Title: Monitoring method of smoke by sound wave
Inventor: AKAI YUKIO
IPC: G01N29/024
Filed: 1982-02-08
Abstract: PURPOSE:To enable a remote monitoring of the height, flow direction and spread range of smoke by measuring time covering from the emission of a sound wave to the arrival of the reflected wave. CONSTITUTION:Transmitters, for example, speakers 31-3n of a sharp directivity,and receivers provided close thereto, for example microphones 41-4n are so arranged in a pair on the ground that transmitting and receiving surfaces of sound waves look upward vertically at intervals of 22.5 deg. corresponding to an angle defined at an equal interval on the circumference with a desired radius centered on the stack, for example, bearings N, NNE, NE, NEE, E.... With such  an arrangement, the height and the vertical spread range of smoke can be  detected continuously when it is unseen or even at night by emitting sound  waves sequentially. In addition, the flow direction and the horizontal spread  range of the smoke can be detected continuously based on the bearings of  setting the receivers which have received the reflected waves and angle ranges  between the receivers which have received the reflected waves.

Title: Method for continuously annealing strip
Inventor: SAKAE KUNIO
IPC: C21D9/56
Filed: 1986-01-31
Abstract: PURPOSE:To reduce the cost and to improve the quality of an annealed product by continuously drawing out part of the atmospheric gas in an annealing furnace, filtering and drying the drawn gas and returning it to the furnace. CONSTITUTION:When a steel strip 1 is continuously annealed in a continuous annealing furnace 2, atmospheric gas contg. moisture from the strip 1 is drawn out of the upper stream side of the inlet side chute part 3 by suction with a circulating pump 11. The drawn atmospheric gas is filtered with filters 12 and dried with driers 13. The regenerated atmospheric gas is fed again into the annealing furnace 2 from the feed hole 16 after the flow rate is regulated with a control valve 14 and a flowmeter 15. Fresh atmospheric gas is fed at the lowest flow rate required to keep the internal pressure of the furnace 2. By this method, the amount of fresh atmospheric gas used can be reduced and the amount of moisture in the atmospheric gas in the furnace 2 can also be reduced, so the quality of the annealed steel strip 1 can be improved.

For this purpose, the shifting distance of the mold in a vacuum furnace and/or the heating temp. of the die to each position thereof, are stored in a computer as a parameter (the temp. T deg.C to the shifting distance of the die). The heating temp. profile as a function of each position of the die in the vacuum furnace together with the withdrawal speed profile of the die, are used as reproducible value in the subsequent casting process.

IPC: G10C3/10
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide the pin plate structure of a piano which can always hold the clamping torque of a tuning pin nearly constant. SOLUTION: A pin plate 3 has plywood structure having longitudinal core veneers 31 and lateral core veneers 32 stacked by turns. A sheet 33 of glass fiber is adhered between a longitudinal core veneer 31 and a lateral core veneer 32 which face each other.
