Title: Manufacture of plate group for lead storage battery
Inventor: KITOU KAORU
IPC: H01M50/541
Filed: 1983-08-26
Abstract: PURPOSE:To eliminate bubbles so as to perform complete fusion in making a plate group by applying ultrasonic vibration to a strap formation mold at the same time when a molten lead alloy is poured into the concave area of said formation mold after plate lugs are inserted into the concave area. CONSTITUTION:When forming a plate group 7 by connecting the lugs 2 of positive plates 1 by means of a strap 6, ultrasonic vibration is applied from an ultrasonic wave generator 8 to a strap formation mold 3 at the same time when a molten lead alloy 5 is poured into the concave area 4 of the formation mold 3 after the lugs 2 are inserted in the concave area 4. By the means mentioned above, it is possible to prevent any contamination of the fusional section by bubbles by eliminating the bubbles of the molten lead alloy 5 and by inhibiting formation of bubbles between the lugs 2 and the molten lead alloy 5, thereby achieving a state of complete fusion. As a result, it is possible to prevent any separation and deformation of the lugs 2 which might be cuased by vibration or shock during manufacturing as well as any fusing and the like of the lugs 2 during large current discharge.

IPC: G06T1/00
Filed: 1985-07-18
Abstract: PURPOSE:To make a rotation processing possible by using a small real memory and small number of multipliers by making input information into blocks and making the rotation processing in unit of block. CONSTITUTION:The image information of a disk 4 is read out in unit of block and set to input buffers 6, 7. Reading of the block is made in the direction of main scanning and in the direction of auxiliary scanning while overlapping by a specified amount. Picture element data of picture image data of buffers 6, 7 are rotation processed by an image rotation calculating section 9 according to parameter inputted from a parameter inputting section 1, and stored in output buffers 11, 12. Center coordinate of the block is calculated by a parallel displacement calculating section 15 according to the parameter, and the image data of output buffers 11, 12 are written in blocks of the disk 16 that makes the calculated value center coordinate. Thus, it is enough for the parallel displacement calculating section 15 to calculate only once for each block, and a high speed multiplier becomes unnecessary. As the conversion is made at every block, it is not necessary to have the real memory for whole area of the image.

Abstract: PROBLEM TO BE SOLVED: To realize a capacitor which is lessened in size and enhanced in capacity. SOLUTION: A metallized film 2 is formed on a board 1, and then a high-molecular precursor electro-deposit film 3 is formed thereon through an electro-deposition process and thermally treated into a high-molecular thin film 4. Thereafter, the metallized film 2 is dissolved with an acid or alkaline solution to separate and remove the board 1. Metal is evaporated on each side of the high-molecular thin film 4 to form a metal electrode 5. An electro-deposition process is carried out through such a manner that the metallized film 2 formed on the board 1 is made to serve as an anode and dipped into a polymer-containing electro-deposition solution confronting a cathode, and a voltage is applied between the anode and cathode to form the electro-deposition film 3 on the metallized film 2.  In the above electro-deposition process, high-molecular precursor contained in a polymer-containing electro-deposition solution is made to migrate electrically, so that the high-molecular thin film high in density and uniform in thickness is obtained, and a capacitor of various type such as laminated-type, rolled- type, or the like can be lessened in size and enhanced in capacity by the use of a film where the metal electrode 5 is formed on each side of the high-molecular thin film 4.

Abstract: PURPOSE:To prevent damage to elements by a method wherein the resistance value of high- resistance elements for contact resistance confirmation is measured and after the rising and falling stroke of a probe card is decided, the contact state of a contact probe and the elements is detected. CONSTITUTION:An electrode 14 of a higher-resistance element 12 for contact resistance confirmation and a contact probe 3 are brought nearer to each other until the specific resistance value of this element 12 is measured and the rising and falling stroke of a probe card 2 is decided in such a way as to regard a position where the specific resistance value of the element 12 is measured as the contact position of the contact probe 3 and the element. Then, the contact probe 3 is brought into contact to an electrode 15 of an element 13 for contact resistance confirmation on the other side to measure the resistance value of this element 13 and if the resistance value is smaller than the previously set value, the contact state is good, but if it is larger than the setpoint, a cleaning of the needle tip is performed. After this adjustment is repeated until the measured values become smaller than the setpoint, the probe card 2 is descended on general elements 11 at the previously decided rising and falling stroke and the characteristics are measured. Thereby, the contact state of the contact probe and the elements can be always detected while a proper contact pressure is applied.

As a result, the specific resistance of the layer 16 is recovered to that of the layer 15 and the strangulation of the inner current becomes possible. Lastly, the pattern of SiO2 17 and the electrode 19 are formed. According to this constitution, the heat deformation near the luminous portion is decreased and the life characteristic is improved since there exists no conventional depression construction.

Title: Welding method of thin sheet
Inventor: UKAI JIYUN
IPC: B23K9/00
Filed: 1979-12-06
Abstract: PURPOSE: To make it possible to perform excellent welding on thin sheets which have large gaps in their welding parts, by alternately repeating the first stage welding which is to be performed under specified welding conditions and the second stage welding to be performed with a normal arc in consumable electrode type gas sealed arc weldings.  
     CONSTITUTION: In the consumable electrode type gas sealed arc welding method, the first stage welding is performed by connecting resistance 8 to power source 7 and with a low current compared with normal arc weldings. The first stage welding is performed in such a way that, when welding wire 2 supplied to base metal 9 short-circuits with base metal 9, wire 2 becomes red due to the short-circuit current and it is melted. After this first stage welding procedure is repeated twice, the second stage welding which is to be performed with a stable normal arc is carried out. These first and second stage weldings are alternatively repeated successively. By this welding method, an excellent welding metal having no melt down can be produced, even if there is a large gap in the welding part of thin plate (≤1mm).
