Title: Developing roller and developing device provided with the same
Inventor: SAKIDA YASUSHI
IPC: H01F7/02
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a developing roller and a developing device capable of effectively preventing the sticking of carrier. SOLUTION: This developing roller is provided with a rotatable non-magnetic sleeve and a fixed magnet body having plural magnetic poles and arranged in the sleeve. The plural magnetic poles include a developing principal pole N1 for supplying developer to a developing object, an upstream-side magnetic pole S1 positioned on an upstream side in the rotating direction of the sleeve as seen from the pole N1 and a downstream-side magnetic pole S2 positioned on a downstream side therein. The tangential direction component Bθ of flux density on the surface of the sleeve has peak values at a rotational angle position between the poles S1 and N1 and at that between the poles S2 and N1, respectively, and is nearly flat near the peak values.  Thus, the holding power of toner and carrier in a developing area is completely secured, and the carrier is effectively prevented from adhering to a photoreceptor.

Title: Work execution method of ship's bottom-shaped heat insulated foundation
Inventor: NOMURA YUKINOBU
IPC: E02D27/01
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to construct with in a short period of time a heat insulated foundation which may be used also as a heat storage body by assembling expanded plastic plates in a ship bottom shape, arranging and assembling reinforcement rods and molding boxes for a foundation beam portion and a foundation slab portion, and depositing concrete. SOLUTION: Expanded plastic plates 1 are assembled in a ship's bottom shape on the ground. Next, reinforcement rods 4a, 4b for a foundation beam portion and reinforcement rods for a foundation slab portion, and molding boxes 5 are assembled. As concrete is deposited, a ship bottom-shaped, heat-insulated foundation is formed in which heat insulating material and concrete are united into a single body. Finally the molding boxes 5 are removed, earth filling or earth banking is made as required on the outside peripheral portion of the foundation. Therefore, the concrete surface opposite the indoor side is completely covered with heat insulating material and is not exposed directly to the elements or ground moisture. Since the entire indoor side is made of concrete as a heat insulated structure, the temperature is kept relatively constant throughout summer and winter. Thus, heat insulated property and heat storage property are improved.

Title: Multichannel photocoupler
Inventor: KOBAYASHI TAKEO
IPC: H01L31/12
Filed: 1990-10-19
Abstract: PURPOSE:To supply a voltage to photodetectors of all channels from one collector terminal and to delete the number of terminals at a photodetector side by commonly using the collector terminal of the photodetector side of each channel of a multichannel photocoupler. CONSTITUTION:All photodetectors 2 made of phototransistors are placed on one collector terminal 3 as pairs with light emitting elements 1 placed on cathode terminals 5 independent at respective channels. Each channel is so shielded with each light shielding outer resin 9 as not to be affected by the influence of the light emitted from other channel. Thus, power is supplied to the terminal 3 thereby to supply the same voltage to all the emitting elements. Since the terminal 3 heretofore necessary to each channel may be one in one package, the collector terminals can be deleted. Further, the profile of the package can be reduced by about 2/3 per one channel.

Title: Light receiving unit
Inventor: FUJIWARA SUSUMU
IPC: H01L31/02
Filed: 1993-11-11
Abstract: PURPOSE:To reduce the mounting area and manhour by a structure wherein means for processing an electric signal from a light receiving chip and means for controlling based on the electric signal are mounted on a same lead frame as the light receiving chip at least which is sealed with a translucent resin. CONSTITUTION:A light receiving chip 2 for receiving an optical signal from a light emitting element and converting into an electric signal, and an element 5 for processing the electric signal and controlling based on the electric signal are mounted on a lead frame 1. They are connected electrically through a gold wire 3, for example, and sealed entirely with a translucent resin(e.g. an epoxy resin) 4 except the lead terminals. The signal processing/control element 5 is premolded with an opaque resin so that an external incident light causes no erroneous function. Since the light receiving chip 2 and the signal processing/ control element 5 are incorporated in one device, the mounting area and the manhour can be reduced.

Title: Hot water boiler using both gas and electricity
Inventor: KIYOU SHIYOUKEN
IPC: F24H1/28
Filed: 1989-10-30
Abstract: PURPOSE: To always keep a set temperature constant with a control box, by a method wherein gas and electric heat sources are provided in a combustion chamber arranged in a heating water tank provided inside a body, and a water pipe or a fuel pipe is arranged protruding from the combustion chamber to control the temperature of hot water in the heating water tank as specified. CONSTITUTION: After a heating water tank 2 is filled with water by a refilling water pipe 11, a graduation of a set temperature gauge 14 is adjusted to a desired temperature position. When a power source switch 18 of a control box 7 is operated, water is heated. At this point, the condition of ignition is checked by a flame detector 19 and a heat source is continuously supplied through a gas pipe 20 and a burner. Hot water temperature sensors 5 and 5' sense the temperature of the heating water tank 2 through wires 6 and 6' of the hot water temperature sensors to be transmitted to the control box 7. As the temperature of the hot water lowers by about 10-15 deg.C from the temperature on a set temperature gauge 14, the control box 7 is operated to supply a heat source, thereby always keeping the set temperature constant.

Abstract: PURPOSE:To enable the welding from the non-lining face side and to avoid the breakdown of the lining layer by performing the build-up welding of the flange part at the lining forming face side which is both parts or one part of a groove face. CONSTITUTION:An annular projection (flange part) 8a is formed by a build-up welding on the side end part of the lining forming face of the inner face of a through hole 7 by piercing the through hole 7 by performing a gas cutting on a base metal 1 first in the fitting. On the other hand, an annular projection (flange part) 8b is formed by the build-up welding similarly at the position equivalent to the lower end part on the outer peripheral face of a nozzle 2. Then, the nozzle 2 is inserted into the through hole 7 and arranged so as to a butt the flange parts 8a, 8b each other. The positioning of the nozzle 2 is performed with the tack welding of one part of the flange part 8a, 8b, thereafter the welding is performed from the pressure container outer face side, namely from the non-lining face side. It is finally welded and joined with the lining part 5 at both sides by patching a lining plate 6 on the nozzle lower end face. In this way, the welding from the non-lining face side becomes possible and the nozzle 2 fitting is performed without the breakdown of the lining layer.

Title: Filter paper for high-performance air filter and its production
Inventor: MATSUOKA HIROSHI
IPC: D21H27/00
Filed: 1994-11-17
Abstract: PURPOSE: To obtain a filter paper for high-performance air filters satisfying both performance of high dust-collecting efficiency and low pressure loss. CONSTITUTION: This filter paper for high performance air filter is obtained by adding inorganic substance fine particles having 0.3-5.0μm particle diameter in an amount of 10-100ppm based on binder weight to a binder to afford a binder liquid, impregnating a wet paper formed in papermaking part into the binder liquid and sucking excess binder liquid in -20 to -30cmHg gauge pressure. Since the inorganic substance fine particles having smaller particle diameter than the thickness of a grass fiber are contained into crossed parts formed by mutually crossing glass fibers together with the binder thereby, the filter paper can provide both performances of high dust-collecting efficiency and low pressure loss.
