Title: Floating type magnetic head and production of the same
Inventor: NAITO TSUTOMU
IPC: G11B21/21
Filed: 1991-11-06
Abstract: PURPOSE:To suppress an increase in a coefft. of static friction and to decrease the spacing between a magnetic head and a magnetic disk by providing holes or grooves on ski surface and filling up a lubricant into the holes or grooves. CONSTITUTION:A material, such as carbon, having a lubricating function is packed in the holes or grooves of the ski surface 10. The friction on the surface of the thin-film magnetic disk is, therefore, decreased when CSS is repeated. Thus, the increase in the coefft. of static friction by the repetition of the CSS is suppressed. The formation of a thinner lubricating film on the surface of the thin-film magnetic disk is possible to thin and consequently, the gap between the magnetic head and the magnetic disk is decreased.

Title: Look ahead carry generating circuit
Inventor: FUJIWARA MIKIO
IPC: G06F7/50
Filed: 1989-11-08
Abstract: PURPOSE:To perform an operation at high speed by executing the carry operation corresponding to value '0' of a carry signal Cin propergated from a low- order block and the carry operation corresponding to value '1' in parallel and selecting operation results in accordance with the value of the propergated carry signal Cin. CONSTITUTION:Cin, Pi, and Gi are substituted with C41+j, P41+j, and G41+j (j=0 to 3) in the figure, and blocks 1 to 3 generate the carry signal for C41-1='0', and blocks 4 to 7 generate the carry signal for C41-1='1'. Blocks 8 to 11 select output carry signals in accordance with the signal value of C41-1. Especially in the block 8, C41+3 is generated as the propergation signal to a high-order carry generating circuit. Consequently, carry generating operations of high-order blocks corresponding to two signal values of Cin are executed before the propergation of Cin from low-order blocks when signals of an augend and an addend are inputted, and operation results are selected by the signal value of Cin. Thus, the circuit is cascaded to shorten the carry generation time.
