Title: Drilling method of printed circuit board
Inventor: OKANO TOKUO
IPC: B23B47/28
Filed: 1988-01-29
Abstract: PURPOSE:To form holes of high quality and high accuracy efficiently by attaching a presser plate provided with a protruded section on which a hole allowing a drill to pass through is formed on the lower section of a pressure foot and making the hole with the protruded section pressed to a rotary plate and the drill protruded. CONSTITUTION:High pressure is applied to the drilling portions of a print circuit board 2 by the flat surface 3b of small area of a protruded section 3a. This pressure reduces the production of flush edge breaking and cracks. Since the clearance between the hole section 4 of the protruded section 3a and a drill 5 is very small, the run out of the drill 5 is suppressed, as a result the deflection of a hole position in the print circuit board 2 is reduced, and, moreover, the chips produced will not splash on the print circuit board for preventing the surface from damaging. A presser plate 3 is detachable from a pressure foot 1 and periodically exchangeable when the drill is exchanged, and always keeps small clearance for making it possible to quickly cope with a different drill in diameter.

Title: Centroid point operator
Inventor: SUGIOKA TOSHIO
IPC: G06T7/60
Filed: 1985-02-05
Abstract: PURPOSE:To calculate a centroid point without performing the multiplication processing by reading the binary picture data out of a memory to calculate the addition value of the column and row centroids from the contents of the binary picture data and then dividing said addition value by the number of detected picture elements. CONSTITUTION:Both counters 2 and 4 count the clock pulses and send the count values 3 and 5 to a memory 1 for designation of the columns and rows of the memory 1. At the same time, these columns and rows are sent to the columns and row centroid adders 11 and 12 respectively. The binary picture data 8 read out of the memory 1 are sent to a detected picture element counter 9 and adders 11 and 13. Here the counter 9 counts up pictures if included in the data 8. While adders 11 and 13 add the count values 3 and 5 to the column and row addition values 12 and 14 respectively and produce new addition values 12 and 14 to send them to a divider 15. Thus the divider 15 devides both values 12 and 14 by the detected picture element number 10 respectively and obtain the column and row centroid coordinates. Thus the multiplication processing can be omitted for operation of the centroid points.

Abstract: PURPOSE:To provide a device which can change a display screen in accordance with variation of surrounding brightness in driving of a vehicle without degrading discrimination characteristic of a road displayed on a display device and its classification. CONSTITUTION:In a navigation device which guides a driving vehicle by displaying a road map on a display device, when a command for changing a background color of a displayed map is inputted (110:YES), a background color mode corresponding to the command is read (130), when the background color mode is standard, background color data is changed to the initial value (150), when the background color mode is not standard, background color data for darkening the background color more than the initial state is operated based on the initial value of background color data and corresponding to the background color mode (160), background color data used for display is rewritten (170), and a displayed map is changed. Consequently, when a vehicle drives on a dark road, only background of the displayed map can be darkened, and a road map can be made easy to see without degrading discrimination characteristic of a road and a railway and the like constituting the road map.

Title: Tape recorder
Inventor: SHIMADA HIROMICHI
IPC: G11B15/44
Filed: 1985-02-06
Abstract: PURPOSE:To prevent a case where a tape is taken up to a capstan or a pinch roller by controlling the revolutions of a reel motor through a speed control part when the drive of the tape is started at a constant speed so that the motor is revolved at a high speed for a prescribed period of time, then has an optimum revolving speed for the drive of a constant speed after the prescribed period. CONSTITUTION:A speed control part outputs an output signal when the constant- speed drive is started so that a reel motor is revolved by a revolution control part. Then the speed control part controls the revolutions of the reel motor so that the motor is revolved at a high speed to the revolving speed optimum to the constant-speed drive for a prescribed period of time, then the reel motor is set at a revolving speed optimum to the constant-speed drive after the prescribed period. As a result, the reel motor is revolved at a high speed for a prescribed period even though the 4th gear 57 engages the 3rd gear 56 in a forward play mode. Thus the 1st gear 52 is revolved at a high speed and the gear 57 disengages quickly from the gear 56 and engages the 2nd gear 54. Thus, the right reel drive disk is revolved at a high speed. This prevents a case where a tape is taken up to a capstan or a pinch roller.

Title: Spark gap device
Inventor: CHIIMAN AARU PAATERU
IPC: H01T2/00
Filed: 1991-01-23
Abstract: PURPOSE: To provide a small-sized, reliable spark gap device by layering a trigger electrode on a dielectric substrate and covering it with a dielectric layer and forming an anode and a cathode on the dielectric layer so that a spark gap is formed between these anode and cathode. CONSTITUTION: A predetermined potential is maintained between an anode 16 and a cathode 17 by a charging capacitor, and a trigger pulse is supplied to a trigger electrode 12 in adequate time and adequate state. The pulse in the trigger electrode 12 ionizes some of gas atoms in a spark gas 19, and thereby a break-down voltage between both ends of the spark gap 19 is reduced to a potential to be applied between the anode 16 and the cathode 17 or less. When discharge occurs between the spark gaps 19, an energy accumulated in the capacitor is discharged into a load as a high-current pulse with short continuation time. This device 10 is preferable to usage for igniting a fuse of ammunition because it does not use a gas discharge tube, and it is preferable to surround a spark gap 19 by a cover 26 depending upon ambient conditions.
