Abstract: A throttle valve device includes a shaft in a cylindrical passage, a slit passing through the shaft from one lateral side to another lateral side of the shaft, a pair of bearings on both sides of the cylindrical passage and rotatably supporting one end part and another end part of the shaft, and a circular-plate valve inserted into the slit of the shaft and rotatable to open and close the cylindrical passage. A length of the slit on the one lateral side of the shaft is, in an axial direction of the shaft, longer than a length of the slit on the other lateral side of the shaft. A round end hole is formed at an end of the slit in the one end part of the shaft on the one lateral side of the shaft.

Abstract: The food material cutter of the present invention has a feeding port for feeding a doughnut, titled plates and guiding plates for guiding the fed doughnut, and rotary blades for slicing the guided doughnut in half in the thickness direction. The link mechanism causes the tilt angles of the tilted plates to be increased due to the own weight of the doughnut, and causes the guiding plates to move by an equal distance from the center of the clearance between the respective guiding plates while matching with the thickness of the doughnut. The doughnut-is guided by the titled plates and guiding plates, and falls down to the palette in a state where it is sliced in half in the thickness direction.

Abstract: To provide a food material cutter by which any operator can easily, accurately and rapidly slice ring-shaped and disk-shaped food materials such as doughnuts and bagels in half regardless of the degree of skill of the operator. The food material cutter of the present invention comprises a feeding port for feeding a doughnut, titled plates and guiding plates for guiding the fed doughnut, and rotary blades for slicing the guided doughnut in half in the thickness direction. Also, the link mechanism causes the tilt angles of the tilted plates to be increased due to the own weight of the doughnut, and causes the guiding plates to move by an equal distance from the center of the clearance between the respective guiding plates while matching with the thickness of the doughnut. The doughnut, when fed from the feeding port, is guided by the titled plates and guiding plates, and falls down to the palette in a state where it is sliced in half in the thickness direction.

Abstract: A lamp using a discharge bulb 7 as a dipped-beam lamp LL is arranged in the middle of a triple headlight, and a lighting circuit 23 is arranged in the middle of the headlight. A cord 22 for connecting the lighting circuit 23 and the discharge bulb 7 is short, and the weight balance of the headlight as a whole is stabilized even if the lighting circuit 23 is relatively heavy. Light projected from the discharge bulb 7 expands horizontally toward the auxiliary lamp CL and the main-beam lamp HL, so that the headlight is illuminated as a whole, which in turn improves the external appearance of the headlight.

Abstract: An automobile headlamp employing a projector-type lamp having an improved outer appearance. The headlamp includes a lamp body having a front opening closed by a front lens, covering said front opening, a reflective lamp cover disposed in the lamp body, and a projector lamp unit mounted in the lamp body. The projector lamp unit has a forward end portion extending through an opening in the lamp cover, with the outer surface of the forward end portion being a reflecting surface. With this structure, the gap between the projector lamp and the periphery of the lamp cover is rendered inconspicuous, and the headlamp appears deeper and more three dimensional.
