Title: Slidable material
Inventor: YOSHIDA TSUNEMORI
IPC: F04D29/046
Filed: 1992-05-14
Abstract: PURPOSE:To eliminate an oil leakage when being put under a high pressure, and maintain a sliding ability and a lubricating ability over a long period of time by absorbing lubricating oil in oil absorptive resin impregnated in a porous silicon carbide sintered body. CONSTITUTION:Lubricating oil 4 is absorbed in oil absorptive resin 3 impregnated in a porous silicon carbide sintered body 2 constituting a slidable member 1. Thereby, when being used in a nonpumping condition, the slidable surface of the slidable member 1 is lubricated always by means of an oil film of the lubricating oil 4 gradually released from the oil absorptive resin 3, and since an oil holding power of the oil absorptive resin 3 is strong, when being put under a high pressure, the lubricating oil 4 impregnated in the oil absorptive resin 3 can be prevented from leaking more than necessary, so that a sliding ability and a lubricating ability can be maintained over a long period of time. A stable sliding characteristic can also be obtained under such an ordinary service condition as pumping oil or water and under such a severe service condition as slurry is contained while pumping.

Title: Film thickness monitoring method for dielectric substance thin film
Inventor: NAKASHIMA HIROKI
IPC: G01B11/06
Filed: 1978-12-01
Abstract: PURPOSE: To enable highly accurate monitor, by calculating the film thickness at any time point  based on the specific equation, through the measurement of the deviation of resonance frequency  corresponding to the measurement interference photo pole point at the specified order, while forming the dielectric thin film on the substrate having piezoelectric characteristics.   
     CONSTITUTION: The dielectric substance piece 30 is evaporated to the substrate 20a having piezoelectric characteristics with sputtering and the resonant frequency deviation changing with the  thickness of the film 10a of the substrate 20a is measured with the frequency instrument 70 while  forming the dielectric substance thin film 10a. The output of the photo detector 60 takes extremal  value with the emission of the laser light in wave length λ and the interference light by the reflection light from the film 10a every time when the thickness of the film 10a reaches a multiple of  λ/(4n), where n is the refractive ratio of thin film. When the resonant frequency deviation Δf 0  of  the m-th order of extremal value is measured, the film thickness at any time point P can be  calculated by equation 1 depending on the measured resonant frequency deviation Δf. Accordingly, even if the proportional constant of the film thickness and the resonant frequency change is  unclear, and even if the film thickness is not a multiple of λ/(4n), the film thickness can be monitored with high accuracy.

IPC: B41M5/50
Filed: 1990-06-07
Abstract: PURPOSE:To decrease the extent of the contamination of an organic solvent with toner by making magnets attract toner which is separated from the recording medium and mixed with the organic solvent. CONSTITUTION:A transparent plastic sheet 10 is dipped in the organic solvent 28 and at the moment a sealing plate 44 abuts on a lid part 24, an ultrasonic vibrator 30 is excited to radiate an ultrasonic wave into the organic solvent from its vibration surface. Liquid molecules of the organic solvent 28 are vibrated with the ultrasonic wave and toner on the sheet 10 dipped in the organic solvent 28 separates speedily from the surface; and the suspended toner is mixed with the organic solvent 28 in a particulate state and attracted by the magnets 32 respectively. Therefore, even if the toner on the sheet 10 is suspended in the organic solvent 28, the amount of remaining toner in the organic solvent 28 is extremely small and the extent of the contamination of the organic solvent 28 with toner is reducible.
