A battery pack includes a plurality of lithium battery cells, an analog thermo sensing member, and an analog switch. The analog thermo sensing member detects, in an analog form, a battery temperature of at least one of the plurality of lithium battery cells, and outputs an output preventing signal if the battery temperature is over a first predetermined temperature. The analog switch element is the plurality of lithium battery cells in series, and is switched, based on the output preventing signal, to a state in which a current is prevented from flowing in the plurality of lithium battery cells.

An electric device mounting type tool storage case that is easily transported together with other electric devices such as audio devices in addition to an electric tool body and can stand against contamination such as dust in the work site. An audio device as an electric device can be stored in the tool storage case which is used as an enclosure of a pair of speakers. Storage portions disposed in the tool storage case are partitioned by partition walls into a pair of sound channel spaces. In addition, a power switching circuit of an AC-DC converter power supply circuit or a battery DC power supply is formed in the tool storage case, and power wiring lines or inner wiring lines are disposed along the partition walls. While a cover case closes a storage case, electric devices such as an audio device or a charger are operated.

A sliding surface of a high-temperature portion is subjected to an electro-discharge surface treatment with one or both of a high-temperature hard material (4) and a material having a lubricating property at a high temperature (6). The high-temperature hard material (4) is any or a mixture of cBN, TiC, TiN, TiAlN, TiB2, WC, Cr3C2, SiC, ZrC, VC, B4C, Si3N4, ZrO2, and Al2O3. The material having the lubricating property at the high temperature (6) contains chromium and/or chromium oxide (Cr2O3) and/or hexaboron nitride (hBN). An electrode formed by compression molding of the high-temperature-hard material, and the high-temperature lubricating material containing at least one of Cr and hBN and having the lubricating property at the high temperature is used as the electrode for the electro-discharge surface treatment.

摘要:
A battery charger includes a battery voltage detector for detecting the voltage of a secondary battery and a battery temperature sensor for detecting the temperature of the secondary battery. A controller determines the voltage of the secondary battery prior to beginning the charging process based on output from the battery voltage detector. The controller also determines the charging level from among a plurality of levels that indicate how much time is required for the secondary battery to reach a full charge, based on the determined voltage of the secondary battery and output from the battery temperature sensor. A display is provided for displaying the charging level that indicates the time remaining to achieve a full charge.

A DC power source unit supplies a DC voltage to an electrically powered tool through an adapter and also charges a battery pack used as an alternative power source of the tool. With the DC power source unit of the invention, a microcomputer receives a temperature signal indicative of a temperature of the battery pack and determines that the battery pack is fully charged based on the temperature signal. This determination is made regardless of whether the battery pack is being charged or not. As such, the fully charged condition of the battery pack can be accurately detected even if the tool is operated when the battery pack is almost fully charged.
摘要:
A stretchable warp knitted fabric comprising warp knitting yarns, first weft in-laid yarns and second weft in-laid yarns, and stretchable warp in-laid yarns. The second weft in-laid yarns consist of a plurality of at least non-stretchable yarns, and said second weft in-laid yarns run sequentially and separately in the course direction on different wale regions of the same course with having an arbitrary length respectively, while crossing the first weft in-laid yarns between courses. Consequently, even when pulled in a longitudinal direction, because the separate second weft in-laid yarns influence each other independently, the fabric does not have a great amount of ruffling in a width direction thereof and thus the a flat surface is maintained wherein there is no narrowing in the middle of the longitudinal direction.
摘要:
A knitted surface fastener wherein pile loops are formed by knitting-in pile knitting yarns at the same time when a foundation fabric is knitted with foundation yarns. After the pile knitting yarns which form the pile loops stride between two or more wales to form loops, they are entangled with each stitch of the foundation yarns of three or more adjoining courses on a same wales continuously to form stitches. Of the stitches of the pile knitting yarns formed due to the pile knitting yarns entangled per each of the adjoining three or more courses, at least one or more stitches located in the middle are formed in a closed loop. Consequently, the necessity of back coating is eliminated and further, clearly square gaps are formed to achieve ventilation property and transparency.
