Title: Photoelectric switch
Inventor: MIYASHITA HITOSHI
IPC: G01V8/12
Filed: 1984-03-24
Abstract: PURPOSE:To facilitate the setting of a distance while dispensing with the replacement of parts, by inputting outputs of two logarithmic amplifier circuits to a differential amplifier in a change-over possible manner and adjusting the reference voltage of one comparator to perform the region reflective type and diffusion reflective type settings of the distance by one resistor. CONSTITUTION:When a change-over SW12 is set to an a-side, a diffusion reflective type mode is established and, when to a b-side, a region reflective type mode is set. Because the output of a second logarithmic amplifier circuit 5 and that of a third logarithmic amplifier 8 are inputted to a differential amplifier circuit 6 in a change-over possible manner and the reference voltage of a first comparator 7 is adjusted to the same variable resistor VR2 to perform the diffusion reflective type and diffusion reflective type settings of a distance, the setting of the distance can be performed by the same variable resistor in both uses as the region reflective type and the diffusion reflective type and the replacement of parts becomes unnecessary. Because a light receiving amount becomes important in the use as the diffusion reflective type, a photocurrent to the total quantity of light irradiating a position detection element 1 may be handled in order to prevent the erroneous operation of a circuit caused by the lack of the light receiving quantity.

Title: Silver paste
Inventor: FUKUHARA TORU
IPC: C23C30/00
Filed: 1992-02-07
Abstract: PURPOSE:To provide a silver paste capable of forming a thin-layer metallic silver film on the surface of a substrate without generating cracks or wrinkles. CONSTITUTION:This silver paste consists of a metallic silver powder, a glass frit and a binder, and the metallic silver powder contains >=50% of flat flaky silver powder. The silver paste is printed on a ceramic substrate 9, for example, and baked to form a thin-layer metallic silver film 10. The flaky silver powder is obtained by crushing a granular silver powder. The granular powder is squeezed to flakes which are mostly combinded with one another. Since the flaky silver powder contains only a small amt. of air, the air is not discharged to the outside during baking, and hence the thin film is not cracked or wrinkled.

Title: Dirt-proof water drain trap
Inventor: SUZUKI FUKUO
IPC: C08K3/38
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to maintain dirt-proof effect over a long period of time and also to realize deodorization effect by forming a thermoplastic resin composition blended with a particular amount of tourmaline powder to the thermoplastic resin and by constituting a dirt-proof water drain trap. SOLUTION: A thermoplastic resin composition is formed by blending 0.1 to 15wt.% tourmaline powder to a thermoplastic resin and a dirt-proof water drain trap is constituted. This tourmaline is a crystal electrically polarized without externally adding electricity, and the center of plus electric charge and the center of minus electric charge are deviated from the original positions. This deviation creates polarity and a surface activity is given to water contacting to the tourmaline. And the effect of resistance to bacteria and sterilization accelerates the surface activity of water of this water and the hydrolysis of chlorine dissolved in water, converts chlorine into HOCL- or COI- and these create the effect of bacteria resistance and others.
