Abstract: A media processing apparatus includes a slit insertable a sheet bundle of multiple sheets, a sheet-bundle holder, a liquid applier, a press binder, and a controller. The sheet-bundle holder holds the sheet bundle and detects the thickness of the sheet bundle. The liquid applier applies liquid to the sheet bundle. The press binder presses and binds the sheet bundle to perform press-binding process. The controller causes the sheet-bundle holder to hold the sheet bundle and detect the thickness of the sheet bundle, determines whether to cause the liquid applier to apply liquid to the sheet bundle based on the thickness of the sheet bundle, causes the liquid applier to apply the liquid to the sheet bundle when it is determined that the thickness of the sheet bundle is equal or larger than a prescribed thickness, and causes the press binder to press and bind the sheet bundle.

Abstract: An electronic apparatus for a vehicle, includes an electronic device, a waterproof housing that receives the electronic device, and a filter. The housing has a ventilation hole that penetrates through a housing wall of the housing. The filter is attached to a filter attachment portion of the housing wall to cover the ventilation hole. A wall surface of the ventilation hole includes a slope surface section that has an increasing cross-sectional area, which progressively increases from an inner end to an outer end of the slope surface section toward an outer surface of the housing wall in a penetrating direction of the ventilation hole. Furthermore, a distance between the filter attachment portion and the outer surface is larger than that between the inner end of the slope surface section and the outer surface in the penetrating direction.

Abstract: A waterproof case for housing an electronic component includes a case member that has a plurality of breathing holes, and a breathable waterproof filter fitted to the case member at a position corresponding to the breathing holes to cover the breathing holes. For example, open surfaces of at least two of the breathing holes, opened outside of the case member, can be made to face in different directions. Furthermore, the breathing hole has an open area on a side of the breathable waterproof filter, which is larger than an open area of the breathing hole on a side opposite to the breathable waterproof filter, in the case member. Accordingly, the waterproof case enhances waterproofness while circulating air between the inside and the outside of the waterproof case.

Abstract: A small optical transmitter-receiver module capable of regulating the light output level, without changing the mounting position of a laser diode or modifying the laser diode itself, is provided. In the module, a waveguide substrate which forms a planar lightwave circuit, a semiconductor laser element serving as a laser oscillation element which oscillates laser light to be output to the outside transmission path through the planar lightwave circuit, and a photodiode element serving as a light receiving element which receives laser light from the outside transmission path through the planar lightwave circuit, are integrated on a silicon substrate. On an optical waveguide of the planar lightwave circuit, a variable optical attenuator for laser light propagating the optical waveguide is arranged.
