Title: Manufacture of semiconductor device
Inventor: TATEFURU NOBORU
IPC: H01L21/336
Filed: 1989-12-01
Abstract: PURPOSE:To restrain a crystal defect of a semiconductor element from being produced by a method wherein a high-concentration diffusion layer of impurities forming a second conductivity type or a semiconductor layer containing impurities is formed, as a getter layer, on a second main face on the opposite side of a semiconductor substrate. CONSTITUTION:A thermal oxide film 2 is formed on an n-type Si wafer 1 in an atmosphere. In a state that the surface of the wafer is covered with a photoresist, the wafer is treated with an HF-based etchant; the oxide film on the rear side of the wafer is removed. In succession, boron is deposited and diffused; a boron silicide layer 7 and a high-concentration diffusion layer 8 are formed on the rear of the wafer. After B has been diffused to the rear of the wafer, a window is opened in one part of the oxide film 2 on the surface by using a photoresist mask 3; ions of boron are implanted through an opening part 4; a p-type impurity deposition layer 5 is formed. Then, the photoresist mask 3 is removed by a plasma ashing method and an ozone sulfuric acid method. The layer is etched and cleaned; a well region 6 is formed by a diffusion treatment in an oxidizing atmosphere.

IPC: G01N31/00
Filed: 1993-11-04
Abstract: PURPOSE:To determine the quality of drink water, water for hood industry, and well-known water for brewing Japanese sake conveniently and quickly using a biosensor taking advantage of fixed yeast. CONSTITUTION:Brewing yeast fixed to agar is caused to react on mineral components in a water to be inspected thus causing fermentation of alcohol. Mineral components are then detected quickly and other organic components and irons are detected by pack test. The quality of well-known water is determined quickly and conveniently by considering the components thus detected collectively. The quality of well-known water for drinking, food industry, or brewing is determined based on a different criterion.

Title: System and method for controlling laser frequency and system and method for processing signal
Inventor: EPWORTH RICHARD EDWARD
IPC: G02F1/01
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate errors which occur in a dither amplitude due to an unnecessary AM component outputted as a result of dither modulation. SOLUTION: A laser frequency control system which controls the frequency of a laser 1 in an optical transmission system is composed of a means 34 which performs frequency modulation on the laser 1, a means 35 which is provided on the downstream side of the laser 1 and decides amplitude modulation in a signal caused by the frequency modulation, a means 36 which discriminates an amplitude-modulated section the phase of which intersect that of the modulated frequency at nearly right angles, and a means 37 which controls the frequency of the laser 1 based on the discriminated orthogonal section.  An optical element positioned on the downstream side of the laser 1 has a response which converts FM components into AM components, and the response and frequency output from the laser 1 can be locked to each other without causing any error due to the unnecessary AM component in the modulated frequency of transmitted signals.

Abstract: PURPOSE:To obtain a function of multiplicity by a simplified structure, by selecting three kinds of transmission routes, which starts from the first and second output elements of a center differential gear reaching either one or the other of front and rear wheels directly or through a viscous coupling, by a single selector mechanism. CONSTITUTION:A sleeve 74 of a selector mechanism 70 in a transfer device 3 is moved, for instance, to the left side, and if the first and second splines 71, 72 are connected, a center differential gear 40 is locked by connecting a carrier 44 with a sun gear 41. Consequently, input torque from a transmission output gear 9 to the carrier 44 is output being left as it is from a ring gear 45 and transmitted to a rear wheel with no division by the center differential gear 40. While a front wheel is not driven because the second and third splines 72, 73 are separated. Here if a rotary speed difference is generated between the front and rear wheels, output torque from the ring gear 45 is respectively transmitted to the front and rear wheels because a viscous coupling 50 transmits torque.
