Title: Produce grader
IPC: B07C5/342
Filed: 1976-01-09
Abstract: 1514054 Detector signal amplification  AMF Inc 9 Jan 1976 [26 Feb 1975] 00772/76 Heading G1A [Also in Division H3]  A detector 23 Fig. 2a provides a weak D.C. signal which is converted by a chopper S3, S4 gated by a first gating signal T 1 , T 2  into an A.C. signal, amplified, 46, 51, 52, and reconverted to D.C. by a synchronous detector S6 controlled by a second gating signal T 4  having a duty cycle not exceeding that of the first gating signal and being variable, whereby the amplification is adjusted. Photodiodes 22, 23, Fig. 1 provide signals representing respectively green and red light components reflected from tomatoes 12, to a colour grader 26 which signals an air-jet valve 30 to blow excessively green tomatoes into a reject stream. Photodiode signals are processed in similar channels, Fig. 2a. The green signal is chopped by electronic switches S1, S2 alternately closed by squarewaves at 500 Hz frequency having alternating duty cycles T 1 , T 2 . After amplification 45, 47, 48 the green signal is reconverted to D.C. by a synchronous switch S5 gated by rectangular waves T 3  having a duty cycle which begins later and finishes earlier than that of T 1 , so as to excise switching spikes which occur at the leading and trailing edges of the A.C. signal wave. The D.C. signal (G) is thus provided at a capacitor C6. The red channel is similar, except that its synchronous detector switch S6 is gated by a rectangular wave T 4  having a duty cycle whose start can be adjustably delayed in relation to T 3 , to produce a pulse of variable width. The resultant D.C. signal (R) at capacitor C7 thus represents, with variable gain, the photodiode 23 output, whereby the relative strengths of the G and R signals may be adjusted. A circuit (see also Division H3) for generating the waveforms T 1 -T 4 , by combining and gating squarewaves derived by binary division 86 from a 16KHz clock generator 85, is shown in Fig. 4, the waves at various stages being shown in Fig. 5. A further circuit Fig. 2b (not shown) combines the R and G signals to provide a delayed (R+G) signal indicating to the rejection apparatus that an object is passing, and a (R-G) signal which inhibits rejection if it is positive, or allows rejection if it is small or negative.

Title: Voltage regulator, its programming-voltage supply method, and bias-current correction method and memory device
Inventor: MACCARRONE MARCO
IPC: G11C17/00
Filed: 1995-01-04
Abstract: PURPOSE: To improve both stability and reliability by using a current mirror, a resistive divider, an amplifier stage, a source follow-up transistor TR and a resistive path connected to a reference potential. CONSTITUTION: A current mirror 3 corrects the voltage drop that is caused by the serial resistance of a bit line where its programming is ready. Then this programming is carried out by giving the voltage which varies according to the current draw of one or plural cells to be programmed to the reference potential that is obtained from reference voltage VPP via a resistive divider 2. A TR MG2 is prepared to hold a resistive path 8 reaching the ground from the programming voltage VP, and the bias current is partly subtracted from an inverted current. This subtraction part is decided by the W/L ratio of a TR contained in the mirror 3. As a result, any offset voltage that is generated on a programming line can be corrected.

Title: Ellipse drawing device and recording medium recording ellipse drawing program
Inventor: SAWADA TOMOHIRO
IPC: G06T11/80
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To draw a tilted ellipse by high operating performance by drawing the ellipse on a screen based on a normally standing square circumscribing a reference ellipse shown on the screen and a set inclination. SOLUTION: An elliptic drawing (reference ellipse) 50 on a read-in base paper is displayed on the screen 5A of a display means. A cross cursor on the screen 5A is operated to draw a normally placed rectangle 51 to be in contact with the drawing 50. The vertical and horizontal directions of the rectangle 51 are detected and contrasted to decide a contrast value and when the contrast value is smaller than a set value (>1), this processing operation is finished. When the contrast value is larger than the set value, the normally placed rectangle is regarded as a normally placed square. The length of the normally placed square is detected. Next, the normally placed ellipse circumscribed about the normally placed square is prepared and is superposed to the reference ellipse.  At this time, inclination for obtaining the ratio of the linger diameter and the shorter diameter of the normally placed ellipse is designated. An ellipse is prepared so as to be inscribed in the normally placed square according to the inclination and the cross cursor.

Filed: 1989-01-06
Abstract: PURPOSE:To decrease the dot defects of the display element so that the presence of the color picture elements themselves are made inconspicuous and the visual display quality is improved by adopting the disposition in which the divided picture elements of the adjacent color picture elements are nested with each other. CONSTITUTION:The color picture elements 1 of three primary colors are disposed as R1, R2..., G1, G2..., B1, B2... which are further divided as 3 pieces of the divided picture elements 2 to R11, R12, R13..., G11, G12, G13..., B11, B12, B13.... These picture elements are disposed in a triangular or inverted triangular shape and order of RGB is repeated in a horizontal direction. The picture elements are disposed to the form in which the divided picture elements 2 of the adjacent color picture elements 2 are nested with each other by inverting the upper and lower postures of the triangular shape at every one color picture element. The display with the remaining picture elements is, therefore, possible even if one of the divided picture elements 2 is defective. The size of defects is a fraction of the number of divisions and the defect is inconspicuous. Visual color mixing and mingling are liable to arise.
