    摘要: A lubricant supply device is to be fitted to a nut member engaging with a screw shaft through rolling members to supply lubricant to the screw shaft along with a relative rotational motion of the nut member to the screw shaft. The device comprises an application member, a lubricant storage member and a control device. The application member for applying the lubricant on the screw shaft has at least one tongue portion, which is capable of coming into contact with at least one of rolling-member running surface of the screw shaft. The number of the at least one tongue portion is identical with or larger than the number of the rolling-member running surface. The lubricant storage member supplies the lubricant to the application member. The control device controls an amount of the lubricant supplied from the lubricant storage member to the application member.

    摘要: A nonvolatile semiconductor memory for setting control voltages to be supplied to an internal circuit, to an external reference voltage inputted from outside, has a parameter control circuit. The parameter control circuit causes a parameter register to sequentially output the plurality of parameters to a voltage generating control circuit. The parameter control circuit counts, for a fixed period of time, the number of oscillations of each of the trimming flag signals sequentially outputted from the voltage generating control circuit in response to the parameters. The parameter control circuit stores counted values corresponding to the parameters. The parameter control circuit selects the parameter having a maximum counted value as a parameter corresponding to the control voltage closest to the external reference voltage.

    摘要: In a memory cell array, memory cells enabled to store plural-bit data are arranged in matrix. The bit-line control circuit is connected to bit-lines to control the bit-lines. A word line control circuit applies a plural-bit data read voltage as a word line voltage to the word line. The plural-bit data read voltage is larger than an upper limit of one of plural threshold voltage distributions and smaller than a lower limit of another threshold voltage distribution. Furthermore, it applies a soft-value read voltage as a word line voltage to the word line. The soft-value read voltage is smaller than an upper limit of a threshold voltage distribution and larger than a lower limit thereof. The likelihood calculation circuit calculates likelihood of the plural-bit data stores in the memory cells based on the soft-value.
