Patent JP-H10290593-A (JP)
Title: Drive circuit for sensorless brushless motor
Inventor: KONDO SHUNICHI
IPC: H02P6/18
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To suppress rotational fluctuation of a motor by driving the motor according to a commutation switching signal from a commutation switching circuit thereby eliminating a terminal voltage correction circuit and detecting a voltage induced in the motor accurately. SOLUTION: A buffer circuit 200 supplies a driving current for a motor 10 according to a commutation switching signal from a commutation switching circuit 650. A neutral feedback amplifier 900 detects the neutral potential of the terminal voltage of the motor and compares the neutral potential with a reference potential. When the neutral potential is higher than the reference potential, a first output is fed to the butter circuit 200 otherwise a second output is fed thereto. Since the neutral potential of the motor 10 is invariant, a terminal voltage correction circuit is eliminated and the rotational position can be detected accurately using a voltage induced in the motor 10 and rotational fluctuation thereof can be suppressed.

Title: Welding method with broad electrode
Inventor: WAKAMOTO IKUO
IPC: B23K9/04
Filed: 1984-05-15
Abstract: PURPOSE:To prevent a peeling crack by applying magnetic oscillation to a molten metal by an AC excitation coil to weld a cladding metal and base metal and forming the cladding metal so as to have the same groove depth as the sheet thickness or smaller groove depth than said thickness. CONSTITUTION:A broad electrode 23 is fed by feed rollers 24 to a steel sheet 21 which is a base metal. A ferromagnetic material 27 and the excitation coil 29 are disposed around the end of the electrode 23. The molten pool of a molten metal 35 is made between the steel sheet 21 and the electrode 23 when DC welding current flows to the electrode 23. The molten metal 35 moves laterally and generates the excited flow on account of the alternating field when 1-20Hz AC magnetizing current is passed to the coil 29 in this stage. The finer crystal grains of the molten metal 35 are thus formed and the density of the grain boundary to be precipitated in the stage of a heat treatment is extremely decreased. The peeling crack of the weld metal is prevented by such decrease coupled with the formation of the cladding sheet to the small groove depth.

Title: Method for fabricating terminal part of resin barlike element
Inventor: SATO KAZUHIRO
IPC: B29C53/30
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To enable satisfactory heat-fabricating of the innermost region of a resin barlike element by ultrasonic vibration by setting a distance between the end face of the resin barlike element and a fixing means under specified conditions. SOLUTION: A vibrator 4 is brought into contact with the upper terminal face of a resin tube 20 fixed to a chuck 12, so that an ultrasonic vibration is imparted to the resin tube 20 in a lightly pressurized state. The part coming into contact with a split cavity part on the upper face of the chuck 12, of the resin tube 20 is locally heated. A top force 8 is pushed down until the top force 8 is connected to the upper face of the chuck 12 immediately after the resin tube 20 is heated, and the resin tube 20 is deformed by a force to be applied to the vibrator 4 through heating the part to be molded. In this case, a space between the upper end face of the chuck 12 and the upper and face of the resin tube 20 is set between +30% and -30% of a length equivalent to 1/4 of a wavelength sought by the velocity of the vibrating ultrasonic wave propagating through the resin barlike element 20.

Title: Data processing circuit
Inventor: YOSHIMURA JUNICHI
IPC: H04L69/40
Filed: 1987-04-20
Abstract: PURPOSE:To reduce the fetching impossible time of an alarm data, by fetching the alarm data inputted immediately after the initialization, to an input/output part. CONSTITUTION:A data processing circuit 1 is provided with a CPU 11 and an input/output part 13, and an input/output control circuit 3 inhibits input and output of a data to and from the input/output part 13 at the time of turning on a power source, and sends out a control signal for releasing inhibition of the output, by an input/output inhibition release instruction sent out of the CPU 11. Subsequently, a part for sending out the input/output inhibition release instruction is inserted into the next of an initialized part in a program, therefore, when this instruction is inputted to the input/output control circuit 3, the input/ output inhibition of the data to and from the input/output part 13 can be released by an output from this circuit 3. In such a way, the input/output inhibition release is executed in a short time after the initialization is ended, therefore, it does not occur that the input/output part 13 cannot fetch the data inputted immediately after the initialization is ended.

Title: Ion flow control type recording head
Inventor: SATO HIROAKI
IPC: B41J2/415
Filed: 1985-05-10
Abstract: PURPOSE:To control the flow of ions at a low voltage, by arranging the recording electrode for control so that the electric field for control of the flow of ions acts almost perpendicular to the traveling direction of ion flow. CONSTITUTION:Because an electric field is not generated in a slit 8 when a recording electrode 7, too, is earthed, an ion reaches the upside of recording material 5. On the other hand, when voltage is applied to the recording electrode 7 from the power source 13 for control of ion flow, the electric field is generated perpendicular to the ion flow in the slit 8. Therefore, the ion is bended to the another wall side of slit 8, that is, to the one part side of the bottom of the casing 4, being neutralized by the generation of the exchange of charge there and does not reach the upside of recording material 5. Thus, the ion flow can be controlled by generating the electric field so as to act not parallel to, but perpendicular to the ion flow. Therefore, without requiring a high voltage like 300-500V as a controlled voltage as conventional, the ion flow can be controlled even at 30V of about one tenth thereof.

Title: Slow tracking device
Inventor: MINAMI YOJIRO
IPC: H04N5/783
Filed: 1987-04-20
Abstract: PURPOSE:To perform slow reproduction satisfactorily, by controlling the forming timing of the next braking pulse only when a deviation quantity obtained by overall decision exceeds the range of decision dead zone according to a decided deviation direction. CONSTITUTION:In a still reproduction period at the time of performing the slow reproduction, the deviation direction of the tracking of each one field is decided based on the plural number of times of level detection at the first half and the latter half of each one field, and also, the deviation direction and the deviation quantity of the tracking in the still reproduction period are decided by consolidating the decided result of each one field. And also, only when the deviation quantity on which the overall decision is applied exceeds the range of the decision dead zone set in advance, the forming timing of the next braking pulse is controlled according to an overall-decided deviation direction. In such a way, it is possible to perform the slow reproduction satisfactorily.
