Title: Lift control system
Inventor: KIRKE JEFFERY STEVENS
IPC: B66B5/00
Filed: 1988-06-17
Abstract: A computer (13) produces signals indicative of desired lift car movement on lines (m, u, d, f, s) to a fixed logic memory device (12). Proivded the signals are valid, the device (12) produces signals on lines (M, U, D, F, S) to triacs (37, 38, 39, 40, 41) (if invalid, an error signal is generated instead). The triacs switch current to servo solenoids in contactors (33, 34, 35, 36) to cause these to direct electric power to the lift's motor (7) for appropriate, desired movement of the lift car. Alternatively the lift is hydraulically driven and servo valves replace the contactors (33-36). The device (12) may be an EPROM, a fusible link ROM, a PLA or PAL (Programmable Logic Array). The system may include a building computer and a car computer, one slaved to the other; and with the car computer controlling the car door opening motor through a further fixed logic memory device. <IMAGE>

Title: Operation control device for washing machines
Inventor: IMAI MASAHIRO
IPC: D06F34/08
Filed: 1991-08-27
Abstract: An operation control device for a washing machine incorporating equipments such as a motor (4) and electromagnetic valves (2, 3) includes a sub-microcomputer (13) for controlling the equipments incorporated in the washing machine and a host microcomputer (12) supplying control commands to the sub-microcomputer (13) to control the same. The host microcomputer (12) is provided with a first function of determining whether or not a control sequence of the washing machine has reached a stage where the incorporated equipments are to be controlled by the sub-microcomputer (13) and a second junction of supplying a reset signal to the sub-microcomputer (13) to reset the same when a result obtained by the first function signifies a negative. This reduces the probability of runaway of the sub-microcomputer (13). The sub-microcomputer (13) checks for interruption of longer than a predetermined time of the control commands supplied from the host microcomputer (12), to detect runaway of the host microcomputer (12). The correctness of the control commands supplied to the sub-microcomputer (13) is checked. An output of the submicrocomputer (13) is coated with an output of the host microcomputer (12), to detect abnormality of either microcomputer. A data transfer preparation command signal causes defective transmitted data to be cancelled and correct data to be restored. <IMAGE>

Title: I.c. engine ignition timing control system
Inventor: KITAGAWA HIROSHI
IPC: F02D43/00
Filed: 1991-12-16
Abstract: An ECU sets a basic spark advance value in response to operating conditions of the engine, corrects the set basic spark advance value, and limits the corrected value in a spark retarding direction to a limit value. The ECU further detects operating conditions of a valve timing changing system 16 which changes the valve timing of at least one of an intake valve 1a and an exhaust valve 1b of the engine, and is responsive to the detected operating conditions of the valve timing changing system for changing the limit value, e.g. in such a manner that when low-speed valve timing is selected, the limit value is more advanced than that set when high-speed valve timing is selected.

Title: Lock-up torque converter for automatic transmission
Inventor: KOHNO SATOSHI
IPC: F16F15/134
Filed: 1992-05-28
Abstract: A pump 5 is fixedly connected to the crankshaft 1 of an internal combustion engine and a torque converter cover 12 is connected to a converter output shaft 7 during a lock-up condition. A shock absorbing member, such as a spring 11, connects the pump 5 and the converter cover 12 resiliently in the rotating direction of the converter output shaft 7. Accordingly, fluctuations of the engine speed and of the output shaft speed are absorbed by the pump 5 and the converter cover 12, respectively, and therefore torsional vibrations and noises generated in the passenger compartment are suppressed. <IMAGE>

Title: Microwave determination of gas and water content of oil
Inventor: CRACKNELL DAVID JOHN
IPC: G01N22/00
Filed: 1992-10-15
Abstract: The proportions of gas, water and oil in a fluid flow along a conductive pipe 11 are measured by projecting microwave radiation at at least two frequencies along the pipe with the pipe acting as a waveguide, detecting radiation which has passed along the pipe and calculating the relative proportions of gas, oil and water from measured insertion loss, insertion phase and time delay. As shown, microwaves are injected at electrodes 16 and received at sets of four electrodes 12B, 13B, 14B, 15B and 17, spaced around and along the pipe, electrodes 12B - 15B being located in smaller concentric pipes 12, 13, 14, 15 of progressively decreasing radii. Five microwave frequencies are injected sequentially and the proportions are determined from the transmission conditions in each of the pipe sections at each frequency. <IMAGE>

Title: Vehicle-mounted charging apparatus for a portable telephone set
Inventor: KUNITOMO KOUICHI
IPC: H02J7/02
Filed: 1992-12-07
Abstract: The charger 17 has a microcomputer 111 which controls the level of current provided by a supply circuit 18, 19. 20 in dependence on data received from the telephone set 11 indicative of the type of battery 12 connected and of whether the telephone set is in a communicating or noncommunicating state. The current provided by circuit 18, 19, 20 is thereby established at a level sufficient not only to charge battery 12 but also to operate the telephone set when in a communicating state. This avoids use of separate charging and telephone operating current supply circuits in charger 17 and also avoids use of an internal/external power supply detector switch (25), (Fig 2), in the telephone 11. Telephone 11 has an internal circuit 14 with a microcomputer which supplies communicating/non-communicating state data to the charger microcomputer 111 and may also supply the battery type data; alternatively microcomputer 111 may receive battery type data from a terminal 13 of the battery 12. <IMAGE>
