Title: Obstacle avoiding system for mobile robot
Inventor: OKURA KAZUHIRO
IPC: B25J9/10
Filed: 1992-04-24
Abstract: PURPOSE:To decide in real time the traveling direction of such a robot that contains a small-scale processor and also to surely avoid the mobile obstacles by calculating the fault potential of the position of a mobile robot set after a minute time and deciding the obstacles with the comparison carried out be tween the calculated fault potential and the prescribed threshold value. CONSTITUTION:A mobile robot 1 does not have so much difference of the moving ability against a mobile obstacle 3 and can easily follow a mobile target 4 with its own moving ability. The robot 1 decides whether its traveling direction should be positively changed against the target 4 or not after a minute time in order to avoid the obstacle 3. Under such conditions, a fault potential function (f) which simply increases is set and the threshold values are previously set for both dagnerous and safe areas. Then a processor 2 of the robot 1 controls the direction of the robot 1 to avoid the obstacle 3 when the fault potential calculated at its own position after a minute time is smaller than the threshold value set for the safe area.

Filed: 1990-04-23
Abstract: PURPOSE:To reduce deformation of the ceramics sintered body by applying the surface of a molded body with the mixed powder consisting of Si3N4, BN and a sintering adjuvant and sintering the molded body in a N2 atmosphere of normal pressure or pressurization. CONSTITUTION:After adding and mixing the proper amount of a sintering adjuvant selected from among MgO, Al2O3 and Y2O3, etc., and water with Si3N4 powder, the mixture is dried and the dry powder is molded into a required shape.

Title: Electrodeposited grindstone
Inventor: MORIMOTO SATOSHI
IPC: B24D3/06
Filed: 1990-04-23
Abstract: PURPOSE:To keep the sharpness of more than the specified level all the time as well as to make highly efficient grinding operation performable by dispersing resin grains over a plating layer holding abrasive grains. CONSTITUTION:When a hard material is ground, each abrasive grain 13 projected out of a plating layer as far as about 50-20% in grain size works on removal of a workpiece. Next, if grinding continues, a projection of the abrasive grain 13 is worn out and the projecting amount becomes less than about 20% whereby grinding force increases, and when force to be imposed on each abrasive grain 13 grows larger, a plating layer 14 holding the grain 13 is broken down, and the abrasive grain 13 worn out together with the plating layer 14 is dropped down, thus a new grain is projected instead. At this time, resin grains 20 being dispersed in the plating layer 14 controls the extent of strength in the layer 14, and when force of more than the specified level is imposed on the plating layer 14 in and around the abrasive grain 13, there is such an action as causing a state of breaking the plating layer 14.

Title: Manufacture of semiconductor device
Inventor: SAITO KENJI
IPC: H01L21/28
Filed: 1986-05-06
Abstract: PURPOSE:To suppress Si precipitation at a contact hole part, promoted by a BPSG film in existance, and obtain stable contact resistance, by using two layered PSG and BPSG films as insulating films for surface protection and flattening, and besides removing the BPSG film at a peripheral part of the contact hole. CONSTITUTION:A base oxidizing film 2 is formed on a Si substrate 1, and a PSG film 7 is piled thereon by CVD method, and a BPSG film 4 is piled moreover. Then, a hole is bored in the BPSG film 4 so that its width becomes a little larger than that of the contact hole, by using photoengraving technology. Besides, a contact hole is formed in the PSG film 7 by using the photoengraving technology. Then, evaporation of an aluminium film is performed all over the surface, and patterning is performed by using the photoengraving technology, to form aluminium connection 5. Thereafter, hydrogen processes are performed for 30 minutes at 450 deg.C. Such two-layer structure, in which the PSG film 7 and the BPSG film 4 are made to be respectively the lower and upper ones, prevents Si from precipitating into the aluminium connection 5 in the hydrogen processing, capable of obtaining excellent flatnees.

Title: Method and apparatus for purifying exhaust gas
Inventor: HACHINAGA MORIJI
IPC: F01N3/20
Filed: 1995-04-28
Abstract: PURPOSE: To provide a method for purifying exhaust gas which reduces catalyst poisoning by SOx contained in exhaust gas and at the same time controls H2 S releasing into the air. CONSTITUTION: When an upstream side catalyst converter CA-1 and a downstream side catalyst converter CA-2, which are installed in an exhaust duct line of an engine 2, are in a warming condition, an air fuel ratio perturbation is conducted in which the air fuel ratio is temporarily changed alternately between a rich region and a lean region on the basis of a theoretical air fuel ratio. When the catalyst converter CA-1 is in a rich atmosphere, SOx stored in the converter CA-1 is reduced into H2 S, and the H2 S is released from the converter CA-1. In this way, the poisoning of the converter CA-1 by SOx is reduced. Next, the capture of released H2 S and the oxidation of the released H2 S are conducted on the converter CA-2 side, reducing H2 S releasing into the air.

IPC: E02D17/18
Filed: 1985-05-17
Abstract: PURPOSE:To prevent the breakage of arched portion by avoiding the horizontal displacement of the end portion of panels by the force components of earth pressure in the supporting portion by providing an arched PC steel material between the left- and right-handed ends of the panel of an arched cross section and giving a prestress to it. CONSTITUTION:A rack portion 2 of an L-shaped cross section is horizontally formed on the recessed side of a panel 1, and a PC steel material 3 is horizontally thrust through a hole 4 formed in the corners of the rack portion 2. The PC steel material 3 is tensed, its both ends are fixed by wedge or nut 5 to divide the earth pressure P into force components P1 and P2 on left and right- handed end portions, and thereby a prestress S is given to the PC steel material 3. No horizontal displacement could occur in the end portions of the panel 1 unless the force components of the earth pressure exceed the prestress force S in the supporting portion. The panel can thus be used as tougher type.

Title: Wire for welding
Inventor: OOSHIMA SHIYUNJI
IPC: B23K35/08
Filed: 1980-07-30
Abstract: PURPOSE: To obtain a welding wire that enables stable welding by twisting 3 strands into one body and making lines connecting the center of each strand a regular polygon in a cross section and thereby reducing thermal conductivity.  
     CONSTITUTION: Three strands 1a, 1b, 1c of equal cross section are twisted to form a wire for welding making lines connecting the center of each strand a regular triangle in a cross section. Again, four strands 2a, 2b, 2c 2d of equal cross section are twisted to form a wire 2 for welding making lines connecting the center of each strand a regular square. Since strands in these welding wires make linear contact to each other, the condition in the case of a filler wire is near to that when each strand melts independently. Accordingly, heat in the molten pool is not taken away and welding of low heat input is made possible. In the case of consumable wire for welding, temperature rise due to heat generation through internal resistance of each strand becomes large to increase melting speed and lower critical current.
