Abstract: PURPOSE:To completely remove a coating without any residual insulator by forming an absorbing layer between a conductor and an insulating film by a carbon evaporation film formation method and increasing the absorptivity of laser light in the periphery of the boundary. CONSTITUTION:Polyester with a prescribed thickness is used for an insulator 2 and copper is used for a conductor 3.

Laser light is converged on an insulated electric cable by using lens and thus carbon dioxide gas laser whose radiation energy density is adjusted is radiated to the insulated electric cable for a prescribed radiation period with prescribed frequency and prescribed times. Consequently, the insulating body 2 and carbon evaporated film are completely removed without damaging the conductor 3 at the beam radiated parts of the insulated electric cable. As a result, the coating removed parts can have good wettability to solders without being coated with fluxes and have sufficient electric conductivity.

Title: Closed motor-driven compressor
Inventor: TADA TAKEMI
IPC: F04B39/10
Filed: 1989-07-19
Abstract: PURPOSE:To reduce noise comparatively simply and inexpensively by making a structure in which a border position between a side plate discharge valve fixation seat surface and a side recess portion, and a border position between a discharge valve guard flat portion and a discharge valve guard R bending portion, are made to agree. CONSTITUTION:In the length from a fixed end of a discharge valve 2 to the tip, the length part of a flat part 1a of a side plate 1, a border portion of a recess for relief portion 1d and an R bending portion of a valve guard 3 is shortened by coinciding the border portion of the flat portion 1a of a side plate 1 and a bending portion of the valve guard 3. In this way, the proper vibration of a discharge valve becomes high, and the sound of resonance, which occurs at the time of the opening/closing action of the discharge valve 2 in the compressor running, is prevented, and the noise can be reduced. Also, there is no increase of a cost, as such means as thickens the plate thickness of the discharge valve 2 or the like is not used, which is due to heighten the proper vibration number of the discharge valve 2, and also there is no fear of the lowering of performance caused by the delay of the opening/closing of a valve or the like, as the shape of the valve guard 3 is the same as the prior one, and the lowering of noise can be realized with a comparatively inexpensive and easy structure.
