Title: Resilient endless belt of crawler
Inventor: SAKAI KENICHI
IPC: B62D55/253
Filed: 1982-08-13
Abstract: PURPOSE:To prevent the middle part of a belt-like main body from being bent so as to avoid disengagement of wheels by embedding a laterally laid reinforcement in a thickened part in a wrapped manner. CONSTITUTION:Since an endless belt is sufficiently reinforced by forming a thickened part 12 in the middle part thereof, the belt 1 is scarcely bent. Therefore, the dimensional variation in distance between guide projections 3A and 4A and between wheels hardly occurs and an inclination angle theta is also reduced, hence preventing wheels from coming off. Furthermore, a laterally laid reinforcement 14 is embedded in the thickened part 12 just in the wrapped manner, hence perfectly preventing the belt from being bent at the middle part thereof. Since any deflection may be thus prevented and a resilient part is additionally formed between reinforcements 3 and 4, any crack can not be produced.

Title: Passage switching device
Inventor: NAKATANI MITSUO
IPC: F16K31/42
Filed: 1990-05-31
Abstract: PURPOSE:To eliminate a state that both valves are opened by providing one fluid passage and by setting the pressure in a fluid passage so that when both of the first and second valve are opened allowing fluid to pass, the force to close the diaphragm valve seat of the second valve may become larger than the force to open the diaphragm valve seat. CONSTITUTION:When an electromagnetic switch valve 38 is off, the first valve 6 is closed, and the pressure in the second upper section valve chamber 25 on the down stream side becomes low. On the other hand, since the pressure in the valve chamber 3 outside the first valve is transmitted to the valve chamber 20 outside the second valve through a hole 19, the pressure in the valve chamber 20 becomes high, and a diaphragm valve seat 24 becomes opening state at the lower side due to the pressure difference between those in the valve chamber 25 and 20. When the switch valve 38 is on, the first valve body 6 is opened, and since the second upper valve section chamber 25 is filled with fluid, the pressure in the chamber 25 becomes high, and the diaphragm valve seat 24 is shifted to closed state, and such states that the first valve 6 is opened and the second valve 24 is closed are secured. Therefore, two fluid passages can be switched by one fluid passage switching electromagnetic valve 38.

CONSTITUTION:In an electronic apparatus, a water-immersion sensing sheet 14 wherein a pair of electrodes 16, 17 is connected electrically with each other owing to a water-immersion and a fuse 19 which is cut off by the electric connection generated in the water-immersion sensing sheet 14 are provided respectively. Further, in the electronic apparatus, a battery 18 is connected with a paging circuit 20 via the fuse 19, and one terminal part 16a of the water- immersion sensing sheet 14 is connected with the connection point of the paging circuit 20 and the fuse 19, and another terminal part 17a of the water-immersion sensing sheet 14 is connected with the connection point of the paging circuit 20 and the battery 18. Therefore, when water is immersed in the case of the electronic apparatus, the electric connection of the water-immersion sensing sheet 14 is caused by the water-immersion, and thereby, the fuse 19 is cut off. Therefore, whether the water-immersion is present or not can be known based on whether the fuse 19 is cut off or not.
