Title: Powder for magnetic core and production method thereof, dust core and magnetic film
Inventor: YATSUGI KENICHI
IPC: H01F1/147
Filed: 2017-03-08
Abstract: PROBLEM TO BE SOLVED: To provide powder for magnetic core composed of soft magnetic particles of nano size where ferrite is produced uniformly on the surface.SOLUTION: Powder for magnetic core is composed of particles for magnetic core including soft magnetic particles composed of Fe and Ni and having granularity of 5-400 nm, magnetite on the surface thereof, and spinel-type ferrite on the surface of the soft magnetic particles having magnetite. Such a soft magnetic is obtained by performing ferrite plating of the oxide particles, where magnetite is generated on the surface of the soft magnetic particles, in an alkaline aqueous solution. Since the isoelectric point of magnetite exists on the weak acidic side, the oxide particles in the alkaline aqueous solution are in a state charged with negative charges, adsorbs cations becoming the raw material of ferrite strongly, and are not aggregated but dispersed. Powder for magnetic core composed of soft magnetic particles of nano size, where uniform ferrite coating is formed, is thus obtained.SELECTED DRAWING: Figure 2A

Title: Sanitary washing device
Inventor: SHIMOYAMA TAKEHIRO
IPC: E03D9/08
Filed: 2017-03-14
Abstract: PROBLEM TO BE SOLVED: To determine quickly whether a nozzle is clogged or not when a nozzle ejecting washing water is changed and to inhibit a tube from being detached due to clogging occurring in a nozzle without increasing the number of components.SOLUTION: When a state in which washing water is ejected from any nozzle of a plurality of nozzles by driving an electric switch valve is switched to a state in which washing water is ejected from another nozzle, it is determined that the other nozzle is clogged in a case where a rotational period of a rotary blade in a flow sensor reaches a predetermined or higher period within a predetermined time after the start of switching. Thus, because it can be determined whether the nozzle is clogged or not before a stop of the rotary blade, a water cutoff solenoid valve can be closed before a tube is detached.SELECTED DRAWING: Figure 3

Title: Blower device
Inventor: HINO YUKO
IPC: F04D17/10
Filed: 2017-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a centrifugal blower device mounted on electronic equipment and the like which is thin and light-weight and which has good air blowing efficiency.SOLUTION: A blower device includes: a blower part 40 having a plurality of flat plates 410 arrayed via a gap 400 in an axial direction; a motor part 30 for rotating the blower part; and a housing for accommodating the blower part and the motor part. The housing includes: an intake port 202 penetrating in the axial direction at an upper part of the blower part; and an air blowing port opening toward the radial direction radially outside of the blower part. At least one part of the flat plates has a plurality of through-holes penetrating in the axial direction. When the blower part rotates, by viscosity resistance of the surface of the flat plate and a centrifugal force, an airflow going radially outside generates between the flat plates. As the airflow generates between the flat plates, the airflow hardly leaks in the vertical direction, and air blowing efficiency can be improved. Therefore, even in the case where the thickness is reduced, air blowing efficiency hardly deteriorates. Also, by the flat plate having the through-holes, the weight of the blower device can be reduced.SELECTED DRAWING: Figure 5
