Abstract: In a process for manufacturing formwork for pillars, a tube is formed from a multiplicity of tapes originating from an initial reel. This consists of a laminated composite of polyethylene film, cardboard, aluminium and polyethylene film and passes in tape form through a tunnel with a temperature of less than 100 DEG C, in order to bring the polyethylene films into the molten state. By this means, the tapes can be intimately welded together when running onto a rotating mandrel. The tapes rest during this with approximately 50% of their width on the respective leading tape and because of their welding are subject to tension and compression. The tube thus formed on the mandrel is cut off from this in suitable lengths. <IMAGE>

Abstract: An optical pickup device capable of maintaining a sufficient amount of laser beam light when recording information on an optical disc and stabilizing the light emission of the semiconductor laser when reproducing information. Each optical component constituting an optical system for an optical pickup device used for both information recording and reproducing is formed with an antireflection film whose spectral reflectance changes in accordance with the wavelength of an incident light. 
     And, in a preferable embodiment, the antireflection film, which has a high spectral reflectance at a shorter wavelength λ (L) in the whole range of light emission wavelengths covered by the semiconductor laser light source and a low spectral reflectance at a longer wavelength λ (H), is formed on the incident surface or outgoing surface of at least one optical transparent element (for example, 5). 
     As a result, in recording information on an optical disc wherein a laser beam is emitted at a high output power and at a wavelength λ shifted to a longer peak wavelength λ (H), the transmission coefficient of a laser beam becomes high. Furthermore, in reproducing information wherein a laser beam is emitted at a low output power and at a wavelength λ shifted to a shorter peak wavelength λ (L), the transmission coefficient of a laser beam becomes low, reducing the amount of light returned to the emission surface of the semiconductor laser.

Abstract: Vibration sensors are used to monitor the resonant frequency of each cylinder of a multi-cylinder engine and the detection of an abnormal resonant frequency, i.e., one outside of an established range, is used as an indication that one or more specific cylinders is operating at an improper power level. Vibration signals associated with combustion in each cylinder can be used to perform FFT (Fast Fourier Transformation) with the combustion resonant frequencies for all engine cycles being determined and an averaged resonant frequency for each cylinder obtained. Shifts in the averaged resonant frequency or the detection of a zero resonant frequency for only one of the cylinders can be used as an indication that the cylinder with the shifted or zero resonant frequency is experiencing a low power condition, including misfiring.
