Abstract: This invention provides a new production scheduling system. The system includes a technique that utilizes a knowledge base system to dynamically schedule production of parts on a plurality of manufacturing machines. The schedule is updated dynamically to conserve synergism with the changing environment. The schedule is created to conform with predefined rules to conserve constraints imposed by the machinery to create parts of different specifications. The rules may be hard in that they may be specifiable in mathematical terms or they may be heuristic and soft in that they may be allowed to be relaxed as determined by operators who have learned from experience with the production machinery. Finally, the invention allows interactive monitoring and adjustment of the schedule by an operator including selective seeding of the schedule.

Abstract: The posture of the automotive vehicle body is controlled by supplying or discharging the operating fluid to or from the cylinder unit (3) for each wheel, which is interposed between a sprang weight and an unsprung weight. When an incident occurs to such an extent that the control over the posture of the vehicle body cannot be implemented in a normal way, the control is suspended. When such an incident occurs during cornering of the vehicle body, the suspension of the control over the posture of the body is so modified as to implement a special control, preferably control being made so as to lower the vehicle height by forcibly discharging the operating fluid from the cylinder unit. This prevents the vehicle body from being leaned after the end of the cornering. A decision as to cornering is made by taking advantage of the state of operation of the steering wheel or the magnitude of transverse acceleration. Preferably, a decision is made to determine if the difference in inner pressures between the left-hand and right-hand cylinder units is a predetermined value or higher.

Abstract: A cast manifold for distributing pressurized melt in an injection molding system. The melt is received at a central inlet (94) on the rear surface (78) of the manifold to an inlet portion (92) of a melt passage (90). Four identical outlet portions (96) of the melt passage branch radially outward from the inlet portion (92) to equally radially spaced outlets (103) on the forward surface (128) of the manifold. Each outlet portion (96) extends around a first smoothly curved bend (98) from the inlet portion (92), along a radial portion (100), and then around a second smoothly curved bend (102) to the outlet. By casting on a removable ceramic mold, the bends (98,102) in the melt passage (90) are very smoothly curved and do not all have to extend in a common plane. Furthermore, the radial portions (100) angle a substantial distance rearwardly as they extend outwardly which allows the thickness of the manifold to be reduced.

Inventor: KOMATSU TAKAHIRO MITSUBISI DEN
IPC: G11C11/409
Filed: 1991-08-27
Abstract: A dynamic type semiconductor memory device includes m memory blocks (M1-M8; M1-M16) each having a plurality of memory cells, and a plurality of sense amplifier groups (SA1-SA8) associated with the respective memory blocks. Each sense amplifier group senses and amplifies data of a selected memory cell in the related memory block. The memory device further includes a circuit (30) for generating a refresh instruction detecting signal in response to an externally applied refresh mode indicating signal, and circuitry (4 and 20) responsive to a block designating signal and the refresh instruction detecting signal for activating each of the sense amplifier groups in such a manner that only start timings for the sensing operations of the sense amplifier groups related to the designated memory blocks may differ from each other. This activation circuitry activates the respective sense amplifier groups related to the memory blocks designated by the block designating signal in such a manner that their sensing operations may have the same start timing in the normal mode. This device significantly reduces current dissipation in the refresh mode, while the access time in the normal mode is not adversely affected. This device is suitable for use as an internal memory of a battery back-up type computer because of its small load on the battery.

IPC: H04J3/14
Filed: 1992-03-05
Abstract: Collisions can occur between data transmission blocks in the system communications channel (SYS-COM) of a flexible multiplexer, with the possible result that the block which is held up is the very one which is seeking to transmit an urgent alarm message to a controller (CTR). Furthermore, the controller cannot identify when a connection unit (TA1, TA2, LA) is missing. Both problems are solved with a request line (RL) which connects all connection units (TA1, TA2, LA) to the controller (CTR) in time division multiplexing. Each connection unit (TA1, TA2, LA) is allocated an individual time slot in which it can transmit a code word with alarm messages of different urgency to the controller (CTR). Conversely, the controller can poll the connection units (TA1, TA2, LA) for an exception code word which is transmitted only when a connection unit (TA1, TA2, LA) is missing. This method can be used in network termination multiplexers (NTMX). <IMAGE>

Abstract: When a zeolite additive composition of a mediumpore zeolite with a Constraint Index from about 1 to about 12 and a silica to alumina mole ratio greater than about 12 is added to a conventional cracking catalyst dispersed in an inorganic matrix, the octane will be improved, but there will be a yield loss in the amount of gasoline produced. An improvement in that catalyst system is obtained by partially exchanging the medium-pore zeolite additive with cations from one or more elements of Group IA, Group IIA or Group IIIA of the Periodic Table. The octane number of the gasoline-range product of an FCC process is still improved while the amount of the gasoline yield loss typically observed for such octane-enhancing additives is reduced.
