    • In the electrodeposited abrasive wheel 20 of the abrasive tool according to the present invention, plural mound parts 21, which are upheaved at the central domain of base metal 19 in almost columnar shape, are arranged mostly in the shape of lattice. An abrasive grain layer 22 is formed on a base metal 19, and plural ultra abrasive grains 14 are adhered only to each mound parts 21 by electrodeposited metal phase 25, and referred as the small abrasive-grain-layer parts 24, respectively. Ultra abrasive grains are laid out at corner R part 21a and top 21b of the mound parts 21 at the small abrasive-grain-layer parts 24. Ultra abrasive grains at each small abrasive-grain-layer parts are set as 11-500 pieces, and the rate which ultra abrasive grains occupy to the whole area of abrasive grain layer accounted by plane projection is set as 20%-80% of the range. At the time of grinding, only ultra abrasive grains contact to grinding work piece, then high abutment pressure is maintained, and sharpness and the discharge performance of ground wastes are good.
    • 在根据本发明的研磨工具的电沉积砂轮20中,在基本金属19的中心区域几乎呈柱形的多个墩部21主要布置为格子形状。 在基体金属19上形成磨粒层22,并且通过电沉积金属相25分别将多个超磨粒14仅粘附到每个堆焊部21上,分别称为小磨粒层部24。 在小的磨粒层部分24处,将超磨粒布置在墩部分21的拐角R部分21a和顶部21b处。每个小磨粒层部分处的超磨粒设定为11-500个, 超磨料占平面投影占磨粒面整体面积的比例为20%-80%。 在研磨时,只有超磨粒与研磨工件接触,保持高的邻接压力,磨碎废物的清晰度和排出性能良好。

    • Drop in the power supply level right after change can be suppressed greatly when changing the power to the internal power supply voltage from the external power supply voltage of an overdrive system. Voltage generating circuit VG0 is connected to the VDL line which raises the VDL line to a voltage higher than VDL beforehand prior to changing to internal power supply voltage VDL from external power supply voltage VDD, and restores the VDL line voltage which drops after the change to VDL. More specifically, there are detecting circuit part 40 which detects the VDL line potential, first switching element M1 connected between the VDL line and the VDD line and which operates according to the detected result of detecting circuit part 40, and second switching element M2 connected between common voltage VSS and connection node ND1 between first switching element M1 and detecting circuit part 40, which changes the potential of connection node ND1 by conducting according to input preliminary voltage step up signal MVDL, and by it conducts first switching element M1 for a fixed time.
    • 在从过驱动系统的外部电源电压改变内部电源电压的电源时,可以大幅度地抑制变更后的电源电平下降。 在从外部电源电压VDD变为内部电源电压VDL之前,将电压生成电路VG0与VDL线连接,将VDL线预先升压至高于VDL的电压,并且将变更后降低的VDL线电压恢复为 VDL。 更具体地,存在检测VDL线电位的检测电路部40,连接在VDL线与VDD线之间的第一开关元件M1,其根据检测电路部40的检测结果进行动作,第二开关元件M2连接在 第一开关元件M1和检测电路部分40之间的公共电压VSS和连接节点ND1,其通过根据输入的初步升压信号MVDL进行导通来改变连接节点ND1的电位,并且通过其将第一开关元件M1导通固定时间 。

    • First heat transfer plates S1 and second heat transfer plates S2 folded along crest folding lines L1 and valley folding lines L2 are bonded to an inner periphery of an outer casing 6 and an outer periphery of an inner casing 7, so that the first and second heat transfer plates S1 and S2 are disposed radiately, thereby forming combustion gas passages and air passages circumferentially alternately. One end of both the combustion gas passages and the air passages is cut into an angle shape, and one side and the other side of the angle shape are closed to form combustion gas passage inlets 11 and air passage outlets 16. In a similar manner, combustion gas passage outlets 12 and air passage inlets 15 are formed at the other end of the combustion gas passages and the air passages. Thus, it is possible to provide a heat exchanger which has a simple structure and is easy to manufacture, and in which the pressure loss due to bending of flow paths can be suppressed to the minimum.
