Abstract: PURPOSE:To photograph freely a longitudinal-long screen and a lateral-long screen without moving a camera main body by providing a rotating means for rotating with respect to the camera main body around an optical axis of a photographing lens and rotating an image pickup element by interlocking with the rotating means. CONSTITUTION:After a photographer mounts a barrel 10 on a main body 2, the rotates an operational ring 26 to select the photographing of a longitudinal- long screen or lateral-long screen. For instance, when the photographs the lateral-long screen, the rotates the operational ring 26 so that an index 44 can be coincident with a needle mark 42 of said ring 26. At this time, since an image pickup element 32 of a fitting plate is positioned at the lateral-long photographing, said photographing is carried out in this state. When the longitudinal-long photographing is carried out, the operational ring 26 is rotated until the index 44 is coincident with the needle mark 46. Thus the image pickup element 32 comes to the position of the longitudinal-long photographing, and therefore said type of photographing can be executed in this state.

Filed: 1992-07-08
Abstract: PURPOSE:To reduce the size, the weight and the power consumption by equally dividing a flat piezoelectric body or a movable body which is manufactured by forming a piezoelectric body on the surface of an elastic body in the moving direction, forming polarization change regions in odd numbers, and by forming polarization variable electrodes in odd numbers separately in each polarization change region. CONSTITUTION:Polarization slightly variable upper electrodes 1 are formed in odd numbers separately on a flat piezoelectric body 2, making the body 2 a movable body. A lower electrode 3 is formed or the entire lower surface without a break. By changing the polarization on the movable body, a slight dimensional change is generated. With the dimensional change, the center of gravity of the movable body is moved slightly in the desired direction. Successively, right at the time when a dimensional change of the polarization changed region and a dimensional change in a central region are offset, polarizations of both regions are changed. The same operation is conducted for each region. By repeating such operations, the movable body can be moved in the desired direction. By this method, a linear motor can be made simple-structured.

Abstract: PURPOSE:To contrive both reduction in coupling capacity between windings and improvement in high frequency characteristics by a method wherein a magnetic field, on which a magnetic material is formed on one surface of an insulating film, is wound around a conductive conductor. CONSTITUTION:A magnetic film 4, on which a magnetic material 2 is formed on one surface of an insulating film 1, is wound around a conductive conductor 3. Both ends of the conductive conductor 3 are used by series-connecting the other conductor 11 and a power source 12. Magnetic coupling is generated between the magnetic conductor 3 and the magnetic film 4, which is wound around the conductive conductor 3, by allowing a current to flow in a fixed direction as shown in the diagram, and it works as inductance. Also, an eddy current loss can be made small by thinning a magnetic core of the magnetic material. As a result, the coupling capacity formed between windings can be made very small, and a choke coil optimum for formation of high frequency can be obtained.
