Title: Electric charged particle beam working method
Inventor: TAKEMOTO ASAKI
IPC: H01J37/30
Filed: 1979-06-18
Abstract: PURPOSE: To make working by charged particle sure by detecting the actual radiation for the set radiation position and correcting the portion corresponding to the deviation amount thereof.  
     CONSTITUTION: In the charged particle beam working provided with an NC control unit, the carriage 30 placed thereon with the work 14 is placed in the set position and the NC control unit is operated. The reference positions (X 0 , Y 0 ) of X-, Y-tables 9, 4 are set by turning drive machines 10, 6 and detectors 12, 11. Next, to detect whether the actual radiation position coincides with the set position or not, the X-, Y-tables are moved in the positions (X a , X b ) where the electron beam aligns to the reference point 18 of a reference device 15. The deviation from the reference point 18 is finely adjusted by the beam radiation and the deviation amounts (ΔX, ΔY) are obtained. As a result of this, the working position is determined and the X-, Y-tables move to the working position. Thereby, the efficient working operation by beam radiation is accomplished.

Title: Encoding device
Inventor: ARII FUIISERU
IPC: G11B20/12
Filed: 1993-04-02
Abstract: PURPOSE: To obtain a recording and reproducing encoder by making a code word generator position the initial positions of M subgroups at different time intervals εm from the leading edge of a code work and imposing a condition, M>=2 and εm +(I-1)τ<=sτ0. CONSTITUTION: The S, τ0, and sτ0 of an encoded signal Sb respectively represent a positive integer, time interval, and duration. Each signal Sb is formed by superimposing M groups Gm upon another, and the number (m) varies between 1 and M. In each group Gm , the positions tmi of I pieces represent pulse- occupying positions, and the number (m) represents the number of the group Gm , and then, (i) represents a number which varies between 1 and I in the group Gm . In each group Gm , in addition, a first position tm1 is positioned at an interval εm from the leading edge of the signal Sb, and positions tmi are separated from each other at regular intervals τ. When a condition εm +(I-1)τ<sτ0 is imposed to the number I of a position in one group, the code which is used for a recording and reproducing system can be obtained.  The composited signals Sb are evenly distributed in the M groups in a state such that the positions of the same number of the signals Sb per symbol are occupied by pulses and are shifted by a fraction of the period τ.

Abstract: PURPOSE:To avoid any defective bonding process due to misoperation of a contact detector 12 by a method wherein the bonding process is performed using a slide block under elastic load of an energizing means. CONSTITUTION:A controller 2 controls the lifting and lowering operations of a slide block 1 conforming to various data stored in a memory 2b. The block 1 is rapidly lowered from the top dead center H to the position immediately before contact M to be slowly lowered from the position immediately before contact M to the bottom dead center L at specified distant DELTAH low speed. During the lowering operation, a capillary 5 in contact with the bonding surface performs the first bonding process I making use of the elastic load of a spring 6a due to clockwise rotation of a bonding arm 3 caused by the lowering action of the slide block 1. The slide block 1 is lifted rapidly to reach the top dead center H in the second bonding process II. While the slide block 1 is stopped at the top dead center H, an XY table is shifted to locate and electrode 8b at the position immediately below the capillary 5. Likewise the slide block 1 is lifted and lowered to perform the second bonding process II.
