Title: Disk tray device
Inventor: SAKURADA MASATAKA
IPC: G11B23/023
Filed: 1991-03-25
Abstract: PURPOSE:To comply with the compression of a tray main-body due to a temperature change and to prevent the tray main-body from being damaged by an external force by a method wherein the tray main-body is attached to a tray support frame body via an elastic member. CONSTITUTION:Two shaft holes 3 are made in a train main-body 1; support rods 4 are inserted and passed so as to be capable of being slid and moved; both ends of the support rods 4 are fixed to side plates at a tray support frame body 2. Coil springs 5 are laid between both end faces at the tray main-body 1 and both side plates at the tray support frame body 2. Disks are housed in individual grooves at a tray; they are taken out from the individual grooves by utilizing a prescribed detection part. As a result, they are not fixed directly to their support body even when they are compressed thermally, and the displacement of the individual grooves is reduced against the deformation of the tray. The support body itself is not damaged when it is expanded at a high temperature, and it is possible to prevent it from being damaged as compared with the coupling and bonding operation of an elastic body on only one side as in conventional cases.

Title: Converting circuit
Inventor: SAGA RIYOUHEI
IPC: H03M1/68
Filed: 1983-04-08
Abstract: PURPOSE:To eliminate an error during converting operation by detecting currents of the 1st and the 2nd A/D or D/A converting circuits in operation, controlling the current of one converting circuit on the basis of the difference current of the two, and equalizing the current amplification factors of both converting circuits to each other. CONSTITUTION:When the hFE of a TRQA of a compensating circuit is equal to factors hFE of TRs Q41-Q46, and Q33 and Q34, the sum SIGMAIO of output currents is determined by collector currents I of TRs Q1, Q1', and Q2', the collector current IZ of the TRQA, and factors hFE. In this case, when IZ=2I, an error of hFE is reduced, but this is not perfect compensation. The collector current lY of a TRQ21 of a compensating circuit 12 is a half as large as emitter currents I of TRs Q2 and Q2' and the collector current of the QA. The sum of the current I and the base current of the TRQA determined by the currents I and IY, collector current of a TRQA11, and emitter current of the QA is a reference current in D/A conversion. Therefore, the total of output currents IO is I. Namely, the compensating circuits 11 and 12 eliminate an error between D/A conversion by segment circuits 2-9 and D/A conversion by a ladder network.

Filed: 1989-03-13
Abstract: PURPOSE:To continuously check the characteristics of a long band-shaped magnetic substance in its lengthwise direction by setting plural sensor coils in the lengthwise direction of a bar exciting coil. CONSTITUTION:A major axis XE of an exciting coil E is turned in the width direction of a band-shaped magnetic substance M, and the sensor coils D1 - D5 are dispersely set in the direction of the axis XE. Then an alternating current is supplied to the coil E for generation of an AC magnetic field.
