Abstract: A television receiver and a signal receiving method thereof includes a terminal for connecting the television receiver to a personal computer for inputting information from the personal computer to the television receiver, a display for displaying a television signal, an input operation means, such as a remote controller, for generating a command signal, and a controller supplied with the command signal for controlling the personal computer and for inputting the information from the personal computer through the terminal to the television receiver for converting the television receiver from a television mode to a personal computer mode for displaying the information on a screen of said display. Advantageously, the personal computer and the television receiver are controlled by a command signal from the input operation means.

Abstract: A deflection yoke mounted on a television picture tube comprising:a horizontal deflection coil, a vertical deflection coil, a core disposed outside the horizontal deflection coil, and a separator extending completely between the horizontal deflection coil and the vertical deflection coil for isolating the horizontal deflection coil from the vertical deflection coil, the separator being entirely comprised of a mixture of plastics and granular ceramics having a high thermal conductivity wherein a resinous material having a high thermal conductivity is filled in spaces between the picture tube and the horizontal deflection coil, the horizontal deflection coil and the separator, the separator and the vertical deflection coil, and the core and the vertical deflection coil so as to bond and fix the deflection yoke to the tube and form a heat transmission passage in the spaces, whereby heat produced in said horizontal and vertical deflection coils is reduced even when they are scanned with a large current of a high

Abstract: A deflection yoke mounted on a television picture tube comprises a horizontal deflection coil, a vertical deflection coil and a separator for isolating the horizontal deflection coil from the vertical deflection coil, wherein the separator is a molded product of a mixture of plastics and granular ceramics having high thermal conductivity.

Abstract: An improved corner shear machine including a recess which extends toward a ram across a table so that a tool assembly unit comprising a combination of a punch and a die is removably fitted into the recess. The die is firmly included in a die block and the punch is fixedly secured to a punch block, whereas the punch block is vertically displaceable toward or away from the die block with the aid of a pair of symmetrically located guide pins which stand from the latter at the rear part thereof. To allow the punch to resume the original position after completion of a shearing operation a resilient means is arranged in a suitable position in the tool assembly unit, and moreover to prevent a workpiece in the form of a sheet material from being raised up together with the punch after completion of the shearing operation a plurality of symmetrically located resilient means with stopper means fixedly secured to the lower end thereof are suspended from the punch block.

Abstract: A new and unique workpiece locating device for a corner shear machine which serves for determining a required position prior to starting a shearing operation when it is to be conducted at a corner or on one side of a workpiece in the form of square or rectangular sheet material. The workpiece locating device includes a pair of symmetrically located grooves extending in a V-shaped form relative to a center line extending through the center of dies across a table and a pair of rotary stoppers displaceably mounted on said grooves so as to slide to and fro therealong. The workpiece abutment edge of the respective stoppers is adjustable within an extent of an angle of 45 degrees in both the rotational directions relative to a plane extending at a right angle to the cutting edge of the dies. Measuring scales for both corner shearing and side shearing are fixedly mounted on the table in the vicinity of the grooves and in parallel to the latter.
