Abstract: PURPOSE:To make this converter small, the reduction in weight and to improve the detection sensitivity and the S/N of a weak radio wave by providing an antenna made of a superconducting thin film, a frequency conversion element composed of a Josephson element, a preamplifier and a local oscillator on a single board. CONSTITUTION:A frequency conversion element 4 consists of a tunnel type Josephson element in which, e.g. two superconducting thin films are connected with an insulator. When the element is used to be acted as an SIS mixer, down- conversion of noise by a Josephson current is suppressed. Moreover, a local oscillation wave output of a local oscillator 6 is fed to the antenna 2 at a coupling section 7 by electromagnetic coupling. On the other hand, a signal wave propagated through space is received by the antenna 2 and fed to the frequency conversion element 4 together with the local oscillation wave. Since the frequency conversion element 4 utilizes the superconducting phenomenon, the element 4 has the high sensitivity and a very small signal wave is detected and a stable local oscillation output is obtained.

Filed: 1986-07-29
Abstract: PURPOSE:To accurately control positioning of a flexible semitransparent film specular surface by providing a sensing mechanism, which detects the position of the semitransparent film specular surface to generate a position signal, and a feedback mechanism which outputs a corrected control signal to a three- dimensional display mechanism. CONSTITUTION:Since a semitransparent film specular surface 12 is directly proportional to the pressure difference, the pressure difference is measured to obtain a variable and the motion of the semitransparent film specular surface 12 is indirectly measured by this variable. When it is inputted to the plus terminal of an adder 36, the instruction signal which indicates a desired position of the semitransparent film specular surface 12 is inputted from a computer system 22 through a conductor 26, and the adder 36 outputs the deviation of the position signal, which passes a conductor 42, from the instruction signal passing the conductor 26 to generate an error signal through a conductor 44, and this error signal is fed back from a compensating circuit 38 to a solenoid 18 of a speaker part 14 through an amplifier 40. Thus, the position of the semitransparent film specular surface is controlled accurately synchronously with projection of an image on the flexible semitransparent film specular surface.

IPC: B41J2/325
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a thermal transfer image forming device wherein toner is effectively melted by comparatively low energy of a printing head. SOLUTION: An image forming device carries a two-layers structure film 9 carrying toner and blank form by piling them up to an opposed part of a thermal head 7 and a platen. A current is selectively turned on to a heating element 7-1 to melt the toner 11 on the film 9, and a dot image is formed by selectively transferring to the sheet P. Respective heat conductivities λ1, λ2, and λ3 are so set as to increase successively in the order of a base 9a of the film 9, its carrier layer 9b, and the toner 11. Thereby, heat is transmitted by being concentrated in a reference position 7-1a direction from down to up (in sheet P surface direction from the heating element 7-1) more quickly than thermal diffusion in a lateral direction. The toner 11 in the reference position 7-1a direction is quickly melted by comparatively low heat energy, and transferred to the sheet P.

Title: Distributed feedback semiconductor laser
Inventor: HIRATA SHOJI
IPC: H01S5/12
Filed: 1986-07-28
Abstract: PURPOSE:To obtain simple longitudinal mode and transverse mode operation, and to lengthen life and improve the stability of operation by forming a distributed feedback means to a striped shape and forming flat regions on both sides of the distributed feedback means. CONSTITUTION:Dummy regions 16 having the same diffraction grating structure are shaped on both sides of a striped diffraction grating 5 through flat regions 11. Since the flat regions 11 with no diffraction grating are made narrower than regions (that is, regions in which 5 and 16 are summed up) having diffraction grating structure in such structure, the conditions of exposure, development and etching are made approximately the same as a diffraction grating is shaped on the whole surface, and various conditions can be controlled in the same manner as the whole-surface diffraction grating. Consequently, the narrow width striped diffraction grating 5 can be shaped uniformly to a section given an element function with excellent reproducibility. That is, the diffraction gratings in the dummy regions 11 are not worked as elements, and the diffraction grating having the same function as there is a diffraction grating only in a narrow width striped diffraction grating is acquired with high yield.
