Title: Oscillating circuit by proximity switch
Inventor: AKASU MASAHEI
IPC: H03B5/12
Filed: 1981-02-10
Abstract: PURPOSE:To improve non-linearity of negative conductance of an oscillating circuit, and to obtain a constant detecting sensitivity characteristic, by connecting a differential amplifier to the pre-stage of a transistor of emitter-follower connection, and providing sufficient current feedback. CONSTITUTION:A differential amplifier 11 is connected to the prestage of a transistor 6 of emitter-follower connection, and sufficient current feedback is provided. Such a constitution removes non-linearity of negative conductance by non-linearity between base-emitter voltage of said transistor 6 for converting a voltage current and its emitter current. As a result, negative conductance of a circuit is not varied by oscillation amplitude, and when detecting whether oscillation exists or not, it is unnecessary to strictly set a comparison level for compating the amplitude, non-adjustment becomes possible, and it is possible to constitute a proximity switch having high accuracy and high sensitivity, which does not depend on a temperature and supply voltage.

Title: Liquid drop jet recording method
Inventor: SHIRATO YOSHIAKI
IPC: H04N1/40
Filed: 1979-02-19
Abstract: PURPOSE:To make it possible to carry out high speed recording at good energy efficiency by bringing an electric-heat converter into contact or proximity with or to a recording liquid and supplying a short pulse-like signal to the converter to carry out recording. CONSTITUTION:An electric-heat converter 4 is brought into contact or proximity with or to a recording liquid 3 present within a working chamber 2 provided with a discharge orifice 6. A pulse-like signal the half-value width of peak energy of which  is within the range of 0.1-500mu/sec is supplied, and the above described liquid 3  is exhausted and sprayed as droplets 7 through the above mentioned orifice 6 in  correspondence to the operating force generated therein, and recording is carried out by the droplets 7 on a surface 10 to be recorded. In accordance with the shortening of the pulse width the response in the exhaustion of recording liquid drop is improved, and energy required for exhausting one liquid drop may be small. Therefore, the pulse of shorter width such as less than 500mu/sec is preferable. However, in accordance with the shortening of the pulse width, it is required to increase the voltage value of the pulse and to heat the electric-heat converter 4 in shorter period of time. For this reason, the limit of the pulse width is 0.1mu/sec from the aspect of durability.

Title: Switchable resonance filter for light emission and manufacture thereof
Inventor: GUREGORII EI MAGERU
IPC: G01J1/02
Filed: 1993-02-05
Abstract: PURPOSE: To provide an optical filter structure which can be switched and provide a manufacturing method for the structure. CONSTITUTION: The structure of an optical filter which can be switched comprises a transparent substrate 10 for radiation to be treated and the substrate 10 includes an electrode 12 or supports the electrode.

The film 22 has a slot 24 in a specified length to resonate with the radiation with a specified wavelength. When the electrode 12 is started, the film 22 is deflected and the fluctuation of the distance to the substrate 10 causes changes of the wavelength of transmitted light.

Title: Vertical display position control circuit for crt display device
Inventor: YAMAGUCHI SHOJI
IPC: G09G1/04
Filed: 1988-01-29
Abstract: PURPOSE:To display a picture in a normal position even at the time of input of a video signal other than a recommended signal by providing a phase control circuit which adjusts the phase of a vertical synchronizing signal by external operation and outputs the adjusted vertical synchronizing signal. CONSTITUTION:In case of a signal other than the recommended signal, a frequency voltage converting circuit 2 takes in an input vertical synchronizing signal V1 and outputs a voltage signal corresponding to its frequency. A phase control circuit 4 takes in the input vertical synchronizing signal V1 and the voltage signal from the frequency voltage converting circuit 2 to generate a vertical synchronizing signal V0 and adjusts the phase by external operation to output the adjusted vertical synchronizing signal V0. If the display position is deviated, a vertical oscillating circuit 6 takes in the voltage signal from the frequency voltage converting circuit 2 and the vertical synchronizing signal V0 and is oscillated synchronously with the adjusted vertical synchronizing signal V0. Thus, the phase state is changed in the phase control circuit 4 by the external operation to shift the display picture to the normal position when the picture is deviated.

Title: Magnetic engine
Inventor: ENDOU KIYOSHI
IPC: F03G7/10
Filed: 1981-02-13
Abstract: PURPOSE:To enable a clean engine to permanently operate, by employing a polarity switching mechanism that acts by magnetic force and physical mechanisms including universal gravitation, physical energies, links, etc. to operate the engine. CONSTITUTION:When a piston rod 2' is energyized vigorously down, the S pole of the field polarity switching magnet 4 touches with 4', and becomes the same porality thereto so that it is vigorously raised also under the influence of repulsion of a spring 11' to compress a spring 11, then its porality is turned to the same porality as the N pole of the field polarity switching magnet, and it is lowered vigorously under the influence of the repulsion. Thus the piston drives a driving shaft 3 through the universal gravitation, the links, the cranks, and a fly wheel 17 to operate the engine, and therefore the clean engine can be operated permanently.

Abstract: PROBLEM TO BE SOLVED: To stably convey sewage by applying the vacuum pressure of a vacuum sewer pipe to an air chamber, and applying the atmospheric pressure to it with a controller detecting that the sewage level of a sewage sump reaches a set level. SOLUTION: When the sewage level of a sewage sump rises and reaches a set level, a controller 33 introduces the atmospheric pressure to an air chamber 30 to increase the air pressure of the air chamber 30. When the vacuum suction force applied to a piston 18 is decreased to below the spring force of a spring 26, the piston 18 is moved to the valve opening direction, and a valve element 13 is opened. When a vacuum valve 10 is opened, sewage flows into a vacuum sewer pipe 1, the vacuum valve 10 is further opened to suck sewage and air. The air conveys the sewage through the sewer pipe 1. When the suction of sewage is completed and the sewage level is lowered, no air is fed to the air chamber 30. As the degree of vacuum of the sewer pipe 1 is recovered, the vacuum valve 10 is closed. The sewage can be stably conveyed.
