Filed: 1995-01-24
Abstract: PURPOSE: To simplify work by floating a floating scaffolding on a water level in a pool and moving vertically the floating scaffolding on the water level by changing the water level of the pool and inspecting an interior wall of a pressure restraint chamber from the floating scaffolding. CONSTITUTION: A reactor housing vessel 2 is formed with a dry well 2a which houses a reactor pressure vessel 1 and a pressure restraint chamber 2b. Before pool water 2c in the pressure restrain chamber 2b is to be drained, a temporary floating scaffolding 3 is floated on the water level 2f of the pool water 2c. Then, a guide roller 3c is installed inside the pressure restraint chamber 2b so as to restrict the horizontal movement by sandwiching a vent pipe 2d which is vertically equipped, thereby changing the water level of the pool water 2c in the pressure restraint chamber 2b. The water level 21 of the pool water 2c is vertically fluctuated while the floating scaffolding 3 is guided to the vent pipe 2d, thereby changing a working position downward. It is, therefore, possible to clean or inspect the coated parts in the pressure restraint chamber promptly.

Abstract: PURPOSE:To prevent a sheet material from slacking or floating on a transfer drum and to eliminate a local decrease in the density of a transfer image by driving a rotary body so that its peripheral speed is equal to or slower than the moving speed of the sheet material by a sheet material carrying means. CONSTITUTION:The sheet material S is gripped by a gripper 7 in synchronism with specific timing and wound around the transfer drum 9 as the sheet carrying means electrostatically by a pressure roller 8 as the rotary body and its counter electrode. Then the pressure roller 8 is coupled with a rotary driving source and driven in the same direction as the moving direction of the sheet material S so that its peripheral speed is equal to or slower than the peripheral speed of the transfer drum 9. Consequently, an invariably optimum frictional load is placed stably on the sheet material on the rotary body 8 to prevent the sheet material from slacking and eliminate a local decrease in the density of the transfer image; and the shifting of the transfer image due to a position shift of the sheet material on the rotary body is precluded.

Title: Magneto-optical head
Inventor: KATASE YOSHIHIRO
IPC: G11B11/10
Filed: 1987-01-21
Abstract: PURPOSE:To miniaturize the head by adopting a polarized beam splitter comprising a polarized film transmitting P polarized light and reflecting S polarized light and a prism and a transparent flat plate clipping the polized film inbetween for an analyzer so as to decrease the distance to a photodetector. CONSTITUTION:The polarized film 16a of the polarized beam splitter 16 has an action to separate the incident light into the P polarized light 14a being the transmitted light and the S polarized light 14b being the reflected light. The P polarized light 14a transmitting through the polarized film 16a is progressed into the transparent flat plate 16c, reflected totally in the rear flat face, transmitted again through the polarized film 16a and the P polarized light 14a and the S polarized light 14b reflected in the polarized film 16a are separated into a prescribed interval. In arranging the polarized beam splitter 16 in the converged light at the back side of the condenser lens 13, the interval (d) is constant independently of the focus of the condenser lens 13 and the position and refractive of the polarized beam splitter 16. Thus, the distance to the photodetector is decreased and the shape of the transparent flat plate is made simpler than that of the optical member having a tilt reflecting face or the hexagonal prism and the manufacture cost is reduced.
