Title: Magnetic recording device
Inventor: HAYASHI TORU
IPC: G11B20/10
Filed: 1993-11-02
Abstract: PURPOSE:To follow even large fluctuation in the traveling speed of a medium by generating clock signals having an interval which is the product of the interval of the timing signals generated in accordance with the traveling speed of a magnetic recording medium and the recording density/set recording density computed in a computing section. CONSTITUTION:A motor control circuit 21 controls the rotation of the running motor of a magnetic recording medium A such as a magnetic card at a constant speed and an encoder 22 generates timing signals corresponding to the traveling speed. A CPU 23 outputs clock signals having an interval tXn where (t) is the interval of the timing signals and (n) is the recording density/set recording density and a write circuit 24 records data on the medium A using the signals above. A read circuit 25 confirms the reading of the recorded data of the medium A and the CPU 23 judges 1 and 0 by the presence or the adsence of the reading signal within the 60 to 80% window of the tXn interval of the generated clock signal. Thus, even through the recording density varies and the traveling speed of the medium A greatly fluctuates, its function is fulfilled.

Title: Resistor element and manufacture thereof
Inventor: OYAMA HITOSHI
IPC: H01C3/00
Filed: 1990-10-11
Abstract: PURPOSE:To achieve a high-precision resistor by linearly placing ultrathin resistance wires between the electrodes on an insulation substrate to produce the required resistance value. CONSTITUTION:For example, the electrodes 2-1-2-n are formed on a printed circuit board 1 and a 50mumphi Ni80Cr20 wire (specific resistance = 109OMEGA.cm) is used. Such a wire is stretched between two adjacent electrodes by soldering with a slight tension, and, in this manner, the electrodes 2-1 to 2-n are serially connected to form many resistance elements whose resistances are each determined by the distance between adjacent electrode terminals on the printed circuit board. Also, after a large number of electrodes 2 are formed on an alumina circuit board 4 and a resistance wire 3 is used to connect pairs of two opposing electrodes in the same manner as above, it is possible to cut the circuit board 4 and divide it into separate devices. When this device is connected with a slight amount of elasticity using an ultrathin wire which is bendable and easily extended and the resistance value result in the lengthwise direction of the wire is kept within + or -10% of the standard value, it is possible to achieve even greater precision control of the resistance value.

Filed: 1984-12-28
Abstract: PURPOSE:To obtain an information signal reproducing equipment with much convenience by adopting a constitution that the edge of a tape recording medium is detected and whether the edge is the end or the start of the tape is detected as to each region. CONSTITUTION:When the edge is detected, a designated region is changed over and whether the edge is the start or the end is discriminated as to a region designated newly, and when it is the start, reproduction is applied and when the edge is the end, the tape undergoes fast feeding automatically toward the opposite edge to be the start. In case of the fast feeding for example, the region designated cannot be reproduced when it comes to the edge. When the edge is detected, a region designating circuit 24 switches the designated region. The changeover of the designated region is executed between regions where the tape running direction at recording differs. Accordingly a capstan to be used is selected as well and a capstan driving the tape in opposite direction to a capstan used for the reproduction of the designated region so far is activated.
