Title: Method and device for partially lining inner surface of pipe
Inventor: ISOGAI HIROSHI
IPC: B05C7/08
Filed: 1987-03-20
Abstract: PURPOSE:To form a partial coated film on the inner surface of a pipeline by inserting a tube contg. a lining material and a pig for forming a coated film on the inner surface of the pipeline into the pipeline, separating the pig from the tube, and pushing the lining material ahead by the pig. CONSTITUTION:The tube 4 contg. a sufficient lining material 3 for lining the inner surface of a pipeline 1 to be partially lined and the pig 7 for forming a coated film on the inner surface of the pipeline 1 are pushed into the pipeline 1 by the rod 2 connected to the pig 7 and sent to the relevant place. A tow rope 9 fixed to the tube 4 is then pulled to separate the pig 7 and the tube 4, and the rod 2 is pulled back to discharge the material 3 in the tube 4 to the outside of the tube 4. The material 3 is pushed ahead by the pig 7 from the rear to partially form a coated film on the inner surface of the pipeline 1. Namely, only the desired place can be lined, and the consumption of the material is reduced.

Title: Cylinder device
Inventor: ISOBE MASABUMI
IPC: F15B11/032
Filed: 1981-04-30
Abstract: PURPOSE:To produce the high pressure when the external force is high, by providing a mechanism for pressing a rod by means of the fluid supply and a valve mechanism which functions at the pressure higher than predetermined level thereby functioning a speed increase piston through the functioning of said valve. CONSTITUTION:When supplying the pressurized air to a port 21, an idle piston 14 will move to the direction G and the oil in the chamber C will flow into the chamber E thus to move a rod 2. A valve mechanism 6 will close as the external force will increase thus to block between the chambers E and C and to close the chamber E tightly, while when the pressure of the compressed air supply will increase further the valve mechanism 18 will function to flow the compressed air into the chamber B thus to pressurize a booster piston 13 and to move a ram 10 in the direction G. Since the chamber E is closed tightly and the cross-section of the ram 10 is smaller than that of the booster piston 13, the chamber E is brought into the high pressure thus to pressurize the rod 2.

IPC: H05H1/18
Filed: 1985-03-31
Abstract: PURPOSE:To protect a coaxial tube from the action of an electromagnetic force by providing an electromagnetic shield member having a large conductivity so as to cover the coaxial tube externally. CONSTITUTION:The electromagnetic shield member 14 is formed by a conductor material having a large conductivity such as copper, fitted concentrically to the outer side of the coaxial tube 11 via plural turning-prevention reinforced ribs 15 and fixed to a tube casing 10 via a turning-prevention reinforced rib 16. Even when an electromagnetic force due to an eddy current acts on the electromagnetic shield member 14 attended with the change in the magnetic field due to plasma collapse, the electromagnetic shield member 14 is reinforced sufficiently by the turning-prevention reinforced ribs 15, 16 and fixed and supported stably. Thus, the changing magnetic field due to plasma collapse is not invaded into the coaxial tube 11 and it is not required to provide an insulation spacer for preventing turning between both tubes 11a and 11b.

Title: Image forming method and thermal transfer ink ribbon used for the method
Inventor: FUJITA IKUO
IPC: B41M5/392
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To protect a head against wear by preventing the thermal head from touching a thermal ink ribbon by transferring the thermal ink ribbon containing a magnetic body by a laser. SOLUTION: As a thermal ink ribbon containing a magnetic body is used, the magnetic body itself has an enough sucking force from a visible light section to an infrared section. Therefore, the range of choice of a laser as a transmission frequency is broad. The driver 2 of a semiconductor laser is turned on and off in accordance with information from a computer 1 that controls the generation of magnetic image data and the driver of a laser head 3, which transfers a magnetic body-containing layer 4 and forms a magnetic body image information. When the image information is data on a bar code, for example, as a method of forming an image pattern on a card-form recording medium, a laser beam is scanned by using an optical system such as a polygon mirror, or a laser head is moved for scanning over the medium.

Title: Press die
Inventor: HAMADA KAZUO

Abstract: PURPOSE:To obtain a press die for reducing a noise generated between a punch and a die of a punching die, especially, an impact sound generated between a stripper and a die element in the course of press work, by constituting so that mass of the stripper is made small and its vibration factor is reduced. CONSTITUTION:A plate material 13 is placed on a stripper block 38 of a die in order to work a product such as a washer, etc. Subsequently, when a punch 12 descends, a die plate runs against a block 38 through the plate material 13, it is made to descend against a coil spring 50, and during that time, the product is punched. On the other hand, when the punch 12 ascends, the block 38 is reset to its upper original position by an action of the spring 50, and during that time, the plate material 13 is separated from an outside diameter punching punch of the die 14. As a result, the block 38 brings on an effect for remarkably reducing vibration and an impact sound which are generated due to a fact that the die plate runs against said block, comparing with the case by a conventional stripper.

Title: Record player of cartridge self-running type
Inventor: MORI YOSHIHISA
IPC: G11B3/40
Filed: 1978-06-09
Abstract: PURPOSE: To turn off power supply to a motor and achieve automatic stopping of the travelling body by letting the turning member provided to the travelling body displace largely in the final position of a record.  
     CONSTITUTION: As the stylus 26 of a cartridge 20 traces the modulated grooves 34 of a record disc, the catridge 20 gradually and subsequently turns toward the inner side of the record disc together with an arm 25 with the adjusting axis 23 as a fulcrum, along with which a guide 19 also turns to the inner side with respect to the traveling direction. In follow up to this turning, the travelling body 2 subsequently moves gradually to the inner side while travelling on the record disc. When the stylus 26 is guided in the endless groove after the modulated grooves of the disc in this way, the displacement angle of the arm 25 about the adjusting axis 23 increases to open a switch 10, thereby cutting the power supply to the motor. By detecting that the stylus has been guided into the endless groove of the record disc in this way, the travelling body may be stopped automatically.

Title: Metal-ceramics composite material and its production
Inventor: SHIMOJIMA HIROMASA
IPC: C22C47/08
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To obtain a metal-ceramics composite material in which the infiltrating time of metal is short by composing the outside of a preform of ceramics powder such as SiC, Al2 O3 , AlN having a powder filling rate higher than that of the inside and composing the inside of the preform of ceramics powder of the kind same as that of the outside having a powder filling rate lower than that of the outside. SOLUTION: Since, in the inside part of the preform, the powder filling rate is made lower than that of the outside, metal infiltrates into the inside part at first, and, with it as the starting point, the infiltrated metal radiately infiltrates into the preform on the outside as well, so that the infiltrating time can remarkably be reduced compared to the case in which the metal infiltrates in one direction. Moreover, as to the outside of the preform, since the whole face is opened to a nitrogen atmosphere, even when the metal radiately infiltrates, the feeding directions of gaseous nitrogen are made reverse in all, and there is no fear of occuring noninfiltrated parts in the outside part having a high powder filling rate. The powder filling rate is regulated to 50 to 80vol% as to the outside part and to <50vol% as to the inside part.
