Title: Image processing device
Inventor: SOFUE IKUO
IPC: H04N1/40
Filed: 1985-04-24
Abstract: PURPOSE:To reproduce a half tone having a picture quality by constituting a threshold matrix so that the variation of the number of recording dots against the level variation of an image data becomes non-linear. CONSTITUTION:The matrix is the dither pattern matrix of 8X8 dithers, two black dots corresponding to slice levels 1-6 exist, respectively, four black dots corresponding to slide levels 7-10 exist, respectively, and six black dots corresponding to slice levels 11-16 exist, respectively. As the slice level (input picture quality level) becomes higher, the number of increase of the black dots becomes large, and in case when the image data of a prescribed density is inputted, as the density becomes higher gradually, the increase rate of the black dot becomes higher. The number of increase of black dots is made large against the variation of the slice level, therefore, even if the cause of its distortion exists in any of a read system and a recording system, the distortion can be corrected exactly.

Title: Check system for control memory
Inventor: INAUCHI HIDEYOSHI
IPC: G06F9/22
Filed: 1987-04-10
Abstract: PURPOSE:To improve the reliability of a check system for control memory by realizing the switching of the processor working state between a normal mode and a patrol mode, producing repetitively and forcibly continuance instructions in a patrol mode to scan the reading of a control memory, and carrying out a patrol diagnosis. CONSTITUTION:When a normal mode is set, a multiplexer 7 selects an operation field 4 to apply it to a sequencer 2 and the sequencer 2 performs an action designated by the field 4. While the multiplexer 7 selects a continuation instruction and applies it to the sequencer 2 in a patrol mode. Then the sequencer 2 produces an address to give access to a position following the position which received access immediately before a control memory 1. Then the period of the patrol mode is continued for the reading scan of the memory 1 and the patrol diagnosis is carried out. As a result, an error area is cleared before shift to the normal mode and therefore the chances where the errors are detected when a microprogram is executed can be extremely decreased.

Title: Detecting method for velocity of dc motor
Inventor: KURAKAKE MITSUO
IPC: G01P1/10
Filed: 1981-06-09
Abstract: PURPOSE:To detect an actual velocity of a DC motor by conducting an operation for preestimation of a present actual velocity according to the characteristic formula of the DC motor by using a past armature voltage instruction, a past armature current and a past actual velocity every time when an interrupt signal of a constant cycle is generated. CONSTITUTION:FF402 is set by a pulse Pa generated from a pulse generator 400 and is reset by a velocity operation end signal OPEN generated from a processing unit 405. An interrupt pulse generating circuit 403 generates a velocity operation interrupt pulse ITP of a constant cycle. When the pulse ITP is generated at a time, the unit 405 senses the state of setting of FF402. When FF402 is not set, the unit 405 executes an operation of a prescribed formula by using a past detected velocity v(k-1) and past armature currents i(k-1), i(k-2) and i(k-3), as well as past armature voltage instructions e(k-2) amd e(k-3), all of which are stored in a data memory 405c, and thereby preestimates the velocity of rotation v(k). Then, the difference between the same and an instructed velocity VD is determined, and based thereon, an ignition instruction TIC is delivered.

Title: Television precise offset carrier system
Inventor: YASUSATO SHIGEO
IPC: H04N7/00
Filed: 1983-05-19
Abstract: PURPOSE:To obtain high-level picture quality by the synergetic effect between high stability and synchronization by stabilizing highly and synchronizing an offset carrier frequency and the field frequency of a video signal through rubidium oscillators, frequency synthesizers, and frame synchronizers. CONSTITUTION:The frame synchronizers (FS) 1d and 1e in a center 1 write temporarily and read video signals in and out of incorporated memories with a write synchronizing signal, so even when video signals which differ in synchronism are inputted, the FSs outputs video signals containing a substituted reference synchronizing signal, which is utilized to synchronize field frequencies of adjacent stations of the same channel. The video signals are radiated as radio waves from broadcasting machines of respective network stations 2 and 3. The rubidum oscillators 2d and 3d and frequency synthesizers 2c and 3c are installed in the stations to make carrier frequencies of radiation precise primarily. The field frequency is made precise secondarily. Consequently, visual beats due to a shift of the carrier frequencies of two stations from a specific offset frequency and a shift of a television in field frequency are not caused even in a radio wave interference area.

Title: High efficiency power supply
Inventor: YOKOYAMA YASUYUKI
IPC: H02M3/155
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a high efficiency power supply easy to handle and having high efficiency realized easily over a wide load range. SOLUTION: Each gate signal to main FET's 2 and 3 is shifted by a power supply controller 1 when the gate signal is generated as an output. A large low-speed FET 3 is switched while the small high-speed FET 2 is turned on. Then, a switching loss is not caused at the large FET 3, and there is only a small switching loss caused by the small FET 2 switched at high speed. Since the on-time of only the small FET 2 has a small ratio in all the on-time, an on-resistance loss can be reduced by means of low on-resistance of the large FET 3. In this way, the switching loss and the on-resistance loss can be reduced in a wide load range, and high efficiency can be realized.
