Abstract: A solid state touch or push button assembly ( 10 ) particularly for elevators, with no moving button parts and operated by capacitive sensing, either as a constant pressure or a auto balancing button. When one touches or pushes on the button, the capacitance is changed and sensed. When so changed, the circuitry causes the electrical or electronic function controlled by the touch button to be activated (or deactivated, depending on the design, or otherwise altered). An annular ring of LEDs ( 3 ) located in a light ring ( 2 ) surrounding the touch button surface ( 1 ) are concurrently activated, providing visual feedback to the button pusher. The light ring includes at its bottom underside an alternating series of triangular, sawtooth or grooved, light entry, diffusing surfaces, with each LED crowned by three such surfaces forming a chamber ( 24 ), producing a relatively even, bright, light distribution or halo from the encircling ring surface ( 2A ) surrounding the touch button surface. The chambers lead into a solid, transparent, light-pipe­like upper portion ( 27 ), which transmits the light coming in from the chambers to the encircling ring area sur­rounding the button surface. The LEDs are carried on a PCB base ( 23 ), which is carried by and keyed to the bottom of the molded body portion of the light ring.

Abstract: 2.1. To form production lines, production stations (22) combined to form individual production areas (21) are interlinked by a conveying section (20). The conveying section (20) conveys the workpieces, arranged on work carriers (23), at the same speed from one production station (22) and one production area (21) to the other. The naturally limited conveying speed on the conveying section (20) necessitates long ancillary times which result from the further transport of the work carriers (23) from one production station (22) to the other. Such production lines are consequently uneconomical. 2.2. To provide more economical production lines, the work carriers (23) are moved further at a preferably higher speed at least through the production area (21). For this purpose, an appropriate device has an auxiliary conveyor (24) in the production area (21). 3. The invention is especially suitable for production lines in the automobile industry, namely for the production or assembly of engines or gearboxes. <IMAGE>

Abstract: A learning machine has plural multiple-input single-output signal processing circuits (3) connected in a hierarchical structure. The learning machine sets a threshold value, which is a evaluation standard for change in weight coefficients, high during the early part of the learning process and enables rough learning to progress without changing the weight coefficients for those multiple-input single-output signal processing circuits (3) for which errors are sufficiently small. On the other hand, the learning machine gradually reduces the threshold value as learning progresses and advances learning by a non-linear optimization method (including a conjugate gradient method, a linear search method, or a combination of conjugate gradient and linear search methods) during the later part of the learning process, and thereby improves the learning speed.

Abstract: It is well-known to use large baths for applying developer solution to a photographic material. However, excess amounts of the developer solution are required to produce the desired results. Described herein is a coater arrangement in which developer solution can be coated on to a photographic material at a rate which does not exceed the maximum swell rate of the material. This allows developer solution to be applied to the photographic material without leaving behind liquid effluent. The coater features a delivery channel (32) leading from a manifold chamber (30) to a slit orifice(34), the channel (32) being improved in that it contains a plurality of spaced-apart wall portions (38) connecting the opposed flow surfaces (35, 36) of the delivery channel (32) which extend in a direction towards the slit orifice (34). A further structure is provided inside the orifice (34) for coalescing the individual streams fed by these wall portions (38) into a continuous strip of liquid to be dispensed by the slit orifice (34).
