Abstract: A sheet receiving and stacking apparatus is formed of a base table with a stacking section for stacking a rectangular sheet, and guide members for receiving the rectangular sheet and for guiding the rectangular sheet to the stacking section of the base table. The guide members have at least one movable member which protrudes out on the stacking section side of the base table. The movable member receives the side edge of the rectangular sheet floating downwardly, retreats to the outside of the stacking section with the weight of the rectangular sheet, and is movable to protrude again towards the stacking section side when freed from the weight of the rectangular sheet.

Abstract: In a rotary stencil printer in which a back press roller 12 is provided with a transverse groove 26 for receiving a transverse bar 16 of a printing drum 10 and a printing sheet applied with a printing at a nipping region 32 between the printing drum and the back press roller is transferred for a while as attached onto the cylindrical outer circumferential surface of the back press roller by a pinch roller or rollers 40 provided at an outlet side of the nipping region so as to press at a side edge portion or portions of the printing sheet against the outer circumferential surface of the back press roller, the position control of the pinch roller or rollers to conform to the sheet width is carried out in a condition that the pinch roller or rollers are aligned with the transverse groove of the back press roller.

Abstract: A toner for electrophotography, which is obtained by attaching fine particles, each of which is formed by coating a core particles, e.g., metal oxide powders, ceramics, inorganic particles or resin particles, with a long-chain fatty acid metal salt to a surface of each of toner particles. The present toner gives an excellent image without causing any phenomenon of white spot within character, and the image formed is free from any fog and black speckle in an image background portion.

Abstract: A compound of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each a lower alkyl group or they may together represent a lower alkylene group so as to form a nitrogen-containing cyclic group with the nitrogen atom to which they attach, R.sub.3 is a cycloalkyl(lower)alkyl group, an oxacycloalkyl(lower)alkyl group or a dioxacycloalkyl(lower)alkyl group and n is an integer of 0 to 2, which is useful as a herbicide.

Abstract: Benzylsulfinyl pyridine-N-oxides represented by the formula: ##STR1## wherein X is a chlorine atom or a bromine atom; and Y and Z, which may be the same or different, are each a chlorine atom or a fluorine atom, is disclosed. A process for producing the same, and a herbicide containing the same as an active ingredient are also disclosed.

Abstract: An apparatus for continuously measuring the flow rate of a fine material flowing through a transport pipe, which comprises: an integrator for integrating calculated values of the flow rate of a fine material flowing through a transport pipe, obtained by a flow rate calculating means; a correction controller, said correction controller being adapted to calculate the total weight of the fine material fed during a prescribed period of time while the fine material in a hopper is only decreasing in amount from said hopper into said transport pipe, on the basis of a measured value of the weight of the fine material in said hopper, and to actuate said integrator during said prescribed period of time; a divider for calculating the correction coefficient "k", i.e.

Abstract: An antenna adapter for television which comprises an input connecting element to be inserted into a plug socket for domestic use, which element is connected to one end of a feeder intermediately with a fuse connected in series, the other end thereof being formed so as to be connectable to the input terminal of the antenna, and a circuit-changing switch or a variable resistance in the midpoint of the feeder for appropriately changing the impedance of the feeder.
