Title: Sediment excavation machine and tooth member for sediment excavation
Inventor: USAMI KENICHI
IPC: C21D9/22
Filed: 1994-01-13
Abstract: PURPOSE:To improve abrasion resistance as an excavation tooth by melting and forming steel having the prescribed composition into a tooth shape and, then, hardening and tempering the steel within the prescribed temperature zone. CONSTITUTION:A steel material containing each of elements such as C, Si, Mn, P, S, Ni, Cr, Mo, B, V, and Nb within the range of the prescribed weight percentage is used as the material of an excavation tooth 1 plugged into an adapter 3 mounted on a bucket 3 and secured with a lock pin 4. The steel material having such a composition is melted and formed into the prescribed shape as the tooth 1 and, then, subjected to thermal treatment within the zone of temperature including 900 to 1000 deg.C hardening treatment and 300 to 600 deg.C tempering treatment. Also, material hardness can be enhanced by using such a material as having Vickers hardness kept between 550 and 700, and further having a mixed composition where a complex carbide mainly composed of Nb is precipitated into a matrix of tempered martensite, thereby contributing to the wear resistance of an excavation tooth member.

Title: Operational control device of air conditioner
Inventor: TAKAHARA TSUTOMU
IPC: F24F11/02
Filed: 1985-01-10
Abstract: PURPOSE:To economically and healthily control the cooling operation and contrive to improve the operability of an air conditioner by a method wherein an outside air temperature detecting means to detect the temperature on outdoor side is provided and the operation of the air conditioner by a timer is stopped, when the outside air temperature reaches the set value. CONSTITUTION:When the outside air temperature is lower than the arbitrarity set temperature, a temperature sensitive element 26 shows higher resistance value, resulting in raising the voltage Vx divided in the ratio of the resistance of the element 26 to that of a resistor 27. In this case, when the voltage Vx becomes higher than the voltage Vo divided in the ratio of the resistance of a resistor 28 to that of a resistor 29, the output of a comparator goes to 'H', resulting in driving a relay coil 17 through a driver 31 and turning OFF a normally closed relay contact 4. Thus, the electrical circuit stops a compressor and a fan. straightly speaking, even when the operation by a timer is continued, if the outside air temperature goes down below the set temperature, said operation by a time is stopped.

Title: Area machining method
Inventor: KISHI HAJIME
IPC: G05B19/4093
Filed: 1984-01-10
Abstract: PURPOSE:To improve the work efficiency without leaving any unmachined portions in the center area by dividing straight lines, which connected the center of gravity of an area to the vertexes of the area, into the prescribed number and by moving a cutting tool along each closed path connecting those division points with the distance between the closed paths being changed according to their shapes. CONSTITUTION:In a processor, after a center of gravity W of an area is obtained, when lines L1-L10 connecting the center of gravity W to vertexes P1- P10 of the ara do not intersect an off-set curve OFC, the lines L1-L10 are divided into the prescribed division number n; the coordinate values of these division points Pa1-Pn1...Pa10-Pn10 are obtained and stored in RAM. Next, plural closed paths CPT1-CPTn are formed by connecting these division points Pa1- Pa10...Pn1-Pn10, and the processor shifts a cutting tool to a point Pa2 along the 1st closed path CPT1, and thus the cutting operation is performed along the path CPTn in succession. In this way, by moving the cutting tool along the curve OFC in accordance with the data specifying the off-set curve OFC stored in RAM, the area machining process can be finished in a short time without leaving any portions unmachined.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a high-dielectric capacitor and a capacitor that is manufactured by it. SOLUTION: A conductive plug 303 is formed on a semiconductor substrate 300 and a barrier layer 307a consisting of a high-melt-point metal and a filler is formed on it, thus shielding the diffusion path of metal and oxygen by filling a crystal grain boundary being present in the barrier layer into the filler. Then, after lower electrodes 309a and 311a and a high-dielectric film 313 are sequentially formed on the barrier layer 307a, a high-temperature heat treatment is performed in oxygen atmosphere. An upper electrode 315 is formed on the high-dielectric film 313, thus improving the diffusion prevention function of the barrier layer 307a and an electrode layer and hence obtaining a reliable high-dielectric capacitor that can be applied to an ultra-high-integration semiconductor device.  Especially, the diffusion of metal or oxygen can be prevented even by a barrier layer that is approximately 100Å, an area where a film other than platinum contacts the high-dielectric film can be minimized and a high-dielectric capacitor with improved diffusion prevention characteristics and improved leakage current characteristics can be obtained.
