Title: Sending method for figure information
Inventor: SHIBATA TOYOHIRO
IPC: G06T1/00
Filed: 1989-12-13
Abstract: PURPOSE:To shorten a display time and to reduce storage capacity by compressing figure information by decreasing the number of coordinates in figures and the number of the figures. CONSTITUTION:When there is figure elements on a buffer (a) at the time of figure information transmission, the same or nearby coordinates are converted into one coordinate to omit coordinates and halfway coordinates where inflection is small and segments and polygonal lines are queued on a buffer (b) by replacing the buffers (a) and (b); when there are the figure elements on the buffer (b), the coordinates of their end points are compared with the coordinates of the start points of the segments and polygonal lines on the buffer (a) to compose one polygonal line of them when the coordinates are same or close each other. The number of coordinates is therefore decreased by integrating a nearby coordinate arrangement. Small inflection becomes a straight line and the number of coordinates becomes small. Plural figures are integrated and the number of the figures is decreased. The figure information is compressed, so the display time becomes short, the storage capacity is reduced, and the transmission time is shortened.

Title: Method of sealing electronic component
Inventor: OKANE MASAAKI
IPC: H01C10/32
Filed: 1988-12-19
Abstract: PURPOSE:To avoid defective components and improve productivity by a method wherein the aperture of an electronic component is covered with an ultraviolet- cured resin film and, after the part of the resin film unnecessary for sealing is shielded, the part of the resin film necessary for sealing is irradiated with ultraviolet rays to cure the part and then the uncured part unnecessary for sealing is removed by solvent. CONSTITUTION:An ultraviolet-cured resin film 2 having an area a little larger than the aperture of a trimmer capacitor 3 is printed on a film 1 such as a PET film. After that, the trimmer capacitor 3 is put on the resin film 2 so as to make its aperture 3a adhere tightly to the film 2. A masking jig 4 is provided under the film 1 so as to be aligned with the outer edge of the aperture 3a. If the rear of the masking jig is irradiated with ultraviolet rays, the irradiated part of the resin film 2 is cured and the non-irradiated part of the resin film 2 is kept uncured. After that, the trimmer capacitor 3 is removed from the film 1 and washed with CFC or the like to remove the part of the resin film 2 unnecessary for sealing. With this constitution, a defect of protruding sealing resin can be eliminated and productivity can be improved.

The non-woven fabrics after use are treated by putting the same into a treating device. The disinfecting and sterilizing effect is better with the higher temp. treatment. The treating device is not restricted in its material and structure, insofar as the device is pressure resistant. Usually, the non-woven fabric is treated by putting water into the bottom of the treating device, feed-charging the non-woven fabrics after use therein and blowing steam of >=100 deg.C under pressurization of >=1 atm.  The non-woven fabrics are dissolved simultaneously with the disinfection by such treatment and when appliances are charged therein, the reuse thereof by sterilizing and disinfecting is made possible.

Title: Clock generating circuit
Inventor: NAKAJIMA AKIO
IPC: H03K3/02
Filed: 1988-12-20
Abstract: PURPOSE:To generate a highly accurate clock signal by outputting one pulse when a constant is sequentially subtracted from an input value and the content of a register becomes less than zero, adding the input value to the register again, and performing subtraction in synchronization with a reference oscillation period. CONSTITUTION:An inputted value T is divided upper-level and lower-level. The lower values are sequentially added in a first adding means 17. When the maximum value is obtained a carry signal is imparted to a second adding means 12, and one is added to the upper value. The result is imparted to a subtracting means 15. The subtracting means 15 sequentially subtracts the imparted values. When the result becomes less than a specified value, a pulse signal is outputted. The output of the second adding means 12 is imparted to the subtracting means 15, and subtraction is performed again. This operation is repeated. Only the 1-subtractor 15 and a B register 16 are operated in synchronization with a reference oscillator 14. Therefore, a reference oscillating frequency can be made high. This way enables not reduction in jittering, but also increase in the frequency accuracy.
