An electric motor used for example in a magnetic disk drive, comprises a rotor having a hub on which the magnetic disk is mounted, and an annular driving permanent magnet, and rotating together with a rotary shaft, and a stator disposed outside the rotor, having a core and coils wound on the core. A signaling permanent magnet for detecting the rotary angle or the rotational speed of the rotor may be provided on the radially inner side of the driving permanent magnet. Part of the outer periphery of the stator core may be retracted radially inward or cut away to form a concavity or an open part. A magnetic shielding plate may further be provided to cover the coils, with part or the entirety of the magnetic shielding plate being positioned closer to the rotary shaft than the outermost periphery of the rotor to prevent the escape of the rotor in the direction of the rotary shaft. The stator core may be provided, at its inner extremities, bent portions extending in the direction parallel with the rotary shaft, and away from the hub. Alternatively, the midpoint of the stator core may be positioned farther away from the hub than the midpoint of the driving permanent magnet.

An electrical connector contains a plurality of contacts, a first ground plate and a second ground plate facing the plurality of contacts and arranged so as to be separated from each other in a ground plane parallel to the at least one plane in which the plurality of contacts are arranged and an insulator for holding the plurality of contacts, the first ground plate and the second ground plate in a state that the plurality of contacts, the first ground plate and the second ground plate are insulated from each other. Both of the first ground plate and the second ground plate include an extending portion extending from one of the first ground plate and the second ground plate toward the other one of the first ground plate and the second ground plate in the ground plane.

An electrode formation method for a solar cell to form an electrode of a base member, includes a screen printing process and a baking process. The screen printing process includes: mounting a metal mask on a surface of the base member, wherein the metal mask includes a covering portion configured to cover a part of a surface of the base member, opening portions configured to allow parts of the base member to be exposed therefrom, and bridge portions disposed along a direction intersecting with a longitudinal direction of circuit patterns between the opening portions; and supplying a paste to an upper surface of the metal mask by a squeegee head of a cartridge type, while relatively sliding a squeegee on the upper surface of the metal mask such that the squeegee travels relatively to the metal mask. In the baking process, the paste is baked to form the electrode.

An analog unit having a multiple-channel configuration among analog units included in a sequencer system is such that an AC signal as a measurement target, which is captured by a CT sensor, can be directly input to each of a plurality of channels, and the analog unit includes a setting unit that sets, in an internal memory, an abnormality-determination peak current value and an abnormal peak current duration, which are applied to the AC signal as a measurement target, for each of the channels, and a detecting unit that, when the AC signal as a measurement target includes an AC signal that maintains a state where a peak value exceeds the abnormality-determination peak current value for the abnormal peak current duration, detects generation of an abnormal alternating current in each of the channels.

To provide a screen printing apparatus and a screen printing method which can enhance a plate separating property after a printing operation regardless of a type of a mask, thereby suppressing occurrence of printing failure. A screen printing apparatus includes mask supporting means 6 for supporting a mask 2 from the rear surface thereof, holding means 20 for holding a printing medium 3, posture changing means 30 for changing a posture of the printing medium 3 held by the holding means 20 between a parallel posture parallel to the mask 2 and a tilted posture tilted about the mask 2, and lifting means for lifting the holding means 20 so as to contact and separate the surface of the printing medium 3 with or from the rear surface of the mask 2. Here, the printing medium 3 having been subjected to a pattern printing operation is separated from the mask 2 from one end of the printing medium to the other end thereof. Accordingly, it is possible to enhance a separating property between the printing medium 3 and the mask 2, thereby suppressing occurrence of printing failure.

An automatic urine collecting device (1) is provided with: a main tank (20) for collecting and containing urine received by a urine receiver; a body case for supporting the main tank (20); a suction pump (53) for sucking the urine, which is received by the urine receiver, into the main tank (20) through a urine flow path by sucking air within the main tank through an airflow path; a urine sensor for detecting urine; and a control device for outputting a control command on the basis of the result of the detection by the urine sensor. The urine sensor is provided with a main-tank infrared sensor (S31) capable of detecting bubbles present in the upper part of the urine contained in the main tank (20). The configuration enhances the reliability of the suction pump.

There is intended provision of a screen print mask cleaning unit that enables efficient wiping of paste from a screen print mask conforming to a cavity substrate, a screen printing machine, and a screen print mask cleaning method. A rubbing area 34a of a paper member 34 is rubbed against an undersurface of a mask region for a flat area (MRF), thereby wiping out paste PT adhering to the undersurface of the MRF. The rubbing area 34a of the paper member 34 is sequentially rubbed against undersurfaces of respective protruding portions 3a in a mask area for cavities (MRC), thereby wiping out the paste PT adhering to the undersurfaces of the respective protruding portions 3a. In the course of wiping of the paste PT adhering to the undersurfaces of the respective protruding portions 3a, the paper member 34 is taken up in a period from when the rubbing area 34a of the paper member 34 is separated apart from one protruding portion 3a until when the rubbing area 34a contacts another protruding portion 3a, thereby updating the rubbing area 34a of the paper member 34.
