Title: Rotary hoe cultivator
IPC: A01B33/02
Filed: 1922-01-11
Abstract: 197,989. Howard, A. C. Jan. 11, 1922. Rotary-tool cultivators; lifting tool-frames manually.-In a rotary-hoe cultivator which may comprise one or more cultivator units, pivoted supports for the units, driving gearing mounted on the supports, and means for hitting the cutters and permitting them to rise over obstructions, each cutter blade consists of a strip of steel having a cutting edge on one side and one part of which is adapted to be secured to a rotatable element with its cutting edge sloping backwards while the other part is bent backwards and also longitudinally and transversely in such a way that all the cutting edge will be the same distance from the axis of rotation and will be inclined at the same angle to its circular path. The cultivator units are carried by supports fixed on sleeves 12 rotatably mounted in brackets 11 depending from a frame 5. Each unit consists of bent cutter blades 6 arranged as shown and fastened to collars 7 on a sleeve 8 which is driven from a spindle 15, through a dog clutch 17, 18, the spindle being driven from an engine through spur gearing in a casing 16. The two parts of the dog clutch are shaped to allow of relative rocking, and a flange on the part 18 engages with the end collar 7 to form a friction clutch to allow of slipping. Ribs on the flange engage with springs 20. To allow of the units rising over obstruction and of their being adjusted and lifted vertically, arms 64 on the supporting tubes 12 are connected by adjustable and spring-controlled toggle links 65, 66 to arms 67 on a shaft 58 which may be rocked by rotating a screw 60 passing through a rocking bearing 61 and screwing into a tapped sleeve 59. In making a cutter blade 6 the outer part 10 of the steel strip is first bent backwards in its own plane and then bent over laterally and curved as shown in Fig. 9 so that the front and rear edges form circular arcs struck from the same centre 101 with different radii, and the angle of inclination of the part 10 is the same along the whole length of the cutting edge.

Abstract: PCT No. PCT/EP87/00494 Sec. 371 Date Apr. 29, 1988 Sec. 102(e) Date Apr. 29, 1988 PCT Filed Sep. 2, 1987 PCT Pub. No. WO88/01807 PCT Pub. Date Mar. 10, 1988.A circuit arrangement for electronically commutating a multi-phase direct-current motor, in which a predetermined number of markers are distributed around the circumference of the rotor. A sensor detects the markers and generates corresponding commutating pulses to activate the phase windings of the motor. The commutating pulses advance a counter which has a plurality of outputs. These outputs control switches that connect the phase windings alternately to an operating voltage and to a reference voltage. The counter resets itself to zero after receiving a predetermined number of commutating pulses that is a whole-number divisor of the number of markers. A special marker is provided for resetting the counter from the outside, so that the stator applies a torque to the rotor which is always optimum and phase displacement is prevented.

Title: Microapertured polymeric web exhibiting soft & silky tactile impression
Inventor: CURRO JOHN JOSEPH
IPC: B29C51/22
Filed: 1992-08-06
Abstract: §) A microapertured polymeric web exhibiting a substantially uniform soft and silky tactile impression on at least one of its surfaces. In a preferred embodiment the present invention relates to webs exhibiting a fine scale pattern of discrete surface aberrations, each of said surface aperrations having its amplitude oriented substantially perpendicular to the surface in which said surface aberration originates. At least one tiny aperture (microaperture) is provided substantially coincidental with the maximum amplitude of each surface aberration. The discontinuity created by the aperture at the peak of each of the surface aberrations substantially reduces the resistance to both compression and shear of each individual surface aberration. In addition the volcano-like edges formed at the periphery of each microaperture are typically in the form of thin, irregularly shaped petals which not only reduce the total contact area with the user's skin, but which are also easily deflected when re'ative movement with the user's skin occurs. Microapertured webs of the present invention are also relatively quiet when subjected to movement, making them particularly suitable for use as topsheets and/or backsheets in disposable absorbent structures such as adult incontinent briefs.

Title: Semiconductor device
Inventor: HORIUCHI SHIGENORI
IPC: H01L27/04
Filed: 1985-01-07
Abstract: PURPOSE:To increase latch-up withstanding voltage by forming a reverse conduction type diffusion resistor and a well layer onto one conduction type semiconductor substrate, shaping one conduction type diffusion resistance layer to the well layer, changing the order of these diffusion resistors in response to power supply systems used, connecting these diffusion resistors in series and employing them as protective resistors. CONSTITUTION:A diffusion resistance layer 2 having a P-type as a reverse conduction type and a P-type well layer 3 are formed to the main surface of a substrate 1 in a row. A diffusion resistance layer 7 having an N-type as one conduction type is shaped into the well layer 3. The P-type diffusion resistor 2 and the N-type diffusion resistor 7 are connected in series, and a negative power supply (such as -5V) is inputted to the P-type diffusion resistor side, and outputted to a circuit on the outside of the figure from the N-type diffusion resistor 7 side. Consequently, the voltage of the negative power supply at -5V is dropped slightly by the P-type diffusion resistor 2 first, and to some extent dropped by the N-type diffusion resistor 7 and outputted. Accordingly, the diffusion resistors having one conduction type and the reverse conduction type are connected in series, and the order of the connection is changed in response to power supply systems and the diffusion resistors are connected, thus bringing a parasitic transistor shaped between the substrate 1 and the well layer 3 to a reverse bias state, then turning a parasitic thyristor OFF, provided that the generation of a latch-up can be prevented.

Title: Sodium-sulfur battery
Inventor: SATO YOSHIMI
IPC: H01M2/08
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To increase the length of a corrosion object interface, to convert the operating direction of the stress and to reduce it, and to improve the sodium corrosion life, by providing a recess part or a convex part at the heat pressure contact part of a negative electrode container flange and an insulator, at the insulator side. SOLUTION: In a sodium-sulfur battery, and when a negative electrode container flange 2 and an insulator 1 are heat pressure connected through an intermediate member 3, a recess 12 is provided at the insulator 1 side. The boundary between the intermediate member 3 and the insulator 1 is an objective boundary to generate a corrosion by the sodium of a negative electrode material 11. But by the recess 12 at the insulator 1 side, the distance of the corrosion objective boundary is increased so as to improve the corrosion life. When a corrosing crack generated from the inner end of the interface is progressed to the recess 12, its route is converted in the inner direction of the insulator 1, and as a result, the crack opening is suppressed to convert the direction of the stress, and its size is also reduced.  Consequently, the corrosion speed is reduced so as to improve the corrosion life. The same effect can be obtained by providing a convex part at the insulator 1 side instead of the recess 12.

Abstract: PROBLEM TO BE SOLVED: To service an optimum car by forming a predicted traffic flow by using a predicting means, computing hall call probability in every floor and direction in the near future from the predicted traffic flow and applying genic algorism to the assignment of the car based on this value. SOLUTION: We are in a state where predicted hall call probability in every floor and direction is already computed, a hall call in the rising direction of a ninth floor is already assigned to a second car, a hall call in the lowering direction of a fifth floor is already assigned to a fourth car, a first car is in the middle of travelling toward an eleventh floor by a call from the car inside and a third car is in a stopped state.  When a hall call is generated in the rising direction at the first floor, it is possible to assign a car judged most favourable in answers capable of being composed in such a way as to specify the first car for an unassigned hall call in the rising direction of the first floor and the fourth car for a predicted hall call in the rising direction of a second floor by converting the answer into a genic form and using genic information for example '143123422240023342313443' of an individual (a).
