Title: Air conditioner
Inventor: NEGORO KOICHI
IPC: F24F11/02
Filed: 1986-01-30
Abstract: PURPOSE:To be able to continue a stable operation by controlling the switching of a selector valve and the operation of a blower and a compressor with a temp. controller and a humidity controller. CONSTITUTION:When an operation switch SW is turned on, an electro-magnetic contactor 52F is excited and a motor MF for a blower 6 is operated. When suction air in an evaporator 7 has higher humidity and temp. than specified values, a motor MC for a compressor 1 is operated. When air temp. in a room is lowered to below a specified temp., a temp. controller 14 detects the condition to cause condensation at both condensers 4 and 8. When the air temp. in the room is gradually increased and exceeds a specified temp. the operation is switched over to the operation shown by the solid line arrows. When humidity reaches below a specified value before the air temp. in the room exceeds a specified temp., the motors MC and MF are stopped. When the air temp. in the room is gradually reduced and reaches a specified temp., a contact 23 RL in a temp. controller 15 is closed. As a result, a large quantity of refrigerants stored in the condenser 8 are sucked up into the compressor 1 through a bypass route 16 and then discharged. Thereby, the frequent switching of the selector valve and the repeated operation and stopping of the blower are eliminated to make the occurrence of troubles difficult.

Abstract: PURPOSE:To prevent vibrations and disturbing noises from generating by the movement in a thrust direction of each shaft, by pressing the end parts of a feed roller rotary shaft and a carriage guide shaft into contact with an elastic side pressure plate provided outside a frame side plate. CONSTITUTION:Elastic side pressure plates 41A, 41B both made of elastic material are fixedly provided outside the opposite side plates of a frame 1 (only the side of the pressure plate 41A is shown in the drawing). Protrusions 42A, 42B are formed in each of the elastic side pressure plates 41A, 41B at the positions corresponding to an axial center of a feed roller shaft 21 and a guide shaft 4 inside the plate, respectively. Since the force acting in the axial direction of the carriage guide shaft 4 is larger than that of the feed roller shaft 21, the width of a part of the side pressure plates 41A, 41B to which the end of the carriage guide shaft 4 is pressed in contact is made smaller than that of the part thereof where the feed roller shaft 21 is in pressed contact, so that the former is much more influenced by the effects of the elasticity. Thus, the rattlings in the axial direction of each shaft can be restricted, thereby to prevent the generation of vibrations and abnormal noises.

Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To effectively remove org. matter and metallic contaminant by oxidative power and remove particles by ultrasonic vibration by impressing the ultrasonic vibration on pure water which is mixed with ozone and has oxidative power and executing washing by the washing water. SOLUTION: The pure water mixed with the ozone (ozone water) is filled in a washing tank 41 and the wash is immersed therein. The ultrasonic vibration generated from a vibration section 42 installed at the bottom of the washing tank 41 is transmitted into the pure water. The particles on the surface of the wash are removed by the ultrasonic vibration and the org. matter and metals are removed by the oxidative power of the ozone water. The washing tank 41 is made of a metal and a passive film of Cr2 O3 is formed on the inside surface thereof. The occurrence of the oxidation deterioration by the ozone water is prevented by the passive film and since the washing tank 41 is made of the metal, the vibration from the vibrating section 42 is effectively transmitted from the plane of the washing tank 4 to the ozone water.

Title: Fingerprint image pickup device for fingerprint collator
Inventor: KANARI MITSUSHIRO
IPC: H04N1/107
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized and inexpensive fingerprint image pickup device by composing this device of a rectangular image pickup slit provided on a measure table, a mobile body provided parallelly with the image pickup slit and a linear image sensor provided at the image forming position of the image pickup slit, etc. SOLUTION: Light emitted from a linear light source 18 is made incident on a prism 20 after its optical path is changed on a reflection plate 19. The upper face 22 of the prism satisfies full reflection conditions and the light is emitted again from the prism 20, passed through a Selfoc lens array 24 after the change of optical path on a reflection plate 23 and caught by a linear image sensor 25. When the ridge line of fingerprint touches the reflection plane 22 in the state of placing a finger 26 on the upper face 22 of the prism, the full reflection conditions are disordered and light gets out of the prism. Since the section of fingerprint excepting the ridge line is fully reflected as it is, the sharp image of fingerprint appears. Thus, since a one-dimensional image is handled in the case of dealing with a two-dimensional image and the optical path is shortened, cost can be reduced and the device can be miniaturized.

Abstract: PROBLEM TO BE SOLVED: To permit the maximum utilization of the space of a room without hindering the use of the room and eliminate the danger of generating fire by a method wherein a surface type heat generating body, having self temperature control function, is provided on a surface faced to the inside of the room. SOLUTION: A required heating instrument is obtained by bonding a surface type heat generating body 2, having self temperature control function, to the surface part of a floor material 1 or a surface part faced to the inside of a room through an aluminum foil 3. The surface type heat generating body 2 is provided with a heat generating layer 12, having flexibility, on the surface of a substrate sheet 11 and is formed so that an electric current is conducted through the heat generating layer 12 and heat is generated when the heat generating layer 12 is excited through a wire 13, buried into an insulating layer 14, while far infrared rays are emitted from the heat generating layer 12 due to the heat generation of the same.  On the other hand, the heat generating layer 12 is formed so that the temperature of the heat generating layer 12 is increased and the material of the heat generating layer 12 or polyethylene glycol is inflated whereby intervals between conductive carbon particles are widened and the resistance of the heat generating layer 12 is increased thereby making the conduction of the electric current hard and preventing the overheating of the heat generating body 2.

Abstract: PURPOSE:To reduce a concentration of nitrogen oxide in burnt exhaust gas by controlling a mixed ratio of burnt exhaust gas to a fresh air with judgement on oxygen concentration of mixed gas of burnt exhaust gas and a fresh air. CONSTITUTION:A fresh air necessary for burning is sucked in from a waste pit 15 and heated up to about 150 deg.C by a steam type air preheater 18 via a primary duct 19 and then to about 230 deg.C by a gas type preheater 9.

When burnt exhaust gas is not mixed with a fresh air at a constant ratio, burning is checked. As a counter measure for this, a mixed ratio of burnt gas to fresh air is controlled in order that mixed oxygen concentration of oxygen concentrations in fresh air and burnt exhaust gas may not be kept under an index value (18%).
