Title: Frictional material assembly
Inventor: NAKAGAWA MITSUHIKO
IPC: F16D69/00
Filed: 1985-03-01
Abstract: PURPOSE:To sufficiently restrain thermal cracks by securing fixedly to a back metal a pin reaching a frictional material and made of material having low hardness. CONSTITUTION:A pin has various cross sections such as circle, star and square ones and longitudinal sections of various shapes. While heat of a frictional material is transmitted through the pin 2 to somewhat raise the temperature of an adiabatic material, thermal strain is received by the pin due to integral molding so that the occurrence of thermal cracks is restrained. Since the pin 2 reaches the frictional material 1, the quality of the pin is limited such taht the pin has to have hardness which does not give critical damages to an opponent material when the pin makes frictional contact with the opponent material. As a result the occurrence of thermal cracks can be sufficiently restrained.

Title: Thermal recorder
Inventor: GOTO YASUHIKO
IPC: B41J2/44
Filed: 1992-02-27
Abstract: PURPOSE:To form an image of stable density without increasing the output of a laser output source by providing a plurality of laser beam generating means, and a scanning optical system for scanning a plurality of laser beams output therefrom on the different positions of a thermosensible recording material. CONSTITUTION:Laser beams L1 to L3 output from laser beam generators 12a to 12c are guided to a polygon mirror 20 via a cylindrical lens 16 and a reflecting mirror 18 with a prescribed angle difference of theta. At this time, the mirror 20 rotates at high speed and the beams L1 to L3 reflected on a reflecting surface are guided to a thermosensible recording material S via a ftheta lens 22 and the lens 16 and mainly scans the material S in the direction of A which is subsidiarily scanned and carried in the direction of B. Since the beams L1 to L3 are output with an angle difference of thetafrom the beam generators 12a to 12c, they scan different positions with respect to the main scanning direction of the material S. With time difference T1 between the beam L2 and the beam L1, the beam L2 reaches a pixel a1 to heat the material S whose temperature is being lowered with intensity I in order to maintain the same temperature. Thus, a blackening reaction time can be maintained and an image of stable density can be obtained.

Title: Seal member for heat-exchanger
Inventor: MIURA YOSHIMITSU
IPC: F28D19/04
Filed: 1995-02-07
Abstract: PURPOSE: To reduce the occurrence of thermal denaturation and to prevent gas leak between a seal member and a core by a method wherein means to lower bending rigidity are arranged at the two end parts in a longitudinal direction of the seal member of the cross arm of, a heat accumulation type heat-exchanger. CONSTITUTION: When a rotary heat accumulation type heat-exchanger is used in a gas turbine, the temperature of gas flowing through a low pressure high temperature gas passage 5 is increased to 1000 deg.C or more and a temperature difference of approximate 900-1000 deg.C is produced between a high pressure low temperature air passage 6 and the low pressure high temperature gas passage. In this case, since a cross arm part 21 of an inner seal 2 has a seal 21a made of a ceramic material coated with a surface material 21b, the coefficient of a thermal expansion is widely different therebetween, and thermal denaturation is produced. Thereby, slits 50 are formed in the thickness of the cross arm part 21 and the cross arm part is divided throughout a specified length 1, bending rigidity is reduced to 1/4 compared with a part having not slit 50.  This constitution maintains flatness of a slide surface 21d and an upper surface 21e opposite thereto and holds sealing ability between the cross arm 21 and a core slide part.
