Abstract: PURPOSE:To reduce stress concentration generated at a portion of a through hole of a leaf spring when the leaf spring is deflected, and operate a printing head at a high speed by a method wherein the through hole, which is provided in the leaf spring and through which a bar-like spring is penetrated, is formed into an elliptical shape in the printing head for a dot impact type printer. CONSTITUTION:In a spring charge type printing head, one end of a leaf spring 1 is securely held between magnetic induction bodies 2, 4, and the other end of the leaf spring 1 is coupled to one end of an armature 7, while the other end of the armature 7 is coupled to a terminal end of an arm 8 having a printing pin 9 at the top end thereof. A round hole 7b is formed in the stepped surface 7a of the armature 7, which is provided at the rear part of a juncture with the leaf spring 1, and a bar-like spring 10 is securely inserted into said hole 7b. The bar-like spring 10 is inserted in a through hole 11 formed in the leaf spring 1. In this case, the through hole 11 is formed into an elliptical shape having its major axis in the extending direction of the leaf spring 1, thereby reducing stress concentration directing toward the portion of the through hole 11 of the leaf spring 1.

IPC: H04Q7/36
Filed: 1982-10-20
Abstract: PURPOSE:To increase economically the number of talking circuits, by installing plural directional antennas at a radio station and allotting a circuit to each section of antenna direction. CONSTITUTION:In case the number of radio frequency circuits is increased owing to a traffic increment, etc. at a service zone of a radio station BS1, the directional antennas are set at zones A and B of the station BS1 without installing a new radio station. The different radio frequencies are set between directions of zones A and B of each directional antenna, and at the same time the repeating line between the station BS1 and a mobile exchange station MTSO is controlled as if it were between different radio stations. Then it is supposed that a traveling object MB moves to zone A from zone B under a busy move via an antenna B, for example. Then the station MTSO measures the electric field intensity sent from each radio station, and it is decided that the object MB is moving to zone A from zone B. Then the circuit is switched to a radio talking circuit via an antenna A.

Title: Defective work inspection method for bath device
Inventor: IKEUCHI YASUHIDE
IPC: F24H1/00
Filed: 1991-06-26
Abstract: PURPOSE:To prevent the generation of defective work by supplying hot water up to a hot water level as a trial and deciding defective work based on the application of the output of a pressure sensor for a bath tub water level detection after a bath device is installed. CONSTITUTION:When the position of a pressure sensor 21 is set force as a standard, the pressure water head of a vacuum breaker 24 is defined as H1, while the pressure water head of a bath tub fill-up water level position A is H2 and the pressure water head of a trial supply hot water level position B is defined as H3. To avoid the incurrence of blame for defective work due to the installation height between a bath tub 10 and a bath heater 20, the pressure detected by the pressure sensor 25 when the bath tub 10 is filled up with water is required to be less than the pressure water head H1. In this case, bath tub water will not flow so reversely the water may not overflow from a vacuum breaker 24. When a position located directly above a circulation metal fitting 11 is set as a trial supply hot water level B, if the detected pressure of the pressure sensor 25, when the water level prevails on the water level position B, is less than H1-(H2-H3) or a value deducted from the pressure head of the vacuum breaker 24 by the difference between the water level positions A and B (H2-H3), no water will overflow from the vacuum breaker 24.

Abstract: PURPOSE:To improve the sampling rate, by giving an input signal to plural signal delay elements in parallel and sampling the signal by pulses with phases shifted from one another. CONSTITUTION:An input signal (g) is inputted to a delay element consisting of charge coupling elements 24-27. Clock pulses (h)-(k) having 90 deg. phase difference are applied to charge coupling elements 24-27. An output (l) of the charge coupling element 24 is applied to the base of a transistor (TR)28 to control the current flowed to a differential amplifier consisting of TRs 30 and 31. The TR30 is turned on at the timing when the clock is inputted to the charge coupling element 24. As a result, the output of the charge coupling element 24 appears in the collector of the TR30. Similarly, outputs of charge coupling elements 25-27 appear in collectors of TRs 34, 38, and 42 respectively. These outputs are synthesized and outputted.

Firstly, after the cleaning is started, washing liquid is supplied from a water supply tube 20 to a water tub 2 until a low water level is obtained in a state where the washing is housed in the drum 3. After that, preset rotating speed stored in a ROM in a microcomputer MC in advance is instructed from the microcomputer MC for global control of a drum washer, and the motor 9 is rotated, and a running-in operation is performed so as to sufficiently include the washing liquid in the washing for a while. After that, the volume of the washing is calculated by the microcomputer based on the conduction ratio of the motor and the change of it when the rotating speed of the motor 9 arrives at the preset rotating speed.

Title: Manufacture of silicon film
Inventor: AZUMA HIROZUMI
IPC: H01L21/20
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To form a silicon film with no high-temperature condition required by housing a silicate glass in a vessel, making the inside of the vessel to be reducing atmosphere, irradiating the silicate glass with a vacuum ultraviolet light of specific wavelength radiated from a vacuum ultraviolet ray source, and generating a silicon film on the surface of the silicate glass. SOLUTION: Such shape of silicate glass as a glass substrate 21 is allocated, in advance, at a supporting part 20 in a reactive vessel 1, and such a reducing gas as hydrogen gas is introduced from a gas supply part 10, and then, a vacuum ultraviolet light of wavelength 130 nm or shorter which is radiated from a vacuum ultraviolet light source 2 is point-condensed on the surface of silicate glass with condenser mirrors 8a and 8b to form a silicon film. Thanks to the quantum effect of vacuum ultraviolet light in wavelength range of 130 nm or below, SiO2 dissociates to silicon and oxygen, which is to be liberated, so that a silicon film is formed on a glass surface. If a reducing atmosphere is kept under a reducing atmosphere in the vessel at that time, dissociation phenomenon is promoted, so a silicon film is formed on the glass surface at a practical speed.

Abstract: PURPOSE:To reduce a frictionally contact part of each of rollers so as to reduce occurrence of damage by arranging the rollers so that their relative spaces are changeable, and by setting the total of gaps between the rollers arrayed in one row so as to be less than a predetermined value. CONSTITUTION:A roller bearing 1 has an inner race 2, an outer race 3 and several cylindrical rollers 4, and two annular flanges 5 are formed on the outer peripheral surface of the inner race 2, the several rollers 4 being held in one row between the annular flanges 5, 5 so that they are basically prevented from impacting upon one another.
