Abstract: PURPOSE:To use one color code as a transparent color code and also as a specific color code by providing plural registers and a transparent color code detecting circuit. CONSTITUTION:A register 9 is a one-bit register and 1 or 0 is written by a CPU2. A register 15, on the other hand, is a four-bit register and a color code is written by the CPU2.

Further, an image based upon color codes in a VRAM5, i.e. color codes of specific colors is displayed at the inside of the area 4b. Then, when the register 9 holds 0, zero detecting circuits 12, 13 both enter an enable state and the color codes are processed as transparent codes. Namely, one color code is usable as both the transparent color code and color code of a specific color.

Title: Frequency adjustment for disk piezoelectric ceramic oscillator
Inventor: SATOU RIYOUJI
IPC: H03H3/04
Filed: 1978-08-17
Abstract: PURPOSE:To secure adjustment of the resonance frquency without causing the parasitic vibration by providing several units of the notch at the positions dividing the outer circumference into equal parts. CONSTITUTION:The notches are given to the outer circumference of disk piezoelectric ceramic oscillator 1 utilizing the spreading vibration in the diameter direction in order to give the outer circumference 2-(a), 3-(b) and 4-(c)equal parts respectively.

In case the resonance frequency is reduced excessively, the outer circumference part is polished to increase the resonance frequency again. In this method, a disk piezoelectric ceramic oscillator featuring the desired frequency can be obtained easily and with a high efficiency.

Title: Sheet conveyor
Inventor: HARA YOSHINOBU
IPC: B65H5/00
Filed: 1988-04-22
Abstract: PURPOSE:To prevent a sheet from being smudged because of toner sticking by making the toner stuck to a presser roll contact with a cleaning part and cleaning it up, in a sheet conveyor which conveys the sheet transferred with a toner image in a copying machine or the like to a fixing unit. CONSTITUTION:When a sheet S is conveyed to an interval between a conveyor roller 1 and a presser roll 13, this roll 13 is pushed upward by strength of stiffness in this sheet S, whereby a space part A is formed in space between the back of the sheet S and a cleaning part 3, and both are held in a noncontact state. On the other hand, the presser roll 13 is energized by a surface of the sheet S, pressing this sheet S to a conveying part 4, and thereby conveyability in the conveyor roller 1 is thus improved. At this time, a pressing tooth of the presser roll 13 comes into contact with the surface of the sheet S. Consequently, if the sheet S is one that holds a toner on the surface electrostatically, the pressing tooth contacts with the toner and holds it. Next, when the sheet S is passed through, the pressing tooth is made contact with the cleaning part 3 and cleaned up.

Abstract: PURPOSE:To exactly calculate sales in each pinball stand by providing an accumulating means to successively store and accumulate the maximum value of an operated result by an earnings and expenses arithmetic means which is from the release of the pinball stand by a releasing means and the next release. CONSTITUTION:When a play is started, a counter 3 counts a counting pulse P1 of an out-ball number and a counter 4 counts a counting pulse P2 of a safe ball number. Then, numerical value signals S3 and S4 are outputted. Then, difference between the out-ball number and safe ball number is operated by a subtracting circuit 5 and outputted as a numerical signal S5. When the numerical signal S5 arrives at a stop setting value N, the play is stopped by a stopping signal Sz. However, when a stop releasing signal Sb is outputted, a counter 11 accumulates the numerical value of a memory signal S9 and a maximum value A in the difference between the out-ball number and safe ball number from the output time of an all-clear signal Sa and up to the output time of the first stop releasing signal Sb. Samely, a maximum value B is accumulated by the output of the stop releasing signal Sb from the releasing time up to the next releasing time and a maximum value C is accumulated until the output of a closing signal Sc. Accordingly, the sales can be exactly calculated in each pinball stand.

Title: Power source for electric discharge machining
Inventor: MAGARA TAKUJI
IPC: B23H1/02
Filed: 1985-05-15
Abstract: PURPOSE:To obtain an extremely good-quality and uniform machining surface at all times by providing plural switching elements which alternately repeat on and off operations, and obtaining a machining power source having a stable output characteristic with respect to variation in floating capacitance and floating inductance. CONSTITUTION:The on and off operations of switching elements 9 to 12 are alternately repeated at a high frequency of several MHz by means of a driving circuit 3, causing a floating capacitance 8 to repeat changing and discharging. By setting a proper switching frequency with respect to the time constant of the floating capacitance 8, however, a high-frequency voltage having two times the voltage of a DC power source 1 is generated across poles, i.e., on both ends of the floating capacitance 8, to carry out electric discharge machining. In principle, since the voltage at the part across the poles 6 depends on the voltage of the DC power source 1, the variation in the floating capacitance 8 can be neglected, stabilizing the output voltage. Accordingly, a good-quality and uniform machining surface can always be obtained.
