  • Publication number: 20240074573
    Abstract: Brushware contains the constituents of monofilaments or bristles, and at least one head, handle, and/or neck. The constituents contain or are made of polymers from the same polymer class selected from among polymers and/or copolymers, and wherein the polymer class is selected from polyamides or polyesters.

  • Patent number: 10654193
    Abstract: Methods for controlling the surface profiles of wafers sliced from an ingot with a wire saw include measuring an amount of displacement of a sidewall of a frame of the wire saw. The sidewall is connected to a bearing of a wire guide supporting a wire web in the wire saw. Based on the measured amount of displacement of the sidewall, a pressure profile for adjusting a position of the sidewall is determined by a computing device. Pressure is applied to the sidewall using a displacement device according to the determined pressure profile to control the position of the sidewall.

  • Patent number: 10315337
    Abstract: Methods for controlling the surface profiles of wafers sliced from an ingot with a wire saw include measuring an amount of displacement of a sidewall of a frame of the wire saw. The sidewall is connected to a bearing of a wire guide supporting a wire web in the wire saw. The measured amount of displacement of the sidewall is stored as displacement data. Based on the stored data, a pressure profile for adjusting a position of the sidewall is determined by a computing device. Pressure is applied to the sidewall using a displacement device according to the determined pressure profile to control the position of the sidewall.

  • Patent number: 7026831
    Abstract: It is the goal of the invention to provide an improved method and an improved apparatus to measure the diffusion length of minority charge carriers in semiconductors. In particular, the method should be easy to implement. The method should yield higher measurement accuracy. The data analysis should be easy. The apparatus should be easy to use. This goal is achieved using the following procedure steps: Application of periodically alternating light of different wavelengths (?1, ?2) to the semiconductor sample (28); Detection of the surface potential modulation caused by the application of the light, Adjustment of at least one of the light intensities (I1) in such a manner that the surface potential modulation disappears; and Determination of the diffusion length (L) of the minority charge carriers from the adjusted light intensities.
