Title: Joining method of metallic member
Inventor: TAKAHARA KATSUO
IPC: B21K25/00
Filed: 1984-04-11
Abstract: PURPOSE:To join members together in high adhesive-degree and in excellent strength and to mak a process short, by plastically flowing the members with each other under a restricting formation and joining the members together by deforming them. CONSTITUTION:When a restricting formation is started in a state of mounting a slug 4 on a lower die and a pin 5 on an upper punch 8 after boring a hole in the slug 4 for inserting the pin 5, the pin 5 is inserted to the position where a space 9 is left at its front end. Thereafter, when the punch 8 is lowered, a compressive force is added to the diametral direction of the inserted pin 5 by a pressing force P of punch 8, and when the force P exceeds the yielding point of pin 5, the pin 5 extends its front end into the space 9 while flowing plastically. And an intermediate part 10 is contracted to tightly contact with the plastically flowing part of slug 4, and is joined to each other, thereby forming the appearance.

Title: Manufacture of platinum alloy spring material for ornament
Inventor: HAMADA TOKIO
IPC: A44C27/00
Filed: 1989-03-24
Abstract: PURPOSE:To obtain the spring material which is hard and having excellent spring properties, at the time of manufacturing the spring material constituted of prescribed ratios of platinum, Ga and copper, by executing brazing of parts and thereafter subjecting the material to heat-treatment in a specified temp. area. CONSTITUTION:In the method for manufacturing the platinum alloy spring material for ornaments constituted of, by weight, 84 to 96% Pt, 1 to 10% Ga and 0.5 to 10% Cu, after the brazing of parts, heat-treatment is executed at 400 to 600 deg.C. The heat-treatment is executed for hardening the spring material by dispersedly precipitating Ga into crystals; in the case of <400 deg.C, it is not sufficiently hardened, and in the case of >600 deg.C, the spring material is softened or the brazing filler metal is melted. By this method, the spring material suitable for clip-type ornaments such as a spring of a necktie pin and a clip-shaped brooch can be obtd.

Patent JP-H01244503-A (JP)
Title: Sequence controller
Inventor: KOMINAMI SHINYA
IPC: G05B19/05
Filed: 1988-03-25
Abstract: PURPOSE:To eliminate a need for excess processings to sequence processing execution other than interruption handling at the time of switching from a sequence fundamental instruction to a sequence extended instruction by jumping the processing of a multibit processor to an extended instruction routine corresponding to the instruction code in an extended program memory. CONSTITUTION:When the sequence instruction in a program memory 3 is changed from a fundamental instruction to an extended instruction, a one-bit processor 1 interrupts a multibit processor 2 and the control right of the sequence processing is transferred to the multibit processor 2. The multibit processor 2 reads out the extended instruction as an interruption vector, and simultaneously, the processing of the multibit processor 2 is jumped to the extended instruction routine corresponding to the instruction code in an extended program memory 5. Thus, excess processings to sequence processing execution other than interruption handling are unnecessary at the time of switching from the sequence fundamental instruction to the sequence extended instruction.

Title: Connecting device for seat belt
Inventor: TAKAHASHI TOSHIMUNE
IPC: B60R22/26
Filed: 1994-04-12
Abstract: PURPOSE:To accomplish reversible movement and smooth movement of a connecting apparatus by preventing movement in the feeding direction in the connecting apparatus for a seat belt by means of a locking means and arranging a movement assisting member reducing a moving resistance between the locking means and a guiding means. CONSTITUTION:In an emergency, a wire 21 is strained in the retracting direction B of a seat belt at once. Therefore, a knuckle 7 is moved in the direction B, and a locking means L is moved in the direction B while a slider 9 is guided by a rail 15, so that a buckle 1 is pulled in the same direction, and consequently, the seat belt is retracted. In this process, a moving resistance is reduced by means of a movement assisting member 50, and the locking means L is smoothly moved. On the other hand, if tension due to an occupant acts on the seat belt, the buckle 1 is moved in the direction A. Therefore, the knuckle 7 is moved in the same direction so as to rotate around a center pin 11 and bites in a rail 15, and as a result, the slider 9 is lifted. Consequently, the movement assisting member 50 is broken, and a moving resistance reducing function is reduced.

Title: Setting method of spare transmission line for data transmission line network
Inventor: SEGAWA KUMIKO
IPC: H04M3/00
Filed: 1984-04-14
Abstract: PURPOSE:To set up a new spare circuit by setting first temporarily a spare circuit to connect two stations in the shortest distance when a using circuit has a disconnection, reading the using frequency out of a memory for the set spare transmission line and swtiching a spare transmission line having an extremely high using frequency to another spare circuit which is set between same stations and has a lower using frequency. CONSTITUTION:The network data Din is supplied to an input terminal 31, and the desired data on a data transmission line network are collected. For each of all in-use transmission lines, the route of a spare transmission line which can be formed with the shortest distance is set to maintain a function equivalent to a using circuit being disconnected. In such a case, the set route reaches directly a Dout from an output terminal 36 as long as the shortest distance is effective in consideration of the information on the using frequency fed from a using frequency memory 34 for spare transmission lines. When a spare transmission line having a high using frequency is detected through results of decision, a block 35 refers to the memory 34 again to allocate another spare transmission line having a low using frequency. Based on the contents of the Dout, the data stored in the memory 34 corresonding to he spare transmission line used just now is renewed by (+1).

Title: Composting device
Inventor: YAMAMOTO TOSHISHIGE
IPC: C05F7/00
Filed: 1980-06-02
Abstract: PURPOSE: To reduce the driving power of a blower for ventilation by controlling the direction of force ventilation, preventing dewing and humidifying in the material to be treated in the upper part of a fermentation tank, maintaining good air permeability.  
     CONSTITUTION: An air diffusing pipe 7 having multiple vent holes 7a is inserted into the central part of a fermentation tank 1, and is coupled to a pipe 3 so that the supplied air is released radially from the holes 7a. Hence, the air required for aerobic fermentation flows in the radial direction of the tank 1 from the pipe 7 toward the outside circumference, and therefore the air past the high-temp. part in the material 6 to be treated is prevented from contacting the cold material to be treated  right after charging and from causing dewing and humidifying. Since the length of  the flow passage of the air in the material is short and the required air flows in  parallel in the material 6, the air resistance for passing through the inside of the  material 6 is reduced.
