Title: Magnet catcher
Inventor: MIMURA TATSUHIKO
IPC: E05C19/02
Filed: 1995-05-10
Abstract: PURPOSE: To miniaturize a magnet catcher as a whole and improve its assembling property by fixing a yoke to a slider, and continuously reducing the contact area of the yoke to a magnet when the slider is moved from the storage position to the protrusion position. CONSTITUTION: Each time a slider 12 is pushed to the release position, the slider 12 is displaced to the storage position in a casing 1 and the protrusion position forward in turn. A magnet 15 is arranged between a pair of yokes 14 fixed to the slider 12, and the yokes 14 are moved to the protrusion position together with the slider 12. The movement of the magnet 15 relative to the casing 11 is regulated by a magnet holder 16, and it is moved to the demagnetization position at the rear. The contact area of the magnet 15 to the yokes 14 is decreased as the slider 12 is moved to the protrusion position side, and the attracting force of the yokes 14 is continuously decreased. The yokes 14 are moved to the storage position together with the slider 12, the magnet 15 is moved to the magnetization position between the yokes 14, and the attracting force of the yokes 14 is increased.

Title: Installed-in-ceiling type air conditioner
Inventor: KINOSHITA KANJIRO
IPC: F24F1/00
Filed: 1986-05-15
Abstract: PURPOSE:To prevent blown-off air flows from being lifted, by connecting by a duct a room-side unit and a blow-off unit which are installed in the ceiling, and providing the blow-off unit with a centripetal-type fan. CONSTITUTION:Air sucked from a room 4 by a centrifugal-type fan 12 of a room-side unit 15 is subjected to heat exchange by a room-side heat exchanger 13, and is then fed to blow-off units 31 through ducts 34. In the blow-off unit 31, rotation of an impeller 49 of a centripetal-type fan 50 generates a centripetal swirl directed skewly inward relative to the axial direction of the fan 50, and the centripetal property of the air flow is augmented by a fan guide 46. Immediately after air is blown off from the unit 31, a centripetal force is stronger than a centrifugal force, so that air is blown off in the form of a jet with some contraction. Therefore, in a higher region H near a ceiling plate 8, the air flow is supplied downward without diffusing. In a lower region L, the centrifugal force and the diffusing property overcome the centripetal property of the air flow, whereby conditioned air is diffused. Accordingly, an air-conditioned region is lowered, and the air flows (a), (b) can be prevented from being lifted.

Filed: 1994-05-26
Abstract: PURPOSE:To control the thickness of sheet accurately without deteriorating the appearance by regulating the rotational speed of a group of cooing rolls and a take-up roll in extrusion molding. CONSTITUTION:A sheet 1 is fed out from a cooling roll group 2 to a section 4 for measuring the thickness and then the sheet 1 is taken up by a take-up roll 3.

A control section 6 controls current and voltage being fed to the driving sections for the cooling roll group 2 and the take-up roll 3 based on a preset value thus increasing or decreasing the rotational speed.
