Abstract: A multilayer circuit board having a signal and power isolation circuit, which can suppress the capacitive coupling between a chip inductor and a ground layer below the chip inductor and also suppress the characteristic impedance change occurring in a mounting pad on a microstrip line. Portions of the inner-layer ground below both the mounting pad on the microstrip line and the chip inductors connected to the mounting pad are separately removed respectively as the signal transmission characteristic compensation removal portion, which is formed by removing a portion having a predetermined area and situated immediately below the mounting pad, and the inductor characteristic compensation removal portion, which is formed by removing a mounting-surface-below portion having a predetermined area and situated immediately below the chip inductors.

A transmission system for superimposing power on a signal transmission path between a first circuit module and a second circuit module includes a first capacitor between the transmission path and a first interface IC in the first circuit module, a second capacitor between the transmission path and a second interface IC in the second circuit module, a first inductor between a first power supply circuit in the first circuit module and the transmission path, and a second inductor between a second power supply circuit in the second circuit module and the transmission path. A capacitance value of the first capacitor and a capacitance value of the second capacitor differ from each other. Inductance values of each of the first and second inductors are in a range from 20 [?H] to 50 [?H].

Abstract: An image forming apparatus includes a main CPU. The main CPU detects whether or not a commercial power supply has been shut off while operating in a warning mode which, in response to detecting an intruder, alerts a surrounding person and/or a specified person that the intruder was detected. If the commercial power supply has been shut off, the surroundings are alerted in the form of audio that the commercial power supply has been shut off, and the alert is also issued by transmission of an email addressed to an administrator.

Abstract: A common mode choke coil includes a laminated-type coil that has high breakdown voltage reliability. Coil conductors and a coil conductor for a secondary coil are laminated so as to be respectively interposed between, coil conductors for a primary coil, two coil conductors connected to each other by an inner circumferential side via hole conductor and two coil conductors connected by an inner circumferential side via hole conductor. Meanwhile, in the primary coil, an outer circumferential side via hole conductor is provided so as to pass through only one insulation layer, and accordingly, a length of the outer circumferential side via hole conductor in an axis line direction thereof is reduced. As a result, an amount of conductive material used for the outer circumferential side via hole conductor that diffuses during firing can be reduced, and a drop in a thickness of the insulation layers can be suppressed.

Abstract: A floating flap gate to prevent water from overflowing into underground spaces, with ease in raising or lowering the door body when water level changes. The floating flap gate comprises a door body with a forward end which swings upwards or downwards in a same direction following a rise or a drop in water level, wherein an opposite end serves as a fulcrum. A rod is attached to the forward end of the door body. One end of a wire rope is attached to the rod, and the other end is attached to a counterweight via fixed pulleys. The fixed pulleys are arranged so that the counterweight is at its lowest point when the angle of inclination of the door body with respect to a horizontal plane reaches within a range from 10° to 80° during raising or lowering of the door body.

Abstract: The present invention utilizes a vertically upward force of a water when a tsunami smashes into a building to close openings that exist in an elevated location such as air supply and exhaust ducts, powerlessly and without a manual operation. The present invention serves as a disaster prevention panel which closes an opening 2a disposed in a wall of a building 2. A door bumper 3 is disposed on an outer peripheral wall of the opening 2a, and side door bumpers 4 are disposed on both sides of the door bumper 3. A door body 1, which closes the opening 2a and which has a specific gravity lower than a seawater, is attached between the side door bumpers 4 on both sides so as to freely swing upwards, with a lower portion of the door bumper 3 serving as a fulcrum.

Abstract: To reduce the size, scale of construction, and running cost of an apparatus for cleaning a sand filtration layer. A cleaning system which removes clogging sediments from a sand filtration layer 2, used with an apparatus for an infiltration intake of seawater which performs a seawater intake, by means of a water intake pipe 4 buried in the supporting gravel layer 3, after the seawater has been infiltrated through the sand filtration layer 2 and a supporting gravel layer 3 on an ocean floor. This cleaning system is provided with a diffuser pipe 7 having blow holes 6, and which is buried in the supporting gravel layer 3, as well as a compressed air delivery device 8 for feeding an air into the diffuser pipe 7. The system operates by blowing the air from the blow holes 6 to agitate the filtration sand of the sand filtration layer 2, to remove the sediments which have become trapped in or accumulated on the sand filtration layer 2.

Abstract: The present invention provides a floating flap gap which has a door body with a forward end which is able to swing upwards, in a direction in which the water flows into an opening or at an access way, around a base end thereof serving as a fulcrum. The door body is attached to one end of a wire rope, and an auxiliary force generating means is attached to the other end thereof. This structure makes it possible to prevent an overflow during the initial influx of water and to enhance the ability of the door body to follow the water level when the door body begins to lower. This structure additionally makes it possible to mitigate a shock which occurs when raising of the door body is completed and when lowering of the door body is completed.
