Abstract: A parallel driving device that drives parallel-connected semiconductor elements includes a control unit and a gate driving circuit. The control unit detects a temperature difference between the semiconductor elements on the basis of detected values by temperature sensors that detect temperatures of the individual semiconductor elements. The control unit generates a control signal for changing the timing at which to turn on a first semiconductor element specified from the semiconductor elements on the basis of the temperature difference. The gate driving circuit generates a first driving signal for driving the semiconductor elements, and generates a second driving signal that is the first driving signal delayed on the basis of the control signal, and applies the second driving signal to the first semiconductor element.

Abstract: It is an object to acquire a program creating device for a programmable controller which is able to create a sequence program without grasping a procedure of an address of an individual parameter area allocated to an object module when a setting of parameters of various functional modules for the programmable controller is executed. The device constitutes setting information creating means 12 for preparing module setting information of a parameter type for the programmable controller by using specific information which is included a functional module, analysis and conversion means 14 for creating a source file to be converted into a sequence program which programmed an operation of the programmable controller according to an analysis of a parameter of the module setting information, and program converting and inserting means 31 for converting a file created by the analysis and conversion means into the sequence program.

Abstract: A right-of-use database stores one or more rights of use of merchandise. Also provided are a unit permitting merchandise to be used when it is determined by referring to the right-of-use database that a right of use is obtained, and prohibiting the merchandise from use when it is determined that there is no right of use or the right of use has expired, and a unit performing a job using the merchandise when using the merchandise is permitted, and decreasing an amount of use from the right of use stored in the right-of-use database.

Abstract: A valve-operation control system for an internal combustion engine includes a timing transmitting device for transmitting the rotational power of a crankshaft at a speed reduction ratio of 1/4 to a cam shaft, and intake-side and exhaust-side valve operating devices.

Abstract: A valve operating device for use in an internal combustion engine for varying operating characteristics of a pair of engine valves (20) in multi-stages depending upon operating conditions of the engine. A cam shaft (31) is provided with a high-speed cam (32), a pair of medium-speed cams disposed on opposite sides of the high-speed cam (32), and a pair of low-speed cams (34) disposed between the medium-speed cams (33) and the high-speed cam (32). A rocker shaft (35) is provided with a first free rocker arm (36) in sliding contact with the high-speed cam (32), a pair of driving rocker arms (37) operatively connected to the pair of engine valves (20), respectively, and in sliding contact with the low-speed cams (34), and a pair of second free rocker arms (38) disposed with the driving rocker arms (37) interposed between the second free rocker arms (38) and the first free rocker arm (36) to be in sliding contact with the medium-speed cams (33).
