Patent JP-H02133742-A (JP)
Title: Air conditioning plant
Inventor: ISHIKAWA HARUO
IPC: F24F11/02
Filed: 1988-11-15
Abstract: PURPOSE:To certainly prevent dripping of moisture, which smears the floor, at the time of a fault in machinery or the like by stopping the air-conditioning operation when the outer heat exchanger of a unit is cooled close to the dew point. CONSTITUTION:During indoor cooling, the fall of the temperature of the inner heat exchanger 11 of a unit below the dew point causes the moisture contained in the indoor air to drip as dewdrops; but this raises no problem because the indoor unit 10 is provided with a means for receiving the dewdrops and draining the water thereunder. However, if the refrigerant flows into a unit-surface heat exchanger 13 owing to a fault in a three-way valve 14, threey-way valve motor 14a, or the like during the cooling operation, dew drips from the unit- surface heat exchanger 13 and may smear the floor. To certainly prevent the dripping of moisture which thus smears the floor, a panel-temperature sensor 16 is provided in a setup to process the signal therefrom by a control device 7 so that the compressor is stopped when the unit-surface heat exchanger 13 is cooled close to the dew point.

Title: Discharge lamp lighting device
Inventor: HIRATA HISAO
IPC: H05B41/282
Filed: 1990-10-29
Abstract: PURPOSE:To stabilize the power of a discharge lamp by converting the DC output of a DC converter into AC via an inverter so as to supply the discharge tube, and controlling the output of the converter so as to be constant power based on the detected results of the voltage and the current of the converter output. CONSTITUTION:The voltage and the current of a converter 6 output are detected by a voltage detector 7 and a current detector 8, and these detected signals are operated by an arithmetic circuit 9 so as to be sent to a PWM control circuit 10. Next, the signal is compared with a standard signal in the circuit 10 so as to PWM-control the converter 6 and control an output voltage. In this way, the output voltage decreases in the converter 6 when the impedance of a load discharge lamp 3 is low while it increases when the impedance is high, the output is kept constant within a reversible range, regardless of the impedance of the discharge lamp 3. It is thereby possible to stabilize the power of the discharge lamp 3 by a simple circuit configuration and prevent deterioration owing to an excess input.

Title: Electric vacuum cleaner
Inventor: IGARASHI AKIRA
IPC: A47L7/00
Filed: 1989-11-06
Abstract: PURPOSE:To exterminate the harmful microorganisms within a prescribed time and prevent a motor-driven blower from being burnt by installing a temperature controller which closes a heating air passage at the first temperature where the harmful microorganism can be exterminated and opens the passage at the second temperature which is higher than the first temperature and where the motor-driven blower is not burnt, into the heating air passage. CONSTITUTION:Below the temperature in an air passage of 50 deg.C, an outside air taking inlet 12 is closed by an outside-air shielding plate 40 of a temperature controller 35, and the outside air and the air in the air passage are cut off. The body side joint 33 of a hose 31 and a connection port connection part 30 are connected with an exhaust port 19 and a suction port 5, and a motor-driven blower 13 is driven to allow the air in the air passage to return- flow through the hose 31, dust collecting chamber 6, motor-driven blower 13, and a body case 3, and the temperature is raised. When the temperature in the air passage reaches 60 deg.C, the outside air shielding plate 40 shifts according to the contraction of a spring 38 made of shape memory alloy, and the outside air shielding plate 40 deflects from an outside-air taking inlet 39, and the outside air intrudes into the air passage. When the temperature lowers to 50 deg.C or below, the outside air is shielded again. When these operations are repeated over 3min., and the temperature is kept at 50-60 deg.C, the harmful microorganisms such as ticks can be exterminated.

