Title: Light emission controller
Inventor: MATSUDA SEIJI
IPC: H04B10/548
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a light emission controller in which increase in the service life and power saving of a light emitting device are attained with respect to the light emitting device providing the output of an optical signal in response to an input signal. SOLUTION: The controller is provided with a signal detector 3 and a light emitting device controller 4 and only when the signal detector 3 detects a signal of a preset transmission object, a light emitting device 5 emits an optical signal modulated by a signal at a prescribed level or over. On the other hand, when the signal detector 3 does not detect a signal of the transmission object, since the light emitting device 5 decreases the light less than a prescribed level or stops light emission, the power consumption is reduced and the service life of the light emitting device 5 is continued longer.

Abstract: PURPOSE:To exactly detect a mark, and also to make a device small-sized and simple, by using a microcomputer for controlling a mark detecting operation. CONSTITUTION:A sensor group 2 is placed on length L which covers width (l) of a polarization plate 1 fed to an inspecting position as a continuous band-like thin plate. Also, on the surface where a unit sensor 21 is opposed to the polarization plate 1, for instance, photodetecting fibers 41-43 and 51-53 on both sides in the moving direction of the polarization plate 1, which have placed 3 light emission fibers 31-33 between them, that is to say, 9 optical fibers are bundled.

Title: Production of master sheet for electrolyzing nickel
Inventor: TAKAHASHI NOBUO
IPC: C25C1/08
Filed: 1990-06-28
Abstract: PURPOSE:To obtain a master sheet which is not midway peeled and is easily peeled after manufacturing and is unnecessary to cut and shape the peripheral part by making the aperture area of an anode box smaller than the electrolytic area of a cathode. CONSTITUTION:A mother board which has the smooth surface and is made of stainless steel is utilized for a cathode. An insoluble electrode is utilized for an anode. The distance (D) of both the wall face of an anode box for recovering generated gaseous chlorine and the cathode is regulated at 0.02 times to 0.2 times of length (L) of a diagonal line of the cathode. The aperture area (AB) of the anode box is regulated at 0.1 time to 0.9 times of the electrolytic area (AC) of the cathode. Thereby the anode box is utilized as a shielding plate. When the distance D is less than 0.02 times of the length L, effect of the shielding plate is made excessively large. Only the peripheral part of electrodeposited nickel is made extremely thin and shaping is necessitated. When the distance D exceeds 0.2 times, peeling from the mother board is not inhibited and electrolytic voltage is raised even when the area AB is made small. Further, when the area AB exceeds 0.9 times of the area AC, effect of the shielding plate is not shown. When it is less than 0.1 time, electrolytic voltage is extremely increased because the current density of the anode is raised. Current is concentrated in one part and the state of the surface of the master sheet is impaired.

Title: Stainproof crystallized glass
Inventor: SUGANO MITSUMASA
IPC: F21Y101/00
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a crystallized glass with a stainproof coating with excellent durability and stainproof properties. SOLUTION: A crystallized glass is coated with a stainproof coating prepd. by dispersing simiconductor photocatalyst particles in a matrix consisting of a titania-silica glass. A photocatalyst is photo-excited in the daytime by irradiation of the sun light and the surface of the stainproof coating is made ultrahydrophilic thereby. As the ultrahydrophilic surface is hardly electrostatically charged, soot and dust hardly adhere to it. During rainfall, the soot and the dust adhering to the surface are washed out by rain water and the surface of the crystallized glass is self-cleaned. As the coefficient of thermal expansion of the titania-silica glass is close to the coefficient of thermal expansion of the crystallized glass, there exists no possibility of peeling-off of the stainproof coating even when a cycle of cooling and heating is applied.

Title: Burner device with recuperator
Inventor: YOAHIMU BIYUUNINGU
IPC: F23D14/78
Filed: 1980-11-29
Abstract: In order to permit operation with preheating of the combustion-supporting air to 50 or preferably 65 percent or more of the oven temperature, the air is fed to a ceramic burner tube through an annular nozzle directing it in an annular jet along the interior walls of the burner tube. For a burner of low back pressure having no restriction at the mouth of the ceramic burner tube, the ceramic burner tube fits over the end of the outer member of the annular nozzle and some of the combustion product gas, flowing from the oven into the burner structure for countercurrent of the preheating of the air supply, is sucked into the underpressure zone between the annular air jet and the inner wall of the burner tube through a small annular gap where the burner tube fits on the air-supply nozzle. For a burner design involving considerable back pressure, the ceramic burner tube fits within the outer wall of the annular nozzle with a very small clearance in the overlap and some of the supplied air, which is at higher pressure than the exit in gases, escapes through the gap around the outside of the burner tube and cools the burner tube and the adjacent overlapping portion of the air supply tube.
