Title: Pot type burner
Inventor: NAGANO HISASHI
IPC: F23D5/04
Filed: 1986-04-23
Abstract: PURPOSE:To make it possible to have a stable combusiton for a long time even when a heavy crude oil is used for fuel by providing circumferentially a plurality of fuel supply openings on the lower circumferential wall of a pot at an equal distance among them and a change-over device which changes over fuel supply openings. CONSTITUTION:Fuel supply to a fuel storage section 5 which is located at the bottom section of a pot 1 is made from either a fuel supply opening 3A or a fuel supply opening 3B by changing over automatically or manually valves 31 and 32 periodially. With this arrangement the coke formed and piled near the fuel supply opening 3A at the bottom section of a pot 1 while the fuel is supplied from the fuel supply opening 3A, is burned and consumed by the combustion heat of a first combustion chamber 10 and part of the air introduced for combustion during the fuel supply from the fuel combustion opening 3B opposite to the opening 3A due to change-over of the fuel supply. It is, therefore, possible to maintain stable combustion for a long time even if heavy crude oil is used for fuel.

Filed: 1995-04-18
Abstract: PURPOSE: To surely make recorded data correspond to a geodetic system by providing a recording means recording position information converted by a data conversion means based on the geodetic system selected by a geodetic system selection means. CONSTITUTION: A CPU checks whether a geodetic system selection mode is set. In the case the geodetic system selection mode is set, a mark 'A' expressing the geodetic system is flickered in order to show that the geodetic system mode is set. By setting the geodetic system to a Tokyo geodetic system, for instance, from a key input part 35, a data conversion part 40 in the CPU data-converts position information obtained by a GPA reception part 32 based on the coordinate system of the Tokyo geodetic system. Then, the converted position information data and the geodetic system information are displayed on an LED display part 34. Next, after driving a shutter, the converted position information data and geodetic system information, etc., are imprinted on the recording area of film from an imprinting LED 37a synchronizing with a film feeding signal.

IPC: H01L27/04
Filed: 1994-04-28
Abstract: PURPOSE:To stabilize the final resistance value of a polycrystalline silicon resistance element by introducing a halogen into the polycrystalline silicon resistance element while controlling them accurately. CONSTITUTION:If, for example, fluorine is introduced prior to the penetration of hydrogen into a polycrystalline silicon resistance element, the coupling hands of the silicon atoms 11 occurring along the grain boundary face are terminated by fluoric atoms. The quantity of introduced fluorine can be controlled accurately by ion implantation method or the like, so the change of the resistivity of the polycrystalline silicon resistance element can be controlled accurately. The resistivity of the polycrystalline silicon resistance element controlled accurately by the introduction of fluorine is stabilized, and it no longer changes inadvertently by the penetration of hydrogen. Hereby, the final resistance value of the polycrystalline silicon resistance element can be controlled accurately.

Title: Elevator
Inventor: YOKOTA FUMIO
IPC: B66D1/00
Filed: 1990-04-09
Abstract: PURPOSE:To prevent a wire wound around a winding drum from being slackened by adjacently placing a plurality of rollers on a passage of a wire connecting between the winding drum and an elevating unit and winding a bent wire around the rollers. CONSTITUTION:In an elevator, even if there is slack in a wire 6 which is hung at the time of an elevating unit 2 elevating, the slack is suppressed by three adjacent rollers 11 to 13 and is not transmitted to a winding drum 4. Therefore a wire 6 wound around the winding drum 4 will not be slackened. Thus even if tension due to the elevating unit 2 is applied to the wire 6 when the wire 6 is wound up, the wire may not bite into the wire 6 resulting in no possibility of failure in unwinding. Since the wire 6 is wound with resistance force of the three rollers 11 to 13 as tension of the wire 6 at the time of winding, the wire can be wound without slack. The resistance force in a group of rollers 11 to 13 against the wire 6 is approximately 400g, so that the elevating unit 2 having a weight exceeding this force is not supposed to drop by its own weight.
