Abstract: PURPOSE: To inject molten metal surely at a uniform acceleration by charging the molten metal into an injection sleeve then changing the advance speed of a plunger rod continuously from zero to an arbitrary speed at a uniform acceleration.  
     CONSTITUTION: When molten metal 4 is teemed from a ladle 6 into an injection sleeve 1 and a plunger rod 3 is operated continuously from zero speed successively up to an arbitrary speed at a uniform acceleration, a leading end tip 2 presses the molten metal 4 successively to a sprue 5. At this time, air and the like discharged as shown by an arrow, and the molten metal 4 free from the inclusion of air is injected through the spure 5. According to this method, a good die cast product contg. no air is obtained in a short injection time.

Filed: 1990-06-01
Abstract: PURPOSE:To correct dispersion in the magnetic field caused between magnetic poles due to manufacture accuracy or the like and to adjust a magnetic field to each cathode ray tube by adjusting a magnetic field adjustment core so as to correct an unbalance component caused between the magnetic poles. CONSTITUTION:When a magnetic field adjustment core 1f is moved in a direction IN in a core projection 1j, an equivalent permeability of the core projection 1j is increased and when the magnetic field adjustment core 1f is moved in a direction OUT in the core projection 1j, an equivalent permeability of the core projection 1j is decreased. Moreover, the equivalent permeability is respectively increased/decreased according to the same reason as to a magnetic adjustment core 1g and a core projection 1k, a magnetic adjustment core 1h and a core projection 1l, and a magnetic adjustment core 1e and a core projection 1i. Thus, the strength of magnetic fields 1m, 1n, 1o and 1p and the magnetic field distribution are adjusted. Thus, dispersion in the magnetic field caused between magnetic poles due to manufacture accuracy or the like is corrected and a magnetic field of each cathode ray tube is adjusted.

Title: Magnetic shielding room
Inventor: FURUKAWA HIROSHI
IPC: H05K9/00
Filed: 1988-06-10
Abstract: PURPOSE:To enable a magnetic shielding room for MRI with a small leakage magnetic flux and a small diffusion of leakage magnetic flux especially at an arris or a corner to be obtained by placing a magnetic shielding plate so that the arris part may have a chamfering construction and by providing a joint plate made of a high magnetic permeability at the magnetic shielding plate junction part. CONSTITUTION:A joint plate 1 made of a high magnetic permeability material at a magnetic shielding plate junction part and/or a magnetic shielding plate 3 is placed so that the arris part may have a chamfering construction in a magnetic shielding room for a magnetic resonant imaging device (MRI). The joint plate 1 is provided at a shielding material junction part A which is located at right angle in reference to magnetic flux and is not provided at a junction part B which is located in the same direction as magnetic flux. Thus, magnetic flux flows through the joint plate 1 and does not cause a great magnetic flux leakage. Also, since the arris part is formed so that it has a chamfering construction, leakage magnetic flux around this part is greatly reduced.

Abstract: PURPOSE:To enable to keep the idling speed of an engine always at a desired speed, by correcting the relationship between the idling speed and a displaced position of an intake-air control valve stored in memory sequentially on the basis of the position of the control valve at the time when the idling speed has been stable. CONSTITUTION:A provisionally desired throttle opening T1 is detected by detecting whether load is applied to an engine or not from a water temperature signal (c) and a cooler load detecting signal (d) and calculating a desired idling speed NSET. Then, the actual throttle opening T0 is detected by detecting the actual engine speed Nrpm, obtaining a first correction term T2 for the desired throttle opening from the deviation between NSET and Nrpm, summing up the values of the first correction term T2 in the past, calculating a second correction term T3, summing up the terms T1, T2 and T3, and calculating the desired throttle opening TSET. Here, the quantity of intake air is controlled by giving pulse signals to solenoid valves 12, 13 according to the deviation between TSET and T0, and moving a throttle valve 7 through operation of the valves 12, 13. With such an arrangement, the idling speed can be kept at a desired value in a stable manner irrespective of change in the performance of an engine.

Title: Thinning-out processing system for image data
Inventor: OGUMA YUKIO
IPC: G06T3/40
Filed: 1986-06-18
Abstract: PURPOSE:To prevent a two-dimensional image after thinning-out processing from being much different from an original image by rotating a pattern for the thinning-out processing for every frame of image data when bits of pixel information on the original image are thinned out corresponding to the pattern for the thinning-out processing. CONSTITUTION:An extraction processing part 7 compares image data stored in the 1st holding means 5 with the thinning-out pattern stored in the 2nd holding means 6 to make bits of the same order from, for example, the left correspond to each other and extract only bits corresponding to '1' of the thinning- out pattern, and then shifts the remaining bits to the right or left, thus generating thinned-out data. At this time, a rotation control part 4 rotates the thinning- out pattern held in the 2nd holding means 6 by only one bit for each frame in order. The thinning-out bit pattern is therefore not fixed for all image data and varies in frame units.
