Abstract: A light source system in which light scattered inside a chamber (2) exits from a hole (3) to provide a light output from the system. The interior wall of the chamber (2) consists of a material which is very efficient at scattering incident light. Light emitted from a light source (1) undergoes at least one scattering event within the chamber (2) before escaping from the chamber (2) through the exit hole (3). Any geometrical attributes of the light from the source (1) are removed before the light exists from the chamber (2). The exit hole (3) can have a tube inside (4) and/or outside (5) the chamber (2) for collimating the light output. A mechanical shutter (7, 8) can be used as a simple dimmer mechanism for the light output from the system. The light source (1) can be positioned inside or outside the chamber (2).

The bearing member has a groove portion formed on a longitudinal center portion of an outer periphery thereof so as to form flange portions abutting against an inner periphery of the roller member in both longitudinal sides of the groove portion. The diameter of portions of the inner periphery of the bearing member where oppose to the flange portions are enlarged than the diameter of a portion where opposes to the groove portion.

Abstract: An optical disc apparatus includes a turntable. The turntable is first rotated at a low speed in response to turning on of a reproduce switch on the disc apparatus, and the balancer is, in turn, brought to rest at an optimal position for low speed rotation. When the balancer comes to rest, automatic adjustment is effected. When the automatic adjustment is ended, the turntable is decelerated in rotation to release the balancer from resting. When the rotation speed of the turntable reaches a speed at which the balancer is released from resting, the balancer becomes movable relative to the turntable. Thereafter the turntable is brought into high speed rotation to move the balancer to rest at an optimal position for high speed rotation.

Abstract: A control system for transmission devices equipped with a high-efficiency coding scheme in a communication network which avoids degradation of the quality of an acoustic signal for transmission and permits an efficient transfer of the acoustic signal. The control system has a structure in which: information on a high-efficiency coding scheme used in the preceding transmission device is sent to the current exchange from the preceding one through the use of an out-band signaling system for transmitting and receiving a call control signal via a channel different from a speech channel; and based on the information sent to the current exchange, second-placed transmission devices connected to the current and following exchanges avoid effectively decoding/coding of the acoustic signal transferred thereto, or the use of these transmission devices is avoided.

Abstract: A plurality of layers having other resolution are coded in order to encode scalably shape information. A base layer having the lower resolution is coded and transmitted to a decoder, and an enhancement layer is coded by employing a scan interleaving method from the base layer. A scan order of vertical and horizontal scannings is decided according to a generation frequency of TSD (transitional sample data) and ESD (exceptional sample data) and the number of coding bits on the base layer, or a type of boundary lines on images. When the scan order is decided, additional information indicating the scan order is transmitted to the decoder. The base layer is also coded and transmitted to the decoder. In case that the scan order is decided according to the horizontal and vertical of the boundary lines on an image of the base layer, it is no need to transmit the additional information indicating the scan order on the received base layer and execute the decoding in the same order as the coded scan order.

Abstract: A program-viewing inhibition device comprises a memory for storing inhibition level data indicative of a predetermined level of unsuitability rating of a broadcasting program, a control section for determining whether or not an input channel received is acceptable by comparing inhibition level data extracted from a broadcast signal of an received input channel with the inhibition level data read out of the memory, and for changing the input channel to another channel when it is judged that the input channel is unacceptable or to be rejected for its viewing. Accordingly, a manual operation to change the input channel to the substitute channel when the input channel is unacceptable for viewing can be eliminated.

Abstract: An adjustable safety utility knife includes an elongated ergonomically shaped handle formed of two elongate shell members each having a peripheral edge and an outer generally convex surface and an inner generally concave surface. The shell members are fastened at the peripheral edges along a vertical parting plane to form an elongated internal cavity. The handle defines a front end, a back end and an intermediate portion suitable for being gripped by a user and also defining top and bottom surfaces extending along opposite sides of the shell members along the peripheral edges. The handle has a slot-like aperture at the front end substantially aligned with the parting plane and dimensioned for passage of a flat cutting blade therethrough. A guide element within the elongated cavity guides the cutting blade between a first position for safely storing the blade fully inside the cavity and a second position for selectively extending the blade beyond the aperture to expose at least a portion thereof.
