Title: Current limiting system of circuit breaker
Inventor: KATO KAZUHIKO
IPC: H01H71/12
Filed: 1990-07-04
Abstract: PURPOSE:To increase pole opening speed of contacts at the time of current shutting by generating at least one of drawing force between a fixed conductor stand and a contact arm by magnetic work of electric current, drawing force between a fixed conductor stand and a coupling arm, and a repulsive force of electric current. CONSTITUTION:In the case that large current runs in a circuit breaker owing to a short-circuitting accident, etc., an electromagnetic repulsive force due to the large current at the time of short-circuit is generated between a tilting part 14c of a fixed conductor stand 14 and a coupling arm 12b of a current limiting contact stand 12 and further a repulsive force is generated between a contact arm 12a of the current limiting stand 12 and a movable contact stand 9, so that the current limiting stand 12 is opened at high speed contraclock-wise on a movable center of a pin 17. When the current limiting stand 12 is displaced by electromagnetic force, the direction of electric current running in a cut and stood part 14a of the fixed conductor stand 14 and the direction of electric current running in the contact arm 12 of the current limiting stand agree and pole opening operation of the movable contact 10 and the current limiting contact 11 is further accelerated. As a result, pole opening speed becomes high.

Filed: 1985-08-14
Abstract: PURPOSE:To perform an interference control flexibly at high speed by rearranging and classifying the interference functions of a knowledge base system and providing a processing unit to realize their performance at every basic function, and providing a means which drives the processing unit on a data drive basis. CONSTITUTION:A data input/output function 16 writes fact data in a working memory 11.

Patent JP-H0621471-A (JP)
Title: Semiconductor device
Inventor: TAKENAKA NOBUYUKI
IPC: H01L29/788
Filed: 1992-07-06
Abstract: PURPOSE:To reduce the deterioration of characteristics caused by the formation of an interface level by injecting hot electrons into a floating gate while suppressing deterioration of the oxide film interface caused by a hot hole. CONSTITUTION:A p-n junction composed of a silicon substrate 11 and a buried diffusion layer 12 is biassed forwardly to permit electrons to be infected from the buried diffusion layer 12 to the silicon substrate 11. The injected electrons are accelerated under voltage applied between the silicon substrate 11, and a source 7 and a drain 18 to obtain energy as hot electrons. The hot electrons are moved from the silicon substrate 11 to a gate oxide film 13. Such a hot electron produced owing to a potential difference between the substrate and the source is over a potential barrier between the substrate and the oxide film and enters a floating gate 14. Holes produced are pushed out toward the substrate by a potential between the source and the substrate. Hereby, the oxide film interface is prevented from being deteriorated owing to hot holes.

Title: Architectural plate material
Inventor: MIYAWAKI TADASHI
IPC: E04F13/08
Filed: 1995-06-20
Abstract: PURPOSE: To draw a rule line easily and accurately without use of a scale, etc., when a plate is to be cut at the construction site by printing a graduation at each edge of the bode on its rear surface. CONSTITUTION: At the stage of production at factory, a graduation 3 is printed along each longer edge 2 of the rear surface of a fiber-reinforced cement plate 1. The gradients are tied directly to draw a line, and thereby rule lines can be provided easily. If printing is made so that the zero positions of the graduations 3 are in opposing relationship, the user can use that of the graduations 3 which is more convenient for him to use when the cement plate 1 is placed. If otherwise parallel lines which are parallel with and perpendicular to the edges 2 of the body, are printed at a constant spacing, direct cutting can be made by selecting one of the graph-like lines when no drawing of rule is required. This facilitates the site work execution very much.

Title: Watch with universal calendar
Inventor: MISHIERU GUROOTSUI
IPC: G04B27/00
Filed: 1981-11-06
Abstract: The mechanism comprises a date-disc (8) actuated at midnight by a lever (1) supporting a rotary part (3) with catches (3a) gearing with the wheel (4) of 24 h. The mechanism is so designed that each transition from a date to the next is effected in less than one hour so that the calendar remains still in synchronism with the hours hand, even in the case of the changing of the indication of time-zones. The disc comprises pins (14) controlling at the end of each month through a star-wheel (13) the rotation of a first (17) and a second (20) cam. The cams bear finger-pieces (17a,17b,21) the ones (17a,17b) of the first cam having variable widths according to the different lengths of the months forming bankings for a catch (9) of the lever (1) for hindering the return motion of this lever thus prolonging the duration of the gearing of the rotary part (3) with the disc (8). At the end of February of the normal years a finger-piece (17b) of the first cam (17) juxtaposes itself with a finger-piece (21) of the second cam (20) for causing the transition between the 28th of February and the 1st of March. This finger-piece (21) is missing in the leap years. The mechanism operates in the two directions of rotation of the wheel of 24 h.

Filed: 1990-07-05
Abstract: PURPOSE:To enable a user to previously know a compiling time corresponding to the loaded state of a system at this time by informing a forecasting time required for translating a program to be translated to the user at the time of starting compiling. CONSTITUTION:When the compiling device 2 is started from a user terminal 9, an input part 3 successively reads out a source program 1 and a data part/ procedure part line number totalizing part 4 decides whether each line read out from the source program 1 is a data part or a procedure part and counts up the value of a counter storing the totalized value of the data part or the procedure part in a data part/procedure part counter 5. A compile end time calculating part 6 calculates time required for compiling based upon the number of lines of data part/procedure part of the counter 5 and a calculation model 7 and displays the time on the user terminal 9. Consequently, the user can previously know the compiling time corresponding to the loaded state of the system at this time.

Abstract: PURPOSE:To improve the energy analyzing accuracy to the incident secondary electron by providing an electrode to correct the advancing direction of the secondary electron from the lower side first grid (drawing-out grid) to the upper side second grid (analyzing grid) to inject vertically constantly. CONSTITUTION:On the surface of a sample 13 to be tested, the primary electron beam 12 is irradiated, and to the secondary electron 14 released from the position, the first grid voltage V1 is applied to draw out the secondary electrons 14 upward by the first grid 9, and moreover, an electric field vertical to the advancing direction is applied by a correcting electrode 11 to which a correcting voltage V3 is applied, The secondary electrons 14 are injected vertically to the second grid 10 constantly. In this case, the energy of the secondary electrons 14 receives no influence because the direction of the electric field by the correcting electrode 11 is vertical to the advancing direction, and moreover, the incident angle of the secondary electrons 14 to the second grid 10 is made vertical. An accurate energy analysis can be carried out in the second grid 10 to which the second grid voltage V2 is applied accordingly.
