Title: Driving device for sewing machine
Inventor: ASANO TAKESHI
IPC: D05B69/32
Filed: 1994-10-07
Abstract: PURPOSE: To sufficiently reduce the vibration of a sewing machine frame, especially, that of an arm by eliminating the vibration of a bearing by controlling a driving means and displacing auxiliary mass by a control means. CONSTITUTION: A control circuit 88 controls the driving of piezoelectric actuators 94a, 94b so as to minimize the vibration detection signals of acceleration sensors 90a, 90b setting signals from an encoder 60 and a needle bar position detector 62 as input signals. The piezoelectric actuators 94a, 94b perform vertical expanding/contracting motion by a control signal from the control circuit 88, and drive weights 92a, 92b vertically. The reaction of an inertia force generated by the vertical driving of the weights 92a, 92b is applied to the bearings 33a, 33b, and it is synthesized with the reaction generated by the motion of a needle bar mechanism and a needle thread take-up mechanism, consequently, the reaction applied to the bearings 33a, 33b can remarkably be reduced.  Therefore, the vibration generated in a sewing machine arm 22 can remarkably reduced, and a generated noise can also be reduced.

Title: Cholesterol lowering agent
Inventor: HIRATA OSAMU
IPC: A61K38/44
Filed: 1994-10-07
Abstract: PURPOSE: To obtain a cholesterol lowering agent based on principle lowering blood cholesterol concentration by decomposing enteric bile acid by oral administration of the agent, inhibiting reabsorption at the end of ileum and consuming cholesterol which is a raw material for bile acid. CONSTITUTION: This cholesterol lowering agent is obtained by immobilizing 3α-hydroxysteroid dehydrogenase anti/or 3α-hydroxycholanate dehydrogenase which is a bile acid hydrolase onto a polymer carrier. The polymer carrier is water-insoluble and a carrier capable of carrying out immobilization reaction with bile acid hydrolase is preferable as the polymer carrier and p- aminobenzylcellulose, polyaminopolystyrene, CNBr-activated cephalose, ethylene- maleic acid copolymer, agarose, etc., is exemplified as the polymer carrier and the particle diameter is preferably 1μm to 5mm, especially 5μm-1mm. Since the agent uses bile acid hydrolase, the absorbed part is not saturated as saturated in ion exchange resins and the agent effectively inhibits re-absorption of bile acid by using a small amount of the agent and readily can lower blood cholesterol value.

Filed: 1994-10-11
Abstract: PURPOSE: To prevent inversion by using an equalizer characteristic switching pulse to cover reduction in an envelope to switch an FM equalizer characteristic so as to suppress a reproduction FM signal lower side band. CONSTITUTION: A dropout detection circuit 5 detects a part below a threshold level of an envelope of a reproduced FM signal and generates a dropout pulse Pd. Since intervals of zero points of the envelope are identical to each other in the case of a constant search speed, a delay circuit 9 is used to produce a characteristic switching pulse P1 of 1 to 2H width just before a succeeding pulse Pd and a characteristic switching pulse P2 just after the pulse Pd and they are fed to an FM equalizer 1. The characteristic of the equalizer 1 is switched for only the part where the envelope of the reproduced signal is reduced by using the pulses P1, P2 to improve the S/N and to prevent inversion.  Furthermore, the signal is replaced only in the vicinity of the zero point of the envelope through dropout compensation, no mosaic noise bar takes place and a high definition search image is obtained without inversion.
