摘要:
A logic circuit has means for controlling an active pull-down circuit in response to a detected result of an output level detection circuit. This prevents an undershoot of the output. Accordingly, it is possible to prevent malfunctions of a logic circuit in the next stage. It also prevents a prolongation of the transition time at the time of a rise of the output potential. Moreover, it reduces the power consumption of the circuit as a whole by decreasing a wasteful current from the output transistor of the emitter-follower to the active transistor.

An optical transmission module includes a housing with a heat radiating fin and a receptacle for being connected to an external optical fiber. The module also includes a coaxial can stem for mounting an optical element and a ceramic printed circuit board. The signal transmission lines are provided on one side of the board, and heat from the coaxial can package is radiated from the radiating fin.

An improved liquid level detecting and indicating system for vehicles comprising a pair of liquid level detecting elements which are arranged in opposite positions on the detecting level of a liquid in a liquid container installed in a vehicle, whereby when each of the liquid level detecting elements sends a signal indicating that the liquid level has dropped below a reference liquid level, an indicator is brought into operation. In this way, the level of liquid can be accurately detected and indicated without being influenced by the inclination or vibration of a vehicle body.

A process for producing a prepreg and a process for producing a laminated sheet therefrom are disclosed, the process for producing a prepreg comprising impregnating a fibrous base with an impregnating resin composition essentially comprising (A.sub.1) a room temperature liquid epoxy resin, (A.sub.2) an epoxy resin curing agent, (B.sub.1) a resin containing a polymerizable unsaturated group, (B.sub.2) a room temperature liquid polymerizable vinyl monomer, and (B.sub.3) a polymerization initiator and containing no solvent other than said polymerizable vinyl monomer (B.sub.2), to obtain an impregnated base, and then removing the polymerizable vinyl monomer present in said impregnated base and converting the resin components to the B-stage. The prepreg is tack-free and soft, and the laminated sheet obtained therefrom has improved metal foil peel strength and interlaminar peel strength.

There is provided a pluggable module having grooves, on lateral faces, for latching with a cage and engaging portions for detachment, wherein the module body is detached from the cage by using a module detaching unit which is inserted along the grooves and which locks the engaging portions of the module body in the length direction. Further, there is provided a detaching jig including: latch release portions which are inserted between the pluggable module and the cage; lock portions which allow the pluggable module to be locked in the detaching direction; and a handle portion for detaching the pluggable module from the cage.
