IPC: F02M35/10
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent brazing filler metal from leaking from the section where an intake pipe and intake pipe mounting cylinder are fixed. SOLUTION: In order to fix the intake pipe of an intake manifold, the intake pipe is inserted into an intake mounting cylinder 5. Then, a section of a specified length is discriminated by a plurality of slits provided in parallel with the axis as a divided section. A cylindrical caulking tool 13 comprising projections 19 and 20 formed in the external peripheral surface of this divided section is inserted into the insertion section of the intake pipe and intake pipe mounting section. In the next step, a bar-shaped tapered pressing tool 14 is inserted inside the cylindrical caulking tool 13 to relatively advance this pressing tool 14 by a pressing means in relation to the insertion section and broaden the positions for the projections 19 and 20 of the caulking tool 13.  Then the external peripheral surface of the intake pipe is pressed against the internal surface of the intake pipe mounting cylinder 5 by the projections 19 and 20 to fix them due to plastic deformation.

Inventor: HOTSUTA KOUJI
IPC: G01F3/10
Filed: 1981-02-12
Abstract: PURPOSE:To make it possible to maintain measuring accuracy for a long period of time by reducing rotating resistance and improving durability, by providing, in the direction of rotation center, teeth to be cut in pitch curve configuration. CONSTITUTION:In teeth-cutting positions of all the teeth-equipped sections, and in the direction of rotation center to the maximum possibility, and by minimizing variation of teeth-contacting pressure angle, and also by taking care so as not to allow negative to occur, respectively different basic rack teeth are cut. And, for instance, odd-number teeth sections 1'-13' prevent increase in teeth-contacting pressure angle by using cycloid curve, and even-number teeth sections 2'-12' prevent occurrence of negative by using involute teeth. It is possible, by doing so, to provide all of the teeth sections 1'-13' with positive teeth-contacting pressure angle and improve durability by smoothening teeth- contact rotation, and therefore, it is possible to obtain a displacement flowmeter which has less rotation resistance and is able to maintain its measuring accuracy for a long period of time.

Abstract: PURPOSE:To reduce waiting time for weighing by detecting, at the time of weighing aggregate, a storage level in each compartment, changing aggregate of the compartment wherein an empty level is detected to the last of preliminary determined weighing order, and weighing next order aggregate earlier than that. CONSTITUTION:Weighing order of various kinds of aggregate delivered from an aggregate storage bin 1 is determined through an aggregate weighing order determining part 9 in a weighing operation board 7. When plant operation is started, a storage level of a compartment which is determined at the first order out of the compartments 1a, 1b, 1c, 1d of the storage bin 1 is detected. Further, when any of full quantity level meters 2a, 2b, 2c, 2d detects that the storage level is not empty, the aggregate is delivered from the compartment to an aggregate weighing instrument 5 to be weighed. When any of empty quantity level meters 3a, 3b, 3c, 3d detects an empty state, weighing order of that compartment is determined to the last. Storage levels of the compartments 1a-1d are successively detected to judge the empty state.
