Title: Installation method of protection plate for thrusting pipe and thrusting pipe with protection pipe
Inventor: NISHIURA KATSUTOSHI
IPC: F16L1/024
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To give a protection function from other construction works to thrust pipes directly pushed in the ground in the pipe jacking method to improve the safety. SOLUTION: Protection iron plates 13 are stuck on the surface of the superficial layer 12 such as mortar covering the periphery of a conduit 11 in a thrusting pipe 10 with protection iron plates embedded in the ground by the pipe jacking method. Projections 14 are formed at every distance at the inside face of the protection iron plate 13 so that the projections are caught by the superficial layer 12 and the adhesive force is mechanically increased when the iron plate is attached to the surface. The protection iron plate 13 is provided with an endurable hardness against the cutter bit of boring. When the thrusting pipe 10 with protection iron plates is pushed in the ground, since the adhesive force between the protection iron pipes and the surface layer is increased, the protection iron plates 13 are prevented from peeling off or dropping out during the jacking work.

Title: Surface grinding machine
Inventor: SANO TAKASHI
IPC: B23Q3/154
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To provide a ground surface excellent in flatness by forming a table, on which a workpiece is placed, of a surface plate having a magnetic pole built therein through a nonmagnetic separator and a case having therein an iron core and a coil. SOLUTION: At the time of machining operation, current is supplied to a coil 16 to form N and S poles alternately in adjacent magnetic poles 13 to thereby a workpiece is attracted onto an upper surface of a surface plate 10. A case 30 and a grinding wheel are moved relatively to perform surface grinding on the upper surface of the workpiece. During the operation, heat generating from the coil 16 is transmitted to the case 30, but since the case 30 has a large heat capacity and high rigidity the case 30 does not deform substantially. As a result, no deformation generates on the surface plate 10 so that a ground surface excellent in flatness is provided.

Title: Power distribution system operating unit
Inventor: OIDA KOICHI
IPC: H02H7/26
Filed: 1995-02-22
Abstract: PURPOSE: To surely detect a power failure by instructing the operation of switches by using a remote supervisory master-station device and subordinate-station device in accordance with a switch operating procedure for circulating electric power to a sound interrupted section on the load side from a disconnected section. CONSTITUTION: When an instantaneous ground failure occurs due to disconnection, the breaking and reclosing operations of a circuit breaker 1 are inputted to an arithmetic device 13 through an information transmitter 18 and the operation of a disconnection detecting relay and opening/ closing states of switches are also inputted to the device 13 through a TC subordinate-station device 15 and mater-station device 12 and a disconnected section discriminating means 13A discriminates a disconnected section based on the information. When the power source-side section of a switch SW2 is discriminated as the disconnected section, a power circulating switch operating procedure preparing means 13C prepares a switch operating procedure for circulating electric power to the section after the switch SW2 and performs power circulating calculation.  Then a disconnected section cutoff switch operating procedure preparing means 13B cuts off the disconnected section and prepares the opening procedure of the switch which is nearest to the power source and a switching operation instructing means 13D outputs an operation executing instruction to the TC master-station device 12. Therefore, the disconnected section can be detected exactly.

Filed: 1989-03-09
Abstract: PURPOSE:To obtain a laminated sheet having temp. control function positively absorbing the sunlight only at a necessary time and suppressing the absorption of the sunlight at a time reaching predetermined temp. or higher by containing heat-sensitive reversibly color-changeable ink showing a dark color at temp. lower than definite temp. and a light color at temp. higher than said definite temp. in a coating film. CONSTITUTION:As the material of a synthetic resin sheet, there is no special limit and polyester, polyolefin, polyamide, polyvinyl acetate, polyvinyl chloride, polyvinylidene chloride, polyurethane and acrylic resin are designated. A laminated sheet must contains heat sensitive reversively color-changeable ink showing a dark color at temp. higher than definite temp. and a light color at temp. higher than said definite temp. in the coating film and/or coating intermediate layer thereof. Herein, the dark color means a color having high visible high absorbing effect and, for example, black, dark gray, dark blue, blue, red and dark green are designated. The light color means a color having low visible light absorbing effect and, for example, white, beige and cream are designated. By this constitution, light absorbing efficiency can be enhanced at temp. lower than the definite temp. and, contrarily, light absorbing efficiency can be lowered at temp. higher than the definite temp. In other words, temp. control function can be imparted corresponding to environmental temp.

Title: Motor controlling circuit for two-storied parking equipment
Inventor: INUKAI SHINPEI
IPC: H02P23/24
Filed: 1990-03-08
Abstract: PURPOSE:To simplify a circuit by connecting a first electrical contact and a second electrical contact respectively to the control circuit in series, and by using the intermittent time of the first electrical contact and the second electrical contact, to delay the reverse rotation of a motor. CONSTITUTION:When a pallet 2 is moved upward, then a stop switch ST is pushed and the pallet is stopped and immediately after that, when a descending switch DW is pushed and the pallet is moved down, then a motor M is reversely rotated. After that, a stopper 32 starts moving rotationally from a dropping- proof position A and a limit switch LSZ1(a first electrical contact) is turned OFF and after that, the stopper 32 approaches a pallet descending position B. Then, t1 hours are needed till a limit switch LSZ2(a second electrical contact) is turned ON, and so counter-electromotive current to be generated at the time of the reverse rotation of the motor M is prevented from being generated. As a result, by composing a control circuit mechanically, it can be simplified.

The stored information is rewritten to other existence area information ''0'', when the vehicle runs along a prescribed path and approaches a garage being a functionally different existence area, and communication is made to a vehicle advancing direction discriminating device provided in the vicinity of an entrance of the garage, and the vehicle goes into the garage in a state that said information is stored in the on-vehicle machine. When this vehicle goes out of the garage, and communicates again with the on-road machine on the path, a state information becomes ''1'' signifying that the vehicle is running again. In this way, the running vehicle itself holds information which is capable of discriminating the running state.