Title: Concrete wall penetration piping
Inventor: UCHIDA MITSUHIKO
IPC: G21F3/00
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To reduce construction cost by preventing the break of piping or concrete. SOLUTION: Regarding a concrete wall penetration pipeline 1a led through a radiation shielding concrete wall 4 such as the cell of a reprocessing plant, the portion of the pipeline 1a buried in the concrete wall 4 is bent as angled and a cushion and insulation material 2 is wound around the portion of the pipeline 1a to the prescribed thickness. In addition, a waterproofing layer 3 is formed around the cushion and insulation material 2. As a result, the cushion and insulation material 2 restrains heat transfer from the high temperature piping 1a to the concrete wall 4, thereby restraining the temperature rise of the concrete wall 4. Also, the cushion function of the cushion and insulation material 2 acts to absorb the thermal elongation of the high temperature piping 1a, thereby preventing the occurrence of thermal stress.  The waterproofing tape (waterproofing layer) 3 also prevents water moisture contained in ready- mixed concrete to enter the cushion and insulation material at the time of concrete placement, thereby preventing a drop in cushion and insulation function.

Filed: 1994-10-31
Abstract: PURPOSE: To rapidly, easily customize fabrication of a plastic member having an indication by forming an etchable material on a contrasting surface, etching the layer with a prescribed pattern, exposing the contrasting surface and forming a graphics face in a mold. CONSTITUTION: In the method for fabricating an in-mold graphics, the in-mold graphics 10 includes a hardcoat layer 11 formed on an etchable material 12, a contrast surface 13 and a plastic 14. With regard to etching utilizing a laser beam, as the etchable material 12 absorbs the beam and burns, the etchable material can be removed. As different colors absorb or reflect different quantity of the beam one another, the beam can etch different layers selectively according to the kinds of the colors. For example, in a structure having a first layer 11 of hardcoat, the colors of a second layer 12 and a third layer 13 are black and white respectively, the beam are absorbed by the clack layer and hardcoat and black layers are burned. The third white layer 13 do not absorbs the beam and has no influence.

Title: Rotor of induction motor
Inventor: TAKAHASHI MIYOSHI
IPC: H02K17/16
Filed: 1986-12-05
Abstract: PURPOSE:To eliminate the skin effect by which the current concentrates to the outside diameter section in conductor bars and to prevent the increase of the high frequency resistance, by doing away with the flux across the rotor groove section. CONSTITUTION:A rotor 1 is composed of a laminated iron core 2, conductor bars 3, a rotor shaft 4, etc. On the outside diameter of the laminated core 2 grooves 5 are circumferentially provided at predetermined intervals, while the conductor bars 3 are embedded axially. The conductor bar is composed of a nearly integrally formed composite material with good conductive material 7 such as copper, aluminium, etc., interposed between ferromagnetic force lines 6 by a diametrically long fibrous iron, etc. Since a non-magnetic good conductive material 7 is interposed between steel wires 6 in the direction of circumference theta, magnetic permeability is low, but it is high in the direction of diameter r. Flux phi therefore flows almost in the direction of diameter and not in the direc tion of circumference, so that skin effect is found small. Moreover, as magnetic path is created in other than core teeth section 8, the efficiency is hence im proved.

Title: Surface mount semiconductor device
Inventor: KAWAHARA YOSHITOKU
IPC: H01L23/50
Filed: 1990-10-26
Abstract: PURPOSE:To enhance soldering efficiency by bending upward the tip of an outer lead wire which leads out from a sealing resin body with respect to the mounted side. CONSTITUTION:A tip 2' of an outer lead wire 2 which leads out from a sealing resin body 1 is bent upward at an angle of 90 deg. against the mounted side. Therefore, solder 3 climbs up toward tip 2' of the outer lead wire, which increases the coating weight of solder. Even when the tip 2' of the outer lead wire is bent, say, at 90 deg., 180 deg. or 60 deg., it will be possible to obtain similar coating weight of solder. This practice is applicable to even I type outer led wires in addition to the L type outer lead wires. The tip of the outer lead wire 2 can be bent upward against the mounted side, which makes it possible to enhance soldering efficiency during mounting operation.
