Title: Connection structure of outer combustion type hot air stove
Inventor: ONO CHIKAO
IPC: C21B9/10
Filed: 1993-06-23
Abstract: PURPOSE:To dispense with an iron shell reinforcement at the connect part in the base part of a connecting tube by specifying the ratio of the tube diameter of the connecting tube to the dome diameter of a regenerator and the ratio of the tube diameter of the connecting tube to the dome diameter of a combustion chamber, respectively. CONSTITUTION:The side wall of the dome 10 in the regenerator 1 and the side wall of the dome 11 in the combustion chamber 2 are directly connected with the connecting tube 4 without using a flexible joint to form an outer combustion type hot stove 12. In this hot stove 12, the ratio RD/TD of the tube diameter RD of the connecting tube 4 to the diameter TD of the regenerator 1 is specified to 0.24-0.60. Further, the ratio RD/ND of the tube diameter RD of the connecting tube 4 to the dome diameter ND of the combustion chamber 2 is specified to 0.44-0.60. By this method, the locally generated stresses at the base parts A, B of the connecting tube are suppressed and the iron shell reinforcements in the base parts A, B of the connecting tube are made unnecessary.

Title: Film for laser recording
Inventor: ITO MASANORI
IPC: G11B7/254
Filed: 1985-07-10
Abstract: PURPOSE:To markedly enhance image forming property and scratch resistance, by containing a heat ray absorbent having intensive absorbing capacity in the wavelength region of laser beam used in recording in both of a recording layer and a protective layer. CONSTITUTION:In a laser recording film wherein a recording medium layer 2 containing a non-self-oxidative binder resin and fine particles imparting high blackening density and absorbing heat is provided on a transparent substrate 1 and a protective layer 3 comprising a thermoplastic polymer is provided thereon, a heat ray absorbent having intensive absorbing capacity in the wavelength region of laser beam used in recording is contained in both of the recording medium layer and the protective layer. As mentioned above, if the non-self- oxidative binder is used, the apprehension of safety during storage or the corrosion of an oxidative substance generated at the time of the irradiation of laser beam undergoing in a self-oxidative binder is eliminated. The addition of the heat ray absorbent to both of the recording layer and the protective layer largely exerts effect on the transfer of the recording medium layer and has marked effect raising resolving power and can compensate the lowering in the recording sensitivity of layer due to the increase in a film thickness.

Abstract: PURPOSE: To set a copper lid at a place inward of the end surface of a rotary shaft by a method wherein when a heat pipe is assembled in a rotary shaft of an electric motor etc., the copper lid is pushed against the opening of the copper pipe in the rotaty shaft and a driving shaft of a friction welding machine is fitted to a groove of the copper lid.  
     CONSTITUTION: Groove 5a is made in an outer end surface of the copper lid 5, and fitted to a projection 6a of a driving shaft 6 connected to a friction welding machine and thereby the copper lid 5 is fixed to the leading end of the driving shaft 6. Copper pipe 2 is stored in the hollow rotary shaft 1, and if an expansion work for the copper pipe 2 is completed and the copper pipe 2 is fixed to the inside of the of rotary shaft 1, then the fixed shaft 1 is mounted in a chuck of the friction welding machine and the copper lid 5 is mounted in the driving shaft 6 of the friction welding machine, respectively. Since a rotational torque is transmitted to the groove 5a of the copper lid 5 through the projection 6a of the driving shaft 6, the copper lid 5 may not be necessary to be held by the chuck. When the copper lidf 5 is pushed against the opening of the copper pipe 2 while the chuck or the driving shaft 6 is rotated, both of them are friction contacted with each other and thereby the rotary shaft 1 having the heat pipe assembled therein may be made.

Abstract: PURPOSE:To provide a peeling of a solid phase layer of PCM generated when a heat is produced under a variation of shape of an object and output heat under a thermal medium of specified temperature by a method wherein a substance accompanied with a variation in phase (PCM) in a region of applied temperature and an object showing a variation in shape near a melting point of the substance are stored in a desired cell of a honeycomb structure. CONSTITUTION:PCM 2 is filled in a zig-zag form in respect to a plurality of cells of a honeycomb rib 1, a shape varying object 3 of which shape is varied with temperature is inserted into PCM 2. The cell filled with these substances is constituted by a thermal accumulation body with lids 4 at both ends, a shell 6 for guiding a thermal medium 3 for storing the thermal accumulation body and a thermal insulation material 7 present between the shell and the thermal accumulation body. With this arrangement, a contact are between the thermal medium 5 and PCM 2 contacting through the honeycomb rib 1 is increased, resulting in that a converted thermal calorie between the time of thermal accumulation and the time of thermal discharging can be increased. Since the shape of a shape varying object 3 is varied with a variation in temperature of PCM 2, a solid phase layer of PCM 2 formed in the rib wall surface is peeled off, a natural convection flow is generated and then a total thermal conductivity is increased.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To improve both of the initial discharge capacity and charge/discharge cycle characteristics by sticking a carbon material to fine holes formed in the surfaces of hydrogen storage alloy particles capable of reversibly storing/ releasing hydrogen.

Title: Device for feeding and locating stage
Inventor: KANAI MUNENORI
IPC: B23Q5/34
Filed: 1981-09-27
Abstract: PURPOSE:To improve the locating rigidity and stopping accuracy of a stage by adsorbing to a fixed member an adsorbing device mounted on the stage through a elastic body in the direction of feeding the stage when the stage is stopped for location. CONSTITUTION:A stage is constituted from a floating member 3 and a stage body thereon. After the stage is located and stopped, an adsorbing pad 21 is adsorbed to the bottom surface of a guide groove of a guide member 1 by vacuum force. Thus, the stage is coupled with the guide member 1 through an elastic body 17 as it is guided by static pressure fluid. At this time, since a leaf spring 20 has low rigidity in the direction of plate thickness, it has no effect on the accuracy in static pressure fluid guide and can locate and stop the stage only in the feeding direction. When the stage is driven by a drive as a adsorbing device is in adsorbing operation, the elastic body 17 is transformed in proportion to the drive force so that fine feed of the stage can be carried out.

In such a case, the blade to be used 8 is composed so that a free end is provided on the member 9. Then, it is preferable to bring the free end of the blade 8 in press-contact with the photoreceptor in the state where its direction may be opposite (counter) to the rotating direction of the photoreceptor.
