Title: Electronically controlled transmission and steering wheel located shift mechanism
IPC: B60W30/18
Filed: 1991-05-10
Abstract: An electronically controlled transmission in which a shift actuator for driving a sleeve of a roller synchro mechanism and a throttle actuator for an engine are electronically controlled. The shift actuator is comprised of a drum type actuator of a simple structure comprising a shift drum and a shift fork. The use of the roller synchro mechanism ensures that only a small driving force for the shift drum is required, which makes it possible to provide a reduction in size of the shift actuator. In addition, a shift lever for operating a shift switch for producing the shifting instruction signal is mounted on either left or right side of the steering wheel. This ensures that the shifting-up and shifting-down signals can be produced by one of the driver's hands, leading to an improvement in operability of the shift lever. <IMAGE>

Title: Chest enclosures for ventilators
IPC: A61H31/02
Filed: 1992-03-27
Abstract: A chest covering shell (40) of springy material for fitting over a patient's chest is coupled to an air oscillator. Changes in air pressure in the shell (40) cause ventilation of the patient. The shell (40) is used with a backing pad (58) or back plate which has vertically extending supports (66) for engagement with the sides of the shell (40) so as to support them and prevent their flexing during use. The edge of the shell (40) has a seal (50) which runs continuously around the periphery of the shell (40). The seal (50) can include an inwardly directed flap in order to provide an effective seal when positive pressures are applied under the shell (40). The backing pad (58) can be an evacuatable envelope (62, 64) containing a multitude of small particles. In use the backing pad (58) can first be conformed to the shape of the patient and then made stiff by extracting the air from the envelope (62, 64) through an air outlet (70). <IMAGE>

Title: Method and circuit arrangement for measuring the temperature of a barrier layer of a GTO thyristor.
Inventor: HAUSWIRTH CHRISTIAN
IPC: G01K7/01
Filed: 1994-07-08
Abstract: A method and a circuit arrangement are specified having a device for measuring the barrier layer temperature of a GTO [gate turn-off thyristor]. In this case, a measuring current (IM) is impressed in the gate circuit and, after the decay of the transient turn-off processes, the voltage (UGR) between the cathode and gate is measured in the presence of the measuring current (IM). This voltage (UGR) is dependent at this point in time on the barrier layer temperature of the GTO. It thus becomes possible to measure the barrier layer temperature directly on the element, that is to say without diversions via cooling body temperature and calculation of the thermal resistance or the like, and continuously during operation and, as a consequence, to monitor and to control precisely the load factor of the GTO. <IMAGE>

Title: Identification pattern for image tube components.
Inventor: KUNZMANN MARTIN
IPC: H01J9/00
Filed: 1994-08-31
Abstract: It is known to provide image tube components with identification patterns. According to the prior art, this identification of image tube components is carried out in such a manner that there are applied on the outside of the glass troughs (10) layers or labels which are particular to the cone and contain the identification data. Due to the additional layers or labels, this technique is, however, exceptionally costly, so that the object consisted in simplifying this method. According to the invention, it is specified to form the respective identification pattern (16) directly in a first function layer which is supported on the inside (19) of the respective image tube components. The method can be carried out in a particularly simple manner when the respective identification pattern (16) is burnt into the first function layer with the aid of the laser. <IMAGE>

Filed: 1996-04-09
Abstract: The present invention is characterized in that it comprises signal detecting means located before the automatic transmission mechanism for detecting the timing that torque outputted from a torque converter of said automatic transmission at the moment of shifting up changes from clutch before shift to clutch after shift, signal detecting means located after the automatic transmission mechanism for detecting the timing that torque outputted from a torque converter of said automatic transmission at the moment of shifting down changes from clutch before shift to clutch after shift, and means for executing said driving shaft torque control in response to the changes in said both torque signal detecting means. The present invention may detect accurately the moment in which driving shaft torque is most controllable, i.e., the clutch shifting timing so that shocks of gear change may sufficiently be suppressed. Also, as said starting timing of the compensatory control of torque matches with detecting means for detecting clutch shifting, experimental matching for each shift is not required and experimental steps may be eliminated. <IMAGE>
