Patent JP-S6337705-A (JP)
Title: Light reception circuit
Inventor: FUKUSHIMA KAORU
IPC: H04B10/60
Filed: 1986-08-01
Abstract: PURPOSE:To accurately hold an output amplitude value at a constant value by simple circuit constitution by supplying a constant current to a diode and removing the influence of a dark current by an amplitude limiter. CONSTITUTION:A signal which is converted photoelectrically by an avalanche photodiode (APD) 1 is amplified by a transformer impedance type amplifier 2 and amplified by an amplitude limiter 3 to a prescribed amplitude. A mean current which flows to the APD 1 by a bias circuit 4, on the other hand, becomes an invariably constant current regardless of whether the reception level of a light signal is high or not. Consequently, a simple circuit which has no loop circuit can be widen in dynamic range without making the operation range of the amplitude limiter wide, and the APD bias circuit makes an output signal current value constant by the amplitude limiter if it is not constant, thereby improving the accuracy of the output amplitude value.

Title: Key telephone device
Inventor: SUZUKI AKIRA
IPC: H04Q3/58
Filed: 1986-08-01
Abstract: PURPOSE:To substantially prevent transmission of PB signals produced by operations of keys and therefore giving no unpleasantness to the remote side, by setting a PB signal attenuating circuit into a channel to attenuate the PB signals when keys are pushed. CONSTITUTION:When a holding state is desired for a circuit kept busy with a key telephone set 2, an optional key, e.g., a # key is pushed in a busy mode. Thus a PB signal generating circuit 12 delivers a PB signal corresponding to said key. This PB signal is received by a PB signal receiving circuit 7 and sent to a controller 9. Thus the controller 9 knows that the set 2 is operated for holding and therefore the controller 9 bolds the relevant circuit. Here a PB signal attenuating circuit 4 is put in series with a channel and therefore the PB signals produced with push of the # key are scarcely transmitted to the remote side.

Title: Viscous coupling
Inventor: FUSHIKI MASAAKI
IPC: F16D35/00
Filed: 1992-07-09
Abstract: PURPOSE:To provide a viscous coupling having a small number of part items and so simple a structure as to facilitate assembly and so designed that the gap between plates is kept constant without use of a specific member. CONSTITUTION:A first and second plate 61, 71, which constitute a viscous coupling, both comprise tubular bodies 62, 72 serving as bases and formed integrally with plates, so that members for setting the gap between the plates, such as a spacer ring, can be removed. Therefore, the viscous coupling has a small number of part items and is easy to assemle since the work of integrating a pair of plates can be omitted, and in addition, a hump phenomenon can be prevented since the gap between the plates is constant.

Filed: 1984-09-03
Abstract: PURPOSE:To improve an operational facility of a menu data selecting instruction by simultaneously displaying multiple hierarchies of the menu data and switching and displaying the data of upper and lower hierarchies according to a data selectively specified. CONSTITUTION:An initial screen process is executed by a computer 1 and an initial screen 20 is displayed.

If the factor specified is of the lowest hierarchy, the factor group of the highest hierarchy is deleted and a screen 21 is displayed by shifting the remaining hierarchies to one step higher hierarchies. In succession, a screen 22 is displayed with displaying lower factor group of specified factor to the lowest hierarchy. If the specified factor is of middle hierarchy, a screen 23 is produced by displaying the lower factor group of that factor. When the factor specified is of the highest hierarchy, the factor group of the lowest hierarchy is deleted and the remaining factors are displayed being shifted to one step lower hierarchy, and a screen 24 is displayed with placing the higher factors of the specified factor at the highest hierarchy.

Title: Ship propelling device
Inventor: NISHIYAMA SHIGEKI
IPC: B63H1/28
Filed: 1985-08-22
Abstract: PURPOSE:To improve propulsion performance, by a method wherein a free rotary water turbine, which is of a biaxial propeller type and rotated in the same direction as that of a bilge vortex, is mounted in front of a propeller so that rotation energy of a bilge vortex is rationally recovered. CONSTITUTION:In an enlarged ship type, a pair of bilge vortexes are generated from the right and left boards of the stern during forward sailing. The bilge vortexes are introduced in their respective free water turbines 2, and the free water turbine 2 is rotated in the same direction of the swirl direction of the bilge vortex 12. The wake flow bundle of the free rotary water turbine forms a slip stream having a diameter larger than that of the free rotary water turbine 2, and the stream enters a screw propeller 5. Since each screw propeller 5 is so situated as to rotate in a direction opposite to that of the free rotary water turbine 2, a series of proper dynamic control of the bilge vortex 12, the free rotary water turbine 2, and the screw propeller 5 enables production of a non-rotation slip stream, resulting in improvement of propulsive performance.

Abstract: PURPOSE:To heighten formation charging efficiency and to increase life performance by preparing paste by kneading lead powder containing lead oxide such as red lead oxide with an alkaline solution, then by kneading again them with sulfuric acid. CONSTITUTION:An alkaline solution is used in kneading instead of water which is usually used. Part of lead monoxide contained in lead powder containing lead oxide such as red lead oxide is dissolved in the alkaline solution while paste is kneaded. Sulfuric acid is added to the paste and kneading is continued. The paste obtained is aged and dried. Dissolved lead monoxide deposits on particles of red lead oxide and tribasic lead sulfate monohydrous during aging and drying. Network structure is formed between particles and binding action between active material particles is increased. Softening and coming off of the active material in the early stage are prevented, formation charging efficiency is heightened, and life performance is increased.
