Abstract: A method of producing a lightweight building material, such as an aggregate, comprises mixing clay powder with a high percentage of coal dust to create areas of coal within the mixture which represent a desired density of voids, pelletising the mixture in the case of aggregate, and firing it to burn off the coal and harden the clay. The burning off of the coal leaves lightweight void areas within the hardened clay to form a lightweight building material or aggregate.

Abstract: In an image forming apparatus including a developing unit and a photoconductive dram, employing a toner sensor disposed at a toner mixing portion of the developing unit having a mixing member to be turned for mixing and frictionally charging the toner, a detection of the residual quantity or density of the toner according to an output voltage of the sensor is carried out. To detect the residual quantity or density of the toner, sampling of an output voltage of the toner sensor is executed by predetermined times during a predetermined period with the mixing member being turned at a specific constant speed, and averaging the sampled values. As a result, correct data for the residual quantity or density of the toner can be obtained.

Abstract: The invention relates to a procedure used in an elevator, whereby the brightness and sound volume of the signalling of the signal devices are controlled on the basis of the background illuminance and the noise in the environment. The intensities of the background noise and illuminance are measured before the signalling and the values obtained are compared with given reference values (12 and 13). Based on these, the brightness and sound volume of the signalling are adjusted to suitable values by volume and brightness control units (4,5; 6,7).

Abstract: A method for patterning precursor film, and products thereof. The method for patterning precursor film includes the steps of depositing a blocking layer over the precursor film, patterning the overlaid blocking layer to uncover portions of the precursor film, irradiating the patterned blocking layer and uncovered portions of the precursor film with a beam sufficiently energetic to radiation modify the full thickness of unmasked portions of the precursor film and insufficiently energetic to radiation modify portions of the precursor film covered by the blocking layer, and developing the precursor film. The blocking layer has a lesser thickness than the precursor film, but is sufficiently thick to block an irradiating beam having the minimal energy necessary to radiation modify the full thickness of the precursor layer.

Abstract: An AF station can be reliably identified even if a poor reception condition occurs temporarily, while suppressing unnecessary searches. In searching an AF station by using a PI code and an AF code, it is judged whether an AF station has a different PI code or whether the PI code of an AF station cannot be identified in a predetermined time period. Such an AF station is preferentially searched a predetermined number of times. If the same AF station remains under one of such conditions a predetermined number of times, then searching this AF station is reserved for a predetermined time period.

The solder tails of the terminals are configured for receiving the circuit board at a first angular orientation wherein minimal contact force is effected between the solder tails and the contact pads to prevent any substantial wiping away of the solder paste from the contact pads and a second angular orientation wherein substantial contact force is effected between the solder tails and the contact pads in a direction generally normal to the faces of the circuit board. Therefore, the solder paste remains in an interface area at each contact pad and its respective solder tail.

Abstract: A cable management system provides routing of wired services between service lines (16) and user lines (18). Each service line enters the cable system at a service termination unit circuit card (22) which also holds a portion of a crosspoint switch matrix (126). Each user line enters the system at a line termination unit circuit card (20). The service termination unit circuit cards are all mounted to connectors (36) on a first side of a centerplane board (24) and the line termination unit circuit cards are mounted to connectors (36) on the other side of the centerplane board. Pins (37) extending through the centerplane board (24) interconnect the connectors so that any service line can be connected to any user line. A system controller card (26) mounted to the centerplane board communicates with the circuit cards via a bus on the centerplane board (24). Each of the service and line termination unit circuit cards (20) is provided with a unique identification code corresponding to the connector (36) in which it is installed, in addition to "as built" information characterizing the card (20). The controller card (26) polls all the service and line termination unit circuit cards (20) to generate a "map" of all the "assets" of the system. Further, each line termination unit circuit card (20) provides a predetermined voltaae to all of the service termination unit circuit cards (20). The service termination unit circuit cards respond to the absence of that predetermined voltage from a connector (36) on the second side of the centerplane board (24) by opening all connections to that connector (36).
