Title: Detection or measuring apparatus for tilting of scanning mirror surface for light-beam deflection
Inventor: MORIZUMI YOSHIAKI
IPC: G02B26/10
Filed: 1985-09-13
Abstract: PURPOSE:To detect or measure positively tilting of a scanning mirror surface in driving condition by allowing a beam of light reflected by a cylindrical surface of a reflecting mirror to be reflected again and leading it to the original source-side light path. CONSTITUTION:Among beams of light reflected and deflected by a scanning mirror 6 only a limited portion of beams in the deflected range is reflected by a cylindrical mirror 10. Now, a pair of photoelectric conversion elements 12 is shifted to a position where the beams of light are available by rotating a threaded shaft 15 with an handle 16 and moving the elements 12 finely in vertical directions and the amount of rotation of the shaft 15 is red out on a scale attached to the handle 16 for measurement of the shifting amount of the element 12. Thus, even if a deviated amount of the point of projection of the beam of light is infinitesimal, remarkably accurate measurement becomes available and condition of a tilting of the scanning mirror surface can be measured at high accuracy.

Title: Urethane coating
Inventor: SHIMA ETSUYA
IPC: B05D7/24
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To manufacture a thick-walled urethane film and smooth its coating work. SOLUTION: A polyol 11 and an isocyanate 12 and fed into a spray gun 15 while being heated separately, sprayed and mixed to form a urethane film on a surface to be coated. At the point of jetting from the spray gun 15, the reaction of the polyol 11 with the isocyanate 12 is started, and in this state, the surface is coated and cured to form a urethane film. The spray state is carried out in an extremely short time, and the coating is not disturbed by the reaction curing of the polyol with the isocyanate. The necessity of using a solvent, therefore, is not generated, and the operation is quite safe and a highly viscous material can be used therein. When viscosity is high, a film can be formed thick, and the caulking operation for cracks can be applied. The hardness of the film can be adjusted by the mixing ratio of the polyol to the isocyanate.

Title: Method for preventing electrostatic charging on electron beam exposure device
Inventor: MIYAGI SHINJI
IPC: H01J37/305
Filed: 1984-09-26
Abstract: PURPOSE:To provide high precision patterning by an electronic beam, by forming a metal film through sputtering on the organic insulating films deposited on a deflecting electrode and a plate for shielding the deflection electrode thereby to remove charging of the surface of the organic insulating film. CONSTITUTION:The electronic beam generated in an electronic beam generator 3 passes on the central axis through a lens system 4, a deflecting plate 5, a plate for preventing deposition of a foreign substance on the deflecting plate, and a secondary electron detecting support 7. In the case that splashes of a resist film are deposited on the plates 5, 6 and the support 7 and are charged up, a metal needle 8 is inserted in the central axis through the plates 5, 6 and the support 7 when removing these deposits. When the plates 5, 6 and the support 7 are connected to each other and a high-frequency voltage 9 is applied between this and the needle 8, a plasma is generated between the two. This plasma causes atoms or molecules of the metal of the needle 8 to sputter and deposit on the surfaces of the resist films over the surfaces of the plates 5, 6 and the support 7. By this, even if the resist-coated surfaces are bombarded by the electron beam, they will not be charged up.

Title: Rectifier
Inventor: KUBOYAMA KEIJI
IPC: H02M7/21
Filed: 1992-07-29
Abstract: PURPOSE:To provide a rectifier which facilitates rectification of a high frequency input signal without depending upon an ambient temperature. CONSTITUTION:When an input signal VINT is smaller than a reference voltage source Vref, a drain current (= source current) is not applied to a MOS transistor TR1. Therefore, the inverse input terminal potential VM of an operational amplifier OP is kept to be the reference voltage (Vref). Only when the input signal VINT exceeds the reference voltage, a potential difference is created between the terminals of a resistor R2 and the voltage VM is higher than the reference voltage (Vref). An output voltage Vout is a half-wave rectified voltage which does not contain parameters depending upon an ambient temperature at all.

Inventor: MATSUZAKI HIROFUMI
IPC: G01B11/02
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To provide the device and method for wire height inspection which can efficiently inspect wire height. SOLUTION: By the wire height inspecting method which picks up an image of a wire 6 by a camera 8 and finds the degree of focusing of the wire 6 in the image by a focusing degree calculating process part 14 to decide whether or not the wire height is acceptable, it is judged whether or not the wire 6 is within the measurable range of a wire height measuring process part from the found degree of focusing. When the wire is within the measurable range, the height of the wire is estimated from the degree of focusing and when not, the focus position of the camera 8 is moved to picks up an image of the wire 6 again after the focus movement. Consequently, wire height inspection can efficiently be performed with high precision by using a high-precision camera which has characteristics of a narrow measurable deviation quantity.
