Title: Production of silver-impregnated active carbon
Inventor: OOKURA YUKIO
IPC: B01J20/20
Filed: 1980-07-07
Abstract: PURPOSE: To enhance the adhesiveness of silver to active carbon and to keep silver bleeding at a proper level, by having an easily water-soluble silver salt adsorbed onto active carbon, reacting the silver salt with the active carbon to form a difficultly water-soluble silver halide, and then injecting steam into the treated active carbon at a specified temperature.  
     CONSTITUTION: A silver salt easily soluble in water, e.g. silver nitrate or the like, is made to be adsorbed onto active carbon, and converted into a difficultly water- soluble silver halide in a conventional chemical reaction. Thereafter, steam is injected into the treated active carbon in a vessel at a temperature slightly lower than the melting point of the difficultly water-soluble silver halide, to produce silver- impregnated active carbon. Excess chlorine is desorbed from the active carbon by decomposition with the steam injection. Consequently, the product does not contain excess chlorine. As a result, the silver-impregnated active carbon excellent in the adhesiveness of silver to active carbon, which can be used for a long time while keeping silver bleeding at a proper level, can be obtained.

Title: Lamination type heat exchanger
Inventor: KUDO MITSUO
IPC: F28F3/04
Filed: 1989-04-14
Abstract: PURPOSE:To enhance a heat-exchanging efficiency by providing a channel at the bottom of the folded portion of a U-shaped refrigerant passage, the depth of the channel being deeper than the recessed part of each of heat transfer tube plates in a direction normal to an air stream, and the channel being formed in substantially parallel to the air stream. CONSTITUTION:Since a channel 22 is provided at the bottom of the folded portion of a U-shaped refrigerant passage 16 so as to be deeper than the recessed part 15 of each of heat transfer tube plates 11 and in substantially parallel to an air stream, more liquid refrigerant gathers in the channel 22 due to a centrifugal effect when the refrigerant takes a U-turn. The liquid refrigerant gathered in the channel 22 is made to flow toward the upstream side of the air stream along the channel 22 and flows directly into the flowing zone on the upstream side of the air stream in the U-shaped refrigerant passage 16, so that the liquid refrigerant is more supplied to the upstream side of the air stream where a thermal load is greater. As a result, an areal rate that is occupied by gas refrigerant, which does not contribute to heat exchange, on the flowing zone side on the upstream side of the air stream in the refrigerant passage 16 is decreased, and a heat-exchanging efficiency is improved. In addition, since a temperature on the tube wall of each of heat transfer tube plates 11 of a flat heat transfer tube 10 is high, the refrigerant flows more in the flowing zone on the upstream side of the air stream, where the viscosity of a freezer oil attached to the tube wall is low, whereby a flowing effect on the oil by the refrigerant is also improved. Accordingly, cooling performance is enhanced, the freezer oil is made easier to flow, and the return of the oil is improved.

CONSTITUTION:Since the source region 105 of an n-channel MOS transistor formed on the p type Si substrate 101 and the p<+> type source region 112 of a polycrystalline Si film pattern 110 laminated on the substrate 101 are in contact with each other via the defect layer 115, the rectification of a parasitic diode generated between those source regions 105 and 112 can be restrained. Therefore, in the case of operation of an inverter device by inputting voltage to a common gate electrode 104, the signal output can be outputted from a signal output electrode 120 between VDD and VSS at full-swing, accordingly the discrimination property for signal level can be remarkably improved.

Title: Poppet valve
Inventor: HARA YASUNORI
IPC: F16K31/06
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a poppet valve which is easily manufactured, and in which the pressure override value corresponding to the circuit in which it is to be incorporated is easily regulated by forming a downstream chamber inside a cylinder member as well as by providing a passage hole in the cylinder member, communicating the downstream chamber with an outport. SOLUTION: When the pressure at an inport 2 is elevated exceeding the cranking pressure preset by means of a spring 8, a poppet 6 moves while compressing the spring 8, and opens a seat part 5. When the seat part 5 opens, the pressure oil flows from the inport 2 through the seat part 5 into a downstream chamber 10, and then through a passage hole 11 formed in a cylinder member 9 to an outport 3. Such flowing determines a pressure override value corresponding to the fluid force of the poppet. The flowing direction is varied depending on the location, size or shape of the passage hole 11 formed in the cylinder member 9. The force acting on the poppet depends not only on the flowing direction but also on the flow rate or flow velocity. In addition, it may be regulated by the shape of the poppet.
