Title: Plastic bottle
Inventor: KAWACHI MITSURU
IPC: B65D21/08
Filed: 1994-05-19
Abstract: PURPOSE:To reduce the recovery cost of a plastic bottle and make its reuse easy by permitting the volume of the plastic bottle to be reduced when it is empty. CONSTITUTION:The body part of a plastic bottle has an expandable and contractible area consisting of a number of circumferential or spiral grooves and each groove consists of the two side parts of different lengths. Each groove has a long side part 1 and a short side part 2 interconnected in an adjoining manner and the length of the short side part comprises 30-95% of that of the long side part. The expandable and contractible area is not expanded largely by a weak force and, only when a strong compressive force is applied in the axial direction, the short side part enters the long side part to cause them to overlap and, only when a strong tensile force is applied, the overlapped part is pulled out to produce a large expansion and contraction.

Title: Engine burning low volatile fuel
Inventor: SAITOU HISANORI
IPC: F02B1/02
Filed: 1985-06-28
Abstract: PURPOSE:To increase the temperature of a highly ignitable fuel to a level just before the ignition thereof, and enable the use of a low volatile fuel such as light oil and kerosene for burning with an engine by raising the preheating temperature of air in a cylinder on the continuation of compression strokes for a plurality of times. CONSTITUTION:With both of suction and exhaust valves 1 and 4 closed, a piston 3 is lowered to a bottom dead center in a cylinder 2. In this compression releasing stroke, air in the cylinder 2 restores its original normal pressure state from a compression state. The whole of air temperature increments used during the compression stroke, however, does not come down with said release of compression and air preheating effect obtained at a primary compression stroke stagnates in the cylinder 2. Consequently, air in the cylinder 2 has higher temperature at the start of the second compression stroke than at the first compression stroke. In view of this fact, a compression ratio is set beforehand so that the maximum preheating temperature of air available in the cylinder 2 will be raised up to a level just before the ignition of a fuel when the second compression stroke has been done.

Filed: 1977-11-30
Abstract: PURPOSE:To ensure the signal process which features the simple arithmetic contents and can increase the picture quality by carrying out the conversion of the picture information in such a way that the picture element density is increased only in the primary or secondary scanning direction. CONSTITUTION:Sampling picture element (a) before process is obtained in the form of output picture element (b) after process.
