A continuous assemblage of pots for raising and transplanting seedlings and a method of manufacturing the assemblage is provided, in which it is possible to extend the length of a link piece without folding an extension portion or arranging a slit, thereby making it possible to handle enlargement of the interval between the planted seedlings stably and reliably.A link piece 3 is formed by folding back both ends of a strip-shaped thin film in the length direction, such that approximately one-fourth of the length of the thin film is folded back onto the same face of the in film at each end, then attaching the folded-back portions to the same face of the thin film with a water-soluble adhesive. The link pieces 3 are disposed in two rows in a staggered arrangement in which the folded-back portions 6 are oriented such that they face the folded-back portions 6 of the opposing link pieces 3. Continuous pieces 8 are formed by using a non-water-soluble adhesive to attach both ends in the length direction of each link piece 3 to the opposing link pieces 3. Individual pots 2 are formed between the opposing link pieces 3. Therefore, it is possible to extend the length of the link piece 3 without folding an extension portion or arranging a slit, as in the conventional continuous assemblage of pots, thereby making it possible to handle enlargement of the interval between the planted seedlings stably and reliably.

An exhaust gas purifying apparatus comprising a first and a second casings having expansion chambers, respectively, a third casing arranged between the first and second casings to form a passage therebetween, an inlet pipe introducing the exhaust gas into the first expansion chamber, and an outlet pipe discharging the exhaust gas from the second expansion chamber, whereby a muffler is constituted. The apparatus also comprises a filter arranged in the third casing to trap particulates in the exhaust gas, and a heater arranged adjacent to the filter on the side of the second expansion chamber to burn the particulates deposited on the filter, to regenerate the filter. A flow control unit, comprising a bypass and a valve therein, is arranged such that the exhaust gas normally flows through the filter and the heater, and when the filter is regenerated, at least a part of the exhaust gas flows in reverse through the heater and the filter. This exhaust gas purifying apparatus is built-in to the muffler.

A multi-cylinder internal combustion engine having a plurality of cylinders, each comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The accumulation chambers are interconnected to each other via a common connecting passage. The opening operation of the accumulation valve is controlled so that the accumulation valve remains opened during the compression stroke. In the first half of the compression stroke, a jet of the combustible mixture is spouted out into the combustion chamber from the accumulation chamber to create a strong swirl motion in the combustion chamber. In the latter half of the compression stroke, the combustible mixture in the combustion chamber flows into the accumulation chamber to accumulate the combustible mixture under high pressure, which is spouted out into the combustion chamber at the next cycle.

An internal combustion engine is provided with an auxiliary piston reciprocating within an auxiliary chamber for generating turbulence in a gas mixture contained within a main combustion chamber. Forward motion of the auxiliary piston causes the injection of a gas into the main combustion chamber through a communicating passageway when the main piston approaches top dead center of the compression stroke.

A continuous assemblage of pots for raising and transplanting seedlings and a method of manufacturing the assemblage is provided, in which it is possible to extend the length of a link piece without folding an extension portion or arranging a slit, thereby making it possible to handle enlargement of the interval between the planted seedlings stably and reliably. A link piece is formed by folding back both ends of a strip-shaped thin film in the length direction, such that approximately one-fourth of the length of the thin film is folded back onto the same face of the thin film at each end, then attaching the folded-back portions to the same face of the thin film with a water-soluble adhesive. The link pieces are disposed in two rows in a staggered arrangement in which the folded-back portions are oriented such that they face the folded-back portions of the opposing link pieces. Continuous pieces are formed by using a non-water-soluble adhesive to attach both ends in the length direction of each link piece to the opposing link pieces. Individual pots are formed between the opposing link pieces. Therefore, it is possible to extend the length of the link piece without folding an extension portion or arranging a slit, as in the conventional continuous assemblage of pots, thereby making it possible to handle enlargement of the interval between the planted seedlings stably and reliably.

A door opening/closing apparatus, which can cause quick and smooth start of movement of a sliding door in an emergency, without any possibility of breakage of the door due to quick movement, so that it can be used reliably and safely. When an operating member is released from its lock, it is pulled along with the sliding door, by a uniform force. To start movement of the operating member, a pushing member mounted on a slidable member is pushed by the spring forces of two coil springs, thus aiding the operation of pushing the operating member and permitting quick and smooth start of movement of the operating member, sliding door, etc. With the screwing of an adjustment screw, the spring force of an adjustment spring is adjusted. The adjusted spring force causes a pushing member to be pushed against a guide member via a pivotal member and a pushing member to effect adjustment of the speed of movement of the operating member for braking action.

An exhaust emission gas control device having a first filter trapping particulates contained in an exhaust gas, and a second filter removing offensive odor components in the exhaust gas. The first filter is a honeycomb type having a cordierite substrate on which .tau.-alumina is coated. The second filter is provided downstream of the first filter, and is formed by an ion-exchange of copper on a synthetic zeolite rich in silica to form copper ions thereon.

An internal combustion engine comprises a cylinder block and a cylinder head. A combustion chamber is formed in the cylinder block and the cylinder head. An accumulation chamber is formed within the cylinder head and communicated with the combustion chamber via an operating valve. The accumulation chamber is disposed adjacent to an exhaust port of the engine and is heat exchangeable with the exhaust port. The operating valve is opened approximately at the time the compression stroke is commenced and is closed approximately at the time the compression stroke is completed. A cap is disposed at the entrance of the accumulation chamber and has a plurality of jets formed thereon. The compressed combustible gas mixture is accumulated within the accumulation chamber, heated by the heat transmitted from the exhaust port and spouted out into the combustion chamber, so that approximately uniform turbulences are generated in the combustion chamber and the flame speed is increased.

Disclosed is an internal combustion engine comprising a combustion chamber and an accumulation chamber which are interconnected to each other via an accumulation valve. The opening operation of the accumulation valve is controlled so that the accumulation valve remains opened during the compression stroke. Fuel is fed into the accumulation chamber to form therein a rich mixture. In the first half of the compression stroke, a jet of the rich mixture is spouted out into the combustion chamber from the accumulation chamber to stratify the inside of the combustion chamber so that the rich mixture is collected around the spark plug. In the latter half of the compression stroke, a lean mixture in the combustion chamber flows into the accumulation chamber to accumulate the mixture under high pressure, which is spouted out into the combustion chamber at the next cycle, in the accumulation chamber.
