Title: Wire bonding equipment
Inventor: KOMAKI YUJI
IPC: H01L21/60
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To stably form a ball at the tip of a wire while surely preventing oxidation of a lead frame, by installing a linkage path linking a carriage space with the open air around a bonding work window formed in a cover. SOLUTION: As an exhaust path of anti-oxidizing gas supplied to a carriage space 18 of a lead frame 1, a linkage path 21 is installed in addition to a bonding work window 17A. Thereby the exhaust path of gas is dispersed, and a gas spouting amount from the bonding work window 17A can be decreased, without reducing the supply amount of the anti-oxidizing gas. As a result, a flow of gas around a torch electrode 14, in particular, turbulence can be restrained. Thereby a ball 3A of a wire 3 in a fused state during discharge is prevented from being swung by the flow of gas and deformed. It can be avoided that the ball 3A hardens in the swung state or the deformed state as it is and becomes an eccentric ball or a deformed ball.

Abstract: PROBLEM TO BE SOLVED: To always keep the energizing force of an energizing means adequate by integrating the rotating quantity of an adjusting motor for adjusting the energizing force of a resistance plate, detecting the position of energizing means or energizing means moving member and driving this adjusting motor only when these means are judged to be within a set range. SOLUTION: A lifting rod 17 is moved to an initial position to impart the prescribed energizing force on the resistance plate 4 at the time of starting the operation of a rice milling machine. Namely, the driving time of the adjusting motor 18 is measured and the position of the lifting rod 17 is recognized after the lifting rod 17 reaches the lower limit position. Next, the actual current value of a driving motor 5 is measured and the time for driving is calculated by revolving the adjusting motor 18 forward or backward in such a manner that the measured current value coincides with the set current value. The lifting rod 17 is vertically moved by driving the adjusting motor 18, by which the energizing force of the resistance plate 4 is adjusted only when the lifting rod 17 is judged to be confined within the range from the upper limit position to the lower limit position in the case of driving the adjusting motor.

Title: Exhaust gas filter
Inventor: FUKUNAGA TAKASHI
IPC: B01D46/00
Filed: 1985-12-24
Abstract: PURPOSE:To obtain the titled filter having high mechanical strength by making density of a material in a rear part of a closed part of an outlet for exhaust gas of a ceramic honeycomb-shaped filter higher density in comparison with the part excepted from this rear part. CONSTITUTION:The titled filter is constituted by closing alternately the end parts of the cells 5 of a porous ceramic honeycomb structural body in an inlet part and an outlet part. An outlet reinforced part 15 is formed by constituting the filter so that density of a material in a rear part of a closed part of an outlet for exhaust gas of the filter is made to higher density in comparison with the other part. Therefore when burning the collected grains, resistance to cracking properties sufficient in practical use is exhibited and also cracking properties sufficient in practical use is exhibited and also sufficient strength is obtained for shear fracture or the like due to the pressure of the exhaust gas. Also similarly breakage of the inlet part due to the collision of the fine grains contained in exhaust gas can be prevented by increasing density of the material of the inlet part of exhaust gas.

Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To perform the work of an excellent grading property by limiting the vertical movement of a work machine at the time of the shift operation of a speed change gear in a tractor provided with plowing depth control and load control. SOLUTION: Based on the detection value of an engine rotation number sensor 16, the change rate of an engine rotation number is computed in a controller. Corresponding to a set plowing depth value inputted by a plowing depth setting dial 31 beforehand, the controller decides the lower limit value of the engine rotation number and the stipulated value of the change rate of the engine rotation number beforehand and outputs a work machine elevation command to a solenoid 41 for elevation when the engine rotation number becomes less than the lower limit value when the load control is executed.  When the controller judges that the shift operation of the speed change gear is present by the detection value of a shift position sensor 40, until fixed time elapses from the shift operation, the stipulated value of the change rate of the engine rotation number is changed and set to a value larger than normal.

IPC: B28B1/16
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To dispense with an operation to pour a joint filler into a form for a concrete product with a decorative sheet and thereby upgrade the manufacturing efficiency. SOLUTION: A soft packing material which is wider than a joint is bonded to the joint part of a decorative sheet on the inner face of a form face forming a face in which the decorative sheer is imbedded. In addition, air holes are formed penetrating each of the regions surrounded by the packing material of the form face. On the outer face of the form face, a vacuum chamber is formed covering all the air holes. The decorative sheet is placed on the packing material and the vacuum chamber is set in a vacuum state. Consequently, the decorative sheet is sucked onto the form face and the packing material is deformed to form the shape of the joint part, so that a joint filler need not be poured into the form.

Abstract: PROBLEM TO BE SOLVED: To suppress the jamming of an organic silver salt dispersion in a dispersion passage and to obtain an organic silver salt dispersion having good dispersibility of the organic silver salt by preliminarily dispersing a stock fluid one or more times and then carrying out conclusive dispersion. SOLUTION: High pressure comminuting parts 1 and 2 disposed in a high pressure homogenizer are regions in which a passage for a stock fluid which passes the dispersing apparatus are curved at about 90 deg. angle.

The stock fluid consisting of the organic silver salt, silver halide grains, a solvent and a binder is preliminarily dispersed one or more times and then conclusive dispersion is carried out. The diameter of the passage used in the preliminary dispersion is made larger than that of the passage used in the conclusive dispersion.  The blocking of the passage duet to the jamming of the dispersion in the passage is not caused in the conclusive dispersion and the objective organic silver salt dispersion having good dispersibility is obtained.
