Filed: 1978-10-13
Abstract: PURPOSE:To make it unnecessary to adding a circuit corresponding to a compensating circuit in a multiplier circuit, etc., in the system which is operated by clocks from a clock supply unit provided commonly for plural digital devices. CONSTITUTION:Digital devices 1 and 2 receive distribution of clocks from reference clock source 3, and clocks are multiplied by 11 and 21 and form internal clocks 13 and 23 and are supplied to information transmission/receiving circuits 14 and 24 and circuits 16 and 26 taking interface to them.

Patent JP-H0419674-A (JP)
Title: Contact electrostatic charger
Inventor: KOGA SHINJI
IPC: G03G15/02
Filed: 1990-05-14
Abstract: PURPOSE:To attain miniaturization and simplification by allowing an electrostatic charging means to contact to the surface of a photosensitive body in response to the displacement of an action means which displaces as a magnet displaces by electromagnetic inducting action and separating it from the surface of the photosensitive body in response to the restoration of the action means. CONSTITUTION:By interlocking with the action of the photosensitive body 1, a conductive planar substance 4 moves and the electromagnetic inducting action is generated between the substance 4 and the magnet 6 arranged so as to interpose the outer periphery of the substance 4, then an induced current flows in the substance 4 and the magnet 6 displaces in the rotating direction of the planar substance by resisting a restoring means 7. The action means 5 is displaced with the displacement of the magnet 6, and the electrostatic charging means 2 is allowed to contact to the surface of the photosensitive body 1. Since the electromagnetic inducting action is eliminated when the photosensitive body stops and the planar substance also stops, the magnet and the action means 5 are restored to an initial position by the means 7 and the means 2 is separated from the surface of the photosensitive body. Thus, a complicated mechanism for contact and separation is not necessitated and the miniaturization and the simplification are attained.

Title: Method for packaging aluminum chloride anhydride
Inventor: SASAGAWA YUKIO
IPC: B65D85/84
Filed: 1994-05-17
Abstract: PURPOSE:To prevent the production of corrosive gases in a packaging container and thus suppress the corrosion of the container by a method wherein aluminum chloride anhydride is packed with a gas-permeable packaging material independently and calcium oxide, together with the aluminum chloride anhydride, is packed in the same container in an amount of a specific weight percentage based on the aluminum chloride anhydride. CONSTITUTION:Calcium oxide is used preferably in a powdery or granular form with an average size of at most 5mm in diameter and in an amount of 0.01-10wt.% based on aluminum chloride anhydride. The calcium oxide, together with a separately packed aluminum chloride anhydride, is packed in the same container to avoid the mixing with the aluminum chloride anhydride. As the packaging material for packing the calcium oxide, the material resisting to corrosive gases, e.g. synthetic fiber, inorganic fiber and paper having resistance to chemicals and acid, is preferably used. In this way the water mixed in the packaging container reacts with the calcium oxide to form calcium hydroxide, whereby the water is fixed and the generation of corrosive gases is prevented.
