Abstract: An endpoint detector and performance monitoring system for quickly and accurately measuring the change in thickness of a wafer and other planarizing parameters in chemical-mechanical polishing processes. In one embodiment, an endpoint detector has a reference platform, a measuring face, and a distance measuring device. The reference platform is positioned proximate to the wafer carrier, and the reference platform and measuring device are positioned apart from one another by a known, constant distance. The measuring face is fixedly positioned with respect to the wafer carrier at a location that allows the measuring device to engage the measuring face when the wafer is positioned on the reference platform. Each time the measuring device engages the measuring surface, it measures the displacement of the measuring face with respect to the measuring device. The displacement of the measuring face is proportional to the change in thickness of the wafer between measurements. In another embodiment, a planarizing machine has a flat plate, a planarizing medium fastened to the plate, a carrier assembly to manipulate a substrate holder over the planarizing medium, and a non-contact distance measuring device. The non-contact distance measuring device measures the actual elevation of the substrate holder as the substrate holder engages a substrate with the planarizing medium and relative motion occurs between the substrate holder and the planarizing medium. The performance monitoring system uses the actual pad elevation to determine the endpoint, the polishing rate and other CMP operating parameters.

Abstract: The present invention relates to absorbent devices such as sanitary napkins, pantiliners, interlabial devices, and incontinence devices. In a preferred embodiment, the present invention relates to an improved absorbent device that is insertable into the interlabial space of a female wearer for catamenial purposes (including menses and mid-cycle discharges), incontinence protection (including urine), or both. The absorbent interlabial device has at least one body-contacting surface and a backsheet having an integral protrusion formed therein of sufficient dimensions to aid in insertion into the interlabial space. An apparatus for forming the integral protrusion in the backsheet is disclosed. The apparatus comprises a female forming member having an opening therein, and a compression member having an opening therethrough in operative aligned relationship with the opening of the female forming member. A male forming member having a male forming protrusion operatively disposed in aligned relationship with the openings of the female forming member and compression member, and moveable therethrough can be urged through the openings. A method of making an integral protrusion in a backsheet is disclosed. The backsheet is compressed between the female forming member and the compression member. The backsheet has an uncompressed region coincident the aligned openings of the female forming member and the compression member. A male forming protrusion is urged through the aligned openings, thereby contacting and straining the backsheet material coincident said first and second openings to form a strain induced plastically deformed protrusion in the backsheet.

Abstract: The 4 mA-20 mA type or 0-20 mA type current loop connects an analog sensor (1) to an acquisition system (3), respectively carrying a sensor current (Ic) and an acquisition current (Ia). A test circuit is connected in parallel with the current loop to inject a superposition current (Is) into said loop, which current is superposed on the sensor current (Ic) or on the acquisition current (Ia). In a first embodiment, a variable voltage generator (7) injects the superposition current (Is) by adding it to the acquisition current (Ia), thereby making it possible to check a low-current threshold of the acquisition system (3). In a second embodiment, a variable current regulator injects the superposition current (Is) by adding it to the sensor current (Ic), thereby making it possible to check a high-current threshold of the acquisition system. The high- and low-current thresholds of the acquisition system are tested without opening the current loop.

Abstract: Oppfinnelsen omhandler utforming av et vedlikeholdsvennlig hydraulikksystem ved produksjon av energi fra bølger. Figur I viser et hydraulikksystem som innsamler bølgeenergi. Hydraulikksystemet er lokalisert på sjøbunnen og festet til et flytelegeme på overflaten. Hydraulikksystemet består av en sylinder med et indre bevegelig stempel. Fra hydraulikksystemet går et rør- eller en slangeforbindelse til en annen enhet hvor et ventilsystem er lokalisert, vanligvis nær enheten for utnyttelse av energien i væsken med forhøyet trykk fra hydraulikkenheten. Ventilsystemet er nødvendig for at hydraulikksystemet skal kunne levere væske med forhøyet trykk. Ventiler er innretninger som krever ettersyn og vedlikehold over tid. Oppfinnelse gjør dette mulig ved at ventiler som er nødvendig for at den hydrauliske innretningen skal kunne levere væske med et forhøyet trykk er lokalisert på en enhet uavhengig av og på betydelig avstand fra den hydrauliske innretningen. Denne enheten kan utformes slik at den er lett tilgjengelig for vedlikehold og inspeksjon.
