摘要: A heat radiator for dissipating heat from an electronic device, which is mounted on a board or which is installed in a casing, to the outside thereof is basically composed of a substrate having plenty of through holes, which are produced by press molding and sintering. The substrate having a low thermal expansion coefficient is made of a copper-tungsten alloy or a copper-molybdenum alloy in which the copper content is smaller than the tungsten content or molybdenum content. The through holes each having a circular shape or a rectangular shape are infiltrated with the compound having a high thermal conductivity and composed of a copper-tungsten alloy or a copper-molybdenum alloy in which the copper content is greater than the tungsten content or molybdenum content. Thus, the heat radiator allows thermal conduction along axial directions of the through holes while substantially avoiding unwanted thermal expansion thereof.

摘要: A speaker diaphragm has a laminated construction in which a core layer is made of a porous diamond type wafer or wafers and sandwiched by a pair of surface layers made of diamond type material. Presence of numerous small pores in the core layer reduces the specific gravity of the entire diaphragm, thereby increasing efficiency in acoustic conversion. The porous construction of the core layer reduces internal loss of the diaphragm, and suppresses resonance in the treble range.

摘要: In construction of a magnetic encoder used for detection of displacement of a mobile body, a circular magnetized pattern is formed on one longitudinal end face of a magnetic rotary spindle mechanically coupled to the mobile body, and a magnetic sensor faces the magnetized pattern with a prescribed gap. Direct formation of the magnetized pattern on the rotary spindle excludes production errors caused by the conventional coupling process and end-face magnetization assures significant compactness of the entire construction.

摘要: A rotary encoder which serves to generate absolute position data is outfitted with a power source monitor which generates, during a power interruption, an alarm signal which invalidates all subsequent absolute position data being outputted by the rotary encoder. Loss of output data from the rotary encoder is reliably prevented, even upon the unexpected occurrence of very short power supply interruptions. This enhances the operational reliability and stability of the encoder considerably.

摘要: A magnetic-resistor sensor is provided with two or more comb-like patterns of different pitches formed on a single base plate and each comb-like pattern is adapted for use in combination with a magnetic scale of a corresponding information pitch so that one magnetic-resistor sensor could span magnetic scales of different information pitches. Such a universal magnetic-resistor sensor is used for a magnetic encoder having a magnetic scale in which a magnetic information pattern and a reference position pattern are formed in the same single track, thereby conserving space on the magnetic scale.
