摘要： A loudspeaker includes a bobbin, a coil, a magnetic circuit having a magnetic gap, a first cylinder fixed to the outer surface of the bobbin, a second cylinder connected with the first cylinder, a diaphragm and a damper coupled to the outer circumferential surface of the second cylinder, an edge coupled to the diaphragm, a frame, and terminals. The outer circumference of a yoke constituting the magnetic circuit has a plurality of slits, while the first cylinder and the second cylinder are connected together by a plurality of radially-disposed joints. The loudspeaker has a flat profile yet is compatible with large amplitude and high output power, and capable of reproducing a wide range of sounds from a low tone to a high tone.

摘要： A headphone is designed to have two resonant peaks for simulating loudspeaker reproduction. The headphone comprises a housing in which an electroacoustic transducer with a diaphragm is positioned, wherein the housing is formed with a rearward cavity positioned adjacent to the diaphragm remote from the listener's ear to provide an acoustic compliance to the generated acoustic energy. In order to generate the two resonant peaks to simulate a sensation of realism as if the listener is hearing sound from a loudspeaker, the rearward cavity is communicated with the atmosphere through apertures. The acoustic compliance of the rearward cavity coacts with the apertures to produce two resonant peaks at frequencies corresponding to the frequencies of the peaks which occur in a signal from the loudspeaker.

摘要： A piston rod is supported free to slide without using a guide bush so that there is no risk of the guide bush falling out. Also, costs are reduced and oil leakage is prevented by eliminating additional procedures such as caulking. The piston rod, which has excellent durability, is allowed to slide smoothly over a long period of time without generating noise. For this purpose, in a bearing unit for a single cylinder type hydraulic damper or gas spring, or a multi-cylinder type hydraulic damper comprising seal members 55, 56, 57 and 64, and a rod guide 6, the rod guide 6 comprises a cylindrical engaging part 13 which engages with a cylinder 2, a cylindrical bearing part 16 which guides a piston rod 5, and a bearing layer 15 fixed to the inner circumferential surface of the cylindrical bearing which slides on the outer surface of the piston rod. The bearing layer is previously fixed only at a position of a base material comprising a thin steel plate which becomes the cylindrical bearing part, and the rod guide is formed in a one-piece construction by press-molding or deep-drawing this base material.

摘要： A heating cooking apparatus utilizes a sensor of the type used in a conventional heating cooking apparatus. The change in the resistance of the sensor due to a temperature change is converted to a level representing the corresponding voltage change and this sensor level is utilized along with a level corresponding to a preset temperature of a temperature control level so selected that heat sources is turned on when the sensor level is less than this level and the heat sources is turned off when this level is exceeded so as to eliminate the occurrence of any overshooting irrespective of the presence or absence of preheating, that is, at various starting temperatures as well as in various operating conditions including one where a door is opened during the cooking and another where the cooking is interrupted due to an erroneous operation, thereby ensuring the best cooking result.
