Title: Linear interpolation device
Inventor: TSUTSUI KATSUNORI
IPC: G05B19/4103
Filed: 1987-06-11
Abstract: PURPOSE:To obtain sufficient interpolation accuracy by providing a means storing the present position actual value, storing the round-off error in the present position actual value and reflecting the round-off error stored so far onto a distribution pulse thereby preventing the storage of error. CONSTITUTION:An interpolation distance calculation means 1 calculates an interpolation distance L from a coordinate (XS, YS) of a start point of an interpolation interval and a coordinate (XE, YE) of an end point. An interpolation number of time calculation means 2 calculates an interpolation number of times N within the two intervals of distribution from the interpolation distance L and a given feed speed F. An X axis distribution distance calculation means 3 calculates an X axis distribution distance DELTAX1 being an ideal distance distributed for each one interpolation. The X axis distribution distance DELTAX1 is accumulated by an adder means 4 for each pulse distribution and stored in a storage means 5 as the present position actual value X1. Moreover, a distribution pulse DELTAX2 corresponding to the actual distribution distance outputted from a distribution pulse calculation means 6 is accumulated for each pulse distribution by an adder means 7 and stored in a storage means 8 as a present position integral value X2.

Abstract: PROBLEM TO BE SOLVED: To dynamically conduct frame processing by segmentation and reassembly SAR instruction. SOLUTION: This unit and this method consist of an SAR 1 and a frame processing section 2. The SAR 1 receives an ATM cell stream by lines VC1-VCn and assembles an ATM adaptation layer type 5 frame from ATM cells received by each virtual path VP connection or each virtual channel VC connection. The frame processing section 2 of the post-stage retrieves processing contents of the frame received by the corresponding to VP or VC connection while assembling the AAL5 frame. The SAR 1 has a function of giving the frame, whose assembling is finished, to the frame processing section 2 together with processing contents. The frame processing section 2 can dynamically conduct frame processing on the basis of the processing contents of the frame designated by the SAR 1.

IPC: H01J37/065
Filed: 1990-06-06
Abstract: PURPOSE:To obtain an electron gun device in which no discharge arises by making electrodes in a trapezoidal shape in cross section. CONSTITUTION:The first insulator 2 to electrically insulate and hold a cathode plate 6 to which an electron source is attached, drawing electrodes 3a, 3b to draw electron beams and the second insulator 4 which is used to electrically insulate and hold the drawing electrodes 3 are provided. The electrodes 3a, 3b which are attached to the insulator 4 in a sandwich structure is made in a trapezoidal shape in cross section. As a result, field strength can be greatly reduced near a triple joint portion so that chances to have field emission electrons toward the insulator face is reduced.

IPC: G06G7/163
Filed: 1983-08-12
Abstract: PURPOSE:To attain sufficient dynamic range by providing an amplifier circuit executing multiplication in parallel to attain multiplication at a low voltage. CONSTITUTION:When an input signal VINA is applied to an amplifier circuit 1, a current I1 proportional to the signal VINA flows via a diode D1 and a transistor (TR) Q1 and a current I2 (I1, X1) inversely proportional to the signal VINA flows via a diode D2 and a TRQ2. As a result, an output voltage DELTAV1 converted in logarithmic change is obtained. Then an output voltage DELTAV0=DELTAV1+DELTAV2 is obtained by the voltage DELTAV1 and an input signal VINB at an amplifier circuit 2 and given to an amplifier circuit of the next stage, where DELTAV2 is difference of voltages obtained at each base-emitter junction of TRs Q12 and Q11. An output voltage Vout proportional to X1.X2 is obtained from the voltage DELTAV0 and an input signal VINC at the amplifier circuit of the next stage. Thus, the three amplifier circuits are connected in parallel and activated at a low voltage.
