  • Publication number: 20250068103
    Abstract: An image forming apparatus includes a first rotatable member, a second rotatable member, an air nozzle, and a pipe. The pipe includes a portion provided in a range overlapping with the first rotatable member and making one reciprocation or more in a case that when a direction crossing a feeding direction of a recording material fed in a nip is a widthwise direction of the first rotatable member, the pipe is viewed in a direction perpendicular to the widthwise direction.

  • Patent number: 6670627
    Abstract: A surface examining apparatus irradiates an examinatorial light from a projector on a examined body that runs in a Z-direction. The projector is arranged at a distance from the surface of the examined body in a Y-direction orthogonal to the surface thereof and arranged inwardly of outer ends of the examined body in the width direction thereof in the X-direction orthogonal to the Z-direction and the Y-direction, and which detects the light that has passed through the examined body thereby to examine surface defects of the examined body. A light shielding unit is provided, which includes a light shielding member arranged between the projector and the examined body and shields the examinatorial light that is going to travel outwards from the outer end in the width direction of the examined body, and a moving unit that moves the light shielding member in the X-direction and in the Y-direction.

  • Publication number: 20020026863
    Abstract: A perforator for making perforations in a continuous film which is thereafter cut into individual filmstrips having variable lengths. A die set unit of the perforator has a plurality of punches and corresponding dies which are respectively arranged along the continuous film. The die set unit performs die-punching N times (N=1, 2, 3 . . . ) in every first section having a variable length Lx, and the measuring feeder transports the continuous film by a first length after each of (N−1) times die-punching and by a second length after the last die-punching for every first section. The first length is given as Lx/N, and the second length corresponds to the first length plus the length L2 of a second section disposed alternately with the first section along the continuous film. In alternative, the die set unit is constituted of first to nth die sets aligned in order from downstream to in the film transporting direction. The ith die set of the die sets has a number Gi (i=1, 2 , . . .

  • Patent number: 5694294
    Abstract: In a portable personal computer in which high-exothermic devices are mounted within a flat case equipped with an input unit, the and in which a surface temperature of the exothermic devices and the input unit is cooled down to or below a predetermined temperature. A first space is created between the back of a keyboard operating section and an electronic circuit board 3, the electronic circuit board 3 is installed so that the face thereof on which the high-exothermic devices are mounted faces away from the back of the keyboard, a second space is created between the electronic circuit board 3 and an electronic circuit board 2, and a fan 4 is installed inside the case so that cooling air flows from the first space to the second space. A flow path for circulating outside air into the case via an air intake hole 8 is constructed on the wall of the input device operating section.

  • Patent number: 5673602
    Abstract: A perforator has a rotary drum. A plurality of die sets are arranged at regular intervals around a peripheral surface of the drum and circulates along with the peripheral surface. Each of the die sets has a pair of die and punch. The die is secured to a die holder which is mounted to the peripheral surface, and the punch is secured to a punch holder which is linearly movable in a direction perpendicular to the peripheral surface between a punch position where the punch is fitted in the die and a retracted position where the punch is retracted away from the die. The sheet material is brought into contact with the peripheral surface within a predetermined range, and conveyed on the peripheral surface in the same direction at the same speed as the die sets. An annular punch drive cam disposed surrounding the peripheral surface drives the punch holder to move between the punch position and the retracted position.
