  • Publication number: 20240103414
    Abstract: A fixing unit or device that can be used in an image forming apparatus includes a first heater element that is formed of a material that increases in electrical resistance with increases in temperature. A controller of the fixing unit is configured to vary a duty ratio of electric power applied to the first heater element during a start-up operation in which the temperature of the first heater element is raised to a target operating temperature. By varying the duty ratio during the start-up operation, changes in the resistance of the first heater element with the heating can be compensated. For example, the duty ratio can be increased during the course of the start-up to achieve the target operating temperature faster.

  • Publication number: 20220170688
    Abstract: Provided is a cold storage including: a sliding door; a lower frame for guiding a lower side of the sliding door, the lower frame having a recessed part; an upper frame for guiding an upper side of the sliding door; and a first sealing member having a first attachment part, which is a portion attached to the sliding door, and a first tip-end. A cross-sectional shape of the first sealing member is an arcuate shape. The first attachment part is located at the uppermost side of the first sealing member. The first tip-end is located at the lowermost side of the first sealing member. When a wheel of the sliding door drops into the recessed part, an outer peripheral surface of the first sealing member is brought into close contact with the upper frame or the lower frame.

  • Patent number: 6984435
    Abstract: A biaxially oriented, laminated polyester film having at least two layers, and in the film, an irregularity in film thickness determined within 4 mm width at an arbitrary position in a transverse direction of the film is about 0.1 ?m or less. This polyester film can satisfy both the electromagnetic conversion property and the running ability at a high level, particularly when the film is used as a base film for a large capacity tape for data storage.

  • Patent number: 4863008
    Abstract: A transfer apparatus for transferring objects to be processed, susceptible to damage, such as eggs and which includes a delivery conveyor for supplying rows of the objects successively. Adjacent to the delivery end of the delivery conveyor extend a secondary conveyor having a number of supporting stands which are fed in a direction perpendicular to the direction of movement of the delivery conveyor. A transfer device is interposed between the delivery end of the delivery conveyor and the secondary conveyor. The transfer device has a number of object receiving stands. A row of objects delivered from the delivery conveyor is placed on the receiving stands which are temporarily stopped. Thereafter, the receiving stands with the objects thereon are accelerated so as to move in parallel with the supporting stands until they reach the same speed as the supporting stands.
