Title: Structure of fire hydrant
Inventor: MASUTANI SHIGEKI
IPC: F16K27/06
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To prevent abrupt injection of water so as to conduct an inspection of an operation condition of a fire hydrant easily by providing a contact part which comes into contact with the water jetting from an opening formed by exposing inner bore passing through a valve element substantially like a ball slightly and reduces force of water in the vicinity of the opening. SOLUTION: When a cap of a fire hydrant is rotated and a valve element 3 turns in the counterclockwise direction, an outer face of the valve element 3 and a valve seat 8a adhere closely and mutually, and inner bore 3a is also shut off. When this valve element 3 is turned by an angle α only and an end fringe of the outer face of the valve element 3 leaves the valve seat 8a on an upper side, the inner bore 3a of the valve element 3 is partially exposed to form an opening 13 like a narrow slit. At this time, the strongly energized water jets from the opening 13 toward an upper end of a mouthpiece 11. The water comes into contact with a contact part 10d extended from a lower end of a mouthpiece receiver 10 in the vicinity of the opening 13, and a force of the water is reduced.  When a degree of opening of the valve element 3 is increased furthermore, the effect of the contact part 10d is reduced, and the water jets without reducing its force.

Title: Information recording and reproducing device
Inventor: WATABE TETSUO
IPC: G06K13/06
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent cards from being dually inserted by recognizing card insertion before a user inserts a card. SOLUTION: When the loading of a card C to a mounting table 10 is completed, the flat part of a cam roller 11 becomes horizontal to the card C and the shielding part 25b of a sliding member 25 closes an opening part 13 into which the card C is inserted completely. Even though the table 10 is made to move in the direction orthogonally crossing a card information track along guiding shafts 17 and 18 to be shifted to a prescribed recording and reproduction operation when a command for recording and reproduction comes from a host controlling system of the device, another card C can not be inserted because the part 13 is closed by the part 25b even if a user tries to insert the card C from the outside in this case.
