Title: Transformer
Inventor: TAKAI MEIJI
IPC: H01F27/36
Filed: 1979-07-12
Abstract: PURPOSE:To enhance the shielding effect, decrease the loss caused by the leaking magnetic flux of the winding, and eliminate the concentration of the electric field at edge portion by placing rectanguler iron plates on a winding supporting surface of a fastening metal member as a magnetic shielding plates, and rounding outer edges thereof. CONSTITUTION:The rectangular iron plates are placed on the winding supporting surface 4b of fastening metal member 4 in a vertical state as magnetic sheilding plates 5. One corner of the rectangular iron plates which are adjacent to the outside edges of transformer windings 2 and 3 is rounded and machined. The edges of the iron plates on the side of the iron core are contacted with the iron core. Since leaking magnetic flux phi from the inner winding 2 and the outer winding 3 passes in parallel with the most wide plane of the rectangular iron plate, eddy currents can be suppressed. Since the iron plates 5 wide and rounded, the concentration of the electric field can be prevented. Furthermore, since the leaking magnetic flux is conducted to the iron core through the shortest path of the magnetic shielding plates, the shielding effect can be enhanced.

Title: Counter device for video tape recorder
Inventor: YAMAYOSHI RYUICHI
IPC: G11B27/19
Filed: 1985-04-25
Abstract: PURPOSE:To count up pilot signals precisely independently of the traveling speed of a tape, to display the traveling distance of the tape and to detect also its traveling direction by adding or subtracting the counted value on the basis of the output of an ATF pilot signal. CONSTITUTION:When reproducing is executed at a normal speed in the positive direction, the supply of pilot signals from BPFs 18-21 to a CPU 22 is successive ly changed in the order of f1 f2 f3 f4 in each scanning period. In this case, the CPU 22 adds the counted value every change of the pilot signals. In case of reproducing at a speed of several times in the reverse direction, the CPU 22 does not count up the initial and final reproducing pilot signals in each scanning period and subtracts the counted value at every change of pilot signals except the initial and final ones. Thus, the pilot signals can be properly counted up in both the forward and reverse directions, so that a precise counted value can be obtained.

Abstract: PURPOSE:To analyze an operation of a system in which a microprocessor is used by storing and displaying a state of a bus of the microprocessor or a process of an execution of an instruction. CONSTITUTION:When a switch 9 is on, and a start signal is applied to a memory controlling circuit 4, as for a storage operation, nothing is stored in a memory 2 unless there is an instruction whose stack is varied or a response of an interruption.
