Title: 2-magnetic path type voice coil motor
Inventor: IKEDA FUMIAKI
IPC: H02K41/035
Filed: 1984-09-29
Abstract: PURPOSE:To reduce the inductance of a movable coil by providing a magnetic resistance unit at the axial neutral position of a center pole disposed at the space center formed by a yoke. CONSTITUTION:A 2-magnetic path type voice coil motor is composed of permanent magnets 1, 2 disposed symmetrically with respect to the upper and lower positions, yokes 3, 4, a center pole 5, a space 6 formed between the pole and the magnets, and a movable coil 7. In this case, a magnetic resistance unit made of a thin nonmagnetic material 10 such as plastic is formed at the axial neutral position of the pole 5. Thus, since the material 10 is inserted vertically in the midway of the magnetic path of the magnetic flux 11 formed by a current flowed through the coil 7, the magnetic flux 11 is weakened to reduce the inductance of the coil 7. Since the magnetic fluxes 8, 9 are in parallel with the material 10, they do not almost decrease.

Title: Water heater
Inventor: KOGA RIYOUICHI
IPC: F24H1/10
Filed: 1981-12-18
Abstract: PURPOSE:To widen the range of regulating flow rate, lower the surface temperature of a heat-transmitting surface of a heat exchanger and enhance reliability, by a method wherein a bypass passage provided with a pressure relief valve connecting an intermediate part of a heat exchanger and an inflow port or an outflow port to each other is fitted to a water heating passage. CONSTITUTION:In using a heater, when a flow rate regulating valve 4 is opened, a fluid to be heated starts to flow through a heating passage 1b, and when the flow rate exceeds a predetermined value, the pressure P in a heating passage 1 between a valve 4 and a heat exchanger 5 is raised to close a pressure switch 9. Then, an electric current is passed to a heating means 8, and the heat exchanger 5 is heated. When said pressure P is reached, the pressure relief valve 10 in a bypass passage 11 starts to open so that a part of the fluid is diverted into the passage 11. The quantity of the fluid diverted is markedly increased by only a small rise in the pressure P by the action of the relief valve 10. Accordingly, the overall flow rate through the heating passage 1b can be increased while maintaining the minimum rate of the flow to the heat exchanger, and a wide range  of regulating the flow rate can be obtained.

Abstract: PURPOSE:To uniformize a developer thin layer formed on the periphery of a carrier by supplying a developer to a porous thin plate in sliding contact on the periphery of a developer carrier and having the application of a voltage having the same polarity as the electrifying polarity of the developer. CONSTITUTION:The developer supplied into a housing 13 is stirred by a supplying roller 12, to be electrified to a negative polarity, and carried to a mesh member 14. When the developer is carried by the supplying roller 12 and reaches a region opposite to a developing roller 11, the mesh member 14 is electrified to the same polarity as that of the electrified developer, so that the developer repulses the mesh member 14, but the developer is pressed by the supplying roller 12. Therefore, the developer electrified to the negative polarity passes the mesh member 14 interposed between the supplying roller 12 and the developing roller 11. The developer passing the mesh member 14 is carried to a region abutted on a photosensitive body 20, by the developing roller 11. The developer is brought into sliding contact on the mesh member 14 during the carrying, so that the developer forms an uniform thin layer on the periphery of a urethane rubber 11b on the developing roller 11, while being sufficiently triboelectrified.

Filed: 1984-10-02
Abstract: PURPOSE:To provide suitably tapered connection holes uniformly by a method wherein a phosphorus silicate glass (PSG) film, an Si3N4 film, and a BSG film are laminated on a semiconductor substrate successively, a wet etching is performed on the BSG film using a photoresist mask, and a plasma etching is performed on the Si3N4 and the PSG. CONSTITUTION:A PSG film 6, an Si3N4 film 7 and a BSG film 8 are superposed on an Si substrate 5, and a photoresist mask 9 of pattern width W0 is provided. When an etching is performed on the BSG using shock absorbing hydrofluoric acid, the amounts of etching on the side face W1-W0 are remarkably small, because the etching speed of the BSG is extremely lower than that of the PSG, the Si3N4 has a very small etching rate, and the PSG located below the Si3N4 is never etched. Then, after the Si3N4 film 7 and the PSG film 6 are etched by performing an anisotropic etching and the resist 9 is removed, suitably tapered connection holes are obtained mainly on the BSG film 8, and the width of a connection part can be made small by providing an Al wiring 10. As the etching rate of the BSG is low for shock absorbing hydrofluoric acid, the control of taper can be performed freely and the connection holes can be formed uniformly.

When the vertical shafts 9, 10 are lowered down to specified height, a limit switch works and stops their lowering.  Thereafter, hoisted load falling preventive claws 11, 12 are slewed to the side of the hoisted load and are engaged with a lower surface part of the hoisted load.
