Title: Picture processor
Inventor: FUJISAWA TETSUO
IPC: H04N1/405
Filed: 1988-04-27
Abstract: PURPOSE:To attain the effect of no production of a moire image by providing a means storing a processing error generated by dither processing and a means using the processing error for the dither processing of the succeeding picture element. CONSTITUTION:An input picture element data ID is given to an adder 1. The error correction data generated from the latch 3 by the processing of one preceding picture element and the error correction data of the same location by one preceding line from a FIFO line memory 4 are given simultaneously to the adder 1 and added to the data ID. A general dither processing is applied in the dither processing circuit 2 to form a binary output picture element data ID'. A subtracter 6 obtains a difference between the data ID and ID', gives it as an error to a multiplier 5, a prescribed coefficient is multiplied and the result of multiplication is sent to the latch 3 and the memory 4. Since the error is added to the picture element data of the same location of the succeeding line in the memory 4, the data is stored for one line picture element clock period and sent to the adder 1. Thus, the gradation expression over the limited gradation number is attained.

Abstract: PURPOSE:To make an inner surface of a control valve easily accord with a trochoidal inner circumferential surface of a rotor housing by installing the control valve that opens or closes the high load suction port formed in the rotor housing, and forming the inner surface with a soft material. CONSTITUTION:A rotor 4 is planetarily rotated in a casing 1 while making its apex slidingly contact with a trochoidal inner circumferential surface of a rotor housing 2. In this case, a first ON-OFF valve 13 as a control valve is set up in the high load suction port 5 formed in the rotor housing 2. And, this first ON-OFF valve 13 is rotated by an actuator 11 with a shaft 12 as the center, whereby the suction port 5 is made possible to be opened or closed. Inner surface 13b of the first ON-OFF valve 13 is formed with a soft material. With this constitution, even if the inner surface 13b of the ON-OFF valve 13 is somewhat projected to the more inner part than the trochoidal inner circumferential surface 2a, the inner surface 13b is shaved with an apex seal, thus matches the trochoidal surface 2a.

Abstract: PROBLEM TO BE SOLVED: To provide an ink-jet recording device in which in the case of splitting the channel of a heat into a plurality of groups and dividing them, rewriting of printing data of the groups driven by a driving clock signal that is not held in a printing period is prevented. SOLUTION: Printing data driving the channels of groups A, B are latched in a latch circuit 91 and also printing data driving the channels of groups C, D are latched in a latch circuit 92. When a latch signal 1 is inputted, the latch circuit 91 latchs parallel printing data sent from a serial-parallel conversion circuit 90. When a latch signal 2 is inputted, the latch circuit 92 latchs parallel printing data sent from the serial-parallel conversion circuit 90. Thereby, even when the following latch signal 1 of the latch signal 1 is outputted and the printing data latched in the latch circuit 91 are rewritten, the printing data latched in the latch circuit 92 are not rewritten. Therefore, even if the printing clock signal of the group C or D is a type crossing over the next latch signal 1, printing data for driving the groups C, D are secured and high resolving power is realized.
