Title: Pressure release structure of milking device
Inventor: UEHARA HIROYUKI
IPC: A01J1/00
Filed: 1988-01-25
Abstract: PURPOSE:To reduce the number of parts and to improve the assemblage, by making a valve, including a valve body, a collar and a lever, of a rubber-like elastic body, by fixing the valve body on a valve seat by elasticity of the collar and by elastically deforming the valve body by pressure of the lever to make an air aperture open. CONSTITUTION:When a lever 25 is pressed with a finger, a fulcrum 26 of a valve 21 comes in contact with a projection 27 of a joint 8, and a bending moment generates around the contact in the valve 21. Since the valve 21 is made of a rubber-like elastic body with high elasticity, the reaction of the projection 27 against the pressure of the lever 25 causes elastic elongation of a valve body 22, makes the diameter of the valve body 22 smaller and thus makes a clearance between the valve body 22 and an air aperture 20. An air passage connects to the outside via the clearance and thus the pressure in a cup 4 returns from the negative to the ordinary one; that is, the sucking power is extinguished and the cup 4 is easily removed from a mamma. When the pressure of the lever 25 is cleared, the valve body 22 is seated in the opening of the air aperture 20 to close it by the restoring force of a collar 24.

Title: Structure of push button
Inventor: TAKAGI TAKEMI
IPC: H01H13/12
Filed: 1980-02-04
Abstract: PURPOSE:To realize utilization of the inner center of a push button for display of channels for a push button of a channel selection device incorporating a circuit that performs an electrical switching of channels, by providing an elastic material which is deformed with depression of the push button and then adding the channel selection switch operation bar close to the elastic material. CONSTITUTION:The push button 10 is attached in such way that its head part 10a protrudes through the hole 12 provided on the front plate 11. On the other hand, the hollow part 15 is formed to the base 14 to store the cylindrical elastic material 16. In addition, the operation bar 18 of the channel selection switch 17 is provided at the part 15 close to the material 16. When the button 10 is depressed in the direction of the arrow (a), the material 16 is deformed into an oval shape to drive the bar 18. As a result, the switch 17 is turned on. When the pressure of the button 10 is released, the deformation of the material 16 is cancelled. Thus the button 10 is pushed back by the elastic force of the material 16, and at the same time the driving force of the bar 18 is released. As a result, the switch 17 is turned off.

Title: Water stop device
Inventor: UNO SHIGEKI
IPC: F16K17/10
Filed: 1986-01-23
Abstract: PURPOSE:To completely drain a water, by providing a main valve spring between a diaphragm and a main valve seat for biasing to separate the diaphragm from the main valve seat. CONSTITUTION:A main valve spring 13 is provided between a diaphragm 7 and a main valve seat 8. A spring force of the main valve spring 13 is set to be greater than a resilient force of the diaphragm 7 but smaller than that of a water stop spring 5. In draining a water, a main cock is first closed, and a pilot valve shaft 9 is drawn by an external force. A pressure differential between pressure P1 and P2 is nullified by stopping the main cock. Under this condition, the spring force of the main valve spring 13 acts to move the diaphragm 7 toward a pilot chamber 3 until the diaphragm 7 abuts against a rib 12 for restricting a diaphragm stroke. Thus, the drainage may be carried out.

Title: Control-type rear suspension
Inventor: TAKAGI RYUGO
IPC: B62D21/11
Filed: 1989-01-23
Abstract: PURPOSE:To make riding more comfortable by controlling the rigidity of an insulator between a suspension member and a car body to change an elastic resonance frequency as an input frequency that gives vibration to the suspension member approaches the elastic resonance frequency. CONSTITUTION:At a car speed, e.g., a slow speed, at which a road surface input frequency from a tire approaches the elastic resonance frequency of a suspension member, a solenoid 22 of an insulator 11 linking the suspension member to a car body is energized to move a valve 23 downward to close a communicating hole 20, thereby blocking the flow of a fluid between fluid chambers 18, 19 with the resulting increased rigidity. Then, when a medium speed is reached, a solenoid 21 is energized to move the valve 23 upward to open the communicating hole 20, thereby allowing the fluid to move between the chambers with the resulting reduced rigidity and departure from the elastic resonance frequency. At a high speed, the order component frequency of an engine revolution speed approaches the elastic resonance frequency of the suspension member, requiring the rigidity of the insulator 11 to be increased. In this manner, it is possible to make riding more comfortable.
