Title: Door hanger for elevator
Inventor: OKAKATA HIROFUMI
IPC: B66B13/30
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To stably maintain a cleaning effect on a door rail for many hours by contacting/separating a cleaning roller with/from the door rail, arranging a hanger roller side gear on a hanger roller, and arranging a cleaning roller side gear meshing with the hanger roller side gear at cleaning time, on the cleaning roller. SOLUTION: At cleaning time of a door rail 1, a cleaning brush fastens a nut by moving a cleaning roller 13 to a position contacting with an upper surface of the door rail 1. Therefore, a cleaning roller side gear 13b meshes with a hanger roller side gear 12a, and when a hanger roller 12 rotates by opening/closing of a door, since the cleaning roller 13 rotates in the inverse direction of the hanger roller 12, an upper surface 1a of the door rail 1 is cleaned by the cleaning brush. When cleaning is not performed, the cleaning brush separates from the upper surface of the door rail 1 to fasten a nut by moving the cleaning roller 13 to a position where the cleaning roller side gear 13b does not mesh with the hanger roller side gear 12a. Therefore, abrasion and deformation of the cleaning brush can be prevented.

Title: Method of liquefying hydrogen
Inventor: HIGO MORINAGA
IPC: F25J1/00
Filed: 1988-12-24
Abstract: PURPOSE:To efficiently obtain the supercooled liquefied hydrogen with a simple and minimal equipment by maintaining the state of hydrogen within the temperature and pressure ranges of its liquid phase during the processes subsequent to the Joule- Thompson expansion after the final ortho-para conversion. CONSTITUTION:The material hydrogen GH2 from the tube 1 is compressed by a compressor 2 and is cooled by being routed through heat exchangers 4, 5, 6, 7. The pressurized and cooled hydrogen expands in a first expansion valve 16 to be decompressed down to about 4.1atg to become liquid hydrogen at about -247 deg.C, which is introduced to the final stage heat exchanger 17 where it exchanges heat with the counterflowing helium at -254 deg.C to be cooled down to -253 deg.C. It then expands in a second expansion valve 18 to become the liquid hydrogen at 0.2atg at about -253 deg.C. The pressure after the expansion in the first expansion valve 16 does not allow a double-phased flow, and the temperature will be lower than the boiling temperature under the existing pressure. Even if the cold end at the final stage heat exchanger 17 is not extremely low, the pressure will be 4 to 6atg under which a flash loss will not be caused when expanded in the second expansion valve 18 to the reservoir pressure. The resultant liquid hydrogen is delivered through a tube 19 to the reservoir for storage.

IPC: H01L21/302
Filed: 1988-12-23
Abstract: PURPOSE:To prevent the production of etching reduce from occurring by a method wherein the heating of etching underneath material is started at specified time near the termination of etching process of any material to be etched. CONSTITUTION:The heating of an etching underneath material (equivalent to a substrate) 10 is started at the time slightly before the termination of etching process. Accordingly, any surface adsorption materials 13 going to bond onto the etching underneath material 10 are liberated from the material 10 by thermal energy and decreased not to cause the polymerization reaction despite the existance of any incident ion seed 12. Through these procedures, any polymer production can be prevented from occurring without affecting the etching shape at all to enhance the reliability upon process.

Title: Information communication system
Inventor: MAKINO IKUFUMI
IPC: H04L12/40
Filed: 1988-12-23
Abstract: PURPOSE:To improve the transmission efficiency of information by setting a wait time till a connection request signal to a master station is sent after a slave station confirms an idle communication line within a range of a time at random. CONSTITUTION:After communication 11 is finished and an idle communication line 6 is confirmed, connection request signals 12-14 are sent from slave stations 2, 3, 4 to a master station 1. The wait time till the signals 12-14 is outputted is set at random to be connection request wait times 16-18, In this case, since the signal 12 of the slave station 2 is sent earliest, the connection is applied without contention with a connection request of other station and after a predetermined connection processing time 19 elapses, the communication 15 between the slave station 2 and the master station 1 is implemented. Thus, the contention is reduced to improve the information transmission efficiency by setting the wait time from the confirmation of an idle communication line 6 by the slave stations 2-5 till the connection request signal is sent to the master station 1 within a time range at random.

Filed: 1989-12-15
Abstract: PURPOSE:To eliminate need of pulling/inserting a terminal resistance manually by opening a contact by an insulation plate at the time of inserting a male connector, and closing the contact at the time of removing the male connector. CONSTITUTION:A terminal resistance 5 is connected with a signal line 6 connected with a female connector 2 through a contact 4, and a freely movable insulation plate 3 is provided in the inserting/removing direction of a male connector 1 provided to the female connector 2. At the time of inserting the male connector 1, the contact 4 is opened by this insulation plate 3, and the contact 4 is closed at the time of removing the male connector 1. A terminal resistance 5 is thus separated from a signal line 6 when the male connector 1 is inserted to the female connector 2, while the terminal resistance 5 is connected with the signal line 6 when the male connector 1 is not inserted into the female connector 2. If it is the terminal or not is thus determined, and if it is the terminal, the terminal resistance can automatically be connected.
