Title: Circuit board and manufacture thereof
Inventor: HORIKOSHI EIJI
IPC: H05K1/05
Filed: 1991-07-30
Abstract: PURPOSE:To enable a circuit board to be lessened in size and weight by a method wherein an electric circuit is formed on a base material made of magnesium, magnesium alloy, magnesium base composite material, or combinations of them. CONSTITUTION:Through-holes 105 are bored in a magnesium alloy base material 101 by drilling. Then, an electrodeposition coat 111 is formed on the whole surface of the base material 101 by the cation electrodeposition of amino group- introduced epoxy resin carried out at a prescribed current density. Photosensitive polyimide is applied onto the electrodeposition coat 111 on the upside of the base material 101 through spin-coating to form a polyimide film 121. At this point, as magnesium is chemically active, it is low in corrosion resistance, so that it is required to be coated with an anticorrosion film or the like through an electrodeposition method.

Title: Method for forming metal interconnection in integrated circuit and the metal interconnection in the circuit
Inventor: BOREL JOSEPH
IPC: H01L21/3205
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To form a metal interconnecting track for connecting an insulated gate of a transistor to a discharge diode, by forming an interconnecting track without altering a various element of the interconnection and a position of a geometric structure. SOLUTION: A track PCN has track elements EL1, EL2 extended along a metallized level M1. An end EX1 of the element EL1 is connected to a gate GR of a transistor through one interconnecting hole or via, and an end of the element EL2 is connected to a diode region DD through one via. And, the ends of the elements EL1, EL2 are connected to a track element ELS of a metallized level M2. Accordingly, in the case that the track PCN is extended only along the one metallized level, charge is removed by a discharge diode while a metal track is etched. Thus, a gate oxide is not deteriorated, and the interconnection can be formed without altering an initial geometric structure.

Title: Superconducting magnet device
Inventor: KIMURA SHINICHI
IPC: H01F6/00
Filed: 1987-07-31
Abstract: PURPOSE:To prevent the Joule heat from being generated by a method wherein a high-temperature superconducting material is attached to both end parts of a coil to which a superconducting coil composed of an ordinary superconducting conductor and electric-current leads are connected. CONSTITUTION:High-temperature superconducting materials (composed of an oxide of Y, Ba and Cu or the like) 12 are attached to peripheries of both end parts of a superconducting coil 2 composed of an ordinary superconducting conductor. Even if a temperature at both end parts 2a of the coil is increased due to the penetrating heat from electric-current leads 11 or due to a drop in a cooling effect when a liquid level of liquid helium 4 is lowered and both end parts become a normal conducting state, the high-temperature superconducting material remains in a superconducting state because its critical temperature is high. As a result, an electric current flows to the high- temperature superconducting material whose electrical resistance value is zero, and the Joule heat is not generated. By this setup, even if the temperature at both end parts 2a of the coil is increased, the high-temperature superconducting material remains in the state; the Joule heat is not generated; the coil as a whole is not set to the normal conducting state.

Title: Recording and reproducing device
Inventor: SATOMURA SHIGEYUKI
IPC: G11B20/18
Filed: 1988-07-30
Abstract: PURPOSE:To simplify a circuit constitution by causing the width of a recording head to be two-fold or above that of a track pitch, simultaneously, providing a level detector to detect the level of a reproducing signal and detecting a recording error by means of the output of the level detector. CONSTITUTION:When the width of a pair of recording heads HW1 and HW2 is made two-fold or above that of a track pitch Tp, since the recording of 2Tp or above is executed by the recording head one before an instantaneous clog even when the instantaneous clock is generated to one channel of a pair of recording heads HW1 and HW2, a drop-in is not generated. Consequently, since an azimuth is the azimuth inverse to the track recorded by 2Tp or above by the recording heads HW1 and HW2 one before even when reproducing heads HR1 and HR2 pass on the track to be instantaneously clogged at the time of read-after-write, an RF signal is not obtained at all. The fact that the RF signal does not exist is detected by a level detector 10, and the recording error is detected. Thus, the circuit constitution can be simplified.
