Abstract: To prevent drawing by pen input from stopping due to a failure in receiving an uplink signal, an active pen according to the present disclosure includes a processing circuit that transmits, at a second timing decided based on a first timing of a first uplink signal received from a sensor controller, a position signal and a data signal from a pen-tip electrode and receives a second uplink signal, and a wireless communication circuit that wirelessly communicates with the sensor controller. The processing circuit determines whether the second uplink signal has been received at the second timing, and in a case of determining that the second uplink signal has not been received, the processing circuit transmits at least part of the data signal via the wireless communication circuit while transmitting the position signal from the pen-tip electrode.

Abstract: The case side wall and the upper cover 24 are sealingly connected at the upper wall. The case side wall and the lower cover are sealingly connected by an inner flange. A first member of one steel plate of the case side wall forms a portion of the upper wall that is sealingly coupled to the upper cover, an inner flange, and an inner wall in one piece seamlessly and without holes. The inner wall serves as a waterproof wall, and even if water enters the tubular portion of the case side wall, it is possible to prevent water from entering into the battery accommodating space of the battery case.

Abstract: The case side wall of the battery case has a tubular portion with a closed cross-section structure consisting of an upper wall, a lower wall, an inner wall, and an outer wall, an inner flange, and an outer flange. A first member made of a steel plate forms an inner flange, an inner wall, an upper wall, an outer wall upper portion, and an outer flange, and a second member made of a steel plate forms an outer flange, an outer wall lower portion, a lower wall, and two reinforcing walls. The reinforcing wall is located in the interior space of the tubular portion at the same height as and below the outer flange. A reinforcing wall is placed at a position facing the shock absorber, increasing the strength of this part, suppressing deformation of the case side wall in a side collision, and suppressing damage to the battery case.

Abstract: A film formation device (10) that increases the mechanical resistance of the liquid repellent film formed on the oxide film. The film formation device (10) includes an oxide film formation unit (14, 15, 16), which forms an oxidized film on a substrate by releasing grains towards the substrate that is rotated in a vacuum chamber (11), and forms an oxide film on the substrate by emitting oxygen plasma towards the oxidized film. A vapor deposition unit (17) vapor-deposits a silane coupling agent, which contains a hydrolytic polycondensation group and a liquid repellent group, on the oxide film. A polycondensation unit (20) polycondenses the silane coupling agent by supplying water towards the oxide film on the rotated substrate. The polycondensation unit supplies water to the oxide film before the vapor deposition unit vapor deposits the silane coupling agent on the oxide film.
