A gate driver turns on/off a switching element Q1 by applying a control signal from a controller to a gate of the switching element. The switching element has the gate, a drain, and a source and contains a wide-bandgap semiconductor. The gate driver includes a parallel circuit that includes a first capacitor C1 and a first resistor R1 and is connected between the controller and the gate of the switching element and a short-circuit unit S4 that is connected between the gate and source of the switching element and short-circuits the gate and source of the switching element after a delay from an OFF pulse of the control signal.

Techniques are disclosed herein for applying different process steps to single-level cell (SLC) blocks in a memory array than to multi-level cell (MLC) blocks such that the SLC blocks will have high endurance and the MLC blocks will have high reliability. In some aspects, different doping is used in the MLC blocks than the SLC blocks. In some aspects, different isolation is used in the MLC blocks than the SLC blocks. Techniques are disclosed that apply different read parameters depending on how many times a block has been programmed/erased. Therefore, blocks that have been cycled many times are read using different parameters than blocks that have been cycled fewer times.

In a switchgear, oscillation of a moving current-carrying shaft and a moving contact of a vacuum valve is minimized, offset load on the contact surface is reduced, and friction the portion supporting the moving current-carrying shaft is reduced. A vacuum valve is disposed in a gas tank, one end of a moving current-carrying shaft integrally includes a moving contact of the vacuum valve, and a contact pressure adjusting spring is disposed on the other end of the moving current-carrying shaft. An operating rod extends through the gas tank, an operation mechanism is mounted on the operating rod outside the gas tank, an insulating rod is mounted inside the gas tank, and the contact pressure adjusting spring is joined to the insulating rod.

A method for correcting a proximity effect applied to a dose of an electron beam exposure, includes classifying an underlying pattern of a level underlying a thin film layer; dividing a processing pattern to be transferred on the thin film layer into a first pattern overlapping with the underlying pattern and a second pattern which does not overlap with the underlying pattern according to the classified underlying pattern; calculating a pattern area density for the first and second patterns in a unit region; and calculating a corrected dose for the processing pattern according to the pattern area density.

Disclosed is a toner residual quantity detecting apparatus for detecting a residual quantity of toners in a developing unit. This toner residual quantity detecting apparatus has a temperature sensor, provided in the bottom of the developing unit, for generating an output proportional to a detected temperature and a detecting circuit for detecting the toner residual quantity from the output of the temperature sensor. This temperature sensor detects a difference between temperatures when covered with the toners and when not covered with the toners, thereby detecting the toner residual quantity.
