Title: Preparatory treating method of treating chamber maintenance of semiconductor treating device
Inventor: MAKITANI MASAHIRO
IPC: H01L21/205
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a preparation treating method of treating chamber maintenance of a semiconductor treating device by which the temperature in the treating chamber can be dropped efficiently and the maintenance time of the chamber can be shortened remarkably. SOLUTION: The pressure, time, and dropped temperature at the time of performing chamber vent are set in a prescribed recipe. After a film forming chamber is evacuated to a vacuum, an N2 gas is supplied to the chamber (chamber vent) through a pump until the pressure in the chamber becomes the pressure set in the recipe and the inside of the camber is maintained in the same state until the time set in the recipe elapses (steps 101-103). When the temperature in the film forming chamber reaches the target dropped temperature when the holding time elapses and the pump is completely stopped, a batch purging treatment is performed. When the temperature does not reach the target value, the steps after 101 are repeated until the temperature in the film forming chamber reaches the target dropped temperature set in the recipe.

Title: Method and device for magnetic recording
Inventor: SEKIGUCHI KEISUKE
IPC: G11B15/467
Filed: 1989-11-30
Abstract: PURPOSE:To simplify a mechanism part and to record an auxiliary data with a small redundancy by converting a prescribed bit data into a data with less continuity in one value of either high level or low level, eliminating that value of less continuity and recording it after frequency modulation (FM) to a prescribed track. CONSTITUTION:A data D for showing the auxiliary data is supplied to an 8-bit address bus AB of a ROM 8, and a converted data DH is read from a 16-bit data bus of this ROM 8. The converted data S1 has less continuity of, for example, the low level '0', and when the data S1 excluding the low level '0' parts is frequency-modulated, parts which are frequency-modulated out of a signal S3 after frequency modulation are diminished. Therefore, when this signal S3 after frequency modulation is reproduced, a cell clock by the signal S3 is feasible. Then, the redundancy of a part for converting the prescribed bit data D into the data S1 with less continuity of one value of either high level or low level is less than about double the data D. By this method, the redundancy can comparatively be made small, and the mechanism part can be simplified as well.

Title: Input signal amplifier
Inventor: BAAS REINER
IPC: G11B7/09
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To simply and appropriately adjust the gain of an input signal amplifier by arranging resistors with the power of '2'. SOLUTION: An addition signal is inputted to an A/D converter 3, and it is converted digitally. The highest bit controls the switch SR of a minimum resistor R, and the lowest bit is supplied to a resistor 16R with the maximum resistance value through a switch S16 R. The respective bits of the digitized addition signals operate on the switches SR-S16 R and the switches open/close connection according to the bits. The gain of the input signal amplifier 1 of error signal amplification corresponds to an error signal in the selection of the corresponding values of the resistors R-R16 , where the two adjacent resistors differ by the power of '2'. When the error signal becomes twice with the high reflecting force of a recording medium, for example, conductance also becomes twice and the gain is reduced to a half. The A/D converter 3 is controlled by a clock signal T.  Thus, response speed suitable for the gain can be adjusted from outside by a signal T.
