Title: Blowhole reducing method of aluminum alloy casting
Inventor: SUZUKI YOSHIHISA
IPC: B23K9/04
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To obtain a base material or a clad layer without defects such as blowholes in a comparatively simple method by melting a re-melting portion or a clad layer of a casting base material while high-energy waves are radiated, and controlling them to a directional solidification style in a manner that a solidification structure grows in a high-energy wave radiation direction in a cooling process. SOLUTION: When a clad part does not exist, a TIG torch 1 is fixed and a blowhole discharge 6 is formed by a directional solidification 5 so as to reduce defects of a base material 4. At that time, directional solidification is performed in a vertical direction. As another method, the directional solidification is done while the TIG torch 1 is moving. Additionally, after a groove is formed by machine processing or casting, a clad layer is formed and is re-melting treated. In this case, the TIG torch 1 is fixed to generate an arc and an enough molten pool is formed. Then, the arc is gradually weakened, and the directional solidification is performed in a direction from the base material to a molten pool surface by a cooling effect of the base material, so as to discharge the blowhole of the clad part.

An up-and-down driving device 11 is driven to lower the bonding head 10 by using an output signal from a processing part 13; it presses the semiconductor element 1 to an element-mounting face 5a via an anisotropically conductive film 7. A timer 21 inside the processing part 13 is actuated; the bonding head 10 keeps the temperature in the lower-end part at 190 deg.C and pressurizes the semiconductor element for about 30 seconds. The anisotropically conductive film 7 is heated and hardened; a bump 3 on the semiconductor element 1 is connected electrically to wiring pattern 6 on a substrate 5.

Title: Optical information recording medium and protective film for optical information recording medium
Inventor: UCHIDA MASAMI
IPC: G11B7/257
Filed: 1989-04-10
Abstract: PURPOSE:To obtain the disk which is stable to the thermal impact by repetition of recording and erasing or the change in the temp. and humidity of use environment by using a material formed by mixing SiO2 with AlN as 1st and 2nd protective layers. CONSTITUTION:A recording medium layer 3 to be irradiated with laser light is heated at >=400 deg.C although a very small spot of about 1mum is irradiated. The 1st protective layer 2 and the 2nd protective layer 4 are heated as well as the recording medium layer 3 heats up. The formation of the finer crystal grain size of the AlN is possible by mixing the SiO2 with the AlN having the drawback that the AlN is weak to a change in the use environment at the protective layer. The defect that the AlN is brittle is thus eliminated. The microcracks by the thermal impact are not admitted with the thin film formed by mixing the SiO2 with the AlN in such a manner even if the thin film is subjected to the repetition of the recording and reproducing. In addition, the disk is stable to the change in the temp. and humidity during the long-period use and preservation of the disk.

Title: Apparatus for detecting ink amount
Inventor: SUGIYAMA HIROSHI
IPC: B41J2/175
Filed: 1984-05-08
Abstract: PURPOSE:To make it possible to perform the display and control of an ink residual amount, by forming an ink tank so as to possess a structure moved up and down by the ink residual amount and providing a position detection means to said ink tank to detect the ink residual amount by the position of the ink tank in the up-and-down direction. CONSTITUTION:When an ink tank 1 is almost filled with ink 2, the resultant force of springs 5a, 5b is smaller than the total wt. of the ink 2, the ink tank 1 and a light blocking plate 6 and, therefore, the ink tank 1 is contacted with the upper surface of an ink tank guide member 3. At this time, the light blocking plate 6 is present at a position not blocking light to a light receiving element 8. The ink 2 is allowed to fly to a recording surface body 10 from a recording head 9 and the ink in the ink tank 1 is consumed and the residual amount of the ink 1 becomes slight before long. At this time, the resultant force of the springs 5a, 5b becomes larger than the total wt. of the ink 2, the ink tank 1 and the light blocking plate 6 and pushes up the ink tank 2 and the light blocking plate 6 rises to a position blocking light from a lamp 7 to the light receiving element 8. Because the quantity of light to the light receiving element 8 is different by a state, the ink amount of the ink tank is detected.

Title: Hot air heater
Inventor: TANZAWA SATOSHI
IPC: F24H3/04
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress generation of unburnt odor (unburnt gas) itself when operation is started or stopped by operating a fan and closing a hot air outlet when operation is started and opening the hot air outlet after inspection. SOLUTION: When the hot air heater is ignited, a backflow pressure is applied to a combustion cylinder 14 by the wind pressure generated from a fan 17 as shown by white arrows and heat generated during preheat of a vaporizer 13 is confined in the combustion cylinder 14 thus making uniform the temperature. Consequently, generation of unburnt gas is reduced when the hot air heater is ignited and generation of unburnt odor itself is suppressed. When a switch 18 is turned off or a stop instruction is delivered, a shutter motor 6 is driven while sustaining operation of the fan 17 thus closing a shutter 5 and thereby a hot air outlet 1.  Since a backflow pressure is applied to the combustion cylinder 14 by the wind pressure generated from the fan 17 similarly to the time when the hot air heater is ignited, generation of unburnt odor can also be suppressed when when the hot air heater is extinguished.

IPC: F24H9/00
Filed: 1984-05-07
Abstract: PURPOSE:To obtain high-temperature hot water in a short time as well as lessen the loss of heat by controllably switching the flow paths of incoming hot water. CONSTITUTION:A temperature sensor 12 is provided near the boundary between an always heating zone A and a bathing time heating zone B. When the whole of a hot water storage tank 1 is in unheated state, the low temperature is detected by the sensor 12, a three-way flow path switching valve 6 is switched to a top inflow tube 7 side, and the water in the lower part of the tank 1 is heated to a given temperature by a heat exchanger 4' and flowed into the top of the tank 1 to replace water with high-temperature hot water in the heating zone A. In the case of the bathing time heating, where temperatures higher than a given temperature are detected by the sensor 12, the zone A is judged to be filled with high-temperature hot water, the valve 6 is switched to an intermediate inflow tube 8 side, and heated water is flowed into the heating zone B by a distributer 2' to replace water with the heated water. When temperatures lower than a given temperature are detected by the sensor 12, heated water is flowed into the top, the high-temperature condition of the zone A is confirmed by the sensor 12, and the valve 6 is switched to the tube 8 side to heat up the zone B in the same way.
