Title: Ceramic plate step difference discriminating system
Inventor: FUJIMOTO RYOKO
IPC: H05K13/08
Filed: 1988-09-08
Abstract: PURPOSE:To discriminate whether step difference exist on a ceramic plate or not by irradiating the ceramic plate with the linear laser light from a light projector and receiving the reflected light by a photodetector and amplifying only a momentary change electric signal part out of electric signal components from the photodetector and outputting the output by a differential amplifier. CONSTITUTION:The upper face of a ceramic plate 2a is irradiated with linear laser light 5 from a light projector, and the reflected light is received by a photodetector 6. When the ceramic plate 2a is slided on a supply rail 1, the quantity of reflected light made incident on the photodetector 6 is reduced to momently change the electric signal of the photodetector 6 only the moment a step difference part 2e of the ceramic plate 2a passes the irradiated spot position of the laser light 5. Only this signal is amplified by a differential amplifier 7 and is outputted to a step difference discriminator 8. The discriminator 8 outputs a step difference discrimination signal if the output is outputted from the differential amplifier 7 while a ceramic plate passage detecting sensor 3 detects that the ceramic plate 2a is passing. Based on the output of this signal, ceramic plates 2b having no step difference are excluded, and a thick ceramic plate 2d and a thin ceramic plate 2c are arranged and are automatically supplied.

CONSTITUTION: In a thick plain tile X where a nail hole 10 is bored on the bottom side R, a locking receiver 2a separated from a water conduction band 1 by a back board is formed on the T side of the head of an insertion receiver U. A locking projection 3a having a rear surface portion higher than the surface of the tile and projecting outside the bottom R of a tile X is further formed on a flashing near the central part on the bottom side R. The portion of the water conducting band 1 of a file X on the slanted upper stage tile is loaded on a water flowing surface 12 of a slanting lower stage tile X, thereby fixing the locking receiver 2a of the tile X with the locking projection 3a of the tile X. It is, therefore, possible to prevent the tiles from being turned up during a storm and the deviation of the tiles and re-penetration of water as well.

Abstract: PROBLEM TO BE SOLVED: To surely perform transmission when a free area is present in the wavelength variable length of an LD and to reduce useless areas by forming one or more groups of wavelengths for which the intervals of the adjacent wavelengths are respectively controlled within a wavelength range detectable by a wavelength detection means. SOLUTION: The wavelengths of the semiconductor lasers (LDs) of respective terminal stations form some groups of a Δλinterval within the wavelength range of a communication system and the wavelengths of the LDs of the respective terminal stations enter a prescribed group present within the wavelength variable range of the LD. In this case, a wavelength control system 21 controls an LD drive circuit 24 and an optical filter drive circuit 25 and performs a tuning operation based on the binary output signals of an identifier 28. Then, transmission is started by the wavelength at the end of the wavelength variable range or the end of the free area of the wavelength variable range of the LD 22 of the terminal station and the channel interval Δλ is maintained with an adjacent channel thereafter.  As a result, wavelength arrangement for forming some groups of the Δλ interval is attained.

Filed: 1985-10-09
Abstract: PURPOSE:To satisfy the mechanical strength and lubricity required for respective parts by forming a helicoid cylinder into laminated structure consisting of a skin material on the surface and a core material on the inside and forming a part for mounting attachments of a core material by die molding. CONSTITUTION:The skin material consisting of a polycarbonate resin is injected by an injection cylinder 32A into the cavity for forming the helicoid cylinder 22 in a metallic mold and thereafter the core material is injected therein by an injection cylinder 32B to make sandwich molding. The previously injected skin material is pressed to the peripheral wall of the cavity by the core material. The part 22f for mounting the attachments and a projecting part 22h are coaxially disposed. The skin material is packed to the inside wall of a key groove 22e but does not reach the part 22f where the core material is packed. The part 22f of the helicoid cylinder is thus formed to have the high mechanical strength. The helicoid cylinder part 22a and key groove part 22e are formed to satisfy both requirements for the strength and lubricity by the lamination of the skin material on the surface and the core material on the inside.

Abstract: PROBLEM TO BE SOLVED: To arbitrarily take out and in chairs for a necessary number of people by winding a carpet when chairs are necessary, drawing the housed chairs to the upper floors for use, pulling up and returning the seats to the original form after use, lowering the chairs to the lower floor, and extending the carpet to the original form. SOLUTION: A board is managed every group of the first group, the second group and third group as occasion demands. In case of a small number of people, only the first group is UP to raise the chairs neatly on the hall floor, and DOWN to lower the chairs to the ground floor after use when the hall is OK. The chairs are sectionally managed by designating a certain number of a certain group according to this method. A carpet is usually laid, and when chairs are necessary, the carpet is wound on one side by a carpet winding device to expose an easy chair outlet port, and the housed chairs are raised to the upper floor. When a sitting person presses a handle situated on the upper end of the chair, the seal is fallen forward, and the person sits therein in this state. After use, the seat is pulled up and returned to the original state.
