Title: Scanning interference electron microscope
Inventor: YAJIMA YUSUKE
IPC: H01J37/26
Filed: 1993-05-19
Abstract: PURPOSE:To regulate the phase difference between a probe beam and a reference beam as desired, and to improve the accuracy and the sensitivity of the observation of magnetic field distribution, by controlling the magnetic flux amount in a magnetic path provided between both beams. CONSTITUTION:The electron beams 1 are divided into the probe beams 4 and the reference beams 5 by a biprism which consists of a fine wire 2 and an earthed electrode 3, after being accelerated. To the fine wire 2 which consists of a high permeability material, a voltage is applied in a magnetic closed circuit 13, so as to give a potential difference to the earthed electrode 3. Furthermore, the closed circuit 13 is arranged to cover one side of both beams 4 and 5, and its circulating magnetic flux amount is regulated by controlling the current amount fed to a coil 14 wound on a part of the closed circuit 13 by a current control device 15. When the amount of the circulating magnetic flux is less than the saturation limit of the fine wire 2, no influence is given to the routes of both beams 4 and 5, and the phase difference between both beams 4 and 5 can be converted by converting the amount of the circulating magnetic flux in the fine wire 2. Consequently, the accuracy and the sensitivity of the observation of magnetic field distribution are improved.

Filed: 1989-05-10
Abstract: PURPOSE:To exfoliate the uppermost one of stacked wafers certainly in the direction perpendicular to the surface of the stack by vacuum attracting the uppermost wafer to a spherical wafer attracting surface formed on the pad body. CONSTITUTION:A pad body 1 is placed on wafers W stacked. At this time, the bottom of a vacuum seal 5 contacts the oversurface of the uppermost wafer W to cause formation of a space, which is bounded by it W and the wafer attracting surface 1a of the pad body. At the wafer attracting surface 1a of the pad body 1, thereafter, the uppermost wafer W is warped by the attraction force of a vacuum pump 4 along the spherical surface of the attracting surface 1a, and a gap is produced between this wafer W and the second one W, which admits intrusion of air from the outside circumference. Then the pad body 1 is lifted while the uppermost wafer W is kept attracted. This accomplishes separation of the wafer W without causing damages.

Abstract: PURPOSE:To shorten the access time of an optical disk device by forming a plane vertical and symmetrical to the optical axis at the light input side of an objective lens and forming the light output side into a wedge prism form respectively. CONSTITUTION:A light source 1 is provided so that the light beam is made incident on an objective lens 2 vertically to the light incident on the lens 2 which reads the information recorded on an optical disk. The lens 2 is formed into a plane 2a at the side of the source 1 to avoid dispersion of the light beam of the source 1. While the part of the lens 2 opposite to the source 1 is formed into wedge prism shapes 2b and 2c so that the light beam of the source 1 made incident on the lens 2 is divided into two parts. The 2-split sensors 3a and 3b are set vertical to the light beam of the source 1 in order to receive those two divided light beams. Thus it is possible to detect the degree of deviation of the lens 2 from the increase or decrease of the outputs of the detection signals of both sensors 3a and 3b as well as the deviated direction of the lens 2 and the differential output of a differential amplifier 5.

Filed: 1978-09-21
Abstract: PURPOSE: To provide two cycles of suction-exhaust motion during a turn without a control valve, by fitting two symmetric sectorial rotors eccentric to a revolving body through connecting rods for transmitting the revolution.  
     CONSTITUTION: As a revolving body 10 is turned through an eccentric shaft 9, projected pins 25, 26 move within slots 30, 31 and the movement is transmitted through arms 11, 12 to horizontal and cylindrical rotary shafts 7, 8 which in turn rotate symmetric sectorial rotors 5, 6 fixed to the said respective shafts. The revolution of the rotors 5, 6 makes their ends 5', 6' separated from each other to increase the capacity of a suction chamber 32. The centrifugal force of the rotors then decreases the pressure to take in slurry from a suction port 1 and transfer it through a control chamber 32" to a discharge chamber 32' while turning. As the ends 5', 6' come closer to each other, the pressure increases to forcibly discharge it from a discharge port 2. This system can pump up and out even heavy impurities.

Abstract: PURPOSE:To improve the terminal-side interface while testing the convenience for use of a user-side terminal equipment by performing conversations between a computer and the user in the menu system for syntax generation. CONSTITUTION:A given grammar is defined as G(P,S,VN,VT), and a non-terminal symbol VN is divided into an explicit non-terminal symbol VEN and an implicit non-terminal symbol VIN. The explicit non-terminal symbol VEN can be expressed in a guide menu but the implicit non-terminal symbol VIN cannot be expressed there. The non-terminal symbol VN is VENUVIN where VENVIN is phi, and the part of a product set is empty, and the grammar G becomes G(P,S,VENUVIN,Vr), but the implicit non-terminal symbol VIN is not expressed. The number of stages of symbol in a grammar G'(P,S,VEN,Vr) is smaller than that in the grammar G(P,S,VENUVIN,Vr). Consequently, the number of guide steps is reduced if the grammar G is guided by the grammar G'.
