Abstract: The present invention relates to piperazine derivatives of formulae Ia, Ib, Ic and Id and their use to treat myocarditis. where R1a, R1b, R2, R3, R4, R5, R6, R9, R10 and Y are as defined herein.

Abstract: In a power converting apparatus including a capacitor connected in series which serves to divide a DC voltage, and a PWM inverter bridge for converting the DC voltage into an AC phase voltage having three electric potentials of a positive voltage, a negative voltage and an intermediate voltage in a plurality of phases, a zero voltage period generator (11) is switched by signal switching devices (5 to 10) when a load current reaches a first overcurrent level based on the detection of an overcurrent detector (12), and there is provided a zero voltage period having an intermediate voltage in which output phase voltages having all phases of the power converting apparatus become the intermediate voltages, thereby carrying out a current limitation. With an inexpensive structure, consequently, a rapidly increased current in an inverter can be instantaneously suppressed at time of the detection of an overcurrent.

The transmission cylinder is rotatable about an axis and is coupled with the crankshaft of the engine. The pump swashplate is rotatable and disposed at an angle to the axis of the transmission cylinder and is coupled with pump plungers. A motor swashplate which is variably inclined relative to the axis of the cylinder and includes motor plungers associated with the cylinder.

Abstract: A storage battery including a container and a cover. The container is partitioned into a plurality of cell chambers by a plurality of partition walls. Each cell chamber has a cell therein which is composed of positive and negative plates. The negative and positive plates are connected by negative and positive straps, respectively. An intercell connecting conductor connects negative and positive straps from adjacent cells through an opening in the partition wall. Each intercell connecting conductor includes a horizontal base attached to one of the straps, and an ear which extends obliquely upwardly from the base to the opening in the partition wall. The opening in the partition wall and the ear are laterally offset from the base so that they are vertically unaligned with the base.

Abstract: A pair of right and left main pipes and or a pair of right and left down tubes, or a main pipe and a down tube are formed of one piece of continuous pipe material with its intermediate portion warped. The head pipe has a supporting surface portion corresponding to the surface of the aforementioned warped intermediate portion. This supporting surface portion is integrally cast together with a tubular main body portion of the headpipe. The warped intermediate portion of the pipe material is fixed to the supporting surface portion of the head pipe by welding. According to the present invention, the constructions and shapes of the welded portions are simplified. Thus, the invention is best suited to robot welding in order to improve productivity. Also, the head pipe is formed at its front surface or its both sides of its tubular main body portion with an opening in order to reduce the weight.

Abstract: An internal combustion engine is provided which comprises an outside member including a cylinder block section and a crankcase half section which are both casted into a single body, the crankcase having an opening formed therein which has an opening edge arranged in an inclined relationship to the center axis of a cylinder and also to the center axis of a crankshaft, and a crankcase half having a corresponding opening edge thereon for covering the opening of the crankcase half section.The inclined opening of the crankcase half section facilitates working of the inside of the crankcase half section and the cylinder block section and assembling of internal parts within the outside member.

Abstract: In an engine of the type having opposite side wall portions more or less differing from each other in rigidity, as in a so-called side valve engine, the axis of the piston unit is set at such an angle of inclination relative to the axis of the associated cylinder bore that the two axes substantially coincide with each other in the power or explosion stroke of the engine cycle when the cylinder block is tilted, under the tensile load acting on the engine structure, on account of the differential rigidity of the opposite side walls thereof. With this axis arrangement, an uneven wear of the mating bearing surfaces of the piston and cylinder and of the crankpin and bore in the large end of the associated connected rod is effectively prevented.

Abstract: A recoil type starter device for an internal combustion engine is provided which includes a starting pulley fixed at one end of the engine crank shaft and having a plurality of openings in its circumferential side surface; and a rotatable rope pulley confronting the starting pulley and mounted on a separate fixed shaft, said rope pulley having a pawl to engage any of the openings of the starting pulley to transmit rotational force of the rope pulley to the starting pulley at the start of the engine, a spiral spring to take up the starting rope around the periphery of the rope pulley after start of the engine, a disc fixedly mounted on the shaft of the rope pulley, and a U-shaped wire spring, one end of which is connected to a spring fitting part on the pawl, and the other end of which is frictionally contacted around the circumference of the stationary disc.
