Abstract:
A disc brake that suppresses braking noises when a vehicle moves backward include an urging spring urging a friction pad toward a rotationally exiting side of a disc when the vehicle moves forward, the urging spring being arranged between a hook portion of the friction pad and a torque receiving portion of a carrier. The urging spring formed through bend of an elastic plate material has its spring constant that is set to be a small value to avoid resonance frequency causing noise where the base end side thereof is fixed to the hook portion of the backing plate while the top end side thereof elastically abuts to the torque receiving portion of the carrier. The urging spring is located at the position that is outside in the radial direction from the center position of the hook portion in its width direction.
Abstract:
A fuel injector includes: a pilot injector configured to spray fuel so as to form a first combustion region in a combustion chamber; and a main injector provided coaxially with the pilot injector so as to surround the pilot injector and configured to supply a fuel-air mixture that is a mixture of the fuel and air to form a second combustion region in the combustion chamber, wherein the pilot injector includes: a center nozzle configured to eject air jet flowing straight in an axial direction on a central axis of the pilot injector; an inside swirler provided on a radially outer side of the center nozzle and configured to cause inflow air to swirl around the central axis; and a pilot fuel injecting portion configured to inject the fuel from between the center nozzle and the inside swirler to air flow in the center nozzle.
Abstract:
A pad spring located at the entrance side in the rotational direction of a disk is provided with guide plate portions, radially urging portions that urge a pair of friction pads radially outward of the disk, and circumferentially urging portions that urge the friction pads in the rotational direction of the disk. Each radially urging portion has a projection bent radially inward of the disk. Each guide plate portion has a space portion that allows the projection to abut against the radially inner wall surface of the associated pad guide when the radially urging portion is displaced radially inward of the disk so as to approach the guide plate portion. The circumferentially urging portions are wide plate-shaped members bent from the guide plate portions.
Abstract:
The present invention provides a toner for electrophotography having a capsule structure including a core and a shell that covers the core, wherein the core contains a colorant, a releasing agent, an amorphous resin, and a block polymer containing a crystalline part and an amorphous part, the weight-average molecular weight of the block polymer is 10,000 or more, the weight-average molecular weight of the resin used in formation of the amorphous part of the block polymer is 1000 to 5000, and the weight-average molecular weight of the resin used in formation of the crystalline part of the block polymer is at least 2 times the weight-average molecular weight of the resin used in formation of the amorphous part of the block polymer, a method of manufacturing the same, a developer for electrophotography including the toner and a carrier, and an image forming method using the developer for electrophotography.

Abstract:
A cold forming tap with an internal finish cutting edge includes an external thread portion having radially outwardly protruding portions and relief portions which are alternately located in a helical direction in which an external thread extends. The protruding portions are forced into a surface of a prepared hole which has been previously formed through a workpiece, for thereby forming an internal thread on the surface. The improvement comprises: at least one of the protruding portions having a root diameter larger than that of the other of the protruding portions, the at least one of the protruding portions being removed down to a root of the external thread, and a flute being formed in a portion corresponding to the root of the at least one of the protruding portions, so as to provide the cutting edge in the portion corresponding to the root.
Abstract:
The present invention provides an amino-acid amide derivative represented by the formula: ##STR1## (wherein R.sup.1 represents a C1.about.C6 alkyl group, a C3.about.C8 cycloalkyl group, or a phenyl group, R.sup.2 represents a hydrogen atom or a methyl group, X represents a halogen atom, a methyl group, a methoxy group, Y represents a C1.about.C6 alkyl group, A represents an oxygen atom, or a sulfur atom, and n represents 0 or an integer from 1 to 3), an agricultural or horticultural fungicide including an effective amount of the same, and a method for killing agriculturally or horticulturally harmful fungi which comprises a step of using a fungicidally effective amount of the amino-acid amide derivative. The present invention provides the amino-acid amide derivatives, which exhibit superior control of plant diseases such as late blight and downy mildew, and which are not harmful chemicals.
Abstract:
The present invention provides an N-sulfonyl carboxylic amide derivative including an N-containing 6-membered aromatic ring represented by formula [I]: ##STR1## wherein R.sup.1 represents an alkyl group, an alkenyl group, or the like, R.sup.2 represents a hydrogen atom, an alkyl group, or the like. R.sup.3 and R.sup.4 represent independently an alkyl group or a nitrogen atom; or the salt of the same, a method for producing the same, and a biocide containing the same as an active ingredient. The N-sulfonyl carboxylic amide derivative including an N-containing 6-membered aromatic ring according to the present invention exhibits superior effects against blight caused by plant pathogenic fungi belonging to Oomycetes such as downy mildew, late blight, or the like in a low concentration as well as controls weeds occurring in paddy fields and plowed fields.
Abstract:
A fungicidal composition for agricultural and horticultural use comprising a suitable carrier and fungicidally effective amount of N-(4-fluorophenyl)-2,3-dichloromaleimide per part of at least 1 compound selected from the group consisting of a compound expressed by the formula: ##STR1## (where M represents manganese or zinc, and when M is manganese, zinc may coordinate in the molecules), N-trichloromethylthio-4-cyclohexene-1,2-dicarboxyimide and 8-oxyquinoline copper. The composition has been found to possess unusually high anti-fungal activity in protecting against various plant disease.
