Title: Biaxially oriented laminated polyester film
Inventor: MINAMIZAWA HIDEHITO
IPC: B29L7/00
Filed: 1993-01-14
Abstract: PURPOSE:To highly dimensionally reconcile electromagnetic conversion characteristics and a tape edge damage when a polyester film is formed into a magnetic tape by adding particles to the outermost layer at least on a single side and setting the thickness of the outermost layer and the average particle size of the particles to specific relation and setting the Young's modulus of the film in the lateral direction thereof to a specific value. CONSTITUTION:Particles are added to the outermost layer at least on a single side and the relation between the thickness (t) of the outermost layer and the average particle size (d) of the particles is set to the range of 0.2<=t/d<=5 and the Young's modulus of a film in the lateral direction thereof is set to 600kg/mm<2> or more. Polyester films having these characteristics are sufficiently dried to be laminated using two or more extruders, two or more manifolds and a confluent block to form a non-stretched film which is, in turn, biaxially stretched. As preheating and stretching rolls, Teflon or silicone rolls are used in order to improve the surface smoothness of the film. Next, this film is heat- treated.

Title: Screw type gas compressor
Inventor: NOZAWA SHIGEKAZU
IPC: F04D3/02
Filed: 1978-01-23
Abstract: PURPOSE: To prevent the gas leakage and to improve the capacity of a compressor by providing a checking means to check the flow of the compressed gas circulating  in the gap between the discharging side of a rotor and the inner wall of a casing.  
     CONSTITUTION: When a driving shaft 12 is rotated, the low pressure gas sucked from a gas suction port 6 is compressed by compressing chambers successively formed between a male and a female rotor 2, and discharged to a discharge side passage 7. On the other hand, the high pressure gas leaked to the gap between the inner wall of a casing 1 and the discharge side of a rotor 2 also flows in and fills a groove 10. But, the refrigerant gas introduced from the gap and expanded in the enlarged part of the groove 10 is lowered in the pressure under the gas in the gap to generate the pressure difference between the upper and the down stream of the groove 10, and the gas leakage is intercepted by labylinth effect. Besides, the high pressure gas is supplied from a fluid passage 11 into the groove 10, and this construction serves to improve the preventing capacity of gas leakage greatly.

Title: Preparation of magnetic powder
Inventor: SAGUCHI HIROTO
IPC: G11B5/706
Filed: 1980-01-22
Abstract: PURPOSE: To prepare magnetic powder for magnetic recording use, having stable coercive force and high stability under heat and pressure, by carrying out the reaction of a Co salt with an alkali in a hot slurry of γ-Fe 2 O 3  dispersion, and if necessary, carrying out the addition of an aqueous solution of ferrous salt also under heating.  
     CONSTITUTION: γ-Fe 2 O 3  powder is dispersed homogeneously in water to obtain a slurry, mixed with a solution of a Co salt, e.g. solution of cobalt sulfate, heated at room temp. to 100°C, added with an alkaline aqueous solution, e.g. solution of caustic soda to precipitate cobalt hydroxide, and then added with an aqueous solution of FeSO 4  after cooling or under heating. The process promotes the penetration of Co ions into the γ-Fe 2 O 3  core, facilitates the precipitation of coarser cobalt hydroxide particles, increases the mutual interaction of the Co ions with ferrous ions, and improves the coecive force of the product. Furthermore, the stability against heat and pressure can be improved because of the closer contact of the cobalt hydroxide to the surface of the γ-Fe 2 O 3  particle.

IPC: F16K5/10
Filed: 1979-01-18
Abstract: PURPOSE: To discharge a fixed quantity of condensate from a steam system without installing a bypass, by creating an orifice in the main body of a valve.  
     CONSTITUTION: In the body of a valve 6, orifices 18, 19 are formed interconnecting passage 5 of the valve when the said valve is set in a "closed" position.

Title: Exhaust purifying device for lean combustion engine
Inventor: MASUKI ZENICHIROU
IPC: F01N3/10
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of the difference in level of torque when nitrogen oxide is reduced and discharged, and prevent worsening of fuel consumption, in a lean combustion engine having a nitrogen oxide storage reduction catalyst. SOLUTION: A fuel injection valve 11 is arranged at the peripheral part of the inner wall surface of a cylinder head 4 in the vicinity of the first and second intake valves 6a and 6b of an engine 1, and fuel from the fuel injection valve 11 is injected directly in a cylinder 1a. A throttle valve 23 opened and closed by a step motor 22 is disposed in an intake duct 20, and a nitrogen oxide storage reduction catalyst 56 is arranged in an exhaust duct 55. When an electronic control device(ECU) 30 performs rich spike control, an air-fuel ratio is increased by fundamentally reducing a throttle opening not merely by increasing a fuel injection amount. This constitution controls an air-fuel ratio to the rich side and executes reduction of a nitrogen oxide. Thus, torque is not rapidly increased and there is no need to effect a delay of an ignition timing.

Title: Radio channel switching method
Inventor: MIKI EISUKE
IPC: H04W84/08
Filed: 1994-01-24
Abstract: PURPOSE:To reduce the probability of interference after radio channel switching by simple control by selecting a radio channel having a higher quality to perform switching to this channel according as the frequency in radio channel switching of a call is increased at the time when the quality of the radio channel used by the call being in course of communication is lower than a required quality. CONSTITUTION:If interference occurs in a system terminal (e) a channel whose CIR value is 23dB or higher is selected at the time of first channel switching, and a channel whose CIR value is 26dB or higher is selected at the time of second channel switching. A channel whose CIR value is 35dB or higher is selected at the time of fifth and following channel switching. Since the quality of the assigned channel is increased by 3dB at each time of channel switching, the probability of the occurrence of interference is reduced. The loss probability is degraded because of the same channel assignment condition for the occurrence of a call as conventional.

Title: Method and device for "consensus synchronous type" data sampling
IPC: G06F17/30
Filed: 1993-01-18
Abstract: PURPOSE: To provide a method and device for picture processing which efficiently retrieve digital data stored in plural adjacent data cells on a photographic film. CONSTITUTION: An image sensor system 22 of an image sensor samples picture data in plural picture element positions in each data cell on a film 21 to generate gray scale picture data processed to a one-dimensional stream of binary picture elements. A data sampling system selects a binary picture element corresponding to the center of the data cell to process the binary picture elements. A transfer part detected in the stream of binary picture elements is used to periodically estimate a data cell pitch and a transfer part phase. Plural, for example, N presented distances from the current picture element to the next sampling point are determined by using transfer part phases of N latest transfer parts. A preferable sampling phase is determined through a histogram for the purpose of finding out consensus among N presented distances.  A digital output signal is generated from picture elements generated with a prescribed sampling phase.

Abstract: PURPOSE: To manufacture titled articles of high corrosion resistance of a resistance- welded zone by creating a vacuum or an inert gaseous atmosphere between the superposed metallic plates, welding these under said atmosphere, and performing the expansion and forming of the gap near the welded zone.  
     CONSTITUTION: Two sheets of metallic plates which are pierced with one or more opening holes 4 are superposed in an unformed state, and the circumference 5 is seam-welded on the outer side of the opening holes 4.
