Abstract: An objective is to provide a pressure-contact type rectifier in which solder that increases the environmental load is not used, and neither burning nor breakage of a rectifying device occurs, even if temperature of the rectifying device increases due to current flowing or force towards outside the rectifying device is applied to a lead end, etc. By providing an electrically conductive friction reducer on at least one electrode face of the rectifying device, the temperature increase can be prevented, and the friction at the contact face can be reduced. Moreover, by providing a flexible portion on the lead end outside a cap, and fixing the flexible portion to the cap, the contact area between the lead and the rectifying device can be kept constant. As a result, a pressure-contact type rectifier in which neither burning nor breakage of the rectifying device occurs can be obtained.

Abstract: An improved fuel injection control apparatus, in which a reference pressure is provided to a pressure regulator, for simplifying the fuel supply system by preventing the fuel quantity injected from injection valves into an engine from being influenced by variations in the air intake pressure. A pressure regulating device disposed in a fuel supply pipe between a fuel pump and the fuel injection valve regulates the pressure of fuel supplied from the fuel pump to the fuel injection valve so that the pressure is proportional to the predetermined pressure, without returning fuel from the injection valve to the fuel tank. An intake pressure detecting device detects the pressure in the intake pipe, and a fuel injection quantity correcting device corrects the fuel injection quantity according to deviations of the fuel pressure regulated by the pressure regulating device from a proper value due to the differential pressure between the pre-determined pressure of the pressure regulating means and the intake pressure.
