Title: Earth leakage breaker
Inventor: TAKAHASHI YASUHIRO
IPC: H01H83/02
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To provide an earth leakage breaker which opens an opening/closing mechanism in leakage even if a power supply side of a main circuit is in an open phase by energizing a trip coil in ordinary and stopping the energization in leakage. SOLUTION: The secondary current is not output from a zero-phase current transformer 1 in ordinary and a signal is not output from the leakage detection part 2 so that a transistor(Tr) 12 is turned off. On the other hand, the output voltage of a rectifier 6 is entered in a gate so that a Tr 13 is turned on and a trip coil 3 is energized at the output voltage of the rectifier 6. When the leakage occurs, the secondary current is output from the zero-phase transformer 1, the signal from the leakage detection part 2 is entered in the gate of the Tr 12, the Tr 12 is tuned on, the resistance 14B is short-circuited, the Tr 13 is turned off, and the energization to the trip coil 3 is made to stop.  Therefore, when the power supply side of the main circuit is in an open phase, the electromagnetic force of the trip coil 3 is disappeared, the engagement of the opening/ closing mechanism of the earth leakage breaker is disengaged, and the opening/ closing contact can be opened.

Abstract: PURPOSE:To shorten the time of sterilization process by making a low pressure, high humidity steam generated as the temperature of water rises by jetting steam into the water flow out through a pipe through which saturated steam flows in and which has the sectional area as large as more than three times the sectional area of a steam flow-in pipe. CONSTITUTION:The central section of the main body 1 of a converter is provided with a steam introduction pipe 2 and also with a plurality of steam jet pipes 3 which have a plurality of steam jet openings 4 for jetting steam obliquely downwards. The converter main body 1 reduces the steam pressure by making the total sectional area of the plurality of steam jet openings larger than the sectional area of the steam introduction pipe 2. Further, a steam discharge pipe 9 which has a sectional area more than at least three times the sectional area of the steam introduction pipe 2 is provided and a safety valve 21 is installed on the discharge pipe 9. Air-water separation plates 5, 6, 7 are provided above the water level surface (a) with a suitable distance among them. Since the moisture in the saturated steam 18 falls down after its collision with the air-water separation plates 5, 6, 7, the saturated steam 18 becomes a low pressure, saturated and highly wet steam 19 which is deprived of excess liquid drops and it is take out through the steam discharge pipe 9.

Abstract: PURPOSE:To obtain superior image information by always keeping the length of an optical path from the plane of an original to a photodetecting part constant by providing a friction increasing means at the contact plane of a pulley with a wire. CONSTITUTION:The coefficient of friction on the surface of the friction increasing means 30 applied on the outer peripheral plane of the pulley 12 i.e., the contact plane with the wire 11 is increased by applying knurling working or a certain plus shot, etc. Therefore, since a frictional force between the pulley 12 and the wire 11 can be increased, no slippage or sagging of the wire 11 occurs at the time of traveling an exposing device A.

In such a way, it is possible to always keep the length of the optical path from the plane P of the original to the photodetecting part 1, and to obtain the superior image information.
