    摘要: An electrically conductive paste comprises 80% by weight or more of silver powder and 20% by weight or less of a thermosetting resin. The silver powder has a particle size distribution having two peaks at specific positions. Viscosities of the paste measured under a low shearing stress and under a high shearing stress are in respective specific ranges and the ratio of these viscosities is in a specific range. A cured product obtained by heating the paste has a tensile modulus in a specific range. The paste has thermal and electric conductivities approximately the same as those of solder, shows little change in properties under a high temperature and a high humidity or under cyclic cooling and heating, exhibits excellent workability in coating and can be applied to coating by using nozzles having a wide range of diameters. A reliable semiconductor device is prepared by using the paste.

    摘要: It is intended to provide a swash plate type continuously variable transmission capable of automatically affording a lock-up state in which second distributing valves are stopped at their stroke mid-point to cut off motor ports when a motor swash plate stands upright, even without using any special interlocking mechanism. Second distributing valves for bringing motor ports of motor cylinder bores into communication with a high-pressure oil path and a low-pressure oil path selectively in an alternate manner are arranged in parallel with the axis X of a cylinder block; a valve swash plate for reciprocating the second distributing valves is integrally combined with a motor swash plate on the same slant plane; and the motor ports are formed so as to be controlled selectively by the second distributing valves at respective positions 90.degree. out of phase in the circumferential direction of the cylinder block 4 with respect to the corresponding motor cylinder bores, the second distributing valves being stopped at their stroke mid-points when the motor swash plate stands upright. In a swash plate type hydraulic unit for use as a swash plate type oil-hydraulic pump or motor, it is intended to attain the reduction in radial size of the hydraulic unit while ensuring a sufficient plunger stroke.

    摘要: An abnormality of a key component of an electrostatic image-recording machine is detected using a surface potentiometer originally installed in the machine for use in controlling the charging voltage of the photoreceptor drum. The detectable components are: main charger, transfer charger, discharge lamp, and developing roller. They are judged abnormal if the voltage of the drum surface is out of a normal range when they are functioned before an actual recording process (or during warming-up of the machine).

    摘要: In a hydrostatic continuously variable transmission, a pump cylinder of a swashplate type hydraulic pump is integrally and coaxially coupled with a motor cylinder of a swashplate type hydraulic motor. A number of distributor valves are radially arranged for reciprocal movement between radially inner and outer positions to put a large number of pump ports in the hydraulic pump into communication with the higher and lower pressure oil passages, and an eccentric ring circumscribed about the distributor valves is connected to an input member of the hydraulic pump for movement between a clutch OFF position and a clutch ON position. A clutch spring is connected to the eccentric ring for biasing the eccentric ring toward the clutch OFF position, and a weight is added to the eccentric ring and adapted to exhibit a centrifugal force for moving the eccentric ring toward the clutch ON position against a spring force of the clutch spring.

    摘要: A recording apparatus has a printer mechanism for printing images successively on sheets of copying paper, and an image control circuit for delivering image information controllably to the printer mechanism so as to enable the latter to print the images successively. The image control circuit includes a plurality of page memories each for storing image information per single page, a first changeover switch for writing image information selectively into the page memories, and a second changeover switch for reading image information selectively from the page memories. When a sheet of copying paper is jammed in the printer mechanism, a microcomputer system controls the second changeover switch to select a switching mode to read an item of image information out of one of the page memories which stores the item of information to be printed on the jammed sheet of copying paper, for thereby allowing the image to be printed in a shorter period of time after paper jam clearance.

    摘要: A programmable sequence controller which enables display of the contents of a storage means for storing input and output data to and from a machine, and which permits numerical values to be set in the storage device from an external unit. The programmable sequence controller utilizes a sending and receiving unit for an exchange of commands and other data with a numerical control device in order to transfer display content and numerical values which have been set. This allows the contents to be displayed on display means provided in the numerical control device, and permits the setting of numerical values which are entered from a data setting means provided in the numerical control device.
