Title: Brushless motor and manufacture of rotor parts thereof
Inventor: SUZUKI HITOSHI
IPC: H02K29/00
Filed: 1988-11-18
Abstract: PURPOSE:To suppress torque ripple by making a V-cut groove opening toward the inner circumferential end in a rotor yoke to be adhered to a rotor magnet while facing with the border of the magnetic pole of the rotor magnet. CONSTITUTION:A rotor part 21 comprises a rotor magnet 22 and a rotor yoke 23. The rotor magnet 22 has ring shape and alternately magnetized with S and N poles.

Patent JP-H03153284-A (JP)
Title: Printer
Inventor: HORINOUCHI SHOGO
IPC: B41J2/325
Filed: 1989-11-10
Abstract: PURPOSE:To miniaturize a device and to reduce the cost thereof by transferring an ink attached to a platen to a printing paper and heating a part passing through the transfer part of the platen to a temperature higher than a Curie point. CONSTITUTION:When a current is made to flow by a signal generation circuit 7 according to the information recorded on an optional electrode 8, it is returned to the circuit 7 through the electrode 8, a (p) point, a water-repellent thin film 4, a magnetic recording layer 3 and the core body of the platen 2. At this time, since the film 4 and the layer 3 have an electric resistance, an area 3s generates heat by the current. Since coercive-force is eliminated when the area 3s of the layer 3 is heated to the temperature equal to or exceeding the Curie point of a magnetic material by the generated heat, the layer 3 is easily magnetized in the direction of a magnetic field 6a by the magnetic field 6a produced by a permanent magnet 6 and the information is written. Thus, since a line magnetic head and a demagnetizing head need not be used, the device can be inexpensively constituted.

Title: Beam-current measuring apparatus
Inventor: KUMAZAKI HIRONORI
IPC: G01T1/29
Filed: 1991-11-11
Abstract: PURPOSE:To decrease the deterioration of the frequency response of a beam current and errors measurement caused by a signal cable. CONSTITUTION:A beam current is converted into the output voltage within the specified voltage range. The range condition signal indicating the amplification factor in conversion and the output voltage are outputted with a beam- current amplifier unit 5. An irradiation-amount computing means obtains the irradiation amount of an ion beam 1 by using the output voltage and the range condition signal. The above described beam-current amplifier unit 15 and a Faraday device 12 are arranged together in a vacuum chamber. The output voltage and the range condition signal are outputted into the irradiation-amount computing means at the outside of the vacuum chamber through a signal cable 29. Since the beam-current amplifier unit 15 is located at the front stage of the signal cable 29, the effect of the capacitance of the signal cable 29 is not received when the beam current is converted into the output voltage. The output voltage, which is obtained by amplifying and converting the beam current, is hardly affected by the noise of the signal cable 29.
