Abstract: PURPOSE:To restrict a projection of a curved part and to provide a more compact heat exchanger by a method wherein a thermal medium pipe for ordinary piping is comprised of two straight parts having circular section and arranged in parallel to each other and a curved line part of ellipse shape which is integrally formed to be perpendicular to these straight line parts. CONSTITUTION:A thermal medium pipe 1 for ordinary piping is comprised of two straight parts 2 having a circular sectional area and arranged in parallel to each other and a curved line part 3 of ellipse shape integrally formed with these straight line parts with its longer diameter L being perpendicular to these straight lines. The curved line 3 is bent by a bending die 4 and their contacted portions are set with a bending short diameter P. In turn, a heat exchanger 5 is comprised of plate-like fins 6 arranged side-by-side at a specified interval and a thermal medium pipe 7 inserted into the plate-like fins 6 at a right angle thereto. The thermal medium pipe 1 is connected to an end part of the thermal medium pipe 7 so as to form a piping. As a result, a full length size C of the heat exchanger 5 is a sum of a size D of the plate-like fins 6, each of the sizes Aa and Ab of each of the thermal medium pipes 1 and 1b. By using the thermal medium pipe 1, it is possible to get a compact heat exchanger.

Title: Dynamic storage device and driving method therefor
Inventor: KOJIMA MAKOTO
IPC: G11C11/409
Filed: 1987-10-12
Abstract: PURPOSE:To attain the accumulation of high density by setting a precharge potential with respect to a bit line to be a half of a power voltage only by means of bit line vs.potential equalization which is executed at the beginning of device activation even if the storage device is affected with power voltage fluctuation in the middle of standby. CONSTITUTION:At the time of T0 when the storage device stands by, a selection signal phi2 and a raw selection signals phiWL are in low states. On the other hand, a precharge signal phiR is low, a sensitive amplifier driving signal phi1N is high, a signal phi1P is low, and the sensitive amplifier is activated. Either of a BL with respect to bit line and a BL is equalized by the power source, and the other is connected with an earth point, whereby they are charged to respective potentials. Even if power voltage fluctuation occurs at the time of standing by, one of the potentials with respect to the bit line goes to the power voltage VCC and the other to an earth potential. When the storage device is activated at the time of T1, the signal phi1N is set low, and the signal phi1N to high, whereby the sensitive amplifier is once stopped. The potential of the signal phiR at the time of T2 is set to VCC/2 at the time of device activation, and the precharge of the bit line is terminated.

Title: Imaging method by mri stereotaxy
Inventor: MACHIDA YOSHIO
IPC: G01R33/48
Filed: 1987-10-09
Abstract: PURPOSE:To enhance the position measuring accuracy of a lesion part, by setting an large intensity of an inclined magnetic field for reading the MR signal in a pulse sequence at the time of imaging so as to increase the same by several times as compared with that at the time of usual imaging. CONSTITUTION:The image strain caused by the non-uniformity of a static magnetic field is generated in the reading direction (e.g., x-direction) of an MR signal crossing the phase encoding direction (e.g., y-direction) to the spin of the tissue of a patient at a right angle. This image strain DELTAx is inversely proportional to the intensity GR of a reading inclined magnetic field. Herein, in order to enhance the position measuring accuracy of a lesion part when imaging is performed, the intensity GR of the reading inclined magnetic field is largely set, for example, to about several times that at a usual time in order to reduce the image strain DELTAx. At the time of usual imaging not aiming positional measurement, the intensity GR of the reading inclined magnetic field is set small as compared with that to prevent the deterioration of image quality.
