Abstract: A NAND flash memory according to an embodiment includes a memory array, a detection circuit, and a drive circuit. The drive circuit is a circuit for driving a plurality of linearly arranged memory cells through a linear word line connected to the plurality of memory cells. The drive circuit has a function of generating a drive voltage in which a pre-pulse having a predetermined amplitude value is set at a timing corresponding to rising of a voltage signal, which rises stepwise by a voltage value, and applying the drive voltage to the word line and a function of detecting a voltage value at a predetermined position of the word line and setting a time width of the pre-pulse according to the detected voltage value.

Abstract: A reflection type sensor includes a light emitting element configured to emit light, a light receiving element configured to receive reflected light from a scale having a pattern, and a transparent member configured to cover the light emitting element and the light receiving element. A predetermined condition is satisfied.

Abstract: An engine starting device includes: a portable unit including a transmitting unit capable of transmitting an ID code inherent to a vehicle; a control unit having a substrate on which a receiving unit receiving the ID code, and a determination unit configured to determine whether the received ID code is a pre-registered legitimate ID are formed; a main body part including an operation knob rotationally operated between an off position and an on position, and fixed between a bar-shaped handle and a speed meter of the vehicle; and a regulation unit configured to regulate a rotational operation of the operation knob, and to release a rotation-regulated state of the operation knob on condition that the received ID code is determined as a legitimate ID. The main body part, the control unit and the regulation unit are integrally formed to configure an integral unit.
