Title: Method of installing wave absorber for microwave oven
Inventor: YAMAZAKI HIROKA
IPC: H05B6/76
Filed: 1992-05-14
Abstract: PURPOSE:To prevent a wave leakage by utilizing initial room temperature characteristic. CONSTITUTION:The wave absorbing part 2 and locking claw 4 of a wave absorber 1 are integrally molded from materials of the same kind by means of injection molding. As the material for formation, for example, those in which soft ferrite powders such as manganese zinc ferrite and nickel zinc ferrite, or magnetic materials such as carbon, magnetite, and carbonyl iron are dispersed in synthetic resin binders are used. These have initial room temperature characteristic having plasticity allowing the engaging action to a mounting part, and the plasticity is lost when an accumulated time of a fixed time or more passes under a high temperature state of a determined temperature of higher. Such binders, for example, include polymethyl pentene, polypropylene and the like. The binders are hardened by the continuous or intermittent exposure to the high temperature environment, and the form of the installed state is fix. Thus, the absorber 1 never rattles or falls off and a wave leakage can be prevented.

Filed: 1994-06-30
Abstract: PURPOSE:To record only an image without recording a black frame even when a video signal outputted from a game machine or the like is a composite video signal with a narrower range than the standards by segmenting a prescribed range of composite video signals for each scanning line into a storage means, discriminating the range of the video signal, extracting only the video signal and printing it out.

Title: Printable polyolefin sheet
Inventor: TANAKA MITSUO
IPC: C08J7/00
Filed: 1986-06-25
Abstract: PURPOSE:To provide a sheet having favorable affinity for an offset printing ink, capable of being clearly printed with excellent adhesion of the ink and capable of being printed in multiple colors by a single offset printing operation, by the combination of the addition of a small amount of a fatty acid ester of a polyhydric alcohol as an antistatic agent with a corona discharge treatment. CONSTITUTION:A fatty acid ester of a polyhydric alcohol may be a fatty acid ester of polyethylene or of sorbitan, and it is added in an amount of not more than 0.1 wt.%, preferably, not more than 0.07 wt.%. Addition of 0.1 wt.% or more of the ester is undesirable because it may cause bleading of the ester to the surface of a sheet, thereby impairing transparency. An antistatick effect can be greatly enhanced by subjecting both sides of the sheet to a corona discharge treatment, and the sufficient antistatick effect thus obtained leads to the effect of preventing two sheets from being simultaneously fed at the time of printing and the effect on the separation of each sheet before and after printing, whereby printing can be smoothly performed.

Abstract: PURPOSE:To improve handling by replacing a portion of a tooth end arched section of a referential rack tooth in a point contact WN gear with an involute curve thereby considerably relieving the sensibility of the portion near to the tooth tip against the central distance error. CONSTITUTION:With respect to the tooth profile of a referential rack in a point contact WN gear to be obtained through profile shifting while employing a referential rack having such tooth profile as concave/convex arches having same radius and intermediate lines connecting them are combined, the portion of the tooth end arched section near the tooth tip is replaced with an involute curve having curvature gradually reducing toward the tooth tip thus to perform correction. WN gear is a helical gear and the rack is also a helical rack thereby the referential rack tooth profile is defined on proper cross-section of referential rack. In other word, the arch (dashed line) from the points A, E at the tooth end (pressure angle alpham) to the tooth tip is replaced with an involute curve (solid line).

Abstract: PURPOSE:To prevent the generation of interference fringe patterns by providing the 1st layer consisting of an amorphous material contg. Si atoms and Ge atoms and the 2nd layer consisting of an amorphous material contg. Si atoms and distributing, ununiformly in the layer thickness direction, the Ge atoms in the 1st layer and the material which is incorporated into a least either of the 1st layer and the 2nd layer and governs conductivity. CONSTITUTION:Reflected light R1 and exit light R2 with respect to incident light I0 advance in the directions different from each other when the boundary face 703 between a layer 701 and layer 702 and layer 702 and the free surface 704 of the layer 702 are non-parallel. The degree of interference is therefore decreased and the quantity of the incident light in the very small part is averaged. A plasma vapor phase method, optical CVD method and thermal CVD method which can control the layer thickness at an optical level are used for forming the 1st layer contg. the silicon atoms and germanium atoms and the 2nd layer contg. silicon atoms constituting the photoreceptive layer. The base is formed by machining to have a desired smoothly rugged shaped, pitch and depth. The generation of the interference fringe patterns in the image forming stage and the spots in the reversal developing stage is thus prevented.
