Abstract: The information display apparatus configured to display video information of a virtual image on a reflecting surface of conveyance includes: a display configured to display the video information; and a virtual image optical system configured to display a virtual image at a front of the conveyance by reflecting light emitted from the display by means of the reflecting surface. The virtual image optical system includes a concave mirror and an optical element. The optical element is arranged between the display and the concave mirror, and is configured to correct distortion of the virtual image obtained so as to correspond to a viewpoint position of a driver on a basis of a shape of the concave mirror and a shape of the optical element. The information display apparatus further includes a virtual image double image conversion reducer configured to reduce double image conversion of the virtual image.

Abstract: The information display apparatus has a housing with an opening and a transparent cover formed on the opening, the housing includes image-light generating means configured to generate image light that displays the image information and an optical system configured to allow a driver of the vehicle to recognize image information based on the image light from the image-light generating means as a virtual image in front of the windshield. When S-polarized light on the windshield is assumed to be a first polarized wave while polarized light that orthogonally crosses the S-polarized light in a polarizing direction is assumed to be a second polarized wave, the image-light generating means is configured to generate the image light made of the first polarized wave, and a transmittance/reflectance control means blocks a part of the first polarized wave and the second polarized wave of incident external light entering the housing from the opening.

Abstract: A surface light source apparatus includes an end face for taking in light emitted from a light source and a main surface for emitting the light. The surface light source apparatus further includes a plurality of structure bodies formed on an opposed surface disposed opposite to the main surface in the surface light source apparatus, each of which has a reflecting surface facing the point light source. Each structure body has a cut-off portion which removes a portion on the reflecting surface in a longitudinal direction of the structure body and in a height direction.

Abstract: A centrifugal fan device includes a diverting member the height of which is lower than the height of an interior wall surface of a casing. The diverting member diverts the air flowing to an air outlet into a centrifugal fan side and a side wall side of the diverting member and also diverts the air flowing to the air outlet into a first cover side and a second cover side of the diverting member. As a result, the amount of air blown from the air outlet is dispersed uniformly over the entire area of the air outlet, and a deviation in the amount of air blown out of the air outlet is reduced.

Abstract: An illumination apparatus that can always take in cool air and use it for cooling and improve a heat dissipation effect of a fan. LED lamp (illumination apparatus) 100 is provided with case 110, LED 121, heat sink 130 and fan apparatus 140 that blows air over heat sink 130. Heat sink 130 is mounted with fan apparatus 140 at a decentered position, and is provided with intake ports 131 that take air into fan apparatus 140, and exhaust ports 132 that exhaust the air blown over heat sink 130 on the same plane.

Abstract: A Bowden wire is positioned at two points, that is, at a wire guide bracket and at a through-hole in a back plate between which a notch of an end edge of a plate-shaped trailing arm is interposed. A predetermined preset load is applied to and curves the Bowden wire, wherein the curved Bowden wire is pressed against and fixed to a groove-shaped recess provided in the notch of the trailing arm.

Abstract: A silencer includes a cooling fan unit that cools a component which gives off heat during operation by blowing wind to the component and that outputs signal including rotational frequency information and information about timing of initiation of one cycle of noise; a storage section that stores an opposite phase waveform for the noise given off by the cooling fan unit; and a control section that detects the signal from the cooling fan unit and that adjusts the timing of initiation of one cycle of the opposite phase waveform. The configuration obviates a necessity for a microphone used for previously storing an opposite phase waveform and complicate arithmetic processing, and hence a phase lag in the opposite phase waveform can be prevented. Accordingly, the speaker can be disposed in proximity to the cooling fan. An opposite phase waveform output from the speaker can eliminate noise given off by the cooling fan over a wide range.

Abstract: In a solder paste formed by blending an alloy powder and a flux, the alloy powder is a powder mixture formed by mixing at least one powder of a Sn—Zn based alloy and at least one powder of a Sn—Ag based alloy. The alloys powders are blended so that the composition of the powder mixture is 5-10 mass % of Zn; 0.005-1.5 mass % of Ag; optionally at least one of 0.002-1.0 mass % of Cu, 0.005-15 mass % of Bi, 0.005-15 mass % of In, and 0.005-1.0 mass % of Sb; and a remainder of Sn.

Abstract: In a centrifugal fan device, the height of a diverting member is lower than the height of an interior wall surface of a casing. The diverting member diverts, the air flowing to an air outlet, into a centrifugal fan side and a side wall side of the diverting member, and the diverting member also diverts, the air flowing to the air outlet, into a first cover side and a second cover side of the diverting member. As a result, the amount of air blown from the air outlet is dispersed uniformly over the entire area of the air outlet, thereby diminishing a deviation in the amount of air blown out of the air outlet.

Abstract: The present invention provides a Sn—Zn based lead-free solder which can prevent peeling of solder from soldered portions even after the passage of long periods after soldering of portions to be soldered made of Cu. A Sn—Zn based lead-free solder according to the present invention comprises 5-10 mass percent of Zn, a total of 0.005-1.0 mass percent of at least one substance selected from the group consisting of Au, Pt, Pd, Fe, and Sb, optionally a total of at most 15 mass percent of at least one substance selected from the group consisting of Bi and In, and a remainder of Sn. This Sn—Zn based lead-free solder can be made into a solder paste using a rosin flux containing a halide such as an amine hydrochloride as an activator.

Abstract: A small cooling fan includes a rotating fan body with a vane in a flat fan housing, and an air channel for backflow prevention. The air channel is provided outside of the vicinity of the tip of the vane of the rotating fan body, extends to an air outlet, and has an inner height larger than that of a fan chamber. This structure can prevent the backflow of the wind at the air outlet and reduce the loss of the static pressure, thereby increasing the airflow quantity in spite of the small size.
