Title: Hand display type electronic watch
Inventor: NISHIMURA KATSUO
IPC: H02P8/40
Filed: 1981-06-23
Abstract: PURPOSE:To provide a hand display type electronic watch which is reduced in power consumption, by a method wherein, corresponding to a counting value obtained by clock circuit after a drive pulse stops, an electromechanical converter is operated by a quick feed to restore a display to a present time. CONSTITUTION:If a crown switch 9 is pulled by one step, a drive circuit 4 stops applying a drive pulse to a step motor 7 of an electromechanical converter through a control and switching circuit 3 and hands of an analogue display mechanism 8 are left as they are brought to a stop. Simultaneously, a clock circuit 6 counts a stop time. If, with this, the switch 9 is depressed to a normal position, a quick feed pulse, corresponding to the counting value of the circuit 6, is applied to the motor 7, the display 8 is restored to a present time. The constitution prevents a drive pulse from being applied to a display motor at a non- use time and enables to perform a rapid and reliable return to a present time at a using time, which results in providing a hand display type electronic watch  consuming no useless power and being reduced in a power consumption.

Abstract: PROBLEM TO BE SOLVED: To oxidize and decompose color substances and hardly decomposable substances in practical wastewater at low cost with lowered energy consumption by adding cultivated white putrefactive bacteria to a reaction tank into which the practical wastewater flows and utilizing the decomposition enzyme produced by the white putrefactive bacteria. SOLUTION: A mixed water MW of raw water OW, which is practical wastewater, and white putrefactive bacteria is stored in a reaction tank R. While becoming fine bubbles, air blown from a blower B is mixed with the mixed water MW by an aeration apparatus S and supplied to the aerobic white putrefactive bacteria. The white putrefactive bacteria in the mixed water MW propagates while decomposing organic matter contained in the raw water OW or a carbon source added from outside, forms flock-like aggregate, and floats in the mixed water in suspended state. The color substances contained in the raw water OW are decomposed and decolored and also hardly decomposable substances are decomposed into smaller molecules by the decomposition enzyme released by the propagated white putrefactive bacteria.

Title: Method for measuring space between ultraviolet ray interference fringes
Inventor: INOUE SUSUMU
IPC: G02B5/18
Filed: 1994-05-11
Abstract: PURPOSE:To measure the space of interference fringes of ultraviolet rays in real time by converting a part of fundamental light to ultraviolet light by applying the fundamental light to a nonlinear optical medium. CONSTITUTION:The wavelength of the fundamental light from argon ion laser light source 11 is 488nm and is included in a visible region. When fundamental light enters a nonlinear optical crystal 12, the second harmonic of the fundamental light is generated. The second harmonic is the ultraviolet ray with a wavelength of 244nm which is half the fundamental light wavelength. The ultraviolet light and the fundamental light advance coaxially and are branched into two part by a beam splitter 31 of an interferometer 30. Then, light reflected by total reflection mirrors 32 and 33 crosses, thus forming the interference fringes of ultraviolet light and fundamental light. Then, the images of the interference fringes consisting of the fundamental light are picked up by a CCD camera 43 via an objective lens 41 and a microscope. Since the space of the ultraviolet interference fringes is half the space of the fundamental light interference fringes, the space of the ultraviolet light interference fringes can be obtained from a camera 43 of the fundamental light interference fringes.

Abstract: PURPOSE:To enable resist elements near the tip of a nozzle to be maintained and the resist film thickness on a substrate to be kept to a constant by mounting a cap which can be mounted and removed at the tip of the nozzle through an O ring. CONSTITUTION:A cap 3 for blocking is provided at the discharge port of a nozzle 2 through an O-ring 4 which is a packing. Normally, when a resist l exists within the nozzle 2, the resist 1 is sackbacked for preventing drop of liquid after coating resist and a boundary surface 5 of the resist 1 is located at the rear. part from the tip. Since a cap 3 is mounted to the tip of the nozzle 2, the space which the boundary surface 5 contacts is sealed and a solvent of resist from the boundary surface 5 is vaporized, thus filling the can. Therefore, the concentration of solvent environment can be maintained to be constant where the amount of solvent vaporized from the boundary surface 5 and that of solvent dissolved into resist from a solvent environment 6 are balanced, thus preventing viscosity of resist at the tip part and rear part of the nozzle from changing.
