Title: Fluid pressure brake control apparatus for vehicle
Inventor: ARIKAWA TETSURO
IPC: B60T8/48
Filed: 1990-08-02
Abstract: In a fluid pressure brake control apparatus for controlling braking-slip and driving-slip of vehicle wheels and including fluid pressure control valves (47, 48) for connecting a fluid pressure source (13) for driving-slip control and a master cylinder (1) for wheel brakes (49a, b), a valve apparatus (42 A, B) is arranged between the control valves and the master cylinder, and between the control valves and the pressure source, the valve apparatus taking a first condition (D, F) connecting the control valves to the master cylinder, a second condition (E, G) connecting the control valves to the fluid pressure source, and a third condition (E, F) in which the control valves are cut off from both the master cylinder and the fluid pressure source to prevent the high pressure of the latter from being applied to the master cylinder. Further a fluid pressure pump (41) discharges fluid, when the brake pressure is lowered by the control valves, to the valve apparatus and thence the pressure source. The two valves (42A, 42B) of the valve arrangement may be combined in a single three position valve or the valve 42A may comprise a relief valve in its 'blocking' position. <IMAGE>

Title: Method of redrawing a flanged cup
Inventor: KOBAYASHI TOMOMI
IPC: B21D51/26
Filed: 1990-11-13
Abstract: In the redrawing method, a flange-correcting die 16, arranged coaxially with and spaced a small distance from a blank holder 5, engages a residual flange 4 of a preliminarily drawn cup 1 before the flange is introduced into a clearance between the blank holder 5 and a redrawing die 6. The flange-correcting die has a working face, the inner diameter of which is gradually decreased; the distance from the peripheral face of the cup on the tangential line of the working face to the point of the contact with the working face is substantially constant at least in the introduction side portion of the working face. According to this redrawing method, a draw-redraw-formed can having an excellent shape or dimensional precision can be obtained without occurence of troubles such as edge breaking of the material, breaking of the coating and formation of an enamel hair. <IMAGE>

Title: A receiving antenna array with adaptive beam forming through computing
Inventor: DESODT GUY
IPC: H01Q3/26
Filed: 1990-12-06
Abstract: The invention consists in deriving the complex weighting coefficients assigned to the signals from the various elemental antennas of the array before their summation for forming the received signals, from a system of equations defined by a matrix relationship (see page 1, line 28). The matrix relationship involves a matrix resulting from the weighted summation of the covariance matrix of the signals delivered by the various elemental antennas of the array in response to real noise and a covariance matrix of the signals delivered by the various elemental antennas of the array in response to a nonisotropic false noise. The false noise represents a set of false jammers which reduce sidelobes in the antenna response which might arise in the absence of real jamming i.e. when adaptivity is non-operational. The resulting response contour is also chosen to avoid disturbing the main lobe direction.

Title: Junk mill
Inventor: GILBERT HORACE EDWARD
IPC: E21B10/32
Filed: 1991-03-21
Abstract: The mill has a body (3) with a lower end having approximately sectorially shaped lands, the lands being dressed with tungsten carbide (5). An enlarged internal diameter bore of the body is provided with a reciprocal fluid driven piston (20), the piston being sealingly engaged to the internal bore and biassed away from the lands by a compression spring (30). interspaced between each of the lands is a pivotal arm (40) having a pivotal axis perpendicular to the body longitudinal axis, each arm having at least a lower end portion dressed with tungsten carbide, the lower end of each arm being substantially in the same plane as that of the dressed lands. The piston is arranged to be driven by fluid pressure toward the arms to rotate the arms radially outwardly so that the arms may expand the cutting surface of the mill. The junk mill is therefore afforded the capability of being radially expanded. <IMAGE>

Abstract: Under-soil heating apparatus comprises a header flow pipe (2), a header return pipe (4), and a plurality of heating flow pipes (6) connected to the header flow pipe and a plurality of heating return pipes (8) connected to the header return pipe (4) running beneath a pitch. At each connection of a heating flow pipe (6) to the header flow pipe (2), and preferably also at each connection of a heating return pipe (8) to the header return pipe (4), there is a valve (16) for controlling the flow rate through each heating pipe (6, 8). The arrangement enables uniform heating of the whole playing surface of the pitch. The heating pipes (6, 8) are suitably buried in trenches (18, figure 3) at a depth, for example 350mm, deep enough to prevent damage to the pipes during normal ground maintenance. So that sufficient heat may permeate upwards to the surface (24), each buried pipe (6, 8) is covered with a layer of pea gravel (20) and a further layer of silica sand (22). <IMAGE>

Title: Nonvolatile semiconductor memory
Inventor: KIM JIN-KI
IPC: G11C16/04
Filed: 1992-05-01
Abstract: A nonvolatile semiconductor memory particularly relates to an EEPROM having NAND-structured cells, and an optimizing programming method thereof. The device includes a memory cell array arranged as a matrix having NAND cells formed by a plurality of serially connected memory cells each of which is formed by stacking a charge storage layer and a control gate on a semiconductor substrate, and enables electrical erasing by the mutual exchange of a charge between the charge storage layer and the substrate, a data latch circuit LT, a high voltage supply circuit HV, a current source circuit CS, a program checking circuit PC, and a program status detecting circuit PS. The programming state is optimized while being unaffected by the variance of process parameters, over-programming is prevented by the use of a verifying potential, and the performance of the chip is enhanced by automatically optimizing the programming with a chip's internal verification function. External control is not required, which enhances performance of the overall system. Also, a page buffer PB of an existing flash memory having a page mode function is employed, which is applicable to currently used products. <IMAGE>
