Abstract: A mining riser pipe is extended from above water toward a water bottom containing water bottom resources, and a lower portion of an insertion pipe connected to a lower portion of the mining riser pipe is inserted into the water bottom. A liquid is supplied into the insertion pipe and a rotation shaft extends axially inside both of pipes is rotated to rotate stirring blades attached to a lower portion of the rotation shaft inside the insertion pipe, thereby drilling and dissolving mud S inside the insertion pipe into a slurry form is raised to an upper portion of the insertion pipe by a stirring flow generated by the rotation of the stirring blades, and the raised mud is lifted above the water through the mining riser pipe by lifting force.

Abstract: In an absorbent part of an absorbent product, super absorbent materials located between two sheets in an absorbent area swell by absorption of moisture of excrement, and spaces extending in a longitudinal direction from an opening, which is formed at a portion of upper absorbent layer facing the crotch region of a wearer, are formed between a non-absorbent area where the super absorbent materials do not exist and the upper absorbent layer and between the non-absorbent area and a lower absorbent layer. In the absorbent product, through the spaces, moisture of excrement in the second excretion and later can be quickly diffused over a wide area along the longitudinal direction of the absorbent part, and the moisture of excrement can be absorbed in a wide area of the absorbent part. As a result, it is possible to maintain high absorbing ability in multiple excretions in the absorbent product.

Abstract: A disposable urine absorbent product has a sheet-like main body part having an approximately rectangular shape, and an elastic member which lies from one side end of the main body part to the other side end through a front end. In the disposable urine absorbent product, the elastic member which is bonded to the main body part in the state where the elastic member is stretched contracts at left and right sides and a front side of an absorbent core, and therefore, the pair of side ends and the front end in the main body part stand upward at periphery of a front part of the absorbent core and a pocket to house the tip of penis of wearer is formed on the front part of the absorbent core by itself. As above, it is possible to cover the male genitalia with simple structure in the disposable urine absorbent product.

Abstract: An electron multiplication gain calibration mechanism, which is capable of readily stabilizing a gain of an electron multiplying CCD image pickup device, is provided. The mechanism comprises a gain adjusting section and a control section. The gain adjusting section is provided independently of gain adjustment by the electron multiplying CCD image pickup device, and sets a reference gain. The control section calibrates the gate voltage for obtaining a desired electron multiplication gain by comparing a video level amplified by the electron multiplication gain to a video level amplified by the reference gain. The control section sets an initial value of the gate voltage, which is supposed to provide the electron multiplication gain equal to the reference gain, and controls the gate voltage gradually so that the video level amplified by the electron multiplication gain becomes equal to the video level amplified by reference gain.

Abstract: A fastening tape comprising a tab part formed at one end of a tape substrate, a fixing part formed at the other end of the tape substrate so as to be attached to a disposable diaper main body, a fastening part formed between the tab part and the fixing part, wherein an attachment is fixed to one surface of the tape substrate at the fastening part, the fastening part is folded at a boundary between the fastening part and the fixing part to form a first fold so that the attachment is inside the first fold, the attachment is joined to the fixing part of the tape substrate, the tab part is folded at a boundary between the tab part and the fastening part to form a second fold so that the attachment is outside the second fold. According to the fastening tape of the above, the tab part of the fastening tape is easily pinched and less likely to be joined to the attachment by folding the tab part, and hence handleability of the fastening tape is improved.

Abstract: Medium members such as thread are provided between woven fabric sheet such as warp knitting serving as the other sheet and base member, forming linear raised portions in the woven fabric sheet. The density of woven fabric sheet at the inclined portions to either side of these raised portions becomes coarse and the gaps between fine filaments on the woven fabric sheet spread, so that retaining heads of one sheet can easily enter and so that the fine filaments easily become hooked to the base portion of the retaining heads. Consequently, the retaining of the one sheet and the other sheet in strengthened, and the peeling strength is improved.

Abstract: In an image pick-up device, a document, picture, OHP (Over Head Projector) film or similar subject is laid on a stage. While the subject is illuminated by a light source unit, the resulting imagewise reflection from the subject is picked up by a television camera and transformed to a video signal. The image represented by the video signal appears on a screen in a conference room or on the individual monitor in a communication conference. Light issuing from the light source unit and offensive to the eye is prevented from leaking to the outside of the device. This, coupled with the fact that irregularity in the illumination on the subject is reduced, insures a clear-cut image. Further, the device is easy to operate and protects the working environment from deterioration due to heat generated by the light source unit.

Abstract: A high sensitivity television camera utilizing storage time control system improves the sensitivity without degradation of resolution. Storage time of signal charge in a CCD image pick-up element which is scanned progressively is controlled. An amount of signal charge stored during the storage time is read out and stored in a pair of frame memories alternately as frame data. A pair of data of adjacent lines stored in the frame memory are read out and delayed by shift registers by 1 clock. Image data are produced from the vertically and horizontally adjacent four pixels which are delayed data and non-delayed data. The image data have a configuration corresponding to the interlace scan.

Abstract: A CCD area image sensor includes, on a single semiconductor chip, a matrix of imaging elements, a plurality of vertical shift registers formed in parallel with rows of the matrix, a first horizontal shift register formed on one side of the matrix, a plurality of lines of CCD memories formed on another side of the matrix opposite to the one side, a second horizontal shift register formed on the same side of the matrix as the lines of CCD memories and first and second charge detectors formed at ends of the first and second horizontal shift registers. The method for operating the CCD area image sensor to produce signals with interlace and line sequential scannings is also described.

Abstract: A solid state imaging device compatible with first and second television systems having different scanning line numbers and different aspect ratios includes a first imaging area and a second area. The number of picture elements in the first area can correspond to the scanning line number of the first system and the number of picture elements in the second area can correspond to the difference in scanning line numbers of the two systems. When using the imaging device with the first system, signal charges in the picture elements in the first area are read out at a first rate while the signal charges in the second area are read out at a second greater rate.

Abstract: A solid state imaging device compatible with first and second television systems having different scanning line numbers and different aspect ratios includes a first imaging area having a number of picture elements corresponding to the scanning line number of the first system and a second sub-area having a number of picture elements corresponding to the difference in scanning line numbers of the two systems. When using the imaging device with the first system, signal charges in the picture elements in the first area are read out in a predetermined period while the signal charges in the sub-area are eliminated in a second predetermined period. When using the imaging device with the second system, a lens imaging device converts the aspect ratio of the second system to the aspect ratio of the first system.
