摘要:
An activated carbon adsorbing and desorbing evaporative fuel has pores formed therein with the following rates: a rate of a pore whose pore diameter is smaller than or equal to 20 Å in which butane is apt to remain with respect to a pore whose pore diameter is smaller than or equal to 100 Å is less than or equal to 20%, and a rate of a pore whose pore diameter is greater than 20 Å and smaller than or equal to 25 Å that is effective in adsorbing low boiling point gas components with respect to the pore whose pore diameter is smaller than or equal to 100 Å is between 15 and 25%. An evaporative fuel treatment apparatus has a filling chamber filled with the activated carbon as an adsorbent.

摘要:
A fuel vapor treatment device for suppressing emission of fuel vapor from a fuel tank or the like of an automotive vehicle. The fuel vapor treatment device comprises a casing having a charge port connected to a fuel tank, a purge port connected to an intake section of an engine, and an atmospheric air port through which atmospheric air is introduced. Fuel vapor adsorbing material is filled in the casing. Additionally, an adsorbing material cartridge is disposed in a part of the casing and includes a cylindrical cartridge main body section having a cross-sectional area smaller than that of the casing. Fuel vapor adsorbing material is filled in the cartridge main body section. Air introduced from the atmospheric air port is flowable through the inside of the cartridge main body section to the fuel vapor adsorbing material in the casing.

An image forming system including multiple photoconductors arranged in a line extending in a vertical direction and forming one body as one unit, and multiple development devices and multiple exposure devices arranged on one side of the line of the multiple photoconductors. An image is transferred to a recording medium on an other side of the line of the multiple photoconductors.

This invention is a real-time tracking controller for a standard-path robot that detects a target point in advance, permitting higher-speed work. The robot uses both sensed data and previously taught data to accurately execute its task. Accurate control is obtained using target points corresponding to time intervals. Thus, even if the speed or path is changed during operation, accurate tracing is continuously executed.

A muffler for internal combustion engine houses a catalyst for exhaust gas purification and is provided with an exhaust gas inlet pipe through which exhaust gas from the engine is fed to the upstream side of the catalyst. The exhaust gas inlet pipe includes an inlet pipe section provided therein with a venturi section through which atmospheric air as secondary air is inducted into the exhaust gas inlet pipe. The inlet pipe section is extended in the direction of exhaust gas flow to form an extension pipe section which has a length of at least two times the inner diameter of the extension pipe section, thereby suppressing cutoff frequency at lower levels.
摘要:
An improved process for preparing an impact-resistant chemically blended propylene polymer or copolymer, which comprises the following three steps:(1) a first step of polymerizing propylene containing 0 to 1 mole% of another olefin in the presence of a catalyst composed of (a) a carrier-supported titanium catalyst component containing at least magnesium, halogen and titanium on the surface of the carrier and (b) an organo aluminum compound to form specific crystalline polypropylene;(2) a second step of copolymerizing propylene and ethylene in the presence of the reaction product of the first step and the same catalyst while maintaining the content of propylene in the gaseous phase of the polymerization zone at 65 to 90 mole% thereby to form specific low-crystalline propylene/ethylene copolymer; and(3) a third step of polymerizing ethlene, or both ethylene and propylene in the presence of the reaction product of the second step and the same catalyst while maintaining the content of propylene in the gaseous phase of the polymerization zone at 0 to 15 mole% thereby to form specific polyethylene or ethylene/propylene copolymer.
