A printing apparatus comprising a stationary frame structure having accommodated therewithin a plurality of printing hammers arranged in a row, a tiltable support structure positioned in front of the frame structure and rotatable about an axis fixed on the frame structure, a type carrier movable on the support structure partially along a straight travelling path extending in parallel with the row of the printing hammers and forming an elongated clearance between the travelling path and the row of the printing hammers, position retaining means for holding the support structure in an inoperative position having the travelling path of the type carrier spaced wider apart from the row of the printing hammers, clearance adjusting means for minutely adjusting the above mentioned clearance depending upon the thickness of the printing sheet or sheets to be printed at a time, and cam means providing a mechanical and functional intervention between the position retaining and clearance adjusting means.
摘要:
A conference assistance system and method for assisting a user in utilizing conference-related information, each of which: receives input of voice or writing of at least one meeting participant; determines whether text data representing the received voice or writing is to be used by the conference assistance system to generate assistance information, to generate a determination result; when the determination result indicates that the text data is to be used, generates, based on the text data, assistance information for assisting the meeting participant; and controls a display to display the generated assistance information.
摘要:
A gas mixture supplying method includes supplying plural kinds of gases through gas supply lines connected to a common pipeline and supplying a gas mixture of the plural kinds of gases from a gas outlet of the common pipeline to a region where the gas mixture is used through a gas mixture supply line. When two or more gases having different flow rates are supplied simultaneously, a gas having a relatively low flow rate is supplied from one of the gas supply lines provided at a position closer to the gas outlet than that for a gas having a relatively high flow rate.

According to one embodiment, a limpness detecting device includes a transmitting unit to irradiate an acoustic wave towards a conveyed sheet to excite a Lamb wave, a first receiving unit to detect a leaky wave of the Lamb wave emitted from a front surface of the sheet, a second receiving unit to detect a leaky wave of the Lamb wave emitted from a back surface of the sheet, a comparison data calculating unit to calculate comparison data based on the signal detected by the first receiving unit and the signal detected by the second receiving unit, and an intactness judgment unit to compare the comparison data calculated by the comparison data calculating unit with a preset standard value and judge whether the sheet is an intact bill or not, based on a result of the comparison.
摘要:
A stiffness detector transmits acoustic waves to a paper sheet at a predetermined angle to excite Lamb waves. The stiffness detector receives leaky waves of the Lamb waves propagated through the paper sheet at different angles with respect to the paper sheet by a plurality of reception sensors. The stiffness detector is configured to specify a maximum leak angle at which a leak amount of the acoustic waves from the paper sheet becomes maximum based on outputs from the plurality of reception sensors in the reception module and to judge a degree of fatigue of the paper sheet based on the specified maximum leak angle.
摘要:
A riding lawn mower having covers for covering the side part of a cutter deck and the side part of a transmission section. The covers have a plurality of small holes formed in a portion facing the side part of the cutter deck. The accumulation of grass clippings on the upper surface of the cutter deck and the transmission section is reduced, and the state of accumulation of grass clippings is confirmed via the small holes.

A camera system comprising an imaging unit scanned by means of an X-Y address method, horizontal and vertical scanning units for scanning the imaging unit by means of the X-Y address method, a main scanning direction control signal generating unit for generating a main scanning direction control signal for designating a main scanning direction of the imaging unit, a main scanning direction control unit for controlling the horizontal and vertical scanning units so that the main scanning direction coincides with a direction instructed by the main scanning direction control signal, and an output unit for outputting an image signal read in consequence of scanning the imaging unit using the horizontal and vertical scanning units.
摘要:
An exemplary cell library includes a first plurality of types of standard cells. Each of the first plurality of types of standard cells includes threshold voltage adjusting patterns. The upper and the lower boundaries of the threshold voltage adjusting patterns contact the upper and lower boundaries of the cell frame and the distances between the left and right boundaries of the threshold voltage adjusting patterns and the cell frame are set appropriately. Accordingly, it is possible to place standard cells including transistors with different threshold voltages at arbitrary positions without increasing the area of a circuit block or the design cost.
