IPC: H02K37/04
Filed: 1990-10-31
Abstract: PURPOSE:To improve a motor torque by a method wherein magnets are arranged on respective end surfaces of a first and a second rotor cores while the the magnets are magnetized so as to be opposed to the polarity of the magnet pinched between two sets of rotor cores. CONSTITUTION:A first magnet 13 and a second magnet 14 have the same polarity while pinching a first rotor core 11 while the first magnet 13 and a third magnet 15 have the same polarity while pinching a second rotor core 12. The second magnet 14 and the third magnet 15 generate main flux while operating in conjunction with the first magnet 13. On the other hand, the torque T of a stepping motor is shown by a formula. Accordingly, the second magnet 14 and the third magnet 15 increase the flux (PHIg whereby the torque of the motor is increased.

Title: Injection needle disposer
Inventor: WATANABE TADAO
IPC: A61M5/32
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To easily and surely dispose of used injection needles by forming each broadening elastic electrode for pressure contact with an injection needle into a predetermined slidable length, providing a V-shaped electrode immediately below it, and forming a notch in the portion of the elastic electrode to which the injection needle does not abut. SOLUTION: Elastic electrodes 1, 1', formed to open apart so that an injection needle is pressed into contact therewith, are each formed into a slidable length, about 20mm or more. The elastic electrodes 1, 1' are each about 50mm in length and are arranged in the form of a fan with an open angle of about 80 degrees, so that they hold the injection needle at their tangent 2 as the injection needle is pressed into contact with them. A V-shaped electrode 5 formed to have an open angle of about 90 degrees and a length of about 60mm is installed immediately below the tangent 2 to constitute an electrode part. Notches 17 are formed in the portions of the elastic electrodes 1, 1' to which the injection needle does not about. Therefore, the resistance of contact between the injection needle and the V-shaped electrode 5 can be varied.

Title: Focus detecting device
Inventor: ISHIDA TOKUJI
IPC: G02B7/34
Filed: 1985-12-25
Abstract: PURPOSE:To improve the follow-up property to an object, by limiting a shift area in case of an operation of the next time, based on a shift position for giving the best correlation which has been derived by an operation of this time. CONSTITUTION:Based on the maximum correlation position which has been derived in the previous time, the maximum shift position lmax and the minimum shift position lmin of a parameter (l) for determining a reference position of a reference part R are limited. That is, when the maximum correlation has been derived in the second block in the previous time, the second block is used this time, too, but in that case, in case of the rear focus in the previous time, the maximum shift position is set as the maximum correlation position of the previous time, and the minimum shift position is set as a position of the front focus by one pitch portion from the focused position. When the maximum correlation has been derived in the first block in the previous time (the rear focus), the second block is used first this time, too, the maximum shift position is set as a limit of the rear focus side of the second block, and the minimum shift position is set as a position of the front focus by one pitch from the focused position. In this state, if a focus cannot be detected, it is detected by the first block, and if its detection is still impossible, it is detected by the third block. Since the shift range become narrow gradually, the operation speed can be further shortened.

Abstract: PURPOSE:To reliably prevent no-load oscillation of a magnetron for a long time without being thermally influenced by an oven, by a method wherein photosensors are mounted to an oven frame body positioned in a level slightly higher than that of a turn table and on a diameter line passing the axis of the turn table. CONSTITUTION:In a microwave oven, photo-sensors 9 are mounted to both side walls 3c of an oven frame body 3 positioned in a level slightly higher than that of a turn table 8 and on a diameter line passing the axis of the turn table 8. when a substance W to be cooked is placed on the turn table 8 and an openable door 10 is closed to depress a cooking button, light from an emission part 9a of the photo-sensor 9 is shut off by the substance W to be cooked and not collected by a collecting part 9b. In this state, a magnetron 7 is started to oscillate toward an oven 2, and the turn table 8 is rotated. When the cooking button is depressed without placing the substance W to be cooked, light from the emission part 9a is collected by the collecting part 9b, no energization to the magnetron 7 is effected, and no-load oscillation is prevented from occurring.
