A nondestructive inspection method of inspecting a securing defect of a polymer insulator having an FRP core, an outer cover portion arranged around the FRP core, and at least one metal member secured to at least one end of the FRP core, includes the steps of; measuring an acoustic emission signal generated when the metal member is secured to the FRP core by using compression dies; and determining whether or not the securing defect is generated on the basis of the acoustic emission signal in process. Moreover, the disclosed apparatus performs the nondestructive inspection method mentioned above.

A coefficient indicating the relationship between a measurement voltage of voltage measuring unit and a voltage drop in a drain bias voltage due to drain current is determined based on at least an S parameter of a measuring system and an input impedance of the measuring unit. A voltage drop at the drain is determined from the coefficient. Based on the determined voltage drop, a drain bias voltage actually applied to the drain of an FET is determined. Also, a coefficient for converting the measurement voltage of the measuring unit into a drain current is determined based on at least an S parameter of a measuring system and the input impedance of the voltage measuring unit and an electrical length of the measuring system if necessary. Based on the determined coefficient, a drain current actually flowing in the FET is determined.

A gear selection position displaying device includes a path display portion (56) which displays a movement path of a gearshift lever, lever position display portions (circled portions of 51c, 53b, 53c, 53d and 55b) which display the position of the gearshift lever, and gear range display portions (51a, 52a, 54a and 55a, and symbol imparted portions of 51c, 53b, 53c, 53d and 55b) which display gear ranges which are selected at the gear selection positions, respectively. When a momentary area where the gearshift lever is automatically restored to a home position is selected, a display on the gear range display portions (52a, 54a) which corresponds to the momentary area so selected is deleted (52b, 54b), whereas a gear range corresponding to the selected momentary area is displayed (53c, 53d) on the gear range display portions (53c, 53d).

A shift control system is arranged such that a shift lever 201 is movable to a “P” position, an “R” position, an “N” position, a “D5” position and a “D4” position along a first shift guide path 211, it is movable also from the “D4” position to a “3/M” position along a connection shift guide path 212, and it is movable also along a second shift guide path 213, from the “3/M” position into a direction different from that of the connection shift guide path 212. When the shift lever is shifted to the “D5” position, the transmission is set into an automatic shift control with forward drive speed ratios up to the FIFTH speed ratio. When the shift lever is shifted to the “D4” position, the transmission is set into an automatic shift control with forward drive speed ratios up to the FOURTH speed ratio. When the shift lever is shifted from the “D4” position to the “3/M” position along the connection shift guide path 212, the transmission is set into a “3” range, where an automatic shift control is executed with forward drive speed ratios up to the THIRD speed ratio. Then, the shift lever at the “3/M” position is swiveled along the second shift guide path 213 to shift the speed ratio of the transmission manually in steps.
