Abstract: PURPOSE:To prevent dusts entering from the outside of a pressurization chamber by arranging a reticle on which a circuit pattern is drawn in a reticle pressurization chamber composed of a reticle case and first projection lens case, and supplying gas thereto at all times. CONSTITUTION:A condensor lens 13 in a light source part is retained by a retaining member 130 and a reticle is placed on a reticle cover 2' and held by a reticle holding member 21, which is moved in the optical axis direction along a guide member 24. The movement is carried out by an exclusive movement mechanism, and a member 24 is fixed to a substrate 25. For the reticle 2, a reticle pressurizing chamber 1 is formed of first and second reticle cases 22, 23 and a first projection lens case 30. To the chamber 1 a pressure supplier 6 is connected through pipes 60, 62. Since the chamber 1 is moved in the optical axis direction, a gap is set, and clean air streams A, B flows to the outside from the chamber 1, as the pressure in the chamber is higher than the outside. With this arrangement, entering of dusts in the chamber can be prevented.

Abstract: PURPOSE:To achieve a stable motion in a compact structure by arranging a nearly hourglass-shaped roller along the circumferential direction of a shaft in a state of being tilted to an axial center of the shaft, and holding the roller between an outer circumferential surface of the shaft and a curved and projecting load rolling surface of an outer cylindrical member by means of line contact. CONSTITUTION:A roller 2 comes into contact with a load rolling surface 31 of an outer cylindrical member 3 and a shaft outer circumferential surface 11 in a state of being tilted as far as a specified angle theta with the axial center of a shaft 1, and when the shaft 1 or the outer cylindrical member 3 is rotated, it rolls on the shaft outer circumferential surface 11 as describing a spiral locus so far as this outer circumferential surface 11, while in regard to the load rolling surface 31, it rolls along the circumferential direction. The roller 2 is formed into a nearly hourglass-shaped one smaller in a diameter of an axial central part 21 than that of a double end part 22, and the outer circumferential surface is formed into a curved and recessed surface along the axial direction. The load rolling surface 31 of the outer cylindrical member 3 is formed into a curved and projecting surface conformed to the curved and recessed surface of the roller 2. Thus, since contact length between the roller 2 and the shaft 1 is sufficiently produced, axial propulsive force of the outer cylindrical member 3 utilizing frictional force is well improved in this way.

Title: Hardware simulator
Inventor: OKADA KATSUHIKO
IPC: G06F19/00
Filed: 1993-12-27
Abstract: PURPOSE:To simulate a large-capacity model at a high speed. CONSTITUTION:The ignition time is added to an event occurring in the simulation and they are stored in an event storage memory part 1. A next time holding part 2 holds the time when the stored event ignites and which is closest to the present simulation Lime. An igniting event taking-out part 3 takes out the event which ignites at the held simulation time. An operation execution part 4 takes out operation information of the taken-out event and peforms the operation. AD event occurrence determining part 5 determines whether the operation result of the operation unit should be propagated to the connection destination or not. When the occurrence of the event is determined by the event occurrence determining part 5, an event generating part 6 generates the event where the ignition time is added to the operation result of the operation execution part 4. An event storing part 7 stores the generated event in an event storage memory part 1 and reports the occurrence time of the event to the next time holding part 2.

IPC: G11B7/09
Filed: 1990-11-29
Abstract: PURPOSE:To prevent a lowering of S/N of the read signal by detecting the offset amount from the output of 1st, 2nd bisected detectors and detecting a tracking error signal based on the output of one side and the offset amount. CONSTITUTION:A light receiving face of error detector 18 made quadripartite to the faces A, D larger than a beam diameter and the faces B, C smaller than the beam diameter. The tracking error signal TEB=B-C is inputted to the inversion input terminal of an operational amplifier 10 through a buffer amplifier 12, and the offset difference between the tracking error signal TEA =(A+B)-(C+D) and the signal TEB is outputted to the inversion input terminal side of an operational amplifier 11 by the operational amplifier 10. Then, the tracking error signal TE in which the offset is corrected, is outputted by the operational amplifier 11 in such a manner that the difference is subtracted from the signal TEB. Thus, the tracking error signal TE in which the offset is corrected, is obtained by using all of the reflected beams from a disk, therefore, the lowering of S/N of the read signal can be prevented.
