Title: Device for excluding dropped substance on conveyor belt
Inventor: SERIKAWA HARUYUKI
IPC: B65G45/12
Filed: 1987-04-28
Abstract: PURPOSE:To provide an increased life, by a method wherein a rolling member is situated on the support member for excluding a dropped substance, the exclud ing member is separated away from a conveyor belt, and the rolling member is rolled in linkage with movement of the conveyor belt. CONSTITUTION:A wheel 9 is mounted on a support member 4 for supporting an excluding member 8 through formation of a projected part, protruded in parallel to the extending direction of a conveyor belt 6 and formed in an L- shape in cross section. The wheel 9 prevents contact between the side edge of the conveyor belt of the excluding member 8 and the surface of the belt 6. This constitution prevents damage due to contact between the conveyor belt and the excluding member and enables provision of an increased service life.

Title: Treatment of septic tank sludge
Inventor: SUZUKI TAKAYUKI
IPC: C02F11/00
Filed: 1989-04-25
Abstract: PURPOSE:To obtain dehydrated cake having a low content of water by oxidizing the DO in an aeration tank under specified conditions and dehydrating cake. CONSTITUTION:The septic tank sludge 1 is introduced into the aeration tank 4 to be charged with oxygen-enriched air 3 along with return sludge 2, and the separated sludge is mostly introduced into the aeration tank 4 as the return sludge 2 and partly transferred to a concentration tank 8 as excess sludge 7. The concd. sludge 9 from the concentration tank 8 is introduced into a dehydration stage 10 and discharged as the dehydrated cake 11. The overflowing water 12 from the concentration tank 8 and the separated water 13 in dehydration can be discharged as it is, or introduced into the aeration tank 4. The aeration tank 4 is airtightly closed to prevent the outflow of the oxygen-enriched air 3 into the atmosphere. Consequently, the dehydrated cake is hardly decomposed and softened.

Title: Substrate device using non-eutectic solder
Inventor: NAOI MASAYA
IPC: H05K3/34
Filed: 1988-04-26
Abstract: PURPOSE:To prevent the generation of the rising phenomenon of a surface mounting part by using non-eutectic solder, the ratio of components of which is selected, so that a solidus curve and a liquidus curve do not coincide and mounting a surface mounting part onto a printed board. CONSTITUTION:A surface mounting part 1 placed onto specified conductive layers 6, 7 formed to a printed board 5 is fixed with pasty non-eutectic solder 10, 11, thus constituting a substrate device. A soldering device using a vapor- phase solder tank in which a heating temperature is easy to be adjusted is employed for fastening the non-eutectic solder 10, 11. When non-eutectic solder, the composition ratio of an alloy of which is selected, is used so as to be deviated from an amorphous point (p), the solidus curve La and liquidus curve Lb of the alloy do not coincide. When the alloy is composed so that the composition ratio is brought to Q, the temperature T1 of the solidus curve La and the temperature T2 of the liquidus curve Lb differ. Consequently, when the heating temperature is set at a proper temperature Tc between T1 and T2 in a first heating process, non-eutectic solder is brought to the state in which a liquid and a solid are mixed, a half-molten state. The surface mounting part is metallically bonded under the half-molten state.

Inventor: BUERUNAA FUAUPERU
IPC: F02D1/18
Filed: 1989-04-25
Abstract: PURPOSE: To enable an engine to rotate smoothly and reduce noise therefrom by having a closing pressure of a pressure maintenance valve to be smaller than a suction chamber pressure at idling. CONSTITUTION: A pressure control valve 1 and a pressure maintenance valve 8 are provided in a fuel injection pump.

Title: Sprue bushing structure for mold
Inventor: KOJIMA HISASHI
IPC: B29C45/28
Filed: 1984-05-23
Abstract: PURPOSE:To eliminate burden of nozzles by obviating the strain of sprue bush and molds by a method in which a larger-diameter tiered portion than the spherical face side of the sprue bush and an operating room for the tiered portion is provided. CONSTITUTION:When a nozzle 32 is contacted by the nozzle touch force and molten resin is injected and packed into a gate 27 and a cavity 3, a pressure of resin is generated. At the generating timing of the resin pressure, a pressure for the drawing direction acts on the tip face 24, and thereby at the generating timing pressure oil is acted on the operating chamber 10. It is thus allowed that the nozzle touch force is lessened, linear oil pressures from a tiered portion 14 are added to the linear resin pressures, and the large-diameter portion 11 can be worked as a piston. The small-diameter portion 12 can thus be worked as a rod according to the oil pressures to add linear pressures to the tip face 24.
