Title: Manufacture of resin magnet structure
Inventor: YAMASHITA FUMITOSHI
IPC: H01F41/02
Filed: 1987-09-30
Abstract: PURPOSE:To remove obstacles for the implementation of a compact annular magnet characterized by a thin film and light weight and to manufacture a resin magnet structure, whose assembling property is improved, by compressing the composite material of the raw material of the magnet and a binder in a metal mold, and forming a unitary body together with a supporting member, to which a bonding film is brought into contact tightly at the same time. CONSTITUTION:An annular supporting member 7 in close contact with a bonding film 8 is mounted on a lower floating core 4. The annular supporting member 7 and the lower floating core 4 are lowered when an upper floating core 5 is lowered. Then granulated powder composite material 9 in a cavity is compressed into high density by the descent of an upper punch 6 and the lifting of a lower punch 3. At this time, the pressure is also applied to the bonding film, which constitutes a part of a cavity surface when the high density of the granulated powder composite material 9 is implemented so as to obtain high adhesion. The granulated powder composite material 9 becomes a compressed and solidified green body 10 by the achievement of the high density. At the same time, the material 9 is compressed and bonded to the bonding film 8. Then, the green body 10 is released by the descent of a die 2 and the lifting of the upper punch 6 and the upper floating core 5. Thus, the annular resin magnet, which forms a unitary body together with the annular supporting member, is obtained by the above described steps.

Title: Rotary encoder
Inventor: FUNAKOSHI HIROMASA
IPC: G05D3/12
Filed: 1987-09-30
Abstract: PURPOSE:To obtain a highly accurate apparatus having simple constitution, by detecting the change in magnetic flux density generated by the passage of line of magnetic force escaping a superconductive substance as a pulse signal by a magnetic detection element. CONSTITUTION:Superconductive substances 9 are deposited to the circumferential surface of a rotary body 8 constituted of a magnet at an equal interval by vapor deposition, sputtering or printing. In this constitution, when the substances 9 are allowed to be present in a magnetic field, said substances 9 generate the same state as such a state that a magnet is generated by minus effect and function so as to negate an external magnetic field and to push out the line of magnetic force from the outside to both ends. Hereupon, a change in magnetic flux density can be detected as an analogue signal by a magnetic detection element 2. The change in the magnetic flux density is generated from the presence of the adhesion parts and non-adhesion parts of the substance due to the intermittent adhesion thereof and, when the rotary body 8 is rotated, the strength of line of magnetic force moves and, by using the element 2, the pulses corresponding to the number of rotations of a motor can be detected.

The control part 4 turns off the light emitting diode 19 of the short-circuit channel of a dimming control signal generation part 16 of a signal terminal unit 3 when the short-circuit signal is inputted. Thus the output is stopped and the output from the dimming control signal output means 17 of the corresponding channel is stopped. Simultaneously, a light emitting diode 9 corresponding to the short-circuit channel is lighted to the address display part 9 of the signal terminal equipment 3 having the short-circuit channel.
