Title: Gradation display control circuit
Inventor: ISHII TAKATOSHI
IPC: G09G3/20
Filed: 1988-09-14
Abstract: PURPOSE:To make a gradational display where a flicker is suppressed by making frames corresponding to gradation data illuminate among all frames in a display unit. CONSTITUTION:The decoder part of a decoder/encoder 3 decodes phase number data and outputs a phase number detection signal corresponding to the phase number data and the encoder part selects components of the phase number detection signal corresponding to gradations and outputs them as encoded signals corresponding to the gradations. A selector 4 selects encoded signals corresponding to gradation codes and output them as frame modulation video signals FMV. Corresponding dots are turned on or off in each frame according to whether or not the signals FMV are ON or OFF. Consequently, a viewer who looks at a screen notices no flicker and multi-gradation representation is enabled.

Title: Color picture processor
Inventor: OUCHI SATOSHI
IPC: H04N1/40
Filed: 1990-08-31
Abstract: PURPOSE:To improve reproduced picture quality by discriminating a small picture pattern area enclosed by a black character area as the black character area and reproducing the edge and the inner part of a black character in black monochrome. CONSTITUTION:A character area and a picture pattern area are discriminated by output from a color discriminating circuit 12 and a character detecting circuit 11. When a specific picture element which belongs to the small picture pattern area is enclosed by a black character area, since a discrimination correcting circuit 14 discriminates that picture element as the black character area, the black character area is printed in black monochrome by a color printer 10. Accordingly, not only the edge of a black character but also the inner part of it are reproduced in black monochrome. Thus, reproduced picture quality is improved and also the consumption of ink can be reduced simultaneously.

Title: Pulse-width modulating power amplifier
Inventor: ISHII SATORU
IPC: H03F3/20
Filed: 1982-12-27
Abstract: PURPOSE:To obtain an efficient pulse-width modulating power amplifier by utilizing the charge storage time of transistors (TR) in a driving cirlcuit to prevent the driving voltage of an output stage from being biased forwardly at the same time. CONSTITUTION:When a positive signal is impressed to an input and TRs Q1 and Q2 are OFF and ON respectively, TRs Q9, Q3 and Q6 are OFF and TRs Q10, Q4, and Q5 are ON, so charges are accumulated in respective base areas of the TRs Q10, Q4, and Q5. In this case, the gate of a FETQ8 is biased forwardly in the middle of the switching operation of the output stage, but the gate of an FETQ7 is biased reversely and no current flows through the FETQ7, so that no cross current is generated. Thus, both FETs Q7 and Q8 are prevented from being biased reversely at the same time. Consequently, the power loss of each FET is reduced greatly to improve the efficiency.

Title: Detecting system of head position in data memory device
Inventor: MIZOSHITA YOSHIBUMI
IPC: G11B5/596
Filed: 1983-12-08
Abstract: PURPOSE:To enable the head positioning with high accuracy and with a simple constitution by using a circuit which compares the numbers of pulse signals between odd and even servo tracks and detecting the position of the servo head according to the difference output of said comparison. CONSTITUTION:The total number of pulses SU corresponding to position signal pulses SP is proportional to the shift degree of the center position of a servo head 1 toward a servo track 3 from the boundary between servo tracks 2 and 3 under the control of a gate signal SG-1. While the total number of pulses SD corresponding to the pulse SP produced under the control of a gate signal SG-2 is proportional to the shift degree of the center position of the head 1 toward the track 2 of an odd number from the boundary between both tracks 2 and 3. Therefore these pulses SU and SD are counted respectively and a subtraction is carried out between these two count values to obtain a position shift degree of the head 1. In other words, the position of the head 1 can be detected.
