Abstract: Provided is an exhaust gas recirculating device which can curb strange noises caused by the opening and closing of a reed valve. An EGR duct (14) has a greater volume than the prior art in order to curb resonance within the EGR passage (Eg) of the opening and closing sounds generated by the reed valve (13). Specifically, the EGR duct (14) has resonant frequency characteristics which differ from the resonance frequency of the reed valve (13), and has a shape such that strange noises generated by the reed valve (13) do not resonate within the EGR duct (14).

Abstract: A deflection yoke apparatus include a saddle-type coil bobbin, first guide grooves, second guide groove, third guide groove, and a multi-wire conductor. The saddle-type coil bobbin has a front end portion and a rear end portion. The first guide grooves is formed in the inner surface of the coil bobbin and extends across the front end portion and the rear end portion. The second guide groove is formed in the front end portion of the coil bobbin. The third guide groove is formed in the rear end portion of the coil bobbin. The multi-wire conductor is wound around the coil bobbin, the conductor being routed through the first guide groove, the second guide groove, and the third guide groove. The second guide groove and third guide groove have a width in a range of 1.0 to 1.5 times the diameter of the conductor.

Abstract: A cathode ray tube including a portion whose thickness becomes (2.78+0.0038×D)≦t1≦(3.7+0.0038×D)[mm] where D is a diagonal axis length [mm] between rectangular corner portions of an effective screen of a panel, and t1 is a thickness [mm] at positions which occupy 75% of a length of a body portion extending from a sealing surface of the body portion to a yoke portion along a tube axis direction.

Abstract: Radiating member 16 comes into contact with a flat surface of semiconductor device 15 mounted on a circuit board, thereby absorbing heat from device 15. For effective heat-transfer, radiating plate 16 should be made of materials having high thermal conductivity. Housing 18 is formed by molding and fixed with member 16. Housing 18 contains coolant passage 12, and passage 12 contains diaphragm 21. Diaphragm 21 should be made of materials having high thermal conductivity and being easy to work with, and should be processed into a shape that offers highly effective heat-exchange. Coolant passage 12 is partitioned, with diaphragm 21 and housing 18, into a fluid-flow path. A fluid absorbs heat from the semiconductor device while circulating through coolant passage 12; the heated-up fluid is sucked up by a circulating pump then led back to radiator 14 for being refreshed as coolant; and the cooled-down fluid goes out for the next round of the cooling process.

Abstract: A layer-built heat exchanger has channels formed by dividers in a first-side plate 32 and a second-side plate 33. A seal plate 3 is interposed between the first- and second-side plates. The first-side plate 32 and second-side plate 33 are positioned relative to each other such that dividers 35 of the second-side plate 33 are in line with channels 36 of the first-side plate 32, and dividers 34 of the first-side plate 32 are in line with the channels 37 of the second-side plate 33, thus preventing deformation of the seal plate 3 due to a high differential pressure between the coolants flowing through the channels of the first- and second-side plates. The corners of the first-side plate 32, second-side plate 33, and seal plate 3 are also shaped differently so that omission of one of the component plates can be easily confirmed.

Abstract: In a cathode-ray tube, in order to readily and inexpensively reduce an alternating electric field irradiated by a deflection yoke to a front of the cathode-ray tube through a funnel part and a face panel, a conductive film for forming an electric field shield is formed from a neck part to a cone part of a glass bulb and is electrically connected to another conductive film formed on a funnel body part. The deflection yoke is mounted on the conductive film via an insulation sheet interposed therebetween. The conductive film is grounded to form an equipotential surface of 0 V in front of the deflection yoke. A transparent conductive film can be also formed on the external surface of the face panel to raise the reduction of the alternating electric field.

Abstract: An in-line color cathode ray tube utilizing a finely perforated shadow mask is provided, which includes a highly evacuated envelope having an longitudinal axis and a funnel section which is closed at one end by a generally cylindrical neck section having an in-line electron gun assembly and is closed at the opposite end by a faceplate, an exposure device for forming a mosaic pattern of element color emissive phosphor dots on a screen area of the faceplate, which includes a generally elongated light source, and a slitted member adapted to be disposed between the elongated light source and the faceplate of the evacuated envelope. The slitted member has a slit-shaped light transmissive area defined therein while leaving a light intercepting area around the respective light transmissive area. The light transmissive area has a generally intermediate portion with opposite ends being displaced in a direction parallel to the longitudinal axis of the evacuated envelope.
