Title: Mr imaging device
Inventor: IIJIMA NAOTO
IPC: G01R33/44
Filed: 1993-07-31
Abstract: PURPOSE:To make it possible to obtain a picture image having an equal contrast to that obtained when an MTC pulse is added to all of the image pickup sequence, by adding the MTC pulse to only a part of the image pickup sequence, thereby controlling a temperature rise due to RF heating. CONSTITUTION:It is the data disposed in the central part B of a live data space to control a reconstituted picture image, without an influence of data disposed at end portions A, C. Since an MTC pulse 3 is turned on only for a period b, data with new information by the MT effect added are only the data disposed in the central part B. So, though the MTC pulse 3 was not added for all the periods repeated n-times, a picture image having an equal contrast to the case where the MTC pulse 3 was added to all the periods repeated n- times can be reconstituted. The irradiation of the MTC pulse 3 is limited for the period b, so that generation of total human fever due to the RF heating can be held low.

IPC: G01R19/00
Filed: 1991-05-15
Abstract: PURPOSE:To measure a direct, current high voltage in the contactless manner and non-rotating state by detecting the Coulomb's force acting between an electrode to which the direct current high voltage is applied and a detecting electrode as the change of the weight of the detecting electrode, measuring the same by a scale and operating. CONSTITUTION:Before a voltage is started to be measured, tone weight of a detecting electrode 3 is measured by a scale 5. The measuring value is input to a zero point correcting circuit 6. When a voltage from a direct current high voltage source 1 is applied to an electrode 2, the Coulomb's force based on the voltage of the source 1 acts between the electrodes 2 and 3, so that the electrode 3 is attracted toward the electrode 2. The force acting to the electrode 3 at this time is weight value of the electrode 3 is subtracted from the input value. The operating result is the Coulomb's force. The result is sent to an operating circuit 7, and a square root is operated. The operating value of the circuit 7 is proportional to the voltage of the power source 1. The operating value is displayed by a voltage display 8.

Title: Line traffic reduction method
Inventor: TSUCHIIDA TAKUO
IPC: H04L12/40
Filed: 1993-08-24
Abstract: PURPOSE:To reduce a line utility cost by comparing a destination identification number with a stored number at each transfer of an Ethernet frame and allowing a terminal equipment to receive data only when the both are matched. CONSTITUTION:When an Ethernet frame A is sent from computers 2, 3 on an Ethernet network to a personal computer 1 via a line 14, a filter 19 in a MAC bridge 4 compares a destination Ethernet address and an Ethernet address stored in the personal computer 1 based on the frame A. The frame A is circulated on a line only when both the addresses are matched and received by the personal computer 1. Thus, data independently of the personal computer 1 are not sent to the line 14, in which traffic is reduced. Thus, the utility efficiency of the line 14 is improved and the effective transfer speed of data communication to a remote terminal equipment is increased.

Title: Drive system of switched linear array vibrator
Inventor: KITAMURA TOORU
IPC: G01S7/523
Filed: 1982-11-30
Abstract: PURPOSE:To obtain a sound line generated at a pitch half the pitch of a vibrator in such a state that the sound lines of directionality and display are coincided without generating the difference in the sensitivity of each transmission reception wave, by a method wherein the numbers of vibrators to be driven are always same and one or odd numbered central vibrators are energized or not. CONSTITUTION:Eight continued vibrators 1-8 are subjected to phase driving [energized in delayed time distribution so as to form a wave surface (a)] to obtain a sound line A and eight vibrators 1-4 and 6-9 are subsequently subjected to phase driving so as to form a wave surface (b'') to obtain a sound line B''. As mentioned above, linear scanning is performed while driving is successively shifted. By this drive system, sensitivity difference is not generated because the vibrators are always driven at every eights and the non-coincidence of the sound line during scanning and the sound line related to display is not generated. In this case, this drive system is simultaneously performed not only during transmission but also during reception.
