Title: Scanning optical device
Inventor: KAMEYAMA TORU
IPC: G02B7/02
Filed: 1991-05-13
Abstract: PURPOSE:To prevent the deflection of the optical axis of a lens due to the thermal expansion rate by setting each height of the fixed surface of a toric lens made of synthetic resin and the fixed surface of a glass lens on the basis of the thermal expansion rate of the lens and the thermal expansion rate of an optlcal box and allowing each optical axis to coincide even if temperature variation exists. CONSTITUTION:A toric lens 11 which is made of synthetic resin and long in the main scan direction is adhesion-fixed through an installation arm 11a on an installation surface 12c in the upper part of an installation pillar 12b having a height n+n1 from the installation seat surface of an optical box 12. Further, a glass lens 13 which is long in the main scan direction is adhesion-fixed on the installation seat surface 12a behind the optical box 12. The installation position of either the synthetic resin lens 11 or the glass lens 13 is set through the calculation from the thermal expansion rate between the synthetic resin lens 11 and the installation member 12 of the glass lens 13, so that the deflection in the direction crossing at right angle with the optical axis direction of the synthetic resin lens 11 due to the temperature variation and the deflection of the optical axis of the glass lens 13 become nearly equal.

Title: Stratified charging engine
Inventor: ODA HIROYUKI
IPC: F02B17/00
Filed: 1983-07-28
Abstract: PURPOSE:To enable the combustion of an engine to be switched corresponding to a condition of the outside air, by detecting a switching point between the stratified combustion and the uniform combustion by the signal of an exhaust sensor, which detects a rate of excess air, so as to switch the combustion by a stratified fuel supply means and a dispersed fuel supply means. CONSTITUTION:When a supply amount of fuel is controlled, a control means 16, in low and intermediate loads below the first preset level by a load detecting means 17, fully opens a throttle valve 14 so as to hold an intake air amount to a fixed level and supplies only stratified fuel by a fuel supply means 11, performing stratified combustion with a large rate lambda of air. Then the control means 16, if it reaches a point A above a predetermined load, starts supply of dispersed fuel by a fuel supply means 13, and if it further reaches a point B, decreases the stratified fuel, transferring the combustion from the stratified combustion to uniform combustion. Setting this point A below the rate lambda of air of an ignition limit while the point B above the rate lambda of air, in which a smoke is started to be generated, the optimum rate lambda of excess air for the switching point A is detected by the signal of an exhaust sensor 18. In this way, the combustion can be most suitably switched even if the temperature rises and the density of air changes due to high ground moving and/or supercharging.
