Title: Call system of multi-channel access system
Inventor: OOHAYASHI ARATA
IPC: H04W4/06
Filed: 1983-11-25
Abstract: PURPOSE:To improve the effective usage ratio of a call channel, to save the trouble of recall and to improve the operability by performing general calling to all the compound stations and mobile stations in the group when a response signal from the opposite station is not detected after an individual call ends. CONSTITUTION:When the reception of the response signal cannot be confirmed even after fixed time passes, the individual call signal is sent up to maximum N times including the 1st individual call, and the reception of the response signal is decided for each of these individual calls. When the response signal is detected with respect to the N-th individual call, general calling number signs stored beforehand are outputted and the general calling is executed. Namely, CPU19 first sets the call counter to ''M'' and then the general calling signal is sent by repeating M times at fixed intervals. The M is a frequency which is set beforehand. When M-th sending ends, the call condition is obtained. Namely, when the response signal from the opposite station is not detected with respect to the individual call, the general calling is executed instantaneously and automatically.

Title: Thin film magnetic head
Inventor: MIYAUCHI SADAICHI
IPC: G11B5/31
Filed: 1990-08-23
Abstract: PURPOSE:To suppress the generation of a Barkhausen noise of a reproducing waveform by constituting the magnetic head so that magnetization of a thin film magnetic core in the vicinity of a magnetic gap responds linearly by a rotational magnetization mode in the magnetization difficult axis direction. CONSTITUTION:On the opposed surface 4S to a magnetic recording medium of a thin film magnetic coil 4, a projecting part 16 is formed in a tapered shape from the track width direction, that is, the T direction. In this case, even in the projecting part 16, as well, its magnetization is formed by following the magnetization of a magnetic thin film part 4A, therefore, an axis of easy magnetization in the projecting part 16 becomes the Y direction, and the magnetic wall does not fall into disorder. In such a way, since the magnetic head is operated by a magnetization rotation in the X direction of the thin film magnetic core 4 in the vicinity of a magnetic gap 9, the magnetic permeability does not deteriorate, and generation of a Barkhausen noise can be suppressed.

Title: Channel signal loopback circuit for primary group interface
Inventor: NAWA TOSHIHIKO
IPC: H04J3/14
Filed: 1989-08-28
Abstract: PURPOSE:To form a channel signal loopback group of a primary group interface with a small hardware scale by providing 2 selectors, a register and a time slot counter. CONSTITUTION:A channel number data setting a channel to be looped back among channel signals of a primary group interface IF to an H level is written in a register 2. The written channel number data is sent to a selector 3. The selector 3 selects sequentially a sent channel number data with an input representing each time slot from a time slot counter 4 counting the channel number of the primary group interface IF repetitively in the frame timing period synchronously with the signal time slot of the primary group interface IF, receives the signal from the primary group interface IF to be sent as the loop signal and the received signal of the primary group interface 1F, outputs selectively the channel signal from the received signal of the primary group interface IF as the transmission signal by using the loop signal of H level as the transmission signal and applies it to the selector 1 as the loopback signal. Thus, since a register is used in place of a 2-plane of video RAM, the scale of the hardware is reduced.

Abstract: PURPOSE:To obtain a uniform high frequency magnetic field by a method wherein a heterogenous metal of symmetrical structure having high resistance is provided at the symmetrical position in the vicinity of the intermediate point of a high frequency coil, thereby enabling to almost equalize the current of each coil. CONSTITUTION:A heterogenous metal (stainless steel for copper, for example) of symmetrical structure is inserted in the crossing point 3 located in the vicinity of the intermediate point of an oval coil 1, the RF current which forms an RF magnetic field by the resistance value of the heterogenous metal is controlled, and the symmetrical property of the device is maintained. Instead of the heterogenous metal, the resistance value of the coil 1 may be increased by reducing the cross-sectional area of the coil 1. The insertion of the coils 1 and 2 into the part in the vicinity of terminals 4, 5, 6 and 7 is inappropriate due to having adverse effect of the irregularity, asymmetrical structure and floating capacitance of the part located in the vicinity of the terminals. According to this constitution, the current of each coil can be equalized, thereby enabling to obtain the uniform high frequency magnetic field.
