Title: Semiconductor device including overvoltage protective circuit
Inventor: KUMAGAI NAOKI
IPC: H01L21/822
Filed: 1992-12-31
Abstract: In a semiconductor device including a switching device (1) such as a MOSFET or an IGBT, and an avalanche device (2) protecting the switching device by generating an avalanche current when overvoltage is applied to the switching device, the avalanche device shares a drift layer (10) with the switching device. With this arrangement, the avalanche voltage of the avalanche device follows the changes in the withstanding voltages of the switching device due to the variations in the thickness or impurity concentration of the epitaxial layer or temperature. This makes it possible to reduce the margin between the avalanche voltage of the avalanche device and the withstanding voltage of the switching device, and to protect the switching device from damage. <IMAGE>

Title: Bell striker mechanism
Inventor: AMLANI MANHER
IPC: G10K1/064
Filed: 1993-06-07
Abstract: A bell striker mechanism has an armature (12) biased by a spring (28) towards a bell (18). The armature (12) extends within a coil (10) and energisation of the coil (10) causes the armature (12) to be moved away from the bell (18). When energisation of the coil (10) stops, the armature (12) is propelled by the spring (28) to contact the bell (18). Thus, repeated energisation and de-energisation of the coil (10) causes the bell (18) to sound. The spring (28) has an adjustment member in the form of a cap (22) threadedly mounted in a barrel (20). By movement of the cap (22) in the barrel (20), the rest position of the armature (12) can be adjusted, thereby permitting the relative positions of the armature (12) and bell (18) to be adjusted to give satisfactory sound. <IMAGE>

Title: Method of generating a tyre pressure warning signal.
Inventor: BABBEL ECKHARD
IPC: B60C23/06
Filed: 1993-09-10
Abstract: A method of generating a warning signal in the event of an undesired pressure drop in a tyre of a travelling vehicle operates with detection of the rotational speeds of the wheels of the vehicle as a criterion for a pressure drop. To generate the warning signal, the rotational speed signals are fed to a filter (10) for summing storage. The prevailing summation value is evaluated in a computing stage (11), possibly for generating the warning signal. It is ascertained by means of fuzzy logic (5, 6, 7) in accordance with plausibility principles whether changes in the rotational speed signals are to be associated with acceleration of the vehicle or a tyre defect. In the first case, the signal path to the filter (10) is interrupted, or the signals are subjected to attenuation, so that they are weighted to a lesser extent. However, the summation value previously ascertained in this stage (10) is not erased, so that, if need be, a warning signal is generated very rapidly after a travelling operating state with acceleration has ended. <IMAGE>
