Title: Exhaust control device for internal combustion engine
Inventor: ITO YASUYUKI
IPC: F02D41/06
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To control the air-fuel ratio during low temperature operation of an engine in a condition most appropriate for activation of catalyst by carrying out the injection of fuel during respective intake and compression strokes. SOLUTION: A fuel injection volume is computed so that an excess air ratio of a mixture becomes about 1.1 which is effective for early activation of catalyst during cold operation of an engine, and thus computed fuel volume is injected two times during respective intake and combustion strokes, and the portion of the fuel injection volume during the combustion stroke is set to a substantially constant value which is required for creating a burnable mixture stratification while the remainder thereof is used for the intake stroke. Accordingly, the mixture is stratified in a combustion chamber so as to stably carry out stratified combustion, thereby it is possible to early activate catalyst 7.

IPC: B41J29/38
Filed: 1991-07-12
Abstract: PURPOSE:To prevent the print duty from being lowered by the processing time in an image data processor and to extend the life of the whole apparatus. CONSTITUTION:A sequence control part turns a bit 7 of a register reg0 in a command register area in a RAM to '1' when it receives a paper feed start command (print start instruction) from an image data processing part. Then, the sequence control part transfers each register (which stores tray data, etc.) in the command register area including the register to a command buffer area, and adds [4] to the value of a storing address pointer. Subsequently, if an argument of the paper feed start command is 80 hex meaning general printing, a print instruction stack counter is incremented (+1). Thereafter, when the count value becomes larger than the value of a register setting the stack number (number of pages), printing is started in accordance with an instruction block designated by the storing address pointer in the command buffer area.

Title: Lens drive mechanism of variable distribution lighting fixture for vehicle
Inventor: OSHIO HIROHIKO
IPC: F21V5/00
Filed: 1993-07-20
Abstract: PURPOSE:To drive to control a movable lens as well as to make the structure simple and in a small size, by composing the system to sway and displace the movable lens in the direction of the optical axis making a rotating shaft on whose left side and right side edges the movable lens is composed, as a rotating center. CONSTITUTION:A movable lens 9 is swayed and displaced by driving to control an actuator 14, and the lens 9 is moved to a specific position to a fixed lens 6, so as to change over a front side radiating light flux to a 'focused radiating light' or a 'scattered radiating light'. That is, since a parallel light flux from a bulb 5 passing through the reflector surface of a reflector 2 is radiated from the rear side of the lenses 6 and 9, the light flux radiated in front of the lens 6 is focused or scattered by the relative relation of the focus position of a lens step 7 composed by both lenses. Furthermore, since the lens 9 is composed to be swayed and displayed in the direction of the optical axis making a rotating shaft 11 as the rotating center, the number of parts can be reduced, and the laterally separating phenomenon or a one side leaning of the light distribution pattern can be eliminated. Consequently, a small size can be realized as well as the structure can be simplified.

Abstract: PURPOSE:To increase a vertical component to a substrate of an evaporating particle flow by forming a metallic wiring layer through sputtering using a target in which a plurality of ring-shaped insulators are arranged concentrically onto a discoid metallic plate. CONSTITUTION:An insulator 2 to which notches are shaped concentrically is disposed onto a metallic target 1, and sputtering is conducted by a permanent magnet 3 as the component of magnet sputtering and a target constituted of an iron piece 4 as a yoke. In this case, the quantity of evaporation in the thetadirection is represented by length of OA, and the locus of a point A is displayed in a circle. When the insulator 22 is arranged onto the metallic target 21, the target at an angle of A or more is not flown out to the outside because the target adheres on the wall of the insulator. Particles, incident angles of which to a substrate parallel with the target extend over 30 deg. or less, are only flown out as particles flown out from such a target. Consequently, particles are not attached to the upper section of a stepped section, and can be deposited on a bottom section. According to such a method, a film is formed to a connecting hole, thus depositing particles in small film thickness difference with an upper flat section regarding the bottom of the connecting hole.
