Title: Determination of metal composition
Inventor: KATOU OSAMU
IPC: G01N33/20
Filed: 1979-03-02
Abstract: PURPOSE: To determine speedily and easily the kind of material, the pressure or absence of heat treatment, the composition of heat treatment, and the amount of residual austenite, etc., by measuring the thermal electromotive force produced by giving an optimum temperature difference to the junction of two kinds of metals.  
     CONSTITUTION: Test specimens consist of two kinds of metal materials A, B, which are brought into contact with each other. Contact measuring terminals 2 and 3 are placed so that their ends come into contact with A and B. Terminal 2, materials A, B and terminal B form a closed circuit. In this circuit is provided thermal electromotive force indicator W. On the other hand, in order to give a temperature difference to the junction of materials A and B, terminal 3 is set in the condition of room temperature. Terminal 2 is fitted with heater H. Terminals 2 and 3 are connected to temperature difference indicator T, which shows a temperature difference between the two terminals. Consequently, by measuring the thermal electromotive force between the measuring terminals, it is possible to determine the metal composition, etc. non-destructively.

Abstract: PURPOSE:To impart necessary sliding resistance strength to the surface of a coating compd. coated on a substrate and to prevent attraction between a magnetic head and the surface lubricating agent of a magnetic recording medium by coating the surface lubricating agent in the form of speckles onto the surface of said coating compd. CONSTITUTION:The surface lubricating agent 5 is coated in the form of speckles on the surface of the coating compd. coated on the substrate 1. Namely, the coating compd. formed of a solvent, filler 2, magnetic material 3 and binder 4 by kneader kneading   ball mill kneading filtering stages is uniformly coated on the surface of the aluminum substrate 1 finished to a specular surface by diamond grinding. The surface lubricating agent 5 is further coated in the form of speckles on the surface of the coating compd. after the coating compd. is subjected to orienting, curing and working of the coated film. The coating of the surface lubricating agent 5 to a required thickness on the coating compd. and the reduction of the effective contact area of the magnetic head and the surface lubricating agent 5 of the magnetic recording medium are, therefore, possible. The necessary sliding resistance strength is thus imparted to the coating compd. by thick coating of the surface lubricating agent 5 thereon and the attraction of the magnetic head and the surface lubricating agent 5 of the magnetic recording medium is prevented.

Filed: 1980-02-29
Abstract: PURPOSE:To stop the carrier surely after the completion of transmission of data, by counting clock pulses of the same frequency as the transmission speed and by stopping the carrier of the modulating part when the count value becomes a fixed value. CONSTITUTION:At the completion of transmission, data output part 10 outputs the last parallel data 13 to PS converting part 12.

Inventor: TERASAWA TAKESHI
IPC: G09G3/34
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of realizing a high quality image display. SOLUTION: This liquid crystal display device 1 includes a liquid crystal panel 3, a display signal control part 7, a light source control part 6, a light source drive part 5 and a light source 4.

Abstract: PURPOSE: To prevent stoppage of a fuel grain in an empty chamber and obtain smooth dropping of fuel into an intake passage of an intake device in which the empty chamber communicated through a small passage is provided above the intake passage, by forming a bottom face of the empty chamber in such a manner as to be sloped toward an opening part of the small passage.  
     CONSTITUTION: In case that above an intake passage 44 an empty chamber 38 having a small passage 40 is communicatably provided through a joint 42, an increase of intake passage volume at the downstream side of a throttle valve 36  permits the supply of mixture to its downstream side through the throttle valve 36  even after an intake valve 26 is closed. Accordingly, inertia of flow movement of  intake air can be maintained till the intake valve 26 is opened, thus an excessive  lowering of charg ing efficiency at a low degree opening range of the throttle valve  36 can be prevented. In such an intake device as provided with the empty chamber  38, a bottom face 39 of the empty chamber 38 is formed so as to be sloped toward  an opening part 46 formed at a top end of the small passage 40. In this way, a fuel  grain is not stopped in the empty chamber 38 but gradually dropped into the intake  passage 44.

Title: Visibility measuring instrument

Filed: 1988-02-05
Abstract: PURPOSE:To accurately calculate the visibility of an object by correcting a brightness difference discrimination threshold value according to the observation time of an observer who sees the object and the visual field size of the object. CONSTITUTION:The display time or observation time of the object whose visibility is to be found is inputted to a display time (observation time) and field angle dimension condition setting part 3, which outputs a corresponding signal to a brightness difference discrimination threshold correction part 8. The correction part 8 already inputs a reference brightness difference discrimination threshold value from a brightness difference discrimination threshold value calculation part 7 with a signal corresponding to equivalent light screen brightness and a signal corresponding to center hole adaptive brightness, so the observation and field angle of the object are used for correction to calculate corresponding brightness difference discrimination threshold values, which are outputted to a visibility calculation part 9. The calculation part 9 calculates the visibility (VL) with the input signal from a brightness difference calculation part 4. The visibility is found from the difference between the brightness of the object and the brightness of the background and the ratio of the brightness difference discrimination threshold values. Various positions in the visual field and the dimension and visibility of the object in the observation time are measured at a time.
