Title: Measure in snowfall elimination on water-permeable cement concrete paved face
Inventor: TOGAWA YOSHIAKI
IPC: E01C11/26
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent the frozen condition of a pavement by using the water- permeability of a water-permeable cement concrete pavement to transmit hot air from the lower side of the pavement into the surface of warming the pavement itself and to exhaust the hot air from the surface of the pavement. SOLUTION: After a roadbed or a subbase are formed and before a water- permeable cement concrete pavement is constructed, a hot air flow path is placed on the lower side of the water-permeable cement concrete pavement, which is provided with a blowout port to blow hot gas toward the surface of the pavement. Then, the water-permeable cement concrete pavement is constructed on the flow path. Hot air blown out of the blowout port is fed from the subbase to the lower side of the pavement, filled on the lower side of the pavement and exhausted from the surface of the pavement. In this way, the frozen or snow-covered condition of the water-permeable cement concrete pavement is prevented.

Title: Protected darlington transistor device
Inventor: ANDORU PEIRU RABIINIYU
IPC: H03K17/08
Filed: 1990-02-07
Abstract: PURPOSE: To display protection effect over an operating temperature range of -40 to +125 deg.C by providing a Zener diode which is coupled between the collector of a Darlington transistor(TR) and the base of a 3rd TR. CONSTITUTION: A 1st TR 2 operates as a driver stage and a 2nd TR 4 operates as an output stage. A 3rd TR 6 performs a clamp function together with the Zener diode 8 and resistors 14 and 15 to protect Darlignton pairs 2 and 4 when a voltage spike appears at the collector C of the Darlignton TR. Since the values of the resistors 14 and 15 vary with temperature in proportion to the variation of the values of resistors 10 and 12, the 3rd TR 6 is useful for the temperature compensation to the clamp function.
