Patent EP-0379026-A3 (EP)
IPC: H04B10/14
Filed: 1990-01-08
Abstract: Laser diode transmitters contain control circuits for the preconduction current and the modulation current of the laser diode which are controlled via a monitor diode optically coupled to the laser diode. Disablement of the monitor diode may result in an excessively low optical transmission level being deceptively simulated for the control circuit and the modulation current of the laser diode then being increased to the point where the latter is endangered. According to the invention, an improved laser diode transmitter is described which protects the laser diode against excessively high modulation current and transmits an alarm signal to a monitoring device even if the monitor diode fails completely. <IMAGE>

Title: Voice recognition dialing unit
IPC: H04M1/2745
Filed: 1990-06-19
Abstract: A voice recognition dialing unit of a telephone mounted 
on a vehicle or similar mobile body and which allows a call to be 
originated with ease. When the user of the telephone enters a 
voice command on a voice inputting section, the dialing unit 
originates a call automatically and thereby connects the other 
party to the telephone line. In a call origination procedure, 
the operations for call origination and the verifications are 
performed between the user and the unit in an interactive 
sequence. In a preferred embodiment, the unit has a particular 
call origination procedure in which, when the other party 
recognized by the unit is wrong as determined by the user by 
verification, lower-place candidates for the other party are 
called up in response to a particular voice command. In an 
alternative embodiment, the unit indicates the other party by 
voicing a name for verification purpose. The alternative 
embodiment has means for selecting and storing only the name of 
the other party in response to an entered voice signal and, in 
the event of response for verification, combining the name having 
been stored in this means and response information stored 
beforehand to produce composite response voice.

Title: Process for making low optical density polymers and copolymers for photoresists and optical applications
IPC: C08F12/12
Filed: 1991-06-26
Abstract: Polymers comprising poly(4-hydroxystyrene) and/or substituted poly(4-hydroxystyrene) are produced by polymerizing 4-acetoxystyrene and/or substituted 4-acetoxystyrene monomers, with or without other comonomers, and subsequently performing transesterification. Preferably, the polymers are produced using at least one alcohol as a reaction medium, a chain transfer agent and a transesterification reactant. It is appropriate: to use an initiator which does not comprise a substantially absorbant structure over the 240 to 260 nm range or to use an initiator concentration of less than about 3 mole % of the monomer(s); to obtain a polymerization conversion of the initial polymerization monomers of at least about 90% by weight, or to remove residual monomer(s) from the reaction medium prior to transesterification; to obtain a transesterification conversion of the polymerized monomers of at least 85% by weight; and to avoid the use of transesterification catalysts which can cause the formation of chemical structures which can absorb over the 240 to 260 nm radiation wavelength range. The target polymers have low optical density (absorbance) over a wavelength range from 240 to 260 nm, as well as low optical density over the near UV and visible spectrum (310 to 800 nm); and are useful as photoresist components for use in combination with deep UV, X-ray, and E-Beam imaging systems.
