Title: Method and apparatus for adjusting sensitivity of photoelectric type smoke sensor
Inventor: HORIUCHI SATOSHI
IPC: G01N21/53
Filed: 1989-08-11
Abstract: PURPOSE:To facilitate the setting of sensitivity and adjusting operation and moreover, enable the adjusting of a smoke sensor without variations with a simple construction by arranging an adjusting piece outside a projection area of a projection element in a smoke detecting section to be displaceable within a photo detecting area of a photo detector. CONSTITUTION:When a smoke sensor is put into operation, light from a projection element 6 is projected to a projection area L1 in a smoke detecting section D. On the other hand, an adjusting piece 94 is outside a projection area L1 of the projection element 6 and reflected lights of one order or several orders of a direct light of the projection element 6 are incident into a reflecting surface 98. Here, when a screw shaft 95 of a cover for adjustment is loosened and the adjusting piece 94 is started to turn centered on the screw shaft 95, the reflecting surface 98 begins to approach the projection area L1 of light projected from the projection element 6. As a result, reflected light incident into the reflecting surface 98 increases and with the increase in the reflected light, scattered light increases irradiating a detector 7 through a photo detecting area L2. This causes a change in quantity of light received by the photo detector 7 to allow the adjusting of detection sensitivity of the photo detector 7, thereby enabling the adjusting of sensitivity of the smoke sensor.

Title: Image forming device
Inventor: SUGANO MASASHI
IPC: B41J29/38
Filed: 1994-08-31
Abstract: PURPOSE: To automatically perform printer operation when a signal is inputted and to improve operability by switching a function to a printer function in the case a finally used function is a copying function after the lapse of specified time in a non-actuated state. CONSTITUTION: This image forming device ordinarily rushes in an energy conserving mode 13 after the lapse of specified time, and is set in a printer mode 16 by inputting printer information in a controller command 14 from the outside. The device releases the energy conserving mode 13 and performs printer operation. In the case of performing copying operation, a copying mode is set by the key operation of an operation key input 15. When copying is finished, the device is restored to the energy conserving mode 13 again. Namely, by inputting the printer information from the outside, the device is immediately set in the printer mode 16, and only when input operation is performed by the key operation 15, the copying mode is set. Therefore, operation for switching to the printer mode after the copying mode is unnecessitated, and the printer operation is made more efficient in the device.

Title: Semiconductor device
Inventor: OBA TAKAYUKI
IPC: H01L21/314
Filed: 1989-08-10
Abstract: PURPOSE:To prevent hydrogen from diffusing in a semiconductor substrate and to improve the reliability of a device by a method wherein the device is provided with a layer which absorbs the hydrogen exising in insulating films. CONSTITUTION:A composite film 8 consisting of a metal layer 82, which consists of a metal which absorbs hydrogen to make a hydride, and insulating layers (silicon nitride layers) 81 and 83 is provided on a semiconductor substrate 1 with an element formed on it. A nitrogen-containing insulating layer, such as a silicon nitride layer, contains much hydrogen, where there is the metal layer, which absorbs hydrogen to make a hydride, the hydrogen is absorbed in this metal film. For example, as a metal layer to absorb hydrogen well, a palladium (Pd) layer is formed. Thereby, as hydrogen existing in a surface protective film and an interlayer insulating film can be captured by the metal layer, the diffusion of the hydrogen in a substrate is suppressed and the generation of hot electrons in the substrate can be deterred.

Since the solid electrolyte 4 prevents the elution of polypyridine into an acidic aqueous solution, capacity and cycle performance are increased. By using a positive electrode containing an active material of polyaniline or benzoquinone, or by combining this positive electrode with the negative electrode, similar effect can be obtained. By replacing part of the solid electrolyte 4 with the electrolyte solution or the gel electrolyte, ionic conductivity is enhanced.  A polymer of perfluorocarbon sulfonate or polyether-based having polyoxyethylene skeleton is preferable as the solid electrolyte 4.

Title: Tube bender
Inventor: IZAWA TOSHINORI
IPC: B21D7/024
Filed: 1985-09-20
Abstract: PURPOSE:To prevent damage of a tube and to reduce a manufacturing cost by removably setting a plastic protective member on a sliding part along a tube on a movable or holding type die. CONSTITUTION:A pressing die 12 is installed as a holding die and a protective member 16 made of a plastics such as nylon is fitted on a base body 15 removably. A forming part 13a is formed so as to match the bending curvature on the left end of a bending die 13. A clamp die 14 approaches the bending die 13 and goes away from it so as to clamp and release a tube 11 through a driving device. The dies 13 and 14 pivot around a center O in the direction of the arrow (b) to the pressing die 12, so that the tube 11 is bent along the curvature of the forming part 13a. In that time, the tube 11 slides on the protective member 16, but damage of the tube 11 is prevented because of a small friction coefficient of the member 16. The manufacturing cost is also reduced since a worn member 16 is replaceable.
