Title: Brake pad
Inventor: MIZUKOSHI HIROYUKI
IPC: F16D65/092
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To reduce the squeak of which the rate of generation is increased when the past history and abrasion of a frictional material are advanced to some degree, by mounting an inner hole extended in parallel with a surface of the frictional material, under the surface slidably contacted with a counter rotor of the frictional material. SOLUTION: A brake pad 1 is formed by a steel iron back plate 2 and a frictional material 3 integrally bonded to the back plate 2. The frictional material is provided with an inner hole 4 extended at an inner peripheral side and an outer peripheral side in parallel with a surface of the frictional material 3 at a central position of the back plate 2. The inner hole 4 is a thorugh hole penetrating through an inner peripheral end surface and an outer peripheral end surface of the frictional material 3. A diameter of the inner hole 4 is preferably within a range of 1/4 through 1/3 of a thickness of the frictional material 3. By applying this structure, the braking squeak reduction effect can be obtained by a reiriforcement material and the blending of a friction adjusting agent in an initial period of the use of the frictional material 3.  When the abrasion is advanced over the upper depth of the inner hole 4, and the inner hole 4 is exposed to the surface, the squeak reduction effect similar as that obtained when a groove is formed on the surface of the frictional material 3 can be obtained.

Filed: 1992-12-08
Abstract: PURPOSE:To achieve lower temperature soldering upon packaging a substrate by forming at least an outermost layer of an external electrode provided on both ends of chip type electronic parts with metal having solid phase wire temperature being less than a specific value. CONSTITUTION:An external electrode 13 comprises silver Ag or an alloy Ag-Pd and is baked such that an internal electrode 11 communicates with an end portion of a chip 12, to form an electrode body 14. Nickel Ni is used so as to cover the outer surface of the electrode body 14 to form a protective layer 15 by making use of electrolytic plating or electroless plating. Metal having solid phase temperature being 183 deg.C or lower is used so as to cover the outer surface of the protective layer 15 to form an outermost layer 16 by making use of electrolytic plating or electroless plating or dipping. Hereby, packaging of chip type electronic parts is achieved with low temperature soldering to eliminate a thermal affection to other parts packaged on the substrate and to the substrate itself and hence it is possible to deal with high density packaging.

Title: Filling pump and method for cleaning the same
Inventor: TAKISHITA MOTONORI
IPC: F04B15/02
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a filling pump wherein the inside of the filling pump can be cleaned with a small quantity of detergent liquid and the filling pump can be cleaned in a short time. SOLUTION: At the time of rough cleaning, detergent liquid normally flows from a suction flow path 4 to a discharge flow path 4. On the other hand, at the time of full cleaning, an ultra-hard ball 22 of a discharging check valve 20 is floated by a discharging magnet 25 to open the check valve 20 at the time of drawing out a piston 18, thereby sucking the detergent liquid into an oil layer 6 through the discharge flow path 4. Then at the time of pushing in the piston 18, an ultra-hard ball 12 of a sucking check valve 10 is floated by a sucking magnet 15 to open the check valve 10, thereby discharging the detergent liquid in the oil layer 6 through the suction flow path 2. That is, at the time of full cleaning, the detergent liquid flows reversely from the discharge flow path 4 to the suction flow path 2 to efficiently substitute the detergent liquid for residual liquid in the filling pump.
