when he was not in custody, did not preclude questioning by the detective and the
lieutenant when they arrived at the scene a couple of hours later to interrogate him.
       As recounted above, the detective informed defendant of his rights to remain silent

his right to a lawyer and all further questioning should have ceased immediately. We
disagree and conclude he never clearly and unequivocally invoked his right to counsel.
To the contrary, despite his nervousness and his allusions to an attorney, defendant
objectivelyIn recent years, an HEV (Hybrid Electric Vehicle) developed for the purpose of protection of environment and improvement of performance has come into wide use. The HEV is equipped with two drive sources such as an engine and a motor, and an inverter which converts a direct current of a secondary battery into an alternating current to supply the alternating current to the motor. In the HEV, it is necessary to cool the motor and the inverter, in addition to an existing engine cooling system. Accordingly, the conventional HEV has a cooling circuit for cooling an engine (an engine cooling circuit) and a cooling circuit for an HEV system (an HEV cooling circuit), and thus cools the engine or the HEV system by circulating coolant in the associated
