Inventor: TAJIRI TAKASHI
IPC: G11B15/467
Filed: 1990-07-30
Abstract: PURPOSE:To add a scramble function at a low cost by recording a phase servo signal indicating an azimuth state different from an actual one in the recording mode of a scramble mode. CONSTITUTION:The heads HA and HB are fixed at the positions opposite to a drum 1 by 180 deg. and have different azimuth angles, that is, these heads are set at A and B azimuth angles respectively. Then both heads HA and HB scan alternately a tape 2, i.e., a recording medium to perform the azimuth recording operations. When a scramble mode is selected for recording, a pilot signal generator 4 outputs a pilot signal of f2 or f4 at the H level of a switching pulse and a pilot signal of f1 or f3 at the L level of the switching pulse respectively. Thus the pilot signals of f2 and f4 are recorded at the A azimuth angle together with the pilot signals of f1 and f3 recorded at the B azimuth angle respectively.

Title: Supporting device for measuring device for mechanical impedance of human body
Inventor: TERADA HARUHIRO
IPC: A61B5/103
Filed: 1981-12-15
Abstract: PURPOSE:To maintain the static load upon a human body always constant by providing a touching part for dispersion of force which is roughly flush to the opening plane in the opening part of a supporting body contg. and supporting a measuring device freely movably in an oscillating direction and has a wide area. CONSTITUTION:The mechanical impedance of a human body 8 is measured with a measuring device A by exerting specified static load upon said body from the upper part of the device A. If downward force is exerted in the axial direction of an exciter 3, the force to be exerted upon the body 8 is divided to the route where the force is exerted through the magnet 4 and sensor block 5 of the exciter 3 and the route where the force is exerted through a touching part 2 for dispersion of force from a supporting body 10. Since the bottom surface of the block 5 projects to the body 8 side from the part 12 and the area on the touching surface of the part 12 is large, the force is dispersed by the part 12 even if the magnitude of the force to be exerted upon the device 8 changes, thus always specified force is exerted at all times upon the block 5; therefore, the static load is determined only by the difference in height between the bottom surface of the block 5 and the part 12.

Filed: 1992-07-07
Abstract: PURPOSE: To improve the throughput of a common communication channel. CONSTITUTION: In this method for transmitting data, data are transmitted to a main station 1 from a plurality of substations 3 through a common communication channel. The communication channel is subdivided into time slots having such a length and synchronization that are decided by the time slot of a data transmitting signal sent from the main station 1. Each substation 3 has a prescribed probability (p) for transmitting a data packet in each time slot. The throughput of the communication channel can be improved when such an arrangement is made that the next time slot (n+j) can always be reserved so that the time slot (n+j) can be used exclusively by a specific substation 3 when the main station 1 properly receives a data packet sent from a specific substation 3 in a specific time slot (n).
