IPC: A61K35/58
Filed: 1984-08-24
Abstract: PURPOSE:To obtain a blood coagulation promotor for blood separation containing enzyme promoting blood coagulation at a low cost, by making HIME HABU discharge HIME HABU venom to separate it by a specified means once gathered in large amounts. CONSTITUTION:HIME HABU inhabiting in Amani and Okinawa Islands which is kept alive is made to discharge venom onto a laboratory dish to be gathered in large amounts, cooled and separated centrifugally and then, the supernatant thereof frozen dry. The matter thus dried is dissolved into a salttris buffer liquid dialyzed and then, the dialysis internal solution is separated centrifugally. After the supernatant is passed through a membrane filter, the filtrate is sent through a DE-52 cellulose-filled column. Adsorbed protein is made to elute with a linar increase in the concentration of salt in an elution liquid to obtain a fraction having no bleeding activity with a high thrombinomimetic activity. After further subjected to a biogel P-100 gel filtration twice, this fraction is dialyzed against distilled water and frozen dry. After a solution containing an stabilizing agent, antiseptic and the like is added thereto, the product undergoes an aseptic filtration and distributed into a vial to be frozen dry. Thus, a blood coagulation promotor can be obtained at a low cost.

An operator can selectively display one profile and change the time accompanying to one or more control points. The data on the motion data vs. time is automatically calculated on the whole profile by the controller while keeping the sectional linear contour of the whole profile.

Title: Pipe-type jumper device
Inventor: YOKOYAMA KAZUO
IPC: H02G1/02
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To make is possible to manufacture a pipe-type jumper device at low cost and eliminate the possibility of the occurrence of casting defect, by using, as an electrical connection with a jumper wire in an aluminum pipe, a connecting face obtained by flattening both the ends of the aluminum pipe itself by press so as to bring the inside surfaces in tight contact with each other, before heat treatment to the aluminum pipe. SOLUTION: Both the ends of an aluminum pipe 1 is flattened by press so that the inside surfaces will be brought into tight contact with each other, and an electrical contact 1a with a jumper wire is thereby formed before heat treatment to the aluminum pipe 1. A large number of bolt holes in two lines are formed in the electrical connection 1a in the direction of the axis of the aluminum pipe 1, and connecting sockets compression-joined with jumper wires are fit and bolted there. This obviates aluminum welding required in conventional methods, and thus makes unnecessary an ultrasonic flaw detecting process, which accomplishes cost reduction. Since press working is performed before a heat treatment process, cracking on the surface of aluminum pipes due compression is prevented.

Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To perform a reading operation at a high speed by minimizing a pulse width required for selecting a column and reducing a load and a transmission time of a pulse signal. SOLUTION: A column decoder section 80-1 for generating a pulse outputs a pulse signal PSI having an optimum pulse width required for selecting a column, outputs this outputted pulse signal PSI to a specific column switch 20-1, and performs a reading operation of data at a high speed by operating this column switch 20-1. Also, the pulse signal PSI having the optimum pulse width is outputted based on an output of the decoder section by a NAND circuit. Further, the pulse signal PSI outputted from the NAND maintains the same pulse width and a logic swing width independently of a position of the column, outputs the pulse signal PSI for a short time, a driving time of a column decoding circuit is shortened and a power consumption is reduced. On the other hand, an inverter is used as a delay circuit, successively delay is performed simply.

Title: Handwritten input tablet
Inventor: KITAZAWA YUTAKA
IPC: G06F3/045
Filed: 1984-08-23
Abstract: PURPOSE:To obtain an accurate handwritten input device by detecting the voltage at both ends of a resistor connected in series to a constant current diode. CONSTITUTION:When a pen 9 is pressed down, a circuit conducts to flow a fixed current (about 1mA) to a constant current diode 10. This current is refered to as I0 and branched into currents I1 and I2 in the direction X according the position where a planar resistance 2 for detection of X direction. The current I2 flows through a resistance 4 for detection of X direction and is increased and decreased quantitatively in the direction X according to the pressed position. Then I0=I1+I2 is satisfied. In the same way, a current I4 flows to a resistance 5 for detection of Y direction with a quantitative change. Thus I0=I3+I4 is satisfied. Here X:Y=I2:I4 is satisfied since the current I0 is fixed. This secures accurate detection of both positions of X and Y axis directions.

Abstract: PURPOSE:To provide the cleaning device which can simultaneously remove the dust on both surfaces of a plate material by providing means for maintaining a negative pressure in a box body and means for driving tackiness rollers in such a manner that the plate material is transported on the tacky adhesive rollers. CONSTITUTION:The negative pressure is maintained in the boxy body and a large quantity of air flows into the box body from the spacings (a) between intermediate rollers 5 and the tackiness rollers 6 and the spacings (b) from the box body when the air is sucked by a blower device, etc., from the lower part of the box body. The parts 8 enclosed by the intermediate rollers 5 and the tackiness rollers 6 attain the negative pressure with the outdoor air and the force by which the glass plate 2 is pressed to the tacky adhesive rollers 6 acts on the glass plate when the glass plate 2 is transported to the box body in this state. As a result, the dust on the rear surface of the glass plate 2 is removed by the tacky adhesive rollers 6. Cleaning rollers 7 are formed of a material having the tackiness power further higher than the tackiness power of the tackiness rollers 6 so that the dust sticking to the tackiness rollers 6 is transferred to these rollers and the always clean tackiness roll surfaces come into contact with the rear surface of the glass 2.
