Inventor: KADOTA YOICHI
IPC: F02D35/02
Filed: 1997-09-30
Abstract: The apparatus includes an intake suction amount sensor which detects the parameter relating to the intake suction amount of an internal combustion engine.

Inventor: LUTSCH WILHELM
IPC: E01B25/26
Filed: 1998-02-19
Abstract: The invention relates to a switch point for a conveyor device in which carriers (17) for material to be conveyed which are fitted with rollers (31, 33) are movably guided on running rails. The switch point has a switch point blade (13) which can be switched between a first and a second position, in the first position joins a connecting end (45) of a first running rail section (7) with a connecting end of a second running rail section (9), and in the second position is separated from the first running rail section (7). A securing device (43) comprises a locking element (47) which is arranged on at least one supporting element (5) near the connecting end (45) of the first running rail section (7) and can be moved between a locked position and a release position. When the connecting end (45) of the first running rail section (7) is open the locking element is in the locked position to prevent carriers (17) for the material to be conveyed from moving towards the connecting end (45) of the first running rail section (7). When the first switch point blade (13) is moved into its first position the locking element engages with a part of the first switch point blade (13) and is forced into the release position by said first switch point blade (13), so that the locking element (47) moved into the release position allows the carriers (17) for the material to be conveyed to pass freely.

Patent DE-19818527-A1 (DE)
Title: Method of operating several data terminals at a standard control unit
Inventor: STAERKER ROLF
IPC: G05B19/042
Filed: 1998-04-24
Abstract: The method involves connecting all terminals (DG1-DGn) via a common first bus line (BL1) to a digital data input and via a second common bus line (BL2) to a digital data output of a standard control unit (STE).  All terminals are allocated a fixed position in a predefined sequence.  Data transfers are controlled using a clock with a predefined period.  Data can be passed to the terminals via the control unit output using 2 start bits, data bits and a stop bit. Single bits are sent at intervals when no data are being sent.  The terminals are synchronized using the output signal sequence. The first terminal is notified of access and sends a first start bit when wishing to send data.  Each terminal monitors the signal sequence to determine whether the first terminal sends a start bit; if not it can send a start bit if wishing to send data and so on. An Independent claim is also included for a data terminal.

Patent DE-19826719-A1 (DE)
Inventor: KIENZLER DIETER
IPC: F02M47/02
Filed: 1998-06-16
Abstract: The invention relates to a valve control unit (1) for a fuel injection valve, comprising two communicating valve control chambers (5, 8). The end member (13) of a valve control piston (3) that may be impinged upon with pressure is located inside the first valve control chamber (5) that is connected to a supply channel (6). Said member can be displaced in such a way that the flow cross section for fuel exchange may be shifted from the first valve control chamber (5) to the second valve control chamber (8) that is connected to a drain channel (9). A throttle channel (17) for fuel exchange between the valve control chambers (5, 8) is embodied in the end member (13) of the valve control piston (3). Due to the configuration of the throttle channel (17), mechanical stop of the end member (13) of the valve control piston (3) is made possible on the edge areas of the passage between the valve control chambers (5, 8). The stop makes it possible to enlarge the volume of the first valve control chamber (5), said volume enlargement having no negative effect on the performance of the stop of the end member (13). Increased reaction speed of the valve control piston (3) after conclusion of the injection process can be obtained as final result of these constructional measures.
