摘要:
A navigation apparatus has an information taking-in means for taking-in road-in-facility information, which indicates roads placed in a facility and is supplied from the outside, and a displaying means for displaying a location map according to the road-in-facility information read out from the information taking-in means and for-navigation location map data read out from a storing means and displaying a position of a driver's car and a guiding route on the location map.

A power supply unit has an overdischarge detection circuit for detecting overdischarge of a power source, an overcurrent detection circuit for detecting overcurrent, and a stopping circuit for stopping overdischarge or overcurrent in accordance with an overdischarge detection signal or an overcurrent detection signal. The power supply unit is further provided with a delay circuit to prevent the overdischarge detection circuit and the overcurrent detection circuit from being activated erroneously by external noises. This delay circuit provides a variable delay time so that the delay time will be longer when overdischarge is detected than when overcurrent is detected. This makes it possible to stop overdischarge and overcurrent without fail.

An IC type stabilized power source circuit being provided with n pieces of output transistors, each outputting to a common terminal; n pieces of over current detection circuits provided for the n pieces of the respective output transistors and outputting respective detection signals when the output currents flowing through the respective corresponding output transistors exceed predetermined rated current values set for the respective corresponding output transistors. N pieces of control circuits are provided for the n pieces of the over current detection circuits and when receiving the respective corresponding detection signals, each limiting the output currents to the respective corresponding output transistors in relation to the over current detection circuits from which the detection signals are received to respective values equal to or less then the respective predetermined rated current values.

A rotating member supporting apparatus has a rotating shaft which is inserted to a bore formed in a support member. A rolling bearing is interposed between the rotating shaft and support member and rotatably supports the rotating shaft. The bearing includes an inner and outer rings which have resistance to heat and corrosion, and a plurality of rolling elements rollably arranged between the inner and outer rings. The rolling elements are formed of ceramic material.

An improved method of fabricating electrodes used in nickel-cadmium storage batteries, etc. A pasty mixture is sprayed from both sides onto a porous metal body having three-dimensional communicating spaces so as to fill the pasty mixture, which has been previously prepared, into the spaces of the porous metal body with good reproducibility. The amount of active material filled into the spaces can be easily controlled. Thus, electrodes having a desired capacity can be mass-produced.

A process for producing ceramic products such as turbine rotors comprises the steps of contouring a prefired ceramic roughly or primarily formed workpiece into a desired shape by means of a rod-shaped cutting tool having a working end or tip to which abrasive particles have been secured, said tool being rotated about its axis; subjecting the contoured surface of said workpiece to an abrasive finishing; and thereafter firing said workpiece thus finished.
摘要:
In a data processing system having a plurality of virtual address spaces, a virtual address is translated into a real address for accessing a main memory and the translation result is stored in a translation lookaside buffer, as in a processing system having a single virtual address space. Thereafter, in the case of the same virtual address as the above, the translation lookaside buffer is retrieved to translate the virtual address into a real address. Generally, even in the case of the same virtual addresses, if their virtual address spaces are different, the virtual addresses are translated into different real addresses. However, a control program, a control table or a common subroutine is provided in a common area in which the coordination of virtual and real addresses is always constant even in the case of different virtual address spaces. To enhance the efficiency of utilization of the translation lookaside buffer, common area indicating means is provided, by which the coordination of virtual and real addresses on the translation lookaside buffer is registered so that it can be used in common to a plurality of virtual address spaces.
摘要:
The battery charger is provided with a holding cavity 2 that allows a first rectangular battery pack 30 and a second rectangular battery pack 40 to be loaded in a detachable fashion. The holding cavity has a rectangular opening and has first charging terminals 5A to contact first rectangular battery pack electrode terminals 32, and second charging terminals 5B to contact second rectangular battery pack 40 electrode terminals 42 established on a first perimeter wall 4A and second perimeter wall 4B, which are perpendicular. The battery charger charges the first rectangular battery pack through the first charging terminals when it is loaded in the holding cavity with electrode terminals 32 in contact with the first charging terminals. The battery charger charges the second rectangular battery pack through the second charging terminals when it is loaded in the holding cavity with electrode terminals in contact with the second charging terminals.
