Title: Insulation method of superconducting element wire
Inventor: GOTO KENJI
IPC: H01B12/10
Filed: 1991-08-21
Abstract: PURPOSE:To prevent the conductivity lowering of a stabilization layer and also eliminate pollution problems by forming a coating layer composed of Ni on an outer surface of the stabilization layer, and then applying oxidation treatment to form a high electricity resistant layer consisting of NiO. CONSTITUTION:A superconductive element wire 12 is formed by means of covering a core part 10 with a tube body composed of pure copper to reduce diameter and so on, and then a coating layer 25 consisting of Ni is formed on the outer periphery of the element wire 12 to obtain a coating composite wire 26. Then the layer 25 is changed into a high electricity resistant layer 27 by anode- oxidation-treating or chemical-conversion-treating the wire 26 to make oxidation treating, obtaining an insulating superconducting wire 28. After that, an anode oxidation treatment is made to enable the almost all of the Ni forming the layer 25 to be turned into NiO. Finally plural element wires 28 are collected to make a stranded wire, and diffusion heat treatment is applied to it to obtain a superconducting stranded wire 31 having structure in which insulation-treated superconducting wires 30 are twisted. This is advantageous in the aspect of a superconducting characteristic, and also eliminates the conductivity lowering of a stabilization layer 34, preventing the pollution of the layer 34.

Title: Ink detection device, printer using the same, and control method
Inventor: MIYAHARA FUMIO
IPC: B41J2/175
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To detect the level of an ink liquid with high accuracy by a simple structure dispensing with a negative power supply. SOLUTION: The pulse signal generated from a pulse generation part 101 is supplied to a differentiation circuit constituted of a capacitor 102, a resistor 103 and the electrodes in the ink storage part 104 of an ink cartridge and the voltage applied across the electrodes is detected. Since a gate 105 is opened at this time only when the voltage applied across the electrodes is in a positive state, only a signal of positive voltage is supplied to a peak holding part 106. That is, a negative power supply becomes unnecessary in a processing circuit system. The peak obtained herein and predetermined voltage are compared by a comparator part 107 and the comparing result is outputted.

Title: Semiconductor device and manufacture thereof
Inventor: KOYAMA YUUGO
IPC: H01L21/52
Filed: 1992-09-02
Abstract: PURPOSE:To relax the effect caused by thermal expansion of a bonding agent upon a die and a semiconductor chip after having die bonded by separating respectively a die pad section into at least two portions which are identical to each other in area and shape. CONSTITUTION:The current semiconductor device tends to increase the number of I/O pins of semiconductor chips to comply with such demands as higher integration and more enhanced functions. This increases the size of semiconductor chips themselves currently and die. As for die pad-shaped lead frames, however, the heat of a bonding agent generated after having die-bonded, changes an expansion coefficient, thereby warping the die pads or the semiconductor chips. To solve this, a die 2 is divided into at least two parts and an IC chip is loaded in such fashion that it may rest on the divided parts. Therefore, this reduces a contact area and relaxes the effect of thermal expansion of the bonding agent on the die pad 2 and the semiconductor chip after the die bonding.
