IPC: C10L3/00
Filed: 1978-11-15
Abstract: PURPOSE:One of dimers from butadiene, isoprene or 1,3-pentadiene is added to fuel gases as the effective component to give fuel gases a bad odor sufficient detectable even in low concentration. CONSTITUTION:The Diels-Alder reaction of butadiene, isoprene or 1,3-pentadiene readily gives their dimers respectively. The dimers are added to fuel gases in an amount of about 50 or more ppm.

Title: Ignition timing control method of engine
Inventor: YOKOYAMA NOBUYUKI
IPC: F02P5/15
Filed: 1984-07-06
Abstract: PURPOSE:To minimize a drop in engine output and a worsening of fuel consumption in an automobile being unprovided with a catalytic converter, by using a value to be stored in a read-only memory when a car is not yet acceleratedly driven, but in time of an acceleratedly driven state, another value weightedly averaging the last time value and the ROM value this time. CONSTITUTION:Such an ignition timing value as drawing out output of an engine to the maximum is stored in a read-only memory of a microcomputer 15 in advance. And, when a car is in an acceleratedly driven state, a value which is made up of averaging the value newly read out of a map with the last time value according to a car speed is used. Therefore, the ignition timing value comes to one being somewhat delayed whereby a harmful component in exhaust gases is little in quantity, and a drop in engine output is minimized. And, when the car is not yet in an accelerated state, the ROM value is used as it is, therefore the engine shows its maximum output in consequence. Moreover, since the car is not in acceleratedness, the harmful component in exhaust gases is as negligible as little.

Unnecessary torque distribution control is thus avoided so as to prevent combustion milage from lowering.

Abstract: PURPOSE:To enable to reliably obtain an APC signal even if the reflectivity of the lower end of a semiconductor laser element is set to 1 or near this value by applying part of a laser light emitted from the upper end of the element as a monitoring light to a photoelectric converter mounted on the ceiling of a conductive sealing vessel. CONSTITUTION:A photodiode 7 of a photoelectric converter is bonded to the ceiling surface of a metal vessel 11, and the top of an external lead is connected through a soft metal 13 such as an indium to the opposite surface side to the bonded surface. With this structure, a photodiode 7 receives part of a laser light emitted from the upper end of a semiconductor laser element 6 as a monitoring light, photoelectrically converts it and outputs as an APC signal. Accordingly, it is not necessary to emit the laser light from the lower end for monitoring. Since the vessel 11 is electrically connected to a metal stem substrate 4 by sealing, an electrically equivalent state to the conventional structure for bonding the photodiode 7 directly to the metal stem substrate 4 can be obtained.
