Title: Base metal plate for direct heating type oxide cathode
Inventor: MISUMI AKIRA
IPC: H01J1/15
Filed: 1978-03-31
Abstract: PURPOSE: To obtain sufficiently higher temperature strength and higher electric specific resistance, without almost causing the scaling of oxide layer, by giving suitable quantity of Re and Mo to the major component Ni as the base metal.  
     CONSTITUTION: In the direct heating type oxide cathode consisting of the oxide 3 for electron emission, base 1 heating it with power application, and current supply terminal 2, the base 1 takes Ni as the major constituent added with 2.0 to 5.5 atom% Re, 7 atom% or less Mo, and alloy including a trace of Zr as the reducing agent, for example, and it is made to the plate material of ribbon shape by repeating annealing and milling. Three element carbonate of Ba, Sr and Ca is coated on it to produce the oxide 3 with heating under vacuum. In this case, since the intermediate layer by Re is not almost produced between the base and oxide, no scaling of oxide layer is caused, and the strength at high temperature and electric specific resistivity can be increased with the addition of Mo which hardly contributes to the production of the intermediate layer.

Title: Corrosion preventive coating film
Inventor: TOKUNAGA KIKUO
IPC: F22B37/00
Filed: 1994-03-08
Abstract: PURPOSE:To effectively prevent corrosion caused by dew condensation of moisture by sticking a mixture of at least one of activated alumina and molecular sieve with MgO on a material to be protected from corrosion by using a silicate compd. for a binder. CONSTITUTION:A mixture of at least one of activated alumina and molecular sieve with 5-30wt.% MgO is applied on a material to be protected from corrosion by using a silicate compd. for a binder to form the objective corrosion preventive coating film. Since MgO is hard to disperse in the silicate binder and cakes at the time of directly mixing with the binder, it is well dispersed in the binder by mixing with activated alumina or molecular sieve as a hygroscopic agent for MgO and uniform dense adhesion to the surface of the steel material of a flue, etc., can be attained at the time of application. When the coating film is formed on the surface of the heat exchanger tube of a boiler, the wetting of the surface of the steel material can be prevented and a corrosion preventing effect is produced because the coating film absorbs moisture causing dew condensation at the time of low-load operation of the boiler or suspension.

Abstract: PURPOSE:To provide a molded product without scratches and cracks and provide high quality of transfered signs and high wear resistance by setting a film having an adhesive layer in one side and signs formed in the other side in the way the adhesive layer is set to face to a shallow impressed die. CONSTITUTION:A film 2 of polyester having colored layer 3 and signs 4 printed by silk screen method in one side and a silicone-based adhesive layer in the other side is set in a shallow impressed die 1 for forming contact points. The film 2 is fixed as a prescribed position by fitting a positioning pin 7 in a pin receiving hole 8 formed in the deep impressed die 9. That is, the film is so set as to make the side having the layer 5 face to the die face 1 and the die face 9 filled with resin is put on the die 1 and the resin is molded by heat pressing to transfer the signs to the resulting molded product. Consequently, since the molded product adheres to the die face 1 due to the adhesive force of the layer 5, the product can be taken out of the die easily. As a result, the molded product has no scratch and crack and the quality of the transfered signs and the wear resistance are improved.

Abstract: PURPOSE:To maintain recording paper feeding properties and make the mark of spurs inconspicuous on a printing surface by a method wherein a discharge means for discharging a recording medium after recording consists of a rotating body on the peripheral surface of which a plurality of projections are scattered so as to be circumferentially discontinuous. CONSTITUTION:After an ink cartridge 1 incorporating a recording head 1a is moved in the sub-scanning direction of a carriage 3 and recording for one line is completed, a feed roller 4 is rotated to feed a recording medium 2 in a main scanning direction for one line. At this time, a spur 6 is rotated as the recording medium 2 is fed to feed the recording medium 2 while depressing it on a guide member 8. In the spur 6, a cylindrical roller 6b integrally molded using a molding material, such as polyethylene, is mounted around the rotating shaft 6a, and on the peripheral surface thereof, needle-form projections 6c are scattered at random all over the surface so as to be circumferentially discontinuous. In this manner, since the recording medium 2 is held at a plurality of points, a pressing force is dispersed. Even when a recording medium 2 of a different size in a width direction is used, the medium can be smoothly discharged.

Title: Image sensor
Inventor: NAKAZAWA YOSHIO
IPC: H04N5/369
Filed: 1989-02-17
Abstract: PURPOSE:To simplify the constitution of a close contact type image sensor in spite of the long size and high resolution of the sensor by forming a scanning circuit having a longer transient time for the nonselection of a photoelectric conversion element as compared to a transient time for selecting the photoelectric conversion element. CONSTITUTION:The driving capacity of conductive switch elements P1 to P4 for transmitting information for the non-selection of photoelectric conversion elements D1 to D4 are set up to a value smaller than that of conductive switch elements N1 to N8 for transmitting information for the selection of the elements D1 to D4 and the transient time TOFF for the non-selection of the elements D1 to D4 is set up longer as compared to the transient time TON for selecting the elements D1 to D4. Since the driving capacity of the conductive switch elements for transmitting the information for selecting the elements D1 to D4 is higher and the transient time TON for selecting the elements D1 to D4 is shorter, a rapid signal reading output can be obtained. Since the driving capacity of the conductive switch elements for transmitting the information for the non- selection of the elements D1 to D4 can be reduced, the constitution of the scanning circuit can be miniaturized and simplified.

Filed: 1993-02-26
Abstract: PURPOSE:To allow easy and positive evaluation of noise occurring in the bearing for rotator by performing time history response calculation of bearing data to determine a bearing load, calculating dynamic and static powers of bearing load based on thus determined bearing load, and then calculating the ratio therebetween as a collision strength index between the rotator and the bearing. CONSTITUTION:A bearing load is determined by performing time history response calculation on bearing stiffness, internal pressure, inertial force, and combined force of belt while taking account of natural oscillation characteristics of crankshaft, stiffness and and metal clearance of oil film and cylinder block. Static bearing load and dynamic bearing load occurring upon collision of the bearing and crankshaft are then calculated based on the determined bearing load. The ratio is calculated as a collision strength index between the crankshaft and the bearing. Noise generating conditions can be evaluated based on thus calculated index. Noise generating conditions are evaluated based on the fact the index is within a lowest suppression region for suppressing noise between the crankshaft and a journal section or not.
