Patent EP-0347993-A3 (EP)
IPC: H03B5/18
Filed: 1989-06-19
Abstract: In a microwave oscillator device, wires (1,2,3 etc) form 
inductors in a feedback path between a control electrode (e.g. 
gate) and a second main electrode (e.g. source) of a transistor 
(e.g. a GaAs MESFET). The transistor body (10) is mounted within 
an insulating surround 25, on a base 21 providing a first device 
terminal. The connection to the second main electrode comprises 
in series at least first and second lengths (1,2) of wire, 
whereas the connection to the control electrode comprises a third 
length (3) of wire. The invention permits the construction of a 
mechanical and electrical replacement for a Gunn diode by 
compressing the wire lengths (1,2,3 etc) in a particular 
arrangement into the small space inside a conventional Gunn diode 
envelope (20). The first wire length (1) and possibly more 
lengths are arched onto a low bonding area (15,16,17) adjacent 
the base (21), where the second and third wire lengths extend 
upto an upper bonding area (23) adjacent the top of the surround 
(25) and connected to the second terminal (22). The resulting 
inductance of the connection (1,2, and possibly 4) between the 
second main electrode and the second terminal (22) is higher than 
the inductance of the connection (3) between the control 
electrode and the second terminal (22), whcih provides an 
impedance level equivalent to that of the Gunn diode which the 
device replaces.

Title: Switch control for a self propelled floor transportation vehicle
IPC: B61L11/02
Filed: 1990-12-05
Abstract: A switch control for a self-propelled floor transportation vehicle is known, which has a guide shoe which engages in a guide rail. The guide shoe can be laterally displaced with respect to the travel direction so that a desired travel direction can be selected at a fork. The known switch control operates with electromagnets which are arranged on the floor area and act on the guide shoe. If the electromagnet is activated, this leads to the guide shoe swivelling. However, the use of electromagnets in the floor area requires a high degree of expenditure. Therefore, it is proposed to provide fork signalling elements in the floor area, which elements are evaluated via sensor elements in the floor transportation vehicle and actuate drive units for the guide shoe.

Patent EP-0542702-A3 (EP)
IPC: G10B3/12
Filed: 1992-11-13
Abstract: Beneath each key and carried by the keyboard support there is a basically round-shaped elastic or elasticized element, the base of which lies on the keyboard support, such a round-shaped surface, which may be achieved by hot-pressing a rubber sheet, and on top of which there is a collar the aim of which is to provide a certain resistance to the key, thus distributing the deformation resistance to the key, thus distributing the deformation caused by the pressed key over the entire surface of the round-shaped element. In other words, the top collar, under the effect of the pressed key, moves parallel to itself, thus causing the uniform deformation of the entire rubber element. The keyboard support consists of a board or plate on which a layer of plastic material is injected in such a manner as to cover the edges and the ends of the board or sheet, while leaving the middle parts uncovered, thus forming a sort of grid.
