Title: Magnetic erasure head
Inventor: YAMASHITA KEITARO
IPC: G11B5/127
Filed: 1985-12-06
Abstract: PURPOSE:To improve erasure width accuracy by jointing a pair of magnetic core halves through a gap spacer so as to provide an erasure gap and disposing conductors on both sides in the track width direction of the gap. CONSTITUTION:A pair of magnetic core halves 1 and 2 made of Mn-Zn ferrite are jointed through a gap member made of SiO2, etc., to form the gap (g), and are machined in the vicinity of the gap (g) to regulate the prescribed track width Tw. A conductive material 6 made of Cu, etc., is coated over a pair of halves 1 and 2, and a nonmagnetic material 5 such as high melting point glass is filled. An erasure signal supply coil winding hole 4 is added to the half 2. When an erasure AC magnetic filed is impressed on the head, an eddy current is generated in the conductor 6. Accordingly, the flux leaking in the track width direction on both sides of the erasure gap (g) is canceled by the eddy current of the conductor to prevent the occurrence of an oozing magnetic field, whereby only a desired field can be erased without the deterioration of picture quality.

Title: Semiconductor integrated circuit
Inventor: HORIGOME OSAMU
IPC: H01L29/78
Filed: 1988-10-31
Abstract: PURPOSE:To prevent the deterioration of characteristics by providing one conductivity type impurity layer having a relatively low impurity concentration in a semiconductor substrate region between an opposite conductivity type impurity layer and an insulating film having a relatively low impurity concentration. CONSTITUTION:A thermal oxide film 2, a polycrystalline silicon gate electrode 3 are formed on a p-type silicon substrate 1 and ion implantation of n-type impurities is performed by using the foregoing film 2 and gate electrode 3 as masks to form an n<-> type diffusion layer 4. Then ion implantation of p-type impurities is performed to form a p<-> type diffusion layer 7. An SiO2 film is deposited with a CVD process and then sidewalls 5a are formed by performing anisotropic etching. Subsequently, ion implantation of the n-type impurities is performed and source and drain diffusion layers 6 are formed by annealing. Further, selective etching of the thermal oxide film 2 as well as the p<-> type diffusion layer 7 allows the surface of the n<-> diffusion layer 4 to be exposed to the outside to make a contact hole. Such a configuration causes carries at a part of A to change steeply from p-type to n-type and the concentration of an electric field takes place. As the carriers are apart from thermal oxide film 4 as well, it is hard to give rise to deterioration of characteristics in transistors such as variations of threshold values because of hot carriers, lowering of mobility and the like.
