Patent JP-H03189399-A (JP)
Title: Fan device
Inventor: SATO HAJIME
IPC: F04D29/34
Filed: 1989-12-18
Abstract: PURPOSE:To reduce the generation of noise by loosely engaging a fan mounting part with a shaft, forming a through-hole, extending at right angles with a shaft, in the fan mounting part, mounting a pin, loosely engaged with the through-hole, on a shaft, and providing a resilient body to energize the fan mounting part toward the end part of a shaft. CONSTITUTION:A resilient body 10 is inserted externally of a shaft 1 together with a retaining ring 9, a boss 2 (fan mounting part) is then mounted on a shaft 1, and a through-hole 4 of the boss 2 is adjusted to the same position as that of an insertion hole 5 of the shaft 1 to press a pin 6 in the insertion hole. When the shaft 1 is rotated, the boss 2 is rotated to rotate blades 3. The boss 2 is always pressed toward the end part side of the shaft 1 through the force of the resilient body 10 and since the pin 6 and the through-hole 4 are deviated from each other, when the shaft 1 is started to rotate, friction between the pin 6 and the through-hole 4 is provided. Vibration is not generated by a loose engaging state produced at the part between the pin and the through-hole, and the blades 3 are smoothly started. Besides, slight vibration in a rotational direction transmitted from the shaft 1 to the boss 2 is adsorbed since the pin 6 and the through-hole 4 are not firmly fixed to each other but moved only by an amount enough for absorption of vibration.

Filed: 1987-12-22
Abstract: PURPOSE:To perform the Fourier transform, which takes much time, in real time and to obtain a standardized average power spectrum image of high resolution by providing a specific means which processes the output from a television camera whose light receiving face is arranged in the image forming surface of a telescope. CONSTITUTION:Images picked up by the television camera which has the light receiving face arranged in the image forming surface of the telescope are successively taken into a frame memory and are converted to still images, and these still images are not only stored in a spatial optical modulating tube but also read out by the laser beam and incoherent images are converted to coherent images. Coherent images are optically subjected to Fourier transform to obtain power spectrums, and they are added and accumulated on the frame memory with respect to respective still images and are divided by the preliminarily taken-in power spectrum of a reference start. Thus, much Fourier transform is performed in real time, and double starts are observed in a short time by division based on the reference start, and the standardized average power spectrum image of high resolution is obtained.

Title: Simultaneous analysis of benzoic acid, sorbic acid and dehydroacetic acid
Inventor: MURAKITA HIROYUKI
IPC: G01N30/26
Filed: 1989-12-15
Abstract: PURPOSE:To separate three components; benzoic acid, sorbic acid and dehydroacetic acid without generating the tailing of peaks by using a mobile phase contg. a specific concn. of magnesium ions and analyzing a sample contg. the benzoic acid, sorbic acid and dehydroacetic acid with a column for reversed phase chromatograph. CONSTITUTION:The sample contg. the benzoic acid, sorbic acid and dehydroacetic acid is analyzed with the column 4 for reversed phase chromatograph by using the mobile phase contg. at least 0.05M magnesium ions, by which the benzoic acid, sorbic acid and dehydroacetic acid are simultaneously analyzed. The reason for confining the concn. of the magnesium ions to at least 0.05M lies in that if the concn. is below 0.05M the effect of the magnesium addition does not appear and the tailing of the peaks still arises. About <=0.3M is preferable as the upper limit of the magnesium ions in terms of dissolution to the mobile phase. The form of the magnesium to be added to the mobile phase is exemplified by, for example, magnesium acetate, etc., and the solvent to dissolve the magnesium salt is exemplified by, for example, a phosphoric acid buffer soln.
