Title: Dc testing device for semiconductor
Inventor: SATO TADASUKE
IPC: G01R19/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive, small-sized, and highly reliable DC testing unit. SOLUTION: A set output value is converted into a density-modulated 1-bit pulse train by means of a ΔΣ modulator 16 and supplied to a low-pass filter 21 through a D-flip flop 19 and a 1-bit D/A converter 20. As a result, the value becomes a highly accurate DC voltage. The voltage is supplied to a load 1 through a current detecting resistor 2 after the voltage is amplified by means of a main amplifier 5. The voltage across both ends of the resistor 2 is detected by means of a differential amplifier 3 and inputted to a clamp circuit 17. In the circuit 17, the voltage is compared with the outputs of D/A converters 13 and 14 and, when the voltage exceeds a positive clamping value, the output of the circuit 17 becomes '1' and a data selector 18 works to lower the output voltage by not outputting the output pulse train of the modulator 16, but '0'.  When the output voltage drops and a load current (i) becomes smaller, the output A becomes '0' and the load current (i) is stabilized at the positive clamping value.

Title: Production of crosslinked polyolefin molding
Inventor: MIYATA HIROYUKI
IPC: C08L23/02
Filed: 1990-11-21
Abstract: PURPOSE:To obtain a crosslinked polyolefin molding improved in the dispersion of degree of crosslinking in the direction of the thickness by irradiating a crystalline polyolefin with various ultraviolet rays of different wavelengths under specified temperature conditions. CONSTITUTION:The objective molding is obtained by irradiating a crystalline polyolefin with various ultraviolet rays of different wavelengths under the conditions of a temperature equal to or higher than the crystalline melting point of the crystalline polyolefin. When the crystalline polyolefin is at a temperature equal to or higher than its crystalline melting point, its entire crystalline part is in a molten state, and the transparency is good. Therefore, the markedly improved transmission efficiency of ultraviolet rays increases the crosslinking efficiency. Polyethylenes such as low-density polyethylene, high-density polyethylene, linear polyethylene, ultralow-density polyethylene and ultrahigh-molecular- weight polyethylene are particulalry desirable as the crystalline polyolefins because they can give moldings of high crosslinking efficiency.
