Title: Retaining device of plate-like body
Inventor: TOKISUE HIROMITSU
IPC: H01L21/68
Filed: 1987-11-30
Abstract: PURPOSE:To enable positive and stable handling to be made by suspension- supporting a retention unit which has the fluid discharge part and fluid suction part and holds a plate-like body in non-contact so that it may rotate freely. CONSTITUTION:Three retention units 3 are laid at equal gaps on a retention panel 2 for holding a semiconductor wafer 1. The retention units 3 have a lower surface 3A which protrudes from the bottom surface of the retention panel 2. There is a fluid discharge part 31 at the center of a unit 3 to enable pressurized fluid to flow between the wafer 1 and a gap 4 and a circular fluid suction part 32 which suctions fluid and maintains average pressure within the gap 4 at the outside. The retention unit 3 keeps the gap 4 to be constant and retains the wafer 1 to be in non-contact. Since the retention panel 2 is suspension-supported to an installation part 11 by a spherical surface bearing 10, balance can be retained even if the positioning accuracy of the retention panel 2 is poor for the wafer 1 or the wafer stage is slanted.

Abstract: PURPOSE:To improve processing speed by reading information from a shift register, converting it into serial/parallel form, outputting a multiplexed multi- frame synchronizing signal, generating the next state information and writing the result in a shift register while applying parallel/serial conversion. CONSTITUTION:The present status information or the like is read serially + or -at a high speed in preceding over one time slot from a shift register 1 and expanded into a parallel signal by a serial/parallel conversion circuit 2.

Filed: 1987-12-01
Abstract: PURPOSE:To realize the pulse width modulation of an inputted signal with a desired pulse cycle by executing the equivalent modulation when the inputted signal is modulated with a second reference signal. CONSTITUTION:The cycle of the second reference signal of which cycle or shape is different from that of a first reference signal is indicated by an indication means and the signal level of the inputted signal is converted based on a conversion timing signal and the indicated cycle.

Abstract: PURPOSE:To improve dielectric strength without enlarging the size of the width of a tank and to make it possible to provide the compact configuration. CONSTITUTION:A plurality of insulating barriers 9 are arranged between the side wall of a tank 6 and a winding 2 so as to form oil gaps. The side wall facing the central part of the winding 2 in the height direction is expanded in a bow shape. In this static induction electric apparatus, the number of the insulating barriers 9c, which are arranged between the side wall of the tank 6 facing the side of the central part of the winding 2 in the height direction and the winding 2, is made less than the number of the insulating barriers 9a and 9b, which are arranged between the side wall of the tank 6 facing the sides of the upper and lower end parts of the winding 2 and the winding 2. Thus, the insulating barriers 9 are divided at the upper and lower parts and arranged.
