    Abstract: A system for regulating the idle speed of an internal combustion engine. The engine has an alternator, and a voltage regulator having a Darlington circuit connected between an end of a field winding of the alternator and the ground. The Darlington circuit is responsive to the output voltage of the alternator for controlling the current flowing a field winding of the alternator so as to regulate the output voltage of the alternator. The system has an integrator for integrating the voltage across the Darlington circuit and a comparator for comparing the output voltage of the integrator with a reference voltage and for producing an output voltage dependent on the comparison.A solenoid is operatively connected to a throttle valve of the engine.A switching transistor circuit is provided to respond to the output voltage of the comparator for allowing the current to pass through the solenoid and for actuating the throttle valve to regulate the idle speed.

    Abstract: An abnormality diagnosis device of a thermostat includes: a temperature detection module that detects a temperature of cooling water on the basis of a sensor signal of a cooling water temperature sensor; an abnormality determination module that detects an abnormality of the thermostat, when the temperature of the cooling water reaches a first reference temperature and thereafter becomes lower than an abnormality determination reference temperature that is lower than the first reference temperature; and a cooling water temperature adjustment module that executes a control for preventing temperature decrease of the cooling water, when the temperature of the cooling water reaches the first reference temperature and thereafter becomes lower than a second reference temperature that is lower than the first reference temperature and is higher than the abnormality determination reference temperature.

    Abstract: According to one implementation, a laser peening processing device includes a laser peening processing device includes a laser oscillator, a nozzle and an inclining structure. The laser oscillator emits laser light. The nozzle condenses and irradiates the laser light toward a surface to be processed of a workpiece, with injecting liquid toward the surface to be processed. The inclining structure inclines at least one of the nozzle and the workpiece to make an injection direction of the liquid be different from a normal direction of the surface to be processed. The air bubbles arising by at least one of collision between the liquid and the surface to be processed and shock by irradiation of the laser light on the surface to be processed are flowed in a direction depending on an inclined direction of the surface to the injection direction of the liquid.

    Abstract: A vehicle includes a battery, a charging unit, and a cable groove. The charging unit has a charging cable and a charging gun provided at one end of the charging cable and is configured to supply power to the battery from an external power supply. The cable groove is provided in a vehicle body and capable of accommodating the charging cable. When the charging cable is accommodated in the cable groove, the charging gun is disposed on an outer side of a transmission path, through which a shock load is transmitted to the battery during a collision with an external object.
