Abstract:
A method for producing crystalline complex perovskite compounds from starting compounds of at least one metal such as Ca, Ba or Sr, at least one metal such as Mg, Zn, Ni or Co and at least one metal such as Ta or Ni. The respective compounds are selected from oxides, hydroxides, hydrous oxides, and water-soluble organic compounds and inorganic salts of the respective metals. The water-soluble organic compounds and inorganic salts are capable of yielding metal oxides, hydroxides and hydrous oxides by hydrolysis. These starting compounds are heated at certain temperatures in an alkaline aqueous solution to obtain the perovskite compound at significantly low reaction temperatures of at least 95.degree. C. Prior to the heating, the starting compounds may be treated in the alkaline aqueous solution at temperatures lower than 95.degree. C. to form a uniformly mixed amorphous phase of the compounds and then heated.
Abstract:
Electrostatic charge on a cassette or disc is grounded, when the latter is inserted into a player therefor through an opening formed in a front panel thereof, through a grounding path connecting a hinge pin of a flap covering the opening normally by a biasing spring associated therewith to a chassis of the player.
Abstract:
Heavy duty pneumatic tires having lug grooves at a tire tread surface are disclosed, wherein a width of a tread portion from a tire equator to one of tread edges which tread portion is to be located on a wheel-mounted outer side is larger than that of the other tread portion from the equator to the other tread edge. When contours of the tread portions located on the opposite sides of the tire equator are approximated by two respective circular arcs, the radius of curvature of the wider tread portion is larger than that of the narrower tread portion. A depth of grooves at the shoulder portion on the wider tread portion which depth is expressed by a distance between the tread edge and the bottom of the lug grooves is made smaller than that of the narrower tread portion.
Abstract:
Lead frame for mounting a semiconductor chip and improving the packing density of devices such as a plastic chip carrier type IC is disclosed. A portion of inner leads, located parallel to the chip stage and the edge of a molded case is made as thin as possible and held by inner lead supporting bars to tie bars until the molding process is finished. After molding process is finished, these bars supporting the leads and stage are cut away. Packing density is improved an amount ranging from 20% to 30%.
Abstract:
A magnetic tape reproducing apparatus comprises a tape guide drum spirally wrapped with a magnetic tape on an outer peripheral surface thereof, a first mechanism for pivotally supporting the drum, and second mechanism for varying the inclination angle of the drum in a special reproduction mode of the reproducing apparatus, which special reproduction mode is a reproduction mode in which the tape moves with a tape moving speed and/or a tape moving direction different from a tape moving speed and/or a tape moving direction in a normal reproduction mode (or recording mode). The second mechanism varies the inclination angle of the drum in the special reproduction mode in one of two mutually opposite directions with respect to a reference inclination angle of the drum at the time of the normal reproduction mode. The second mechanism varies the inclination angle of the drum depending on the tape moving speed and direction of the tape in the special reproduction mode so that an inclination angle of scanning loci of rotary video heads with respect to the tape longitudinal direction becomes equal to an inclination angle of video tracks on the tape with respect to the tape longitudinal direction.
Abstract:
A magnetic tape recording and reproducing apparatus includes a rotatable head drum having heads and inclined with respect to a reference plane, and a pair of movable guide poles movably located in first positions respectively upstream and downstream of the head drum in a direction of travel of a magnetic tape, for guiding the magnetic tape to be wrapped helically around the head drum in a wrapping range along a tape path inclined with respect to the reference plane to allow each of the heads to scan the magnetic tape along a scanning locus to form thereon a track inclined with respect to a longitudinal direction of the magnetic tape in a recording mode at a normal speed. In a fast-forward or fast-reverse playback mode, one of the tape guide poles is displaced along the reference plane and locked in a second position other than the first positions to change the wrapping range of the magnetic tape. The tape path is shifted so that the formed track on the magnetic tape will be brought into conformity with the scanning locus of each of the heads when the magnetic tape is transported at a higher speed in the playback mode.
Abstract:
A standard member for automatically, stably, and highly accurately performing magnification calibration used in an electron microscope, the standard member including, on the same plane, a multilayer film cross section formed by alternately laminating materials different from each other, a plurality of first mark patterns arranged across a first silicon layer and in parallel to the multilayer film cross section, at least a pair of second mark patterns arranged across a second silicon layer thicker than the first silicon layer on the opposite side of the first mark patterns with respect to the multilayer film cross section and in parallel to the multilayer film cross section, and a silicon layer arranged on the outer side of the first mark patterns and the second mark patterns with respect to the multilayer film cross section.
Abstract:
A printer includes a first receiving unit that receives a print job containing a printing requirement, where the printing requirement is set as either an indispensable requirement that is indispensable for executing the print job or a desired requirement that is desirable for executing the print job; a second receiving unit that receives, from each of external image forming apparatuses connected to the image forming apparatus via a network, a printability level indicating whether the external image forming apparatus has a printing function satisfying the indispensable requirement or a printing function satisfying the desired requirement; a selecting unit that selects an image forming apparatus that executes the print job from the external image forming apparatuses by checking the printability level; and a print-operation control unit that sends the print job to the selected image forming apparatus and causes the selected image forming apparatus to execute the print job.
