  • Patent number: 12024116
    Abstract: In this buckle device, a base end portion of a belt is folded back on itself to form a ring-shaped portion, and the belt is wound onto a spool in a state in which the ring-shaped portion of the belt has been inserted through an insertion hole in the spool. This enables a winding radius of the belt to be increased by the base end portion of the belt and enables a load at which the belt is permitted to be pulled out to be reduced, when the belt is pulled out from the spool.

  • Patent number: 11987205
    Abstract: In this buckle device, when a second wind of a belt is pulled out from a spool, a load at which the belt is permitted to be pulled out is small, whereas slide resistance of the belt with respect to a slide face is large. When a first wind of the belt is then pulled out from the spool, the belt pull-out permitting load is large, whereas the slide resistance of the belt with respect to the slide face is small. This enables variation in a load at which extending of a buckle body is permitted to be suppressed.

  • Patent number: 11819092
    Abstract: In a buckle device, when a belt starts to be allowed to be drawn, a fracture portion is deformed by a side surface of a connection hole of a spool, so that the fracture portion allows a rotation of the spool and allows drawing of the belt. Then, the fracture portion is fractured by the side surface of the connection hole. Therefore, a drawing allowance load of the belt when the belt starts to be allowed to be drawn can be increased.

  • Publication number: 20230064662
    Abstract: In the buckle device, when or after torsional deformation of the torsion shaft has started and allowance of the drawing-out of the belt has started, the breaking portion of the shear plate is started to be deformed by the coupling hole side surface of the spool, whereby the breaking portion allows the rotation of the spool and allows the drawing-out of the belt. Therefore, the allowable drawing-out load of the belt can be made the sum of the load for torsionally deforming the torsion shaft and the load for deforming the breaking portion, and can be increased.

  • Patent number: 7656423
    Abstract: An imaging device stores and photoelectric-converts incoming light from an object of which an image is to be captured with a CCD, and controls an output level of a picture signal obtained by signal processing an image signal output from the CCD. An output adjustment value of the picture signal in the output control is set to become 50 to 70 IRE according to a peak value of the picture signal when a test pattern is captured under standard conditions. Accordingly, it is possible to have a typical imaging device display a captured image darker, and thus enable imaging suitable for nighttime imaging and the like.

  • Patent number: 7045759
    Abstract: A second circuit separately extracts a synchronization signal and brightness signal from an image signal output from a camera for capturing an image of a subject. A gamma amplifier produces a gamma correction signal based on a brightness ratio characteristic in which a display brightness increases as the signal level of the brightness signal increases and the display brightness is set using a display brightness correction ratio which is preferably 70 to 90% of an equi-proportional display brightness correction ratio when the signal level of the brightness signal falls in a high-brightness range. A liquid crystal display receives the gamma correction signal and displays an image captured by the camera with the display brightness set in accordance with the brightness ratio characteristic while synchronizing with a drive timing signal output from a first circuit.

  • Patent number: 6825469
    Abstract: A vehicle visibility assist device is started up when a switching operation of a switch for an external vehicle light is detected and when it is determined by a brightness sensor that it is darker outside of the vehicle than a predetermined threshold. The visibility assist device projects infrared light to a region outside the vehicle, captures a reflection of the light, processes an image of the region outside the vehicle, and projects the image onto a surface visible to the vehicle operator.

  • Patent number: 6693948
    Abstract: The present invention provides an arc-melting apparatus which attains extremely high efficiency by preheating scraps using exhaust gas from the melting chamber. The arc-melting apparatus needs for no device to carry and supply an iron source to a melting chamber, which makes it possible to preheat the next charge. The arc-melting apparatus has a melting furnace which melts scraps, a preheating shaft connected directly to an upper part of one side of the melting furnace, an arc electrode for melting scraps in the melting furnace, a bucket for supplying scraps to the preheat shaft so as to continuously maintain scraps in the melting furnace and in the preheating shaft, a tapping portion having a tapping hole, being projected outward from the melting furnace and a tilting device for tilting the melting furnace on a side of the tapping portion. The tapping portion is arranged at an orthogonal direction to the direction of the supplied cold iron source.
