Title: Method for coupling lubricant to magnetic disk
Inventor: RIN BOKUZAN
IPC: C10N40/18
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic disk having zone groups which are separate in changed lubricant layer thicknesses in order to reduce the floating static friction on a magnetic disk surface. SOLUTION: Protective film layers having the discriminated zone groups of different compositions are first sputtered on a disk surface by using discriminated masks under different sputtering conditions. The surfaces of the protective film layers are then uniformly coated with the lubricant layer. Part of the lubricant bonds to the protective film layers and forms the bonded lubricant layers and the thicknesses of the bonded lubricant layers correlate with the characteristics of the protective film layers and therefore the free lubricant layers having the zoned thicknesses are resultantly formed. The free lubricant layers are formed from the remaining lubricants. The zoned lubricants therefore reduce the floating static friction.

Title: Television signal receiver
Inventor: NAKAMURA EIJI
IPC: H04N5/50
Filed: 1993-09-30
Abstract: PURPOSE:To prevent the occurrence of channel mispreset by temporarily stopping the change of a channel selecting voltage and detecting the tuning point after the change of a TV signal presence/absence detection signal to the signal presence state. CONSTITUTION:At the time of automatic channel selection, an AGC voltage monitor circuit 23 is switched to the tuning state based on the change of the channel selecting voltage to monitor whether an AGC voltage Sc reaches a threshold VTH corresponding to TV signal reception in a weak electric field or not; and when it reaches this threshold, a reach discrimination signal is supplied to a channel selecting circuit 24. A channel selecting voltage control means, a reception confirmation means, and a tuning point detection control means consist of software of a microcomputer and are built in the circuit 24. The channel selecting voltage control means temporarily stops the change of the channel selecting voltage by the input of the reach discrimination signal. The reception confirmation means discriminates whether a detection signal Sb is inverted into the high level at the end of temporary stop of the channel selecting voltage or not. The tuning point detection control means permits the conduct of tuning point detection processing only when confirming the inversion of the detection signal Sb to the high level.

Filed: 1991-10-17
Abstract: PURPOSE:To perform access to sub array data as one part of two-dimensionally arranged data by once issuing and executing a transfer instruction at a storage device such as the distributed memory of a multiprocessor system. CONSTITUTION:A sub array access address generating means 101 generates the addresses of respective data from the second column of each line to the 11-th column at the terminal with an address S1-1 on a local memory for the head data of a sub array as an initial value by successively adding a distance D1 between elements to the address of data at the preceding column of the row and generates the address of data at the first column of each row behind the second row by adding a fixed distance D2 between rows to the address of data at the 11-th column in the terminal of the preceding row. Thus, each address for accessing the entire sub array data can be easily generated only by once issuing the access instruction of the sub array data.
