Abstract: The present disclosure relates to a photodetection device and an electronic apparatus that allow for reducing surface reflection from an on-chip microlens and suppressing deterioration of image quality. Provided is a photodetection device including: a plurality of pixels that have photoelectric conversion units; on-chip microlenses that are formed in such a way as to correspond to the individual pixels; and an antireflection film that is formed on a surface of the on-chip microlens, in which the antireflection film is constituted by a stacking of: a first inorganic film that is formed by a metal oxide film; and a second inorganic film that is formed on a surface of the first inorganic film and has a lower refractive index than the first inorganic film. The present disclosure can be applied to, for example, a CMOS solid-state imaging device.

Abstract: An electronic apparatus includes a touch panel, a vibration generator configured to vibrate the touch pane, a sound generator, and a controller. In response to an operation by the user onto the operation unit, in addition to a control provided to the vibration generator to cause the touch panel to vibrate, the controller performs (i) a control provided to the display screen to change displaying of the operation unit, or (ii) a control provided to the sound generator to generate a sound, or (iv) both the control provided to the vibration generator and the control provided to the sound generator.

Abstract: Methods are disclosed for the production of (I) a cationic water-soluble resin by the reaction of a polyethylene glycol polyhalohydrin ether resulting from the reaction between polyethylene glycol and an epihalohydrin with an aziridine compound and (II) and (III) cationic water-soluble resins by the reaction of (I) the resin with an epihalohydrin and/or a polyfunctional epoxy compound in the presence or absence of a polyalkyleneimine. The resins (I), (II), and (III) are stable over a wide range of pH value and are useful as a water-treating agent.

Abstract: A tape cassette includes a cantilevered reel shaft and an annular reinforcement wall which are integrally molded with a cassette body member in concentric relation to one another. When a reel hub rotatably supported on the reel shaft is subjected to a lateral impact or shock force tending to bend the reel shaft, the reinforcement wall engages an inner bearing wall of the reel hub to limit the deformation of the reel shaft within a elastic limit of the reel shaft.
