Filed: 1985-04-15
Abstract: PURPOSE:To mount gold on the bonding part of a lead frame easily and securely by a method wherein electric energy is applied between a capillary and the lead frame and a gold ball part is applied to the lead frame by resistance welding. CONSTITUTION:The protruded free end 21 of a gold wire 2 inserted through a capillary 1 is subjected to electric discharge machining by a discharge electrode 3 to form a gold ball part 22 at the tip of the gold wire 2. then the capillary 1 is made to descend and the gold ball part 22 is pressed against a lead frame 4 by the tip of the capillary 1 and, at the same time, a current application circuit 6 is turned on to apply a current (a) between the capillary 1 and the lead frame 4 to carry out resistance welding. With the resistance welding of the gold ball part 22 as described above, the gold ball part 22 is easily bonded to the lead frame 4 in an atmosphere of the normal temperature. By monitoring the feedback circuit of a welding power source, bonding strength is easily controlled. A gold part 23 is cut off from the gold wire 2 by clamping the gold wire 2 in the midst of ascend of the capillary 1.

IPC: H03H3/08
Filed: 1979-06-25
Abstract: PURPOSE: To make it easy to split a transducer electrode without deteriorating frequency characteristics by composing electrode fingers, adjacent to a split part of  stepped electrode fingers or bent electrode fingers and differing in potential from  each other.  
     CONSTITUTION: At split D, bent electrode finger 12 is provided on one side and stepped electrode finger 13 on the other; bent part 12a and step part 13a are arranged at an interval of λ/8, and coupling parts 12b and 13b extending to common parts 14 and 15 at 5λ/8. Then, a vibration source, formed between step part 13a and bent part 12a as mush as the insufficiency of a vibration source between bent part 12a and auxiliary electrode finger 4c', performs excitation. Since the interval between coupling parts 12b and 13b is wide, excitation is extremely small. In the constitution like this, electrodes of a transducer can be split in the propagation direction of an elastic surface wave while maintaining the same vibration source as before the splitting without deteriorating the frequency characteristics.

Title: Element for measuring concentration of oxygen within melted metal
Inventor: NARAHARA TAKUMI
IPC: G01N27/411
Filed: 1991-03-20
Abstract: PURPOSE:To enable a stable measurement to be made without any release of a film layer or generation of cracks when dipping in a melted steel by mixing a powder with two types of grain size distributions with an oxide containing a fluoride for forming the film layer. CONSTITUTION:A film layer 2 is provided on a surface which contacts a melted metal on an outer-periphery surface for a solid electrolyte 1 consisting of zirconia. This layer 2 is an oxide containing fluoride and is formed by mixing a powder with two types of grain size distributions and a filling density of the powder can be increased and the intricate layer 2 can be formed since small particles fill a gap of large particles. Therefore, by reducing sintering shrinkage, release of the layer 2 or generation of cracks can be reduced. Also, an amount of added fluoride with a binding effect within high temperature can be suppressed to a small amount owing to their reduction and a melting point of the layer 2 can be increased, thus preventing expansion or melting of the layer 2. Therefore, a stable measurement can be made.

Title: Method and apparatus for measuring specific surface area of extremely fine particle and powder
Inventor: SAWA YASUHISA
IPC: G01N21/79
Filed: 1991-03-22
Abstract: PURPOSE:To improve analysis accuracy by stirring cetyl trimethyl ammonium bromide (CTAB) aqueous solution and extremely fine particles and power, inserting a photometric titration sensor at the center of filtered solution and performing titration wherein constant permeability set in a specific range is an end. CONSTITUTION:CTAB aqueous solution and an appropriate amount of extremely fine particles and power are sufficiently stirred, the filtered solution is taken in a titration vessel 8 and a rotator 9 is rotated, flocks are combined while rotating to be large-sized flocks. If a photometric titration sensor 2 is put to the center of the vessel 8 which is not likely to be influenced by the large-sized flocks, light emitted from a lens 10 is led through a reflecting mirror 3, the lens 10, a polarizing filter 7 to a detector 7. If the CTAB solution is suspended in white at this time, light permeability between the lens 10 and the reflecting mirror 3 drops, but measuring the permeability at the center of the vessel 8 ensures stable measurement. In addition, by performing titration with constant permeability set in a range of permeability of 3 to 30% as the end, analysis accuracy can be improved.
