IPC: G11B20/02
Filed: 1991-08-08
Abstract: PURPOSE:To attain momentary pattern changeover without causing unpleasant noise by storing a reproduction field video signal into two memories alternately and reading the signal alternately in a prescribed timing. CONSTITUTION:In the case of implementing reproduction of a field picture of any one field in two field memories 4, 5 from the state of frame picture reproduction, even when the frame picture is switched into a field picture, since line interpolation is implemented in the field picture, a change in an output video image is not noticed. Then the video image of one field to be reproduced next is written in the one idle field memory and the output video image is momentarily switched by switching a selector 6. The remaining field video image reproduced next is written in the other field memory and the frame picture is reproduced by switching the selector 6 for each field. Thus, the changeover between the frame picture and the field picture is implemented momentarily by the memory capacity by one frame.

Title: Linear motor
Inventor: AOYAMA HIROSHI
IPC: H02K41/02
Filed: 1995-08-04
Abstract: PURPOSE: To suppress temperature increase of a multi-phase coil and to avoid the reduction in thrust by sealing the multi-phase coil to a coil supporting member which propagates head and consists of a non-magnetic ceramic. CONSTITUTION: A multi-phase coil 2 is fixed to a heat conducting and electrically insulating nonmagnetic ceramic coil support member 4c, for example, the compound sintered body of AIN and BN (thermal conductivity: 75W/mk, electrical resistivity: 2.6×10<12> Ωcm). Since the coil support member 4 has a high thermal conductivity, the heat generated from the multi-phase coil 2 due to drive current is efficiently propagated to the coil support member 4. Also, this coil support member 4 has a high electrical resistivity and generates less eddy current when the coil support member 4 crosses magnetic flux due to the relative move with a permanent magnet 1 for field, thus suppressing the temperature increase of the multi-phase coil 2 and at the same time avoiding the reduction in thrust.

Title: Projection aligner
Inventor: YAMASHITA HIROMI
IPC: H01L21/30
Filed: 1992-07-27
Abstract: PURPOSE:To avoid a bending of an exposure mask due to its dead weight by constituting the equipment with an airtight chamber which makes its inside hollow part airtight when the exposure mask is mounted on it and by controlling an electromagnetic valve so that the pressure inside the airtight chamber may generate a constant differential pressure to the atmospheric pressure. CONSTITUTION:An exposure mask 1 is mounted on an airtight chamber 3 which is closed at the lower part by a thick highly pressure resistant transparent plate 2. At that time, the outer part of the exposure mask 1 is secured by vacuum suction. A differential pressure between the pressure inside the airtight chamber 3 and the pressure above the exposure mask 1 is detected by a pressure sensor 7 and the detected pressure is at all times transmitted to a pressure controller 8. The pressure controller 8 controls the pressure by sending a keying signal to a solenoid valve 9a connected to an air pressure source or a solenoid valve 9b connected to a vacuum source so that the differential pressure may be the one to be balanced with a distributed load due to a dead weight of the exposure mask 1. By this method, the distributed load due to the dead weight of the exposure mask 1 is offset and thereby the exposure mask 1 can keep a flat face with no bending.
