Title: Ink jet recording method and ink jet head using that
Inventor: SAKURAI KIKUICHI
IPC: B41J2/14
Filed: 1990-03-15
Abstract: PURPOSE:To prevent transmission of low heat flux due to generation of bubbling nuclei of film boiling by decreasing deterioration of a heating means without adiabatic quick temperature rise by a method wherein ink jetting energy is generated by using variation in volume velocity of a steam bubble group to be generated when a homogeneously nucleating condition is realized and the homogeneous nucleus grows after generation to form the steam bubble group. CONSTITUTION:Ink 4 is brought into direct contact with a surface of a heating element, and the heating element is rapidly heated by applying a super high speed electric pulse to a heating zone. A heating liquid layer called an active layer is formed near a contact interface in such rapid heating. Further, by applying high heat flow speed continuously to the active layer, bubbling by homogeneous nuclei is generated. When the active layer is heated to a homogeneously nucleating condition, many fine steam bubbles 3 are generated in the active layer. Thereafter, the steam bubble grows as a nucleus, and one or a plurality of bubbles are formed while bubbles are repetitively being united with one another. Thereby, large ink jetting energy is generated in a pressure chamber, and ink is jetted from a nozzle hole 7 stably at high flying speed.

Abstract: PURPOSE: To reduce the resistance value without lowering the sensitivity by arranging an extremely fine oxide particle film and a film made of second extremely fine oxide particles with an average grain size smaller than that of the film on the insulating support substrate.  
     CONSTITUTION: A pair of electrodes 2 and 3 are formed on the insulating substrate 1 made of glass, ceramics or the like and an extremely fine particle film 4 of metal oxide such as tin, titanium, zinc and nickel is formed thereon. The film 4 is superlaid with a film 5 made of extremely fine particle the same as that of the film 4 but smaller in the average size. Such double structure of the extremely fine oxide particle films with the average size of the upper film smaller than that of the lower film can improve the electric conductivity of the extremely fine oxide particle without impairing the sensitivity thereof due to external factors including gas and steam.

Title: Optical waveguide tester for detecting connector type connection point and terminal or breaking point using highly sensitive quadratic differentiator
Inventor: OGAWA YUTAKA
IPC: G01M11/02
Filed: 1995-03-24
Abstract: PURPOSE: To make possible highly reliable detection without being affected by noises or the like by a method wherein a light pulse emitted at a specified time interval is applied to an optical waveguide to be tested and back scattered light is converted into an electric device signal to judge whether an output wave from a quadratic differentiator is a Fresnel reflected wave or not. CONSTITUTION: A quadratic differentiator operated with a template is prepared to discriminate Fresnel reflection and a fused type connection point automatically. From the quadratic differentiator, an optical pulse reflects on an end face of an optical fiber at a connector type connection point, on a breaking surface, at a termination or the like and hence, a square waveform is formed. The template allows favorable reaction to a Fresnel reflected wave rising in a pulse to obtain quadratic differentiation waves ΔP and -ΔP in opposite polarity to each other at the falling part of the Fresnel reflected wave.  The differentiation waves ΔP and -ΔP are generated at the rising and falling parts of the Fresnel reflected wave, the interval corresponds to the width of the optical pulse applied to an optical waveguide to be tested and can be specified as a Fresnel reflection point with a waveform judging device.

Title: Constant weight weighing device
Inventor: MATSUO YOICHI
IPC: G01G13/24
Filed: 1988-03-19
Abstract: PURPOSE:To enable accurate weighing and to improve operation efficiency by turning on a display means provided on a weigher and displaying the weighed value of merchandise on a display part when the weighed value reaches a specific weight value. CONSTITUTION:When the weighing of scales #1-#10 is started, LEDs L1-L10 as arrival display means start blinking, but they illuminate continuously when the weighed values of merchandise reach the specific weight and then blink at shorter intervals when the weighed values exceed a permissible range. Further, the display part 5 displays the weighed values and set weight values. For example, when merchandise is mounted on, for example, the scale #1 little by little to start weighing the merchandise, the LED L1 begins to blink and the display part 5 displays the weighed value of the scale #1. Then when the weighed value reaches a set value or upper-limit value, the LED L1 illuminates continuously. Here, when the weighed value exceeds the upper-limit value, the LED L1 blinks faster, so a small amount of merchandise is removed and a check is made.
