Title: Detector
Inventor: MOMOSE SATORU
IPC: H01H1/40
Filed: 1992-05-22
Abstract: PURPOSE:To improve switching reliability upon a detector by establishing the contact condition of a contact brush with a pattern formed in a switch substrate, always close to that of the contact brush established in its early stage of use, with the aid of plural segment-shaped portions formed in the head of the contact brush in such structure that the heads of brush segments may differ in position from one another. CONSTITUTION:A switch substrate is in the shape of a disc composed of an electrically conductive portion 1 and an electrically non-conductive portion 2. A contact brush 4 is formed in its head in such structure as to have plural contacts so as to calculate upon a chattering preventive effect. Although such a contact brush 4 has no problem in the early stage of use, it is worn away at its head to cause the incomplete detection of a pulse by a detector during long use from the viewpoint of durability. In order to solve that problem, the contact brush 4 is reformed in such structure that the plural segment-shaped contact portions formed in the head of the contact brush 4 may be shifted in the vertical direction of the contact brush 4 little by little from one another. This structure enables another brush segment adjacent to one brush segment to establish the contact condition thereof with a pattern formed in the switch substrate, close to that of the contact brush 4 in its early stage of use, so that the detector may secure the ability enough to detect a pulse even if the one brush segment is worn away at its head.

Title: Friction material
Inventor: SUGITA YASUSABUROU
IPC: C08L71/02
Filed: 1982-07-28
Abstract: PURPOSE:To reduce changes in the stepping force by selecting materials with less compression permanent set at high temperatures, and with less difference in hardness at high and low temperatures, as the matrix. CONSTITUTION:A matrix, consisting of at least two different kinds of heat and oil resistant rubber containing copolymer consisting of an allyl glycidyl ether and an epichlorohydrin, is added with a vulcanizing agent together with other additives and carbon black. This composition is further mixed with a metallic oxide to produce heat and oil resistant friction material for wet use. The copolymer consisting of the allyl glycidyl ether and epichlorohydrin is characterized in its special molecular struction, i.e., having double bonds and allyl groups in a polymer, and having double bonds in a polymer allows the copolymer to change in hardness less than the epichlorohydrin. This prevents the matrix blended with basic acrylic rubber from being hardened in high-temperature oil.

Abstract: PURPOSE:To take a measurement stably without being affected by variation in ambient temperature by adding an electric heater and a thermocouple to a load transducer, and setting and controlling the heater temperature by a temperature controller to temperature higher than the ambient temperature. CONSTITUTION:The electric heater 1 and thermocouple 2 are added to the load transducer 3 and the temperature controller 4 sets and controls the heater temperature to the temperature higher than the temperature of ambient environment to hold the transducer 3 at the constant temperature. Further, the heater 1, thermocouple 2, transducer 3, and a ring 5 for load transducer fixation are put in a metallic container 6 to uniform the temperatures of the respective parts of the transducer 3. Further, the container 6 is covered with a heat insulating protection box 8 which has a space 7 to hold the temperature of the transducer 3 more constant and uniform, thereby suppressing the influence of variation in ambient temperature. Then variation in the temperature of the air in a drying chamber is smaller than that of the temperature of the transducer 3, so even if the ambient temperature varies below the set temperature, the transducer 3 itself which is heated and heat-insulated does not vary in temperature. Thus, the measurement is performed stably.
