Patent JP-S61140126-A (JP)
Title: Manufacture of compound ferrite magnet
Inventor: NAGATA KENJIRO
IPC: H01F41/02
Filed: 1984-12-12
Abstract: PURPOSE:To improve the magnetic characteristics in terms of the coercive force and the residual magnetic flux density with the application of the magnetic materials of the same component, by pressure-forming of the slurry of two kinds of the Sr system ferrite magnetic powder whose average grain size is different with each other. CONSTITUTION:The cavity 26 is separated into the large part and the small part by the sperating plate 30. The slury of the Sr system ferrite magnetic powder whose average grain size is in the range of 0.9-1.1mum is supplied by applying pressure from the one slurry supplying hole 38. The slurry of the Sr system ferrite magnetic powder whose average grain size is in the range of 0.7-0.85mum is supplied by applying pressure from the other slurry supplying hole 40. Both the slurries are oriented by the intense magnetic field which the exited coil 28 generates. The liquid contained in both the slurries supplied by applying pressure escapes outwards through the filter 34 and the pipe 36 and the pre-forming is performed. The separating plate 30 is brought douen at the right time to be picked out of the cavity 26, and the pressing is continued so that the tightly compacted comporite ferrite magnet before sintering is obtained.

Abstract: PURPOSE:To control a plurality of operation patterns in a stable manner by installing an arithmetic operation means, a gain function generation means, a switch-over means and adjusting the opening of a combustion air flow rate control valve in proportion to the opening calculated by this arithmetic operation means. CONSTITUTION:A gain function generator 31 turns a gain calculated in a computing element 28 into the optimum gain during the starting process from the start to the end, using an actual combustion air flow rate control signal as a variable. In addition, a gain function generator 32 uses the actual combustion air flow rate control signal as a variable and turns the gain calculated in the computing element 28 into the optimum gain during the load operation from the start to the end. Moreover, a relay 33 makes a judgement as to the starting end point of an air supply device from the presence of electric energy available in a fuel cell generation plant. When no electric energy is available, the relay 33 enters the gain signal which is the output of the gain function generator 31 into the computing element 28 as an input signal and enters the gain signal which is the output of the gain function generation generator 32 into the computing element 28 as a gain input signal. This constitution makes it possible to carry out stabilized control based on the optimum gain.

Title: Liquid growth method
Inventor: SASAI YOICHI
IPC: H01L21/208
Filed: 1986-11-06
Abstract: PURPOSE:To prevent the fluctuation of the solute concentration of the bottom of a growth solution, and to improve the composition of an extremely thin film layer and the reproducibility and uniformity of film thickness by making the area of an upper hole larger than that of a lower hole in the shape of a solution reservoir for sliding growth and forming a slot in a direction perpendicular to the direction of sliding to the lower section of the solution reservoir in extremely thin-film epitaxial growth through a liquid growth method. CONSTITUTION:When an InGaAsP/InP quantum well type epitaxial layer is shaped, upper holes are made larger than lower holes in the shape of solution reservoirs 2', 3', 4' for barrier layer solutions 2, 4 and a well layer solution 3, and lower holes 8, 9, 10 are each formed to said solution reservoirs 2', 3', 4'. The lower holes 8, 9, 10 are formed to a striped shape in the direction rectangular to the direction 11 of sliding. Since loading density applied to the bottoms of growth solutions is increased and the length of the direction 11 of sliding of the bottoms is shortened in the growth solutions received to the solution reservoirs having such a shape, the convection and vibrations and fluctuation of the solutions of the solution bottoms generated at a time when the slider 11 is slid are inhibited. Accordingly, the variation of the composition of solute concentration in the solutions is suppressed, thus allowing growth having reproducibility and uniformity.

Title: Surface acoustic wave element
Inventor: OKANO HIROSHI
IPC: H03H9/25
Filed: 1993-10-22
Abstract: PURPOSE:To obtain a high electromechanical coupling coefficient by a thin piezoelectric film by forming a surface layer part in contact with the piezoelectric film in a semiconductor crystal system substrate into a high conductive part. CONSTITUTION:This surface acoustic wave element is composed of a silicon crystal substrate 1, a piezoelectric film 2 composed of AIN formed by an epitaxial growth on the surface of this silicon single crystal substrate 1 and an interdigital transducer 3 formed on this piezoelectric film 2. The silicon single crystal substrate 1 has high conductivity. In this case, a high electromechanical coupling coefficient can be obtained by a thin piezoelectric film 2 by the electric filed shielding due to the high conductivity of the silicon single crystal substrate 1. Because the piezoelectric film 2 is formed directly on the surface of the silicon single substrate 1 where crystal orientation is uniform, the piezoelectric film 2 can be allowed to the epitaxial growth, the characteristic of the piezoelectric film 2 can be improved to reduce propagation loss, etc.

Title: Member for mixing
Inventor: AOKI KIYOSHI
IPC: B01F5/00
Filed: 1985-11-27
Abstract: PURPOSE:To enable quantitative instrumentation of resin in a time of use for a long period and to prevent the change of electric insulation characteristics of resin even if abraded powder is mixed in resin by using silicon nitride series ceramics to form a member for mixing.

Title: Toner conveyance device of image formation device
Inventor: MIYAKE NOBUYUKI
IPC: G03G15/08
Filed: 1990-10-04
Abstract: PURPOSE:To securely prevent toner from leaking and scattering from a coupling part where toner is passed from one member to the other member by closing the opening part of the latter member and then separating the both when the former member is detached. CONSTITUTION:Waste toner which is carried from a cleaner falls in the pipe on the side of a waste toner container from a conveyance unit 3 and an opening part 3a corresponding to the end part 1a of a conveyance screw 1. A cup 4a fitted to the end part of the pipe 4 is fitted detachably to the tip projection part of a conveyance path 3, where a shutter member 6 is mounted slidably. When the up 4a is moved to the right, a plate body 7 made of a magnetic material is released from being attracted by a magnet 8 and a the cup 4a comes out of the conveyance path 3, but a plate body 9 made of a magnetic material is still attracted by the magnet 11, so the shutter member 6 slides to the right to shield an opening member 3a before the cup 4a comes out and then the cup 3 comes out of the conveyance path 3 thereafter, so the internal toner is never scattered.
