The red phosphor includes a Mn-activated complex fluoride represented by the following general formula (1) and bismuth: A2MF6:Mn4+??(1) wherein A represents at least one alkali metal element selected from the group consisting of lithium, sodium, potassium, rubidium and cesium, and M represents at least one tetravalent element selected from the group consisting of silicon, germanium, tin, titanium, zirconium and hafnium.

Abstract: Construction is achieved in which a steering column 4b and a support bracket 17b are able to smoothly displace in the forward direction during a secondary collision. Spring-side locking sections 40 of a bias spring 32a engage with locking tabs 41 of the support bracket 17b in a state so as to press downward on the locking tabs 41. A pressure section 35a of the bias spring 32a engages with a receiving surface of the steering column 4b in a state so as to cause an upward pressure force to act on the steering column 4b.

Abstract: A steering device is provided that facilitates an operation of mounting a friction plate on a mounting bracket. A first friction plate and a second friction plate just need to be mounted on an outer column only. It is possible to greatly facilitate an operation of assembling alternate layers of the first friction plate and the second friction plate at specified orientations. When the outer column is displaced telescopically, a tightening rod touches a long slit in the second friction plate. The second friction plate rocks around a columnar protrusion as the rocking center. The long slit is formed lengthwise in a direction of tilt positioning. The long slit absorbs a difference between a rocking trajectory formed by the second friction plate and a linear trajectory formed by the outer column. The second friction plate smoothly rocks. The outer column can be smoothly adjusted in the telescopic direction.

Abstract: Construction of a steering column support apparatus is achieved that is able to suppress an increase in the height dimension, maintain a function of the steering column 6a being able to displace smoothly in the forward direction during a secondary collision and prevent the steering column from dropping down even when the steering column 6a is displaced in the forward direction due to a secondary collision. The steering column support apparatus comprises a non-dropping bracket 45 that is fastened to the vehicle body, a dropping bracket 46 that is supported by the steering column 6a, a pair of bolts 47 and a pair of support capsules 16a. During a secondary collision, the supporting force of the support capsules 16a for supporting the non-dropping bracket 45 is lost and the steering column 6a displaces in the forward direction together with the bolts 47, support capsules 16a and dropping bracket 46, however, does not drop from the non-dropping bracket.

Abstract: A multi-phase oscillator includes a plurality of ring oscillators (21) each having a plurality of output ports and each formed by connecting an odd number of inverters (20) in a ring, and a plurality of resistance elements (30) coupling the output ports between the plurality of ring oscillators (21) so that all of the plurality of ring oscillators (21) operate at an identical frequency while keeping a desired phase relationship. The number of the ring oscillators (21) is not limited to an odd number but may be an even number. The multi-phase oscillator changes the state of a succeeding node of a phase coupling to accord with the state of a preceding node of the phase coupling by using the resistance elements (30) as phase coupling devices. If resistors are used as the resistance elements (30), the phase output accuracy greatly improves and high frequency oscillation is possible.

Abstract: A semiconductor integrated circuit having jitter measuring function includes a slicer (11), a T/V converter (12), an A/D converter (13), a processor (14), a multiplexer (15), and a correction section (16). The slicer (11) binarizes an input signal to generate a data signal. The T/V converter (12) outputs a voltage corresponding to the data length of an input signal. The multiplexer (15) selects the data signal or a reference signal as the input signal to the T/V converter (12). The A/D converter (13) converts the output voltage of the TN converter (12) to digital data. The processor (14) measures jitter in the input signal to the T/V converter (12) in accordance with the digital data. The correction section (16) compares the output voltage of the T/V converter (12) produced where the reference signal has been selected by the multiplexer (15) with a predetermined voltage, and corrects the output characteristics of the T/V converter (12) according to the comparison results.

Abstract: A cylinder head construction for an overhead cam type internal combustion engine using rocker arms for actuating the valves from the camshaft. A plurality of bearing portions or supports are spaced along the head and rotatably support the camshaft. A continuous rocker arm shaft extends from one end of the head to the other and is bolted to each of the bearing portions to reinforce the head and specifically the bearing portions.

Abstract: In an internal combustion engine, an intake manifold has a main distributing chamber and an auxiliary distributing chamber disposed to overlap with the main distributing chamber at a location inward thereof. The main distributing chamber is divided by a partition wall into a primary distributing chamber and a secondary distributing chamber. The partition wall has a boss through which is formed an intake guide passage having one end opening in the auxiliary distributing chamber and directed toward a substantially central location of the chamber. The primary distributing chamber, the secondary distributing chamber and the intake guide passage leading to the auxiliary distributing chamber have respective mixture-inlet ports opening in a carburetor-mounting surface formed on the outer surface of the intake manifold and arranged thereon in a compact array. Thus, the intake guide passage has a simplified configuration, and also the intake manifold can have a compact size.
