Title: Displacement amount detector
Inventor: NAKAMURA SHIGEKAZU
IPC: G01D5/14
Filed: 1983-06-17
Abstract: PURPOSE:To make it possible to detect magnetism accurately without the effect of magnetic fields of noise, by arranging two sets of magnetism sensors, which are magnetically biased in the reverse directions to each other with the phase difference of 180 deg. being provided with respect to a magnetizing pattern. CONSTITUTION:Magnetoresistance elements Ra1, Ra2, Rb1, and Rb2 are laminated so as to hold insulating films and magnetically biased in the reverse directions each other in two sets of magnetism sensors. The magnetism sensors are aligned in the direction, which is perpendicularly intersected with the arrows of the displacing direction and mounted on a common substrate S. The aligning direction and a magnetizing pattern are relatively inclined in the direction perpendicular to the direction of the arrow. The phase difference of about 180 deg. is imparted to the magnetism sensors with respect to the magnetizing pattern, and bridge connection is performed. The magnetic fields of noise of the two sets of the magnetism sensors are offset, and only the output of the magnetizing pattern can be obtained.

IPC: B60R13/04
Filed: 1991-05-14
Abstract: PURPOSE:To provide a double side-coated tape capable of easily removing an attached body if necessary while ensuring an adhesive force of a bonding agent layer. CONSTITUTION:While a side molding 2 has an embedding part of a thready body 12 embedded integrally therein, extending stepwise longitudinally over the almost total surface of a bonding agent layer 11 for bonding the side molding 2 to the side of a car body 1, both ends of the thready body 12 are exposed from both longitudinal ends of the bonding agent layer 11 to the outside.

Title: Automatic af signal decision circuit
Inventor: HAYASHI NOBUYOSHI
IPC: G11B20/00
Filed: 1983-06-15
Abstract: PURPOSE:To improve the detecting accuracy in comparison with a conventional example detecting the average level of a signal transmitted to an AF signal band by detecting the difference of a level at a period corresponding to a vertical synchronizing period in a signal included in the said AF signal band to decide the presence of the AF signal. CONSTITUTION:A video signal and an AF signal are led in the output of an extracting means 1 and when a conventional tape on which no AF signal is recorded is reproduced by a band pass filter 2 passing only the AF signal band component, the video signal (leakage signal) is outputted. A gate signal forming circuit Q forms a gate signal displaying a period T corresponding to the vertical synchronizing period of the video signal using the PG pulse from a PG generator 15 as a reference. a gate circuit 3 receives the output of the filter 2 and outputs an intermittent signal high in level at the input of the AF signal by the said gate signal and outputs an intermittent signal low in level at the input of the leakage signal. The output of a rectifier circuit 4 is compared with a reference potential being a negative input by an operational amplifier 41, which outputs high level signal at the input of AF reception and outputs a low level signal at the input of leakage signal.

Title: Switching circuit of magnetic head
Inventor: SEKIMOTO KUNIO
IPC: G11B5/02
Filed: 1982-06-22
Abstract: PURPOSE:To attain complete insert edition without the lack of a signal by applying a fixed negative potential to an input terminal at the time of recording to make recording current flow into a magnetic head without distortion and switching recording and reproducing status without transient phenomenon. CONSTITUTION:At the time of recording, -E2 potential is applied to a terminal 9a as shown in the figure. Therefore, the potential of the base D point of a transistor (TR) 10a is -E2R2/(R1+R2). If signal voltage applied between points A and B at the time of recording is 5.0Vpp, the negative peak of the point is -2.5V. If VBE=0.7V in the TR 10a, the TR 10a is prevented from being connected at the time of recording by setting up -E2 so that the base potential is -(2.5-0.7)=-1.8V or less. At the time of reproducing, E1 potential is applied to the terminal 9a and the TR 10a is turned on. Since the points A, B are ''0'' potential always at the time of recording and reproducing, transient phenomenon is not generated at the switching of the recording and reproducing as shown in waveforms A, B and complete insert editing can be attained without the lack of a signal.
