Title: Microphone with frequency pre-emphasis
IPC: H04R17/02
Filed: 1988-12-01
Abstract: A stepped frequency microphone 
particularly adapted to a hearing aid 
application provides a stepped frequency 
and has a low-pass sonic attenuator for 
providing to the undriven side of the

Patent EP-0314333-A3 (EP)
IPC: G05B19/401
Filed: 1988-10-10
Abstract: The measuring apparatus is used on a numerically controlled 
machining station and comprises an arm (60) carrying at one end a 
sensor (55) for measuring the machining dimension in an operation of 
semifinishing a component (40) with an adjustable tool (50). The 
arm is mounted on the operating headstock (12) of the machining 
station and is rotatable about an axis which is perpendicular to 
the axis of the spindle. By rotating the arm from a rest position 
to a measuring position in which the sensor (55) is disposed in 
axial alignment with the tool (50) or parallel thereto it is 
possible during the machining operation to measure the dimension 
machined by the tool (50) without removing the tool from the spindle 
(13) of the headstock (12), or removing the component (40) from its 
own fixing support. Measurement in respect of the dimension being 
machined is effected before the last finishing pass and makes it 
possible to calculate possible correction to be made to the tool for 
finishing the machining operation with precision.

Title: Head-up display
IPC: G02B27/00
Filed: 1988-12-08
Abstract: In a conventional head-up display for a curved 
windscreen, the light beam containing the image of the 
display must be pre-distorted before it impinges on the 
windscreen so that a collimated, non-distorted image is 
reflected to the driver. The invention uses a 
transmission holographic system 8 in place of correcting 
optics and consists of two holograms, one of which 
corrects for chromatic aberration to permit the use of a 
filtered incoherent source to illuminate the display.

Title: Process for forming a polyimide pattern on a substrate
IPC: H01L21/768
Filed: 1989-04-25
Abstract: A polyimide pattern is formed on a substrate by providing 
a layer of photosensitive polyimide precursor containing 
the polyimide precursor and a compound having a 
photosensitive group on the substrate and prebaking the 
layer. The layer is then exposed imagewise to actinic 
radiation through a photomask to form an exposed image 
pattern of the polyimide precursor in the layer. The 
unexposed areas of the layer are removed using a liquid 
developer and the exposed image pattern is cured by 
heating. In one aspect of the present invention, the 
prebaking step employs a judicious selection of times 
and temperatures to eliminate the problem of formation 
of a white residue that occurs from using prior art 
prebake procedures. In another aspect of the present 
invention, a particular liquid developer composition is 
employed to facilitate the formation of sloped vias in 
the polyimide. In another aspect of the present 
invention, a particular range of exposure wavelength(s) 
is employed to obtain smooth walled vias.

membrane use; (4) passing the formed membrane through a 
quench zone wherein the mixture undergoes phase 
separation, and the major portion of the solvent is 
removed from the formed membrane, wherein the membrane 
formed is a membrane with a discriminating region 
capable of separating oxygen from nitrogen. Such 
membranes have excellent mechanical and thermal 
properties.

Filed: 1989-10-10
Abstract: A fixing device (1) comprises a body (2) having a 
rear surface (4) from which extends a double key hole 
shaped boss (5). A pair of pins (7,8) project from the 
boss and receive therebetween a locking member (9) which is 
secured to the body member by a screw (10). In a first 
limit position (Figure 1) the locking member abuts the pins 
so that the fixing device may be offered up to a pair of 
panels having aligned double key hole shaped openings to 
pass the locking member (9) through the openings and leave

the corners (13) of the pins (7,8). Continued rotation of 
the screw draws the locking member (9) towards the body 
member (2) to clamp the panels therebetween. The fixing 
device requires access only to one surface of the panels 
being clamped, and requires only appropriately shaped 
openings in the panels.
