Abstract: Here is disclosed a flexible plastic sheet comprising a plurality of first direction ribs (Y.sub.1, Y.sub.2 . . . ) each having opposite sides (12, 13) extending in the first direction (Y) and curved downward crossing a plurality of second direction ribs (X.sub.1, X.sub.2 . . . ) each having opposite sides (14, 15) extending in the second direction (X) and curved downward. The sheet is continuous in an area surrounded by each pair of adjacent first direction ribs and each pair of adjacent second direction ribs which cross the pair of adjacent first direction ribs. At each crossing (C.sub.1, C.sub.2, C.sub.3, C.sub.4), one of the ribs bulges upward and the opposite side edges of this rib are connected to the top of the other rib. The plastic sheet of this invention is featured by less gloss and less sticky touch, and is preferably used as a liquid-impermeable backsheet of a disposable hygienic wearable article.

Abstract: Here is disclosed a flexible and air-permeable plastic sheet comprising a plurality of first direction ribs (Y.sub.1, Y.sub.2, . . . ) each having opposite sides (2, 3) extending in the first direction (Y) and curved downward crossing a plurality of second direction ribs (X.sub.1, X.sub.2, . . . ) each having opposite sides (4, 5) extending in the second direction (X) and curved downward so that each pair of adjacent first direction ribs and each pair of adjacent second direction ribs crossing these first direction ribs define together an air-permeable vacant space. At each crossing (C.sub.1, C.sub.2, C.sub.3, C.sub.4), one of the ribs bulges upward and opposite side edges of this rib crosses the top (T.sub.1, T.sub.2) of the other rib. The plastic sheet of this invention is featured by less gloss and less sticky touch, and preferably used as a topsheet of a disposable hygienic wearable article.

Abstract: A body fluid absorbent article comprising a topsheet formed with tubular liquid passages extending from the bottom surface of the topsheet and an absorbent core, wherein a meshy sheet comprising fibres defining meshes smaller than lower openings of the respective liquid passages is interposed between said topsheet and said absorbent core so that said fibres extend across the lower openings (FIG. 3).

Abstract: A sanitary napkin is provided with flaps including wings formed on laterally opposite sides thereof. Top surfaces of the flaps are formed by liquid barrier sheets of which the inner areas form together with the topsheet pockets therebetween to receive menstrual fluid. The pockets are opened as the wings are folded onto the outer sides of a crotch zone of user's underpants to fix the napkin thereto.

Abstract: To control a flow of body fluid generally occurring on the liquid-permeable topsheet for body fluid absorbent article in a predetermined direction, here is disclosed an improved liquid-permeable topsheet made of thermoplastic synthetic resin comprising a plurality of first direction ribs and a plurality of second direction ribs crossing the first direction ribs so as to a unique rib structure. Tops 7 of the second direction ribs 3 are connected with opposite sides 6 of the respective first direction ribs 2 and each pair of adjacent first direction ribs 2 define a groove 10 serving to guide the body fluid in the predetermined direction.

Abstract: A magnetic head using an MR element and a permanent magnet for applying a bias magnetic field to the MR element, and a lead frame of the head. A sheet of metal is punched or otherwise shaped in a predetermined pattern to produce the lead frame. The lead frame includes sections mounting the MR element and permanent magnet, lead connecting sections electrically connected to connecting sections of the MR element, and tape-contact sections which are flush with a tape-contact surface of the MR element. The lead frame mounted with the MR element and permanent magnet and provided with the lead connecting sections is placed in a metal mold having a predetermined configuration and buried and fixed in place in synthetic resin.

Abstract: Process or producing caustic alkalis or alkali hydroxides by electrolysis, employing a double electrode-type electrolysis tank in which a cation exchange membrane is provided to divide the inside of the tank into cathode and anode compartments, supplying to the anode compartment an alkali chloride, supplying water or a dilute solution of an alkali hydroxide into the cathode compartment, and taking away the alkali hydroxide and the hydrogen gas produced by electrolysis, in a mixed state of gas and liquid from the cathode compartment. The electrolysis tank comprises a number of finger-anodes extending from one of the walls of the tank and a number of finger-like hollow cathodes extending from the other wall of the tank, into which the finger-anodes project to form a gap therebetween, and a cation exchange membrane extending through the gap to divide the inside of the tank into cathode and anode compartments.

Abstract: A coil assembly comprises a plurality of conductive spiral pattern layers which are piled up via (an) insulating layer(s) on a wafer. The electrical connection between the spiral patterns is established by means of a conductive member, which is a portion of the upper spiral pattern layer, filled in a through-hole which is made in the insulating layer so that the spiral patterns are connected in series to develop a high voltage when the coil assembly is moved in a magnetic field.

Abstract: An electrostatic capacitance type pickup stylus for use on an information storage disc comprises a crystal of diamond including a sliding face for slidable contact with the information storage disc, an electrode face supporting thereon a conductive electrode layer for detecting signals on the information storage disc as changes in electrostatic capacitance, a pair of first and second angularly spaced back faces adjoining the electrode face, and a pair of first and second angularly spaced guide faces adjoining each other and the first and second back faces, respectively.

Abstract: A capacitance detection type record stylus comprises a body of artificial diamond having flat faces lying parallel to the crystal planes {111} and {100} wherein adjoining identical crystal planes are either {111} or {100}. A crystal plane {110} is formed between any two of the adjoining identical crystal planes by lapping the edge between them. A conductive material is deposited on the crystal plane {110} to form an electrode for detecting signals recorded as geometric variations on a recording medium. Because of the aligned carbon atoms beneath the crystal plane {110}, a substantial amount of the conductive material penetrates deeply into the diamond making the electrode resistant to wear.

Abstract: A cylindrical diamond body is shaped to form a truncated conical portion. A conductive layer is deposited on the diamond body extending from the truncated end to the other end of the body. The conical portion of the body with the conductive layer being attached thereto is lapped to remove portions of the layer and the diamond body to form a pair of substantially flat surfaces extending from the truncated end toward the opposite end leaving the conductive layer to form a narrow width electrode for picking just one information signal stored in the form of minute pits along a spiral track or concentric tracks.
