Title: Manufacture of tube by hot extrusion
Inventor: KEYAKIDA OSAMU
IPC: B21C23/08
Filed: 1992-01-21
Abstract: PURPOSE:To prevent the diameter of the bottom part of an extruding tube from expanding and to prevent a mandrel from being damaged by detecting a stem speed during extrusion, estimating a finish time of extrusion and com manding a retreat to its drive system so that the mandrel begins its retreat at the time of an estimated extruding. CONSTITUTION:The relation between the stem speed when the stem 1 passes a specified position and the time required from its pass till the finish of extrusion is formed in each extruding condition. While the stem is extruded, a stem speed is detected to estimate the finish time of extrusion. Then, the retreat of a mandrel 6 is commanded mode determination to a mandrel drive system in consideration of a delay time of motion in the mandrel drive system so that the mandrel 6 starts its retreat at the time of end of estimated extrusion.

Title: Method of forming solder bump
Inventor: GONDA MAKOTO
IPC: H01L21/60
Filed: 1993-01-27
Abstract: PURPOSE:To obtain a bump with a height (or thickness) by applying ultrasonic vibration to fused solder thereby granulating fused solder, and sticking the granular fused solder to the solder adhesive face of a work. CONSTITUTION:When ultrasonic vibration in cross direction is applied to film- shaped fused solder 9, the fused solder on a chip 8 is sprayed toward the solder adhesive face of a work 1, becoming the particles with diameters of 1 to several hundred microns. A pretreatment part 6 sucks and condense nearby solder particles 9a by the surface tension, and a solder lump, which has grown as a solder bump 13, and adheres to it. Moreover, solder lumps 9b, which have grown by many solder particles 9a attracting one another by surface tension, adhere lightly to the surface of a passivation film 4. Hereby, a large-sized and especially, a high solder bump can be formed by sticking a large quantity of solder.

Title: Position detecting method for assembly parts
Inventor: OHARA SHUICHI
IPC: G05B19/18
Filed: 1991-02-01
Abstract: PURPOSE:To detect the position of a part which is to be assembled to a part held by an end effector of a robot among two parts with a shaft and hole fitted closely to each other. CONSTITUTION:A position detecting jig 10 is held by a gripper 5 so that its center axis may be parallel with the center axis of a part 2 (hole 3) and its tapered portion may be faced downward. When the position detecting jig 10 is lowered along its center axis by a robot 4, the side surface of the tapered portion is made in contact with the edge of the hole 3 and the position detecting jig 10 receives a force in the direction perpendicular to the center axis. The force increases as the position detecting jig 10 lowers over a limited value, and then the actions by which the position detecting jig 10 is moved by an amount in the direction of a force perpendicular to the center axis and the position detecting jig 10 is lowered further from that position until it is pressed against the part 2 are made repeatedly. Then, when the shaft of the position detecting jig 10 is inserted into the hole 3, it does not receive any force and, therefore, alignment of the center shaft of the position detecting jig 10 with that of the hole 3 is detected to detect the position of the part 2.

Title: Film end detector
Inventor: INOUE AKIRA
IPC: G03B1/60
Filed: 1983-02-28
Abstract: PURPOSE:To prevent a camera which detects a film end by counting the time of film winding by a motor from malfunctioning owing to the state of a power source by varying the reference time of the detection. CONSTITUTION:A timer 280 starts counting on the start of film winding operation by the motor and is reset on the completion of the winding operation. When a gate 332 is inverted positively, the film end is judged and the motor stops. The power source 210 is connected to resistance 306, 308, 310, and 312 and voltages at respective parts are compared with a reference voltage by comparators 314, 316, and 318. When the source voltage is sufficiently high, every comparator output is positive, and when the output of an FF95 is inverted positively, the gate 332 is inverted positively. When the source voltage drops, the gate 332 is inverted by the output of an FF96, and when the source voltage further drops, it is inverted by the output of an FF97, so the time of winding is secured sufficiently.

Title: Heat exchanger
Inventor: MEN MASATO
IPC: F28D15/02
Filed: 1986-02-18
Abstract: PURPOSE:To facilitate starting of a heat exchanger containing an organic heat medium from a cold state by heating the low-temperature portion of the heat exchanger containing the heat medium with a heat exchanger containing water. CONSTITUTION:A high-temperature fluid flows as shown by an arrow 1 and a low- temperature fluid flows as shown by an arrow 2 thereby to form a counter flow. In case where a heat exchanger group is started from a cold state, the vapor of an organic heat medium heated in an evaporator 5 rises up along a rising connecting pipe 6. A liquid of the heat medium produced by a condenser 7 falls along a falling connecting pipe 8. However, since the temperature of both connecting pipes 6 and 8 are still less than the solidifying temperature of the heat medium, the heat medium is cooled and solidified within the pipes. Steam evaporated in an evaporator 9 rises up along the rising connecting pipe 10 almost simultaneously with the evaporation of the heat medium of the evaporator 5. A part of the steam heats the connecting pipes 6 and 8 via a branched pipe 11 thereby to preventing the heat medium from solidifying, and starting is facilitated. When a temperature sensor 13 detects that the temperature of the organic heat medium has become continuously more than the solidifying temperature, a control valve 14 is closed, and the supply of steam for heating is stopped.

With respect to addition or subtraction, the CPU 20 discriminates whether input unit symbols are equal to each other or not to confirm whether the unit calculation is possible or not. Thereafter, the operation result of the unit symbol is obtained with control procedures in the figure by the CPU 20 and is stored in the RAM 22.

Filed: 1982-03-02
Abstract: PURPOSE:To enable adhesion of magnetic head cores having different coeffts. of thermal expansion and guide members consisting of nonmagnetic materials such as ceramics by the use of adhesive agents of glass or the like without generating adhering strains and to reduce the number of adhering steps by making the adhering areas between the magnetic head cores and the guide members small. CONSTITUTION:While a magnetic head assembly 35 is pressed in an arrow direction, the assembly is subjected to glass bonding in a bonding furnace. When the assembly 35 is heated, the glass penetrates into the joint surfaces between a core chip 22 and ceramic chips 27, 31 by the effect of capillarity and adheres these chips because said joint surfaces are finished to specular surfaces. Glass rods 34 packed into the joint surfaces between sliders 33, 34 and the chips 27, 31 melt as well and penetrate in the joint surfaces; therefore, these sliders and chips are bonded as well simultaneously. The adhesion is accomplished simply by slicing a core block to form the chip 22 then adhering the chips 27, 31 to the slight contact surfaces of only the front and rear surfaces of the chip 22; therefore, the adhering area of the chip 22 is small.
