摘要:
An automatic station searching device for a radio receiver in which the order in which the station data is stored in a memory device can be altered so that the user can easily selected between storage in the order of signal strength or storage in the order of frequency. Frequency and signal strength data for received stations are stored in order of signal strength during the sweeping operation. At the end of the sweeping operation, the data are rearranged in order of frequency if a memory bit has been set to so indicate.

A signal receiving system for a TV receiver incorporates at least two independent front end circuits for frequency-converting antenna signals to a lower frequency, with the output signals from these front end circuits being utilized separately to derive the video and audio signal components of the TV signal. Independent control of AGC applied to the audio and video signal components respectively can thereby be implemented, or, in the case of diversity reception using two or more antennas, the optimum antenna for reception of the video and audio signal components respectively can be selected in a mutually independent manner, to thereby attain substantially improved diversity reception, e.g. for a TV installation in a moving vehicle.
摘要:
A multiplex sound receiver in which a detection signal is extracted from a broadcast to indicate whether the broadcast is monaural, stereo, or multi-lingual. The detection signal is used for controlling the separating of the channels. According to the invention, the detection signal is processed in accordance with the strength of the broadcast or the noise level. For instance, the detection signal is integrated over a period that is increased when the field strength decreases.

An illumination apparatus for an endoscope is provided at the distal end of the insertion section of the endoscope. The apparatus has a light guide which extends through the insertion section, has a light-issuing end located adjacent to the distal end opening of the insertion section. The light guide conducts light beams emitted from a light source device. An optical element made of a light-permeable material is arranged to face the light-issuing end of the light guide, and a lens is arranged in the distal end opening. The optical element has a light-receiving surface facing the light issuing end and a light issuing surface opposite to the lens. A depression is formed in the center of the light-issuing surface. Light beams emitted from the end of the light guide pass through the optical element and lens, and are distributed by the depression in the annular pattern whose central portions grow dark and whose peripheral portions are rendered bright.

In the disclosed camera, film is continuously wound from the shaft of a film magazine loaded in the camera onto a spool in the camera, and then exposed frame by frame as the film is rewound into the camera. A motor drives either the spool or the magazine shaft on the basis of the direction of current therethrough and a detector detects loading of the magazine and changes the direction of the power supply to the motor from a condition for driving the magazine shaft to a condition for driving the spool.
摘要:
In a camera capable, upon actuation of a film rewind release member, of cutting off the manual or motorized driving torque from the winding transmission system to render the winding operation impossible, while simultaneously rendering the manual or motorized rewinding operation possible, the rewinding device is provided with means responsive to the actuation of the film rewind release member for cutting off the various charge mechanisms from the manual or motorized driving torque transmission system.

In an automatically focusing camera, the lens is driven to infinity during film winding and the film winding spool is blocked when film winding is completed. Upon shutter release actuation of the camera, film winding is unblocked when the automatic focusing circuit energizes a first magnet and lens rotation is blocked at the focused position when the automatic focusing circuit energizes a second magnet. A single control member operates to effect blocking of the film winding mechanism and to drive the lens to infinity when rotated in one direction, and to unblock the film winding mechanism when rotated in the opposite direction.

A method for manufacturing non-oriented electrical steel sheet and strip having no ridging characterized in that, non-oriented electrical steel sheet and strip is manufactured by casting molten silicon steel into a slab, hot-rolling, cold-rolling and annealing, said molten silicon steel, being controlled so as to give a composition, at the time of hot-rolling, comprising C 2.0% and also C .gtoreq. 1/100 [(Si + Al) - 0.75]% with the remainder being iron and unavoidable impurities.
摘要:
Example systems and methods relate to a video game in which multiple players each supply inputs to a respective input device to control a corresponding game character in a game world. Movements and actions of each game character are controlled in accordance with respective first game character control operations during the playing of the video game. If one of a plurality of conditions is satisfied by one of the players, the one player's game character is protected from harm in the game world. Movements and actions of the protected game character are controlled in accordance with a second game character control operation. The protecting of the one player's game character is stopped in response to one or more protecting stopping conditions, whereby the game character is again controllable in accordance with the first game character control operation.
