Title: Method of electronically controlling fuel feed
Inventor: FUJIMOTO MASAHIKO
IPC: F02D41/14
Filed: 1984-11-05
Abstract: PURPOSE:To improve fuel efficiency, by limiting forcible feedback control for learning coefficient calculation, to a prescribed period after supplementary fuel supply, to increase the period of fuel thinness control. CONSTITUTION:Under a feedback control condition, feedback control, in which fuel is fed aiming at a theoretical air fuel ratio, is performed. Under a fuel thinness control condition, fuel thinness control is performed so that the ratio of fuel to air is lower than ther theoretical ratio. Forcible feedback control for calculating a learning coefficient is limited to a prescribed period after supplementary fuel feed. After the prescribed period, the feedback control is performed under the normal feedback control condition. The period of the fuel thinness control is thus increased to improve fuel efficiency.

Title: Voice coil for loudspeaker
Inventor: KAWAI YOKO
IPC: H04R9/04
Filed: 1993-09-20
Abstract: PURPOSE:To provide a voice coil for loudspeaker with high reliability by preventing the coming off of bonding from occurring when a sub cone is coupled with the upper terminal of a bobbin.

Title: Method for improving thermal stability of synthetic lubricating oil
Inventor: SUUJII SHIEN HASHI HOO
IPC: C10N20/02
Filed: 1990-09-05
Abstract: A process is disclosed for improving the thermal stability of polyalpha-olefin lubricants by contacting the lubricant with an acidic catalyst for a time and at a temperature sufficient to achieve the skeletal isomerization of the molecular structure of the lubricant. The reaction is carried out preferably on unhydrogenated synthetic lubricants in contact with Lewis acid catalysts. Following the isomerization reaction, the unsaturated lubricant is hydrogenated to produce lubricant with better thermal stability. Surprisingly, when the isomerization reaction is carried out using unsaturated oligomer produced from the oligomerization of alpha-olefins in contact with reduced Group VIB metal oxide catalyst on porous support as starting material the viscometric properties of the lubricant, e.g., viscosity and VI, are not significantly altered, although the thermal stability of the lubricant is substantially increased. The reaction of the present invention may be carried out neat or in the presence of a solvent. Improvements in thermal stability are observed over a wide range of catalyst concentrations. Concentrations of about 10 weight percent are preferred with aluminum chloride catalyst.

Title: Ignition device for pulverized coal and carrier air mixture
Inventor: FUJIWARA NAOKI
IPC: F23Q7/06
Filed: 1986-10-03
Abstract: PURPOSE:To allow a direct ignition of pulverized coal and carrier air mixture without impairing the reliability and durability by applying the concentrated radiation heat of a heat generating body which is disposed at a suitable distance relative to the ignition point of the mixture. CONSTITUTION:The mixture of primary air and pulverized coal is supplied from a fuel pipe 14 to a preheating chamber 21. Meanwhile, a heat generating body 35 is heated, and secondary air 32 is supplied to an air-cooled jacket 33. The air in the air-cooled jacket 33 is heated by the radiation heat of the heat generating body 35, and is supplied to an air box 15 as heated secondary air 36. The thermal energy generated by the heat generating body 35 directly heats the coal/air mixture 30 in part, and its radiation heat is further reflected by a reflecting mirror 31 to be focused on the coal/air mixture 30 for concentrating the thermal energy. This way, the coal/air mixture 30 can be ignited. Since the heat generating body 35 is disposed at distance from the ignition point, chances are small for ashes of coal to settle on it.
