Title: Superconducting switching element
Inventor: YUZURIHARA HAJIME
IPC: H01L39/22
Filed: 1989-12-19
Abstract: PURPOSE:To obtain a superconducting switching device which is low in power consumption and high in response speed and able to perform a switching operation without using external light rays or a magnetic field by a method wherein a current electrode, applied on a first and a second superconducting thin films, and an electrode which applies a magnetic field vertical to a substrate applied on an antiferromagnetic thin film are provided, and a superconductor and an antiferromagnetic substance are combined together. CONSTITUTION:Current supplying electrodes 5 of a first and a second superconductive thin film, 2A and 2B, are connected to a power supply, and when a current is made to flow between the superconduction thin films 2A and 2B as a switching device is cooled down to a critical temperature or below, a current flows through a proximity effect that a superconducting current flowing through one of the superconducting thin films 2A and 2B flows through a ME film 3 and reaches to the other superconducting film. Then, when a voltage is applied to an electrode 4 of the ME film 3 and an electrical field vertical to the substrate 1 is applied to the ME film 3, a magnetic moment is induced in the film 3 in parallel with the electrical field to turn the film 3 into a ferromagnetic state. By this induced magnetic moment, a superconductive current is turned into a normal conductive current, and in result a resistance is induced to generate a voltage. Therefore, if a voltage signal, which changes from a zero potential to a limited potential before and after an electrical field is applied, is read and employed according to an ON-OFF action, a superconducting device of this design can effectively function as a switching device.

Title: Reproducing apparatus
Inventor: SEDO KAZUHIKO
IPC: G11B21/08
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a reproducing apparatus in which an address to be accessed is detected easily by a simple operation by a method wherein a reference address is designated so as to be step-fed in a fixed step width. SOLUTION: When a step FF key is pressed in a reproducing operation, a system controller takes into, as a reference address TN, an address in a reproducing position at a point of time when the key is pressed. Then, when a fixed step width (a) of 30 seconds is added to the reference address TN, an address to be accessed is computed. When the address to be accessed is computed, an optical head is accessed, and the reproducing operation is started. In addition, when a step REW key is pressed, an address in a reproducing position at a point of time when the key is pressed is taken into as the reference address TN. Then, when the fixed step width (a) of 30 seconds is subtracted from the address TN, the address to be accessed is computed.  In this manner, a position which is estimated to be a part to be heard is designated by a step access operation, and a target place is detected easily by a little fast-forward operation.

Title: Printing head driving control device
Inventor: NAKAMURA MASATOSHI
IPC: B41J2/30
Filed: 1990-11-30
Abstract: PURPOSE:To perform uniform printing by a method wherein a driving time is previously set for each printing wire, and the driving power is kept uniform in response to the variation of driving voltage. CONSTITUTION:A register for driving time initializing 15 sets a driving time in response to the number of printing wires which are driven at the same time, in steps. A driving voltage Vp is applied to the negative input of a comparator CMP1 in a driving power control unit, and to the positive input, a reference voltage Vc is applied. While a driving timing signal T is kept to be output from a flip-flop FF, the voltage V1 of the negative input terminal is kept at a low level, and the output voltage V2 is kept at a high level, and when the voltage V1 reached the voltage Vs of the positive input terminal, it is kept at a low level. The driving current which flows on a driving coil group l1 keeps ascending until the output of the comparator CMP1 becomes a low level, and then, starts decreasing, and when a driving effective voltage V3 becomes a low level, the flow of the current is forcibly stopped. Thus, by making longer the supply time for the driving current, larger the total number of printing wires which are driven at the same time becomes, the driving power is increased.
