  • Publication number: 20240132147
    Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

  • Patent number: 11919579
    Abstract: A power supply system includes a system control unit, an auxiliary power supply, and an auxiliary-power-supply control unit. The system control unit and the auxiliary-power-supply control unit are configured such that information of at least one control unit of the system control unit and the auxiliary-power-supply control unit is able to be output to another control unit of the system control unit and the auxiliary-power-supply control unit. The at least one control unit is configured to output information indicating that an operation of the at least one control unit is stopped to the other control unit when the at least one control unit stops the operation of the at least one control unit.

  • Publication number: 20190118991
    Abstract: A liquid condiment container includes a bottle and a cap. A liquid condiment for the container has a viscosity from 5 to 500 Pa·s, and the container has an initial volume of 100 to 700 cm3. The body has a flat shape in horizontal transverse section in an erect state with a short axis Q and a long axis R that are orthogonal to a center axis X. The bottle has an inner pressure of ?1.0 to ?3.0 kPa after 30 seconds of sucking air from the bottle, the air being sucked by 10% of the initial volume from when the bottle is completely filled air. The bottle is flexibly deformed to easily discharge its content even when the content is a high-viscosity liquid condiment, and the original aesthetic appearance of the container is unlikely to be impaired even when the content is reduced.

  • Publication number: 20080023495
    Abstract: A dispensing gun discharges a viscous liquid material through a plurality of discharge openings in equal amounts simultaneously. A dividing member divides a passage for the viscous liquid material into a first holding chamber and a second holding chamber and has a communicating opening preferably aligned with the axis of the passage. A flow of the viscous liquid material squeezed from a pouch and deviated from the axis of the passage is held temporarily in the first holding chamber and is forced through a communication opening into the second holding chamber along the axis of the passage. And the viscous liquid material held in the second holding chamber is distributed evenly to the discharge openings.

  • Patent number: 6917804
    Abstract: All access points are operated synchronously, and monitor the beacon to mate with the hopping frequency of the neighboring access point. Accordingly, the station can grasp the up-to-date radio situation of the neighboring access point to be entered subsequently, and constructs the information as the database. As a result, when the beacon quality of the current subscription (connected) access point is reduced lower than the threshold value, the hopping channel and the hopping pattern are fitted to the neighboring access point having the best communication environment by referring the database, and then the subscription operation is applied directly.

  • Publication number: 20020002805
    Abstract: A bonding member 1 comprising a metallic plate 2 formed as a small piece onto which a hot melt adhesive layer 3 is formed at least one side of said metallic plate 2, and a gypsum board mounting method for mounting a gypsum board 5 using the bonding member 1, comprising: fixing said bonding member 5 temporarily; pushing said gypsum board 5, heating the metallic plate 2 with electromagnetic induction to melt said hot melt adhesive layer 3; and thereby allowing the gypsum board 5 to be bonded easily without noise. The bonded gypsum board 5 can be recycled because it can be peeled off easily with melting the adhesive layer 3 without damage of the board.

  • Patent number: 5235422
    Abstract: A synchronizing clock generating circuit for generating synchronizing clocks timed to synchronizing signals contained in input video signals is disclosed. A trapezoidal wave from a trapezoidal wave generator 19 and a reference pulse RP from a reference pulse generator 12 are compared as to phase in a phase comparator 21, while the trapezoidal wave and a pseudo-reference pulse rp from a CH2 generator 23 are compared as to phase in a phase comparator 22, and a difference between outputs of phase comparison is used in a dc detection circuit 24 for controlling the gradient of the trapezoidal wave. Besides, an output of a VCO 15, controlled by the results of phase comparison between the trapezoidal wave and the reference pulse RP is used as a synchronizing clock signal.

  • Patent number: 4445092
    Abstract: A periodic pulse forming circuit, for example, for use in a video tape recording and reproducing apparatus or VTR, for distinguishing valid horizontal sync signals from noise signals in a separated horizontal sync signal train from a reproduced video signal includes a saw-tooth generator and a sample and hold circuit to produce a signal representing the interval between successive sync or noise pulses. Each sample from the sample and hold circuit is compared by a window comparator with a signal representing the average interval between successive pulses to establish whether the interval between successive pulses is within a predetermined range. If it is, the second pulse is passed by a gate but if it is not, the pulse is blocked. The noise pulse signals are thus removed. The circuit allows the reliable elimination of noise pulses even where the tape replay rate is varied for fast and slow motion reproduction.

  • Patent number: 3945551
    Abstract: A pneumatically operated nailing machine for driving nails by a main piston operated by compressed air. A nail feeding piston is actuated by compressed air, synchronous with the movement of the main piston. To make the feeding of nails smooth, a device to accelerate evacuation of compressed air from the nail feeding piston is attached and the nail feeding piston is resiliently engaged with a nail feeding pawl. The front end of the nail feeding pawl is provided with a cutting edge for cutting a steel wire connecting the nails. A nail magazine is provided with a flat nail placing plate so that the nails are always fed to a fixed position, and against which each of the contained nails is resiliently pressed. The fitting position of the nail placing plate is changeable to permit the use of nails of different lengths.
