Title: Production of magnetic head
Inventor: YAMAMOTO TATSUSHI
IPC: G11B5/127
Filed: 1990-03-19
Abstract: PURPOSE:To enhance working accuracy and to allow recording at a higher density in a wider frequency band by using ion milling for working the soft magnetic thin films in the peak parts on the respective groove wall surfaces to constitute gap parts and utilizing the self-shadowing effect of the peak parts on the respective groove wall surfaces. CONSTITUTION:V-grooves 11 are formed at the pitch A corresponding to the thickness of the magnetic head on the surface of a substrate 7. Alloy thin films 3 are formed by a sputtering method, etc., on the side walls 9 of the V-grooves and the thin films 3 of the soft magnetic alloy in the peak parts 12 are worked down to the thickness of the track width by utilizing the shelf-shadowing effect of the peak parts 12. The grooves 11 are then packed with low melting glass 8 and the substrate is cut at a plane 15 orthogonal with the grooves to form core pieces 16. A window for coiling is formed in succession thereto and the surfaces facing the gaps are precisely polished to form gap spacers. Surfaces 17 are then pressurized and fixed to face each other and are adhered by the low melting glass 8. The block is then parted to magnetic head chips 19. The working accuracy is enhanced in this way. The recording at the higher density in the higher frequency band is executed in this way.

Title: Electrostatic capacitance type level meter
IPC: G01F23/26
Filed: 1992-03-27
Abstract: PURPOSE:To keep droppings from stacking on the top surface of an upper electrode even when the area thereof is enlarged by arranging the upper electrode to be a hollow closed cylinder to achieve a hither sensitivity with an increase in the electrostatic capacitance of an instrument. CONSTITUTION:In an upper electrode 1, a cylinder-shaped metal pipe 2 with 70mm (diameter) X 150mm (length) X 1.6mm (thickness), for instance, is mounted at an effective measurement section of a level meter by welding. Both ends of a cylinder are covered with a disc and welded. With such a simple arrangement, sensitivity can be upgraded with higher electrostatic capacitance. As the upper electrode 1 is made cylindrical in shape, there is no directivity while no dropping will not stack on the top surface thereof. The apparatus is made closed hollow and hence, very light. Thus, the sensitivity rises with an increase in the electrostatic capacitance of an instrument thereby enabling the obtaining of the level meter with no droppings stacking on the top surface that upper electrode 1 even when the area of the upper electrode 1 is enlarged.

Title: Semiconductor logic circuit device of electrostatic induction type
Inventor: UEDA MASAHIRO
IPC: H01L29/80
Filed: 1978-06-13
Abstract: PURPOSE:To make it possible to increase a drain current without reducing an operation speed by forming a semiconductor region of the same conduction type as a gate region under a drain region and next to the gate region. CONSTITUTION:At the boundary part between channel region 10 under drain region 20 and high-density semiconductor substrate 1, P-type region 50 is formed. Since gate region 30 is formed surrounding drain region 20, region 50 is close to gate region 30. As a result, a current flows right under gate region 30. In an OFF mode, equalizing gate electrode 300 to source electrode 100 in terms of voltage cuts off a drain current through expansion D1 of a depletion layer from region 30 to region 10 and expansion D2 of a depletion layer from region 50 to region 10, and consequently both W and L of region 10 can be elongated, so that this area can freely be widened corresponding to the drain current.
