Title: Push button device
Inventor: TAKAHASHI MASAHIRO
IPC: H01H13/14
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To limit the length in the shaft line direction or in the sliding direction of a push button to the necessary length and smoothly operate the push button by installing a projecting streak extending in the direction moved by pushing of the push button in the push button, and installing a guide part for guiding by accepting the projecting streak in a cabinet of an apparatus to which the push button is mounted. SOLUTION: Inclining of a push button to the lower part along the surface of a bezel 11 or a screen is prevented. Since a projecting streak 39 of an elastic piece 37 of the push button is supported from the lower part with a guide part 25 on the bezel 11 side and slid, the push button is always operated in a correct posture. Such a trouble that a pushing operation part is inclined to a cylindrical guide part 23 and comes in contact with an edge part of a circular opening to concentrate stress or move becomes non-smooth can be prevented. Since the push button is smoothly operated, a push button switch with high operation feeling can be provided.

Abstract: PURPOSE:To obtain performed particles, provided with large diameters of bubbles, by a method wherein a mixture is discharged into a low-pressure area after passing it through a plurality of choking plates, which are arranged in series in the discharging direction thereof. CONSTITUTION:Thermoplastic resin particles 2, dispersed into water 3 containing a dispersing agent, are impregnated with a volatile forming agent in a pressure vessel 1 and the mixture is heated to a predetermined temperature to keep it at a predetermined pressure under the pressure of the vapor of the volatile foaming agent, thereafter, a discharging valve 8 is opened to discharge the mixture into a low-pressure area through a discharging pipeline 5 and choking plates 6, 7 whereby the prefoamed particles of the thermoplastic resin are obtained. A pressure in the pressure vessel 1 is reduced to a pressure lower than the predetermined pressure as the mixture is discharged, therefore, the predetermined pressure is kept by adding the volatile foaming agent into the pressure vessel 1 through the pipeline 9. The diameter of the bubbles of the performed particles obtained in this process is larger than the diameter of the bubbles in conventionally prefoamed particles by the degree of 1.3-2.0 times, therefore, a molded from after molding is small in the volume contraction and prominent in the appearance of the surface thereof.

Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a device having simple constitution, which is easy to adjust and highly reliable and can discriminate whether or not a bill, a bond, etc., are genuine. SOLUTION: The sensitivity of a photoelectric converter 24 is adjusted equally between a light source A and a light source B which emit lights differing in wavelength in the absence of an object to be identified. In this state, the sensitivity difference of the detection signal of a light which is transmitted through an object to be identified is detected as the output of a high-pass filter 26 and a sampling circuit 15 samples a signal proportional to the difference in the sensitivity of the detection value from the light source A based upon the sensitivity difference from the light source B and discriminates genuineness according to the sampling value.  When there is no object to be discriminated, a period wherein the adjustment is not continued by always performing alternate light emission and only the light emission is stopped while an adjustment level is held is periodically provided to suppress the deterioration of the light sources.

Abstract: PURPOSE: To prevent the deteriration of separation capability caused by filter cakes and to effectively use a separating layer continuously for a long time, by providing a fluid separating part through a separating layer provided on the side wall of a spiral flow path.  
     CONSTITUTION: While raw fluid flowed in from the direction of arrow A, passes through a cylinrical coil-shaped flow path 6, only media pass through a separating layer, which is constituted of a separating membrane 5 and a comparatively rigid filtering material 4, by the pressure difference between the path 6 and a fluid separating part 7. Then the media pass through the separating layer to enter the liquid separating part 7 and flows out from a separated-liquid exit port 10. On the other hand, the concentrated fluid having a decreased proportion of the media flows out in the direction of arrow B. Though the filtered cake starts depositing on the surface of separating layer with the lapse of time, the amount of cake is controlled by keeping the fluid velocity comparatively higher or by changing the velocity and according to the circumstances, the cake is removed.
