Title: Feeder for cut sheet for photographing film
Inventor: MAEDA TOSHIKAZU
IPC: B65H1/26
Filed: 1988-06-10
Abstract: PURPOSE:To surely pick up a cut sheet one by one by separating a sucker compulsorily from a subordinate cut sheet by moving the sucker above and backward with respect to the feeding direction of the cut sheet after the upper- most cut sheet of an unphotographed film inside a cassette case is adsorbed by negative pressure. CONSTITUTION:After the negative pressure operating sucker 28 of a sucker device 29 is temporarily descended in condition where it is operated by negative pressure from the starting point above the film gateway of the unphotographed film housing cassette case and the upper most cut sheet of an unphotographed film is adhered by negative pressure to the sucker 28, the sucker 28 is moved above and backward with respect to the feeding direction of the cut sheet. While only the upper-most cut sheet is rolled backward, the shift power in the surface direction is applied between the upper-most and subordinate the sheets to forcibly separate them. Thus, the upper-most cut sheet can be surely picked up one by one and the entrainment, etc., of adhered sheet can be prevented.

Title: Designing method for network
Inventor: AIHARA TOSHIYUKI
IPC: G06F17/50
Filed: 1995-06-12
Abstract: PURPOSE: To provide a method for designing a network by which the design based on the comprehensive evaluation of various kinds of communication quality and cost of the network is made possible. CONSTITUTION: When the candidates of a new network constitution are determined (s1, 2), the communication quality of the network such as maximum delay and maximum error rates and the cost of the network are determined (s3, 5, 7). A comprehensive evaluation value is determined by using the comprehensive evaluation expression of the network in which a preliminarily determined weighting is reflected on the various kinds of communication quality of the network and cost (s10). If the determined evaluation value is more excellent than the present network constitution, the new network constitution is used in place of the present network constitution.

Filed: 1991-06-17
Abstract: PURPOSE:To provide an expansion type color selecting electrode body structure such that a predetermined tension is applied across an aperture grill by preventing a plastic deformation of supporting rods on which the aperture grill being expansively fitted under tension. CONSTITUTION:Supporting rods are designed to be trapezoidal-shaped or similar- shaped in cross section, the inside of which is approximately equal to the incident angle of an electron beam, the plastic deformation of the supporting rods 21 is prevented in such a way that the section modulus of the supporting rods 21, relative to the direction of a bending moment acting on the supporting rods 21 when an aperture grill 1 being expansively fitted under tension, is designed to be larger. If a frame 2 is deformed by the predetermined quantity, the supporting rods 21 are not plastically deformed, so that the aperture grill 1 can be stretched under a predetermined tension.

Title: Method for improving secondary combustion rate and heating efficiency of melting furnace, or the like
Inventor: KIKUCHI YOSHITERU
IPC: C22B1/20
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To increase the secondary combustion rate and heating efficiency of a melting furnace, etc., without shortening the service lives of refractories, etc., and suppressing the flying out of slag, etc., by using a gas containing an oxygen gas more than a specific amount as a combustion supporting gas for secondary combustion. SOLUTION: The method for improving secondary combustion rate and heating efficiency of melting furnace, etc., uses a gas containing >=60% oxygen gas as a combustion supporting gas for secondary combustion. In order to heat the oxygen gas for secondary combustion to a high temperature, oxygen gas preheaters 5 are installed to the oxygen gas introducing sections of lances 2. Because of the preheaters 5, the oxygen gas can be heated to a temperature of about 1,100 deg.C and the temperature of the oxygen gas at the discharge ports of the lances 2 can be maintained at >=950 deg.C. In addition, the flow speeds of the oxygen gas discharged from nozzles are set at 100, 250, and 500 m/sec.  Therefore, when the melting of a raw material is accelerated or the temperature in a melting furnace, such as the converter, electric furnace, etc., is raised at the time of melting the raw material in the furnace, the raw material can be melted by reducing the used amount of fuel or the combustion supporting gas without worsening the operability of the furnace nor damaging refractories by improving the heating efficiency of secondary compustion.

Title: Exhaust gas purifier for internal combustion engine
Inventor: KATOU TAKASHI
IPC: F02M7/24
Filed: 1982-08-23
Abstract: PURPOSE:To secure a high purification efficiency in the transient operation of an engine, by changing to a larger second value the amplitude of a drive signal for a solenoid valve for opening and closing an air bleed passage, in the transient operation. CONSTITUTION:When the negative pressure in an intake manifold 1 has sharply changed, namely, transient operation is performed, the movable contact 68 of a transient operation detector 60 comes into touch with one of fixed contacts 69, 70 to apply a voltage to turn off a first analogue switch 53 and turn on a second analogue switch 54. As a result, a saw-toothed voltage of larger amplitude is applied to a voltage-current converter 55 to increase the change width of the cross-sectional area of the opening of a valve port 37 to enlarge the fluctuation width of the air-fuel ratio of a mixture. Although the reference air fuel ratio of the mixture slightly differs from a theoretical air-fuel ratio due to the instantaneous evaporation of fuel clinging to the inside surface of the intake manifold 1 or due to the like in the transient operation, a high purification efficiency is attained by the enlargement of the fluctuation width of the air- fuel ratio.

Title: Method for adjusting glass bead sample for x-ray fluorescence analysis
Inventor: IWATA TOMIO
IPC: G01N1/28
Filed: 1993-06-16
Abstract: PURPOSE:To form a smooth and flat sample with which the analyzing accuracy can be improved by putting a sample on a sample dish together with a flux and pre-melting the sample with a heating device, and then, again heating and melting the glass bead sample on the sample dish after the pre-melted sample is cooled and pulverized. CONSTITUTION:A sample is put on a sample dish made of platinum or an alloy of platinum and another precious metal and heated and melted with a heating device. Then, after cooling and pulverizing the glass bead sample, the sample is again put on the sample dish and heated and melted with the heating device. When a sample containing a reducing component or a sample containing a hydrous mineral or carbonate is heated and melted, the reducing component reacts to the precious metal component in the dish and forms an alloy or bubbles are generated during the melting, the reducing component is already oxidized when the sample is again melted after pulverization and no bubble is generated. Therefore, even when the sample contains a reducing component, hydrous mineral, or carbonate, the reducing component, hydrous mineral, nor carbonate does not form any alloy nor generate any bubble, because it does not react to the platinum or precious metal component.

Title: Fan device installed onto heat exchanger
Inventor: AKAIKE SHIGERU
IPC: F04D29/54
Filed: 1989-06-09
Abstract: PURPOSE:To reduce the noise due to the disturbance of air stream by setting the blade top edge of a cooling fan in inclination for the axis direction and setting a fan shroud oppositely to the blade top edge through a nearly uniform tip clearance. CONSTITUTION:As for the radiator 2 of an engine 1, the blade top edge of a cooling fan 8 is not parallel to a shaft 7 and on one supposed conical surface and has a tilt angle (alpha) for the direction of the shaft 7. Further, also a fan shroud 4 is set oppositely to the blade top edge through a nearly uniform tip clearance (t) on the outer peripheral part 9 of the fan 8. Therefore, the angle theta' which is formed between the outer peripheral part 9 of the fan 8 and the connection part 5 of the fan shroud 4 through the contraction of the outer peripheries of the radiator 2 and the fan 8 reduces by the tilt angle (alpha). Since the angle formed by the above-described both is small, because of the inclination of the fan shroud 4 in two states, the generation of noise due to the disturbance of air stream can be reduced.
