Abstract: PURPOSE:To avoid damage of resist and contamination by dust and maintain highly accurate flatness by a method wherein a periphery of a wafer is held by a holding member provided in a load chuck and, after rough alignment made by rotation, the wafer is transferred onto a wafer chuck and the flatness is adjusted. CONSTITUTION:When a wafer 1 is brought under a load chuck, an arm 14 is descended. When a pressing force of a cylinder 30 is released, a lever 27 is rotated by a spring 29 with a fulcrum shaft 28 as a center and a periphery of the wafer 1 is held by rollers 20, 25 and a movable roller 26. At this state, a motor 24 is driven and the wafer 1 is rotated to the arrow direction by a driving roller 21 and when the orientation flat touches the roller 20 a repulsion sensor 31 operates to stop the motor 24. The X-direction positioning of the wafer 1 is made by the roller 20 and the Y-direction positioning is made by the roller 25. Then the arm 14 is ascended and rotated and the wafer 1 is transferred onto a wafer chuck and the flatness of the wafer 1 is adjusted by, for instance, operating a piezo element 33.

Patent JP-H0419684-A (JP)
Title: Bias transfer device
Inventor: KOGA SHINJI
IPC: G03G15/16
Filed: 1990-05-14
Abstract: PURPOSE:To prevent the contamination of a transfer body with comparatively simple constitution by impressing the bias potential of a polarity by which a developed image is attracted to a transfer sheet only on a conductive area which abuts on an image forming surface. CONSTITUTION:At a transfer position 2, the conductive area 51 on which the bias potential of a reverse polarity to the electrostatically charged polarity of toner, that means, the bias potential of the polarity by which the toner is attracted is impressed abuts on a toner image on the surface of a photosensitive drum 1, so that the toner image on the surface of the photosensitive drum 1 is attracted to the conductive area 51 side to be transferred to the transfer sheet. Since the bias potential is not impressed on the conductive area 51 which does not contact with the upper half 6 of a core body 4, the toner drops by the gravity when the area 51 is separated from the transfer position 2 and rotates downward even though the toner adheres to the surface of the area 51. Thus, the device is easily miniaturized and simplified and the contamination by the adhesion of the developer particles is prevented.

Title: Magnet catcher fixing structure
Inventor: TSUDA KATSUHIRO
IPC: E05C17/56
Filed: 1995-04-27
Abstract: PURPOSE: To reduce the impact noise when a magnet is attracted to a magnet receiving metal by setting the attraction plane of magnet receiving metal in parallel with the moving direction of magnet. CONSTITUTION: In general, the attraction force of a magnet 7 is strong in the vertical direction but decreases in the parallel direction and the impact power of colliding objects depends on the collision angle. A magnet receiving metal, i.e., a first bent part 8a, is disposed such that the attraction plane, i.e., the lower surface, extends in parallel with the the moving direction of magnet 7. Since the collision angle to the attraction plane of magnet 7 is moderated, impact power is suppressed at the time of attraction and thereby the impact noise can be reduced.

Title: Veideo signal processor
Inventor: ASADA SEIGO
IPC: H04N9/86
Filed: 1986-05-30
Abstract: PURPOSE:To attain the same timing for a luminance signal and a color difference signal even if the phase of a color burst signal is different from that of a synchronizing signal by A/D-converting a synchronizing signal for a chrominance component and a burst signal with the aid of a sample clock synchronizing with the color burst signal. CONSTITUTION:Before the color difference signals R-Y and B-Y are compressed in terms of time base, the sunchronizing signal for color difference signals synchronizing with an input signal the burst signal are fetched by an A/D converter, and data on fetching is added to the color difference signals R-Y and B-Y, after which the color difference signals are compressed in terms of time base. Consequently, even if a compression start point shifts, the relative relation between the color difference signals, the synchronizing signal for the color difference signals and the burst signal never shifts. When the signal is expanded in terms of time base with the synchronizing signal added to the color difference signals and the burst signal as a reference, the hourly delay between the luminance signal and the color difference signals can be eliminated.

Title: Simulation circuit for operation of transformer
Inventor: OOYAMA TOSHIYUKI
IPC: G06G7/62
Filed: 1985-06-12
Abstract: PURPOSE:To change the compensation/transformation ratio of a DC resistance in a 4-terminal circuit by delivering the voltage of the 1st terminal pair to the 2nd terminal pair after amplifying it insulatingly and gain (n) and at the same time delivering the current of the 2nd terminal pair to the 1st terminal pair after amplifying it insulatingly and gain (n) respectively. CONSTITUTION:The voltage V/n is applied to a load through an insulated amplifier 11A and an amplifier 13A (gain 1/n) when the load is connected to the secondary side with the voltage V applied to the primary side respectively. Here if a current I flows to the load, this current is converted into the voltage that is detected by a current detector 15A and applied to a voltage/current converter 16A through an amplifier 14A and an insulated amplifier 12A. The converter 16A functions to supply a current proportional to the output voltage of the amplifier 12A to a terminal at the primary side. This current is equal to I/n since the gain of the amplifier 14A is equal to I/n. The bidirectional properties are required for an ideal transformer and this circuit satisfies these properties.
