摘要:
In a generator assembly, outside air, taken from a suction hole into a fixed soundproof housing, is sucked into a portable engine generator covered by a soundproof case to operate an engine and cool the interior of the fixed soundproof housing. The exhaust gas of the engine and the cooling air of the soundproof case are exhausted outside through the exhaust air hole of the soundproof case and the external exhaust hole of the fixed soundproof housing without leaking into the fixed soundproof housing. Therefore, the portable engine generator can be operated while it remains housed within the fixed soundproof housing. The exhaust air duct of the portable engine generator and the communicating duct of the fixed soundproof housing are communicated in a state of close contact, at the time that the portable engine generator has been positioned by a positioning member provided in the fixed soundproof housing. The portable engine generator can be put into or out from the fixed soundproof housing and is guided and housed by wheel guide rails provided within the fixed soundproof housing.

An output circuit for a portable generator having a plurality of output windings provided separately from each other, and control winding provided separately from the output windings. A plurality of thyristor bridge circuits each having thyristors are connected respectively to the output windings. A superposing circuit superposes outputs from the thyristor bridge circuits one upon another to provide a first superposed output voltage. A rectifier circuit is connected to the control winding. The rectifier circuit is disposed such that its output voltage is superposed upon the first superposed output voltage to provide a second superposed output voltage. A control circuit is responsive to the second superposed output voltage for concurrently controlling voltages applied respectively to the gates of the thyristors of the thyristor bridge circuits to thereby maintain the first superposed output voltage at a constant value. An FET is connected to the output of the superposing circuit, and is connectible in series to an external load, for controlling supply of current flowing through the FET to the external load. A current cut-off circuit detects overcurrent in the output circuit and operable, upon detection of the overcurrent, to cause the FET to be turned off to thereby cut off the supply of current to the external load.

A semiconductor substrate eliminates a restriction caused by a width of scribe lines so as to increase a number of semiconductor elements formed on the semiconductor substrate. A plurality of semiconductor element areas are formed by forming a plurality of unit exposed and printed areas, each of which contains the semiconductor element areas. A first scribe line extends between the semiconductor element areas formed within the unit exposed and printed area. A second scribe line extends between the unit exposed and printed areas. A width of the first scribe line is different from a width of the second scribe line.

A Soft Computing (SC) optimizer for designing a Knowledge Base (KB) to be used in a control system for controlling a motorcycle is described. In one embodiment, a simulation model of the motorcycle and rider control is used. In one embodiment, the simulation model includes a feedforward rider model. The SC optimizer includes a fuzzy inference engine based on a Fuzzy Neural Network (FNN). The SC Optimizer provides Fuzzy Inference System (FIS) structure selection, FIS structure optimization method selection, and teaching signal selection and generation. The user selects a fuzzy model, including one or more of: the number of input and/or output variables; the type of fuzzy inference; and the preliminary type of membership functions. A Genetic Algorithm (GA) is used to optimize linguistic variable parameters and the input-output training patterns. A GA is also used to optimize the rule base, using the fuzzy model, optimal linguistic variable parameters, and a teaching signal. The GA produces a near-optimal FNN. The near-optimal FNN can be improved using classical derivative-based optimization procedures. The FIS structure found by the GA is optimized with a fitness function based on a response of the actual plant model of the controlled plant. The SC optimizer produces a robust KB that is typically smaller that the KB produced by prior art methods.

A master slice type semiconductor circuit device including a memory block having at least one memory circuit; one conductive layer provided to peripheral portions of the memory circuit and used as an input portion thereto; power source lines provided to the peripheral portion of the memory circuit and formed by a conductive layer different from the conductive layer of the input portion; and a contact hole for connecting between the two conductive layers at a selected input portion. The selected input portion connected by the contact hole is set or clamped to a predetermined logic level by the power source line. This enables a change of the memory capacity or the function of the memory block to satisfy customer requirements.
