Patent number: 4457185Abstract: A rotational speed number controlling device for automatic transmissions for changing speeds by automatically changing a plurality of centrifugal clutches in response to the number of revolutions of the engine wherein a sliding piece is connected to a rotary shaft to which the rotation of a low speed side centrifugal clutch is to be transmitted so as to be able to transmit rotations and to be slidable in the axial direction in response to the driving torque so that the number of engaging rotations of a high speed side centrifugal clutch may be varied by the sliding of the above mentioned sliding piece caused in response to the driving torque. For example, in the case of a quick acceleration at the time of the second speed running in an automatic three-speed transmission, the high speed side centrifugal clutch may not be immediately engaged but the second speed state may be maintained until a sufficient acceleration and then the high speed side centrifugal clutch may be engaged.Type: GrantFiled: July 29, 1981Date of Patent: July 3, 1984Assignee: Suzuki Motor Company LimitedInventors: Hitoshi Yoshida, Seiichi Suzuki

Patent number: 4415195Abstract: Automobile windows on both sides of the vehicle are curved inwardly and arcuately toward the top of the compartment and are made separate from the doors and slidably abutted at least at the front edges on the support frame for the windshield, at least either of the side windows being made openable by sliding them upwardly. When opened, they are accommodated in recesses formed for that purpose in the roof that covers a middle part of the ceiling space above the car body. Alternatively, the windows extend toward each other until their upper edges overlap along the central longitudinal line of the ceiling space above the car body, the windows being made slidable relative to each other, one over the other in a superposed relation, so that either window, when opened, is partly or fully superposed, as desired, parallelly over or under the other.Type: GrantFiled: April 13, 1981Date of Patent: November 15, 1983Assignee: Suzuki Motor Company LimitedInventors: Akira Furukawa, Minoru Araki, Hideyuki Genma

Patent number: 4085010Abstract: A process and an apparatus for powder-dispersed composite plating in which a plating solution is recycled while a pulverulent material contained is being uniformly dispersed therein, and a plating tank is located in the recycling circuit, so that a uniform composite-plated coating is formed on an object or objects to be plated, while the consumption and dilution of the ions in the bath are being avoided by the constant renewal of the plating solution due to the recycling. This arrangement permits attainment of the highest possible plating efficiency through the use of an increased current density. Moreover, the particle size and concentration of the pulverulent material mixed in the plating solution can be controlled and thereby improvements in both plating quality and productivity can be achieved. In the case where the objects to be plated are cylinder- or ring-shaped or flat pieces, they can be stacked up in a cylindrical formation and compositely plated altogether to attain a remarkably high productivity.Type: GrantFiled: January 2, 1976Date of Patent: April 18, 1978Assignee: Suzuki Motor Company LimitedInventors: Shigeru Ishimori, Shinichi Honda

Patent number: 3995875Abstract: A tricycle having unique rear-wheel suspension means is provided. The rear-wheel suspension means includes a rear frame rotatably bearing two rear wheels. The rear frame is disclosed with a connection shaft perpendicularly thereto substantially at its central portion. The connection shaft is rotatably inserted into a cylindrical boss which is provided adjacent to the end portion of the main frame of the tricycle such that when the connection shaft is inserted into the boss and when the tricycle is normally put on the ground, the extension of the axis of the shaft passes through a certain point below the ground contact point of the front wheel.Type: GrantFiled: September 9, 1974Date of Patent: December 7, 1976Assignee: Suzuki Motor Company LimitedInventor: Hiroshi Wada

Patent number: 3981781Abstract: In a method for electrolytically forming on a metal surface a composite coating having improved hardness and wear resistance, a compound containing phosphorous is added into the plating electrolyte, with the phosphorous content being in a quantity of between about 0.1 to 4.2 g/l with minute particles of a required property suspended therein thereby to coprecipitate a nickel phosphide together with the minute particles, whereby the physical and chemical properties of the composite coating are remarkably improved.Type: GrantFiled: August 9, 1974Date of Patent: September 21, 1976Assignee: Suzuki Motor Company LimitedInventors: Yasunobu Mori, Shinjiro Otsuka

Patent number: 3945893Abstract: Fine particles of a very hard material such as silicon carbide and either a solid lubricant such as carbon fluoride or a lubricant such as a powdered organic high polymer are dispersed in a metal plating solution, and a metal object to be plated is immersed as a cathode, together with a metal rod as an anode, in the plating bath, and then a suitable current is passed through the bath to cause coprecipitation of the fine particles and lubricant in the metal deposit. The plated coating layer thus obtained is electro-polished or chemically or mechanically polished and a given thickness of the metal layer is removed to leave the fine particles as tiny protrusions from the lowered surface. In this way a low-abrasion surface is produced on the metal object.Type: GrantFiled: December 27, 1973Date of Patent: March 23, 1976Assignee: Suzuki Motor Company LimitedInventors: Shigeru Ishimori, Shinjiro Otsuka
