摘要： A method is provided for manufacturing a magnetic head for recording information on a magnetic recording medium in the form of a direction of magnetization, which enables manufacture of a magnetic head with gaps between turns of a conductive material constituting a coil being filled with an insulating material without any void and heat generation in the coil being suppressed. A photoresist with a higher flowability than an insulating material containing a metal element is applied to the coil. A part of the photoresist applied to the coil which covers the conductive material constituting the coil is removed by exposure and development, and on the conductive material, an insulating metal compound layer made of an insulating material containing a metal element and having a higher thermal conductivity than the photoresist is formed and polished for flattening.

摘要： A thin film magnetic head includes an upper magnetic pole maintaining a constant thickness in a range determined by the so-called gap depth. A thinner film portion is defined in the upper magnetic pole in a range rearward of the range determined by the gap depth. The thinner film portion has a reduced thickness smaller than the constant thickness. The upper magnetic pole starts to enlarge the core width in the lateral direction at the rear end of the region determined by the so-called neck height. The neck height smaller than the gap depth serves to establish a reduction in the thickness of the upper magnetic pole after the upper magnetic pole gets larger in the lateral direction. A magnetic saturation can reliably be prevented at the thinner film portion in the upper magnetic pole. The front end of the upper magnetic pole is allowed to receive a larger quantity of a magnetic flux. It is possible to reliably enhance a magnetic field for recordation in the thin film magnetic head.

摘要： An acceleration sensor has a ring-shaped movable electrode connected to an anchor part via beams and a fixed electrode facing the ring-shaped movable electrode defining a specific interval, which are disposed on a substrate. The movable electrode is displaced by acceleration approximately in parallel to the substrate and contacts the fixed electrode, so that the acceleration is detected. The fixed electrode is divided into a detecting fixed electrode for contacting the movable electrode and a sensitivity controlling fixed electrode insulated from the detecting fixed electrode. Accordingly, potential differences between the movable electrode and the detecting fixed electrode and between the movable electrode and the sensitivity controlling fixed electrode are independently controlled to control sensitivity of acceleration.

摘要： A magnetoresistive head includes a magnetoresistive element set back from the front end face of the head confronting a record medium for converting changes in a signal magnetic field leaking out from the record track of the record medium into changes in resistance. The magnetoresistive element is connected to a pair of terminals and a sense region is defined between both the terminals. The magnetoresistive element is magnetically coupled to a front flux guide, one end of which is exposed in the front end face of the head, at the other end of the same. The front flux guide is virtually in the form of a rectangle elongated in the direction of the width of the record track of the record medium so as to exceed the sense region of the magnetoresistive element.

A weight supported by beams is disposed at a specified interval from a surface of a semiconductor substrate, and movable electrodes and excitation electrodes are formed integrally with the weight. Fixed electrodes for excitation use are fixed to the substrate in correspondence to the excitation electrodes. Along with this, source electrodes as well as drain electrodes are formed by means of a diffusion layer on a surface of the substrate at positions opposing the movable electrodes, such that drain current changes in correspondence with displacement of the movable electrodes by means of Corioli's force due to yaw rate, and the yaw rate is detected by this current.

摘要： A ring oscillator for circulating pulse edges of two types therein includes an even number of inverting circuits connected in a ring. Each of the inverting circuits is operative to invert an input signal and output an inversion of the input signal. One of the inverting circuits is a first start inverting circuit which starts an operation of inverting an input signal in response to a first control signal applied from an external input. One of the inverting circuits except the first start inverting circuit and an inverting circuit immediately following the first start inverting circuit is a second start inverting circuit which starts an operation of inverting an input signal in response to a second control signal. A control signal inputting arrangement serves to input the second control signal to the second start inverting circuit during an interval from a first moment at which the first control signal is inputted into the first start inverting circuit and the first start inverting circuit starts the inverting operation to a second moment at which a pulse edge initially generated by the start of the inverting operation of the first start inverting circuit and travelling while being sequentially inverted by the inverting circuits enters the second start inverting circuit.

The device also prevents internal scattering of the developer while preventing a surplus supply of the developer to both ends on the peripheral surface of the developer holder. The unique advantages of the invention are derived through the utilization of sealing members having different elastic properties, which assume both bulk removal of excess developer while providing the needed uniform developer thickness. Another embodiment of the invention has the width of the layer thickness control member in a longitudinal direction set wider than the width of the developer holder in a longitudinal direction, and both side edges of the layer thickness control member are positioned outside both side edges of the developer holder. Proper sealing is assured by having the inner side edges of the sealing member positioned inside the side edges of the developer holder and outside the side edges of the image area of the image holder.

摘要： A plan or vertical type thin film magnetic head is produced by a process comprising the steps of: forming a gap separator layer of a non-magnetic material on the surface of a substrate, while the forming process is not limited to plating; forming a mask layer on the gap layer; patterning the mask layer to form a shield; etching the gap layer, while the shield functions as a mask, thereby forming a gap wall having a width narrower than that of the shield independent of the resolution degree of the resist; forming a magnetic pole layer of a soft magnetic material on the surface of the substrate by exposing the resist at a time, thereby the formed magnetic pole layer being separated by the gap wall; and, utilizing the gap wall as a magnetic pole gap of the magnetic pole layer.

摘要： A semiconductor type yaw rate sensor has a substrate, a beam structure formed from a semiconductor material and having at least one anchor portion disposed on the substrate, a weighted portion located above the substrate a predetermined gap therefrom, and a beam portion which extends from the anchor portion and supports the weighted portion. A movable electrode is formed onto the weighted portion, and a fixed electrode is formed on the substrate in such a manner that the fixed electrode faces the movable electrode. When a drive voltage is applied between the movable electrode and the fixed electrode, the beam structure is forcibly caused to vibrate in a direction that is horizontal relative to a substrate surface plane. In this yaw rate sensor, a strain gauge to monitor forced vibration of the beam structure is formed in the beam portion. As a result, the forced vibration of the beam structure can be monitored with a simple structure.
