Title: Weldable spheroidal graphite cast iron material and its welding joint product
Inventor: ASADA SHOSUKE
IPC: C22C37/04
Filed: 1995-03-08
Abstract: PURPOSE: To produce a spheroidal graphite cast iron material capable of welding free from the generation of cracks by reducing the content of carbon in the surface part in the welding part of a spheroidal graphite cast iron material. CONSTITUTION: The whole body of the base material of a spheroidal graphite cast iron material (such as FCD450) or only the welding part and its vicinity are buried in a decarburizing material (such as iron sand and mill scale). The temp. of the base material is increased to about 950 to 1100 deg.C in a heating furnace, and it is heated to the same temp. range for about 40 to 70hr. After that, it is cooled to about 200 to 300 deg.C for about 5 to 10hr and is discharged from a furnace. Thus, the content of carbon in the range from the surface of the base material to a depth of about 0.5 to 2mm can be reduced to about <=1.0wt.%, by which a weldable spheroidal graphite cast iron material can be obtd. This iron material is joined with an inexpensive steel by welding, so that an inexpensive structure having strength and toughness can be produced.

Title: Production of piezoelectric resonator
Inventor: YAMAMOTO TAKASHI
IPC: H03H9/02
Filed: 1979-06-22
Abstract: PURPOSE:To make an energy locking-in type piezoelectric resonator small-size and improve the quality of this resonator, by hardening the nonviscid insulating resin, which is provided in the vibration part of a piezoelectric substrate, in the resonance state. CONSTITUTION:Electrode patterns 2 are formed on both faces of piezoelectric substrate 1, and external taking-out lead wires 3 are connected to them. Next, unhardened nonviscid insulating resin 11 is provided in operating electrode 10 of electrode pattern 2 and a range wider than the region where main vibration is attenuated sufficiently. The input of the resonance frequency is applied from the external, and the vibration part of substrate 1 is caused to resonate at a level  stronger than that of the use state, and resin 11 is hardened in this resonance state.  Next, after hardening of resin 11, substrate 1 is molded with insulating resin 12 so  that the whole of substrate 1 may be covered with resin 12. Since resin 11 is hardened under the resonance state in this manner, resin 11 is not brought into  contact with the vibration part. Thus, the resonator can be small-size, and irregularity of the quality can be reduced.

Title: Manufacture of hose joint
Inventor: NISHIKAWA MASAYUKI
IPC: B21D53/00
Filed: 1987-03-31
Abstract: PURPOSE:To reduce a manufacturing cost and to improve the yield by forming a tubular body with the bottom opening one end with the plastic deformation of a metal blank stock and after flattening the bottom part side face, piercing a through hole and fixing the nipple subjected to drawing to the opening end as well. CONSTITUTION:The tubular body 24 having an opening end part 22 and bottomed end part 23 is formed in advance with the plastic work of a plate like metal blank stock to manufacture a nipple 7 by drawing a separate plate like metal blank stock. After forming the flattened part having both side faces by leaving a space in the center by pressing the side face of the bottom 23 of the tubular body 24, a core 26a is blanked by inserting it into the through hole 8. The nipple 7 separately formed is fixed by inserting to the inner side of the sleeve 2 of the tubular body. Since the tubular body 24 and nipple 7 are manufactured with plastic working only without any machining and a joint is formed by fixing both, the prepg. cost is reduced and the yield is improved.

Title: Automatic distributing method of section having difference of folding in feeder for sewing bookbinding machine
Inventor: ISHIDA TADAYOSHI
IPC: B42B9/00
Filed: 1980-06-13
Abstract: PURPOSE: To mount the section simply on a saddle so as to open the folding of the section by a method wherein a longer folded piece among the sections having the difference of foldings is forced to be opened outwardly by a rammer at the inside of the lower projecting section thereof to drop it onto the saddle.  
     CONSTITUTION: When the section 6 having the difference of folding is supplied upwardly under keeping the fold 7 at the uppermost position and directing it into the fore-and-aft direction, the section 6 is sent downwardly in a hanging condition from the space between sending rollers 2, 3 after passing through the space between feeding rollers 1, 1. At this moment, the rammer 8 is reciprocated from the fore side of a machine toward rearward side obliquely to push and open the lower end of a longer folded piece 4 in the section 6 outwardly by the rear end of the rammer 8. When the section 6 is dropped onto the saddle 9 located below the feed roller 2 closed to the other folded piece 4 as it is by a subsequent downward feeding of the section 6 effected by the roller 2, the section 6 is mounted on the saddle 9 in a condition that the folding is opened as it is desired.

Title: Dynamic pressure air bearing type optical deflector
Inventor: IWAMA AKIHIKO
IPC: F16C17/10
Filed: 1985-04-13
Abstract: PURPOSE:To simplify the structure of an optical deflector by composing a rotating body of a hollow cylindrical rotor made of a semihard magnet material, a thrust collar made of light metal such as aluminum, and a polygon mirror made of small-diameter, thin aluminum. CONSTITUTION:A fixed shaft 4 is made of metal such as stainless steel and aherringbone groove for the function of a radial dynamic pressure bearing and a spiral groove for the function of a thrust bearing are formed in the peripheral surface of the fixed shaft. A stator 6 consists of plural iron cores and coils, which are arrayed at the outer periphery of the rotor 1 on a polyphase basis; and a clearance of about 3-6mum is given between the hollow cylindrical rotor 1 and fixed shaft 4. When the rotating body begins to rotate and its rotating speed increases above a specific value, the rotating body rotates together with the fixed polygon mirror 3 without contacting, so the size and weight are small and the structure is simplified.

Title: Polymer electrolyte fuel cell
Inventor: HADO KAZUHITO
IPC: H01M4/90
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To efficiently remove moisture in the pores of an electrode and enhance the performance especially in high current density by using a hydrogen storage alloy in at least part of an anode constituting material. SOLUTION: A boundary 2 where an electrolyte 3 comes in contact with fuel gas is formed in an electrode constituted with electrode material powder 1. The anode of a polymer electrolyte fuel cell is a gas diffusion electrode, and electrode reaction proceeds on the three phase interface where hydrogen of fuel gas, the electrode, and the electrolyte exist together. The cell performance is enhanced with increase in the effective surface area on the three phase interface to the apparent electrode area. By using hydrogen storage alloy in at least one part of the anode constituting material, hydrogen is absorbed in the electrode solid, and at the same time, since the hydrogen is capable of moving in the electrode solid, the area of the three phase interface where the electrode reaction proceeds is increased as shown in Fig. 10, and the cell performance is enhanced.
