Title: Brushless motor
Inventor: OISHI YASUO
IPC: H02K29/08
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To make it difficult for a Hall element to be influenced by leakage magnetic flux generated by a drive current flowing in a coil, by forming in a board a cut and raised part which adjoins a magnetic detecting element in such a way as to interrupt leakage magnetic flux from at least one of a coil and a core. SOLUTION: A brushless motor has a shield section 13 formed by cutting and raising a part of a stator yoke 12 made of a magnetic metal plate. And the shield section 13 is formed at a position separated from two salient poles by distances approximately equal, and adjoining a Hall element 9 and the axial directions of a capstan 3. Consequently, it becomes difficult for the Hall element 9 to be influenced by leakage magnetic flux from a coil or salient poles, even when a large current flows at the time of a motor start or a heavy load, and it becomes possible for the Hall element 9 to sense only a magnetic flux change generated by the rotation of a drive ring magnet 7 fixed to the rotor 6.

Title: Microprocessor
Inventor: YAMAKOSHI MASAHIKO
IPC: G06F11/28
Filed: 1985-08-30
Abstract: PURPOSE:To easily monitor or modify an indicating address without affecting the execution of an instruction by providing two indication address circuits, using the one for generating a mask disable interrupting command and the other for monitor. CONSTITUTION:Data '1' is stored only at the indication addresses of the 1st and 2nd indication address memory circuits 10 and 11. An address from a CPU 1 is supplied to the 1st indication address memory circuit 10 through a memory address switching circuit 14. When the read-out data is '1', a signal from a mask disable interruption generator circuit 8 shifts the control of the CPU 1 to a monitor program. When a value at the indicated address is monitored, only the contents in the circuit 11 are read out because the contents in the circuits 10 and 11 are equal. When the indicated address is modified, the contents in the circuit 11 are modified, after which a switching circuit 14 is switched so that the address from the CPU 1 can be supplied to the circuit 11. Accordingly the contents in the circuit 10 are modified.

The signal separator 6 generates the open waveguide of a rectangular section at the input terminal and it becomes the conductive wall of the independent waveguide having two rectangular sections at an output terminal 46. A series of posts 48 in the plane of the septum 42 are provided between the input terminal 44 and the output terminal 46. The posts 48 form a mode transducer between the square input and forked outputs. A separated high-order mode connected to the input/output sections is converted into the diversity signal of a basic mode, which transmits through one output waveguide or both waveguides, so as to supply it.

Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To provide an unlocking device for upper and lower opening and closing door comparatively simple in structure and capable of easily unlocking a lock device from a landing side. SOLUTION: This device is constituted of a handle member 10 made of a round bar and a weight member 11 welded at a rear end of the handle member 10.
