Filed: 1994-03-30
Abstract: PURPOSE:To obtain uniform grain size by such a processing method that a breaking operation is easy, the cutting loss is small and waste chips can be easily collected at low cost, by pulverizing a specified polycrystalline ingot into particles whose surfaces are mostly cleavage planes and using these particles as the source material particles. CONSTITUTION:A polycrystalline ingot containing single crystal grains of >3mm cube by >30% of the whole volume is not formed into a wafer but once directly pulverized with a jaw crusher at 60 to 250 times/min reciprocating speed. The pulverized material is sifted through a 1 to 3-mm mesh to obtain particles of 0.5-6mm thickness and 4 to 20mm length and width. Most of pulverized particles are single crystals so that pulverization is not needed for a device maker. A III-V compd. semiconductor single crystal has brittle cleavage on {110} plane. Figure (1) shows the plan view of the principal planes and figure (2) shows the perspective view. When the material is used as a substrate to grow a crystal, a wafer having (100) plane as the surface is usually used. This block crystal has 26 planes and 12 of these are cleavages. The crystal cracks along these cleavages. The obtd. particles are sifted to remove a powder, etched with an etching liquid and then washed with water.

Title: Synthetic resin insulating brake wheel of type withstanding snow water
Inventor: SASAHARA SHIGEMI
IPC: F16D69/00
Filed: 1978-07-14
Abstract: PURPOSE: To provide the above-identified structure, which is free from reduction of the frictional property even in case of intrusion of snow water into contact with the frictional surface and also has insulating property, by incorporating sintered metal blocks such that they occupy a paritcular proportion of the frictional surface area of the synthetic resin insulating brake wheel.  
     CONSTITUTION: Sintered metal blocks 1 each have tapering end surfaces 7 and are provided on the side opposite the side constituting a frictional surface with endwise projections 8. Thus, they are firmly secured within the synthetic resin brake wheel 2, and their frictional surface occupies 15 to 80% of the entire frictional surface area. The frictional surface of the sintered metal blocks 1 is porous and prevents formation of a lublicating film of water wetting it, and also it generates heat of friction to cause the water wetting it to be quickly removed by evaporation and thus prevent reduction of the coefficient of friction. Also, since the brake wheel is formed by thermal pressure molding of a synthetic resin incorporating an insulating material, the frictional surface 3 is insulated from a brake wheel 4.

Title: Method and system for recognizing constitution of hub
Inventor: NAKAJIMA JUNKO
IPC: H04L12/44
Filed: 1994-04-25
Abstract: PURPOSE:To perform the network management adapted to actual network constitution. CONSTITUTION:A management device M successively selects MAC addresses, which are stored in an address table 1, of hubs Ha to Hf connected to the network by an address selecting part 2 and generates a port inhibition packet to send it to selected hubs. Each selected hub disables ports other than the port connected to the management device M, and an address request packet is broadcasted from the management device M to all hubs. Each of hubs Ha to Hf receives the address request packet to return its own MAC address to the management device M and releases disabled ports, and this operation is repeated till all MAC addresses in the address table 1 are selected. A hub constitution recognition part 7 recognizes the hub constitution in accordance with correspondence relations between MAC addresses of selected nuts and MAC addresses or hubs from which the return packet is received.

Title: Autonomous control-method three dimensional position holding device
Inventor: OZAWA TAKEKI
IPC: H02N15/00
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily hold an object at any position in space without using a complicated device by holding the object in space by autonomous control using induced current. SOLUTION: A permanent magnet 3 is embedded in an object and an electromagnet constituted of a superconductive coil 1 is embedded in a wall 4. The object is placed at any target three-dimensional position and this position is defined as a reference on. At this point, current in the superconductive coil 1 is regulated to zero. In the object goes away from the reference position, induced current is generated in the superconductive coil 1 and then magnetic force is developed to attract the object back to the reference position. ON the contrary, if the object is brought close to the reference position, induced current in the opposite direction is generated and thereby repulsion force is developed to put the object back to the reference position. By this method, the objective can be kept at any position in space autonomously.
