A component including a part having a concave and convex configuration for one of the enabling one of light convergence, light diffusion and light diffraction, being formed as a reflective film. The outline of the concave and convex configuration viewed from a right angle relative to a horizontal face has a half moon-shape, and a direction of a straight line part of the half moon-shape of each concave and convex configuration matches a direction of the horizontal face, and a plurality of the concave and convex configurations are combined.

A scroll compressor has an Oldhams ring made of sintered metal operating as a rotation-prevention mechanism for holding the rotation scroll. The Oldhams ring is formed to a size to accommodate the cutting work or the grinding work of the surface processing during the forming of the sintered metal, and, as a result, the productivity of the Oldhams ring can be improved and the wear resistance becomes excellent. A scroll compressor that is inexpensive and has a high reliability may be made of a hard sintered metal which has an excellent wear resistance. A first groove 3a and the second groove 3b are formed in the end face 3 of the ring 2 of the Oldhams ring into the sintered metal. And, after the processing, the first groove 3a is deepest, and the depth is progressively reduced in order of the second groove 3b and the end face 3 in the Oldhams ring. The wear on the corner part of the tool, which is easiest to wear being used to process the side face of the keys is reduced due to the presence of these grooves.

The present invention relates to method and apparatus for forming a thick film circuit by discharging a thick film paste from a paste discharging hole of a drawing nozzle and drawing a desired pattern on a substrate. The paste discharging hole has a substantially wide configuration and the drawing nozzle is rotated about its axis of rotation so that the longitudinal direction of the elongated cross-section of the paste discharging hole is substantially normal to the direction in which the drawing nozzle is moved with respect to the substrate.
摘要:
A method and apparatus for drawing a thick film circuit on a substrate (2) by discharging a paste from a paste discharge hole provided at one end of a drawing nozzle (1), the drawing nozzle (1) being located close to the substrate (2) and relatively moved with respect to the substrate (2). The discharge rate of the paste is controlled in accordance with the relatively moving speed between the drawing nozzle (1) and the substrate (2), thereby preventing variations of film thickness and line width caused by variations in the moving speed and making it possible to form a thick film circuit at a high speed and with high accuracy.
摘要:
A manufacturing method for an optical type recording and reproducing disc and the like, comprising the steps of, applying a coating liquid to opposite planar surfaces of the disc except for the central portions by rotating the disc, with the opposite planar surfaces of the disc being simultaneously dipped in the coating liquid, and thereafter, simultaneously curing the coating liquid applied to the opposite planar surfaces of the disc while rotating the disc.

An alkaline galvanic cell including a container serving for a cathode terminal, a sealing plate in the form of a layered clad plate serving for an anode terminal to be fitted into the container, and an insulating packing provided between the sealing plate and container for sealing the cell upon assembly. The cell is provided with a layer of epoxy adduct polyamide amine having amine valence in the range of 50 to 400 and disposed between the innermost copper layer of the sealing plate arranged to be readily amalgamated and the insulating packing so as to serve as a sealing agent or liquid leakage suppression agent.
