Title: Subdivision packing device for powdery/granular body
Inventor: DOI KAZUKI
IPC: B65B1/30
Filed: 1990-01-16
Abstract: PURPOSE:To make it possible to subdivision-pack with an even density by a method wherein the title device is constituted in such a manner that when powdery/granular body to be processed is divided, a filling density control device moves away from the division operating position of the powdery/granular body. CONSTITUTION:When a powdery medicine is division-packed, a prepared powdery medicine A is loaded in a hopper 16 to feed the powdery medicine in a subcylinder 42, and the subcylinder 42 is moved to a position which is directly above a measuring cylinder 20, by traversing a moving plate 40. When all the powdery medicine A has been received in the measuring cylinder 20, a filling density control device 50 is moved to a position which is directly above the measuring cylinder 20 by further traversing the moving plate 40. Then, a driving motor 56 is operated, and a supporting frame 51 is lowered, and a pressurizing piston 52 is inserted in a cylinder 21 together with a supporting body 54, and at the same time, a piston 23 is raised, and the filled powdery medicine A is pressurized from both directions, from the top and the bottom. At this time, if the powdery medicine A is pressed by approximately 2 to 3 times larger force of the pressurizing force of the pressurizing piston 52, air which exists between particles of the powdery/granular body is discharged only to the upper direction through gaps, and therefore, subdivision-packing with an even density becomes possible.

Title: Production of hydrogen
Inventor: SUZUKI MASAHIRO
IPC: C01B3/08
Filed: 1981-01-20
Abstract: PURPOSE: Particles of an appropriate metal oxide are embedded on the surface of a Mg powder or foil and they are brought into contact with an aqueous solution of a neutral salt to produce hydrogen continuously at a proper generation rate.  
     CONSTITUTION: Particles of higher than 200 mesh, which are made of at least one selected from Fe, Cr, Mn, Zn, Ni and their oxides are embedded on the surface of Mg powder, foil or particles by a mechanical means such as pressing or friction force. The resultant magnesium material is brought into contact with a neutral aqueous solution of NaCl, KCl or Na 2 SO 4  or sea water to generate hydrogen. This method prohibits the formation of magnesium hydroxide on the magnesium surface and makes it possible to form a large amount of high-purity hydrogen continuously and stably.

Title: Selective calling signal system
Inventor: SAIKI YUKIO
IPC: H04B7/26
Filed: 1981-01-23
Abstract: PURPOSE:To eliminate disturbance due to interference between radio waves sent from a calling station and a called station by giving a difference between the transmission patterns of on-hook signals that the calling and called stations send via a single radio circuit. CONSTITUTION:Even if radio waves including on-hook signals sent from a calling statin and a called station arrive at a base station at the same time, the radio waves never overlap each other for a constant time or longer without fail by making the pattern of radio-wave transmission differnt between the calling and called stations. Therefore, the fault that the on-hook signal is not received by the base station owing to radio-wave interference is solved.

Filed: 1989-01-19
Abstract: PURPOSE:To arrange papers in order securely without losing matching of system functions by providing a controlling means for counting the number of papers placed on a bin and making an arranging means inoperative when the counted value exceeds a predetermined value. CONSTITUTION:At the time of discharging a copy, an upper entry sensor 629 or a lower entry sensor 628 for detecting the discharge of a paper to a bin is first turned ON, and is thereafter turned OFF upon completion of the discharge. The point of the change from the ON state to the OFF state corresponds to the trailing end of the paper. With the timing of the change, a timer in a CPU 600 is started, and the value on the timer is monitored. When it is judged that 300 msec has passed from the start of the timer, the timer is stopped. Simultaneously, if oscillation is possible, an oscillating motor 520 is turned ON to start oscillation. This operation is carried out each time a copy is discharged. It is thereby possible to arrange papers securely up to an arrangeable number of sheets, without affecting a stapling mode.

Title: Permanent-magnet rotary electric machine
Inventor: NAKAMURA MASANORI
IPC: H02K1/27
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of eddy currents by forming each rear-earth permanent magnet attached to one pole of the outer peripheral section of a rotor core so that the magnet may have a trapezoidal cross section in the axial direction. SOLUTION: The magnets of one pole is composed of rectangular permanent magnets 1a-1n which are electrically insulated from each other. The eddy currents which occur in a rotor core 2 concentrate to the surface of a rotor and are discriminated from the penetrating depth of a high-frequency current when the rotor is made of a metal. When the frequency of the current becomes higher and the relative permeability of the rotor becomes larger, the penetrating depth becomes shallower. When the magnet of a rotary electric machine is fractionated and the fractionated magnets are electrically insulated from each other, the routes of eddy currents can be cut off. Therefore, when the magnet is divided in the axial direction or the angular direction of the axial cross section and the divided magnets are insulated from each other, a permanent-magnet rotor which hardly generates eddy currents can be obtained. Each rare-earth permanent magnet is composed of, for example, an Nd-Fe-B permanent magnet, electrically insulated by coating the magnet with epoxy paint, etc., and layered so as to suppress the occurrence of eddy currents.
