Title: Detecting method of kind of magnetic tape
Inventor: SHIMOTASHIRO MASAFUMI
IPC: G11B5/027
Filed: 1983-04-08
Abstract: PURPOSE:To discriminate the kind of a magnetic tape accurately, by detecting a recorded current optimum for the magnetic tape, by comparing this current with a reference level in accordance with the kind of the magnetic tape, and by discriminating the kind of the magnetic tape based on the comparison. CONSTITUTION:In a recording mode, a counter 18 shifts the counting of the rotation pulse of a cylinder upward with every one rotation of a rotary head 11. The level of a current recorded on a magnetic tape through a digital attenuator 13 and an amplifier 14 is raised in stages with every one field. When the count of the counter 18 reaches a maximum count value which is set beforehand on the basis of the amount of variation of the recorded current, VTR stops recording and rewinds the magnetic tape. Next, in a playback mode, the counter 18 holds a count value corresponding to a recorded current recorded in a field in which a playback level is at the maximum, while a playback signal current is monitored by a maximum value detecting circuit 17. This count value is compared with a count value from a reference level counter 20 by a comparator 19, and the two kinds of magnetic tapes are discriminated on the basis of this comparison.

Title: Motor drive circuit
Inventor: IMAI YASUAKI
IPC: H02P6/08
Filed: 1990-03-14
Abstract: PURPOSE:To shorten start and stop times of a motor and to drive the motor with low power consumption by subjecting a rotational speed control signal to chopper control only during constant speed rotation interval except starting interval of motor. CONSTITUTION:Upon turn ON of a motor, a maximum current 10 flows alternately through coils Cu, Cv, Cw and a rotor is accelerated. At that time, a rotational speed lock signal 7 has High level and a gate circuit 41 is closed and thereby a switching circuit 42 remains in ON state thus bringing the motor into constant speed rotational state in a shortest time. When the rotational speed lock signal 7 goes Low, the gate circuit 41 is opened and the switching circuit 42 chops the rotational speed control signal with the frequency of the oscillation circuit 42 thus feeding current intermittently through the coils Cu, Cv, Cw. A current 12 flows during conducting interval and the average current will become I0.

Title: Diffusion accentuated imaging method and mri system
Inventor: TSUKAMOTO TETSUJI
IPC: G01N33/48
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To make effective use of data length for an area where it is desired to obtain a diffusion accentuated image. SOLUTION: A preparation sequence A is executed prior to a diffusion accentuation sequence B in such a manner that between first and second images where a diffusion accentuated image originates from a difference between them, the difference between pixel values in an area where it is desired to obtain the diffusion accentuated image is not affected by the preparation sequence, whereas a difference pixel values in an area other than the area where it is desired to obtain the diffusion accentuated image is made very small by the influence of the preparation sequence, so that NMR signals from system other than the area where it is desired to obtain the diffusion accentuated image are restrained.  Therefore, the dynamic range of the diffusion accentuated image can be adjusted so that a pixel value in the area where it is desired to obtain the diffusion accentuated image matches the data length of an MRI device. In a displayed image, the fine contrast of the area where it is desired to obtain the diffusion accentuated image can be expressed without being obstructed by areas other than the area where it is desired to obtain the diffusion accentuated image.

Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent stored contents in a reloadable non-volatile memory from being illegally reloaded by program runaway concerning an electronic controller in which a reloading program for reloading the stored contents in the reloadable non-volatile memory is built in at all the time. SOLUTION: Concerning the controller with which a loaded microcomputer performs reloading processing (S300-S330) for reloading a control program in a flash memory according to the reloading program in a mask ROM when reload permission conditions are established (S100: YES), the reloading program is stored with the arrangement of data, with which reloading processing can not be executed as it is, in the mask ROM and the microcomputer changes the reloading program in the mask ROM into original reloading processing enable data arrangement and transfers it to a RAM (S120). The reloading program in that RAM is executed and reloading processing is performed. Therefore, the stored contents in the flash memory are not changed even when the reloading program in the mask ROM is executed because of program runaway.
