Title: Manufacture of anisotropic magnet
Inventor: OSHIMA MITSUAKI
IPC: H01F41/02
Filed: 1985-06-13
Abstract: PURPOSE:To obtain the anisotropic magnet having characteristics higher on one pole end face than on the other pole end face by a method wherein magnetic powder is compression- molded by applying a magnetic field to molding space in such a manner that it crosses at right angle with the direction of compression so that the density of magnetic flux on one die surface is made higher than that of the other die surface. CONSTITUTION:The entire die 1 is composed of the left side part 13 and the part 12 consisting of the right side part 11 and a non-magnetic body or a material having small permeability. Magnetic powder 4 is packed up in the cavity located at the center part of the die, and the magnetic powder 4 is compression-molded using the upper and the lower punches, and the impressed magnetic field M is brought in the orthogonally intersecting direction with the direction of compression. When the parts 11 and 13 of left and right dies are made of material of ferromagnetic substance of the same quality, if the cross-sectional area of the left side die part in the magnetic direction M is set at SL and that of the right side die at SR, the magnetic flux density of the right side die surface becomes SL/SR time of that of the left side die surface. As a result, the density of magnetic flux of the right side part of the die surface is made higher than that of the left side part of the die, and the degree of magnetization of the magnetic pole B of the magnet located close to the right side die surface becomes higher than that of the other magnetic pole A.

Title: Feeding device
Inventor: YAMADA TADASHI
IPC: B65G59/06
Filed: 1985-06-13
Abstract: PURPOSE:To enhance the efficiency of operation to feed works one after another by stocking works in radially arranged frames of a horizontal axis rotary wheel, transferring them to a fixed guide when said frame faces right down, and by feeding to a specified place by the use of a feeder. CONSTITUTION:Works 3 are stocked one after another in work stocking frames 2 of a rotary wheel 1, and when a frame 2 faces right down, a stopper 4 is opened to allow works therein to fall into a fixed guide 5 by own weight with aligned condition retained, and then they 3 fall onto a work placing table 20 one after another from the undermost lying one to be sent to a specified place on said table 20 by a pushing member 8 of a work feeding device 6. Here the bottom of said guide 5 is apart from the table 20 at a height to allow passage of only one work 3, so that they are sent off one after another. During pushing- out of any work 3 by a pushing member 8, the subsequent one 3 is placed on a receiving piece 9, and when the pushing member 8 has returned to its back position, the work 3 falls onto the table 20 from said receiving piece 9 to be sent forward by the next pushing member 8 advancing.

Title: Air conditioner for vehicle
Inventor: HASHIMOTO SATOSHI
IPC: F24F11/02
Filed: 1978-10-18
Abstract: PURPOSE:To avoid to give load to an engine for acceleration by giving an electromagnetic clutch a separate state when either the car speed or the speed of engine revolutions is suddenly increased. CONSTITUTION:A voltage difference detector 14 is used to receive a DC voltage inversely proportional to the car speed or the speed of engine revolutions from a smoothing circuit 13 constantly for memorizing as an electric charge in a condenser C8. When the DC voltage output from the smoothing circuit 13 is suddenly reduced to give a minus voltage difference against the memorized voltage because of the sudden increase of the car speed or the speed of engine revolutions, the charge of the condenser C8 is discharged between the collector and the emitter of a transistor T1 to give output until the voltage difference is gone. This output is transmitted to a power circuit 15 to give an electromagnetic clutch 3 a separate state. Consequently, for acceleration, the load of the necessary power to drive a compressor in an air conditioner is prevented to be added to the engine.

Title: Semiconductor substrate
Inventor: INOUE RIICHI
IPC: H01L21/762
Filed: 1990-05-18
Abstract: PURPOSE:To avoid the deterioration in the performances of a semiconductor element formed in a single crystal semiconductor layer by a method wherein the single crystal semiconductor forming hetrojunction with a single crystal silicon layer is formed on the single crystal silicon layer in thickness not exceeding 1500Angstrom laminated on a holding substrate through the intermediary of an insulating film. CONSTITUTION:A single crystal semiconductor layer forming heterojunction with a single crystal silicon layer 3 is formed on the single crystal silicon layer 3 in thickness not exceeding 1500Angstrom  laminated on a holding substrate 1 through the intermediary of an insulating layer 2. That is, in consideration of the relation between the film thickness of the SOI layer 3 and the density of dislocation occurring in a single crystal semiconductor (GaAs) layer 5 normally about 2-3mum thick heteroepitaxially grown on the SOI layer 3, the thickness of the SOI layer 3 is made sufficiently thinner at about 50-1500Angstrom  while that of the single crystal semiconductor layer 5 is made sufficiently thicker than that of the SOI layer 3. At this time, the stress imposed by the crystal lattice caused at the heterojunction part and the inconsistancy in the thermal expansion coefficient can be absorbed into the deformation of Si crystal lattice in the SOI layer 3. Through these procedures, the crystalline quality of the single crystal semiconductor layer by heteroepitaxial growth can be enhanced.

Abstract: PURPOSE:To obtain a high-purity SiC whisker, by dispersing a transition metal (compound) such as Fe or Ni in amorphous powder composed mainly of Si and C, having a specific C content and produced by a vapor reaction and treating the dispersion in a non-oxidizing gas atmosphere. CONSTITUTION:Amorphous spherical powder composed mainly of Si and C and having a C content of 25-50wt.% is produced by the vapor-phase thermal decomposition reaction of an inorganic Si compound and a hydrocarbon or various organic Si compounds. A transition metal such as Fe, Ni or Co or its compound is dispersed in the produced spherical powder and the dispersion is heat-treated in a non-oxidizing gas atmosphere (e.g., He or H2) at 1,400-1,800 deg.C under a condition to complete the reaction in 0.5-10hr. The SiC whisker produced by the above process has a diameter of 0.05-1mum and an aspect ratio of about 5-100. Since the SiC whisker is almost free from unreacted silica, the post- treatment of the whisker is unnecessary.
