PROBLEM TO BE SOLVED: To provide an electric cable structure capable of reliably maintaining soundness of electric components while obtaining the desired waterproof effect with a relatively simple constitution. SOLUTION: The electric cable structure includes a primary-side electric cable 1a, a secondary-side electric cable 1b dividedly arranged to the primary-side electric cable, an intermediate substrate 13 for connecting the primary-side electric cable and the secondary-side electric cable, and a hot melt resin mold part 21 for covering the intermediate substrate. A covered tube of an end part on the intermediate substrate side of the primary-side electric cable is separately arranged so as not to be superposed on the intermediate substrate, and a covered tube of an end part on the intermediate substrate side of the secondary-side electric cable is also separately arranged so as not to be superposed on the intermediate substrate. Even if moisture and oil infiltrate from the primary-side electric cable side, this infiltration is checked by an intermediate substrate-treating part 11 composed of the intermediate substrate and the hot melt resin mold part so as not to infiltrate into the secondary-side electric cable side.

PROBLEM TO BE SOLVED: To provide a power supply device for driving a motor, which collects a regenerative current even during low speed operation of a motor with a low induced voltage, and reuses most of the extracted energy. SOLUTION: The power supply device for driving the motor is equipped with: a main battery; an auxiliary battery; a driver that supplies power, supplied from the main battery, to a motor so as to drive the motor; a large capacity capacitor connected in parallel or in series with the auxiliary battery; a charging means that supplies a current to the auxiliary battery so as to charge the auxiliary battery and supplies a current to the large capacity capacitor so as to store power in the large capacity capacitor; and a control means that controls switching between "powering" for supplying power, supplied from the main battery, to the motor via the driver and "regenerating" for collecting electric energy generated from the motor, and also executes control such that, when the speed of the motor is sufficiently fast in the "regeneration", a regenerative current is made to flow to the main battery via the driver, and when the speed of the motor becomes slow, the regenerative current is made to flow to the large capacity capacitor via the charging means.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a fine structure, in which a fine structure such as a three-dimensional fine structure, a pattern of μm order or less and a binary cubic optical element is easily formed only by vacuum deposition and etching. SOLUTION: Structures each provided with a fine rugged pattern are arranged so as to be confronted in a state where each rugged pattern side is directed to a vacuum deposition source. At that time, each structure is tilted only by a prescribed angle to the vacuum deposition source in such a manner that a part of the recessed part in the fine rugged patter is not vapor-deposited. In such a state, vacuum oblique deposition is performed, and an etching mask is deposited and installed on each fine rugged pattern side. Then, etching is performed, whereby each fine rugged patter finer than the above fine rugged pattern is formed. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a constant-voltage/constant-current power supply device which can reduce stress by making a voltage and a current approximate set values by shortening a delay time at the transition of a constant-voltage (CV) control mode and a constant-current (CC) control mode. SOLUTION: The constant-voltage/constant-current power supply device comprises: a switching circuit which outputs an output voltage set by switching an input voltage; a constant-voltage (CV) error amplification circuit which outputs an error by comparing an output voltage outputted from the switching circuit and a constant-voltage (CV) set voltage; a constant-current (CC) error amplification circuit which outputs an error by comparing a charging output current outputted from the switching circuit and a constant-current (CC) set voltage; a control mode selection circuit which selects either the constant-voltage (CV) control mode or the constant-current (CC) control mode whichever becomes effective; and a transition responsiveness improvement circuit which is arranged in the control mode selection circuit, and shortens the delay time at the transition of the control modes by reducing a voltage difference between a constant-voltage (CV) control voltage and a constant-current (CC) control voltage.
