Title: Drawing display device
Inventor: KOSEKI MINORU
IPC: G06T15/00
Filed: 1983-12-15
Abstract: PURPOSE:To improve a processing speed by detecting a face at the rear side of an object by a sign of the (z) direction component of a normal vector and omitting the calculation of the depth coordinates and the comparison as to the rear side face. CONSTITUTION:Coordinates of each apex of, e.g., a face P1 are fed to a normal vector operating circuit 6 from a terminal input. Then the polarity of the (z) direction component of the normal vector is operated. Since this value is negative, the coordinates are calculated by a z coordinate operating section 1 as to each picture element of the face P1, converted into picture elements and fed to a comparator 5. The comparator 5 compares them with the maximum value of (z) direction read from a Z buffer 2 and since the (z) coordinate value of the picture element calculated is smaller naturally, the depth corresponding to x, y coordinates of each picture element, e.g., (z) coordinate is written in the Z buffer 2. When the polarity of the (z) component is positivae, that is, in case of a face P2, no operation of the Z coordinate operating section 1 is conducted and no comparison by the comparator is conducted. In case of an overlapped object, the (z) coordinate of faces in the visual point direction is compared.

Title: Thin film magnetic head
Inventor: ITOU KAZUMA
IPC: G11B5/31
Filed: 1983-12-15
Abstract: PURPOSE:To improve the R/W efficiency of a thin film magnetic head by constituting a magnetic circuit containing two pairs of upper and lower magnetic layers connected in an 8-shape and transmitting a spiral thin film conductor through each hollow part of the 8-shaped magnetic circuit via an insulated layer. CONSTITUTION:A magnetic gap G prescribed by a nonmagnetic layer 6 is formed between the front edge part of a lower magnetic layer 2 and the front edge part of an upper magnetic layer 3. A magnetic circuit is formed in a loop crossed into an 8-shape by magnetic layers 2, 4, 5 and 3, and a conductor 8 passes through each hollow part of the 8-shaped loop. Thus the magnetic flux produced by a spiral conductor is caught by the magnetic layers with no loss. This improves the conversion efficiency of an electromagnetic transducer and therefore reduces the writing current to a magnetic recording medium to increases the reproduction output. In addition, the number of windings can be reduced to the conductor to prevent the increase of the cost.
