Abstract: PURPOSE:To prevent an over-load from giving to the almost U-shaped central part of a spring material by defining an edge part, which is a contact surface, as an idle edge and for the other edge, providing a space between a back plane surface in the opposite side of the idle edge part in terminal metal fittings, which are spring elastic materials to be fixed by the supporting rib of a holding frame, and the holding frame. CONSTITUTION:The edge part to have the contact surface to be electrically connected is defined as the idle edge and for the other edge, a space part 20 is providing between a back plane surface 19 in the opposite side of the idle edge in terminal metal fittings 16, which are the spring elastic materials to be fixed to a supporting rib 18 of the holding frame. By the insertion of a pipe, a terminal 15 is inserted and elastically contacted to an idle edge part 24 of the terminal metal fittings 16. Then, the terminal 15 is deformed so that a U-shaped interval can be narrowed. At such a time, since the space part 20 is provided between the back plane surface 19 in the opposite side of the idle edge part in the terminal metal fittings 16, which are the spring elastic materials, and the holding frame 17, the deformation and moving of the back plane surface can be executed. Then, since the over-load is prevented from giving to the almost U-shaped central part, the resistance life of an electric connecting part can be extremely improved.

Title: Copying device
Inventor: ETO SHINJI
IPC: G03G21/00
Filed: 1989-06-07
Abstract: PURPOSE:To reduce a velocity at which an original is carried without decreasing copy productivity and to reduce noise by exposing and scanning an original by means of a scanning body while feeding the original, and making the relative velocity equal to the velocity of an image carrier. CONSTITUTION:While the original is fed, the scanning body 5 exposes and scans the original from the leading edge side in the original feeding direction; the relative velocity of the scanning body 5 and the original is made equal to the velocity at which the image carrier 1 moves. For example, when one copy is made from one original under the same magnification, the original is fed at a velocity of V/a, and the first scaner 5 moves at a velocity of (1-1/a)V from the original leading edge side, which is the opposite direction; here V is the circumferential velocity of a photosensitive drum 1. (where (a) is a continuous line equal to or more than one.) As a result, the relative velocity of them, which is a velocity obtained by adding the velocities of the original and the first scanner 5, is equal to the circumferential velocity V of the photosensitive drum 1. Thus, a speed at which an original is carried can be reduced without decreasing copy productivity, and noise of the copying device can be reduced.

Abstract: PROBLEM TO BE SOLVED: To keep incidence of specified solar beams to the interior of a room by a method wherein the indoor incident angle of solar beams is determined, and a blind is controlled based on an obtained indoor incident angle. SOLUTION: In the case when, at the place facing the south of a building, it is detected by a control group registration part 32 that an amount of sunshine detected by an outdoor illuminance detecting part 4 is below a low amount of sunshine, a sun altitude is calculated by a sun beam incident angle computing part 34 of a blind control part 36 set by a computation constant input part 31 and the sun altitude is obtained. Based on the sum altitude value, an incident angle to the place facing the south of a building is calculated to provide an apparent sun altitude. A blind height from a floor is obtained by a control group registration part 32. By a control timing deciding part 35 of the blind control part 36, a preceding target blind elevating state is compared with a current state and when the values are not the same as each other, a computing result is transmitted to drive part 2.  When the values are the same as each other, a computing result during a next control period is compared again. When the values are not the same as each other, the computing result is transmitted.

Abstract: PURPOSE:To prevent the blur of a light inlet window by forming a light inlet hole arranged in an inner tube into a trapezoid form having vertical sides to a direction of a reactive gas flow and providing a gas flow control wing directed to an inside of the inner tube on the side of the light inlet hole on an upstream side of the reactive gas flow while including that side. CONSTITUTION:On an upstream side of a light inlet hole formed in an inner tube, a gas flow control wing 5 is provided, which presses down a material gas flow(c')which has been made to Flow in the vicinity of a wall of the inner tube to a susceptor side and gives a downward compressive force, thereby cancelling an upward compressive force of a pressed-up material gas flow(g') near the susceptor. Accordingly, the material gas flow does not flow away through the light inlet gas hole, but it can be confined in the inner tube. A flow speed of a purge gas flow 9 is predetermined to be equal to or over a flow speed of the material gas on the susceptor. Consequently, a blur of the light inlet windw can be prevented and the light irradiation of a stable light density becomes possible.
