Abstract: PURPOSE:To prevent defective suction, and to obviate the instability of the accuracy of a film on the top face of a wafer due to heat conduction from a motor by forming the shape of a spin chuck in a blade shape and minimally inhibiting a contacting section with the underside of the wafer. CONSTITUTION:The shape of a spin chuck is formed in a blade shape, and contacting sections brought into contact with the underside of a wafer 5 are arranged at twelve positions in total at four ends. When the wafer 5 is sucked in the spin chuck having a vacuum system, the underside of the spin chuck is brought into contact with the contacting sections 1. Consequently, the wafer is sucked completely by holes 2 for a vacuum and vacuum sections 3, to which the wafer is sucked, and the wafer 5 can be held even when the wafer is turned. The contacting sections 1 with the underside of the wafer 5 are disposed at twelve positions in total, but the number of the contacting sections may be varied into 4n times (n represents an integer) such as four locations, eight locations, etc., in response to the difference of the diameter of the wafer 5. The spin chuck in a multipoint type such as not only e four point type but also a three point type, a five point type, etc., may be used, and the same effect as above-mentioned one is displayed.

Abstract: PURPOSE:To consitute the circuit inexpensively by winding an earth winding overlappingly under a coil of an LC series resonance circuit in the opposite direction to the circuit coil so as to set an attenuation pole at high frequencies freely without increasing number of coils or capacitors and without increased size. CONSTITUTION:The ground winding 10 is wound under the coil 7 of the LC series resonance circuit over 1 turn in the opposite direction to the coil 7.

Title: Recorder
Inventor: SUZUKI YASUTO
IPC: G03G15/04
Filed: 1986-07-14
Abstract: PURPOSE:To make it possible to print on a recording medium an image according to the position of a binding hole, by a system wherein an image printing area on the recording medium is moved in a parallel manner in a predetermined direction relative to the position of the binding hole by a printing-controlling means according to the position of the binding hole detected by a binding hole detecting means. CONSTITUTION:When it is judged by a CPU 21 that image movement is required based on a detection signal 11a sent from a binding hole sensor 11 or for other reason, the CPU 21 writes a moving amount in a scanning direction B into an H offset register 28, and writes a moving amount in a direction (y-axis direction) opposite to a recording paper feeding direction A into a V offset register 29. Under this condition, when a printing position before the image movement is located at, for example, 36, the predetermined moving amounts written in the H offset register 28 and the V offset register 29 are added respectively to x-coordinate and y-coordinate stored in a CAP register 27 to set, for example, a printing position 38 into the CAP register 27, and an image-printing position is moved to the position specified. Thus, the image-printing position can be moved independently in the direction (y-axis direction) opposite to the recording paper feeding direction A and in the scanning direction B.
