Title: Chitosan preservation
Inventor: MITA NORIKO
IPC: A61K31/715
Filed: 1994-01-27
Abstract: PURPOSE:To keep stable quality of chitosan for a long time, by sealing chitosan in a container made of a packaging material with moistureproofness and gas- barrier performance. CONSTITUTION:Chitosan is preserved in a container made of a packaging material with moistureproofness and gas-barrier performance. The moisture permeability of the packaging material is to be 0-3.0g/m<2>.24h.atm and the oxygen permeability is to be 0-140-cc/m<2>.24h.atm. The packaging material is to be an aluminum based film and the chitosan is to be a product passed 32-400mesh. When a container with a cap is used, the cap part is to be tightly closed with a tape, and when a package with a film such as an aluminum vapor deposition film, an inner bag made of polyethylene, etc., preferably with an outer bag of an aluminum vapor deposition film. It is preferable to use in combination with a deoxidizer or desiccant in the chitosan preserver, or to replace the gas in the container with nitrogen gas. Thus, even if the chitosan is kept under a high temperature and high humidity condition, quality degradation such as viscosity rise is prevented and stable quality is kept for a long time.

Abstract: PURPOSE: To provide a facing frictional material which is excellent in its wear resistance and μ-V characteristics. CONSTITUTION: A frictional material is prepared by forming a frictional layer including the frictional material and organic binder of polyamidoimido group resin, on the surface of a metallic core plate. Three kinds of carbon fiber, alumina fiber and aramido fiber are used together as the frictional material and the contents of the frictional material and resin are respectively set to 30-60 and 40-70, in weight %. The entanglement structure of strong three- dimensional fiber is formed by excessively mixing a fiber kind by the combination of different fibers, and also a clearance through which oil can be moved is formed. The carbon fiber and the aramido fiber effectively function to improve the strength of the entanglement structure, and the alumina fiber effectively functions to stabilize the coefficient of friction.  The polyamidoimido group resin can be sufficiently strongly fix the fiber kind of the frictional material, and also excellent in its adhesiveness to the core plate and heat resistance.

Title: Device and method for classification ofbarrel abrasive materials and workpieces
Inventor: KAMEOKA MASANAO
IPC: B24B31/16
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a technology whereby both barrel abrasive materials and workpieces can be classified even if their specific gravities are larger than the specific gravity of a liquid in a classification method for barrel abrasive materials and workpieces utilizing the liquid. SOLUTION: A classification device is provided with a first tank 5 which stores a mixture of barrel abrasive materials and workpieces and a second tank 6 which collects the barrel abrasive materials or workpieces selected from the mixture. Also it is provided with a liquid flow generating device which generates a liquid flow in a specified direction in order to immerse the mixture into the liquid in the first tank 5 and move either the barrel abrasive materials or workpieces from the first tank 5 to the second tank 6. Then, for example, a process is performed to move the barrel abrasive materials or workpieces from the first tank to the second tank by a three-way liquid flow.  Next the generation of liquid flow in the first direction is stopped, and the agitation of the mixture accumulated at one end of the first tank is promoted by only the liquid flow in the second and third directions. These processes are repeated so as to separate the barrel abrasive materials from the workpieces completely for classification.

Abstract: PURPOSE: To capture gas in a bell and thus prevent lowering of the grab in its function during grasping an object by coupling a slide via in a bell-shaped release end part via an airtight elastic member, and a grasping means displacing in the radial direction through its displacement in the axial direction. CONSTITUTION: The lower part of a tubular body 2 constitutes a bell 16 released in its lower end, and an annular support piece having a slot in the longitudinal direction is stayed in the inner part thereof. Each grasping finger 20 is pivoted at the horizontal shaft 21 provided on the slot, each of which has a lower grasping part 20a to then be engaged with the groove 23 of an aggregate head part 15 at the grasping position. The finger 20 is formed with inclined faces 25a, 25b, and the slide 3 is formed with inclined faces 24a, 24b in the upper and lower parts of the recess 24. Through an interaction of these inclined faces 24a, 25a, the lower directional displacement of the slide 3 permits the upper part of the finger 20 to be displaced inward.  In this constitution, and while the head part 15 is grasped and the lower part of the body 2 is immersed in liquid 2, gas is captured in the bell 16, and the lower grasping part 20a is engaged in the groove 23 during its displacement.

Title: Air conditioner for multiroom system
Inventor: FUSHIMI MITSUZOU
IPC: F24F11/02
Filed: 1979-03-03
Abstract: PURPOSE: To simplify a compressor control circuit by a method wherein the frequency of a power source for a compressor motor is converted by both an air conditioner load signal and the operating rate signal of room units.  
     CONSTITUTION: An output device 4 for generating a signal corresponding to an air conditioner load comprises an outside-air temperature detector 5 and a setter 6 therefor, which represent the load and are constituted of a temperature-sensitive element 5a, e.g. thermistor, and a variable resistance 6a respectively. An output device 7 generates a signal corresponding to the operating rate of room units B. The two signals are fed to a frequency converter 3, for converting the frequency of a power source for a compressor motor 1 to a value corresponding to the signals. The converted frequency is set higher as the outside-air temperature and the operating rate are higher. Thus, the control circuit can be simplified without applying an excessive load to the compressor.
