The invention relates to a method of and apparatus for agitating and pumping particulate solids which are settled in and beneath a liquid by rotating a vaned impeller which is attached to a pump such that pressure waves are set up in the liquid and the settled solids, the solids being loosened so as to be pumpable, and the agitator being arranged to impart to its surroundings an axial component of...

PURPOSE:To enhance drive frequency without lowering type quality, in an on- demand type ink jet head, by applying plural kinds of drive pulses with different voltage wave forms to an piezo-electric element in a condition synchronous to a type timing signal. CONSTITUTION:By output from an encoder 22 detecting a rotary angle of a carriage moving motor 21, an MPU25 reads out a data from a character g...

Apparatus for automatically laminating photoresist dry film (52) onto each of a plurality of panels (63) stacked upright in a panel feed unit (16) with a 10 DEG slant counterclockwise from the vertical, the film being easily contaminated, limp and tacky, although peelable, thereby enabling the use of a polyethylene protective coating, includes a film feed bar (28) for pulling the film from a roll...

PURPOSE:To make a controlling part changeable which accesses an I/O device in the unit of I/O-instruction by setting a lock control flag and a lock address in an I/O control table, and providing a priority processing function in a scheduler. CONSTITUTION:The lock control flag part 312 in the I/O-control table 31-36 has an area of one byte, and in this area, an 'FF' is set with a 16-ary value at th...

The overall deformation of a tire is measured by using two reference points in different parts of or at least in close proximity to different parts of the rim of the wheel, the reference points are spaced apart in a direction transversely to the plane of rotation of the tire; two transducers are respectively connected to the reference points and to the same particular point on the inside of the ti...

A combinatorial logic circuit with built-in test circuitry for testing function blocks in the circuit is described. The test circuitry comprises apparatus for testing a selected function block in a sequence of function blocks, an apparatus for selectively rendering transparent to a test pattern and test results all function blocks upstream of and downstream from the selected function block and an ...

PURPOSE:To improve the detecting accuracy of runaway by forming a reset signal detecting circuit with a latch circuit, a counter circuit and a comparator and reducing the possibility where the counter circuit is reset by a run-away program. CONSTITUTION:A reset signal detecting circuit 30 consists of a latch circuit 31 which stores the reset data on a watchdog timer, a counter 32 which counts the ...

PURPOSE:To spontaneously remove attached material from surface of a mold for press-forming of a glass material containing lead oxide and to enable continuous forming of lens without influencing the performance of the lens, by varying oxygen concentration of atmospheric gas. CONSTITUTION:A glass material containing lead oxide as a component is heated and pressed with pressing mold to form a lens. I...
