Title: Air cleaner
Inventor: FUKUDA MITSUO
IPC: B03C3/14
Filed: 1989-04-07
Abstract: PURPOSE:To reduce the generation of ozone and to give a person no uncomfortable feeling by increasing the surface electric charge density of an electrically charged filter and making the discharge current between a discharge wire and an electrode plate to be the minimum current value at which the dust collecting efficiency is saturated. CONSTITUTION:The dust particles contained in the room air sucked from a suction opening 2 by the revolution of a blower 4 are electrically charged and collected by an electrically charged filter 11. The amount of ozone generated by corona discharge made between a discharge wire 5 and an electrode plate 6 is increased as the discharge current I between the discharge wire 5 and the electrode plate 6 is increased. The dust collecting efficiency of dust collecting filter is varied according to the discharge current I and the surface electric charge density of the electrically charged filter 11. As the filter of large surface electric charge density corresponding to the electrically charged filter A is used for the electrically charged filter 11, sufficiently high dust collecting efficiency is obtained even with low discharge current I1, and the amount of ozone generated is small and the odor is also reduced because of small discharge current I.

Title: Vertical insulated-gate type field effect transistor
Inventor: YAZAWA YOSHIAKI
IPC: H01L29/08
Filed: 1987-04-13
Abstract: PURPOSE:To reduce a space between wells without increasing the ON resistance of a vertical double-diffusion MOSFET (VDMOS) and decrease the product (Rons) of the area of an element and the ON resistance, by forming a groove in a semiconductor substrate between neighboring base body regions, and making the concentration of first conductivity type impurities around said groove in the semiconductor substrate higher than that in a drift region. CONSTITUTION:A groove 20 is formed in a region held between wells 13. The concentration of impurities around the groove is made high, and the resistance at this part is decreased. Namely, the impurities, whose concentration is higher than that in another drift region 11, is introduced in a contact part of the groove 20 and the drift region 11. Therefore, even if a depletion layer is expanded toward the drift region 11 from the boundary part between the wells and the drift region, a high concentration impurity layer 21 around the groove is not depleted, and a low resistance state can be kept. Thus the Rons of a VDMOS can be decreased without impairing the breakdown strength of an element and without requiring especially high machining accuracy.
