Abstract: Head chips (104a,104b) having gaps (105a,105b) of mutually different widths (19µm,39µm) are laminated in close contact with each other in the widthwise direction of the gaps, and are mounted on a rotating drum. Windings (107a,107b) respectively wound around the head chips are selectively operated by a driving circuit (Fig.4). By means of this selection, one or adjacent ones of the plurality of windings are adopted as an object of operation, and during recording a recording current is supplied to the winding selected, while during reproduction a reproducing current is fetched from the winding selected. An effective gap width contributing to recording and reproduction is a total of the gap widths of the head chips around which the windings thus selected are wound. The track width on the magnetic tape is determined by the effective gap width. Accordingly, the track width is variably set as the windings are selectively driven.

Abstract: A piezoelectric transformer includes a substrate (12) of piezoelectric material, preferably a single crystal of LiNbO₃. The substrate is uniformly polarized in a selected direction P and vibrated at a resonant frequency in the length direction. An input voltage (Vi) is applied across the thickness of the substrate by input electrodes 14a, 14b and thus excites the vibration by way of the piezoelectric effect. This causes another voltage in the direction of the thickness of the substrate in an output portion, which voltage is taken out by output electrodes 16a, 16b as an output voltage (Vo). As a result, it is possible to decrease the output impedance, to obtain a large load current and thus fully to heighten the step-up ratio of the piezoelectric transformer.

Abstract: A power transmission device for a vehicle comprises a first power transmitting path for transmitting engine output to a wheel side via a reduction gear, a second power transmitting path for transmitting engine output to the wheel side via a stepless speed change gear mechanism, a path switching clutch for switching between the paths to transmit by one of the paths, a switch-over control part for controlling switch-over operation of the clutch according to a driving condition of the vehicle, and a rotational condition abrupt change restraining part for restraining an abrupt change of a rotational condition of an engine output shaft at switch-over between the paths. The restraining part adjusts to conform rotating speeds of the input and output sides of the clutch to each other at switch-over of the clutch, or conform output torque to the wheel side between before and after switch-over of the clutch. Thus, an abrupt change of rotation of the engine output shaft is restrained to prevent a shock owing to switch-over, and the durability of a friction element is enhanced.

Abstract: A thin film of a solution of at least one noble metal alcoxide is formed on a substrate, then dried and baked either in a reductive atmosphere to produce a thin film of metals or in an oxidative atmosphere to form a thin film of metal oxides. Said solution of noble metal alcoxides may contain merely a single component or a plurality of components. In addition, a solution of metal alcoxides containing at least one noble metal alcoxide as main component or as additive in minor amounts may be used in place of the solution of noble metal alcoxides. Said thin film of metals or metal oxides can be formed as a single layer or as a plurality of layers. 
     Since the thin film formed on said substrate is baked in said reductive or oxidative atmosphere, not only a single-component thin film but also a multi-component thin film can be inexpensively formed without using a complicated and large-scaled apparatus. In addition, since a solution is used, it is also possible to control the crystalline and amorphous structure of noble metal alcoxides or metal alcoxides or the compactness in the case where a porous thin film is formed.
