IPC: A61B10/00
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To evaluate a mental fatigue refreshing substance to be tested, by applying a stress to a non-human animal to which the substance to be tested is administered, and measuring a concentration change of alanine in blood caused by the application of the stress.

Title: Separator for fuel cell
Inventor: TOYAMA YUKIFUMI
IPC: H01M8/02
Filed: 1993-05-19
Abstract: PURPOSE:To reduce weight, dispense with grooving work, and facilitate molding by using a plurality of first layers consisting of conductive resin and second layers consisting of conductive resin and conductive fiber arranged between the layers to constitute a laminated body. CONSTITUTION:A separator is formed of first layers 21, 23, 25 made conductive by mixing carbon powder or a metal powder to an epoxy resin; and second layers 22, 24 obtained by impregnating carbon fibers with the above conductive resin. A reaction gas comes in from through-holes 26, 28, runs into the groves 33, 37 of a reaction surface through passages 32, 36, and flows out from through- holes 31, 29 through passages 34, 38 after the reaction. A cooling water comes in from a through-hole 27 and flows out from a through-hole 30 through a reaction surface cooling passage 35. Since the main material of each layer is formed of the resin or fiber with low specific gravity, copying molding from a mold can be performed together with reduction in weight, dispensing with grooving work. Further, since the second layers are reinforced by the fiber, both strength and rigidity can be made equal to those of a metal.

Title: Occluder for mechanical coeur succedaneous valve
Inventor: NAEMURA KIYOSHI
IPC: A61F2/24
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a remarkable effect of a closing start by a gravitational torque while increasing a contribution to the improvement of life of a patient and the quality of a living, in addition to the improvement of operation performances by a method wherein by utilizing the gravitational torque, a function to start a closing before a reverse flow occurs, is provided. SOLUTION: The cross sectional shape of this occluder is made a trapezoid instead of a rectangle. Also, the gravity center of the occluder is moved from the rotational center axis 3 to the direction of the center of a valve mouth ring 1, and the occluder 2 is made easy to rotate in the direction of a closing angle location 5 by the gravitational torque. By this method, accompanying the start of a flowing into a left ventricle, the occluder 2 at a maximum opening location 4 starts a closing before a reverse flow occurs by the gravitational torque, under a state wherein there is almost no flow due to a relaxation of the left ventricle before a contraction.  For example, when the inner diameter of the valve mouth ring 1, which is frequently used at the location of a valva mitralis, is 24 mm, as results of experiments and calculations, the dimension can be determined in such a manner that the gravitational torque may become 4×10<-6> Nm, to the torque of a fluid force due to the reverse flow, which is 1,000-10,000×10<-6> Nm.

Filed: 1978-09-25
Abstract: PURPOSE: To obtain excellent recording at the reception side, by transmitting only the signa of transmission original through the elimination of the read-in signal not required toward main scanning direction.  
     CONSTITUTION: The output of the original detector 7 turned on at the tip of the transmission original 2 and turned off at the rear edge is inputted to the AND gate 24 via the input terminal 19. This output is fed to the unit consisting of the pulse generation circuit 25, counter 27, and switch group 26, the output of the counter 27 is fed to the counter 28 and the length of the transmission original 2 is outputted from the counter 28. Further, the signal output period from the positive output terminal Q of FF 29 corresponds to the length of the transmission original. Since the output of the AND gate 33 is the signal determining the length of original, one scanning signal read in the photo electric cnversion unit 34 (including unnecessary part) is gated by the gate 35 while the gate 33 signal is inputted, then disired signal only is picked up at the output terminal 17. When this signal is received at the reception side, since unnecessary part is not recorded, sharp and excellent recording can be obtained.

Abstract: PURPOSE: To precisely determine a desired rear wheel steering by evaluating whether a measured vehicle speed value is credible or not, and retrieving the rear wheel steering angle by use of the vehicle speed value and the front wheel steering angle when it is credible, and by use of only the front steering angle when it is not credible.
