Title: Method and apparatus for estimation of measured value by absorbance measurement
Inventor: KURIHASHI KATSUTOSHI
IPC: G01N21/31
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for the estimation of a measured value by an absorbance measurement, in which the measured value of a sample incapable of being measured by a spectroscopic analysis in conventional cases can be estimated. SOLUTION: A sample to be measured having a known measured value is irradiated with electromagnetic waves in the region of an ultraviolet part, a visible part or a near-infrared part. Absorption signal values at two or more wavelengths which are not constituted of only electromagnetic waves in a near- infrared part are detected. The absorption signal values at the two or more wavelengths are changed into an explanatory variable. The measured value of the sample to be measured is changed into an objective variable. A double regression analysis is performed. A working curve is found. On the basis of the working curve, a measured value is estimated from the absorption signal values at the two or more wavelengths of a sample to be measured having an unknown measured value.

Title: Design of salicide nmos transistor having shallow junction and reduced electrostatic discharge sensitivity
Inventor: AMERASEKERA E AJITH
IPC: H01L29/08
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To optimize transistor characteristics by employing established values of M parameter, β parameter and Rsub parameter thereby improving electrostatic/electric overstress performance. SOLUTION: An essential factor having effect on the behavior of an NMOS transistor is the β of a lateral NPN transistor and the amount thereof functions as an index of soundness of high current with respect to a lateral NPN transistor having a given Rsub . Critical level of β is 5 and a second breakdown trigger current I12 decreases abruptly as the β decreases below 5. The I12 also decreases as the Rsub decreases. A mechanism for determining the I12 is Joule's heat at the junction of a reverse biased drain substrate. When the β or Rsub is decreased due to increase of M, Joule's heat is increased and the I12 is decreased. Consequently, electrostatic discharge performance is lowered through shallow junction and thick salicide.

Title: Sewage treating device
Inventor: MORO MASASHI
IPC: C02F1/44
Filed: 1990-11-26
Abstract: PURPOSE:To control the growth of a cake layer, so that the cake layer does not exceed its predetermined thickness, by a method wherein the flow of the liq. to be treated is caused to act, as shearing force, upon the cake layer formed on the surface of filter material to scrape off the cake layer. CONSTITUTION:In a zone A, the liq. 2 to be treated is separated into filter cake and liq. by undergoing the suction force caused by driving a filter liq. suction pump 14 and through the filter material 9 of each filter element 5. The liq. is sent from the filter material 9 through a filter liq. passage 7 of a filter plate 8, a filter liq. suction tube 11, a filter liq. suction header pipe 12 and a filter liq. suction pipe 13 and then discharged therefrom. The filter cake is adhered to the membrane surface of the filter material 9 in a cake layer. In the zone A, since the liq. 2 flows through a passage defined between the filter materials 9 parallel to the surface of the filter material, the flow of the liq. 2 acts, as shearing force, upon the cake layer formed on the surface of the filter material to scrape off the cake layer, whereby the growth of the cake layer is so controlled as not to exceed its predetermined thickness.

IPC: E02F9/12
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To lock an upper structure to a lower structure by causing the free fall of a rod by means of its own weight. SOLUTION: A hydraulic cylinder 15 is mounted in an upper structure, with its rod 15C pointed downward. When the rod 15C of the hydraulic cylinder 15 is lowered in a free-fall mode, a main selector valve 24 shifts to a rod lowering position (c), selector valves 30, 31 for free fall shift to a communicating position (e), and a selector valve 32 for starting the free fall shifts to a communicating position (g). Thereby the rod 15C falls because of its own weight. When the rod 15C of the hydraulic cylinder 15 is lowered in a hydraulic fall mode, the main selector valve 24 shifts to the rod lowering position (c) and the selector valves 30, 31 for the free fall shift to a shutoff position (d). The rod 15C is thus lowered by pressure oil from a hydraulic pump 21.
