摘要:
An air cleaner includes closure means comprised of a partition wall integrally formed on one side of a filter member, which closure means will selectively shut either a first air-intake port for sucking outside air into a filtration room or a second air-intake port to suck air into the filtration room through an engine room. One of these first and second air-intake ports is selectively closed by a partition wall by turning the positioning of the filter member.
摘要:
A device for indicating the level of liquid contents remaining in a tank which has a viewing portion through which the side of a synthetic resin tank is exposed. The viewing portion is formed around a cap and in the vicinity of an opening of the tank which can be seen through and which is held by a tank holding member, such that the opening of the tank has a dimension which is larger than that of the cap so that the level of the fuel can be viewed through the annular viewing portion formed thereby.
摘要:
An inner mold for molding a cylinder having a bore-forming core for forming a cylinder bore, and a shell core for forming a recess in the cylinder that can serve as, for instance, a scavenging passage. Holes are formed in the bore-forming core for allowing the shell core to fittingly engage with the bore-forming core, and the bottom surfaces of each of the holes are arcuately concaved.
摘要:
A sprocket wheel for driving a saw chain of a chain saw including a pair of annular sprocket wheel members of the same shape and configuration each formed on one side surface thereof with elevated surface portions of a number which is one-half the desired number of the teeth of the sprocket wheel produced as an end product by joining the sprocket wheel members together in such a manner that the one side surfaces thereof having the elevated surface portions face each other.
摘要:
A chain saw including an electromagnetic pump (4) for feeding lubricant to saw chain operative in response to an engine speed sensor (5) for sensing the rpm of an internal combustion engine and a microcomputer (6) for controlling the operation of the electromagnetic pump (4). The microcomputer (6) stores a plurality of lubricant feeding patterns covering the number of actuations of the electromagnetic pump (4), the actuation frequency and the period of time of each actuation so as to control automatically the feeding of lubricant to the saw chain from the electromagnetic pump (4) in response to the engine speed sensor (5) to effect lubricant feeding in conformity with the sawing condition.
摘要:
A photosensitive composition containing the 2-trihalomethyl-5-aryl-1,3,4-oxadiazole compound represented by the following general formula: ##STR1## wherein X represents a chlorine atom or a bromine atom and A represents a phenyl group, a naphthyl group or a phenyl or naphthyl group substituted by a halogen atom, an alkyl group, an alkoxy group, a nitro group, a cyano group or a methylenedioxy group.

Photosensitive compositions containing 2-halomethyl-5-vinyl-1,3,4-oxadiazole compounds represented by the following general formula (I): ##STR1## wherein W represents a substituted or unsubstituted aryl group, X represents a hydrogen atom, an alkyl group or an aryl group, Y represents a fluorine atom, a chlorine atom or a bromine atom, and n represents an integer of 1 to 3.
摘要:
A network control system for packet-transmitting a manipulated variable (MV), calculated from a deviation between a variable from a sensor measuring a physical quantity of a controlled object plant and a set value at a known sampling period, to an actuator provided on the plant side via a network, and causing the actuator to provide the MV to the plant. The system includes: an MV complementing unit that provides a complementary value of the MV to the actuator when an error occurs in a packet transmission; an MV buffering unit that answers back trend data of the MV provided to the plant from the actuator or the complementary value being complemented by the MV compensating unit for the actuator, to the controller via the network; and an MV compensating unit that corrects a calculation of the MV of the controller based on the trend data or the complementary value being answered.
