IPC: H04N1/23
Filed: 1991-12-11
Abstract: PURPOSE:To prevent picture quality from being lowered due to the fluctuation of image density without changing the power of a semiconductor laser even when dot size is changed by switching of picture element density, etc. CONSTITUTION:A multi-beam semiconductor laser in which, for example three light emitting parts are provided closely on the same plane is used as a light source of a laser printer, and three spot LS1, LS2, and LS3 are arranged on a photosensitive material so as to be arranged in a subscan direction. The size (d) of one spot is equivalent to the picture element density 600dpi, and the pitch of the spot is set so as to be d/2. The dot size in the subscan direction corresponding to 600dpi can be obtained as the synthesis of the spots by using only the spot LS1, and 400dpi by emitting the spots LS1, LS2, and 300dpi by emitting the LS1, LS3, respectively. Since the size in the main scan direction of the dot can be obtained by controlling light emitting time, it is not required to change the power even when the dot size is changed.

IPC: F02M41/12
Filed: 1993-12-24
Abstract: PURPOSE:To improve time conversion precision of a redundant angle and to provide an accurate target control amount responding to an operation state by a method wherein a pulse time at a target spill period is predicted based on data on pulse times and the coefficients of a rotation fluctuation during a spill two times before a present spill and a preceding spill (an overflow of fuel to a fuel chamber). CONSTITUTION:A ratio between a pulse time approximately simultaneous to a period at which the instantaneous number of revolutions of an engine M1 is maximized after a control period of an actuator M4 two times before a present control period is completed and a pulse time approximately simultaneous to the preceding control period of the actuator M4 is calculated as the coefficient of fluctuation of rotation by a rotation fluctuation calculating means M11. Based on the coefficient of rotation fluctuation and a pulse time approximately simultaneous to a period at which the instantaneous number of revolutions of an engine is maximized after the preceding control period of the actuator M4 is completed, a pulse time in the vicinity of a present target crank angle is predicted by a pulse time predicting means M12. Based on the predicted pulse time, a time of a redundant angle is converted by an angle time conversion means M9. This constitution provides an accurate control amount being a target responding to the running state of an engines.

Title: Wooden-brick fixing structure of laying frame for wooden brick
Inventor: YOSHIMOTO KUNIAKI
IPC: E01C5/14
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To obtain the state, in which wooden bricks are laid stably for a prolonged term, by setting spaces formed in the orthogonal direction to the wood grain direction of the wooden bricks, at a value larger than spaces formed in the wood grain direction. SOLUTION: The laying frame is formed of a frame body consisting of an approximately square-shaped polyethylene resin. Wooden bricks 14 are fixed onto the laying frame by setting spaces in the orthogonal direction to the wood grain directions of the wooden bricks 14 at values larger than spaces in the wood grain directions. Expansion in the orthogonal direction to the wood grain direction is increased by moisture absorption in the wooden bricks 14 by such formation, but the expansion is absorbed by a joint 19, in which a clearance tw1 is set at a large value. Consequently, the wooden bricks 14 are laid on a laying surface by connecting a large number of the laying frames. Accordingly, the expanding sections of the wooden bricks can be let to escape effectively into large spaces and natural expansion and contraction can be conducted, and the laying state, in which the wooden bricks are stabilized for a prolonged term, is acquired.

IPC: G06F3/02
Filed: 1990-11-30
Abstract: PURPOSE:To improve the efficiency of a test by providing such a switching processing where only an irreducible minimum of adequacy check among adequacy checks determined unequivocally for each input data is left at the time of the test. CONSTITUTION:Adequacy check by-pass confirmation 30 is a processing which specifies the by-passing of following adequacy checks C23 and D24 and the processing proceeds to an OK side when the by-passing is specified or to an NG side when not.
