Title: Arm feeding unit
Inventor: KITAZAWA KEIO
IPC: G11B21/04
Filed: 1978-07-13
Abstract: PURPOSE: To pick up accurate signals and to prevent the damgages to the needle and disc, by detecting the magnetic change due to the displacement of needle arm and controlling each position at carrying so that the arm can be constantly placed to the trace groove of disc.  
     CONSTITUTION: The magnetic change is detected with the displacement of the needle arm 21. The magnetic detector consisting of the first and second Hall elements 36 and 37 is provided by opposing to the NS pole of the permanent magnet 35. The output of the Hall elements 36 and 37 is inputted to the comparison circuit 38, where the output voltages V 1 , V 2  of the elements 36 and 37 are compared to obtain the output corresponding to the difference. The DC output is inputted to the motor control circuit 41 via the low pass filter 39 and the gate circuit 40. The control circuit 41 controls the number of revolutions of the motor 48 for arm feeding motor driving the arm unit. Thus, the relative position of the needle to the disc can automatically be controlled to prevent the damages to the needle and disc.

Title: Extracting system of feature pattern
Inventor: OKADA KUNIHIRO
IPC: G06K9/46
Filed: 1983-05-18
Abstract: PURPOSE:To increase a processing speed by extracting a pattern of optional directivity without losing the information on a part where patterns of different directivities cross each other. CONSTITUTION:An original pattern 50 is thinned and the directivity of the pattern can be extracted even at an intersecting point. Then directional patterns 51-54 are extracted by a space filter. In addition, the thickening process is carried out for the pattern after the directivity is extracted in order to exclude beard and noise components produced by the thinning process. An AND is obtained between the pattern 50 and directional patterns 55 and 56 which underwent the thickening process in order to delete the crush of a pattern due to the thickening process. Thus a vertical pattern is obtained. In the same way, a horizontal pattern is also obtained.

Title: Surfactant
Inventor: SHIOMI HIDEKAZU
IPC: A23L29/10
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a surfactant which shows a high safety to a human body, high biodegradability, an acid resisting power, cosmetically whitening and moisture retaining effects and lessens the dependence upon temperature. SOLUTION: An aqueous sericin solution is extracted from a sericin contained in a cocoon or silk with water and its pH value is adjusted to about 3-5 by an organic acid or an inorganic acid. Further, an organic flocculating agent or an inorganic flocculating agent is added to deposit the sericin, which is, in turn, filtered and dried into a solid sericin. The sericin thus obtained is odorless and tasteless and can be used for mayonnaise or the like as food, for cream or the like as a cosmetic and for a hand soap or the like as a detergent, all being in the form of a surfactant. This surfactant is free from functional deterioration at a low temperature and denaturation and coagulation at a high temperature, so that the range of temperatures for applications is wide.  The sericin itself possesses moisture retaining and cosmetically whitening effects, and further, suppresses the oxidation of oils/fats in an emulsion through anti-oxidation action to maintain the oils/fats in a good condition for a long time. The sericin is a natural product, hence a high safety to the human body and environments is secured.
