Title: Adjustment method of rf power for mri apparatus
Inventor: TOKUNAGA YUTAKA
IPC: G01R33/46
Filed: 1991-07-15
Abstract: PURPOSE:To improve adjusting accuracy of a RF power significantly by implementing a pulse sequence by a field echo method in the adjustment of the RF power to set a flip angle at 180 deg. when intensity of an MR signal is at its minimum. CONSTITUTION:For the adjustment of an RF power, a pulse sequence by a field echo method is implemented with a sequncer 8 by the control F of a computer system 6 setting TR longer than T1 of an organic tissue to collect an MR signal. Here, as an object P to be inspected is scanned increasing the RF power bit by bit. the dependence of the MR signal on the RF pulse is almost ¦sintheta¦ when a flip angle theta is given at the three-dimensional polar coordinate of X, Y and Z axes. Thus, in the case of TR and T1, the PF power is varied finely near a point where the intensity of the MR signal falls and rises to measure the intensity of the MR signal. Thus, the flip angle 180 deg. is selected by the RF power that will minimize the intensity of the signal.

Title: Method for driving thermal head in density gradation-type thermal transfer printer
Inventor: MUKODA MINORU
IPC: B41J2/36
Filed: 1986-07-23
Abstract: PURPOSE:To obtain a stable and accurate printing density, by a method wherein, a pulse to be impressed for driving a thermal head is divided into two or more parts, the arbitrary setting of conduction time and non-conduction time is made possible for every part, and the non-conduction time is set at and around the center of pulse impressing time. CONSTITUTION:A drive device for a thermal head 7 according to the invention is nearly similar to the conventional art; the difference is that two timers from among a timer IC 4 are used and the second timer is used for obtaining the density-to-density time similarly to the prior art and the first timer is used for setting non-conduction time during a pulse impressing. Therefore, the time required to obtain the density at the around the center becomes longer by the amount of the non-conduction time; this allows a margin in the operation of the second timer. In this manner, the pulse impressing time becomes longer; however, a stable and accurate printing density can be obtained. Furthermore, a multi-gradation printing can be obtained with ease by setting additional non- conduction time positively.

Abstract: PURPOSE:To make compact the size of vaporization water filter and a cooling fan and enhance a cooling capacity by laying out a spiral vaporization water filter formed by a water retention material in a cylinder-shaped air duct. CONSTITUTION:When a ventilation fan 28 and a motor 50 operate, air is introduced into an air duct 32 from a suction port 38 and the introduced air is supplied indoors from an air blowoff port 40. At the same time, a vaporization water filter 26 carries the air to the blowoff port 40 by way of a carrier belt 52. The vaporization water filter 26 whose hollow shaft section is communicated with a water tank 34, is filled with water. Since the material of the water filter has water retention characteristics, the fin section 44 is so wet that its wettability may be enhanced by the rotation of the vaporization water filter 26. As a result, the air introduced from the air suction port 38 is forcibly brought into contact with the fin section 44 so that the air is cooled by the vaporization of water on the surface and blown off as cooled air.
