Abstract: PURPOSE:To correct the deviation of the position of rotation of a detector with an inclined center axis by a method wherein radiation detectors of a scintillation camera are turned about two radiation sources at two separate points on a table of an object to be inspected to determine a deviation value in the position of rotation of plane images of the radiation sources at positions where the detectors are opposed to each other at 180 deg.. CONSTITUTION:Radiation detectors of a scintillation camera are turned about two radiation sources placed at separate two points on a table of an object to be inspected to collect plane images P, Q, P'' and Q'' of the radiation sources. Then. a deviation value is determined by the detectors in the rotation of the plane images of the radiation sources at positions where the detectors are opposed to each other at 180 deg. to obtain an angle phi of inclination of the center axis E of electric rotation with respect to the center axis M of mechanical rotation of the detector from the deviation value and further, an intersection between the center axes of both the rotations.

Title: Memory testing circuit
Inventor: KAMATA TAKEHIRO
IPC: G11C29/00
Filed: 1994-03-08
Abstract: PURPOSE:To reduce signal lines for testings by inputting data from serial data paths A, B to the test input of a selection means while executing the S/P conversion of the data and also simultaneously outputting data from a memory to a path B while executing the P/S conversion of the data. CONSTITUTION:Data from test address, data input terminals 107 (1 to N) and data input terminals 118 by (1 to M) are transmitted to a conversion means 126 via a serial data path 118 by executing the P/S conversion of the data with a conversion means 116. Test data whose S/P conversion is executed by the means 126 are inputted to a memory 101 after being selected with a control signal 2 by a selection means 133. The conversion means 126 executes the P/S conversion of test result data in the memory 101 corresponding to inputted data and then the conversion means 116 executes the S/P conversion of the result data via a serial data path 117. These data are outputted at output terminal 109 (1 to M) to be compared with an expectation value. Thus, in the case the memory having many numbers of input and output signals is directly tested singly from external terminals, the number of transmission signal lines for input data and output results can be remarkably reduced.

Title: Maintenance diagnosing device
Inventor: KATO MOTOYUKI
IPC: G06F11/22
Filed: 1987-02-20
Abstract: PURPOSE:To reduce the application time of a communication circuit set between a maintenance diagnosing device and a maintenance center, by avoiding such a case where the same unrecovered fault information is sent to the maintenance center in many times. CONSTITUTION:When a fault occurs, a logical device 9-n gives the fault information to a log register means 4 via a maintenance diagnosis control means 2 of a maintenance diagnosing device 1. The means 4 writes the received fault information into a memory means 6 together with a flag showing an unrecovered state and starts an automatic reporting means 5. The means 5 transfers the latest fault information to a maintenance center 8 via a communication circuit 7 only when the unrecovered fault information having the same fault factor as the latest information is not included in the information stored in the means 6. While the means 5 processes the unrecovered fault information if detected. Therefore the fault information caused by the same factor are sent just once to the center 8 before they are recovered. As a result, the application time can be reduced for a communication circuit set between the device 1 and the center 8.

The detection signal of the 0-th frame pattern detecting circuit 1 is outputted to the circuit 11. Then the circuits 11-1 (n+1) compare the output of the frame pattern detecting circuit fetched by the fetching pulse received from a frame timing generating part 21 with the output of the frame pattern detecting circuit which is fetched by the precedent fetching pulse. If the equality of this comparison is confirmed, an H level is inputted to an AND circuit 22. Then the circuit 22 outputs a frame pattern detection signal.
