Patent JP-H03233905-A (JP)
Title: Manufacture of square chip-shaped resistance
Inventor: ASAKAWA YOSHITAKA
IPC: H01C17/06
Filed: 1990-02-08
Abstract: PURPOSE:To enhance the formation operation efficiency of an electrode, a resistor and the like and to decide the shape and the size of a product satisfactorily by a method wherein the electrode and the resistor are formed on a green sheet, the green sheet is divided into base bodies (single products) and, after that, the base bodies are baked and solidified. CONSTITUTION:Electrodes 3 of silver palladium or the like are formed on a green sheet 10. Resistors 7 are printed and formed in a state that they come into contact with the electrodes 3. The electrodes 3 and the resistors 7 are formed and both are divided into single products before the green sheet 10 is baked and solidified. Consequently, due to the difference in a contraction rate by a baking operation of the green sheet 10, it is not required to form the electrodes 3, the resistances 7 and the like by classifying a substrate into ranks. As a result, the manufacturing operation efficiency is enhanced. Since a burr, a break and the like are not caused at a breaking operation, the shape and the size of a product can be decided satisfactorily.

Title: Manufacture of semiconductor integrated circuit
Inventor: INO MASAYOSHI
IPC: H01L29/08
Filed: 1978-03-16
Abstract: PURPOSE: To make a junction shallow and sheet resistance low by carrying out shallow deposition with low density through ion implantation using as diffusion impurities arsenic whose diffusion coefficient is one-figure slow than that of phosphorus.  
     CONSTITUTION: Arsenic slow in diffusion coefficient is ion-implanted by energy of approximate 100 to 150KeV to the dope amount of 1 × 10 16 /cm 2 , thereby forming a N +  layer. Next, non-dope SiO 2  11 is grown by CVD to a thickness of approximate 1000Å in order to attain masking for the prevention of the out-diffusion of arsenic due to annealing in the next process, and also to prevent phosphorus from diffusing directly to the silicon substrate from PSG to be deposited next.

Abstract: PURPOSE:To enhance the supply amount of oxygen for improving the efficiency of purifying waste water, by independently providing a means for circulating water to a filthy water disposal channel formed into a horizontal closed channel and an oxygen supply means for supplying oxygen to the interior of said channel. CONSTITUTION:Waste water having flowed through a sedimentation basin 6 into a ditch 1 is mixed with activated sludge in the ditch 1 and circulated through the ditch 1 by a water circulating means 10. In the water circulating means 10, the removal of nitrogen is performed. Thereafter, the liquid mixture is circulated through an oxygen supply means 11.

Hereon, the oxygen supply means 11 is exclusively used for the supply of oxygen, so that the sufficient amount of oxygen can be supplied. In addition, it is easy to control oxygen supply. At a part apart from the oxygen supply means 11, the amount of dissolved oxygen is reduced to form an anaerobic zone. Hence, denitrifying reaction is accelerated.

Title: Gain flattening apparatus for wavelength multiplexing optical transmission path
Inventor: WATANABE TOSHIAKI
IPC: H01S3/06
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To compensate the variation of an amplification factor according to the wavelength by disposing an optical component consisting of a material containing Tb element on the way of a wavelength multiplexing optical transmission path having an optical stimulation amplifier based on an Er element doped optical fiber. SOLUTION: Signal light 4A in 1550 nm and 1580 nm bands transmitted in an optical transmission system is amplified when it is transmitted through an optical stimulation wave-composing fiber 2, because the Er element in the fiber 2 is stimulated by stimulating light 4B emitted from an stimulating light source 1 which is a semiconductor laser so that induced emission takes place. The amplified transmitted light 4C in the 1580 nm band has a gain larger than that in the 1550 nm band and they are uneven, therefore when the light 4C passes through an optical isolator 3 having a Faraday rotater 11, the 1580 nm band is absorbed stronger than the 1550 nm band in accordance with the absorption characteristic of Tb element, so that the gain of emitted signal light 4D is flattened. Thus, the variation of an amplification factor according to the wavelength can be compensated.

Abstract: PURPOSE:To improve linearity and reduce an offset and to obtain the liquid crystal display device of high picture quality by charging or discharging signal lines of a liquid crystal panel to a constant potential before a video signal is impressed. CONSTITUTION:The signal lines 12 of the display panel 125 are charged or discharged to the specific constant potential before the video signal is impressed from a horizontal driving circuit 24 to drive the signal lines 12.
