IPC: B32B43/00
Filed: 1988-11-22
Abstract: PURPOSE:To prevent the generation of defective winding-appearance such as a wrinkle, and to enable laminating bonding having excellent appearance by winding a laminated adhesive film after the passage of a heating pressure roll while the position of the film is varied between the heating pressure roll and a cooling roll and the film is taken off successively through the cooling roll by an auxiliary roll mounted in a contact pressure-possible manner with the cooling roll. CONSTITUTION:A clearance between heating pressure rolls, a heating roll A and a nipple roll C, is supplied with two raw material films to be mutually laminated and bonded. Since proper adhesives are applied onto the surface to be superposed of at least one film in the raw material films, the films after passage through the heating roll A and the nipple roll C are heated and pressure, and changed into a laminated adhesive film. The laminated adhesive film is taken off through an auxiliary roll E and a cooling roll B, but a clearance between the auxiliary roll E and the cooling roll B is kept at a proper value by adjusting horizontal and vertical moving mechanisms in the auxiliary roll E, and the laminated adhesive film is wound so as to be brought into contact with the cooling roll B as uniform as possible.

Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a compact camera constituted so that any parallax is not caused and the state of focus is easily confirmed through a finder by forming a primary image equivalent to an image formed by luminous flux for photographing on a diffusion plate. SOLUTION: This camera is constituted so that the diffusion plate P1 is arranged at the position of a primary image surface I1 and provided with a photometry element SE executing a photometry action by using light from the plate P1. By a half mirror HM1 arranged between a front group L1 and a rear group L2, the luminous flux made incident on a photographing optical system is split to the luminous flux for photographing being the transmitted luminous flux and the luminous flux for a finder being the reflected luminous flux on the way to the photographing optical system. Thus, an object image is formed on a film surface N1 by the photographing optical system and the primary image is formed at the position of the primary image surface I1 by a finder optical system.  Therefore, since the primary image equivalent to the image formed by the luminous flux for photographing is formed on the plate P1, the state of focus of the photographing optical system can be confirmed through the finder.

Title: Throttle controller for internal combustion engine
Inventor: KAMADO KOICHI
IPC: F02D9/02
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To improve following-up stability of the opening of a throttle valve in an electronic throttle system. SOLUTION: In an electronic throttle system, a real throttle opening TA (opening of a throttle valve 5) is easy to overshoot by receiving the influence of inertia when friction becomes small with a small number of part item and a simple mechanism. To suppress this tendency, and make the real throttle opening TA coincide with a command value as a targeted opening, a controlled variable to be converted into control current for driving a torque motor 19 is corrected according to velocity deviation between the transition velocity of the command value and the transition velocity of the real throttle opening TA. It is thus possible to prevent an overshoot or the like from occurring by correcting the controlled variable appropriately according to the velocity deviation, and improve following-up stability of the real throttle opening TA for the command value.

Title: Positive electrode plate for lead storage battery
Inventor: TAKEMASA ARIHIKO
IPC: H01M4/14
Filed: 1990-10-31
Abstract: PURPOSE:To prevent falling-off of active material due to repetition of overcharge and maintain discharge performance over a long period of time by making an active material layer touching a collector in proximity to the collector contain more maintaining material than an active material layer on the surface. CONSTITUTION:An active material layer touching a collector in proximity to the collector is made to contain more maintaining material than the active material layer on the surface. The end of discharge reaction of a positive electrode plate is when Pb SO4 formed by discharge reaction covers the surface of an electrode plate and diffusion of sulphuric acid into the inside of the electrode plate does not catch up. Accordingly, even if the active material layer near the collector contains much maintaining material just like this electrode plate, the discharge reaction is superior to the conventional one and since the active material layer near the collector contains much maintaining material, the particles of the active material are hard to move and even in such a case as overcharge is made, the active material is hard to come off from the collector. Thereby, the falling-off of the active material due to repetition of overcharge may be prevented and the discharge performance over a long period of time may be maintained.
