Abstract: A lighting device includes a light source, a board, and a light guide. The light source emits light. The board mounts the light source on a mount surface perpendicular to a light emission surface of the light source. The light guide has an incident surface which the light emitted from the light source enters. The incident surface is opposed to the light emission surface. The light guide extends from the incident surface in a direction of the emitted light and is bent toward an irradiated surface of an irradiation target on a way of the light guide. The board is disposed such that an opposite surface of the board opposite the mount surface is opposed to the irradiated surface of the irradiation target.

Abstract: A light projection unit includes a substrate, a plurality of light emitting elements arrayed on the substrate in a main scanning direction and including light emitting surfaces, a light guide facing the light emitting surfaces to direct light projected from the light emitting elements onto an illumination target and including a first positioning portion, and a holder including a second positioning portion that engages the first positioning portion of the light guide to position the light guide on the holder. The first positioning portion of the light guide is positioned between centers of light emission of adjacent light emitting elements in the main scanning direction of the substrate when the first positioning portion engages the second positioning portion of the holder.

Abstract: In a television receiver having a decryption unit and a video display unit which are stored in one casing, copyright protection is given to an encrypted digital video signal or analog video signal.When an encrypted digital video signal is inputted to a digital video signal input terminal, the signal is decrypted by a decoding circuit to obtain an after-decryption video signal that is copiable, and thereafter, the signal is visualized by a video display unit. When a casing cover is opened, a decoding control circuit converts a parameter that is needed for decryption, such as an encryption key, into a meaningless parameter, and outputs it to the decoding circuit, whereby the after-decryption video signal becomes a video signal that is not decrypted.On the other hand, during maintenance, a predetermined code is inputted from a button group (18) to output a regular decryption parameter to the decoding circuit (13).

Abstract: An elasto-plastic damper is adapted to be used in a structure, such as a building and other facilities, for absorbing vibration energy created by earthquake tremors and other ground vibrations. The damper is a centrally bulged and generally cone-shaped hollow body of revolution so that its section modulus changes substantially porportional to a bending moment created in the damper body due to horizontal stresses, thus permitting a maximum degree of deformability. This elasto-plastic damper is compact in size and demonstrates a high degree of vibrational energy absorbability.

Abstract: A device for compensating for nonlinearity of amplifiers by use of a predistortion principle, and a nonlinear signal generating circuit built in such a device. The nonlinear signal generating circuit includes a quadrature hybrid of the type using a distributed constant line. Two diodes and a terminal resistor are connected in parallel and opposite in polarity to each other and connected between the terminals of coupling and passing ports of the hybrid and ground. The nonlinear compensating device is constituted by the combination of a plurality of quadrature hybrids of the type using a distributed constant line and various kinds of diodes. All the circuit segments of the device are implemented with a planar circuit provided on a single dielectric substrate and diodes which are held in a pair chip condition. Such circuitry is accommodated in a single air-tight housing to complete a microwave integrated circuit.
