Title: Manufacture of led
Inventor: ITO TAKAYASU
IPC: H01L33/56
Filed: 1989-09-25
Abstract: PURPOSE:To prevent a shift in positions between an LED body and a light emitting chip by a method wherein a guide of a lead frame is fitted into a guide hole of a cavity and the LED body is resin-molded. CONSTITUTION:A guide 7 protruding from an LED body 1 is formed at the head of a lead frame 2, while a guide hole 6 for permitting the guide 7 to be fitted into is provided on the bottom of a cavity of a die in which the LED body 1 is to be resin-molded. The head 7 of the lead frame 2 is inserted into the guide hole 6 provided on the cavity bottom 5 of the die, and resin is injected into the cavity 4 to mold the LED body. That is, since the guide hole 6 has been highly precisely worked on a reference position where the lead frame 2 should be inherently located, the lead frame 2 may not shift nor tilt due to pressure at the time of resin injection, vibration caused during operation and failure in contact. When the lead frame 2 itself is subjected to deformation, it can be corrected and fixed along with a support 8 of a leg. Thus a light emitting chip 3 to be mounted on a lead frame 2 can highly precisely be positioned with respect to the LED body.

Title: Image processing method and its processor
Inventor: TAKEO HIDEYA
IPC: H04N1/409
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To suppress production of overshoot and undershoot in an edge of an image in which local fluctuation in an image signal is hardly received in the emphasis processing of an image signal. SOLUTION: An emphasis coefficient β is set depending on an original image signal Sorg by an emphasis coefficient setting means 15 and an edge part index arithmetic means 12 obtains a variance σ<2> of the original image signal Sorg as an index SE representing an edge. The index SE is converted into a correction coefficient α corresponding to the index SE by a conversion table 13, an emphasis coefficient correction means 14 corrects the emphasis coefficient β into an emphasis coefficient β'(=α×β) by means of a correction coefficient α, and an image emphasis means 16 applies emphasis processing to the image signal Sorg according to equation Sproc=Sorg+β' (Sorg-Sus).  Thus, excess emphasis to the edge part is suppressed and the effect of the variance σ<2> at a flat part is excluded to reduce the effect of local density flctuation.

Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent attack by a coenesthesic sensor and the rampages of illegal remodeling, to provide a fair probability of a jackpot to all of players, to cope with the intentional hitting of the jackpot, and to assure a game parlor's sales. SOLUTION: A plurality of numerical values '0' to '299' are arranged in the form of a ring to constitute a ring-like group of numerical values. When these three hundred numerical values for lottery are sequentially extracted, from the first numerical value '0' to the last numerical value '299' as each of the values is incremented by one, the cycle of using up the ring-like group of numerical values is varied from 2 (msec) to 4 (msec) to 6 (msec) and so on. Thus, when the numerical value '7' for lottery leads to a jackpot, the cycle of the occurrence of a jackpot at lottery of the numerical value '7', i.e., the cycle of using up the plurality of numerical values for lottery, varies every time the ring-like group of three hundred numerical values is used up, resulting in the impossibility of expecting the timing of the occurrence of the jackpot.

IPC: G07D7/00
Filed: 1989-09-28
Abstract: PURPOSE:To realize paper money discrimination preventing the increase of memory capacity by laying down an appropriate discrimination standard for every mode respectively. CONSTITUTION:A pattern signal 23 to be discriminated is evaluated by using the same standard pattern signal in all the modes. Here, in any case, a compared result between the pattern signal 23 to be discriminated and the standard pattern signal is converted into a numerical value, and is given definite calculation. As for a calculated result, it is decided whether it is included in a prescribed range for every mode or not. For this decision, an upper limit value 21 and a lower limit value 22 converted into the numerical values respectively are laid down for every mode. Thus, even though the upper limit value 21 and the lower limit value 22 of different width are laid down for every mode, they can be stored in the memory of the smaller capacity compared with a case where the standard pattern signal is stored respectively.

IPC: B41J29/38
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To improve a maintainability for printing jobs by providing a recording medium for registering printing form control information and a printer panel for selecting, inputting printing control information. SOLUTION: In order to print an existing printing job by using printing form control information already registered, a '2; printing form control information selection' of a control panel is selected at a printer panel, and a printing form control information to be used is selected (B5) by a set number selection panel. Thereafter, the existing printing job is transferred as it is to a printer. The printer takes out the printing form control information registered to a hard disk on the basis of a selected, set printing form control information registration number (B6), and uses as information for controlling the printing job. Since printing form control information not to be used is added because the printing job is an existing one, all of these are replaced with registered form information designated by the printer (B7) and only print data are effectively handled and printed (B8).
