Patent DE-3937554-A1 (DE)
Inventor: STING DONALD W
IPC: G01N21/55
Filed: 1989-11-10
Abstract: A fluid monitor includes an MIR crystal 20 mounted in and sealed to a fluid chamber 1 to place a monitoring section of a first surface 21 thereof in contact with the fluid. A backup member 27 bearing against a second surface 22 of the MIR crystal cooperates in securing the MIR crystal to the fluid chamber, the backup member being longer than the monitoring section but shorter than the MIR crystal itself, thereby to reinforce the monitoring section of the MIR crystal against the elevated pressures and temperatures of the fluid while cooperatively defining a radiant energy inlet area 33 at one end of the MIR crystal and a radiant energy outlet area 34 at the other opposite end. Radiant energy successively reflects along the first and second surfaces of the crystal, with the fluid selectively absorbing certain frequencies along the monitoring section, and exits to a detector 47 to monitor and identify the fluid by determining the energy frequencies or bands absorbed by the fluid. <IMAGE>

Title: Laser-induced CVD process - using frequency tuned, grazing incidence laser beam, esp. for refractory metal deposition
Inventor: GAERTNER GEORG DR
IPC: C23C16/48
Filed: 1990-04-10
Abstract: In laser-induced photolytic reactive deposition from the gas phase (LICVD), laser beam absorption occurs in a boundary layer in the near-surface gas space and an adsorption edge layer on a substrate surface by (a) laser beam radiation into the layers at a frequency timed to at least one vibrational transition of the molecules to be dissociated in the layers; (b) flat grazing incidence of the laser beam(s) at 80-89.9 deg. angle of incidence onto a substrate which in smooth relative to the incident laser light wavelength; and (c) use of a pulsed laser beam of pulse width which is less than the time constants for the vibration-translation-relaxation or which is of the same order of magnitude as the time constants. USE/ADVANTAGE - The process is esp. useful for LICVD of refractory metals (e.g. IV) from metal halide/hyrogen gas mixts.. It employs much lower energy densities than the process of DE4003882 and gives a wavelength-dependent increase in W/deposition rate of up to 2.5 times the thermal background rate (i.e. without the laser radiation).

Title: Automatically adjustable vee block for cylindrical work - has rigid cross rack drive connecting two halves of block and maintaining centre
IPC: B25B11/00
Filed: 1991-01-12
Abstract: Two plates (2, 3) slide side-by-side in a tee-slot in the base (1). Viewed in the direction of the work axis the plates form a 90 deg. vee opening with a vertical step (5) part way down the slope. A square sliding block (7) can move along 45 deg. crossed slots in the two plates. Mounted in the blocks is a shaft (13) with pinions (11, 12) which engage with racks (9, 10) securely fastened to the plates along the sides of the crossed slots. Fastened to the sliding block is a bridge piece (8) forming a guide for a bar (14) which is lightly spring loaded towards the workpiece. A pin (15) is secured to the bar so that when the bar is depressed the pin can enter a tooth space of a pinion (11), locking the drive. When a workpiece is placed in the vee block the plates (2, 3) are forced outwards against spring tension, the crossed rack drive ensuring that the vertical plane of the vee axis remains unchanted. As the workpiece enters the stepped region of the vee the bar is depressed, causing the plates to lock. USE/ADVANTAGE - Machine tools, FMS etc. Rigid support of racks ensures free movement.

An optical interference system is also claimed, comprising one or more superimposed dielectric and/or metallic layers. The system has a layer holder which exposes the optical functional surface of the layer system, and which is only attached to the edge area of the layer system. Pref. the base layer comprises sodium or potassium chloride. The substrate is glass. The layer holder is a glass ring. Pref. the layer stack is mfd. by the evapn. of the sub-oxides SiO and TiO from SiO2 and TiO2 in a hydrogen atmos. at 10 power (-2) Pa at a substrate temp. of 20 deg.C. A water-soluble base layer of NaCl or KBr is applied to the glass substrate before this evapn. Hydroxides are formed with the TiO and SiO due to the presence of hydrogen; these are cross-linked by annealing at 400 deg.C. A ring-shaped glass holder is then bonded to the system using an epoxy-resin. The base layer is dissolved in water, and the layer stack and layer holder are removed from the substrate.
