Title: Galvanic battery type gas sensor
Inventor: FUJITA YUUKOU
IPC: G01N27/404
Filed: 1983-11-14
Abstract: PURPOSE:To reduce variation in the sensor output associated with temperature changes by integrally laminating a porous nickel plate, a porous resin adhesive layer and a carbonfluoride resin film. CONSTITUTION:For example in the case of an oxygen sensor, the positive pole 1 shall be a platinum plate while the cathode 2 lead, an aqueous solution of acetic acid or the like for the electrolytic liquid 3 and the positive electrode 1 is provided with a gas transmitting film 5. The transmission film 5 is produced as integral film by laminating a porous nickel plate 6 as the first layer, a porous adhesive layer 7 made of a ethylene tetrafluoride-propylene hexafluoride copolymer or a mixture of this and an ethylene tetrafluoride-ethylene copolymer as the second layer and a carbonfluoride resin film 8 with the porosity of less than 20% as the third layer. The concentration of oxygen is detected from the resistance 11 between the positive pole 1 and the negative pole 2. This method can be used for a hydrogen sensor likewise. Thus, as the gas transmitting film 5 is reinforced by the porous nickel plate 5, there is limited variation in the sensor output associated with expansion and shrinkage due to temperature changes thereby enabling accurate detection along with a simple manufacture.

Abstract: PURPOSE:To increase an output voltage saturation magnetic field point for the earth magnetism or a magnetic field nearly as intense as the earth magnetism by supplying a pulse current to a magnetic body which is 10 - 50 mm long and obtaining an output voltage from winding. CONSTITUTION:When a driving pulse voltage Ei is applied from a power source 8 to the magnetic body 6 which is 10 - 50mm long to make a current flow, a voltage with a crest value corresponding to a component of an external magnetic field in the same direction with the magnetic body 6 is generated between both ends 9 and 10 of the detection wiring is developed between both ends 9 and 10 of the detection wiring 7. Thus, the output voltage saturation magnetic field point is increased for the earth magnetism or a magnetic field weaker than the earth magnetism and the relation between the magnetic field intensity and output voltage becomes linear.

Title: Spool case for bonding wire
Inventor: ASUKE TADAO
IPC: B65H49/38
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a spool case which holds a contained spool without touching it, enables spool attachment/removal with respect to a bonder regardless of the holder length, presence/absence of engaging means and the like, provides high spool-holding reliability, and easily maintains spool holding status. SOLUTION: A pair of engaging pieces 5 provided in a cover 2 hold a spool 100, so as to enable handling of the spool 100 without touching it. The spool- holding status is maintained by elastic engaging forces of the respective engaging pieces 5, and the status is not released unless the engaging pieces 5 are elastically deformed so as to be removed from a flange. Furthermore, the spool- holding status is maintained by engaging the engaging pieces 5 with the outer periphery of the flange, which does not interfere with a wire rolled around a spool body 101 and the inside of the spool body 101.

Abstract: PURPOSE:To eliminate the use of an air supply pressure gauge and reduce the cost of a device by controlling the number of revolution of an air supply fan and an exhaust fan by the degree of opening of a vane in a variable flow rate unit. CONSTITUTION:In cooling operation, in the side of an air conditioner the degree of opening of a cold/hot water valve 4 is changed and the amount of cold water flowing through a cold/hot water coil 2 is changed to keep air supply temperature at a predetermined value. Alternatively, in an indoor side indoor temperature is measured using indoor thermometers 8a-8b and the degree of opening of vane 8a-8b of variable flow rate units 5a, 5b is changed by indoor temperature adjusting units 7a-7b to change the flow rate of air blown off into the room and hence keep the indoor temperature at a predetermined value. For air supply pressure control, the degree of opening of the vanes 8a-8b of the individual variable flow rate units 5a-5b is provided from the indoor temperature adjusting units 7a-7b, and the number of revolutions of an air supply fan 3 is directly controlled based upon the degree of vane opening to keep the air supply pressure at a predetermined value.

Abstract: PURPOSE:To allow a turbine to be manufactured without need of strict air-tight structure by rotating a spin head for rotating matters to be dealt with by use of the turbine driven by compressed nitrogen gas. CONSTITUTION:After a wafer 3 for which exposure has been completed is made to position on a spin head 2, a lid 4 is closed and a cavity 17 is sucked by a suction pipe 18 to press and fix the wafer 3 to the spin head 2. Then, compressed nitrogen gas is supplied into a turbine casing 9 through a valve 13 to rotate a turbine impeller 10 and the spin head 2 via a shaft 7. Next, a developer liquid is sprayed onto the wafer 3 from a spray nozzle 5 and a chamber 1 for developing is evacuated through an evacuation pipe 6. A fixed part of a photoresist on the wafer 3 is solved by the developer liquid and removed. This allows the turbine to be miniaturized, without danger of flash ignition even in the inflammable atmosphere and need of application of strict air-tight structure to the turbine.

Title: Clothes drying machine
Inventor: YAGI KEIJIROU
IPC: D06F58/02
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To enhance drying efficiency and to shorten drying time by disposing an aperture having an opening/closing lid in a part of a blasting path for heating the air after condensing and removing moisture with a heater and feeding the air into a drying chamber, adopting a structure to automatically open the opening/closing lid and providing the outside of the opening/closing lid with a cover. SOLUTION: During the drying work of clothes, the hot air heated by the heater 7 is circulated and the moisture content (moisture) generated by the evaporation of the moisture content flows through a filter 11 and is condensed by a heat exchange fan 6. The air from which the moisture content is removed is refluxed through this circulation wind path into the drying chamber 42 of a drum. At this time, the drying degree of the clothes is detected by a humidity sensor, or the like. When a prescribed drying value is attained, a motor is activated and the opening/closing lid 17 is turned in a direction (left direction) where the aperture 211 is opened via an eccentric cam, or the like.  Part of the circulation wind path is changed in its direction by opening of the opening/closing lid 17 on the inner side of the outer cover 25 covering the aperture 211 to discharge the air outside the machine. Also, the outdoor air is mixed with the circulating air introduced into a vent path which is the circulation wind path.
