Title: Powder molding device
Inventor: SUGIMOTO AOI
IPC: B22F3/035
Filed: 1987-02-13
Abstract: PURPOSE:To permit easy taking-out of a molding having projecting parts or recesses on the inside surface after compression of powder is completed by supporting a powder molding art where part of cores or punch is formed independent and is provided with the recesses or projecting parts in such a manner that said molding part can be moved in the direction perpendicular to the main axis of a press. CONSTITUTION:The powder molding A is packed into a cavity formed of a die 1, a lower punch 3, an inner core 5 and an outer core 4. An upper punch 2 is then inserted into the cavity to start compression and in succession, the die 1 and the cores 4, 5 are lowered together. The compression is completed when the upper punch 2 arrives at the bottom dead point and the outer core 4 descends down to a base plate 9. The die 1 is thereafter lowered further together with the inner core 5. A shoulder part 7'' thereof and a shoulder part 7' of the outer core 4 are engaged with each other and the core 4 is retreated in the axial center direction by a propulsion means 8 such as spring. The projecting parts 6 of the outer core 4 forming the recesses of the powder molding A' are thereby detached from the inside wall surface of the molding A' and the molding A' is easily taken out in the axial center direction.

Abstract: PURPOSE:To eliminate the presence of clearance between the edge of the electrode and the insulator film in the formation of the electrode by means of forming a photoresist film having a hole diameter thereof is larger than the electrode window following the etching of the window. CONSTITUTION:An insulator film composed of an SiO2 film 11 is formed on the main surface of an Si substrate 10 comprising multi-layers of p, n and n<+> conductivity type regions. Subsequently, a photoresist film 12 is applied on the film 11 and after the film 12 is partially removed by photoetching, a window 13 is provided for etching. The film 11 is removed by etching with the film 12 as a mask to form an electrode window. After the removal of the film 12, a photoresist film 15 for correction is applied again over the entire surface of the film 11. The film 15 is removed in the portion immediately above the window 14 to form an evaporation window 16 with a diameter larger than the window 14. Then, a conductive film 17 is applied on the film 15. The film alone is left within the windows 14 and 16 by removing the film 15 to form an electrode 18.

Title: Instantaneous hot water heater
Inventor: ENOMOTO MASANORI
IPC: F24D17/00
Filed: 1990-02-15
Abstract: PURPOSE:To keep a prescribed temperature of outflow hot water by opening a fuel gas control solenoid valve when the temperature in a tank falls below a set value and, at the same time, operating ignition means attached to a burner to perform gas combustion. CONSTITUTION:When very little hot water 21 of a degree at which a flow sensor 12 can not detect a water flow flows out, a particular reaction is not immediately generated. However, since water supplied from a feed pipe 10 circulates in a heat exchanger 7 as the water is at a normal temperature to be supplemented into a hot water storage tank 16, the temperature of hot water stored in the tank 16 gradually falls. When the output signal of a thermistor 17 in the tank 16 decreases to a set value, a motor-operated changeover valve 15 is changed over and supply water which has passed the heat exchanger 7 flows into the neighborhood of the top of the hot water storage tank 16. Then, a hot water circulating pump 18 and a combustion fan 9 are operated to generate circulating flows shown by arrows (g), (h), (b), (c), (i) and (j). Further, a gas solenoid valve 2 is opened with the delay of a very small time to operate an igniter electrode 5 and combustion is performed by a burner 4. Thus, the temperature of hot water is always kept within a set range.

Title: Lean-to roof
Inventor: SAITO EISUKE
IPC: E04F10/08
Filed: 1994-03-02
Abstract: PURPOSE:To stabilize the intensity of solar radiation by forming a lean-to roof by means of a dimming panel in which an organic solution for restraining the transmission of light by a temperature rise and returning to its original state by a temperature drop is sandwiched with transparent platelike bodies. CONSTITUTION:A dimming panel 2 is formed by sandwiching an organic solution 5 consisting of a solution containing a water-soluble high molecular compound, or a solution containing a water-soluble high molecular compound and a nonionic surface active agent with glass plates 4a, 4b. When the solar radiation is on the lean-to roof 1 consisting of this dimming panel 2 and the temperature of the panel 2 rises, the organic solution 5 becomes cloudy or is colored for restraining the transmission of light, and the amount of solar radiation is directly reduced. When the solar radiation diminishes and the temperature of the panel 2 drops, the organic solution 5 returns to its original state, and the restraint of light transmission is stopped and plenty of solar radiation is taken in. Thus, a person inside the lean-to roof can visually recognize the outside space for enhancing a feeling of release.

IPC: F27B21/10
Filed: 1979-03-20
Abstract: PURPOSE: To prevent a quality deterioration of sintered ore by spraying water upon a lower layer portion of a charged starting material layer on a pallet and controlling heat accumulation in the portion with heat of vaporization of the water when fine ore is sintered with a DL type sintering machine.  
     CONSTITUTION: Grate protecting bed ore 4 is laid on moving pallet 1 of a sintering machine, and blended starting material 5 for sintering is charged onto ore 4 in layer with drum feeder 7 and deflector plate 8. Feed water piping 9 and a plurality of spray nozzles 10 leading to piping 9 have been set at the charge accumulation starting point on pallet 1 or a little to the side of bed ore hopper 2 in the lateral direction of pallet 1, and water is sprayed from nozzles 10 upon a lower layer portion of material 5 on pallet 1. The water content of the portion is increased, and an excessive temp. rise in the portion due to downward draft is controlled by evaporation of the water to prevent the portion from lowering in gas permeability owing to overmelting and bonding. Thus, the resulting sintered ore is prevented from lowering in reduction powdering rate in a blast furnace.

Abstract: PURPOSE:To increase the output of an induction motor even when the motor has a small size by transforming a coolant into mists through a two-fluid spraying nozzle and supplying the mists into the induction motor on cooling air produced by an air blower. CONSTITUTION:When an induction motor is operated, an air blower 6 is simultaneously operated and cooling air is discharged from the motor after passing through the motor. While the cooling air is passed through the motor, a coolant solenoid valve 11, high-pressure solenoid valve 12, coolant pump 13, and air compressor 15 are operated by means of control signals 11a, 12a, 13a, and 15a sent from a controller 18 and mists 10a are injected from a two-fluid spraying nozzle 10 and supplied to the surfaces of heat generating bodies in the motor, namely, a stator iron core 2, rotor iron core 3, stator coil 2a, and rotor coil 3a on the cooling air A produced by the air blower 6. When the mists 10a come into contact with the surfaces of the heat generating bodies, the mists 10 generate heat and their temperature rises. However, since the heat generating body is further cooled by the latent heat of evaporation of the mists 10, the output of the induction motor can be increased.
