Abstract: A pyrazolecarboxamide derivative represented by the formula hereinbelow is useful since it has preventively, curatively or systematically controlling effects against various plant diseases and fungicides containing said compound as an active ingredient have excellent controlling activities: ##STR1## wherein R.sup.1 and R.sup.2 which are identical or different and represent each a hydrogen atom, a halogen atom, a methyl group, an ethyl group or a trifluoromethyl group, R.sup.3 represents a hydrogen atom or a methyl group and n represents 0 or 1.

Abstract: A current driving circuit including a CMOS inverter, a Darlington amplifier, and a semiconductor switch, enables a printing head to be operated with low power consumption. The Darlington amplifier having a plurality of bipolar transistors is connected to an output part of the CMOS inverter. The semiconductor switch, which is connected to the Darlington amplifier, controls the bias voltage of the Darlington amplifier in synchronism with an input signal inputted to the CMOS inverter.

Abstract: A die for extruding honeycomb structural bodies includes a plurality of ceramic batch exhaust grooves and a plurality of ceramic batch supply apertures. Tubes are fitted in at least some of the ceramic batch supply apertures to improve or make constant the surface roughness and dimensions of inner surfaces of ceramic batch supply apertures through which the ceramic batch passes, thereby producing perfect ceramic honeycomb stuctural bodies. The adjustment of flow of ceramic batch is so simplified that any other controlling plate which would be required in the prior art is not needed for controlling the flow. When the supply apertures have been worn off, the tubes are exchanged by new ones to restore the required inner surfaces easily.

Abstract: 3,4-Disubstituted benzoxa(thia)zole-2-one derivatives of the formula; ##STR1## wherein R.sub.1 is a halogen atom or methyl group, R.sub.2 is a methyl or ethyl group and X and Y are individually an oxygen or sulfur atom, and their preparation and use as a fungicide.

Abstract: Carrier particles are disclosed for use in a two-component dry-type developer for developing latent electrostatic images to visible images, for use in electrophotography, electrostatic recording methods and electrostatic printing methods, which carrier particles are coated with a silicone resin coating layer having high resistance to abrasion and the so-called "spent phenomenon" while in use, and which therefore can be used repeatedly for a long period of time, yielding developed images with high quality. The high resistance to abrasion of the silicone resin coating layer is attained by adding to the silicone coating layer, as an inorganic fortifying agent against abrasion, silicon carbide or potassium titanate.

Abstract: A two-component dry-type developer which comprises carrier particles coated with silicone resin and toner particles containing as a negative polarity control agent a monoazo metal complex dye. As the monoazo metal complex dye, the following metal complex dye is preferable for use in this two-component dry-type developer: ##STR1## wherein X, Y and Z independently represent hydrogen, halogen, a carboxyl group, a hydroxyl group, a nitro group, a sulfo group or a sulfonamide group; and A.sup.+ represents H.sup.+, K.sup.+, Na.sup.+ or an aliphatic ammonium cation.

Abstract: A fungicidal indanylbenzamide derivative of the formula: ##STR1## wherein X is a lower alkyl, nitro, or trifluoromethyl group or a halogen atom, and R.sub.1, R.sub.2 and R.sub.3, which are same or different, each represents a hydrogen atom or a lower alkyl group.

Abstract: A system for detecting whether a machine is in the normal or abnormal state by comparing detected values of waveforms of signals such as vibration generated from the machine with a set value a plurality of times to indicate failure of the machine when the detected values reach the set value a predetermined number of times.

Abstract: 3,4-Disubstituted benzoxa(thia)zole-2-one derivatives of the formula: ##STR1## wherein R.sub.1 is a halogen atom or methyl group, R.sub.2 is a methyl or ethyl group and X and Y are individually an oxygen or sulfur atom, and their preparation and use as a fungicide.

Abstract: A fungicidal composition which comprises as an active ingredient a 1,8-disubstituted carbostyril derivative of the formula: ##STR1## wherein R is a chlorine, bromine or fluorine atom or methyl group, A is an ethylene or vinylene group and X is an oxygen or sulfur atom, and an inert carrier or diluent.

Abstract: Three primary color toner images are transferred successively onto a copy sheet from three photoconductive drums. The copy sheet is successively moved into engagement with the drums in register with the toner images by an endless belt. Various transfer charging means are provided to electrostatically adhere the copy sheet to the belt and counteract an adverse accumulation of charge on the copy sheet caused by accumulation of toner substance thereon during the three successive transfer operations.

Abstract: An agricultural and horticultural microbicidal composition which comprises as an active ingredient a compound represented by the formula: ##STR1## wherein R.sub.1 is a methyl or ethyl group, halogen atom or methoxy group and R.sub.2 is a methyl or ethyl group, and an inert carrier, which shows high microbicidal activities against phyto-pathogenic microorganisms without any material toxicity to mammals, fishes and crops.
