Title: Density detecting device
Inventor: YOSHINO KUNIHISA
IPC: G03G15/08
Filed: 1994-05-23
Abstract: PURPOSE:To always detect accurate image density in spite of compact constitution by providing diffusing plates at positions where a light emitting element and a light receiving element are opposed to respective substances to be detected and providing a light shielding plate at a part of the diffusing plate. CONSTITUTION:This device is provided with a base plate BP and an eaves CKC. The eaves CKC prevents contamination by toner or paper powder dropping from a cleaner positioned upward at the time of attaching an image forming device. The thin light shielding plate SP is provided between two diffusing plates DP1 and DP2. In this case, the light shielding plate SP is set between two diffusing plates DP1 and DP2 but it is good to integrate the light shielding plate SP with the diffusing plates DP1 and DP2. Unnecessary light is intercepted by the light shielding plate SP and is not made incident on the light receiving element PT, so that noise is remarkably reduced. Namely, the light from the light emitting element LED is reflected and diffused in the diffusing plates DP1 and DP2, and stopped from leaking to the light receiving element PT side, and the detecting accuracy of the image density is made high in spite of the compact constitution.

Title: Magnetic recording medium
Inventor: KIMURA AKIHIRO
IPC: G11B5/667
Filed: 1984-05-30
Abstract: PURPOSE:To prevent the exfoliation of the thin film of a magnetic recording medium such as, for example, a magnetic disk of a thin metallic film type and to improve the corrosion resistance thereof by providing a carbon nitride film as a protective film on the surface of the thin magnetic metallic film on the non- magnetic base of said medium. CONSTITUTION:The carbon nitride film 3 which is provided on the thin magnetic metallic film 2 and having about 0.02-0.15mum, for example, about 0.05mum thickness is formed by using, for example, an RF magnetron sputtering device which impresses RF power to a carbon target in gaseous nitrogen kept under about 10mTorr and heats the same to about 100 deg.C. The carbon nitride film 3 has C:N=1:3 atomic ratio according to an Auger analysis means. A contact start and stop CSS test is carried out in a disk driving system. As a result, the decrease in the reproduced output is hardly admitted even after 10,000 times of CSS with the magnetic disk on which the carbon nitride film is formed, while the reproduced outputs of the magnetic disk having no carbon nitride film formed thereon deteriorates by as much as 5dB after 1,000 times of CSS.

IPC: G01N1/10
Filed: 1993-04-12
Abstract: PURPOSE:To reduce gas consumption and improve responsibility by controlling a pump for sampling electric conductive coolant in fuel assemblies based on the detected amount by a flow meter. CONSTITUTION:A sampling port 22 is contacted on the upper part of a fuel assembly 21 to be measured. The flow of electric conductive coolant 31 rising up in a sampling tube 23 owing to water head and dynamic pressure is detected with a flow meter 25 and an electromagnetic pump 24 is controlled with a control circuit so that the signal amplitude becomes smallest. By this, the coolant 31 flow in the assembly 21 is stopped and temperature rise and pressure rise in the assembly 21 are caused. Then, by switching the polarity of a power source 33 for the pump 24, the coolant 31 is pumped up in a sampling tank 26. Gas is supplied through a supply pipe 27 to the pumped-up coolant 31 and returned back through an exhaust pipe 28 to a gas circulation system 29. Thus, the fission product in the coolant 31 moves in gas phase and, by measuring the radiation in the circulation system 29 with a radiation detector 30, existence of failure is identified.
