Title: Cage for cylindrical roller bearing
Inventor: ITO HIDEJI
IPC: F16C33/46
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide an integral type cylindrical roller bearing cage that can ensure uniform lubrication of a roller without damaging the roller at the time of pressing in. SOLUTION: Guide faces of a cylindrical roller 4 are formed of circular arc faces 6. Each circular arc face 6 is connected to the inner peripheral surface 8 of a cage through a plane part 7. Two plane parts 7 opposed in each pocket 3 are formed to be parallel to each other, and a space between them is formed to be slightly smaller than the diameter of the cylindrical roller 4. The cylindrical roller 4 pressed into the pocket 3 of the cage is therefore pressed uniformly to each plane part 7, and the plane part 7 and the outer peripheral surface of the cylindrical roller enclosed in the cage form a uniform wedge shape in the axial direction of the cylindrical roller 4.

Title: Forming method for truncated-conical contact
Inventor: IMAI MASAMITSU
IPC: B21K1/62
Filed: 1988-01-29
Abstract: PURPOSE:To enhance nondefective rate of a truncated-conical contact by inserting a contact piece into a bell-like opening portion formed on a punch so as to form it by the effect of the abutment of the punch against a fixed die, and ejecting the formed contact by the press of a spring incorporated in the punch. CONSTITUTION:A contact piece 8 stops in front of the central portion of a flat fixed die 9 by means of a transfer device, and a knock pin 11 and the die 9 hold the contact piece 8, and further a punch 10 advances so as to abut against the die 9. The contact piece 8 expands outwardly at a bell-like opening portion 12 formed on the fore end of the punch 10 so a to become a truncated- conical contact 13. And the press of a spring 14 incorporated in the punch 10 pushes the knock pin 11 so as to eject the truncated-conical contact 13 formed at the bell-like opening portion 12. Therefore, the truncated-conical contact 13 is completely removed so as not to generated any twice-punching formed, thereby enhancing yield.

Filed: 1994-02-16
Abstract: PURPOSE:To enhance the holding force of a catalyst compsn. and to also enhance the peel strength of a metal lath base material even to which no flame spraying is applied by forming notch like unevenness specified in depth and size to the surface of the metal lath base material of a catalyst. CONSTITUTION:Notch like recessed and protruding parts 2 having depth which is larger than the diamdter of a catalyst compsn. and a reinforcing fiber to be mixed and desirably 10mum or more and equal to or less than 1/2 or less the thickness of a thin metal plate and a pitch smaller than the dimension of lath meshes 3 are mechanically formed on the thin metal plate to roughen the surface thereof. Thereafter, metal lath processing is applied to this metal plate to obtain a base material. The catalyst compsn. enters the notch like recessed and protruding parts 2 and, even when the number of the recessed and protruding parts 2 is less, the drying shrinkage of a catalyst paste is suppressed in the same way as flame spraying. Since the crossing part of each of the notch like recessed and protruding parts 2 and a lath notch cross section is sharpened in its end part, the crossing part functions as the mechanical resistance part to the detachment of the catalyst compsn. to impart holding force to the catalyst compsn.

Abstract: PROBLEM TO BE SOLVED: To correct vertical variation in the optical axis of light made to exit from a light source device which is generated due to the thermal deformation of a housing of an optical scanner. SOLUTION: The housing 12 of the optical scanner 10 is fixed on a body frame 18 of an image forming device. The light source device 20 including a light source 88 and a collimeter lens 58 is supported on the outer peripheral wall 22 of the housing 12 through supporting legs 48, 74. These legs 48, 74 support the upper and lower parts of the device 20 at a prescribed interval and the extension length of the leg 74 due to a change in temperature is longer than that of the leg 48. When the device 20 is inclined in the vertical direction of the wall 22, the angular variation of the optical axis of a laser beam made to exit from the device 20 is offset. Since the laser beam is not kicked before arrival at a photosensitive body, fine image quality can be obtained.
