Abstract: In a die casting machine that includes a shot cylinder having a ram for injecting metal into a die cavity, an electrohydraulic system for controlling operation of the shot cylinder includes an actuator coupled to the shot cylinder ram. A valve supplies hydraulic fluid to the actuator cylinder as a function of valve control signals. Microprocessor-based digital control electronics includes memory for storing a desired ram velocity profile as an incremental function of ram position. The control circuitry is responsive to signals from a sensor coupled to the actuator, indicative of position at the ram, for retrieving corresponding velocity signals from memory and supplying control signals to the valve as a function of such profile velocity signals. The control circuitry further includes facility for adjusting impact of the shot cylinder ram at the end of a cavity-filling stroke as a function of ram and actuator position and/or pressure, independently of the velocity/position profile, to reduce separation and flashing at the die cavity, and to reduce impact wear and fatigue on the overall die casting machine. A keyboard and associated operator display provide operator programmability and selection from a plurality of velocity/position profiles. The actuator and cylinder ram may be advanced in a manual mode of operation for adjustment and calibration proposes. A display associated with the keyboard graphically illustrates desired and actual velocity/position profiles during operation, together with a profile of actuator drive pressure verses position.

Abstract: A central processor (ANSR), which is constructed with signal dependability, generates separate control instructions (T1, T2) for driving in each case a part of the luminous elements to be controlled (L1 and L2, L3 to L5) and transmits these via associated control modules (SB1.1, SB1.2) to the associated mosaic modules (M1) of the display panel. The association of the control instructions with the control modules is exchanged in cyclic alternation. The representation of an event conveyed to an observer is not changed by this as long as the device is operating correctly. When there are any drive errors, however, a flashing mode results in individual signalling fields which signals the fault occurrence. In one embodiment of the device having two luminous element pairs in each case per signalling point, it is provided to activate in each case all first luminous element pairs via one control module and to disconnect the other luminous element pairs during this time. Here, too, the association of the control instructions with the control modules is cyclically exchanged. When control instructions do not match for the two luminous element pairs of each signalling point, the signalling points affected by the disturbance flash in the rhythm of the change in the control instructions. A single-channel monitoring of the event is also possible for the case of the disturbance. <IMAGE>

Abstract: A voice processing device, such as a translation device based on voice recognition. The voice is inputted through microphone (10) while operation switch is held down. Voice recognition section (14, 20, 22) recognizes the word spoken in a certain language which is contained in this voice signal by searching voice recognition dictionary (22), and outputs an indication which represents the recognized word. The recognized word is visualized on display device (32). If the displayed word is what is wanted by a user, the user waits for prescribed duration (t0) from this point of time. When prescribed duration (t0) elapses, voice synthesis section (16) reads, decodes and decompresses the voice signal from translation dictionary (36) where the voice signal for the word expressed in other language is stored in the compression-encoded form, and vocally outputs it from speaker (12). Through this procedure, the word expressed in the different language is outputted from speaker (12), corresponding to the voice inputted through microphone (10). These vocally expressed words may be visualized on display device (32) by operating key (44). If the word, which is displayed on display device (32) by voice recognition, is not what the user wants, the user can operates key (44) to interrupt the voice, which is being outputted by voice synthesis section (16) and output prescribed common phrases in the vocal form. The word to be inputted may be a key word, and in this case, voice synthesis section (16) outputs the sentences associated with the key word.

Filed: 1991-10-08
Abstract: In a process for preparing a polyarylene sulfide by reacting an alkali metal sulfide and at least one dihaloaromatic compound in an organic amide solvent at an elevated temperature: a highly pure anhydrous alkali metal sulfide reactant having a purity of at least 95% by weight and a content of alkali metal hydrosulfide impurity of not greater than 2% by weight is employed. The water is deliberately added in a proportion of 0.1 to 0.8 moles per each mole of the alkali metal sulfide used in the process. The alkali metal sulfide reactant is charged in a concentration of 2.5 to 5 moles per liter of the reaction mixture. The deliberate addition of water enables one to omit a dehydration stage which has been desirably or rather necessarily effected to obtain a satisfactory polymer product where a hydrous alkali metal sulfide reactant is employed. The improved process of the invention provides a highly pure polyarylene sulfide product having a relatively increased molecular weight and a decreased content of by-product oligomers.

Filed: 1991-03-20
Abstract: A converting unit converts from multi-value image data per pixel to binarized image data per pixel with M pixels in a row direction and N pixels in a column direction. An image reducing unit reduces from the binarized image data of M pixels in the row direction and N pixels in the column direction to curtailed pixel data of m pixels in the row direction and n pixels in the column direction. The image reducing unit reduces the binarised pixel data using a pattern of curtailment pixel positions which are different for adjacent lines. As a result, a viewer of the curtailed pixel data does not sense gaps in the output image. (The illustration shows an example of a curtailment pattern for reducing A3 size pixel data to B4 size pixel data.)
