The access port in the molding compound opens through into the through hole of the semiconductor component and, together with this and the hollow space between the further semiconductor component and the membrane structure, forms the access channel to the membrane structure.

The invention relates to a wiper device (10) for cleaning a vehicle windscreen, with a wiper blade (15), which is fastened exchangeably on a wiper arm (11), wherein along the wiper blade (15) an elongatedly constructed spray device (40) having several nozzle openings (50) is arranged for applying a washing fluid to the vehicle windscreen, which is constructed as a separate component from the wiper blade (15). It is provided according to the invention that the wiper arm (11) has a hood-shaped cover (20) for the wiper blade (15), which covers the wiper blade (15) over its entire length, and that the spray device (40) is arranged in the area of the cover (20).

Provided are an overcurrent protection device and an overcurrent protection system which can provide time differences among the timings for executing the retry operations among a plurality of overcurrent protection devices connected to a common power supply. When a battery voltage (VBA) becomes a value equal to or lower than a threshold voltage after an FET (Q1) of an IC circuit (51-1) is turned on, all FETs (Q1) of the respective IC circuits are turned off, and a time until the battery voltage (VBA) reduces to a value lower than a threshold voltage after the turning-on of the FET (Q1) is clocked. When the time is smaller than 400 [mu]sec, the count value N is incremented. Further, turning-on of the FETs (Q1) is repeated after the lapse of the standby time (Tp) set randomly. When the count value N reaches 7, the FET (Q1) of the IC circuit (51-1) is held in the turned-off state. Accordingly, only the load-driving circuit at which the dead short occurs can be stopped and the driving of the other load-driving circuits can be continued.

A film roll comprising a heat-shrinkable polystyrene based resin film wound into a roll, characterized in that, each of the samples taken out from the roll exhibits, in a heat shrinkage test under the condition of the immersion in a hot water at 85 DEG C. for 10 sec, a heat shrinkage rate in the main shrinking direction of within +-5% relative to an average rate of the total samples; a heat-shrinkable polystyrene based resin film taken from the roll; a heat-shrinkable label comprising the film; a method for producing the heat-shrinkable polystyrene based resin film roll which comprises using raw material chips having a specific form, or using a hopper having a specific shape for feeding raw material chips to an extruder, or limiting the variation of the surface temperature of a film in a specific production step to a specific range.
