Abstract: PURPOSE:To enable forward rotation and reverse rotation to be repeated without causing a film to sag, by a construction wherein take-up and rewinding spools are connected to driving shafts through sliding clutches, respectively, and the driving shaft on the payout side is fixed. CONSTITUTION:The sliding clutches 8a, 8b provide appropriate sliding frictional forces through disks 10a, 10b and spring mechanisms 9a, 9b. When a rotational torque of not less than a fixed value is applied to the driving shaft on the driving-side 14a (in the case of forward rotation) or 14b (in the case of reverse rotation), the sliding clutch 8a or 8b performs sliding rotation, thereby transmitting a fixed rotational torque to the driving-side spool 2 or 1. On the other hand, the payout-side spool 1 or 2 is fixed by the clutch 8b or 8a, so that the relevant clutch applies a tension to the driving-side through the film 7, and applies a tension as a braking force when stopping the rotation. Accordingly, the response properties of the driving-side spool and the payout-side spool are enhanced, and the film is prevented from sagging.

Title: Control unit of hydraulic operating type transmission for vehicle
Inventor: NISHIMURA SADANORI
IPC: F16H61/18
Filed: 1983-03-11
Abstract: PURPOSE:To secure buffering time at a low opening range without any increase in the capacity of an acculator, by decompressing the input pressure fed to an orifice in the low opening range of throttle opening. CONSTITUTION:A pressure-reducing valve 20 operating to be inputted into each of orifices 14 and 15 after decompressing the line pressure fed out of a pressure- regulating valve 8 is installed in a way of interposing in a second oil passage L2 at the upstream side of a shift valve 10.

Title: Magneto-optical recording medium
Inventor: ICHITANI KATSUMI
IPC: G11B11/105
Filed: 1993-02-04
Abstract: PURPOSE:To maintain signal characteristics when reproducing is done at high temp. or continuously repeated by forming a protective film between a substrate and a recording film in such a manner that the protective film has 0.15-0.25nm surface roughness of the surface adjacent to the recording film. CONSTITUTION:A protective film is formed between a substrate and a recording film. The surface roughness of the protective film in the recording film side is 0.15-0.25nm. If the surface roughness is smaller than this range, reproducing durability decreases. If the roughness is larger, signal characteristics decrease. First, a protective film SiAln is formed on a polycarbonate substrate, then a TbFeCo recording film and a second protective SiAln film are formed, and a reflecting film AlTi is formed thereon. The surface roughness of the protective film can be controlled by pressure during forming, and under the higher pressure for film forming, the more rough surface is obtd. By this method, deterioration of signal characteristics is decreased even when the medium is used at high temp. or for continuous reproducing.

Patent JP-H02217270-A (JP)
Title: Image forming head
Inventor: HANDA TSUNEO
IPC: B41J2/395
Filed: 1989-02-20
Abstract: PURPOSE:To make uniform a potential on the surface of an image forming member across the entire surface of said member and minimize the deterioration in print quality by allowing electrodes separated from each other for the formation of a latent electric charge image to come in contact with a common electrode before the passage of the image forming member through the electrodes. CONSTITUTION:An image forming member first touches a common electrode 2 when coming in contact with an image forming head, and controls a potential on the entire surface of the member to a specified value. After this, the member comes in contact with an electrode for image formation 3. After its passage through the electrode, the image forming member has an electric charge image formed on the surface. Then an image development process takes place, for the visualization of the electric charge image. If the case occurs that the surface of the member comes in contact with an insulating or a conductive member during the above-mentioned process, the electric charge image is disturbed. Therefore, the thickness of each electrode needs to be controlled, that is, the electrode for image formation 3 must protrude from the surface of an insulating substrate 1 more outstandingly than the common electrode 2. This allows the image forming head to tilt against the image forming member. Consequently, the image forming member passing through the electrode for image formation 3 is displaced away from the substrate, so that the electric charge image can be prevented from being disturbed.
