Title: Ignition timing controller of multicylinder internal combustion engine for vehicle
Inventor: NAKANISHI TATSUAKI
IPC: F02P5/15
Filed: 1987-11-11
Abstract: PURPOSE:To refrain a body from vibration by vibrating irregularly an internal combustion engine to prevent the resonance of the engine vibration with the vibration of body when the rotational speed in the expansion stroke in a specified cylinder differs from that in the other cylinder. CONSTITUTION:Idling of an internal combustion engine M1 is detected by a means M2, while the rotational speed of internal combustion engine M1 in the expansion stroke in every cylinder is detected by a means M3. On the basis of the detecting result of means M3 is calculated average rotational speed in the expansion stroke in every cylinder by a means M4. Further, on the basis of detecting result of means M3 is extracted by a means M5 as a problematic cylinder the cylinder giving the lowest or highest rotational speed. When the deviation of the rotational speed in the problematic cylinder from average rotational speed in respective cylinders exceeds a predetermined value in idling of the engine M1, the ignition timing in one cylinder except for the problematic cylinder and cylinders giving same ignition sequence as said cylinder is correctively delayed or advanced by a means 6.

Filed: 1990-10-22
Abstract: PURPOSE:To enable recording having high resolution and gradation on plain paper by forming a region displaying a backing contact angle corresponding to a heating temperature on the surface of a recording body and using a liquid containing a compound displaying acidity or alkalinity in place of a recording agent. CONSTITUTION:A recording body has a surface, a backing contact angle of which is reduced, when it is brought into contact with a liquid under a heated state. A compound having a hydrophobic group in the side chain of a high molecular polymer is employed as a material forming such a surface, and a main chain L and the hydrophobic group R are bonded by a bonding group J. A latent image region on the surface of the recording body is formed by heating under the state in which the surface of the recording body and a contact material are brought into contact, and a liquid containing a compound displaying acidity or alkalinity is fed and attached in the latent image region. Said attached liquid is brought into contact with ink for recording held on the recording body, and a region, in which viscosity and elasticity are changed in response to a picture pattern, is shaped to said ink. The ink is brought into contact directly with a body to be transferred, and shifted, thus acquiring a recording picture.
