Title: Projector
Inventor: TOKUHARA MICHIHIRO
IPC: G03G15/041
Filed: 1982-12-27
Abstract: PURPOSE:To match accurately end surfaces by using a vari-focal lens for an image forming lens system and moving this lens on specific condition. CONSTITUTION:A projection lens varies in a principal point interval with its focal length, but the distance between the center and front principal point of the lens is equal to the distance between the center and a rear principal point invariably. The center position of the projection lens at image-formation magnification beta in relation to the center position when the image formation magnification is unmagnification, shift by K in an optical-axis direction of the projection lens and by DELTA at right angles to the optical axis of the projection lens. Those K and DELTA are calculated from equations I and II, where L is the sum of the distance between the front principal point and an original surface and the distance between the rear principal point and a specific projection surface in unmagnification image formation, DELTAH is the variation in the principal point interval of a projection lens system in image formation of magnification beta in relation to the unmagnification image formation, and Y is the distance between the optical axis of the projection lens and an original surface end part in life- size image formation.

Filed: 1989-09-04
Abstract: PURPOSE:To make assemblage easy and to make quality stable, by a method wherein for a rotary drum, a bearing consisting of both a sliding member and felt member is provided, and a bearing member with the sliding member bonded is provided on a recess which is formed by compressing a part of the felt member. CONSTITUTION:A sliding member 19 has a function of preventing the abrasion owing to sliding of a rotary drum, and a felt member 20 has a function that it is made rotatable between the rotary drum and a drum supporting plate 24 and is also made airtight between them. That is to say, the function is to prevent the leakage of wet air in the rotary drum and to surely send the wet air to a heat-exchanging fan. Furthermore, since the sliding member 19 is joined in a recess 21 on the felt member 20, the non-contact part between the felt member 20 and the rotary drum can be made minimum as compared with simple joining and the airtightness between the felt member 20 and the rotary drum is improvd. On the other hand, by the construction that the sliding member 19 is joined on the felt member 20, the vibration owing to the revolution of the rotary drum will not be transmitted because of the flexibility of the felt member 20, and hence it is effective in the reduction of the vibration.
