Title: Tape player device
Inventor: JIERARUDO DABURIYU TAAPURII JI
IPC: G11B15/44
Filed: 1993-10-18
Abstract: PURPOSE: To provide an inexpensive device for preventing tape supply failure by integrating a circuit for detecting the operational state of a tape in a tape player, and programming algorithm. CONSTITUTION: A device for preventing the supply of an improper tape 26 in a cassette tape player 20 detects the supplied state of the normal tape 26 or the tape 26 running off a correct path by using a pulse width measured from the output signal of a take-up reel 28. The pulse width of the output signal is compared with a prescribed pulse width and range related with a normal tape operation. When the pulse width of the output signal shows the supplied state of the tape running off the correct path beyond the prescribed range, the tape player 20 stops or reverses the rotation of the take-up reel 28.

Title: Magnetic coupling type rotating introduction machine for vacuum equipment
Inventor: SATO FUMIHIKO
IPC: H02K49/10
Filed: 1985-11-19
Abstract: PURPOSE:To make it possible to introduce a large transfer torque to the vacuum vessel by providing a permanent magnet different in polarity from that of the driving wheel on the atmospheric side facing the permanent magnet of the driving wheel on the atmospheric side on the circumferential surface of the coupled driving wheel on the vacuum vessel side. CONSTITUTION:On the surface of a coupled driving wheel 7 on the vacuum vessel side multiple permanent magnets 15 are provided in a projected condition from the surface thereof facing to each permanent magnet 13 of a driving wheel 12 on the atmospheric side. These permanent magnets 15 are arranged so that the next magnet may be of a different polarity. Each permanent magnet 15 is also arranged so that it may be of a reversed polarity against the polarity of the opposed permanent magnet 13 of the driving 12. Consequently, as the driving wheel 12 and the coupled driving wheel 7 are strongly magnetically combined by the attracting force of each opposing permanent magnets 13 and 15, a sufficient powerful transfer torque can be obtained even if the permanent magnets 13 and 15 are not large-sized.

IPC: H02K23/00
Filed: 1993-10-18
Abstract: PURPOSE:To provide a two-layered brush with less spark, even for a short time, when the brush is abraded, by forming a carbon- or electrographite-based layer on the commutator side and a resin-based layer on the opposite side of an abrasion boundary part at a head of the brush body. CONSTITUTION:In a carbon brush 1, a carbon- or electrographite-based brush 1 on the commutator side is abraded gradually as the brush l is used, and then a resin-based brush 12 is abraded from an abrasion boundary part. In abrasion, further, a lead 2 is exposed, and a spark is caused between the brush 1 and the commutator. The resin-based brush part 12 is broken partly at a high temperature caused by the spark. When the resin-based brush 12 is damaged partly, the continuity between the commutator and the lead 2 is broken to stop the motor. In this way, a spark is generated for a short time and the damage of roughness is prevented on the face of the commutator, and the motor can be used again adequately after another brush is inserted therein.
