Title: Production of thin-film magnetic head
Inventor: KUDO HISASHI
IPC: G11B5/31
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion property of first and second magnetic films and to improve characteristics by allowing an embedment film of a specific small thickness to remain until a resist to be used is removed at the time of forming connection holes for connecting the first and second magnetic films to each other on this embedment film. SOLUTION: The first magnetic film 17 comprising a high saturation magnetic flux density material is patterned via a planarization film 12 on a lower layer magnetic core 4 in formation of an inductive head. The resist mask 22 provided with apertures 22a in correspondence to connecting hole forming regions C is formed in order to form the connecting holes for connecting the first magnetic film 17 and the second magnetic film in the embedment film 21 comprising SiO2 . The parts of the connecting hole forming regions C of the embedment film 21 are removed by a reactive ion etching method and at this time the parts of a thickness 20 to 100 nm are made to remain in the bottom. After the resist mask 22 is removed, the entire surface is subjected again to the reactive ion etching method, by which the remaining embedment film 21 is removed.

Filed: 1989-12-11
Abstract: PURPOSE:To suppress the temperature change of an oscillation frequency over a wide temperature range by constituting the oscillator of a first tuning type oscillating element, second tuning type oscillating element and mixer, as elements equipped with three fundamental functions. CONSTITUTION:First and second tuning type oscillating elements 12 and 13 respectively output oscillation signals so that the absolute value of difference between the oscillation frequency at a specified temperature and the oscillation frequency at an arbitrary temperature can be equal and that the code of this difference can obtain a reverse relation. A mixer 17 mixes the first oscillation signal outputted form the first tuning type oscillating element 12 and the second oscillation signal outputted from the second tuning type oscillating element 13 and generates an oscillation output signal with the frequency of a sum for the frequency of the first oscillation signal and the frequency of the second oscillation signal. Thus, a tuning type oscillator can be obtained while reducing the temperature change of the oscillation frequency over the wide temperature range.

Title: Card carrying-out device
Inventor: INOUE MASAKI
IPC: B65H3/52
Filed: 1987-12-21
Abstract: PURPOSE:To ensure stable action of carrying out a card in no relation to a change of ambient temperature by providing a temperature compensating mechanism which cancels the amount of expansion and contraction in accordance with a change of ambient temperature of a feed roller and a reverse roller in their diametric direction holding a clearance between the rollers to a fixed value. CONSTITUTION:From the initialized condition that a clearance (g) is set between a feed roller 5 and a reverse roller 6, when ambient temperature rises, the rubber-made rollers 5, 6 expand in the diametric direction so as to narrow the clearance (g). Simultaneously with this action, also a temperature compensating member 14 thermally expands in the lengthwise direction pulling up the reverse roller 6 to the upper through a base bed 11 accordingly through a roller supporting frame 9. Thus changing a relative position of the reverse roller 6 to the feed roller 5, the clearance virtually cancels its amount of change due to expansion of the rollers 5, 6, and the initially set clearance (g) can be held. Thus enabling the proper clearance to be continually held,stable action of carrying out a card can be always ensured.
