Title: Image-forming device
Inventor: OSHITA MASAKAZU
IPC: B41J29/38
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To improve the general purpose performance, in the case that binary image data or multi-value image data are selectively transferred. SOLUTION: An image data bus changeover section 104 selects multi-value image data buses WD0-7 at a multi-value data output or selects a binary image data bus (/LDON) at an binary data output. A synchronization clock changeover section 105 sets a synchronization clock LDCLK to a transmission state at output of multi-value image data and sets the synchronization clock LDCLK to a stop state at output of binary image data. In the case of switching binary image data from multi-value image data, after the binary image data bus is selected from the multi-value image data bus, the clock is switched from the transmission state into the stop state. In the case of switching the binary image data into the multi-value image data, after the clock is switched from the stop state to the transmission state, the binary image data bus is switched into the multi-value image data bus.

Filed: 1989-04-11
Abstract: PURPOSE:To suppress the fluctuation in a painting condition by the posture of a plane and to uniformize a painting condition by forming a bulging part which bulges toward the outside to the side wall of a painting booth in the part to constitute the lateral side of a material to be coated on a stage to lower the flow rate of air flow. CONSTITUTION:A bulging part 16 which bulges toward the outside is formed to a side wall 15 of a painting booth 1 in the case in which the air flow supplied from a ceiling 4 flows alongside a material 2 which is to be coated and is imposed on a stage 11. A throttling effect by the presence of the material 2 to the air flow is, therefore, small and the flow rate of the air along approximately the perpendicular surface forming the lateral side face of the material 2 is lowered. The evaporation of a solvent is inactivated and the concn. of the solid content to be deposited is lowered as the flow rate of the air is lower. The concn. of the solid content to be deposited higher than a horizontal plane is, therefore lowered in general and the fluctuation in the painting condition by the posture of the plane to be coated of the material 2 is suppressed. The painting state over the entire part of the material 2 to be coated is thus uniformized.

Title: Small-sized variable focal length lens
Inventor: MORI NOBUYOSHI
IPC: G02B15/16
Filed: 1988-04-15
Abstract: PURPOSE:To obtain the variable focal length lens of a simple constitution which have an off-axis aberration compensated sufficiently by including a lens group which has two positive lenses arranged while having their low-curvature surfaces opposite each other cross a diaphragm in a 1st lens group. CONSTITUTION:The lenses are arranged symmetrically across the stop and then an aberration is generates so that off-axis luminous flux cancel luminous flux around a main light beam before and behind the diaphragm thereby reducing aberrations generated by the whole front group. Specially, the generation of the distortion aberration is reduced and the outward coma of the comatic aberration which is generated by a front positive lens as to upper luminous flux, for example, before the diaphragm is canceled with the inward coma generated by the positive lens behind the diaphragm. Specially, when the luminous flux is thin, a flare generated at the peripheral part of the luminous flux is eliminated and sufficient compensation effect is obtained. Consequently, the lens system which has its various aberrations compensated with good balance is obtained although the constitution is simplified.
