摘要： A hammer sensor includes a photo-filter plate movable together with a hammer assembly and having a base plate fixed to the hammer shank and an arc pattern formed on the base plate and different in transparency from the base plate, a photo radiating element radiating a light beam toward the arc pattern and a photo detecting element disposed on the optical path of the light beam for converting the amount of transmitted light to an electric signal, wherein the photo-filter plate converts the rotational angle of the hammer assembly to the amount of light incident on the photo detecting element, and makes the photo radiating element and the photo detecting element stationary so that a suitable photo-shield case prevents the photo elements from environmental light.

摘要： An attempt has been made to prevent damage of a hermetic terminal and to improve pressure-resistance strength of the welded joint of connecting pipes in order to provide a sealed housing 4 having a pressure-resistance strength high enough to allow use of a high-pressure alternative refrigerant. For this purpose, ring-shaped metal members 15 and 23 are welded to the outer peripheries of the welded joints of a hermetic terminal 8 to be hermetically welded to an upper end plate 1 of a sealed housing 4 and a discharge pipe 10. As a result, in the event the internal pressure of the sealed housing 4 increases and the upper end plate 1 deforms in the shape of a sphere, the ring-shaped metal member 15 on the outer periphery of the welded joint of the hermetic terminal 8 suppresses the deformation of the hermetic terminal 8 thus preventing damage of a glass seal 12 of the hermetic terminal 8, and the ring-shaped metal member 23 on the outer periphery of the welded joint of the discharge pipe 10 decreases the tensile stress produced in the welded joint of the discharge pipe 10 thus improving the pressure-resistance strength of the connecting section of the discharge pipe 10 thereby providing a sealed type compressor having a sealed housing 4 with a sufficiently high pressure-resistance strength.

摘要： An integrally molded automotive waterproof connector is disclosed which comprises a thermoplastic resin and integrated therewith an oil-bleeding silicone rubber, the thermoplastic resin containing a thermoplastic resin oligomer containing at least one aliphatic unsaturated group. In the connector, the adhesion between the thermoplastic resin and the silicone rubber is satisfactory regardless of the length of storage period as compared with connectors comprising a thermoplastic resin and a silicone rubber integrated therewith after priming. Further, the connector of the present invention is excellent in production efficiency and workability, is reduced in connector housing fitting force, and can retain satisfactory waterproofness.

摘要： In a scroll compressor, a stationary scroll is pressed toward a movable scroll by a back pressure of a discharge fluid compressed by a compression mechanism, and wear powder, produced from an annular seal (which receives the pressure of the discharge fluid) as a result of precession of the stationary scroll, is arrested, thereby achieving the scroll compressor high in efficiency and reliability. A pressure-receiving surface for receiving a back pressure of the discharge fluid so as to press the stationary scroll toward the movable scroll is formed on that portion of the stationary scroll disposed around a communication port which is formed in the stationary scroll, and communicates with a discharge port. An annular seal is provided to form a seal between the stationary scroll and an upper frame around a region of communication between the communication port and the discharge port in such a manner as to satisfy a necessary annular sealing surface area, and a circumferential recess is provided on that side lower in pressure than this annular seal.

摘要： A scroll compressor has a closed vessel in which a compression mechanism having orbiting and stationary scroll elements in engagement with each other is accommodated. A crankshaft is coupled with the orbiting scroll element and rotatably supported by a crank bearing. The crankshaft is rotated by an electric motor having a stator and a rotor so that the orbiting scroll element may orbit relative to the stationary scroll element. A plurality of balance weights are provided for maintaining static and dynamic balances of rotary elements including the orbiting scroll element, the crankshaft, and the rotor. The static and dynamic balances are calculated using at least a clearance between the crankshaft and the crank bearing.

摘要： A scroll compressor has a closed vessel, a compression mechanism accommodated in the closed vessel and including a non-orbiting scroll and an orbiting scroll in engagement with each other, and an electric motor for driving the compression mechanism. The non-orbiting scroll includes a frame portion and a non-orbiting end plate axially movable relative to the frame portion. The frame portion has a recess defined therein and a pin secured thereto. The non-orbiting end plate has a cylindrical wall integrally formed therewith and loosely received in the recess, thereby radially positioning the non-orbiting end plate relative to the frame portion. The non-orbiting end plate also has a recess defined therein in which the pin is loosely received, thereby circumferentially positioning the non-orbiting end plate relative to the frame portion. The pin is hardened so as to have a Rockwell hardness of more than 35 on scale C and has a chemical compound layer deposited thereon, to thereby minimize wear thereof.
