Title: Production of magnetic head
Inventor: KURAKANE KIYOSHI
IPC: G11B5/127
Filed: 1984-02-24
Abstract: PURPOSE:To obtain a magnetic head having high reliability by attaching a glass material to junction faces of two core members together with a glass material of a low fusing point provided to one of both core materials to bond both core members by heating and furthermore fusing a reinforcement glass to the junction face to increase the bonding intensity. CONSTITUTION:A gap layer 20 of a high fusing point is formed to the gap forming surfaces 2 and 3 of core members 1 and 5 respectively. In addition, a gap layer 21 having a fusing point lower than the layer 20 is formed to the member 1. The total strength of these layers 20 and 21 and the member 1 is set equal to the desired gap width. Then both members 1 and 5 are bonded together with pressure, and the layer 21 is heated and fused to bond the core members. A reinforcement glass material 22 equal to that of the layer 21 is set at a place near the press-contact part of the face 2 and fused by heating. Thus the bonding intensity between the paired members 1 and 5 is increased. This produces no crack to a gap part even when the head front part is ground nor gap shift when a magnetic head is used. Thus the reliability of the magnetic head is improved.

Abstract: PURPOSE:To avoid the erroneous stoppage and the unstable accuracy of a sweep receiver, by providing an oscillator oscillating the same frequency as an intermediate frequency signal and producing a sweep stopping signal from the intermediate frequency and the beat component of the oscillating frequency. CONSTITUTION:A local oscillating part has a PLL consisting of a crystal oscillator 14, a frequency multiplier 15, a phase comparator 16, a 1/n frequency divider 17, an LPF18 and a VCO19.

Title: Protecting circuit for firing lamp
Inventor: FUKUSHIMA OSAMU
IPC: H02H9/02
Filed: 1988-02-17
Abstract: PURPOSE:To protect a lamp against a rush current and to suppress the deterioration of a thermistor by closing a normally open contact provided in parallel with the thermistor connected in series with the lamp after a predetermined time is elapsed from the time of initiating to fire the lamp. CONSTITUTION:A fuse 16, a lamp 12 and a thermistor 18 are connected in series with an AC power source 14A. Bypass circuits 22, 23 are composed through a normally open contact 20 at the thermistor 18. The contact 20 forms a relay circuit 24 to be energized by a coil 26. When the lamp 12 is fired, a small current flows from the power source 14A by the negative resistance of the thermistor 18 to suppress the rush current of the lamp 12, and a small current also flows to the coil 26. The current increases upon rising of the temperature of the thermistor 12. When the current of the coil 26 rises at a predetermined value or more, the contact 20 is closed to short-circuit the thermistor 18, thereby supplying a predetermined current to the lamp 12. Thus, the lamp 12 is protected against the rush current, thereby preventing the thermistor 18 from consuming.

Abstract: PURPOSE:To stably control tension of a tape or a thread by detecting the displacement of a dancer roller only once a turn of a rotary unit by a ground side contactless sensor holding the detected value and controlling a rotary speed of a driving motor by this holding signal. CONSTITUTION:A detecting piece 7a of a dancer roller 7 passes through a detecting area of a distance sensor 9 once a turn of a rotary unit 1, and detecting a change of the dancer roller 7 by the distance sensor 9 only one moment of the passing, a signal holding circuit 11 holds a detecting value of the sensor 9 till the next time detection.
