Abstract: During operation, large tensile stresses act on the insulating region under the base metallization with external electrodes on piezoceramic multilayer actuators. Since this insulating region forms a homogeneous unit together with the base metallization and the interconnecting layer, this fails when the tensile strength of the weakest element is exceeded and cracks develop. The cracks running unchecked through the insulating region are very critical, since they reduce the insulation distance and seriously increase the probability of actuator failure due to flashovers. According to the invention it is therefore proposed that, in the inactive region (14), the surface (10) of the multilayer actuator (1) has a pattern (18) that is produced by erosions (19) interrupting the surface (10), and that the base metallization (11) is deposited exclusively on the surface (10) left by the pattern (18).

Abstract: A vertical type forming, filling and sealing machine according to the present invention includes a film shaping mechanism for forming long lengths of film into tubular shapes, a vertical sealing mechanism for heat sealing the edges of the film formed by the film shaping mechanism in the longitudinal direction of the film to form tubular film, a supply nozzle for supplying contents into the tubular film, and two horizontal sealing mechanisms for heat sealing the tubular film in its width direction. A first horizontal sealing mechanism heat seals opposing inner surfaces of the tubular film except for a portion in the width direction. A second horizontal sealing mechanism is placed below the first horizontal sealing mechanism and heat seals the area which is not heat sealed by the first horizontal sealing mechanism.

Abstract: In a process for separating propylene from a mixture comprising propylene and propane, the mixture is passed through a bed of an adsorbent comprising a porous crystalline material having (i) a diffusion time constant for propylene of at least 0.1 sec−1, when measured at a temperature of 373° K and a propylene partial pressure of 8 kPa, and (ii) a diffusion time constant for propane, when measured at a temperature of 373° K and a propane partial pressure of 8 kPa, less than 0.02 of said diffusion time constant for propylene. The bed preferentially adsorbs propylene from the mixture. The adsorbed propylene is then desorbed from the bed either by lowering the pressure or raising the temperature of the bed.

Abstract: A semiconductor package includes a substrate, a chip and a marking film. The semiconductor chip is electrically connected to the substrate. A marking film is formed on the back surface of the chip. Thereby, a mark is formed by patterning the marking film. Generally, the marking film is a dry film or a tape. Not only the marking film prevents the singulated chips from being in a fry-chip manner but also can be patterned by laser ablation instead of the conventional method of forming a mark directly on the back surface of the chip. Accordingly, the chip will be prevented from destroying in the duration of performing the marking process.
