Title: X-ray image pickup method
Inventor: WATANABE EIJI
IPC: A61B6/03
Filed: 1977-10-12
Abstract: PURPOSE: To obtain precision transmission X-ray images by rotating both or one of the radiation source of fan form X-rays and X-ray detectors about the subject at minute angles and radiating the X-rays twice.  
     CONSTITUTION: In the case of obtaining the transmission X-ray images of the subject 1 with the appratus wherein an X-ray source 5 generating fan form X-rays from a generating point P and a detector 6 consisting of plural detecting elements D 1  thru D n  detecting the same rotate with the subject 1 in-between and arbitrary section images of the subject 1 are obtained; the subject 1 is moved in the direction approximately perpendicular to the spreading direction of the fan form X-rays in obtaining the transmission X-raysimages of the subject 1 and during this time the fan form X-rays are radiated to the subjedt 1 in a pulselike manner. After the radiation of the subject 1 in a desired range is completed, the detector 6 is rotated at a minute angle and the subject 1 is returned in the opposite direction up to the initial position, then the radiation of the second time is accomplished. Hence, the detecting elements are in the positions of D 1  thru D n  in the first time and in the positions of D 1 ' thru D n ' in the second time and therefore the X-ray information for the greater part of the subject 1 may be obtained and the precision transmission X-ray images obtained

Title: Electron gun
Inventor: IKEDA SABURO
IPC: H01J37/06
Filed: 1990-05-11
Abstract: PURPOSE:To uniformly generate a strip electron beam in an electron gun for generating an electron beam for irradiation heating by interposing a heat insulating layer between the end portions of a cathode to support each end portion. CONSTITUTION:Each end portion of a cathode 61 is supported by a supporting device 62 via a heat insulating layer 15 and so little heat is dissipated from each end portion to the device 62 and the temperature of each end portion is hardly dropped and therefore thermoelectrons are uniformly radiated from the cathode 61 and a uniform strip electron beam is generated. A metal material for forming a crucible can thus be uniformly heated and melted and an electron gun for irradiation heating whose deposition efficiency is enhanced is obtained.

Title: Idle rotational speed control device for internal combustion engine
Inventor: ARAMAKI TAKASHI
IPC: F02D41/00
Filed: 1987-05-18
Abstract: PURPOSE:To set a load compensating value during stopping of engine accessory load to a suitable small value by reducing the compensating value of load upon operation of engine accessory load by a feed-back compensating value for an ISC control value. CONSTITUTION:When an engine 1 falls in an idle condition, a control unit 36 computes a feed-back control value for controlling the operation of a flow control valve 11 in accordance with an output signal from a rotational speed sensor 30 so that the idle rotational speed becomes a predetermined desired value. Further, when a cooler is operated as an engine accessory load, a predetermined load compensating value is added to the feed-back control value in response to a signal from a cooler switch 34. At this time, the load compensating value is decreased by a feed-back compensating value in accordance with data of detection of rotational speed for the feed-back control value. With this arrangement, the load compensating value becomes relatively small even during stopping of engine accessory load so as to avoid excessively decreasing the feed-back control value, thereby it is possible to prevent the rotational speed from dropping.

Title: Continuously force exerting device
Inventor: YAMAZAKI YUTAKA
IPC: G05B13/02
Filed: 1989-05-16
Abstract: PURPOSE:To continuously generate a command value in an internal part so as to continuously exert a load by installing a command value correction part which corrects a preceding command value without a halt even in a state when a system waits for the command value. CONSTITUTION:A position command Pr 14 is stored in a position buffer 17, and an arrival judgement part 19 compares it with the feedback value 11 of a position. When it reaches the value of the position buffer 17, the part 19 outputs an arrival signal arr 3, and a minicomputer 1 starts calculating the subsequent command value. During that time, a digital servo device 2 multiplies a speed correction coefficient 6 based on a speed buffer 5 where the preceding command 15 is inputted by the command value correction part 4 and attains switching to a lower side in a switching part 7, whereby it outputs the command as a present speed command 8. Thus, the load can continuously by pressure- added without the halt because a value obtained by multiplying the correction coefficient by the preceding speed command is integrated so as to set it to be the present position command even in the command waiting state by a minicomputer operation time.

Filed: 1981-08-05
Abstract: PURPOSE:To perform automatic tuning correctly under a little frequency of fluctuations of ambient temperature and a secular change, by controlling the oscillation frequency of a variable local oscillator to that of a fixed local oscillator through counting and comparison. CONSTITUTION:The output of a fixed local oscillator 18 and that of a variable local oscillator 15 are supplied to a frequency counting comparator 26 to count and compare both the oscillation frequencies. On the basis of the comparison result, a motor 24 is controlled to equalize the oscillation frequencies of the oscillators 15 and 18 to each other. In this case, only when a changeover switch 19 is placed on the side of the oscillator 18, namely, when the oscillator 18 is connected to a frequency converter 14, the frequency counting comparator 26 is put in operation. Consequently, the comparator 26 performs digital processing to nearly eliminate the influence of temperature fluctuations and a secular change, and when plural fixed local oscillators 18 are provided, or when a frequency synthesizer is used as the fixed local oscillator, automatic tuning to the frequency of either case is performed correctly.

Filed: 1989-05-16
Abstract: PURPOSE:To produce hume concrete pipes free from float and release on the inner surface by subjecting a concrete composition containing a specific amount of Portland cement and a polyethylene glycol having a specific molecular weight to centrifugal molding. CONSTITUTION:100 pts.wt. Portland cement is blended with 0.005 to 5 pts.wt. polyethylene glycol having 106 to 3,800 molecular weight to give a concrete composition for hume concrete pipe. The concrete composition is mixed with a given amount of an aggregate and optionally another admixture and kneaded in the presence of water. The concrete material is subjected to centrifugal molding. In the operation, water in the material is extremely smoothly transferred by the added polyethylene glycol to promote dehydration. Consequently, molding time is extremely shortened and hume concrete pipes free from float and release on the inner surface are obtained at low cost.
