    摘要： A Head Arm Assembly includes a head slider having at least one head element, an arm member for supporting the head slider at one end section, an actuator, mounted to the other end section of the arm member for rotationally moving the arm member in a direction substantially parallel with a recording medium surface around a horizontal rotation axis of the arm member, a load generation unit for generating a load for energizing the head slider in a direction toward the recording medium surface by rotationally moving the arm member in a direction substantially orthogonal to the recording medium surface around a vertical rotation axis, and a limiter unit for restraining the arm member from rotationally moving more than a predetermined limit around the vertical rotation axis in a direction away from the recording medium surface.

    摘要： A particle sensor has a gain control and an offset voltage adjustment so as to provide a consistent sensor output indicative of the particle density in match with a predetermined relationship between the sensor output and the particle density, while compensating for background noises. The gain control and the offset voltage adjustment are realized respectively by digitally controllable variable resistor networks each having a plurality of switches. A memory module is included in the sensor to store instruction data for control of the switches and therefore responsible for the gain control and the offset voltage adjustment. In particular, the particle sensor includes a memory interface which enables the selective use of two types of memory means, one is an intelligent memory module composed of EEPROM and a microcomputer, and the other is a normal memory module consisting of EEPROM.

    摘要： A temperature compensating capacitor of monolithic or multilayered configuration comprising a dielectric ceramic body and at least two electrodes buried therein. The ceramic body is composed of a major ingredient expressed by the formula, {(Sr.sub.1-x Ca.sub.x)O}.sub.k (Ti.sub.1-y Zr.sub.y)O.sub.2, where x, k and y are numerals in the ranges of 0.005 to 0.995 inclusive, 1.00 to 1.04 inclusive, and 0.005 to 0.100 inclusive, respectively. To this major ingredient is added a minor proportion of a mixture of lithium oxide, silicon dioxide, and one or more metal oxides selected from among barium oxide, magnesium oxide, zinc oxide, strontium oxide and calcium oxide. For the fabrication of capacitors the mixture of the above major ingredient and additives in finely divided form are formed into moldings of desired shape and size, each with at least two electrodes buried therein. The moldings and electrodes are cosintered in a reductive or neutral atmosphere and then are reheated at a lower temperature in an oxidative atmosphere. the cosintering temperature can be so low that nickel or like base metal can be employed as the electrode material.
