Abstract: A non-asbestos friction material is made by molding and curing a composition which includes a fibrous base other than asbestos, a binder, an organic filler, an inorganic filler and an abrasive. The abrasive is composed of one or more inorganic substance selected from among inorganic substances having a Mohs hardness of at least 4.5 and inorganic substances having a Mohs hardness of less than 4.5 and containing at least 50 wt % of a component having a Mohs hardness of at least 4.5. The total amount of organic substances and the total amount of abrasive are in a volumetric ratio of from 1.5/1 to 3.5/1. The friction material thus constituted generates little squeal or other undesirable noise and has a good wear resistance.

Abstract: A method of producing a friction component of a multilayer structure in which each layer can be formed so as to have a specified thickness. The method includes the steps of: using a slide plate having a void of a predetermined shape formed therein in such a way that an output port is open over the void in the slide plate, moving the slide plate in the horizontal direction to allow the output port to be used as a leveling plate to sufficiently fill the void with the powdery material, moving the void beneath a molding box, feeding a predetermined amount of final powdery material into the molding box; and executing either pressurization or a combination of pressurization and heating between a plunger and a fixed mold to temporarily mold or mold a friction component of a multilayer structure.

Abstract: To provide a friction component of a multilayer structure in which each layer can be formed so as to have a specified thickness, as well as its manufacturing apparatus and method. A side plate 3 having a void 3a of a specified depth formed therein is provided between a plunger 2 and a fixed mold 5 so as to move in the horizontal direction. A hopper 6 for adhesive-layer materials is provided near a molding box 1. An output port 6a in the hopper is located so as to contact slide plate 3. When the side plate 3 is moved in the lateral direction in the figure so that the void 3a is located under the hopper 6, the lower end surface 6b of the hopper acts as a leveling plate to feed an adhesive-layer material 8 into the void. The adhesive-layer material is moved to the lower part of the molding box 1, a specified amount of friction material 9 is fed in such a way that its thickness becomes uniform, and the plunger is then used to pressurize and mold the materials.

Abstract: A driving slope of a disengaging member of a terminal removing jig is pushed into a gap between an electric contact portion of a metal terminal and a disengaging free end part of a cantilever-like flexible engagement portion of a connector housing so that the engagement part of the flexible engagement portion is pushed up. The jig is then pushed inward further so that a butting surface of a pushing member of the jig is put into contact with the front end of the electric contact portion of the terminal to move it back out of the connector housing. Therefore, it is possible to dispense with pulling out a metal terminal from a connector housing with a hand, to make it easier to remove the terminal from the housing out of it.
