摘要:
A winding shaft, for use in a printer, which allows a wound recording paper to be easily removed therefrom. The winding shaft includes a shaft main body, a winding portion and a support-removing member. The winding portion, which sandwiches the shaft main body, winds the recording paper therearound. The shaft main body includes a pair of support-removing members, which respectively project from the shaft main body. The two support-removing members are respectively supported on the two side portions of the shaft main body in such a manner that they can be freely rotated about their respective support shafts. A tension-coiled spring is bridgingly disposed between the two support-removing members, so that the two support-removing members remain in standing positions when no external force is applied to them. If the recording paper is lightly rotated in a direction opposite to the winding direction of the recording paper, then the two support-removing members are brought down in the same direction due to an external force applied thereto from the innermost peripheral recording paper. As a result, the innermost peripheral recording paper is loosened, that is, is caused to float loosely from the outer peripheral surface of the shaft main body, thereby enabling the removable of the recording paper from the winding shaft.

A recording medium feed mechanism for a printer includes first, second and third transport sections in the printer along a medium pathway wherein the first transport section is disposed at the insertion point of the recording medium into the printer, the second transport section is disposed immediately before the printer section relative to the direction of transport of the recording medium and the third transport section is disposed immediately after the printer section relative to the direction of transport of the recording medium. A single drive source is adapted for driving in common drive rollers at all three transport sections. First, second and third opening/closing mechanisms are incorporated respectively at the first, second and third transport sections to provide closure and medium engagement and its transport when the medium is present at a particular transport section and to provide its opening when the medium is not present or no longer present at a particular transport section. A method of control is provided for determining when a recording medium is present or absent from a particular transport section utilizing a recording medium stop member and detector in the medium pathway from which the location of the leading or trailing edges of the recording medium can be ascertained. Enhancement in accurate control is achieved in medium transport permitting the extension of data printing in medium margins adjacent the leading and trailing edges of the medium.

In a pump driver for selectively driving a plurality of pumps, a sun gear is rotated by a single drive source. A planetary gear is meshed with the sun gear. A planetary carrier rotatably supports the planetary gear revolvably around the sun gear. A plurality of driving gears are arranged in a one-by-one manner with respect to the pumps such that the planetary gear meshes with one of the driving gears to selectively drive one of the pumps. A revolution limiter allows a revolution of the planetary gear in a first direction and restricts a revolution of the planetary gear in a second direction opposite to the first direction at a position where the planetary gear meshes with one of the driving gears.

There is disclosed a pharmaceutical composition for inhibiting platelet aggregation comprising 5-(2-chlorobenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine or a pharmaceutically acceptable salt thereof and a 1,5-benzothiazepine derivative of the formula: ##STR1## wherein R.sup.1 is a lower alkyl group or a lower alkoxy group, R.sup.2 is a lower alkanoyl group, R.sup.3 and R.sup.4 are a lower alkyl group and R.sup.5 is hydrogen atom, a lower alkyl group or a halogen atom, or a pharmaceutically acceptable salt thereof.
摘要:
A method for operating a converter on the basis of a direct observation of the slag-forming conditions in a vessel interior.A device for observing the vessel-interior light is disposed in a throughhole extending through the side wall of a top-blowing or top- and bottom-blowing converter to reach the vessel interior. The converter operation can be carried out at a high accuracy of the slag-amount control on the basis of this observation.

A magnetic phase shifter control system comprises a magnetic phase shifter for producing an output signal in accordance with a control command at a predetermined amplification degree, a circuit for suppressing the output signal of the magnetic phase shifter to a level lower than a predetermined level on command, and a circuit for reducing the amplification degree of the magnetic phase shifter when the suppressing circuit is operative, whereby a delay for response due to a dead time which the magnetic phase shifter inherently has is eliminated.

Regenerative brake control system for DC motor, in which a resistor is inserted in the motor circuit to effect regenerative brake control from a high speed by use of a chopper. In the voltage control region where the motor voltage less the voltage drop across the inserted resistor is controlled below an equivalent source voltage, the inserted resistor is not short-circuited, thus improving the efficiency of the regenerative brake.
