Title: Paper feeder
Inventor: SEKINE NORIAKI
IPC: B65H1/12
Filed: 1991-09-18
Abstract: PURPOSE:To attain a stable feed of paper by holding constant the conveying force by a pickup roll with no influence by a number of sheets and size of recording paper. CONSTITUTION:In the case of feeding paper, when recording paper P loaded on a cassette bottom plate 3 is lifted by tension of a paper lift spring 4, first an upper surface of the recording paper P is brought into contact with a stopper roll 15, and a pickup roll 1, lowered down by receiving action of a torque limiter 14 by rotating a feed shaft 13, is brought into contact at a fixed pressure with the upper surface of the recording paper P. The applied pressure of the pickup roll 1 is set larger than lift force against the stopper roll 15 by the paper lift spring 4 so as to prevent an influence from being given to conveying force of the pickup roll 1.

Abstract: PURPOSE:To prevent occurrence of burrs in end plates by inserting fitting pieces smaller in length than fitting grooves projected on the end of blades into fitting mechanism of the end plates and caulking the edge of the end plates by a roller. CONSTITUTION:Fitting pieces 16, 17 of a blade 15 are inserted into fitting grooves 13, 14 of end plates 11, 12 from the outside in radial direction, and fitted by thrusting to the inside.

Title: Magnetic paste exhibiting sealing performance, conductivity and thermal conductivity
Inventor: NISHIKAWA TAKEO
IPC: H01F1/44
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To improve sealing performance, conductivity and thermal conductivity by forming a paste-type magnetic substance by mixing a small amount of 4-3 iron oxide, rare earth magnetic micromized powder, natural graphite and molybdenum disulphide with an alloy liquid of gallium, isodium and tin to form a paste-type magnetic material. SOLUTION: A seal of magnetic paste A substituting as oil seal, mechanical seal or the like of rotation movement is used for sealing device of gas, liquid and the like. A Ga magnetic paste A attracted around a permanent magnet B is put into a non-magnetic housing 2 and is fixed on a main body 3 to make it possible to rotate an axis 1 or the housing 2. In either case of rotation, since the magnet strongly attracts the Ga magnetic paste and is floated without contact sliding between solid bodies, rotation is smooth and light. If it is used for rotating electrode roll, it can prevent leakage of energizing material Ga inside and can be used for energization at the same time. Also, the contact resistance can be reduced, sliding can be performed with a light force and the durability can be largely improved by a lubricant such as graphite mixed in the Ga magnetic paste.

Abstract: PURPOSE:To obtain a polarizing element, polarizing plate and their production method with which an extremely fine pattern for polarized light can be drawn without requiring stretching of a polymer film, by forming a layer containing optically active molecules and forming a layer containing dichroic molecules in contact with that layer. CONSTITUTION:A layer containing optically active molecules which easily change the molecular axis with linearly polarized light is formed on a substrate, and the layer is irradiated with linearly polarized light including a wavelength range to be absorbed by the molecules in the layer. Then, by forming a layer containing dichroic molecules on the optically active molecule layer, dichroic molecules are oriented in the different direction. Namely, this invention includes the polarizing element and the polarizing plate having the layer containing optically active molecules and the layer containing dichroic molecules in contact with the first layer. Also, the invention includes the production method of the polarizing element and the polarizing plate by forming the layer having optically active molecules on the substrate, irradiating the layer with linearly polarized light, and forming the layer containing dichroic molecules on the optically active molecule layer. Since the polarizing element can be obtd. only by allowing dichroic molecules to be adsorbed to optically active molecules irradiated with linearly polarized light, a large-size polarizing element can be produced without requiring a stretching process.

Title: Air-cooled absorption cold/hot water device
Inventor: AIZAWA MICHIHIKO
IPC: F25B15/00
Filed: 1989-09-18
Abstract: PURPOSE:To keep always a stable combustion even if a pressure loss in an air-cooled absorber and a condensor is varied by a method wherein a combustion device is mounted outside a partition space comprised of an air cooled absorbing device, a condenser and an air-cooling fan. CONSTITUTION:A combustion equipment such as a hot regenerator 5 and a burner 9 or the like is separated from a negative pressure space 17 partitioned by a partition wall 16 with an air-cooled absorbing device, condensor and an air-cooling fan or the like. Accordingly, irrespective of a presence or non- presence of an operation of the air-cooling fan, the surrounding air of atmospheric pressure can always be used for combustion and then the combustion air can be discharged into a space having a surrounding air pressure. Since the part requiring a temperature keeping and a cold holding operation and an electrical component 20 are arranged outside the partition wall, there is no possibility that the stored parts are exposed to a flow of air, resulting in that a heat loss is also reduced and the electrical parts are arranged outside the partition wall and a disadvantage such as a reduction in insulation caused by an immersion of water is not generated.
