The switch element and the pressing part respectively comprise four switch elements and four pressing parts that are respectively provided at intervals each having 90 degrees in the circumferential direction around the reference axis, and one pressing part is connected to another pressing part adjacent thereto in the circumferential direction around the reference axis by a flexible connecting element formed in a wave shape as viewed in a radial direction of the reference axis. | 09-10-2015 |
20140369871 | Compressor - A compressor includes a housing; a suction region and a discharge region which are formed in the housing in a partitioned manner. The compressor also includes a shaft which is pivotally supported in the inside of the housing. The compressor further includes a compression mechanism which sucks a refrigerant from the suction region and discharges the refrigerant to the discharge region due to a rotational motion of the shaft. The compressor further includes a bypass passage which makes the suction region and the discharge region communicate with each other, a valve element 41 which is capable of closing the bypass passage 40 from a discharge region side, and a spring which biases the valve element toward the discharge region side. | 12-18-2014 |
20140353131 | SWITCH - A switch comprising a body case, a movable board that is movably disposed in the body case and a movable contact point disposed in the movable board is disclosed. A fixed contact point is provided in the body case with a lubricating agent applied thereto. The movable contact point makes pressure-contact with the fixed contact point, and is connected and disconnected from the fixed contact point corresponding to a position of the movable contact point changing by moving the movable board. Grooves are formed in a contact portion of the movable contact point with the fixed contact point to be arranged along the movement direction of the movable contact point. | 12-04-2014 |
20140322979 | POWER FEED SOCKET AND CONTACT POINT UNIT USED THEREIN - A terminal/fuse assembly is fitted in a cylindrical, metallic inner case. The terminal/fuse assembly disposes a terminal penetrating through a bottom wall, a fuse and a contact point disc that overlap inside a housing composed of a plastic cover plate and a fuse box. The fuse is provided with a fuse body at a tongue piece extending inward from a ring portion in a peripheral edge of an elastic conductive plate. A part of the ring portion is supported in the upward position from the terminal. The contact point disc in contact with the elastic conductive plate at the support portion presses the fuse body downward, and thereby the tongue piece makes contact with the terminal to be conductive from the contact point disc to the terminal. | 10-30-2014 |

20140216910 | PUSH SWITCH - In an initial state where a push rod is pressed down, a base of a movable contact point board supporting a movable contact point makes contact with inclined protruding portions of a moving block by a second spring to be inclined. When the movable contact point makes contact with a fixed contact point following the projecting of the push rod, the base makes contact with stoppers. Thereafter, since the moving block alone rises, the movable contact point board rotates following the end edges of the stoppers according to release of the pressing by the protruding portion. Thereby the movable contact point largely slides and is displaced to the fixed contact point. | 08-07-2014 |

A retention space, defined by the orbiting scroll, the race, and the block, retains the medium. | 10-24-2013 |
20130167659 | DRIVE TORQUE ESTIMATION DEVICE FOR COMPRESSOR AND CONDENSER USED FOR THE DEVICE - A drive torque estimation device secures accuracy of a drive torque of a compressor by accurately grasping a flow rate of refrigerant in a cycle. The pressure difference is detected by a condenser as a resistor for calculating the flow rate. The pressure difference between two portions based on physical quantities relating to refrigerant pressures is detected using first and second sensors arranged at two portions in the cycle. A flow rate is calculated based on the detected pressure difference. The first sensor may be an upstream-side pressure sensor arranged at an inlet of the condenser or at a high-pressure side pipe upstream of the inlet and detects a pressure of the refrigerant flowing therethrough, and the second sensor may be a downstream-side pressure sensor arranged at a gas/liquid mixed phase region of the condenser and detects a pressure of the refrigerant flowing therethrough or may be a temperature sensor. | 07-04-2013 |
