Title: Frequency converter
Inventor: SEKINO YOSHIHIRO
IPC: H02M7/493
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To restrain a cost increase and attain higher reliability, by using at least one converter and at least one inverter of three or more conversion devices, and at least one inverter/converter selectable to either of them. SOLUTION: Normally, selective switches SB1 , SA2 are closed respectively, and SA1 and SB2 are opened respectively. A forward converter 2 converts AC power of an AC power source 1 into DC power to be fed to an inverter 3 and charges a battery 6. The inverter 3 is fed to a load 5, and an inverter/ converter 4 is on standby in an inverse conversion mode. If the AC power source 1 fails, the converter 2 stops, and the inverter 3 converts DC power generated by discharging the battery 6 into AC power to feed it to the load 5. If the inverter 3 fails, the selective switch SB1 is opened, and the SB2 is closed to feed t the load 5 from the inverter/converter 4 which has been on standby.

Title: Position detector
Inventor: WARISAYA KANJI
IPC: G11B21/08
Filed: 1987-08-28
Abstract: PURPOSE:To enable the accurate and highly reliable detection of the position of a head, by providing a variable-capacitance capacitor prepared by providing electrode plates on a head-mounting movable element and on the fixed side of the head respectively. CONSTITUTION:The capacity of a variable-capacitance capacitor 11 constructed of electrode plates 4 and 7 is increased and descreated with the movement of an optical head mount 2 on a rail 3. When an output signal of a detecting unit 10 is inputted to a control unit 12, this unit 12 determines the position of an optical head from the amplitude of the capacity of the capacitor 11 and delivers a control signal to an amplifier 5 so as to move the head to a desired position of an optical disk 13. In the case when a sharp change occurs at points C and D during the increase or decrease of the capacity of the capacitor 11, the control unit 12 judges that the mount 2 is located at an abnormal position and conducts an operation for abnormality, i.e. an operation of generating a signal for stopping an output of the optical head or a signal for indicating the abnormality thereof, or the like. The independence from a reproduced output signal being secured, accordingly, detection can be executed free from the effect of a change in a reproduced output and the reliability of a position control is improved since the effect of dust and the like is little.

Title: Inspection of product in finish rolling mill for seamless steel pipe
Inventor: NAITO YOSHIKAZU
IPC: B21B38/00
Filed: 1984-10-15
Abstract: PURPOSE:To improve quality assurance by selecting the stands contributing to substantial rolling by interposing an ineffective stand for idle passing between the final stand and the stage before the same and incorporating a size measuring instrument and flaw detector into said ineffective stand. CONSTITUTION:The (i+1)th stand from the top is determined as the final stage An of the stands arrayed as shown in the figure and the i-th stand just before the same is determined as the ineffective stand B for idle passing of a material if it is assumed that the number of the stands necessary of executing the giving rolling schedule is assumed to be i pieces. Then the material has the tendency to receive always tension in the final stand An and the stand An-1 before the same and is substantially free from deviation. Since the detector is installed by incorporating the same into the rolling stand itself, the sure supporting of the detector itself is made possible. The size measurement or flaw detection is thus made possible with the extremely stable accuracy by such supporting coupled with the above-mentioned absence of the deviation of the pipe.
