Abstract: PURPOSE: To obtain a product to control or lower proliferation of bacteria and thrombotic formation by preparing a pellet blend of chlorhexidine and a hydrophilic polymer, heating the blend, extruding it from a die to make a medical product in which chlorhexidine being bulk dispersed in the polymer entirely. CONSTITUTION: A preparation method of an anti-infective medical product is to prepare a homogeneous molten material of a hydrophilic polymer and an anti-infective drug and extrude the molten material from a die to make a medical product in which the anti-infective drug is substantially uniformly dispersed in a bulk of the polymer. The extruded product may be dipped in a solution of chlorhexidine to provide additional chlorhexidine on a surface as a coating. The molten material is prepared by blending polymer pellets and chlorhexidine until an uniform coating of chlorhexidine is obtained on the polymer and heating it to make a homogeneous molten material. Polymer pellets and chlorhexidine powders are blended and molten simultaneously to prepare a homogeneous molten material which is then extruded from a blender to make tips.

Title: Pattern information inputting device
Inventor: MAEDA KENICHI
IPC: G06V10/20
Filed: 1980-01-28
Abstract: PURPOSE:To simplify an electrical signal processing system by vignetting the image pickup pattern from a photoelectric transducer in a pattern information input device of CCD scanner type. CONSTITUTION:The pattern image of characters and symbols stated on predetermined form is vignetted by an optical system 3 and is inputted to the photoelectric conversion surface of an image pickup device 1. The image information at the intermediate points of picture elements of the image pickup device 1 is obtained by an interpolation circuit 4, by which the signal of the vignetted pattern images is made continuous, after which this signal is led to a pattern recognition circuit 5. Since the picked-up image itself is vignetted in this way, the signal processing is considerably simplified, and even more, error factors are reduced, hence, the inputting of effective pattern information is made possible.

IPC: H02P27/06
Filed: 1982-01-21
Abstract: PURPOSE:To suppress the resonance phenomenon of an induction motor by increasing the slip frequency of the motor when the output frequency of a power source for driving the motor coincides with the intrinsic vibration of a mechanical system and operating the motor, thereby minimizing the sacrifice of the operating efficiency. CONSTITUTION:A DC power source 1 is inputted through an input filter circuit 2 to a VVVF inverter 5, the inverter 5 is controlled by a calculator 6 on the basis of the output of a sensor 7 such as a tachometer generator or the like and the slip frequency fs determined from the rotor current, thereby driving an induction motor 8 which is coupled to a mechanical system 9. When the output frequency of the inverter 5 coincides with the intrinsic vibration or its integer times of the mechanical system 9 at this time, the motor 8 is operated at the slip frequency larger than the slip frequency determined by the necessary torque. Accordingly, the sacrifice of the operating efficiency is minimized, thereby suppressing the resonance phenomenon which occurs between an electric system and the mechanical system.

Title: Coating pretreatment using atmosphere in heat treatment furnace
Inventor: KISHINO KUNIO
IPC: B05D7/14
Filed: 1979-01-29
Abstract: PURPOSE: To remarkably simplify and rationalize coating pretreatment through simultaneous surface cleaning and scale removal to prepare coating by quenching and heating welded and brazed iron based member in furnace of reducing atmosphere.  
     CONSTITUTION: Welded and generally brazed iron based members are placed in a heat treatment furnace and are heated for a given period of time at 700°C or more  in reducing atmosphere. The heating decomposes and burns organic material such as machine oil deposited on the surface and thus removes them from the surface completely. Also, oxide scale on the surface of member is removed by maintaining them at high temperature and in reducing atmosphere. Such surface-cleaned and heated member is dipped into water or rust-preventive liquid to effect rapid cooling and quenching. After dried, the member is coated. The process significantly simplifies conventionally needed processes such as degreasing, cleaning, drying, and eliminates the needs for degreasing agent, pickling agent, etc., thereby eliminating water pollution or waste water treatment and contributing to labor saving and rationalization.

     CONSTITUTION: The vapor-phase catalytic hydrogenation of an oxalic diester (a diester from oxalic acid and 1W8C alcohol) is conducted in the presence of a catalyst of silver or palladium supported on a carrier such as silica, alumina or active carbon at 120W300°C (at 200W240°C in case of a silver catalyst and 130W 170°C in case of a palladium catalyst preferably) to give the objective compound. The hydrogenation is effected under a pressure of 1W20 atmospheric pressure in a range of 0.01W20sec reaction time and the molar ratio of hydrogen to the oxalic diester is 2W600, preferably 20W200. Glycolic ester is formed in high selectivity and this process is practically preferred, because the catalyst contains no chromium component which may cause troubles.
