Inventor: KAGECHIKA HIROSHI
IPC: C25D5/10
Filed: 1979-10-15
Abstract: PURPOSE: To manufacture steel sheet described in the titled having especially excellent corrosion resistance, by dividing an electrodepositing process into an deposition step for the initial layer and a depositing step for the build-up layer, and by specifying the quantities of a surfactant contained in acidic plating baths and the thickness of plated tin layers for respective steps so as to improve the uniformity of the initially deposited layer.  
     CONSTITUTION: An electroplating process, where steel sheet 8 is fed stepwise into plural plating tanks which contain electroplating bath for tin in order to form tin electroplated layer, is divided into deposition step for the initial layer and a deposition step for the build-up layer . In the deposition step for the initial layer, an acidic tin-plating bath contg. 8W20g/l nonionic surfactant is circulated by a pump 7c from a tank 11 to a plating tank 9, where a plated layer of 0.3W1.2g/m 2  thickness is formed. In the deposition step for the build-up layer, an acidic plating bath contg. 1W3g/l anionic surfactant is circulated by a pump 7e from a tank 12 to plating tanks 10aW10e, where a plated tin layer of 1.6W10g/m 2  thickness is formed. Hereby steel sheet plated with tin having excellent corrosion resistance compared with that produced by the conventional method is manufactured.

Title: Electromagnetic relay
Inventor: YANO KEISUKE
IPC: H01H50/18
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To suppress dispersion of operating characteristics by forming a pushing projected part, which has a part of an arc with a diameter as same as the distance of opposed faces of a movable iron piece and a movable contact piece as the tip end face, in the front and the back faces of a card to be pushed by the movable iron piece. SOLUTION: A card 40 is rotated through a movable iron piece 30 by an electromagnetic block 20 installed uprightly in a base 10 and a contact mechanism 50 is driven. A first and a second pushing projected part 41, 42 are formed in one side of the card 40 and a third pushing projected part 43 at the position at the same height as that of the first pushing projected part 41 is formed on the other side of the card. The tip end faces of the first and the third pushing projected part 41, 43 are formed to be parts of an arc 45 with the diameter as same as the distance D between the opposed faces of a movable iron piece 30 and a movable contact piece 51. Consequently, even if the card 40 is shaken by chattering due to clearance W1-W2 between a joining reception part 15 of a base 10 and a rotation axis 44 of the card, shifting from pushing points is not caused.  As a result, since the card 40 is not brought into contact only with one side of the iron piece 30 and the contact piece 51, so that dispersion of operating characteristics can be suppressed.

Title: Ceiling-embedded type air conditioner
Inventor: NODA TOSHINORI
IPC: F24F11/02
Filed: 1988-05-30
Abstract: PURPOSE:To let an air blow-off at a blow-off angle substantially horizontal to a ceiling surface when the operation of an air conditioner approaches stationary state operation, and blow-off downward on slant, by computing an indoor thermal load and detecting an unbalanced temperature based on a radiation temperature of a floor or the like and a suction air temperature within a living space. CONSTITUTION:The surface temperatures of a floor surface and a desk are detected by an air suction detection means 19, an indoor thermal load computing means 22, and a radiation temperature means 20 around the floor surface. When the detected thermal load and the unbalanced temperature are all lower than the preset values, blow-off angle change over means control the blow-off angle so that the air may blow off downward on a slant. The air-conditioned air is adapted to be fed constantly into a living space in the early stage of operation commencement so that the air may reach a required temperature promptly. When the air approaches the preset temperature and blow-off air temperature change rate is minimized, a horizontal air blow-off flow is adapted to be generated in a non living space. Therefore, an occupant is immune to a direct contact of air blow-off flow so that the people may not feel discomfort and the indoor temperature distribution may be improved sharply as well.

IPC: G01N27/406
Filed: 1992-04-23
Abstract: PURPOSE:To smoothly promote balanced reaction so as to obtain stable outputting by making an insulation layer for covering a reference electrode surface to be porous. CONSTITUTION:As a solid electrolyte 2, a NASICON thin plate is used, for example, because either of an alkaline metal ion or alkaline earth metal ion can be utilized for conductive species. A reference electrode 3 is formed by printing a gold paste on one surface of the NASICON thin plate and baking it, while a detecting electrode 1 is formed by printing a gold paste containing Na2CO3 and baking it. Further, on one surface of the electrolyte 2 including the polar face of the electrode 3, a paste consisting essentially of alumina is baked to prepare a porous insulation layer 8. Thus, the electrode 3 intends to be exposed in a gaseous phase and the balanced reaction of CO2 and NaCO3 in the gaseous phase is promoted smoothly, resulting in obtaining stable outputting for a long period.

Abstract: PURPOSE:To keep a stereoscopic state consecutively even if an identification signal is interrupted momentarily by generating a signal representing the stereoscopic state at the output terminal of a OR gate when any output signal of 2-stage of shift registers is in the stereoscopic reception state. CONSTITUTION:When the output signal of the 1st stage 30 and the 22nd stage 31 of the 1st shift register 26 are a signal (a) and (b) respectively, the output signal of the 1st OR gate 29 keeps the H state and the display and the reception of the 1st system AM stereoscopic signal are attained by applying an output signal obtained at the 1st output terminal 38 to a display device and a switching circuit. When an identification signal is missing in a signal (c) shown in broken lines X and the output of a memory 22 goes to L, an output L is fetched to the 1st stage 30 of the 1st shift register 26 in response to a clock pulse C. Then the output of the 1st stage 30 goes to L as shown in broken lines at the t1 of the signal (d). On the other hand, since the output of the 2nd stage 31 of the shift register 26 keeps H, the output of the 1st OR gate 29 keeps H and the reception and display of the AM stereoscopic signal of the 1st system are continued.

Filed: 1988-05-30
Abstract: PURPOSE:To simplify the image forming optical system of a copying machine changing the image forming position on a photosensitive body according to copying magnification by moving leading-edge and trailing-edge light shielding members as required according to copying magnification. CONSTITUTION:As an image forming lens 3 moves in an optical axis direction according to copying magnification, the leading and trailing edges of an image on the photosensitive body 8 changed. In response to said change, a light shielding sheet winding roll 6 is turned and driven, and a leading-edge light shielding sheet provided with an L-shaped angle 4A of the prescribed bent part is moved according to magnification alone, while a trailing-edge light shielding sheet is moved according to magnification and copying sheet size. Thus, light is shield in the area where an original image is not projected. The image forming optical system is simplified because the lens 3 need not to be moved in a direction perpendicular to the optical axis according to copying magnification.
