Title: Rotation control circuit for rotating magnetic medium recorder and reproducer
Inventor: MIZUNO YOSHIO
IPC: G11B19/28
Filed: 1981-02-10
Abstract: PURPOSE:To achieve rotation control with one system of simple control system, by controlling the rotation of a rotating body so as to synchronize a detection signal obtained with the rotation of a rotating magnetic substance with a vertical synchronizing signal of a video signal in phase. CONSTITUTION:A tone wheel pulse in frequency 60Hz obtained at a rotation detecting magnetic head 25 from a tone wheel 4 is applied to one input terminal of a magnetic wheel set pulse generating circuit 26. A vertical synchronizing signal is applied to another input terminal of a circuit 26 via a terminal 27, and if both the inputs is not coincident in phase, a magnetic wheel set pulse is applied to 1/2 frequency divider 13. On the other hand, a magnetic wheel pulse in double frequency of the horizontal synchronizing signal is applied to another input of the divider, and a phase error output of both the inputs is applied to a sampling pulse generating circuit 15. Thus, a sampling pulse is generated from a circuit 15 and applied to a sample gate circuit 16. The circuit 16 controls a DC motor 2 so that synchronism can be taken with the horizontal synchronizing signal applied from a terminal 19.

Title: Binarizing method for analog signal
Inventor: UNE ATSUNOBU
IPC: H03M1/10
Filed: 1989-01-27
Abstract: PURPOSE:To binarize an analog signal whose amplitude, interval of period and offset component are changed without generating an error by using a value being a division of a difference between a maximum value and a minimum value at a just preceding period of the analog signal to be binarized as a reference value. CONSTITUTION:A maximum value eP and a minimum value eB of an analog signal Sa for each period are latched, the minimum value eB is subtracted from the maximum value eP at a subtracter 4, the result arisen from the subtraction is voltage-divided normally into 1/2 by a voltage divider 5, the resulting value is added to the minimum value eB by an adder 6 and a reference voltage eM is obtained. Thus, even when the amplitude, interval (l) of period and offset component of the analog signal Sa are changed, the conversion to a binarized signal Sd is accurately attained.

Title: Electromagnetic attracting device
Inventor: NEGISHI RIYUUICHI
IPC: H01F7/08
Filed: 1982-02-12
Abstract: PURPOSE:To decrease impact sound and impact force at attracting state and lengthen the life of attracting mechanism, by a method wherein plural coils are driven at the timing difference and one movable piece is driven. CONSTITUTION:A switch 14 of an electromagnetic attracting member 10 having a short core 12 is turned on thereby a movable piece 11 is attracted. Then the movable piece 11 is moved to the position of dotted line and stopped by impinging on a core 22 of an electromagnetic attracting member 20. Since the holding attracting member is not energized then and the electromagnetic attraction does not act between the movable piece 11 and the core 22, the force acting on the movable piece does not rise abruptly and therefore the impact sound is relatively small. And then a switch 24 of the electromagnetic attracting member 20 is turned on thereby the core 22 is energized and the movable piece 11 is attracted. Next, the switch 14 is turned off and the switch 24 remains on and conducting state of a coil 23 is continued thereby the holding attraction is maintained without impinging of the movable piece 11.

Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a light wavelength multiplexer/demultiplexer which has a wide passing range and is reduced in loss by making the slab radius of an output-side slab waveguide less than that of an input-side slab waveguide and providing a multimode waveguide between an input waveguide and input-side slab waveguide. SOLUTION: The radius Ro of curvature of the output-side slab waveguide 7 is smaller than that of the input-side slab waveguide Ri and the multimode waveguide such as an input-side tapered waveguide 4 and a parabolic waveguide 5 is provided between each input-side waveguide 2 and the input-side slab waveguide 3. When signal light is propagated to the input-side slab waveguide 3, its electric field distribution becomes a nearly rectangular distribution. Since the radius Ro of the curvature is smaller than the radius Ri of curvature, the electric field distribution right before an output waveguide 8 becomes a distribution which is reduced in an (x) direction. Therefore, wavelength characteristics whose graph is nearly rectangular while representing the wavelength on its lateral axis and the loss on the longitudinal axis are maintained and further the loss is reduced.

Abstract: PURPOSE:To realize easily broad band and high S/N for a reproducing amplifying system by applying an output of an erase/bias oscillator to a DC voltage generator via a rotary transformer and activating a signal processing circuit by the DC voltage generator. CONSTITUTION:A DC power supply for the supply of power is obtained by amplifying an output of the erase/bias oscillator 15 at an amplifier 25, feeding the amplified result to a rotary cylinder side through a channel 21 of the rotary transformer 18, making the DC voltage generator 24 at the rotary cylinder side receive it and rectifying and smoothing the received output.

Moreover, in constituting the system that a recording/reproducing signal, a control signal and an output of the erase/bias oscillation for power supply are transmitted by the rotary transformer 18, since the number of the rotary heads is made identical to the transmission channel number of the amplifying and rotary transformers, the miniaturization of the rotary transformer is realized.
