  • Publication number: 20100117580
    Abstract: In a rechargeable electric power tool, upon changeover of a trigger switch, a microcomputer determines the magnitude relation between the detected temperature outputted from the first thermistor and the first temperature threshold value, the second temperature threshold value and the third temperature threshold value, and the magnitude relation between the first calculated temperature increase rate and the first preset temperature increase rate. If the detected temperature is determined to be greater than the first temperature threshold value or if the first calculated temperature increase rate is determined to be greater than the first preset temperature increase rate after the detected temperature has been determined to be greater than the second temperature threshold value, the microcomputer is set in a limited operation mode in which the revolution number of the motor is limited to a predetermined value or less.

  • Publication number: 20090263974
    Abstract: A substrate processing system which sprays exposure process gas onto a substrate disposed within a chamber. The substrate processing system is used, for example, for performing an exposure process of an organic film formed on a substrate in a gas atmosphere obtained by vaporizing an organic solvent solution for dissolving and reflowing an organic film. The substrate processing system comprises: the chamber having at least one gas inlet and at least one gas outlets; a gas introducing means which introduces the exposure process gas into the chamber via the gas inlet; and a gas distributing means. The gas distributing means separates an inner space of the chamber into a first space into which the exposure process gas is introduced via the gas inlet and a second space in which the substrate is disposed.

  • Publication number: 20080281452
    Abstract: To efficiently construct a three-dimensional model. A product is divided into two parts of a head portion and a neck portion. A head form 34 and a neck form 36 are selected as forms of a three-dimensional model. The basic dimensions of each part are inputted to calculate dimension values of each part, and a combination of a basic form and a cut part is selected in accordance with a table 38. If it is necessary to change the basic form of the neck form 36, the dimensions of a basic-form model 40 are changed to construct a model 42. Furthermore, a cut part 48 is selected, and the model 42 is processed to construct a model 50. Then, by combining a head-form model 52 and the neck-form model 50, a three-dimensional model 54 of a bolt is constructed.

  • Publication number: 20080122400
    Abstract: A battery charger includes an attachment portion capable of being connected to a plurality of battery packs; a connection unit for connecting one of the battery packs connected to the attachment portion to a charging path; a state detection unit for detecting a state of each of the battery packs; a remaining capacity detection unit; and a charging control unit. The remaining capacity detection unit detects a remaining capacity based on the state of the battery pack detected by the state detection unit after each of the battery pack is charged for a specified period of time. Further, the charging control unit assigns priorities to the battery packs such that one whose remaining capacity detected by the remaining capacity detection unit is closer to a fully charged state thereof has a higher priority, and controls the connection unit to charge the battery packs according to the assigned priorities.

  • Publication number: 20070146362
    Abstract: An automatic drawing creation system in which dimension lines required for a two-dimensional drawing are automatically written when the two-dimensional drawing is created from a three-dimensional model. A product specification determination means 10 creates a three-dimensional model which is then held while being associated with its attribute values. After a specified drawing frame is extracted from a drawing frame database 18 by an automatic drawing creation means 22, a two-dimensional projection drawing is created on the extracted drawing frame by projecting the three-dimensional model.

  • Patent number: 7208915
    Abstract: A constant-current battery charger includes a power supply for supplying a charge current to a secondary cell, and a current monitor for monitoring a charge current being supplied to the cell. A controller is included for varying the charge current in accordance with the monitored charge current. The controller calculates a current difference between a predetermined target current and the instant charge current, and generates a demand of varying the charge current at a first charge rate when the current difference is out of a predetermined range, and varying the charge current at a second charge rate when the current difference is within the predetermined range. The controller generates the demand repeatedly at regular or varying intervals for varying the charge current. The first charge rate is set to be higher than the second charge rate in order to make a rapid charging until it comes close to the target current.
