Title: Belt-driven recording-tape cartridge
Inventor: KURIWADA TAKESHI
IPC: G11B23/087
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To stabilize the touching of a recording tape on a magnetic head without giving any damage to the tape by providing rotating rollers between a drive roller and tape packs. SOLUTION: Rotating rollers 1a and 16b are provided between a drive roller 13 and the tape packs 5a and 5b of tape reels 2 and 3 and a driving belt 6 is put around the rollers 16a and 16b and tap packs 5a and 5b. As a result, the path line of the belt 6 is expanded outward and the contacting length of the belt 6 with the drive roller 13 becomes shorter. Therefore, the variation of the tape tension and driving torque of the path line 5c of a recording tape 5 can be reduced and the data error which is caused by the variation of the touching of the tape 5 on a magnetic head 12 can be eliminated by stabilizing the touching. It is preferable to fix the supporting shafts of the rollers 16a and 16b to a base plate 7.

Title: Constant current source type filter
Inventor: NARITA KENJI
IPC: H04M19/00
Filed: 1980-12-16
Abstract: PURPOSE:To increase an AC load of a telephone set sufficiently and to suppress the variance in low frequencies for a power supply voltage, by using a constant current source device supplying the regulated power supply in DC manner to the power supply circuit of a subscriber circuit. CONSTITUTION:Since a cut-off frequency of a low pass filter 23 is sufficiently lower than the audio frequency, if a bias voltage VF has a voltage change in higher frequency than the cut-off frequency of the low pass filter VF, although an output voltage VREF' of an amplifying circuit A4 changes, the output voltage of the low pass filter 23, i.e., a reference voltage VREF is not changed. Thus, this filter circuit has no voltage regulating action to signals of audio frequency, and an AC impedance viewed from a telephone set SUB is increased. On the other hand, when a bias voltage VF has a stationary error with the change in the power supply voltage, i.e., the output voltage of a DC-DC converter 24, the value of a bias voltage VP is corrected through voltage regulation.

Title: Record player with record cleaner
Inventor: WATANABE MASAYOSHI
IPC: G11B3/58
Filed: 1984-08-27
Abstract: PURPOSE:To remove dust on a record without worrying about a malfunction by rotating a rotary brush so that it rotates its rotary direction and rotary supporting point toward the proceeding direction. CONSTITUTION:When the long direction of the rotary brush 2 is turned to the direction of a turntable shaft 14 at the supporting point 11 in a cleaner case 10, an idler 6 makes contact with the external circumference 13 of the turntable. At this time, the shaft of the idler 6 is so constructed that its radii from the center of the turntable shaft 14 is smaller that from the supporting point 11, i.e. Ra< Rb. The supporting point of the case is placed so that the friction force between the rotary brush and record occurs to press the idler onto the turntable. The shaft center of the idler is set so that it closes to the turntable shaft than the supporting point of the case when the shaft center of the idler makes contact with the turntable. This causes the rotary brush to keep the direction of the turntable by the friction force with the record even if there is no pressing force to the case, so the dust on the record can be removed without any mulfunctions.

Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To protect a semiconductor device against damage due to etching by measuring a faint light produced in a reaction chamber using an amplifying means for light emitted from the chamber. SOLUTION: An object to be etched is loaded on an RF susceptor 42 being set in a reaction chamber 40. A plasma is formed in the reaction chamber 40 in order to etch the object. When the object is being etched using plasma, reaction residue of an etching species in the plasma and the object is produced in the reaction chamber 40. The etching species and reaction residue emit light inherent to respective substances. The light reciprocates between mirrors 44a, 44b and strikes against other etching species or reaction residue in the reaction chamber 40 on the optical path to induce emission of light. When the illuminance of light induced between the mirrors 44a, 44b exceeds a predetermined level, a part of induced light 48 escapes through a partial transmission mirror 44b and detected by a detector 46.
