Title: Semiconductor circuit device
Inventor: YOSHIKAWA TAKASHI
IPC: H03M1/10
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for preparing a great test vector and to perform the operation test of a digital/analog converter at a high speed by providing a selector for selecting counter output or an address bus by a test mode and specifying the address of a memory and the selector for specifying the data of the memory. SOLUTION: The selector 41 selects the address bus 21 and the counter output 52 by the logic value of the test mode 55 and specifies the address of the memory 10. The selector 42 selects the data bus 22 and the counter output 52 by the logic value of the test mode 55 and specifies the memory write data of the memory 10. Thus, in the case of performing a linearity error test, the need of preparing the test vector for changing an address value and a data value for writing the data in the memory 10 for 2<m> times is eliminated and the time and man-hours for preparing the great test vector are eliminated. Also, since input address value data value are not changed, a high-speed test is performed.

Title: Electrolytic cell for flow coulometry
Inventor: HARA TSUGIYOSHI
IPC: G21C19/46
Filed: 1986-08-04
Abstract: PURPOSE:To exactly measure the concn. of the high-concn. ions to be measured by increasing the contact pressure between a working electrode and current collector and lowering the packing rate of the working electrode. CONSTITUTION:A flexible fiber material is used as the working electrode 9 and is so packed into a working electrode housing container 7 that the ends of the electrode two-folded in a central part 30 come to the part of the current collector 2. The contact pressure between the fibers and the current collector 2 is, therefore, increased by the recovering force generated when the fibers are two-folded. The electrical connection between the electrode 9 and the current collector 2 is thus assured. The pressure difference between the electrode 9 side and the counter electrolyte 8 side is decreased by lowering the packing rate of the electrode 9 and since the pore size, porosity or thickness of an electrolytic diaphragm 1 can be decreased, the conductivity of the diaphragm 1 is increased. The electrolytic current to flow between the electrode 9 and the counter electrode 4 therefore increases, and the concn. of the ions to be measured even in a high-concn. liquid to be inspected is exactly and quickly measured.

IPC: G01T1/164
Filed: 1983-09-30
Abstract: PURPOSE:To optimize linearity correction and energy correction and prevent linearity, etc., from sacrificing for nonuniformity correction by making the nonuniformity correction after executing the linearity correction and energy correction. CONSTITUTION:When the low-order seven digits of information stored in an address to which a random number generating circuit 6 outputs a random number of, for example, seven digits at random become smaller than the random number, a comparing circuit 7 supplies ''1'' to a timing signal generating circuit 8, and the most significant digit ''0'' is supplied from an nonuniformity correction memory 5 to put a hold and output circuit 4 in operation. An output circuit 3 generates position signals X' and Y' and an unblank signal and then the hold and output circuit 4 outputs the same position signals X' and Y' and unblank signal a specific time later. The probability that the low-order seven digits of information output successively are smaller than the random number corresponds to the ratio of the degree of nonuniformity appearing at a low side, and the position signals X' and Y' and unblank signal are added nearly according to the probability. The count number C of the position signal X' and Y' and unblank signal after the nonuniformity correction mentioned above is equal to a mean value M at every position.
