Abstract: An update map data acquiring means 6 for acquiring update map data is disposed in a navigation system. Even when a navigation function is being used by a control means 5 which controls the functions of the whole navigation system using yet-to-be-updated map data stored in a map data storing means 2, the control means updates the map data by writing the update map data from the update map data acquiring means 6 in a free space on the map data storing means 2.

Abstract: A navigation device includes a determination means which determines whether or not to activate tunnel mode function based on characteristic data of the tunnel read from the database, a vehicle speed detected by the vehicle speed detection means and a vehicle position detected by the vehicle position detection means, and a control means which displays characteristics of the tunnel to be travelled through on a display means based on a command signal from the determination means to activate the tunnel mode function and which activates various on-vehicle devices in the tunnel mode function.

Abstract: A multiplicity of shell eggs to be broken are first transported in transverse rows on an infeed conveyor, from which they are loaded onto a transfer conveyor. This transfer conveyor extends at a right angle to the infeed conveyor, so that the successive transverse rows of shell eggs on the infeed conveyor are rearranged into a longitudinal row on the transfer conveyor. The shell eggs are subsequently transferred from transfer conveyor onto respective egg breaker assemblies mounted at longitudinal spacings on an endless breaker conveyor, while the breaker assemblies are traveling side by side with the transfer conveyor. The breaker assemblies break the shell eggs, and the white and yolk recovered therefrom are separated by recovery cup assemblies also carried by the breaker conveyor under the respective breaker assemblies. As an incidental feature an air nozzle assembly is mounted on the breaker conveyor in the vicinity of each breaker assembly.

Abstract: Phase control device comprising a driven wheel and a driving wheel. The driven wheel engages an endless loop, whose going part toward the driving wheel and returning part from the driving wheel engage a pair of idling wheels and one or plural pairs of movable wheels. The movable wheels are finely adjusted toward a cross direction to the endless loop so that either the going part and the returning part is pulled, while the other is slackened. As a result, the phase of the driven wheel is changed so that timing of the driven wheel against the driving wheel can be regulated. The phase control device provides timing of the operation of a pair of machines such as coveyors which link mutually.

Abstract: A process for producing a crosslinked and foamed resin sheet which comprises shaping a resinous mixture comprising a thermoplastic synthetic resin and a heat-decomposable blowing agent into a sheet form, applying a high-energy ionizing radiation to the resulting foamable resin sheet to crosslink the resin sheet, and then heating the resulting crosslinked foamable resin sheet to the decomposition temperature of the blowing agent or to a higher temperature; wherein the high-energy ionizing radiation has a range of at least 0.7 .rho.d g/cm.sup.2 in which d is the thickness in cm of the foamable resin sheet, and .rho. is the density in g/cm.sup.3 of the foamable resin sheet, and a low-energy ionizing radiation with a range of not more than 0.6 .rho.d g/cm.sup.2 in which d and .rho. are as defined is applied to the foamable resin sheet before, during or after the application of the high-energy ionizing radiation.
