mercury through the communicating parts 2c and 2d. I.e., the diffusion and cohesion of mercury vapor in the discharging space of either straight tube part 2a depend on the temperature of the tube 7a, while the diffusion and cohesion of mercury evaporation in the discharging space of the other straight tube 2b depend on the temperature of the tube 7b. This causes stability.

Abstract: PURPOSE:To miniaturize a printer by attaining development with positively or negatively charged toner and a suitable developing bias voltage, with respect to the surface potentials of six levels on a photoreceptor. CONSTITUTION:An exposure in the first and second exposing is set in six levels from a color signal in each picture element. At this time, for instance, a developing machine 107 has negatively charged yellow toner. The developing bias potential of a developing roll in the developing machine 107 is set between the potential levels of V4 and V5 and the yellow toner is stuck only in the potential level of V5. A developing machine 108 has positively charged black toner and the developing bias potential of the developing roll in the developing machine 108 is set between the potential levels of V2 and V4 and black toner is stuck only in the potential level of V2. Consequently, the toner of a desired color is stuck to the picture element of each color, charged to the same polarity by a toner electrifier 109 and transferred onto a paper sheet 113 altogether by a transfer unit 110.
