Title: Scintillator for radiation detection
Inventor: AKIYAMA SEIKICHI
IPC: G01T1/202
Filed: 1981-11-24
Abstract: PURPOSE:To project light emitted from a scintillator upon a photodetector efficiently by coating the surface of the solid-state scintillator with a light reflecting material to a prescribed thickness by a screen printing coating method. CONSTITUTION:The surface of a solid-state scintillator is coated with a light reflecting material to a 50-150mum thickness by a screen printing coating method to obtain a scintillator for radiation detection. When the thickness of said light reflecting material is <=50mum, the light emission output of the scintillator decreases below 90 in terms of the quantity of light to fail in efficient projection on a photodetector, and the light reflecting material is easy to peel off. When the thickness is >=150mum, the thickness of the light reflecting material has variance and becomes uneven, and the total size precision of the scintillator including the light reflecting member is inferior and is hardly incorporated in a device.

Title: Magneto-optical recording medium
Inventor: HORIKAWA MITSUHIRO
IPC: G11B11/105
Filed: 1987-07-29
Abstract: PURPOSE:To improve weatherability and to simplify a production process by allowing a cobalt ferrite layer formed on a hard glass substrate to function both as an information recording layer and as laser light guide layers without forming the laser light guide grooves on the substrate. CONSTITUTION:A photoresist is coated over the entire surface of the hard glass substrate 1 and is prebaked; thereafter, the photoresist is exposed for the laser light guide grooves by a laser beam cutting device and is developed. Post baking is then executed in an inert gaseous atmosphere in such a manner that the photoresist does not sag at the time of forming the cobalt ferrite layer 2. The cobalt ferrite layer 2 is formed by the sputtering method and the photoresist remaining thereafter is stripped. The cobalt ferrite layer is heat- treated in an oxygen atmosphere in order to convert the formed cobalt ferrite to a perpendicularly magnetized film. A reflecting film 3 is then formed by vapor deposition. Since the guide grooves are formed by a lift-off method, the stage for etching the glass substrate 1 by reactive ion etching is decreased. The weatherability is thereby improved and the production process is simplified.

IPC: D01F8/10
Filed: 1987-07-29
Abstract: PURPOSE:To make an optical fiber hard to break even when it is bent by specifying the ratio of the thickness of a clad to the diameter of a core.

Title: Performing bearing method for ball joint
Inventor: HAMAGUCHI YASUNORI
IPC: F16C11/06
Filed: 1985-08-27
Abstract: PURPOSE:To stabilize the swing and rotating torque to complete the bearing of a ball joint in a short time, by applying a predetermined relative load onto a housing and a ball stud to plastically deform a local part of a resin bearing. CONSTITUTION:A bearing 9 made of highly wear-resistant synthetic resin such as, for example, nylon, polyethylene, polyacetal, having a seat surface embracing a spherical head 4 of a shank 3 of a ball stud 2, is fitted into a housing 5, and a close plate 8 is caulked to secure them. Then, the housing 5 is secured, and a predetermined load is applied to the ball stud 2. This load P may be applied in any direction in the case of an integral bearing type, but in the case of a split bearing type, it should be applied in the direction in which the resin bearing is compressed in the load exerted direction. Accordingly, a local material flow occurs in the resin bearing, and the resin bearing uniformly follows the shape of the spherical head 4, thereby it is possible to perform the bearing of the ball joint in a short time.

Title: Integrated circuit for communication
Inventor: ENDO MASAYUKI

Filed: 1989-07-21
Abstract: PURPOSE:To eliminate the need for the provision of an exclusive reset terminal by setting a level different from an intermediate level used normally at communication to at least one of 1st and 2nd terminals connected to a 2-wire communication bus and initializing an internal circuit. CONSTITUTION:When the potential of an least either of a BUS +terminal 13 and a BUS -terminal 14, e.g., the potential of the BUS +terminal 13 is forcibly dropped to 0 level externally, an N-channel MOS transistor(TR) 19 is turned off and the output of an inverter 20 goes to a low level, then a reset signal is inputted to a signal processing section 11, which is initialized. Since it is detected and a reset signal is outputted when the level of at least 1st and 2nd terminals connected to a 2-wire communication bus reaches a level different from an intermediate potential used normally at communication, no exclusive reset terminal is required and the wiring for the purpose is not required and then the wiring is simplified.
