Title: Printed wiring board
Inventor: WATANABE SATORU
IPC: H05K1/11
Filed: 1988-05-31
Abstract: PURPOSE:To facilitate the circuit inspection of a densely wired printed wiring board using a cheap board inspection device by a method wherein board inspecting terminals are formed near the outside of an outer shape of the printed wiring board providing a necessary and sufficient insulating space between them and the terminals and a wiring inside the printed wiring board are connected with each other. CONSTITUTION:A pattern 6 connected with an external connecting terminal 4 is made to extend outside from an outer shape of a printed wiring board 1, and a board inspecting terminal 2 is formed on the end of the pattern 6. Here, the patterns 6 are composed of short and long patterns which are alternately arranged so as to make the board inspecting terminals 2 aligned. Therefore, a necessary and sufficient insulating space between the board inspecting terminals 2 can be assured without decreasing the densely wired printed wiring board 1 itself in a wiring density. By these processes, a circuit inspection can be realized independently of components packaged or not using a cheap inspection device.

IPC: G01F1/66
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To quicken measurement while saving power by providing a main flow rate measuring means interposed between an inlet and an outlet, and a branch flow rate measuring means provided in a channel branched in the downstream of the outlet and altering the measuring method of the branch flow rate measuring means through a communication means when the flow rate measured by the main flow rate measuring means drops below a predetermined value. SOLUTION: When a comparison means 13r detects a fact that a measurement control means 13p measured a flow rate (not an integrated flow rate but an instantaneous flow rate) preset in the setting means 13q of a main flow rate measuring means 13 a signal is delivered to a measurement control means 15p through a communication means 16x and a communication means 16a set individually in branch flow rate measuring means 15a. When the flow rate decreases below a specified level, the measurement control means 15p alters the measurement time interval depending on the flow rate. For example, measurement is performed frequently when the flow rate is still high in order to sustain the flow rate accuracy and the number of times of measurement is decreased as the flow rate decreases.  In the downstream of a branch channel 14, operation frequency of the branch flow rate measuring means 15a is altered when the flow rate of a main pipe decreases below a predetermined level.

Title: Combustion control method of surface melting furnace and controller therefor
Inventor: NAGAHAMA KAZUO
IPC: F23G5/50
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a combustion control method of a surface melting furnace and a controller which enable increase in the volume of processing by enabling combustion and melting over the entire surface of sludge. SOLUTION: A temperature difference obtained by subtracting the temperature of a main combustion chamber 24 from the temperature of a secondary combustion chamber 27 is determined at each specified time to examine whether the temperature difference tends to rise or the like. The results are used to judge the floating and dropping of sludge and the presence of combustion within the secondary combustion chamber. When the combustion exists, the amount of main combustion air supplied is lowered and a combustion and a melting are performed with priority on the prevention of the floating and dropping of unburned sludge. When no combustion exists, the amount of the main combustion air supplied is increased thereby promoting the combustion and melting.

IPC: B22F9/14
Filed: 1985-06-24
Abstract: PURPOSE:To efficiently produce ultrafine particles by generating an arc between a crucible consisting of a high melting conductive material and a electrode and forming a raw material into the ultrafine particles by the heating of the crucible. CONSTITUTION:The inside of a chamber 2 is first evacuated to a vacuum and thereafter an inert gas is introduced therein to maintain an inert atmosphere therein. The arc 9 is then generated by a tungsten electrode 3 as a cathode and the raw material 4 in the tungsten crucible 5 as an anode. The crucible 5 is heated to a high temp. by the generation of the arc 9 and the raw material 4 is heated by the heat thereof. The arc 9 is automatically generated from the material 4 when the raw material has electrical conductivity. About <=1mu ultrafine particles are thus efficiently produced even from the low melting material and highly conductive material.

IPC: C02F1/62
Filed: 1978-11-04
Abstract: PURPOSE: To economically recover silver as silver nitrate from a waste fixing soln. by adding nitric acid to the soln. to acidify it; filtration-separating precipitates formed; adding dichromate to the filtrate after adjusting to pH 2; and treating the resulting Ag 2 Cr 2 O 7  with hot nitric acid, a special ion exchange resin, etc.  
     CONSTITUTION: A waste fixing soln. in acidified with nitric acid to decompose thiosulfate ions, and precipitates formed are filtration-separated. The filtrate is adjusted to pH2, and dichromate is added to form silver dichromate precipitates, which are then dissolved in hot water or hot nitric acid (1:5). This soln. is treated with a NO 3  type anion exchange resin to allow dichromate ions to be adsorbed on the resin. Since the effluent contains only silver as cation, high purity silver nitrate crystals can be recovered economically by concentrating and evaporating the effluent to dryness.

Title: Semiconductor device
Inventor: NAKAIMUKI MASAYUKI
IPC: H05K9/00
Filed: 1988-06-02
Abstract: PURPOSE:To make it maintain electrostatic shielding effect so as to prevent malfunction by an electric field by providing a conductive layer fixed at constant potential and a protective film at the surface of a circuit element constituted on a semiconductor substrate. CONSTITUTION:In case that there is a semiconductor device in an electric field, even if the electric field is applied in the direction vertical to a chip 1 surface, by a conductive layer 8 fixed at the constant potential for electrostatic shielding, an external electric field does not reach a circuit element below the conductive layer 8, and even if undesirable charge arises it is limited above the conductor layer 8, so abnormal charge does not arise inside the circuit element. Also, since the conductive layer 8 and the p-type silicon substrate are equal in potential in view of CMOS structure, the circuit element caught by these two is not affected by the effect of the electric field and can perform normal function operation.
