IPC: H03M7/40
Filed: 1985-04-13
Abstract: PURPOSE:To attain efficient transmission by dividing a dynamic range into N groups and expressing the data with a fixed word length part representing a group and a variable word length word representing up to an unit quantization level in the group. CONSTITUTION:All the dynamic range is divided into N (n0-n1, n1-n2,..., nN-1-nN) level regions by M quantization levels so as to make the appearence probability of a signal corresponding to each level region equal. Then each level region is divided into a unit quantization level and when N is, e.g., 8, the fixed word length representing the group is takes as 3 bits. In order to express a detailed level in the group, the variable word length is used. In taking a dynamic range as 0-254, the variable word length part has 0-7 bits. When the appearence probability at each range region is equal, the 1-word mean bit length is nearly 6.5-bit.

Title: Output circuit
Inventor: SAKAIDA MASAHIKO
IPC: H03K19/003
Filed: 1990-03-26
Abstract: PURPOSE:To suppress the fluctuation of a potential and to prevent malfunction by flowing a current through a transistor(TR) with small driving capability at the initial time of changing a signal. CONSTITUTION:Corresponding to a start input from an input terminal 10, P type TR 1 and 2 are turned on and N type TR 3 and 4 are turned off. Since a W/L for the width/length of a gate in the TR 2 is small, the output signal from an output terminal 11 is made smooth. Next, when an output point 21 reaches a high level, an N type Tr 6 is turned on and a low level signal is supplied through a delay element 9 to a gate. Then, a P type TE 7 is turned on. In such a case, since the W/L of the TR 4 and 7 and an N type TR 8 is large, the driving ability is made large and an output charge speed is made high as well. Even when an end input is applied, the state is made similar and an output circuit is obtained to prevent the malfunction from being generated by suppressing the output potential fluctuation caused by the speedy start and end.

Title: Treatment before welding for sintered material
Inventor: YANAGAWA KOKI
IPC: B23K11/14
Filed: 1993-04-05
Abstract: PURPOSE:To improve the welding of a sintered material. CONSTITUTION:Before welding, a sintered material 1 contg. oil, water, strains or the like through dimensional straightening and machining is heated to 400 to 600 deg.C in an inert atmosphere of nitrogen or the like. In this way, the oil, water, strains or the like are perfectly removed away. By the removal of the oil, water, strains or the like, there is no generation of blow holes 4 on the weld zone 3 as shown in the drawing, and the welding can satisfactorily be executed. Because of the heating in an inert atmosphere, oxygen contained in the sintered material 1 is reduced, and the sintered material 1 is hard to oxidize at the time of the welding. Because the heating temp. is 400 to 600 deg.C, the dimensional change in the sintered material 1 does not occur.

Abstract: PROBLEM TO BE SOLVED: To prevent the damage of an electrode connecting part and the coming off of an electrode by performing the shrinkage fitting of annular fastening members to a socket peripheral part located inside more than the edge of an electrode pole and fixing the fastening members to the electrode pole by using anchoring means. SOLUTION: Slot parts 4 are formed around the peripheral part of a socket 2 located inside more than an edge 1A of an electrode pole 1 and annular fastening members (band members) 5 having a width almost equal to that of the slot parts 4 are shrinkage fitted to the slot parts 11. In this case, by performing the shrinkage fitting of the fastening members 5 in the peripheral part of the socket located inside more than the edge 1A of the electrode pole 1, the pressing force to the socket 2 against the side wall due to the fastening of the band members 5 is reduced and its tapered form is not changed. so that the damage prevention effect on a connecting part is sufficiently maintained.  In addition, even if the fastening members 5 are heated and thermally expanded, the fastening members 5 are prevented from being slidingly dropped by being blocked by the slot parts because of being fitted to the slot parts 4. The sliding drop of the fastening members 5 can be further surely prevented by fixing the fastening members 5 to the slot parts 4 by the aid of anchoring means 6.
