Title: Uniform irradiation type electron beam optical system
Inventor: SAKAI TOMOAKI
IPC: H01L21/027
Filed: 1981-06-08
Abstract: PURPOSE:To provide an electron gun with high stability, high emission and high luminance and to make it as a source of electrons for use in an electron exposure apparatus by a construction wherein a convex lens is used to form a surface where the distribution of the density of electrons, which have been irradiated from a plurality of electron beam sources arranged in the form of a plane, is made uniform. CONSTITUTION:Each of the field emission type electron guns constituting an electron array plate is extremely small and may be regarded as a dot light source. Lines 11-9, 15-8, 11'-9' and electron beams 12-9, 7-8, 12'-9' are parallel electron beams generated from the same electron gun. Assuming that the effective irradiation angle of each electron gun is identical, electron beams generated from each of the electron guns become parallel with each other after they have passed through a convex lens. Irradiating regions of the electron guns are overlapped on a plane (the position of an aperture plate 4) separated from the convex lens by a focal point f (for instance, 100x). When the range of angles at which electrons transmit the plane (physical) is the same in each position and thereby electron density is uniform irrespective of the position.

Title: Signal transmission device and method
Inventor: TANIGUCHI RYOSUKE
IPC: B06B1/08
Filed: 1994-04-25
Abstract: PURPOSE:To easily retain an electric wave signal and to surely transmit it over a long distance by transmitting the electric wave signal obtaining a large excitation acceleration with a small amplitude due to magnetostriction phenomenon via a rod-shaped body (drill pipe). CONSTITUTION:Information detected by various kinds of detectors 5 provided at a pit bottom is read into a transmitter subsystem 1 via an information communication mechanism 11 and is subjected to shock modulation by a modulation circuit 12. Namely, current with the same rising speed as the response speed of the magnetostriction material of a magnetostriction oscillator 21 mounted on the transmitter subsystem is allowed to flow to the excitation coil winding of the oscillator 21 via a high-speed switching circuit 15 and current is intercepted when magnetic field reaches a target value, thus generating a large acceleration and hence a shock wave. The shock wave becomes a supersonic acoustic signal, is propagated through a drill string connected to a drill pipe 4 and reaches a reception subsystem 6 on the ground, is detected by an acoustic detector, and is demodulated into an original coded data signal. Since the supersonic waves are attenuated less, a signal can be surely transmitted even over a long distance.

IPC: G03B13/00
Filed: 1988-04-11
Abstract: PURPOSE:To automatically eliminate a zero adjustment shift and to execute a servo-control by obtaining correction data of the zero adjustment shift, based on the deviation of a position set value and a position feedback value and bringing the data to subtracting correction from the deviation. CONSTITUTION:The deviation DELTAS of a position set value set by a position setting device 1 and a feedback value obtained from a position feedback value output device 2 is allowed to pass through a dead band means 13, and it is detected to exceeds the reference value of a prescribed zero adjustment shift. Subsequently, DELTAS' allowed to pass through the means 13 is multiplied by the adjustment gain of a zero adjustment shift of an adjustment gain output device 14 by a multiplier 15, and its multiplied value is subtracted from DELTAS by a subtracter 4. As a result, the zero adjustment shift accumulated stably is eliminated and the state that the position feedback value is equal to the position set value can be held. In such a way, the correction of the zero adjustment shift can be performed automatically and continuously and a servo-control is executed with high accuracy.

Title: Marking method
Inventor: SHIMADA HIDEKI
IPC: B23K26/00
Filed: 1992-03-12
Abstract: PURPOSE:To solve the generation of a part where a mark is omitted due to a bridge by using a stencil wherein bridges of patterns are cut at different positions to the mark, and forming the mark while overlapping the patterns when the mark is to be indicated with the use of the laser beam and stencil. CONSTITUTION:To mark an object 60, first, laser beams are oscillated from a laser oscillator 10 to be reflected in the object 60 by a mirror 20. At a first marking, one pattern 42 among a pair of patterns 42 and 43 having bridges cut at different positions in a rotary stencil 40 is used. The rotary stencil 40 is subsequently rotated so that the other pattern 43 comes to the same position as the one pattern 42. A second marking is performed to the same position of the same object 60 with using the other pattern 43. Accordingly, since marking is carried out in the overlapping manner, a part where the mark is omitted due to the bridge of the pattern is never generated.

IPC: G01B11/30
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To detect even a microdefect to be generated on the end face due to insufficient pressure for filling a die with molten resin surely and efficiently at the time of manufacturing a coupling. SOLUTION: When a coupling 20 is supported by a disc-like coupling support 11 with the end face of a receiving port 21 being directed downward, the end face faces a distance sensor 12 disposed below. When a drive motor 15 is driven under that state, a rotator 14 fixed with the distance sensor 12 is moved round along the end face of the receiving port 21. A data processing section makes a decision whether a defect is present on the end face at the receiving port 21 of the coupling 20 based on the distance between the distance sensor 12 and the end face of the coupling 20 being measured over the entire circumference thereof.
