IPC: B41J2/52
Filed: 1989-06-15
Abstract: PURPOSE:To attain error spread processing suitable for a multi-value printer capable of outputting a multi-value picture with several gradation degrees from one picture element by using plural threshold levels so as to apply multi-value processing to a data after the processing. CONSTITUTION:A picture data consecutive in the main scanning direction read by a scanner 101 is subjected to gamma correction by a gamma correction circuit 102 and the result is fed to an adder 103. The adder 103 adds the data with an error G of surrounding picture elements to which the processing by a divider 108 is finished and the result becomes an address input to a ROM 104. The ROM 104 according to the address input outputs a 3-bit data for a multi-value code ID' for the result of processing and a 5-bit data for the output of a processing error G'. The multi-value code ID' being the result of processing is inputted to a printer 109, from which a picture is outputted. Moreover, the processing error G' is stored in an error memory 105. The error memory 105, a multiplier 106, an adder 107 and a divider 108 calculate the error quantity to an input picture element.

Title: Liquid separation mechanism in pressure transmission device
Inventor: AI MITSUO
IPC: G01L13/02
Filed: 1977-12-16
Abstract: PURPOSE: To minimize the dispersion of time constants at the time of miximum damping in a simplified and small constitution, by slidably fitting a liquid separation pipe to a through-hole of a connecting rod provided in the main body, and penetrating the connecting rod into this liquid separation pipe.  
     CONSTITUTION: By keeping the difference Δlbetween the length l 1  of the small diameter part 19 of connecting rod 7 and the length l 2  of the liquid separation pipe 17 within 1 to 20 μm, the leak of sealing liquid 16 from the end face of the liquid separation pipe can be decreased to a practically negligible level. In this liquid separation mechanism, the time (t) of the sealing liquid 16 passing through a gap 18 may be expressed as in formula I.Therefore, even if the dispersion of the time constants at the time of maximum damping cannot be minimized by reducing the dispersion of the gap 18 due to the limitation to the precision of processing, the dispersion of the time constants may be made minimized by making the length of the gap 18 sufficiently larger. Thus, without reguiring high precision processing, the lower limit of the time constant may be larger.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To eliminate generation of noise due to variation in the contact position of an elongated hole and a pin between printing time and sheet feeding time. SOLUTION: The positioning pin 9 of a frame 1 and the elongated positioning hole 17 of a supporting plate 15 are formed at such positions as a force F1 acts from a spring 13 to a print head 11 orthogonally to the surface thereof when the pin 9 is located at the side end part of the head fixing face 15a on the inner side face of the elongated hole 17. Since the force F1 is orthogonal to the surface of the print head 11, drag F2 of a platen 3 is parallel with the force F1. Since the contact position of the elongated hole 17 and the pin 9 is not different when printing is carried out and when a sheet is fed even if a force F4 is applied through rotation of the platen 3 when a sheet is fed, noise is not generated.
