Title: Metal part for producing glass ware and its production
Inventor: JINBA TAKAHIKO
IPC: C03B35/00
Filed: 1991-02-28
Abstract: PURPOSE:To prevent the generation of scratches on a glass ware by forming a graphite flame-coating film on the surface of a metal part for producing the glass ware. CONSTITUTION:Metal parts are used as jigs for holding glass wares and as constituting members on a production line for transferring molded glass wares to the next process in a glass ware production process. Scratches are generated on the glass wares with the contact parts of the needed metal jigs and with the transferring/sliding members on the production line. In order to avoid the generation of the scratches, flame-coated graphite films are formed on the contact parts. A flame-coating method is considered as a method for producing the coating films, but a single graphite can not be flame-coated. However, the employment of the graphite coated with a metal such as Ni or Al permits to form a metal-graphite coating film on the metal parts. The flame-coating may be performed by either of a gas flame-coating method and a plasma flame- coating method. The thickness of the coating film is desirably >=100mum for perfectly covering the metal substrate, because the surface roughness Rz of the coating film is several tens to 100mum.

Filed: 1990-05-07
Abstract: PURPOSE:To obtain high insulating and high light shielding characteristics by incorporating at least >=1 kinds of insulating org. pigment-dispersed resists or insulating transparent resists and conductive transparent resist into the above light shielding film. CONSTITUTION:At least >=1 kinds of the insulating org. pigment-dispersed resists or the insulating transparent resists and the conductive transparent resist are incorporated into the light shielding film.

Filed: 1983-06-29
Abstract: PURPOSE:To measure the pitch of marks, etc. existing on a moving object by using semiconductor sensors which can output information relating to the position of the incident point of light. CONSTITUTION:The image A0I of an aperture A is formed and position-sensitively detected in a (PSD) 1 at the point of the time t0 and A1I is formed at the point of t1. The image B0I of an aperture B is formed in a PSD2 at the point of the time t0. B1I is formed at the point of the time t1. The figure shows the unification and comparison of the directions where the image of the respective apertures of the PSDs move. If the length of the photodetecting surface is designated as Pl, (r) as the length from the symmetrical axis of the measuring object on the image forming plane of the PSD and the magnification of the image formed by a lens 31 as M (usually M<1), the min. measuring pitch LMIN corresponds to Pl/M in such a case when the image of the aperture of the measuring object appears at AI and BI. The max. measuring pitch lMAX is lMAX= (2Pl-2r)/M=2(Pl-r)/M in such a case when the image of the aperture of the measuring object appears at AI and BMAXI. Measurement is possible by making M>1 and magnifying the formed image when the length of the measuring pitch =Pl.
