IPC: G11B5/02
Filed: 1984-06-07
Abstract: PURPOSE:To increase a reproducing voltage by providing an adder adding outputs of plural reproducing amplifiers connected respectively to plural windings interlinking with a magnetic circuit in a magnetic head. CONSTITUTION:A reproducing voltage is generated in windings 11, 12 to a reproduced magnetic flux of a magnetic head core, and since the plural windings 11, 12 and the reproducing amplifiers 13, 14 are provided in the same magnetic circuit, then a reproduced output becomes a voltage corresponding to the entire winding number 2N (N is the winding number of each winding). A resonance frequency deciding the operating possible band as a magnetic head depends on the product between the inductance and the stray capacitance of each winding, even when plural winding groups are provided, the resonance frequency is the same as the case with a single winding. As a result, while the reproduced output is increased to a value corresponding to the total winding number 2N, the resonance value is kept to a high value of the each split winding.

Abstract: PURPOSE:To eliminate the stop of a sequence caused by stop to convey a card by inverting a card conveying motor and discharging the card when the length of the led-in card is shorter than a specified length. CONSTITUTION:An interval timer 83 starts operation according to an insertion detecting signal, turns on an opening / closing means 85 at fixed time intervals (t) and monitors the presence and absence of an output from an inverter 86. When the length of the inserted card is shorter than the specified length and the detection output of an insertion sensor is extincted at a time T2, for exam ple, there is the output of the inverter 86 in the case that the opening / closing means 85 is turned on according to the output of the interval timer 83 at a time T3.

A forward rotating signal FWD to a motor 82 is interrupted and simultaneously, the output of the inverter 86 is latched by a latch 87 as a backward rotating signal REV of the motor 82. Then, the motor 82 is driven backward and a conveying mecha nism discharges the card. Thus, after the card is inserted, trouble caused by the stop of the operation sequence is avoided.

Filed: 1989-05-10
Abstract: PURPOSE:To minimize the interruption frequency of transfer of data owing to the refresh actions by making use of the temperature characteristic of a dynamic memory to measure the temperature of the dynamic memory and to change the refresh cycle. CONSTITUTION:A temperature sensor part 2 senses the temperature of a dynamic memory 1 and reports it to a refresh cycle control part 3.

The arbiter 6 inhibits an access control part 5 from using the memory bus and interrupts temporarily the transfer of data. Then the arbiter 6 grants the part 4 to use the memory bus. Thus the part 4 produces the refresh control timing and uses the memory bus via the arbiter 6 to refresh the memory 1. As a result, the interruption frequency owing to the refresh actions can be minimized for transfer of data.
