Patent CA-1292298-C (CA)
Title: Gas sensor and method of manufacturing the same
Inventor: IPPOMMATSU MASAMICHI
IPC: G01N27/12
Filed: 1987-11-04
Granted: 1991-11-19
Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a gas sensor, particularly, an inflammable gas sensor for detecting an inflammable gas, such as leaked natural gas.  The sensor comprises an n-type metal oxide semi-conductor film, such as SnO2 film, whose resistivity varies responsive to  the detection of the inflammable gas.  The semi-conductor film is covered on its surface by an oxide film insulator made of an oxide such as SiO2, MnO, MnO2 and V2O5.  While the inflammable gas which may contain ethanol passes through the oxide film insulator, the concentration of the more reactive ethanol decreases and as a result, the sensitivity to methane and hydrogen is improved.  Also disclosed is a preferred production method of the sensor.  The process involves (1) the formation of the n-type metal semiconductor film, (2) the formation of electrodes and (3) the formation of the oxide film insulator on the n-type metal semiconductor film by sputtering through an opening of a mask placed over the electrodes.  The opening of the mask has a speci-fic size with respect to the thickness of the mask.

Granted: 1992-08-25
Abstract: ABSTRACT OF THE DISCLOSURE A single shaft agitate and spin drive for an automatic washer is provided in which a lost motion mechanism or clutch in the form of a plurality of stacked discs is mounted on the agitator shaft, a lower end of the mechanism being driven by the agitator shaft and an upper end of the mechanism driving the basket after a sufficient amount of rotation by the agitator has been inputted to the mechanism.  The mechanism absorbs enough rotational motion to allow oscillatory motion of the agitator without transmission of that motion to the basket, but if sufficient rotational motion is input to the mechanism, such as during the spin mode, the mechanism transmits the motion to drive the basket.  The amount of rotation absorbed is easily changed by changing the number of discs in the stack.

Granted: 1993-11-16
Abstract: ABSTRACT         In order to selectively jam M selected channels to selected subscribers in a CATV system, each of M different oscillating signals, each of which oscillating signals has a duration longer than the duration of the horizontal synchronization signal of the television channel it is to jam and a frequency higher than the carrier wave of the channel is is to jam, are in turn added to the television signal circuits of those subscribers who are not authorized to recieve the particular channel being jammed by the jamming signal being added.  The television set of the non-authorized subscriber picks up the higher frequency jamming signal as the valid horizontal synchronization signal and therefore ignores the valid horizontal synchronization signal, with the result that the channel in question is unviewable on the the television set of the non-authorized subscriber.

Abstract: Abstract A  non-circular  cross-section  coil  spring,  wherein  a spring  wire  having  a  non-circular  cross-section  shape  is coiled into such configuration that a major diameter of the cross-section is directed in the direction intersecting with a center line of the spring.  Torsion is preliminarily given to at least a part of the spring wire so that the coil spring inner  circumferential  surface  side  of  the  above-mentioned major diameter may be deviated to a free end side of  the spring with reference to the reference plane of extension and contraction of the coil spring in the case where the coil spring is a compression coil spring, but to the side of the aforementioned reference plane of extension and contraction in the case where the coil spring is a tension coil spring.          In a coil  spring comprising a larger  pitch portion and a smaller  pitch  portion,  a  large  angle  of  torsion  is preliminarily given to the larger pitch portion and a small angle of torsion is preliminarily given to the smaller pitch portion.  Upon application of a load, an angle of torsion of the spring wire becomes zero or nearly zero, thereby increase of  the  maximum  shearing  stress  generated  at  the  inner circumference of the coil spring can be suppressed, and also sharing stress in the spring wire can be made uniform.
