Title: Magnetic disk device
Inventor: SUMITA TOSHIYUKI
IPC: G11B20/18
Filed: 1983-07-19
Abstract: PURPOSE:To reduce less a defective area to prevent the reduction of recording capacity due to a defect of a recording medium by absorbing a constant error produced at a part of a recording area into a gap G to obtain a nondefective sector and at the same time reducing the DATA part of a data field if the absorption of the error is impossible. CONSTITUTION:An ECC error is detected after both the DATA and ECC parts are read, and an ECC correcting circuit 7 is operated to know an error location. Here it is known that the error location exists only at the rear part of the dapa field. Thus it is checked whether the physical positions of both ID and data fields can be altered or not. When this alteration is possible, the physical positions of both fields are altered by the next rotation and recorded. This format to be altered can be fixed or varied in response to the error location. If the alteration is impossible, the relevant sector is decided defective and processed. Otherwise the DATA part is reduced to secure the application of said sector.

Title: Method for measuring thickness of plated film and depth of etched groove during course of wet process
Inventor: SHIYOUNO TOMOTAKA
IPC: C23F1/00
Filed: 1992-05-22
Abstract: PURPOSE:To accurately measure the thickness of a plated film during the course of a plating process by detecting a potential or current change by irradiating a plated member held under a constant-current or constant-voltage condition in an aqueous solution with a laser beam. CONSTITUTION:A member 2 (cathode) to be plated held under a constant-current condition with a galvanostat 11 in a plating liquid is irradiated with a laser beam 1 and the periodical potential variation caused by the irradiation of the laser beam 1 is detected separately from a steady-state potential by means of a lock-in amplifier 15 which inputs a modulating signal sent to a laser oscillator 12 as a reference input. Since the potential variation varies depending upon the thickness of a plated film, the thickness of the film plated on the member 2 can be easily, accurately, and quickly measured during the course of a plating process by utilizing the above-mentioned relation. The depth of an etched groove can also be measured in the same way.

Title: Commutator motor
Inventor: NISHIMURA TAKESHI
IPC: H02K13/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a long life and effective commutator motor by suppressing sparks by a motor blower. SOLUTION: Each commutator piece 82 forming a commutator 33 is formed by laminating in parallel a plurality of materials 32a, 32b, having different electric resistance values for a rotating axis 38. A material 32 having a larger electric resistance value is used in a side, where after the commutator piece 32 has made contact with a brush 37, it is isolated from the brush 37. As a result, a resistance gradually becomes smaller towards the leading direction of rotation of the armature. With such a structure, since the electrical resistance value on a side where the commutator piece 32 is separated from the brush 37 is larger, a flow of induced current is made difficult, and thereby suppressing sparks.

Abstract: PROBLEM TO BE SOLVED: To report call termination to a user even when receiver off-hook is generated by calling the user regardless of the state of a subscriber telephone set interface means at the time of detecting calling. SOLUTION: In the case that the receiver of a subscriber telephone set 107 is off-hooked, the off-hook state of the subscriber telephone system 107 is detected in a 2-wire monitoring part, and since the calling device of the normal subscriber telephone set 107 for reporting the information of the receiver off- hook to a CPU is driven by an AC, a DC loop is formed between the subscriber telephone set 107 and a subscriber terminal equipment 105 in the off-hook state where the receiver is off-hooked and thus, call termination detection (calling device ringing) becomes impossible.  Then, the CPU judges the receiver off-hook information by receiving a receiver off-hook report, controls a calling communication switching part and sends out instruction signals to a second calling device so as to perform singing and singing is performed by receiving the instruction signals by the calling device.
