Title: Core for chip coil and its manufacture
Inventor: KASHIWA TOMOO
IPC: B30B11/00
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To easily remove burrs by barrel finishing by forming a flank continuously entering the surface of a wound core toward the flange side by a specified length, and extended outward from the wound core in both directions perpendicular to the axis of the wound core. SOLUTION: A flank 21 is formed on a core 1 which flank continuously enters the surface of a wound core 2 toward the flange 3 side by a specified length and is extended in both directions perpendicular to the axis of the wound core 2. During press molding, burrs 81 and burrs 82 are formed on the wound core 2 and the flank 21, respectively, in the gap between a stamping die and a cavity die. A plurality of molded or sintered cores 1 are fed into a barrel and subjected to barrel finishing. At this time, the burrs 81 are completely protruded from the ridge of the core 1 to both ends in the direction of the length of the wound core 2 due to the presence of the flank 21, and other cores and abrasives are apt to collide with the burrs 81. Though the other burrs 82 may be sometimes left unremoved, they do not damage the covering layer of coil wires because of their relative positions.  As a result, barrel finishing is facilitated.

Title: Receiving equipment
Inventor: IWATA SHINICHI
IPC: H04N5/44
Filed: 1991-11-12
Abstract: PURPOSE:To improve the operation convenience by providing separately input terminals of a BS signal and a TV signal, and facilitating an external output of the BS signal integrated into a VTR. CONSTITUTION:At the time of receiving a TV signal, the TV signal is inputted from a TV signal input terminal 4, amplified by a TV signal input circuit 7, and thereafter, becomes an intermediate frequency signal by a frequency converting circuit 8, and is demodulated by a TV signal demodulating circuit 11. On the other hand, at the time of receiving a BS signal, the BS signal is inputted from a BS signal input terminal 2, and inputted to a distributing circuit 5. The circuit 5 distributes the BS signal into two, outputs one of them from a BS distributing signal output terminal, and sends the other to a BS signal circuit. The signal amplified by a circuit 6 becomes an intermediate frequency signal by a circuit 8, and is demodulated by a demodulating circuit 10. In this case, since the input terminals 2, 4 are separated in advance, it becomes unnecessary to attach a mixing circuit. In such a way, at the time of integrating into a VTR for receiving the BS signal and the TV signal, the operation convenience can be improved.

Title: Production of optical master disk
Inventor: TERASAKI HITOSHI
IPC: G11B7/00
Filed: 1988-12-20
Abstract: PURPOSE:To improve the positive and negative symmetry of a remodulating light signal by changing the duty correction rate to be applied on a modulating light signal according to a change in the linear speed of a circular substrate which rotates at a specified angular speed. CONSTITUTION:The circular disk substrate which rotates at the specified angular speed is irradiated thereupon with modulating light signal subjected to the duty correction by which information is recorded thereon. An optical disk is produced by using such substrate as a master disk. The duty correction time quantity t of the modulating light signal is so adjusted that the correction time quantity of the positive signal of the modulating light signal decreases gradually with an increase in the distance R from the center of the master disk up to the exposing part, i.e. as the exposing position is nearer the outer periphery when the angular speed is constant. Namely, the relation t.R=r is obtd. when the stop diameter of laser light is designated as r and since r is a fixed value, the duty correction time quantity t is made inversely proportional to the distance R, i.e. a change in the linear speed of the disk. The positive and negative symmetry of the remodulating light signal is improved over the entire circumference of the disk in this way.
