Inventor: NOJIMA OSAMU
IPC: G08B21/00
Filed: 1994-12-22
Abstract: PURPOSE: To enable a device for warning approach of a mobile crane to power- transmission or distribution line to issue a warning when any part of a mobile crane approaches a power-transmission or distribution line by constituting the main body of the crane as a sensor and detecting an induced current flowing to the ground from the main body of the crane with an induced current detector.

Title: Method of manufacturing thin film multilayer circuit board
Inventor: TAKAHASHI YASUHITO
IPC: H05K3/46
Filed: 1991-12-19
Abstract: PURPOSE:To control the height of insulating layers at an outer peripheral strip part in correspondence with the height of the insulating layers on a main body part to flatten the insulating layers by a method wherein a special insulating layer formation mask is selectively used. CONSTITUTION:A special insulating layer formation mask 80, which is formed with a main body insulating layer formation part (y) only, is selectively used to conduct the manufacture of a multilayer board 60 at a point of time when the difference between the height(h) of insulating layers 2 on a main body part 14 and the height(H) of the insulating layers 2 at an outer peripheral strip part 13 becomes equal to the thickness of the amount of roughly one layer of the insulating layer 2, which are formed at a product manufacture area (alpha). Since the mask 80 has the formation part (y) only, the layers 2 are formed only on the main body part 14 and are not formed at the strip part 13. Fig.(b) shows a state that the insulating layer 2 of a four step is formed only on the main body part 14. As it is clear from this diagram, the height(H) of the layers 2 at the strip part 13 is roughly equal to the height(h) of the layers 2 on the main body part 14 at this point of time. Therefore, a patterning mask 30 closely adheres to the main body part 14. Accordingly, a patterning of circuit patterns 10 is performed with very high precision.
