Title: Waterproof type video tape recorder
Inventor: KAMAYA NAOKI
IPC: G11B33/02
Filed: 1985-11-11
Abstract: PURPOSE:To make it impossible to operate a cassette take-out button in a state that a buckle is tightened by providing the buckle which makes stick closely the cover of a cassette holder to a VTR main body, and providing the cassette take-out button at a main body part covered with the buckle. CONSTITUTION:Since a push type cassette take-out button 10 is provided at the main body part covered with a buckle 1, the buckle 1 should be come off when a cassette is taken out. However, at such a time, a cassette control lock is set at the cassette holder, and a cover 7 is stuck closely on the main body. At such a time, by pressing the cassette take-out button 10, a tape hung at a drum or a tape guide is unthreaded and is contained within the cassette, and after that, the cassette control lock is released with the force of a spring, and the cover 7 of the cassette holder is opened, enabling the cassette to be taken out. Thereby, it is evaded that the VTR is operated to a perform a series of operation from an unthreading to a threading and the consecutive recording part of the tape is dislocated and noise is generated even when the cassette take-out button is erroneously operated.

Title: Brushless motor
Inventor: YAMAMURO KIYOSHI
IPC: H02K5/22
Filed: 1992-09-22
Abstract: PURPOSE:To use one and the same magnet for rotation torque, for a frequency generator and for a pulse generator and to reduce the number of components and eventually to reduce the cost by magnetizing a projecting section of a disc-like magnet axially and by obtaining a signal of rotation torque and the frequency generator with a magnetic field of a disc section and by obtaining a location signal of a rotor with a magnetic field of the projecting section. CONSTITUTION:In a drum motor, a magnetic circuit is constructed between a case 8 and a disc section 9a of a disc-like magnet 9 having a projecting section and an iron substrate 14 and power is applied to a coil 11 to rotate a rotor 10. At the same time, the magnetic field generated works on a pattern for a generator on the surface of the iron substrate 14 and induces A.C. voltage. Since this A.C. voltage is determined by the number of magnetic poles of the disc section 9a of the magnet 9 and a pitch angle of the pattern for a generator, this A.C. voltage is used as an electric signal proportional to the speed of rotation of a drum. A magnetic field due to the projecting section 9b of the magnet 9 is magnetized so as to have a magnetic pole boundary 9c and a magnetism detecting element 12 is installed on the iron substrate 14 and is used as an electric signal for detecting the location of the rotor 10.
