Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To confirm the malfunction of a pressure sensor by sounding an alarm when the frequency analysis value based on the pressure sensor is the specified threshold or more, and outputting the abnormality of the pressure sensor when the output correlation of the pressure sensor and a microphone is less than the specified value. SOLUTION: A microphone 5 is installed on the outside near a combustor 1 of a turbine, and the output of the microphone 5 is sent to a personal computer 4 via an amplifier 6. The output of a pressure sensor 2 is amplified by a first amplifier 3 and sent to the personal computer 4, and the output of the microphone 5 is sent to the personal computer 4 via the second amplifier 6.

Title: Combustion apparatus
Inventor: KAWASAKI YOSHITAKA
IPC: F24C15/32
Filed: 1987-09-30
Abstract: PURPOSE:To permit the improvement of radiating efficiency and the effective utilization of combustion heat, by a method wherein a heat dissipating plate, having an outer diameter larger than the same of a combustion chamber, is provided in an exhaust gas tube, provided above the combustion chamber, at a position capable of covering at least the upper surface of the combustion chamber. CONSTITUTION:Fuel is burnt in a combustion tube 2 and a red-heating part 4 is heated whereby radiation heat is emitted. Heat, not recovered by the red-hot part 4, is discharged to an upper part through an exhaust gas tube 5 or is dispersed from the periphery of a heat permeating member 3 while riding on convection air whereby high-temperature rising air- stream is generated. In this case, multiple stages of heat radiating plates 6 are attached to the periphery of the exhaust gas tube 5 and heat, recovered from exhaust gas, flowing through the inside of the exhaust gas tube 5, is transferred to the heat dissipating plates 6 from the side wall of the exhaust gas tube 5 while heat, retained in rising air stream around the combustion tube 2, is retrieved to the heat dissipating plates 6 while passing sequentially through the opening holes of the heat dissipating plates 6, then, both heats are radiated and dissipated from the heat dissipating plates 6 to the circumference again. Accordingly, radiation efficiency can be improved and the utilizing efficiency of combustion heat can be remarkably improved.

Title: Optical memory incorporating rotary recording medium
Inventor: IKUTA ISAO
IPC: G11B23/03
Filed: 1990-09-19
Abstract: PURPOSE:To effectively prevent flaws of a disk recording face due to collision with the case side by providing a thick projecting part in a position distant from an information recording part. CONSTITUTION:A projecting part 2 is produced in non-information recording part on the inside of upper and lower faces of a disk 1 as one-body forming. Therefore, step coverage is prevented to attain uniform film formation when a recording film is formed by sputtering or vacuum deposition, and consequently, a problem that information of recording, erasing, and reproducing signal are damaged is eliminated. Since the side of the projecting part 2 is detained on the case inside wall surface when the disk 1 is storage in a case, the recording face of the disk 1 is effectively prevented from being flawed by collision with the case side. Thus, the recording face of the disk is prevented from coming into contact with the casing inside to read out information with a high precision.

Abstract: PROBLEM TO BE SOLVED: To increase the efficiency of load conveyance by conveying, basically, the load on a random basis on a main line (main conveyance passage) and merge the load from a sub line (sub conveyance passage) in a short time. SOLUTION: A photoswitch 13 measuring the length of a load on a sub line and a belt feeder conveyor 11 are mounted on respective sub lines 6-9, a photoswitch 5 measuring the interval of the loads on a main line, and a belt feeder conveyor 3 are mounted on the upstream side from the merging position of the sub line of the main line 1. When the length of the load on the sub line is measured, it is determined whether or not the interval of the loads equal to the length of the load on the sub line is present on the upstream side from the merged position of the sub line. When the intervals are present, the loads on the sub line are carried out at these intervals, on the other hand, when the intervals are not present, the loads on the main line are pooled to form the intervals, it is thus possible to carry out the loads on the sub line at the formed load intervals.
