Title: Production of polyfluoropropionic acid and its acid halide
Inventor: MORIKAWA SHINSUKE
IPC: C07C53/50
Filed: 1993-02-24
Abstract: PURPOSE:To obtain the subject compound useful as intermediates for various catalysts, agrochemicals, pharmaceuticals, lubricating oils, etc., on an industrial scale in high yield at a low cost by oxidizing dichloropentafluoropropane with oxygen under heating in the presence of a small amount of water. CONSTITUTION:An autoclave is charged with a dichloropentafluoropropane (e.g. 3,3-dichloro-1,1,1,2,2-pentafluoropropane) and a small amount of water and heated to 260 deg.C. Oxygen is introduced into the autoclave to 40kg/cm<2> pressure and maintained for 30 min to effect the thermal oxidation reaction. After the reaction, the content of the autoclave is collected in a trap cooled with liquid nitrogen. The trap is dipped in a dry ice-ethanol bath to remove the unreacted oxygen and the produced hydrochloric acid and obtain the objective polyfluoropropionic acid and its acid halide useful as intermediates for various catalysts, agrochemicals, pharmaceuticals, lubricating oils, etc., in high yield. The selectivities of pentafluoropropionic acid and pentafluoropropionic acid chloride attained by the process are 10% and 85%, respectively.

Title: Method for detecting shaft crack by test
Inventor: UIRIAMU ETSUCHI MIRAA
IPC: G01M99/00
Filed: 1990-03-09
Abstract: PURPOSE: To recognize presence of a crack on a pump shaft by processing/ analyzing the result of vibration test applied to an actual shaft with the use of an analysis model for a sample shaft. CONSTITUTION: An intrinsic vibration frequency of a shaft system and its shape are calculated (64) with an analysis model 62 for a shaft system, and the model is modified (66) while a presence of crack is assumed at an axis direction position where crack occurrence is possible. With the use of the modified model, an intrinsic vibration frequency and a mode shape for a newly assumed shaft system are calculated (68). The actually measured intrinsic vibration frequency for a pump shaft system is obtained by, with the use of an electromagnetic agitator 70, adding a radial excitation force to a standing pump shaft 42 through a beam material 72 and a load cell 74. The vibration response of the shaft to an excitation force is measured with an accelerometer 76, and then processed with a fast Fourier conversion analyzer 78, for obtaining a vibration number response function 80.  Then, the actually-measured intrinsic vibration frequency is compared to an intrinsic vibration frequency of a newly assumed shaft system which was calculated from a modified analysis mode, so that presence of crack on the shaft 42 and its scale are recognize (82).

Title: Water level detector
Inventor: YAMAZAKI TOSHIO
IPC: G01F23/16
Filed: 1984-03-27
Abstract: PURPOSE:To detect the change in water level in a broad range continuously, by moving a magnetic body in and out of a coil in response to the change in water level in a water tank, changing the inductance of the coil, and thereby detecting the change in water level. CONSTITUTION:Water is put in a water tank 1. Until the time the water reaches a certain water level, the sum of the weights (sum of the dead weights) of a magnet 20, a magnetic fluid 21, a spring 23 and a pressure piece 24 is larger than the pressure of air 7. The magnet 20 is contacted with a stopper 19b. When the water exceeds a certain level, the pressure of the air 7 overcomes the sum of the dead weights, the magnet 20 moves upward, the magnetic fluid 21 is moved and the inductance of a coil 22 is changed because the magnet 20 enters in the inside of the coil. When the magnet 20 moves upward, the inductance of the coil 22 is increased. An arbitrary water level H0 is set by an adjusting screw 25. The water-level change exceeding the set water level can be continuously detected as the change in inductance of the coil 22.
