Abstract: ABSTRACT OF THE DISCLOSURE    In a starter for internal combustion engines, a tubular pinion gear support shaft 8 is rotatably supported by a casing, and coupled to a drive shaft of a motor so as to be rotatively driven by the motor, and an annular pinion gear 3 is fitted on the pinion gear support shaft in axially slidable but rotatively drivable relationship.  A push rod 9 is axially slidably received in the tubular pinion gear support shaft and provided with a free end engaged with a free end of the pinion gear for transmitting a shifting force for driving the pinion gear into meshing with a ring gear of an engine from a shift lever to the push rod.  A shift spring 15 consisting of a compression coil spring is coaxially received in the pinion gear support shaft and interposed between an associated end of the shift lever and a base end of the push rod. Thus, the assembling of the starter is simplified while the action of the shift spring is stabilized, and the design of the starter is made compact.

Title: Medical stimulator with operational amplifier output circuit
Inventor: HUDRLIK TERRENCE R
IPC: A61N1/32
Filed: 1991-07-29
Abstract: A medical electrical stimulator employing an operational amplifier output circuit (26) for producing an electrical stimulating pulse for application to body tissue and for sensing electrical activity in the body tissue. A first input (22) to the operational amplifier is coupled through a virtual load (104) to a probe electrode in close proximity to the body tissue. The second input (24) is coupled to a second electrode which may be remote from the tissue to be stimulated. A defined voltage signal may be provided to the second input to the amplifier, and the amplifier correspondingly delivers current through the virtual load (104) to the probe electrode as the amplifier maintains equal voltage levels at its two inputs. The current delivered to the probe electrode functions to stimulate the body tissue. By varying the defined voltage signals provided to the second input of the amplifier, arbitrary stimulation pulse waveforms may be generated. After termination of the defined voltage signal, the amplifier functions to restore the electrode-tissue system to its previous electrical equilibrium condition and to sense induced or spontaneous electrical activity in the tissue. The circuit may be employed in cardiac pacemakers, with the probe electrode located on or in the heart, or in other electrical medical stimulators.
