PURPOSE:To increase discharge performance and cycle life by arranging in a specified ratio relation of thickness of electrolyte holding body and that of a plate, and relation of thickness of a plate group and inner width of a container. CONSTITUTION:Thickness of electrolyte holding body when it is pressed at a pressure of 20kg/dm<2> is specified to 0.65-1.5 times that of a cathode plate, and free ...

PURPOSE:To smoothly operate a friction clutch depending on the running condition of a vehicle, by using the negative pressure of an intake pipe and the speed of the vehicle to control air flowing out of the atmosphere chamber of an actuator for operating the friction clutch, to regulate the engagement speed of the clutch. CONSTITUTION:In starting, a control valve 30 is closed because of the strong...

A long, thin annular belt-like channel is designed for use in sedimentation field flow fractionation. This channel, which may be contained in the rotor of a centrifuge, has a generally rectangular cross-section. It has an inlet positioned to introduce particulates (includes particles and/or macromolecules) approximately at the radial distance from the outer wall that is the equilibrium distance re...

A long, thin annular belt-like channel is designed for use in sedimentation field flow fractionation. This channel, which is the rotor of a centrifuge, is designed to maintain its thickness dimension constant and yet facilitate its manufacture and cleaning by forming the rotor of a double mating ring in which the inner ring is split. This permits the inner ring to conform to the outer load carryin...

PURPOSE:To reduce the size and weight of a transmission mechanism, by fitting a part of a rotary shaft in a hollow rotary shaft, providing spline parts on these rotary shafts, and installing a gear which can slide to be engaged with one of the spline parts. CONSTITUTION:Bearing fitting parts 12a, 12b are provided on both the ends of the rotary shaft 12. A spline part 12c and a bearing fitting part...

A drill bit for well or deep drilling comprises a steel connection member (1) with a threaded plug (2), for connecting to a drilling string or other rotary drive, and a head (3). Cutting members (11) are mounted on strip- shaped vanes (10) which are inserted in recesses in the head (3) and welded or soldered thereto (as at 12). The vanes (10) comprise a lower portion (13) of steel to which a base ...

PURPOSE:To detect the runaway of a program completely by discriminating whether the contents saved in a stack memory are a return address or register contents, and monitoring a processing execution state. CONSTITUTION:An address bus 2 and a data bus 3 are connected to respective memories 4, 5, 6, and 7 for a program, data, stack, and flag through a CPU1, the bus 3 is connected to an instruction de...

PURPOSE:To prevent a master processor from disabling due to a fault occurring to a slave processor by releasing the master processor from a wait state without fail when the master processor is kept in the wait state continuously for longer than a specified time. CONSTITUTION:The master processor 1 is provided with a monitor timer mechanism 11, and salve processors 2 and 3 are provided with NORDY c...

A tire building apparatus having main frame means, and rotatable tire building drum means supported by the main frame means. A pair of tire bead placing and end ply bag turn-up ring means are supported on the main frame means and are movable axially inwardly and outwardly longitudinally of the drum means. Positive stop means are carried by the main frame means and are engageable by the ring means ...

The novel herbicidal compositions contain, as active ingredients, a) 5 to 95 parts by weight of at least one compound of the general formula I and b) 95 to 5 parts by weight of at least one herbicidal compound which does not come under the formula I. They can also be composed of a mixture of components a) + b). In formula I, the symbols R1, R2, X and n have the meanings given in Paten...

A tyre building apparatus has two end drums 3, 3a disposed at respective ends of an intermediate drum 2 comprising a sleeve 39 pneumatically expandable to shape to toroidal form that portion of a tyre carcass which is disposed between the beads. The end drums 3, 3a include bead clamping members 48, 48a and ply turn-up bags 49, 49a, and together with the ends of the sleeve 39 are connected to carri...

The subsurface position of a blowing well with respect to an adjacent relief well is determined by detecting at a plurality of axially and tangentially spaced locations in the relief well acoustic waves emanating from a subsurface location of the blowing well. The distance between the wells is calculated on the basis of the difference in times of arrival of the waves at said axially spaced locatio...

The invention provides a process for making ferro-nickel shot from a molten alloy bath including a granulating adjuvant containing silicon. The resulting shot can be used as soluble anodes for use in electroplating in which a ferro-nickel plating is applied to a substrate.

A silicon semiconductor device having contacts which include tantalum. The tantalum is useful in particular for fabricating Schottky barrier diodes having a low barrier height. The method includes: precleaning the silicon substrate prior to depositing the tantalum; depositing the tantalum at low pressure and low substrate temperature to avoid oxidation of the tantalum; and sintering the contact to...
