Title: Method for controlling spray nozzle in burner
Inventor: TAKAHASHI KIYOSHI
IPC: F23N1/00
Filed: 1991-07-26
Abstract: PURPOSE:To obtain the title method wherein a spray nozzle is quickly shifted to a correct position even if there are transmission losses in a transmission line. CONSTITUTION:For a position of a spray nozzle 11 operated in correspondence with the required rate of combustion, the ideal number of steps by a step motor 12, which is a distance between the above-mentioned position and a reference position, is operated. As the amount of hysteresis, a median value of transmission losses in a transmission line 14 between the step motor and the spray nozzle is added to the ideal number of the steps, and thus the number of the steps can be obtained. The number of the steps is used as the number of the steps for feedforward control, and the spray nozzle 11 is shifted. The difference between the actual rate of the combustion and the required amount thereof, which difference is produced again as the result of the above process, is modified by feedback control.

Title: Detection method for directional distribution of finger print image
Inventor: YAHAGI HIRONORI
IPC: G06K9/00
Filed: 1987-08-24
Abstract: PURPOSE:To shorten a time required for processing a finger print by detecting only one side of the contour of a swelling line, and approximating the direction of that contour line as the direction of that swelling line. CONSTITUTION:The shade image of the finger print is binarized and divided in a grid state. Then the plural pieces of picture element constituting each square of the grind are scanned in an X (or a Y) direction and the changing point where the value of the picture element changes from zero to 1 or from 1 to zero is detected. When the changing point is found, the contour line is traced by scanning the unscanned area nearby the changing point and detecting it. When the changing point is not detected nearby it, that point is regarded as an end point of the contour line. Then vectors (a)-(c) are obtained by uniting a start point and the end point, the point where the value of the picture element changes and the vector obtained in that square is compounded. This compounded vector (d) is compared with the directional quantum of eight kinds, for example, and the nearest one is made a directional quantum in that square. Thus the directional distribution of the swelling line of the finger print can be detected in a short time and precisely.

IPC: F16H9/18
Filed: 1994-09-05
Abstract: PURPOSE:To simplify, miniaturize and reduce a cost of a V belt type automatic transmission by dispensing with a grease scattering prevention cover. CONSTITUTION:A weight is manufactured by injecting fiber reinforced resin containing solid lubrication material into a metal mold having a gate 16 composed of a cylindrical cavity 13 and disc shape space. Because the weight is lubricated by the solid lubrication material, a grease scattering prevention cover conventionally used becomes unnecessary.

Abstract: PURPOSE:To sufficiently cope with the fluctuation of a radiation infrared dose, by setting a next stage measured value to a storage value of each stage so as to be discriminated as the same value as a storage value of the previous stage up to a range of >=90% of a previous stage storage value. CONSTITUTION:To a CPU 8, a threshold value which becomes an object to be compared is set in advance, the value of an infrared dose which has been brought to sampling by an infrared sensor 1 is compared with the threshold value, and as a result, in case of exceeding the threshold value, this value is stored as D1. A value of the infrared dose which has been brought to sampling in the next time is denoted as D2 and compared with the value D1 which has been stored in the previous time, and in case of D1>=D2, the processing proceeds to the next stage. Thereafter, the sampling and the measurement are executed up to the D1-Dn values by the same procedure, and at the time of having reached the Dn value, a starting relay 10 for starting an alarm, etc., is operated. In this case, a next stage measured value to a storage value of each stage is set to as to be discriminated as the same value as a storage value of the previous stage up to a range of >=90% of a previous stage storage value. Accordingly, it is possible to cope enough with the fluctuation of a radiation infrared dose, caused by fluctuation of a flame.

Abstract: PURPOSE:To reduce the ejection stroke and also to attain sure ejection by coupling the rear end of a couple of crossed arms A with a triangle fixed cam and engaging an arm B formed to the tip in a way of folding to constitute an ejection lever. CONSTITUTION:An arm B is turned inward and folded by a pin 21 by allowing a triangle cam 22 to turn an arm A around a shaft 27. A couple of crossed arms A are moved by a lever 29 shaken by the turning of a cam 31, the coupling with the triangle cam 22 is unlocked, the arms A are closed around the shaft 27, causing the arm B to be turned outward and opened by the pin 21 to increase the ejecting distance of a magnetic tape cartridge 1. Furthermore, the movement of the lever 29 moves the magnetic tape cartridge 1 which is ejected in a case 2. Since the moving distance (b) of the ejection lever of an ejection mechanism 19 is decreased less than the ejection distance (a) of the magnetic tape cartridge 1, the mechanism itself is miniaturized and also the magnetic tape device is miniaturized.

Title: Recording system for correction contents of source program
Inventor: JIN YASUSHI
IPC: G06F9/06
Filed: 1988-08-24
Abstract: PURPOSE:To reduce the printing cost and to accurately record the correction contents in order to enable a programmer to quickly read a source program by editing and outputting the correction contents of the source program in a print form by limiting only the corrected part. CONSTITUTION:A correction contents extracting means 4 reads successively the uncorrected and corrected source programs out of a source program storing file H1 and checks whether a relevant row is corrected or not for each uncorrected row number by reference to a correction trace table H4. Then the corrected row number, the row changing section, the uncorrected row contents and the corrected row contents are extracted only when the correction of the row is confirmed. A corrected content outputting means 5 for software is operated with a corrected content extracting means 4 in parallel by host computer H. Then the means 4 edits the correction contents extracted for each corrected row into a print form and outputs a correction contents list H5 via a printer. Thus only the corrected parts is edited into a print form and outputted so that the printing cost is reduced and the correction contents can be accurately recorded. Then a programmer can quickly read the correction contents.
