Title: Deterioration diagnosis for lng pump
Inventor: WATANABE AKITOSHI
IPC: G01M99/00
Filed: 1988-06-28
Abstract: PURPOSE:To correctly detect the vibration at various sections of an LNG pump by arranging vibration sensors used to diagnose the deterioration of the LNG pump at multiple bearing sections supporting the rotary shaft of the LNG pump. CONSTITUTION:The major portion of an LNG pump 31 is constituted of a rotary shaft 36 supported by bearings 34 and 35 coupled with multiple casings 32 and 33, a motor 37 rotating the rotary shaft 36, and an impeller 38 sucking LNG as the rotary shaft 36 is rotated. The deterioration of the LNG pump 31 is diagnosed by using vibration sensors. In this case, vibration sensors 1 and 2 are arranged on the casings 32 and 33. Signal lines 3 and 4 are guided to a signal processing unit from the vibration sensors 1 and 2. The vibration at various sections of the LNG pump 31 transmitted to the bearings 34 and 35 is correctly detected without detecting the external vibration not related to the LNG pump 31.

Title: Input device
Inventor: KUSUMOTO HIROTADA
IPC: G06F3/02
Filed: 1995-06-27
Abstract: PURPOSE: To improve operability in both longitudinal and lateral directions by enlarging the lateral dimension of a key for vertical and horizontal inputs (cross key) rather than its longitudinal dimension while considering the operability of a thumb. CONSTITUTION: A cross-shaped key 1 is provided on a casing 2 of a controller as an input device, and a lateral dimension B of the cross key 1 is enlarged rather than a longitudinal dimension A. Concerning this cross key 1, arrows a1 and a2 showing operating positions for the vertical input to a computer, etc., and arrows b1 and b2 showing operating positions for the horizontal input are provided on the upper surface. Then, the controller is operated by manipulating the arrow parts of the cross key 1 with the thumb while taking the casing 2 with the hand of a user. At such a time, a conductor provided on the lower surface of the cross key 1 touches a printed circuit board and the computer judges the directional input operation. With this operation, the thumb moves more widely in the lateral direction than in the longitudinal direction.  Therefore, by enlarging the lateral dimension B of the cross key 1 rather than the dimension A, operability is improved and the erroneous operation of horizontal input can be reduced.

Title: Drum-type apparatus for weft measurement and storage of shuttleless loom
Inventor: SEKI HIDEYASU
IPC: D03D47/36
Filed: 1988-06-30
Abstract: PURPOSE:To prevent the application of abrupt variation of tension to a weft by allowing a weft to freely fly toward a nozzle side against the air flow in an annular space at the top of a drum in weft-insertion and taking out the weft at a speed equal to the winding speed of the weft to a drum in the stage of the length measurement. CONSTITUTION:The tip end at the weft-delivery side of a drum 2 is encircled with a ring-cover 8 to form an annular space 10. A weft y is pressed against a checking part 7 of a rotating drum 2 with an air flow generated in the annular space 10 by a blower 11 and a suction port 12 and is essentially checked by the checking part. Separately, the length of the weft y delivered from a yarn feeder and guided through a feeding guide 14 is measured under winding while contacting the weft to a tapered part 3 of the drum. In the weft insertion, the weft y is pulled by a nozzle from the side of the guide 15, pulled out through a drum storage part 6 against the air flow in the annular space 10 and allowed to freely fly. When the storage part 6 becomes empty, the weft y is checked with a pin 13 and, thereafter, the weft y is subjected to length-measurement and fly at a speed equal to the winding speed of the tapered part 3 of the drum.

Abstract: PURPOSE:To attain quick search, by shifting a pickup by a distance based on a distance data between the radius of the present position and that of the objective position of the pickup, in the reproduction of the disc on which a digital data is recorded. CONSTITUTION:The radius of the disc 140 of the position from the absolute address of the present position of the pickup 142 is calculated, the radius of the disc 140 of the position from the absolute address of the objective position is calculated, and the distance to shift the pickup is decided by obtaining the difference of the both (distance data). The number of pulse of a position detecting signal generating one pulse every time the pickup is shifted and the spot crosses over one track is counted, and when the shift distance of the pickup is equal to the said distance data, the pickup is stopped. In this case, the position detecting signal of the pickup 142 is produced by using the level change of the electric signal generated when the spot crosses actually over the track.

Title: Electrophotographic recorder and positioning thereof
Inventor: KONDO YOSHIHIRO
IPC: B41J2/415
Filed: 1988-06-29
Abstract: PURPOSE:To accomplish recording with high resolution by changing the surface potential of a photosensitive layer irradiated with light, flying off toner by Coulomb's force arising from potential difference between said surface potential and an electrified electrode, and forming a toner image on a recording medium. CONSTITUTION:When the photosensitive layer 4 without the surface potential 5 is irradiated with light of a light source 9 from the back side of a supporting body 1, light carrier occurs, whereby a resistance value in the laminating direction decreases from Rvd to Rvp. Since the surface resistance Rsp hardly changes, Rvp<<Rsp holds. The potential of the photosensitive layer is almost equal to the potential Vb of a back electrode 3, so that the value Vb is selected. If an electrical field arising from potential difference ¦Vt-Vb¦ between the potential Vt and the electrifying electrode 6 is set at a prescribed value or more, Coulomb's force acting on toner 8 becomes larger than its adhesion to the electrode 6, and the toner is separated from the electrode 6 and flies off toward the recording medium 7 to form a toner image. Here, potential difference in the part irradiated with light is higher than circumference, so that the toner separated from the electrode 6 flies off and converges on the medium 7 to record an image with high resolution.

Title: Display method for equalizing characteristic
Inventor: KATO EIICHI
IPC: H03G1/00
Filed: 1985-07-22
Abstract: PURPOSE:To decrease number of elements and to make the thickness of an equalizing characteristic display section by changing a dot position representing 0dB so as to display a maximum characteristic compensation quantity and a minimum characteristic compensation quantity in characteristic compensation quantity of each frequency in dots thereby displaying the characteristic compensation quantity at each frequency. CONSTITUTION:Display elements Dil-Di5 (i=1, 2,...7) in total five are provided by one element at an interval of 3dB at each frequency, for example. In order to increase the characteristic compensation quantity of, e.g., a frequency f3 by 3dB to +9dB, a key on an operating panel is operated. Then the dot position representing 0dB is changed to the 2nd position from the lowest position so as to display the maximum characteristic compensation quantity +9dB and the minimum characteristic compensation quantity -3dB among the characteristic compensation quantity at each frequency. Thus, the number of display elements is decreased and the profile of the equalizing characteristic display section is made thin.
