Abstract: PURPOSE:To provide a cutter for cutting casting having high cutting efficiency and durability for the use of cutting casting in which the generation of a frictional heat is prevented. CONSTITUTION:In a casting cutting cutter, an abrasive grain 1 of diamond or borazon of 40/45# and a grading size ranging from 10-30mu and a hard abrasive grain part 3 in which a solid powder lubricating agent such as boron nitride or molybdenum disulfide is added to a hard abrasive grain 4 such as diamond, borazon, alumina or zirconia are fixed and formed on the circumferential edge surface and side surface of a metallic base 1 consisting of an 36% Ni-Fe alloy or an Fe-31% Ni-5% Co alloy, respectively, by nickel or nickel alloy plating. Since the cutting efficiency is thus improved, and no base shaking is caused, a higher safe tool can be provided, and the cutter is suitable a dry Kimberley type wheel or band saw for cutting and removing finishing of the feeder heads, gates, and weirs after casting general pig castings and ductile iron castings for mechanical structure, and for cutting of casting pipelines for water works and sewerage.

Title: Semiconductor memory
Inventor: KITAGUCHI YUKIO
IPC: H01L27/10
Filed: 1990-07-25
Abstract: PURPOSE:To reduce the noise of an output buffer without increasing current consumption by first turning on an n-channel transistor having smaller conductance, and later turning on an n-channel transistor having larger conductance. CONSTITUTION:Between a power source and a ground, (p) and (n) channel transistors Pt and Nt are successively serially connected, and between the connecting point and the ground, an n-channel transistor NNt is connected. When sense signals DAT0,... change the levels with the transition of address input signals A0,... by an output control circuit 7, the Pt is turned off and the NNt, which conductance is smaller than that of the Nt, is turned on based on the sense signal before the level change at the level change timing of a clock signal. Continuously, the Nt having larger conductance is turned on in the state of turning off the NNTt based on the sense signal after the level change at the level recovery timing of the clock signal. Thus, the noise of an output buffer 6 can be reduced without increasing current consumption.

Abstract: PURPOSE:To suppress the cracking by a method wherein, in the section in the peripheral direction of a tire, an angle of a cut wall, running to a tread part in succession to the top part of a platform formed in a lateral groove, with the surface of the tread part is decreased to a value lower than an angle of the lateral groove with the tread surface. CONSTITUTION:Three block trains of a block train 18, positioned at the central part of a tread part 12 on which wide bending is applied during drive and braking and two block trains 24 and 24 located adjacently to the aforesaid block train, are formed. A platform 38 is formed in lateral grooves 16 and 22 by which a plurality of blocks positioned away from each other in the peripheral direction of a tire are partitioned.

Title: Connecting method of terminal part and metallic lead in ceramic substrate
Inventor: KONDO KAZUO
IPC: H01L23/50
Filed: 1986-08-29
Abstract: PURPOSE:To obtain a stable connecting part characterized by excellent heat resistance, by forming a barrier layer, which is formed by mounting inactive metal such as Ni, Pd, Pt and the like with respect to Ag on the surface of the terminal part of a substrate, using pure Ag as a soldering material through said barrier layer, and soldering a metal lead. CONSTITUTION:A barrier layer 4 is deposited on a ceramic substrate comprising ceramics characterized by a dielectric constant of 7.0 or less and a thermal expansion coefficient of 5 X 10<-6> or less or on the surface of a terminal part 3, which is guided out to the outer surface of an IC package. The barrier layer 4 is formed by plating Ni having a thickness of about 10 mum on the metallized surface of the terminal part 3. A metal lead 5 comprising Fe-Ni alloy (42Alloy) is soldered to the terminal part 3 of the substrate through the barrier layer 4 at a soldering temperature of 1,000 deg.C by using pure Ag as a soldering material. Because of the ductility of the pure Ag, the soldering material itself serves the role of a buffer material, which absorbs stress and strain. Thus cracks in the substrate is prevented. Diffusion of Ag into the metallized layer of the terminal part of the substrate is suppressed by the barrier layer. Since the occurrence of resorption can be prevented, rigid bonding becomes possible. The highly reliable connecting part characterized by excellent heat resistance is obtained.

Abstract: PURPOSE:To obtain gaseous N2 in high yield and with quick cycle operation by controlling introduction of air into an adsorption tower in a gas separation process so as to cause intermittent change in the flow rate of the air in an adsorbent column. CONSTITUTION:Gaseous N2 (product gas) is produced from air (feed gas) in accordance with cycles consisting of an adsorption stage and a desorption stage. In the midway of or after a stage for elevating the pressure in an adsorption tower to a specified highest pressure, gaseous N2 is delivered to a product reservoir 18 through a pipe 33 by opening or closing an N2 delivery valve 14 intermittently in accordance with a predetermined valve sequence (adsorption stage). Then, unnecessary gas (gaseous O2) in the adsorption tower 11 is discarded to atmospheric air through a valve 15, pipe line 31, and a pump P from a valve 16 by closing valves 12, 13, 14 and opening valves 15, 16. A valve 17 is then opened and closed intermittently, and desorption of residual O2 is prompted (regeneration stage) by flowing a part of the product gas in the product reservoir 18 toward counter current direction into the adsorption tower 11 (purge operation). Thus, one cycle is completed.

Abstract: PURPOSE:To reduce noise and improve stability of oscillation by disposing electrodes expanding in the direction at a right angle to the cathode axis in the area near the cathode at the area near the end hut rather than in the center of cathode. CONSTITUTION:A conductive cylindrical base material 71 having a diameter smaller than the helical internal diameter of cathode 25 is disposed within said cathode 25 and a helical segment 72 protruded between helixes of the cathode 25 is integrated to said base material 71. An envelope surface formed by the edge of helical protruded segment 72 is formed like a drum surface. Namely, expansion in the radius direction is more distinctive in the area near the end huts 51a, 51b and it is reduced at the center of cathode 25. The positive ions are seized from the side of edge of electrode 70 but any influence is not given to the major portions of oscillation. Therefore, excellent stability of oscillation and characteristic of dark current can be ensured.

IPC: F02D41/22
Filed: 1983-10-28
Abstract: PURPOSE:To eliminate risks of blockage and corrosion of an intake-air pressure introducing passage for controlling the air-fuel ratio of an engine, and as well to make it possible to carry out the feed-back control of the air-fuel ratio, by periodically feeding air into the intake-air pressure introducing passage when the latter is scavenged, to blow off and remove residues. CONSTITUTION:When the running time of an engine reaches a predetermined time, drive current is fed to a solenoid 19 from a control unit 6 for a previous set predetermined time period to open a shut-off valve 18. Then air flows from an air passage 17 through an intake-air pressure introducing passage 15, and is blown off into an intake-air pipe line 11 to blow off and remove residues. During this time period a safe function circuit 20 processes data for the feed-back control of the air-fuel ratio so that an electrical signal from a pressure sensor 6 is not delivered to feed-back control elements. When the shut-off valve 18 is closed, the normal feed-back control is resumed.
