Title: Surface treatment of metallic powder containing silicon for coated electrode
Inventor: YAMANOUCHI NAOMI
IPC: B23K35/40
Filed: 1980-10-15
Abstract: PURPOSE: To stick potassium permanganate on the surfaces of metallic powder and prevent the dry cracking of a welding rod coating material by heating the mixture of metallic powder contg. silicon and an aq. potassium permanganate soln. to limited temps.  
     CONSTITUTION: 2W25% aq. permanganate soln. is added to metallic powder contg. silicon at 20W50% based on the weight of the metallic powder contg. silicon. Next, the mixture of the metallic powder and the aq. potassium permanganate is heated to 60W90°C to stick the potassium permanganate on the surface of the metallic powder. With heating at below 60°C at this time, it takes too much time for the treatment of the metallic powder, and with heating above 90°C, it is not possible to suppress the dry cracking of the coating material of the welding rod. If the potassium permanganate powder is added and stuck further until the residual moisture of the metallic powder subjected to the above-described surface treatment lowers down to 1.0wt%, the amt. of the potassium permanganate to be stuck on the metallic powder is decreased.

These terminals serve as the connecting terminals to the external lead terminals. The two floating electrodes 5 and 5' are provided on the rear side of the plate 1 and at the positions opposite to the electrodes 2 and 3 as well as electrodes 3 and 4, respectively. Thus an edge mode ceramic filter is obtained. A groove is formed at the center part of the electrode 3 to control the resonance frequency due to the variances of the piezoelectric material and the mechanical working. Thus the resonance frequency of an edge mode vibration can be easily controlled in accordance with the depth and the substantial inner diameter of the groove.

Title: Methods for shape straightening of substrate surface and for polishing thereof
Inventor: SUHARA TAKASHI
IPC: B23Q3/08
Filed: 1992-05-12
Abstract: PURPOSE:To reduce the thickness difference between both sides of a substrate by deforming one side of a substrate while attracting it and by straightening the opposite side of the attracted side into a desired shape. CONSTITUTION:An attracting side 6a of a substrate is sucked by a straightening chuck 7. In this condition, a shape of the opposite side of the attracting side 6a, that is, an adhesive side 6b is measured by using a surface shape measuring device, e.g. optical interference system, and the error from the target surface shape is calculated by entering the measured data of the shape of the adhesive side 6b in a control computer. On the basis of the calculation result, the shape of the attracting side 6a is altered by using straightening chuck 7 so that the adhesive side 6b of the substrate 6 is made flat, and the error is corrected. In addition, the surface shape of the substrate 6 is measured. When an error is found, correction is made again, and the process is repeated until an error goes in an error allowance range. As a result, the thickness difference between both sides of the substrate 6 after polishing can be reduced.

Title: Tv conference system, control method for the same and program storage medium for controlling tv conference system
Inventor: HIRATA HIROMASA
IPC: H04N7/15
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a TV conference system where wasteful transfer can be omitted and the processing burden of a client and a load on a network can be reduced by transmitting voice data and picture data, which are transmitted from a transmission source client, to a transmission destination client when inputted voice data is judged to be the voice of a user. SOLUTION: When a transmission source client is a client A1102, the client A1102 judges whether inputted sound data is the voice of a user or environment noise. When inputted sound data is judged to be the voice of the user, inputted voice data is transmitted to a server 1101. Thus, the client A1102 transmits voice data to the server 1101 only when the user emits it. The server 1101 transmits received voice data to a client B1103 when data is to be transmitted to the transmission destination client B1103. Thus, a network load can be reduced.
