Abstract: A belt tension detecting apparatus and a child seat provided with the belt tension detecting apparatus. A tension indicator includes a roller arranged on a belt at a midsection in the direction of extension thereof, a case accommodating the roller so as to be capable of rotating in the belt retracting direction and in the belt withdrawing direction, and a spring which urges the roller in the belt retracting direction. The roller includes a slit through which the belt passes. When a tension equal to or larger than a predetermined value is applied to the belt, a different color portion is seen through a window to indicate that the roller is rotated in the belt withdrawing direction.

Abstract: First, a board is placed on a board mounting portion with a lower mold and an upper mold being opened. Then, a resin material having such size and shape that correspond to the size and shape of a cavity formed in the lower mold is fitted in the cavity. Thereafter, the resin material is heated resulting in melted resin. Thereafter, the lower mold and the upper mold are closed, with a space formed by the upper mold and the lower mold being reduced in pressure. As a result, chips and wires are immersed in the melted resin. Thereafter, the melted resin is set, so that a resin mold product including the board and the set resin is formed.

Abstract: A method determines a plurality of clock delay values. Each delay value is associated with a delay element on a clock line leading to a clock sink in a synchronous circuit. The method determines an initial set of delay values and executes an optimization algorithm, beginning with the initial set of delay values, to arrive at a set of delay values that at least approximately meets an criteria while satisfying timing constraints associated with selected pairs of logically connected clock sinks. In a preferred form, the optimization algorithm is a genetic algorithm or a gradient descent algorithm. The genetic algorithm involves selecting parent sets of delay values, crossing over so as to produce a child set of delay values, mutating the child set of delay values, evaluating how well the child set of delay values meets the criteria, and conditionally discarding the child set on the basis of the evaluating step.

Abstract: A child seat device is formed of a base to be placed on a seat of a car, a child seat body placed on the base, and a connecting member for connecting a rear bottom of the child seat body to a fixed portion. The connecting member increases a length thereof while absorbing a kinetic energy of the child seat body when a tension higher than a predetermined value is applied thereto from the child seat body.

Abstract: In a child seat device, a child seat body is connected to a base while a bar disposed at the front bottom thereof is engaged with a guide member disposed at the front of the base, and the child seat body is pivotally supported on the arms standing at the rear of the base via shafts on the right and left rear sides thereof. The guide member extends forward and upward from the front of the base. The bar is movable along the guide member. In the case of a head-on collision of the car, the child seat body pivots on the shafts, so that the bar swings along the guide member to reduce the load to be applied to a passenger.

Abstract: A system and method is provided for controlling clock skew to meet timing constraints for a semiconductor integrated circuit. On-chip self-tuning circuits can be connected to each latch in the integrated circuit for controlling clock skew. Each self-tuning circuit delays a clock signal that is input to a latch when the clock skew does not satisfy the timing constraint for that latch. The self-tuning circuit repeatedly delays the clock signal until the clock skew is satisfied or until the delay becomes greater than or equal to a predetermined threshold. The delayed clock signal is then pushed to other latches in the integrated circuit until all the timing constraints for the integrated circuit are satisfied.
