Abstract: Novel herbicides are provided. A haloalkylsulfonanilide derivative represented by the formula (1) or an agrochemically acceptable salt thereof: the formula (1): wherein Z is —C(R9)(R10)— or —N(R11)—, A is an oxygen atom, a sulfur atom or —N(R12)—, W is an oxygen atom or a sulfur atom, m is an integer of from 0 to 3, n is an integer of from 0 to 3, m+n is from 1 to 3, R1 is halo C1-C6 alkyl, R2 is a hydrogen atom, C1-C6 alkyl or the like, each of R3 and R4 is independently a hydrogen atom, C1-C6 alkyl or the like, each of R5, R6, R7, R8, R9 and R10 is independently a hydrogen atom, a halogen, C1-C6 alkyl or the like, each of R11 and R12 is a hydrogen atom, C1-C6 alkyl, halo C1-C6 alkyl or the like, and X is independently a hydrogen atom, a halogen, C1-C6 alkyl, or the like.

Abstract: A printing-plate making apparatus is constructed such that a mode selecting switch adapted to change a master supplying process depending on properties of a master X is disposed on a housing 1 of the printing-plate making apparatus and various conditions, e.g., a master supplying process, locking member 4 for a master supplying roller 3, a temperature preset for a panel heater 33 and a compressing force given by press rollers 35a and 35b are automatically changed to optimal conditions corresponding to masters selected by the mode selecting switch. The printing-plate making apparatus is provided with a master heating switch on the housing 1 of the printing-plate making apparatus and when the master heating switch is actuated, applying of a certain voltage to at least a charger is stopped so that the panel heater 33 arranged at a fixing step is kept in the heated state so as to serve as a master heating unit.

Abstract: A thermosetting composition comprising (A) a carboxyl group-containing polyol resin, (B) a hydrolyzable silyl group-containing polymer, and at least one member selected from the group consisting of (C) a dehydrating agent and (D) an alcohol. The composition of the present invention is excellent in the physical properties of the film as well as the storage stability of the coating composition compared to the known compositions containing the curing catalyst.

Abstract: A method of controlling a position of a plate material sheet in a platemaking machine for feeding the plate material sheet in an exposure region and forming a document image on the plate material sheet. A plate material sheet length sensor detects that the plate material sheet to be fed to the exposure region has passed by the sensor. The overall length of the plate material sheet is calculated in accordance with the number of pulses supplied to a plate material sheet drive motor while the plate material sheet length sensor generates an output. Also calculated is a first predetermined number of pulses to be supplied to the plate material sheet drive motor so as to feed the plate material sheet by a first predetermined length within the exposure region.

Abstract: Disclosed is an improved electrophotographic copying machine in which a black frame eliminating mechanism and a random cutting assembly adapted to cut a roll of photosensitive paper to a required length are incorporated. The black frame eliminating mechanism comprises an original supporting window, the length of which is longer than that of an original, an original depressing plate having a white surface facing and covering over the supporting window, means for depositing a charge over the length of a portion of a photosensitive paper, which length corresponds to that of the original, and means for exposing the paper placed at a predetermined position to the light from the entire area of the supporting window.
