Title: Tape cassette provided with tape reel stopper
Inventor: HASEGAWA AKIHIKO
IPC: G11B23/087
Filed: 1985-02-28
Abstract: PURPOSE:To heighten the durability of engaging pieces by providing a thick- walled part in a body at the base of the engaging pieces connected to the body of a stopper. CONSTITUTION:The body 15 of a stopper and engaging pieces 16, 16 are formed in a body by injection molding. At this time, a resin material for forming is injected from the body 15 side to the mold and passed successively to engaging piece 16, 16 sides. Thick-walled parts 16a, 16a are formed in a body at the basal part of coupling pieces 16, 16 connected to the body 15 of the stopper. The thickness of the thick-walled parts 16a, 16a becomes gradually smaller toward click parts 18, 18. Thus, as the strength of the basal parts of the engaging pieces is improved, the parts can fully withstand pressing force applied when the tape is not used.

IPC: F15B13/01
Filed: 1979-04-05
Abstract: PURPOSE: To prevent a vibration noise when a load is reversely applied to the valve, by providing built-in minor spools and spring which give cracking pressures to said minor spools in the spool of check valves arranged at a face-to-face position to each other and allowing each of the spools in the check valves to open and close in two stages when the load is reversely applied to the check valve.  
     CONSTITUTION: In a hydraulic circuit for marine steering engines, when a load is reversely acted upon the rudder in such a condition that the spool of a solenoid valve 4 is switched to a position A to permit the pressurized oil to enter the pressure chamber of a cylinder 6a through a pilot check valve 5 moving rightward a ram 7, the check valve 5 in which a pilot spool 303 has been pressed toward right establishes a negative pressure at the side of its port P 1  and a positive pressure  at the side of its port P 2 . In consequence, the spool 303 is returned to the P 1  side  to close a check valve spool 302 by a spring 305. And if the pressure of oil from a  port C 2  to a cylinder 6b is above a cracking pressure, a minor spool 307 is opened  to prevent a rapid change of pressure at the time when a reverse load is applied.

The circuit 18 detects a maximum correlation data extract point and a 2nd maximum extract point in pairs and discriminates the maximum one extract point as a timing point and a timing clock signal is outputted to data identification sections 11, 12. Then a correction detection section 25 detects a phase shift based on a difference of two extract point pairs and a phase shifter 26 shifts the demodulation process signal for it's correction. Then the identification sections 11, 12 decodes the signal X, Y and the result is demodulated into a data string by a parallel/serial converter 14.

Abstract: PROBLEM TO BE SOLVED: To shorten a time until service personnel dispatch by instantaneously calling a person in charge, and to prevent a dispatch confirmation loss at the time of operating service personnel dispatch confirmation through off-line. SOLUTION: A dispatch request to which failure contents are attached is facsimile transmitted from a reception center 1 (3), and a facsimile equipment 2A at a service base 2 requests service personnel dispatch to a person in charge by a preliminarily registered informing means (sound, light, telephone line) (4), and the person in charge who receives the information instantaneously dispatches a service man, and operates dispatch confirmation by the facsimile equipment to the reception center 1 (5). The reception center 1 inquires whether or not the dispatch confirmation is operated to the service base 2 when the dispatch confirmation is not operated after the lapse of a specific time (6). When the dispatch confirmation is not operated by the facsimile, the reception center 1 calls the service base 2 for confirming the dispatch situation (7).
