Abstract: A blood pressure monitor includes a main body provided with a power switch and an inflating switch, a cover mounted on the main body in an open-and-close fashion and on an inner wall thereof provided with a display, and a cuff secured to the main body as a single unit. When the cover is closed during not using the monitor, the power and inflating switches are covered with the cover. When the cover is opened for use, the display appears. Thus, the blood pressure monitor provides avoidance of unexpected actuation of the power and inflating switches, improvement of operation of the switches and a view angle of the display, improved assembling work of the monitor, and simplification of repair and replacement in the monitor.

Abstract: A NAND bus interface independently receives 16 ready/busy signals from 16 flash EEPROM chips and thereby separately manages the operating states of these flash EEPROMs. Once a flash EEPROM as a write access target is set in a ready state, a write access to this write access target flash EEPROM is started without waiting for completion of the operations of all the flash EEPROMs. Each flash EEPROM is of a command control type capable of automatically executing a write operation. This allows parallel processing of the flash EEPROMs, i.e., a write access to a given EEPROM can be performed while a data write to another flash EEPROM is being executed. An ECC calculating circuit calculates a data string transferred in units of 256 bytes from a data buffer by a processor, and generates an ECC corresponding to that data string. The 256-byte data string is added with the generated ECC and transferred to a data register of a flash EEPROM.

Abstract: An improved process for the production of 5-amino-1,2,4-thiadiazol-3-yl-(2-(lower)-alkoxyimino)acetic acids starting from 5-substituted- or unsubstituted-3-amino-isoxazole compounds is disclosed herein. The title compounds are useful as acylating agents for the production of 7-acylaminocephalosporins.

Abstract: The inlet and outlet passages communicating with a water-cooled engine oil cooler for a vehicle, such as a motorcycle, are arranged for bypass of a regulated amount of oil from the inlet passage to the outlet passage to enhance the flowability of the cooled oil. Provision is made for a replaceable flow control orifice between the oil inlet and outlet passages to regulate oil viscosity. Also described is an arrangement providing for mounting the cooler to the crankcase or oil pan surface whereby air flowing past the cooler during movement of the vehicle assists the effects of the cooling liquid.

Abstract: A valve drive system including mechanisms for varying the timing and lift of intake and exhaust valves in internal combustion engines. In one embodiment, an intake camshaft support member and an exhaust camshaft support member are separately mounted to pivot about axes relative to intake and exhaust rocker arms. The support members include concentric mountings along which the support members together with the cams mounted therein move to selectively advance and retard the valve timing and vary the valve lift. In other embodiments, the camshaft support is unitary in construction for both the intake and exhaust valve train. A variety of adjustments are possible with the several configurations including intake valve closure before bottom dead center during partial load operation.

Abstract: A vehicle engine, particularly adapted for motorcycle application, includes a housing structure in which the cylinder block, the crankcase and the transmission case are integrally formed and openings are provided in separate, angularly displaced walls of the housing for accessing the crankcase and transmission case respectively to permit the crankshaft and the transmission to be independently installed or demounted with respect to each other. Also, the detachable cover for closing one of the side openings of the housing is formed as a stopper for preventing axial disengagement of the starter apparatus ring gear from the crankcase.

Abstract: In order to reduce the space requirements of an internal combustion engine the starter apparatus therefor includes an axially elongated intermediate gear shaft containing gears at each end, one of which meshes with the starter motor pinion and the other of which meshes with the ring gear on the crankshaft.

Abstract: In order to prevent inordinate thermally-induced backlash between the drive and driven gears of the timing transmission of an internal combustion engine, an idler gear between the drive and driven gears is rotatably carried by a support plate having one end connected to one of the engine crankshaft or camshaft and its other end connected to the engine body by a connection adapted to accommodate relative thermal expansion between the support plate and the engine body.

Abstract: An oil pump organization for an internal combustion engine is described in which the pump rotor is operatively connected to a transmission gear shaft in order to eliminate the need for a pump drive shaft and to thereby reduce engine space requirements.

Abstract: A cam shaft driving device for an engine which is adapted to operably associate a cam gear located on a cam shaft of an upper portion of an engine body with a driving gear on a crank shaft of a lower portion of the engine body, with this association being effected through the intermediary of a cam idling gear. In this device, first and second wall portions, mutually displaced along the axis of crank shaft rotation of the engine and projecting outwardly and laterally from both sides of the engine body, provide a receiving space. This receiving space is provided between adjacent cylinders in the engine body and is larger in laterally extending width than a diameter of the cylinders, with this width extending laterally of the cylinders and transversely of the axis of rotation of the crank shaft. A single gear holder is located in said receiving space, with this gear holder being mounted on at least one of the wall portions.

Abstract: An engine employing multiple valves which are mutually inclined. A valve actuating assembly includes two camshafts. Primary rocker arms are driven by the camshafts and in turn drive secondary rocker arms. The secondary rocker arms are pivotally mounted about common shafts and extend to the valves. The common shafts are located between the valves.

Abstract: A multi-cylinder internal combustion engine comprising: first and second crankshafts disposed apart from and parallel with each other; first and second pistons operatively connected to the first and second crankshafts through connecting rods, respectively; and first and second cylinders for slidably accommodating therein the first and second pistons, respectively, both the crankshafts being interlocked with each other to rotate synchronously, the first and second cylinders being disposed adjacent to each other in the axial directions of the crankshafts. Vibrations due to the primary inertial force can be eliminated or alleviated without using a special balancer shaft. The size and weight of the engine are greatly reduced as compared with a conventional horizontally opposed type or V type engine.

Abstract: A three- or four-wheeled motor vehicle such as a buggy includes a rear fork composed of first and second rear fork members having front ends pivotally mounted on a frame and rear ends supporting rear wheels, respectively, an axle housing having first and second axial ends, the first axial end being joined to the rear end of the first rear fork member, a rear axle rotatably supported in the axle housing, a gear case coupled between the rear end of the second rear fork member and the second axial end of the axle housing and accommodating a gear mechanism for driving the rear axle, and at least one cross member extending between and joined to the first and second rear fork members.

Abstract: A breather passage is provided to perform breathing function for both two casings, one being a first casing housing therein a power-transmission means and the other being a second casing housing therein a gear-transmission mechanism. The breather passage is defined between interfacing surfaces of a main body and a cover those providing the second casing. A gasket is interposed between the main body and the cover so as to devide the breather passage into two passages. The breather passage has one end formed with a first breather hole opened to an atmosphere and the other end formed with a second breather hole opened to an interior of said second casing. The breather passage is further formed with a branch passage at the position rearward from said second breather hole to permit liquid communication between an interior of the first casing and the atmosphere.
