Abstract: The pump has an inlet and an outlet for the fluid to be pumped as well as a housing (11) which contains an elongated internal chamber (31) which is defined at one end by an end section (17) and in which a piston (35) is displaceably guided. The inlet is connected via a first non-return valve (63) to the pump chamber (33) located between the end section (17) and the piston (35), which chamber in turn is connected via a second non-return valve (71) to the outlet. The piston (35) is fitted with a third non-return valve (99), which additionally connects the inlet to the pump chamber (33) and during the intake cycles, particularly in their initial phases, allows pressure drops, which in the pump chamber (33) might cause liquid fluid to be converted into gaseous fluid, to be largely avoided. …<IMAGE>…

Abstract: A tape handling apparatus comprising rotation detecting means (138,139) for detecting the rotation of a pair of reel supports, and control means (180) for controlling the operation of a capstan motor and a pinch roller pressing mechanism. When the detecting means detects the supply reel support stopping rotating while a tape is being rewound on the supply reel from the take-up reel, the control means moves a pinch roller away from the capstan and reversely rotates a capstan motor. Consequently, a slack portion of the tape between the capstan and a head cylinder is wound up on the take-up reel by the operation of the take-up reel support.

Abstract: In a power assistance system for a vehicle steering mechanism fluid pressure providing the assistance is supplied from a pump (4) driven intermittently by an infinitely-variable electric motor means (5). For a rack and pinion mechanism (1) fluid pressure chambers (6, 7) are formed by sealing boots (8,9) at each end of the rack (3), and are connected through the pump (4), which is operative to create a pressure differential between the chambers, and thus across the rack (3) to provide power assistance. The electric motor (5) is energised as required to drive the pump (4) in the appropriate direction, and when the motor and pump are inoperative fluid is allowed to flow freely between the chambers (6, 7) to accommodate fluid displacement as a result of unassisted operation of the steering. The pump (4) is preferably a turbine pump, which allows fluid flow when inoperative. The system provides power assistance efficiently, and relatively cheaply.

Abstract: In a semiconductor integrated device having undecided voltage portion pairs (N₁ , N₁′, ... , N m  , N m ′), a signal line (φ) crossing over or under the undecided voltage portion pairs, and a decided voltage portion (N₀ , N m+1 ), a noise source (N₀′, N m+1 ′) equivalent to the signal line is provided between the undecided voltage pairs and the decided voltage portion. This noise source, which may be an additional conductor (X₁ , X₁′,) branching off from the signal line ( φ), compensates for the difference in capacitance of an undecided voltage portion at the edge of an array from that of internal undecided voltage portions; this ensures that voltages induced in the various portion pairs due to the signal line (φ) are substantially equal, eliminating unwanted voltage differences between the undecided voltage portions.

Abstract: An acidic aqueous cleaner, preferably in micro-­emulsion form, which is of a pH in the range of one to four and is useful for cleaning hard surfaced items, such as bathtubs, sinks, tiles and porcelains, and even some such items which are not acid resistant, such as those of a European enamel known as zirconium white enamel, comprises synthetic organic detergent, such as a mixture of anionic and nonionic detergents, e.g., sodium paraffin sulfonate, higher fatty alcohol ethoxylate sulfate and higher fatty alcohol or phenol ethoxylate, carboxylic acid, e.g., mixture of succinic, glutaric and adipic acids, and phosphonic acid, e g., aminotris(methylenephosphonic acid) in an aqueous medium. Preferably a phosphoric acid is present to further improve protection of such European enamel surfaces. 
     The acidic cleaner is useful to remove soap scum, lime scale and grease from surfaces the mentioned items without adversely affecting such surfaces, and removals of the scum, scale and grease is easy, being effected by applying the microemulsion to the surface to be cleaned, followed by wiping it off. Although the cleaned surfaces may be rinsed that is not necessary and the surfaces will be left clean and shiny after wiping, even without rinsing, or with minimal rinsing. 
     In the described emulsions the carboxylic acid components effectively remove soap scum and lime scale, the detergents remove greasy soils and promote effective contact between the acid and the surfaces to be treated, and the combination of phosphoric and phosphonic acids prevents acidic attack of the dicarboxylic acids on the surface being cleaned, with the phosphoric acid increasing protective action of the phosphonic acid component.

Abstract: This invention relates to a method and an apparatus for forming a film, which are suitable for forming a film of a semiconductor, dielectric, metal, insulator, or organic substance. In order to form a film (17) of high purity and quality at high speed, a particle beam (16) such as an ion beam, an electron beam, or a plasma is applied to a sputtering target (9) comprising a substance formed by bonding atoms or molecules with either van der Waals forces or hydrogen bonding forces, the particles are sputtered thereby from the target (9), fly in the space in the vacuum chamber (7), reach the substrate on which they are deposited to form a desired film (17). To form an organic film free of pinholes, impurities, or disorder in the molecular composition and arrangement in a large area at high speed, a particle beam (16) of about 10 eV or less is applied to the target (9) comprising an organic compound disposed in a vacuum. The particle beam (16) has energy high enough to break the van der Waals bonds between the molecules of the organic substance but not the covalent bonds between the atoms. The sputtered particles from the target (9) are deposited on the substrate (10) to form a film (17) of the organic compound.

Abstract: A conductive oxide film (2) is formed on a substrate (1) at a low temperature. The formed conductive oxide film (2) is not very dense because of the low temperature. Therefore the formed conductive oxide film (2) can easily be etched by an etchant having a weak etching capability. And by the etching a pattern of the formed conductive oxide film (2) is produced. The patterned conductive oxide film is oxidized at a temperature in the range of 100-­400°C. In this way a conductive oxide pattern is produced in a shorter time in the method of the present invention than in a conventional method and the conductive oxide pattern produced by the method of the present invention has the almost same resistivity as the conductive oxide pattern produced by the conventional method and has an improved pattern edge and an improved reproducibility.

Abstract: An improved semiconductor memory device having a memory array, a dummy celland a redundancy cell column (RLC) is disclosed. At least one dummy capacity cell is connected to the reference bit line (DBL) to which the cell is connected, and also to a redundancy bit line (RBL) to which redundancy cells (RMC) are connected. Therefore, since a capacity on the reference bit line (DBL) is roughly equalized to that on the redundancy bit line (RBL) by these dummy capacity cells, it is possible to prevent erroneous potential level determination by a sense amplifier (SA) for comparing both the potentials on both the bit lines, without being subjected to the influence of supply voltage fluctuations.
