Inventor: JIYON EMU ADAMUSU
IPC: A61N1/39
Filed: 1993-03-30
Abstract: PURPOSE: To provide a device for unfailingly detecting the GWD of a heart. CONSTITUTION: This device 30 for eliminating the atrial fibrillation includes first sensors (53 and 52) to produce a first electrical output that has the time of duration virtually equal to that of the GWD detected between the first pair of cardiac positions separated each other, and second sensors to generate a second electrical output that has the time of duration virtually equal to that of the GWD detected between a second pair of cardiac positions separated each other. The space between the second pair of positions is wider than that between the first pair of positions. A microprocessor (60) responds to the first and second electrical outputs in order to give indicating signals showing the generation of the GWD when the time of duration of the second electrical output is longer than that of the first one.  Electrical energy for eliminating the atrial fibrillation is applied to the atrium of the heart.

Title: Digital signature device
Inventor: MATSUZAKI NATSUME
IPC: H04L9/32
Filed: 1989-04-14
Abstract: PURPOSE:To speed up a processing at the time of signing by using such a unidirectional function that the output value when the addition result of two terms is inputted is equal to the product of outputs obtained when the two terms are inputted individually. CONSTITUTION:In a system constituted of terminals which have identifiers without overlapping with one another and a center which generates pieces of secret information characteristic to the respective terminals, only the center has the reverse function of such an open unidirectional function that the output value when the sum result of two terms is inputted is equal to the product of output values obtained when the two terms are inputted individually in secret, and the identifier of each terminal is inputted to the reverse function to generate the secret information characteristic to the terminal. A terminal where a signature is made performs only multiplication by a multiplication part and addition by an addition part in addition to arithmetic by a unidirectional function part and calculation by a hash function part. Consequently, the processing time for signing can be shortened.

Abstract: PURPOSE:To detect an accurate bit error by a test equipment at the local side by sending the number of errors of data transmission from a modulator- demodulator at the local side to a modulator-demodulator at the remote side toward the local side repetitively in a bit speed slower than the data transmission speed. CONSTITUTION:In detecting a test signal, an error measuring section 16 checks whether or not the bit pattern of the test signal sent from a test signal generating section 10 is the same as that of a received signal, and when they are different, the number of errors is counted as the error. A reply code generating section 17 sends repetitively a code representing the same error number among the codes comprising a bit speed slower than t data speed communicated between the modulator-demodulators 1,2 until the next command comes from a control section 20. When the said code is inputted to a reply code reception section 11 of a test device 5 through the modulator-demodulator 2, a communication line 4 and the modulator-demodulator 1, the number of errors is discriminated from the constitution of the received code and the result is informed to a control section 14.

Abstract: PROBLEM TO BE SOLVED: To obtain a tool for collecting serum or plasma that has simple structure and is suitable for mass production by providing a means for closing down the blood inlet side of a blood-filtering unit on the completion of plasma filtering. SOLUTION: A blood-filtering unit is used by fitting a suction nozzle 50 to a nozzle- shaped blood inlet. The nozzle 50 comprises a tapered thin tube, and a base edge part for engaging into the blood inlet is made of polypropylene where a large diameter part with a step is set. The filtering unit is inserted into a vacuum blood sample- collecting tube 60. The blood sample-collecting tube 60 is made of polyethylene telephthalate. On the bottom surface of the blood sample-collecting tube 60, a plug 61 is put, where the plug 61 is made of the polyethylene telephthalate and is fit to the tip opening of the suction nozzle 50 for closing. Blood is put in the blood sample- collecting tube 60, and a suction tool is fitted to the opening. The blood rises in the nozzle due to reduced pressure by a suction tool, and passes through a blood-filtering material while blood cells are also filtered.  Filtered plasma and serum are collected in the space between a polyethylene porous film and a lid body. After that, the filtering unit is pushed down for engaging the tip of the nozzle 50 to the plug 61. Then, the suction tool is removed from the opening.

Abstract: PURPOSE:To improve safety by prohibiting the energizing of a heater while selecting temperature setting by a temperature setting means. CONSTITUTION:When a user selects arbitrary temperature by operating the temperature setting means 14 after inserting a power cord to a receptacle, the energizing of the heater 11 is started, and the temperature of a base 10 starts to rise. After that, a temperature control circuit 13 detects the temperature of the base 10 by a temperature detecting sensor 15, and the temperature of the base 10 is set at a temperature range set with a temperature setting means 14. In such a case, when the temperature setting means 14 is continued to be depressed or a closed state is continued due to a fault such as short- circuit, etc., the temperature setting automatically changes sequentially to (low), (middle), (high), (steam), and again to (off), however, no energizing of the heater 11 is performed until a time when the setting is defined i.e., while the closed state of the temperature setting means 14 is continued. In such a way, the safety can be improved.
