Title: Signal processor
Inventor: NOJI MINORU
IPC: H04N5/208
Filed: 1986-12-15
Abstract: PURPOSE:To prevent the occurrence of the blur of a color, and to improve a picture quality by generating and outputting an information signal by means of using selectively the outputs of a delaying means and a holding means, synchronizing with a level fluctuation timing detected by a detecting means. CONSTITUTION:The output signal X of a voltage comparator 30 is inputted to a switching pulse generator 31, and a pulse X2 is obtained by a NOT gate 31-4, an AND gate 31-6 and a delay circuit 31-7. When a switching pulse Z, which is obtained from the rise-up of the pulse signal X by a differentiation circuit 31-8 and has the pulse width of a very small time, is at a high level, analog switches 12 and 14 come to a close state, and simultaneously the pulse signal X2 passes through an OR gate 31-3 and puts the analog switches 11 and 13 into an open state. The potential E of a voltage holding condenser 15 is the potential of a signal Ui, fetched by the signal Z, and is held for the duration of the pulse X2. A color difference signal Uo, which rises up steeply at the middle point of the rise time of a delayed color difference signal B, is obtained by the composition of these operations. Thus, the blur of the color, caused by the delay of the rise time of an input color difference signal Ui, can be prevented.

Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To shorten a process and to prevent a defective wiring board or drop of adhesive strength by allowing the surface of a resin base material roughened by wet blast to be conductive using a palladium catalyst, and applying an electrolytic plating on the surface of the conductive resin base material.

Title: Opticla limiter circuit
Inventor: HIRANO AKIRA
IPC: G02F1/015
Filed: 1994-12-01
Abstract: PURPOSE: To provide an optical limiter circuit which operates with small light intensity and is high in response speed and with which a fluctuation in the light intensity of small amplitude is removable by providing one of branched optical waveguides with a specific saturable absorber and superposing guided light in antiphases on each other. CONSTITUTION: The optical waveguides 12, 13 formed on a substrate 10 separately guide the incident light rays branched at a prescribed ratio by an optical demultiplexing part 11. Transmittance increases sharply when the incident light intensity exceeds the threshold value. For example, the saturable absorber 14 of InGaAs/ InAlAs based multiple quantum wells doped with Be by low-tap. growth is arranged in the optical waveguide 12 and the optical demultiplexing part 15 superposes the light rays guided by the optical waveguides 12, 13 in the antiphases at the prescribed ratio. As a result, the exit light intensity of the optical limiter circuit is made constant where the incident light intensity exceeds the threshold value. The threshold value of the optical limiter circuit is arbitrarily set by changing the branching ratio of the light by the optical demultiplexing part 11.  The threshold characteristic is obtained with the correspondingly smaller power if the intensity of the light heading toward the saturable absorber 14 is increased.

Title: Flexible plate mechanism
Inventor: DOUMAN TAISUKE
IPC: F16F15/129
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To sufficiently damp bending vibration from the engine side by providing a disk-shaped plate to be elastically deformed in the bending direction and a mechanism to frictionally slidingly move by bending directional deflection of this plate. SOLUTION: In this flywheel assembly 1 and a clutch device 2, torque from an engine is transmitted to a flywheel 3 through a flexible plate mechanism 20. At this time, when a crankshaft 6 is bent (in the V1 direction) by combustion force of the engine, the flexible plate mechanism 20 is elastically deformed in the beinding direction (the V2 direction). For example, in a condition where a first flexible plate 8 and a second flexible plate 9 deflect, a friction washer 10 is deformed between the first and the second flexible plates 8 and 9, and frictionally slidingly moves on both members. In this way, the respective plates are elastically deformed, and when friction is further, bending vibration is effectively damped.
