Abstract: PURPOSE:To increase exposure sensitivity and to obtain a good regenerative signal corresponding to an exposure pattern by a method wherein a dielectric layer and a light sensitive layer are provided between a pair of electrodes having a predetermined electric potential and the light sentive layer is formed of a substance having high X-ray absorption efficiency. CONSTITUTION:Composition is made by providing a dielectric layer 4, lead oxide layer 9 having high X-ray absorption efficiency, and selenium light sensitive layer 5 serving as a photo conductor between a pair of electrodes 2, 3 applied a voltage by a power supply 1. More optical carriers are generated in the lead oxide layer by aiming X rays from the transparent electrode side and positive charges are attracted to the negative electrode 3 side and phased out by combining with negative charging charges. Meanwhile, negative charges are attracted to the positive electrode 2 side and stopped travelling by the layer 4 and becomes charge distribution corresponding to an exposed image by opposing to the charging charges of the positive electrode 2. An exposure pattern is recognized by reading the displacement current. In this way, a good regenerative signal with superior exposure sensitivity can be obtained.

Further, when the trailing end of the paper sheet 12 passes by a microswitch 18 which therefore, turns on a solenoid 19, a follower roller 14b approaches the low speed drive roller 14a, and therefore, the trailing end of the paper sheet is clamped between the rollers 14 while the speed of the paper sheet is lowered to the peripheral speed of the low speed drive roller 14a. Accordingly, the rear end part of the paper sheet 12 is moderately stored into the intermediate tray 5, and then is positioned to the front end position of the intermediate tray 5 which is inclined, without passing over due to inertia, thereby it is possible to refeed the paper sheet by means of a half moon-like roller 21.

Filed: 1989-06-30
Abstract: PURPOSE:To prevent a power device of an inverter from damaging due to an abnormal overheat by detecting the temperature of the device, and lowering or stopping the output of the inverter if the detected voltage is a predetermined temperature or higher. CONSTITUTION:If the temperature of an arranging part of a thermistor 33 becomes high, the electric resistance of the thermistor 33 gradually increases, and an input voltage (c) to a comparator 31 also rises. If the input voltage C exceeds V0, the input voltage (c) to the comparator 31 is inverted from negative to positive. The comparator 31 is turned OFF by the inversion, and the output (d) of the comparator 31 is opened. When the output (d) of the comparator 31 is opened, the input voltage (e) of a comparator 32 is inverted from negative to positive by VH. The comparator 32 is turned ON by the inversion, and the output voltage (f) of the comparator 32 becomes VL. Thus, a control voltage (z) also becomes VL, and a motor 11 is stopped.

IPC: H01J37/28
Filed: 1992-06-03
Abstract: PURPOSE:To provide a scanning electron microscope suitable to observation of a sample such as an insulator. CONSTITUTION:When a sample irradiation current indicated by an exciting current indicator 11 is changed, the voltage to be applied to a control electrode 85 by a control voltage generator 13 based on the control signal from a control circuit 10, is changed, while the voltage to be applied to a scintillator 82 by a power source 9 based on the control signal from the control circuit 10 is changed. The surface of a sample 6 is charged positive or negative by the irradiation of primary electron beams, while the intensity of an electric field 81 is maintained at an optimum level corresponding to the current value of the irradiation/electron beams by the control through the control circuit 10. Appropriate secondary electron can thus be emitted from the sample without charging. An image free of charge-up can thus be observed.

IPC: C25D17/00
Filed: 1981-10-20
Abstract: PURPOSE: To prevent sticking of plating metal on roller surfaces and to perform stable plating work by forming the outside circumferential surfaces of guide rollers for a belt-like sheet to corrosion resistant and conductive specular surfaces and supplying washing liquid to the contact parts of the rollers and the sheet.  
     CONSTITUTION: A belt-like sheet 1 affixed with conductive foils on both surfaces and applied with piercing is sandwiched with a pair of guide rollers 7 and is passed through the inside of a plating cell 2, whereby it is plated. Hard chrome plating is applied on the outside circumferential surfaces of a pair of the guide rollers 7 which guide the transfer of the sheet 1 and feed electricity thereto, whereby corrosion resistance and conductivity are given thereto, and the surfaces are finished to specular surfaces. Washing liquid 9 such as water or dilute sulfuric acid is blown through nozzles 8 to the contact parts of the rollers 7 and the sheet 1. Thereby, the sticking of the plating metal on the roller 7 surfaces is made difficult, and the stuck metal is washed off easily, thus the evolution of heat between the rollers 7 and the sheet 1 is suppressed.

Title: Sector opening/closing device
Inventor: KOBAYASHI KOICHI
IPC: G03B7/097
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To shorten a closing time when the diameter of an aperture is large by a sector device opened/closed by the forward and backward rotations of a stepping motor. SOLUTION: The rotation of the stepping motor 14 is transmitted to sectors 12 and 13 through a connecting gear 15. The aperture AP is opened when the stepping motor 14 is rotated forward and closed when the stepping motor 14 is rotated backward. The connecting gear 15 for transmitting the rotation of the motor to the sectors 12 and 13 is energized toward an initial stage position by a spring 16 and rotated while charging the spring 16, at the time of executing an opening operation. Therefore, as the aperture diameter is made larger, the charging power level of the spring 16 is made higher as well. When the pulse time width of a backward rotational pulse is reduced at the time of rotating the stepping motor backward, a sector closing speed is increased but a motor power level is decreased.  However, in this case, the decrease of the motor power level is supplemented with the increase of the charging power level of the spring 16, so that even if the time width of the backward rotational pulse is reduced, the motor can rapidly execute driving for closing, without stepping out.

Title: Optical cable type heat sensor
Inventor: SUETSUGU YOSHIYUKI
IPC: G08B17/06
Filed: 1988-07-08
Abstract: PURPOSE:To identify a heat detected place with a simple arrangement by using the local microbending loss of a covered optical fiber caused by the contraction of a press-winding tape composed of a thermo-contracting material. CONSTITUTION:Covered optical fibers 12 are twisted together around a center tensile strength wire 11 having protrusions 11a on its surface, a press-winding tape 13 composed of the thermo-contracting material is wound on the fibers 12, and a metallic conduit 14 having high heat conductivity is applied as a housing. Consequently, when the ambient temperature becomes high, and heat is transmitted to the press-winding tape 13, the press-winding tape 13 contracts in its longitudinal direction, the covered optical fibers 12 are pressed against the protrusions and meander, and optical transmission loss by microbending increases. Thus, time of day and the place where the ambient temperature rises can be accurately detected by continuously monitoring the longitudinal directional optical transmission loss distribution of the covered optical fibers 12 by a back scattering light measuring instrument.

Abstract: PURPOSE: To catch the fine particles contained in muddy water and to well control the concentration of said water, by controlling the concentration of the water by using a deposited filter-bed layer formed on the upper side of the layer and sending compressed air into the muck-containing muddy water.  
     CONSTITUTION: Compressed air is introduced into a tank 16 through a pipe 26 when a blade wheel 30 is rotated. When remained soil consisting of fine particles is deposited in a space 39, it forms a filter-bed layer 41, and fine particles contained in muddy water are filtered by the layer 41 so that the quantity of the particles is controlled. Accordingly, the concentration of muddy water after the filtration is always kept almost constant by presetting the thickness of the layer 41 i.e. the height of the space 39 properly. Then, the muck-containing muddy water introduced into the tank 16, is separated into the mucks to be dicharged through a pipe 38 and the muddy water to be discharged through a pipe 42 and to be reused.
