Abstract: In an apparatus for determining characteristics of materials by photoreflectance the sample (62) is irradiated by light from a monochromatic light source (50, 51) and a pump beam source (63). The reflected ligth is analyzed by a detector (56), a lock-in amplifier (55), a A/D converter (66) and a computer (70). The d.c. signal of the detector (56) is kept constant for a certain measurement by means of a variable neutral density filter (58) in the monochromatic light beam. By varying the pump beam wavelength and its modulation fre­quency by the use of an acousto-optical modulator the compo­nent layers, their quality and the properties of the various interfaces in the sample (62) are determined.

Abstract: In an optical fiber ribbon fusion-splicing device, a TV camera (16) is set such that the horizontal direc­tion (H-direction) of an image sensor (17) contained in the TV camera in which direction a horizontal scanning is carried out and the resolution of the image sensor is higher than that in the vertical direction (V-direction) in which a vertical scanning is carried out is a direc­tion (Y-direction) perpendicular to the coaxial direction (X-direction) of a pair of grooved supporting members (11₁, 11₂) for supporting fibers (12₁, 12₂) of a pair of optical fiber ribbons (10₁, 10₂) to be fusion-spliced. Thus, when the fibers of the pair of optical fiber ribbons are set on the supporting members in the coaxial direction thereof, the horizontal direction of the image sensor is perpendicular to the coaxial direction of the fibers of the optical fiber ribbon. Since, therefore, misalignment of the fibers is involved in the high resolution direction, the misalignment can be detected with high precision, without decreasing the power factor of the image sensor.

Abstract: An edge sealer (12) includes a heater anvil (16) having a heater band (22) disposed in a convex configuration and lying opposite a drive belt (34). Multi-ply business forms are conveyed along the edge sealer (12), with the edge of the form extending between the belt (34) and the heater band (22). Application of heat by the heater band (22) to the edge activates the heat-sensitive adhesive to adhesively seal the edges of the plies one to the other without applying heat to the body of the form. A conveyor system transfers forms from one conveyor (60) to another (62) without change of spatial orientation of the forms to pass the unsealed edges of the forms through an additional edge sealing unit (12) downstream of the first edge sealing unit (12).

Abstract: The control of a multiphase brushless DC motor in a star-­configuration without using position sensors for the perma­nent magnet rotor is carried out by detecting signals having a substantially sinusoidal waverform, which are representa­tive of the difference in voltage between ends of the phase windings and the star-center, selecting the signal relating to a non-excited phase winding, detecting the crossing by the selected signal of a reference voltage level, generating a logic commutation signal upon the crossing by the selected signal of said reference voltage level, and commutating the excitation of the motor by means of said logic commutation signal thus generated and simultaneously masking said repre­sentative signals so as to prevent their selection for a time which is sufficiently long to allow the decay of the spikes caused by the last commutation before restarting the cycle. The analysis of the voltage signal of the non-excited phase winding, carried out in the "sinusoidal" section close to the axis of absissas, makes it possible to obtain information on the emf induced by the movement of the permanent rotor on the phase windings of the stator essentially free of terms linked to the inductance and resistance of the windings themselves as well as without the occurrence of spikes due to the previous commutation. Preferably, the masking of the signals takes place by means of a logic masking signal which has a duration equal to a preset fraction of the period of time intervening between the two last successive commutations of the motor, which changes in an essentially gradual manner. The functional diagrams of the various circuit blocks according to a preferred embodiment are illustrated.

Abstract: A filter element made from a filter web material pleated in zig-zag fashion is to be sealed at the end edges. In particular, the sealing is to be achieved via an applied end disc. The sealing is to be carried out via a plasticisable material, the plasticisable material being able to be joined to the filter web material or the sealing material which it can itself be in each case.   The plasticising to produce the seal should be carried out in the most energy-saving manner possible and in a locally restricted manner. For this purpose, the filter web material and the sealing material are joined together via the plasticisable material present by means of high-frequency welding (ultrasound).
