Filed: 1987-06-04
Abstract: PURPOSE:To produce tritium by detaining a lithium compd. into coating layers of pyrocarbon in a neutron field, breaking the coating layers off the neutron field, and heating said layer to a high temp., thereby releasing the tritium. CONSTITUTION:One or plural layers of the pyrocarbon layers 2, 3 having an extremely low transmittance of the tritium are formed on the outside of the lithium compd. 1. Then, the formed tritium is surely held in the lithium compd. 1 on the inner side of the pyrocarbon layers 2, 4 during the irradiation period and, therefore, the loss of the amt. of formation by external release and the contamination of the external environment are prevented. The tritium is taken out of the neutron field after formation and the pyrocarbon layers 2, 3 are broken or are heated by the high-temp. heater without being broken to release the tritium. The tritium is thereby produced.

Title: Hydraulic pressurized machining device
Inventor: SAKAI MITSUO
IPC: B30B1/32
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To suppress useless delivery from a hydraulic pump and to obtain the machining device with a small power loss by controlling, through an inverter, a motor for driving a hydraulic pump in such a manner that, after the pressure of a hydraulic cylinder reaches a target value, if it exceeds the target value, a signal for setting the speed of the hydraulic cylinder in the counter pressurizing direction is made smaller than in other cases. SOLUTION: With a hydraulic cylinder 5 actuated, a machining tool 7 is made closer to a work 6 at high speed. With the position of the hydraulic cylinder 5 measured by a linear scale 9, if the machining tool 7 approaches the work 6, the number of revolution of a motor 2 is reduced, decelerating the speed of the hydraulic cylinder 5. The machining tool 7 comes into contact with the work 6, increasing the pressurizing force. When the pressurizing force measured by a load cell 8 reaches the 60% of a target pressure, the speed of the hydraulic cylinder 5 is further reduced. With the pressurizing force reaching the target pressure, the motor 2 is minutely advanced or retreated thereafter within the time set by a timer, thereby maintaining the pressurizing force at the target value.

Filed: 1983-07-28
Abstract: PURPOSE:To enable to reduce the quantity of sealed insulating oil and to suppress the temperature rise of a stator by providing a pressure regulating mamber coupled with a frame in a can, and sealing insulating particles around the stator. CONSTITUTION:When insulating oil B around a stator 2 largely expands due to temperature rise, the expansion of the volume is released through the hole of a case 25 into the case 25, and an elastic material in the case 25 is inwardly compressed. Thus, the pressure difference between the interior and the exterior of the can 3 is almost eliminated. Since insulating particles 33 are sealed around the stator 2, the quantity of the oil B can be reduced. The particles 33 dissipate the heat of a coil end to a frame 1.

Abstract: PURPOSE: To obtain plural sheets of copy images of good quality with simple equipment by using a photoconductive photoreceptor comprising fixing toner in image- form on the photosensitive surface as a master plate and repeating the process of evenly charging and evenly exposing this, developing the toner then transferring the toner image.  
     CONSTITUTION: The latent images having been obtained through exposure of a photoconductive photoreceptor 1 with a desired original are toner-developed and are fixed to form toner images 2 and this is used as a mater plate (Fig. a). Next, the master plate is evenly charged (Fig. b), following to which it is evenly exposed to  let the charges of the portions other than the toner 2 disappaer and allow the  charges to remain only on the toner 2 portions being non-conductive, thereby forming latent images (Fig. C). After these are developed with copying toner 3, the toner  images 3 thus obtained are transferred to image receiving paper (Fig. d). By repeating the processes of the above (b) thru (d), copying of plural sheets is performed. There is a need for performing fixing of the abovementioned toner images 2 so  as not to impair the non-image portions of the photoreceptor, for which flush  fixing, fixing by toner solvent gas, etc. are desirable.
