In an axle driving apparatus according to this invention, an input shaft is pivotally supported in a substantially horizontal fashion inside a housing, and projects outward on one side of the housing so as to receive power from a motor via a belt converter. Axles are pivotally supported in parallel to the input shaft inside the housing, and a speed-change mechanism is interposed between the input shaft and the axles. The speed-change mechanism is rotated in synchronism with the axles with a certain speed ratio thereto, is disposed above the axles, and includes at least one rotary shaft projecting outward on a side opposite to a side where the input shaft projects in the housing. A power take-off casing is disposed on the same side as the outer end of the rotary shaft in the housing and is adapted to accommodate the outer end of the rotary shaft therein. A power take-off shaft is pivotally supported in a substantially horizontal fashion in a direction perpendicular to the axles inside the power taking-out casing and is operatively interlocked with the rotary shaft.

A gate array LSI having functional blocks formed by interconnecting a plurality of basic cells arranged on a semiconductor substrate in matrix form and either signal conductive patterns or first power conductive patterns. According to the gate array LSI, the first power conductive patterns are disposed on the plurality of basic cells arranged in line and are divided and disposed on the basic cells so as to interpose the signal conductive pattern therebetween. It is therefore possible to improve the efficiency of wiring macrocells.

A control system for brushless DC motors detects counter electromotive force voltages induced in motor windings and produces rotor position detection signals from the counter electromotive force voltages. The maximum value of an input DC current to a motor drive circuit is held and the phase of the rotor position detection signals is changed in accordance with the held value of the input DC current to prevent the phase of the position detection signals from varying with the load on the brushless DC motor.

An automatic exposure control camera is of a type capable of controlling both the camera exposure and the flash light amount to be emitted by an electronic flash device. The automatic exposure control camera includes an average light measuring device for measuring an amount of the entire light impinging on an image forming plane and for producing an average signal representing the average light amount, and a spot light measuring device for measuring an amount of light impinging on a spot of the image forming plane and for producing a spot signal representing the light amount at the spot. When taking a photograph with the aid of flash light from a flash device, the amount of light impinging on the film surface is measured and integrated in real time using the average signal, and when the integrated amount reaches a predetermined level, the flash device is controlled so as to stop the emission of flash light, thereby photographing the object with an appropriate light amount even when the object is located at a corner of the frame.

A dynamic bandwidth allocation apparatus 12 of the present invention is mounted on, for example, an optical line terminal 1 in a PON system that relays upstream frames F1 and F2 received from optical network units 2, to upper networks 6. The dynamic bandwidth allocation apparatus 12 calculates, based on the reception rates of the upstream frames F1 and F2 from the optical network units 2, the sending rates of relay destinations of the upstream frames F1 and F2, and changes in the amounts of data occurring upon relaying the upstream frames F1 and F2, allocated bandwidth upper limits (max_bw) at which even when the amounts of data increase, the upstream frames F1 and F2 can be relayed; and dynamically allocates amounts of upstream transmission for the respective optical network units 2 in the range of the calculated allocated bandwidth upper limits (max_bw).
