Are disclosed disazo compounds represented by the general formula (1): ##STR1## wherein A represents a phenylene or naphthylene group which may be optionally substituted; each of R.sup.1 and R.sup.2 represent independently a hydrogen atom, an alkyl group or a phenyl group which may be optionally substituted; and m is 1 or 2. The compounds are highly water-soluble and are stable to long term storage. Ink compositions comprising the compounds of the invention can produce a printed image with full depth of shade and are excellent in resistance to water.

A synthetic-aperture sonar system of the present invention includes a range curvature compensating section having a divided aperture propagation time calculation 32. The calculation 32 calculates a round-trip signal propagation time on the basis of a divided aperture for transmission and a divided aperture for reception, thereby calculating a range curvature correction time. A transmission/reception section includes a PRF (Pulse Repetition Frequency) modificator and a divided aperture switch. The PRF modificator adjusts PRF such that a ratio between the aperture length and the divided aperture length of the transducer is an integral multiple. The divided aperture switch 16 switches the outputs of elements on the transducer each being assigned to one of the divided apertures, produces a sum of the outputs of the individual element on each divided-aperture, and feeds the sum to a range compressing section. With this configuration, the system reduces range curvature compensation errors, prevents the transducer from being scaled up, and eases limitations on the number of multi-transmission/reception ascribable to a platform speed.

Novel agent for the treatment of kidney diseases, which comprises as an active ingredient a 2-oxo-imidazolidine compound of the formula: ##STR1## wherein R.sup.1 is a lower alkyl group, R.sup.2 is a lower alkyl group, R.sup.3 is a phenyl-substituted lower alkyl group, and R.sup.4 is hydrogen atom or a lower alkyl group, or a pharmaceutically acceptable salt thereof.
摘要:
An apparatus in which a charger, three developer units and a dryer are mounted on a table reciprocally movable relative to an electrophotographic film for subjecting the film to three cycles of processing each constituting charging, exposing, developing and drying in this recited order so as to produce a color image on the film. The developer units to be operated for the respective cycles are switched by shifting the position of the developer operating means relative to the position of the developer units by the movement of the table. Thereby, a color image can be automatically obtained yet the apparatus is compact and simple in construction.

There is provided a child car seat capable of preventing a seat body from being unintentionally moved to a turning position. The child car seat includes a pedestal and a seat body that can be slid with respect to the pedestal. A plurality of reclining positions and a turning position are included in a range within which the seat body can be slid. The seat body includes a retractable projecting member projecting toward the pedestal, and an operation member connected to the projecting member. The seat body can be held in the respective positions when the projecting member is engaged with the pedestal. An operation amount of the operation member, which is required for sliding the seat body between the reclining positions, is smaller than an operation amount of the operation member, which is required for sliding the seat body from the reclining position to the turning position.

An offset rotary joint unit equipped with a rotation correction mechanism, in which a bending motion can be executed in a two-dimensional plane only by virtue of a rotary mechanism and which can support a high-load weight and is applicable for two-arm mechanisms such as nursing assistant robots. One offset rotary joint unit 4 is composed of a first arm 1, a rotation correction arm 2 rotationally driven around the axial line of the first arm, and a second arm 3 rotationally driven around an axial line obliquely intersecting with the rotation correction arm. A rotation correction joint mechanism 5 linking the first arm 1 and the rotation correction arm 2 and an offset rotary joint mechanism 6 linking the rotation correction arm 2 and the second arm 3 are driven by a single motor 12, and the rotation correction joint mechanism 5 rotates synchronously and in the reverse direction, following the rotation of the offset rotary joint mechanism 6, thereby allowing the second arm 3 to execute a bending motion in a two-dimensional plane with respect to the first arm 1 only by virtue of rotary mechanisms.

A robot is obtained having various functions that are demanded for planetary landing vehicles, extreme operations robots or the like, in particular to provide a leg structure for a robot that is capable of getting up itself when overturned, facilitating take-off and landing on uneven ground, and that has a walking function and that has a hand function capable of three-dimensional operation. A robot comprises a main robot body and at least three legs mounted on this main body for enabling three-dimensional movement of the main robot body such as a self-erecting action or walking action; each leg is constituted by a multi-joint arm having a plurality of said offset rotary joints linked together and has a ground-engaging member mounted at the leading end of the arm, so that each leg is capable of independently controlled three-dimensional movement and drive.

A metal phthalocyanine compound that is useful as a black colorant suitable for use in an ink-jet recording ink, a water-based ink composition containing the metal phthalocyanine compound, and a product colored with the metal phthalocyanine compound. In particular, a metal phthalocyanine compound having, as substituents, both an acylamino group and a carboxyethylamino group on the phthalocyanine structure, or the salt thereof is used as a black colorant. Recorded images formed by the use of this colorant are excellent in light fastness and water fastness and exhibit absorption in infrared and visible regions, so that highly effective utilization can be found in printing of, for example, bar codes which are available in near-infrared ray reading.
摘要:
The present invention provides contact sensors capable of determining the pressure distribution over the whole surface of each of joint units having a cylindrical shape, both end portions of which are cut at an offset angle, and constituting robot arms. In order to provide a technology enabling real-time drive control of the robot arms by using detected values from these sensors, the points of intersection of the electrodes are distributed across the whole surface of each joint by forming a pressure-sensitive sheet sensor in which column electrodes arranged in parallel, and row electrodes arranged in a wound-string shape, are combined, these joints having a cylindrical shape, both end portions of which are cut at an offset angle. In addition, by making an electrode structure that covers a prescribed width in both rows and columns, the number of signal output terminals is reduced and the operation processing load is lightened. Moreover, after executing local processing, through the use of an encoder and pressure-sensitive sheet sensor provided in each of the joints, in addition to the information processing means, [this data] is sent to the CPU, whereby the central operation processing load is lightened.
