Inventor: HOSHINO KOZO
IPC: C22C21/06
Filed: 1989-08-11
Abstract: PURPOSE:To offer Al alloy stock free from the generation of defects such as crush and recording errors in a magnetic head in the using stage as manufactured articles by specifying the content of Mg, the content of Fe and Si in impurities and the content of nonmetallic inclusions detected by diamond cutting evaluation. CONSTITUTION:The Al-Mg alloy for mirror-like finishing is constituted of, by weight, 3 to 6% Mg and the balance Al with impurities in which the content of Fe and Si is respectively regulated to <0.008% and in which the content of nonmetallic inclusions detected by diamond cutting evaluation is regulated to <=1ppb (the piece number of the inclusions per face in a base having 242mm external size is regulated to <= one). For manufacturing the alloy, in the stage of refining and casting a high purity metal, filtering is executed at <=5g/cm.min flow rate of the molten metal by using a filter in which crushed grains having 500mu average grain size and are burned at 38 to 41% porosity.

Title: Transfer-error measuring apparatus
Inventor: MAEHARA OSAMU
IPC: G01M13/02
Filed: 1988-08-23
Abstract: PURPOSE:To apply the title apparatus to objects to be measured in a very broad range by performing frequency division based on an integer ratio that is approximate to a gear-tooth ratio, and correcting the error in an intermeshing ratio by computation after the frequency dividing pulse is converted into a numerical value. CONSTITUTION:For example, in a gear system to be measured 1 wherein a gear-tooth ratio between an output shaft and an input shaft is 321/123 ( 2.6), pulse signals having the different frequencies are outputted from pulse generators 11 and 12 and introduced into frequency dividers 13 and 14. A ratio [2] at the integer part of the gear-tooth ratio is used as a temporary gear-tooth ratio so that both outputs have the approximate frequencies in the frequency dividers 13 and 14. The frequency dividing ratios for the frequency dividers 13 and 14 are set at 1/2 and 1. Then said frequency dividing pulse signals (a) and (b) are introduced into period measuring devices 15 and 16. Thereafter, the counted value in the measuring device 15 is sent into a multiplier 17. The value is multiplied by a correcting coefficient K=321/123X1/2 based on the temporary gear-tooth ratio 2 and the true gear-tooth ratio 321/123. The deviation between the output values of the multipliers 16 and 17 is divided by one period in a divider 18. The transfer error is computed regardless of the number of rotations of the gear system 1.

Title: Sampling capsule and sampling method
Inventor: HONMA HARUO
IPC: G01N1/10
Filed: 1991-08-22
Abstract: PURPOSE:To enable a liquid organic compound to be sampled precisely and accurately by adsorbing a liquid organic compound to an adsorption carrier of a sampling capsule where the adsorption carrier for adsorbing the liquid organic compound is provided at a bottom part within a metal capsule, compressing the capsule for sealing, and then measuring a mass. CONSTITUTION:An adsorption carrier 2 for adsorbing a non-volatile or volatile liquid organic compound is provided at a bottom part within a metal capsule 1. A steam pressure of the organic compound is reduced remarkably due to the adsorptior carrier 2, thus preventing evaporation of the volatile liquid sample during sampling operation and reduction in amount. Also, even if the capsule is compressed for eliminating air within the capsule 1, the liquid sample which is retained at the adsorption carrier 2 does not blot outside the capsule. When sampling the liquid organic compound, the capsule where the carrier 2 is provided at a bottom part within the capsule 1 is subjected to tare elimination on a micro balance and then a required amount of liquid sample is adsorbed to the carrier 2. After this, the capsule 1 is compressed for eliminating air and then sealing is made for enabling a mass of the sample to be weighed.

Accordingly, for example, the sharing ratio of the external input output signal and the input output gate can be used as the index. For the common partial logic, the part of the old gate logic corresponding to it is selected and for the uncommon part, the part of the intermediate gate logic corresponding to it, they are unified, and thereby, the new gate logic is generated in which the actually mounted information and the labor optimizing information concerning the unnecessary part of the changing of the old gate logic are preserved.
