Title: Manufacture of resin mold
Inventor: NOZAKI MITSURU
IPC: B29C39/26
Filed: 1987-12-25
Abstract: PURPOSE:To obtain a resin mold provided with mold releasability, surface smoothness and heat resistance, by a method wherein the title resin mold is formed from a cured resin composition comprised of a mixture of a 98-70wt.% liquid thermosetting epoxy resin composition and silicone resin powder. CONSTITUTION:A resin mold is manufactured by arranging a composition obtained by mixing and dispersing uniformly a 98-70wt.% thermosetting epoxy resin composition which is liquid at a temperature of 100 deg.C or lower and 2-30wt.% silicone resin powder on a model surface and curing the same. In this instance, when loads of the silicone resin powder is less than 2wt.%, mold releasability becomes insufficient and when the silicone resin powder is used by exceeding 30wt.%, viscosity is increased and removal of bubbles through a dispersion mixture is difficult.

Filed: 1987-12-24
Abstract: PURPOSE:To provide an air conditioner which has a large range of operation by providing a bypass circuit through an electronic expansion valve which is a flow rate control device between an accumulator and the suction section of a compressor. CONSTITUTION:During the room cooling and room heating operations, an accumulator 4 is operated in the state of storing a coolant, and the coolant returning to the state of two phases is separated into a liquid phase part and gas phase part, and only the coolant in the gas phase is sucked from the suction pipe of a compressor 1. And, the coolant in the gas phase passes through a bypass circuit 9 which is provided at the liquid storage section of the accumulator and its smaller part flows into the suction pipe of the compressor 1, and the coolant in gas phase with a little of liquid phase mixed is sucked into the compressor 1. The amount of the returning liquid is controlled by an expansion valve 11 which is provided at the bypass circuit 9. At a control device 18 the discharged super-heat is controlled and at the same time of compressor 1 is controlled by setting its operation frequency on the low side so as to reduce the capability of the compressor 1 when the temperature of the discharged coolant is over a specified temperature. Accordingly it is possible to return a proper liquid coolant to the compressor and prevent faulty lubrication due to backing of the liquid coolant and an abnormal rise in the discharge temperature.

Title: Combustion apparatus
Inventor: NAKATANI KAZUTO
IPC: F23D3/10
Filed: 1987-12-24
Abstract: PURPOSE:To suppress sudden deterioration of the exhaust gas in quality and improve the combustion characteristics so as to widen the adjustability range of the combustion by providing, besides a sluice positioned on an outer casing opposite to an outer flame cylinder at its lower part, a second sluice over it and by making holeless part of the outer flame cylinder against which said sluice and the second sluice are positioned. CONSTITUTION:The unburnt gas which as leaked outwardly of an outer flame cylinder 7 is drawn into the combustion chamber through air holes in the outer flame cylinder 7 by virtue of a second sluice 22 which is positioned over a sluice 21 and with a certain gap from the outer flame cylinder 7. Most of the unburnt gas containing CO, having a part leaked inwardly of an inner flame cylinder 6 and in part outward of the outer flame cylinder 7, flows back into the combustion chamber 8 and burns so that the exhaust gas from the combustion can be maintained satisfactory in quality for the adjustment of the combustion in a wide range. Since the outer flame cylinder 7, to which the throttle 21 and the second throttle 22 face, is made holeless in part, large quantities of air flow in through these throttles. Therefore, the generation of a luminous flame representing an incomplete or unstable combustion is prevented in the combustion chamber 8 while the combustion is rendered free of a noise of combustion or wavering flame which would be caused by air holes. Thus the combustion can be stabilized.
