Title: Sawing method of bent log and sawing equipment thereof
Inventor: ISHIDA KEIICHIRO
IPC: B27B29/02
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To execute the conversion of a log by favorable yielding by taking the maximum warping height position into consideration by a method wherein the log is held at positions, which are obtained by correcting temporary center positions with a formula in response to the maximum warping height position and the magnitudes of the maximum warping height, the top end diameter and the butt end diameter of the log, as actual sawing centers. SOLUTION: In order to saw a bent log, the stepping of a sawing device is determined by estimating the size of a rectangular timber in proportion to the top end diameter on the small diametral end side between the butt ends of the log. Further, a clamping device holds positions, which are obtained by correcting near center positions of one or both the butt ends of the log or temporary center positions with a formula: k1 ×H+k2 ×(D2 -D1 ), in which H is the maximum warping height, D1 is the top end diameter of the log, D2 is the butt end diameter of the log and k1 and k2 are constants. Concretely, k1 =1.0 and k2 =0.5 when H<20 mm under the condition that the maximum warping height position is near the middle of the log; k1 =k2 =0.5 when H>=20 mm under the same conditions as described above; k1 =0.6 and k2 =0.75 under the condition that the maximum warping height position lies near the intermediate between the middle of the log and its butt end or lies near the intermediate between the middle of the log and its top end, as actual sawing centers.

Abstract: PURPOSE:To reduce NOx efficiently by the promotion of the mixture of air and fuel and providing the mixture with uniformity and, at the same time, reduce combustion noises by providing a first jet section which is provided on the upstream side of the burner main body and supplies fuel by jet to the main body of a burner and a silencer chamber in which a section provided on the upstream side of the burner main body opens at a second mixture gas channel and communicates with the discharge port of a fan. CONSTITUTION:A silencer chamber 24 acts as a space for mixing and sends the mixture gas in which uniformity is promoted to a second mixture gas channel 17, and as a result a mixture gas of a low oxygen concentration which is out of the range of combustibility and blown out from a mixture gas blow-out port 18 is supplied to the flame that is formed above a flame port section 15, which makes the combustion reaction of the flame that is formed in a burner main body 14 slow, and the flame temperature falls. The turbulence component and noises that are generated at the time of the rotation of a fan 23 and transmitted to the downstream side reduces the level as a source of vibration exciting by the muffler effect that is determined by the space volume of a silencer chamber 24 provided near the discharge outlet of the fan 23 and the area of the opening in a partition plate 26. As a result the disturbance of the mixture gas that is supplied to the flame are suppressed and the flame is stabilized and the combustion noises that are amplified by the resonance system of the equipment is reduced. With this arrangement it is possible to reduce efficiently the generation of NOx further.
