Title: Chain propeller for ship
Inventor: MATSUO YOSHIKUNI
IPC: B63H1/20
Filed: 1982-08-09
Abstract: PURPOSE:To contrive to enhance propelling efficiency and to reduce vibrating forces, by a method wherein propeller blades are fitted to a chain stretched between sprockets, and are driven. CONSTITUTION:Sprockets 14a, 14b are provided respectively at catamaran parts 12a, 12b of a stern, and a chain 17 is engaged therebetween.

Title: Automatic level control circuit
Inventor: NODA ARIHIDE
IPC: H03G3/30
Filed: 1989-05-31
Abstract: PURPOSE:To limit a difference between a harmonic level and a fundamental wave level to a prescribed threshold level by providing a comparison control circuit comparing two DC voltages and outputting a gain control voltage to a high amplifier. CONSTITUTION:A band pass filter 3 passes a fundamental wave component of an output signal, while a band stop filter 4 passes a harmonic component, the signals are rectified and smoothed by rectifier smoothing circuits 5a, 5b respectively and outputted as a fundamental DC voltage and a harmonic DC voltage. The voltages are inputted to a comparison control circuit 6, where their levels are compared, and when the level of the harmonic DC voltage reaches a preset level (threshold level) with respect to the basic DC voltage level, the comparison control circuit 6 outputs a gain control signal. Thus, the gain of a narrow band high frequency amplifier 1a is adjusted so that the level of the harmonic DC voltage does not exceed a prescribed threshold level with respect to the level of the fundamental wave DC voltage.

IPC: G01C19/56
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To enable high sensitivity detection by reflecting the surface acoustic wave, the phase of which is changed according to Corioli's force by a grating reflector to make a standing wave, and detecting a phase deviation. SOLUTION: An angular speed detector is so constructed that an excitation electrode 2 formed by four comb-like electrodes 21-24, first grating reflectors 3, 4, detecting electrodes 5-8, second grating reflectors 9, 10 and a floating electrode 15 are formed on a piezoelectric substrate 1. When the substrate surface part in the position of the floating electrode 15 is vibrated in the direction of Z by a first standing wave made by a surface acoustic wave resonator formed by the reflectors 3, 4 and the excitation electrode 2, a second surface acoustic wave taking the vibration as a source of vibration is generated in the direction of Y and reflected by the second grating reflectors 9, 10 to make a second standing wave.  When the substrate 1 is rotated, the vibration in the floating electrode 15 is deflected to Z-axis by Corioli's force so that the phase of the second standing wave is deviated to detect the rotation.

IPC: B22D2/00
Filed: 1983-07-30
Abstract: PURPOSE:To measure the amount of molten steel highly accurately without the effect of the presence of slag and change in thickness of bricks, by supplying high and low frequency currents to a detecting coil at the bottom of a pot, and measuring the amount of the molten steel based on the impedance of the detecting coil. CONSTITUTION:A high frequency AC and a low frequency AC are alternately outputted from an adder 11 to a detecting coil 14 in the vicinity of the bottom part of a pot, which is formed by an iron skin 1 and bricks 2. The penetrating depth of a magnetic field into molten steel is changed depending on the frequencies by BPFs and detectors 15A and 16A, 15B and 16B. The relative distance between the coil 14 and the molten steel 3 based on the impedance change of the corresponding coil 14 is detected. A voltage, which is proportional to the relative distance and the thickness of the molten steel 3, is detected. The detected voltage is processed by a differential amplifier 17. Thus the measurement of the amount of the molten steel is performed highly accurately without the effect of the presence of slag 4 and the change in thickness of the brick 2 due to the repeated use.

Title: Filter circuit
Inventor: MIYAKE KIMITAKE
IPC: H04N9/79
Filed: 1989-05-31
Abstract: PURPOSE:To effectively avoid the deterioration of a picture quality so as to improve resolution by selecting an output signal nearest to a 0-level when the positive and negative of the signal levels of output signals agree at the time of a signal processing, and outputting the output of the 0-level except for the case. CONSTITUTION:Delay circuits 21 and 25, and band pass filter circuits 22 and 24 generate three output signals SA, SB and SC, all of which consist of the signal components of chroma bands which are delayed by one horizontal scanning line. A correlation discrimination switch circuit 26 is set to select and output the output signals SA, SB and SC whose signal levels are nearest to the 0-level when the output signals SA, SB and SC whose positive and negative agree are inputted. When the output signals SA, SB and SC whose positive and negative do not agree are inputted on the other hand, the signal level of 0-level are selected and the signal level of the output signal SOUT is held to the 0-level. Consequently, the luminance signals which are completely correlated in a vertical direction concerned can be extracted even if the luminance signal components are included in the chroma band.

Title: Palladium brazing filler metal
Inventor: KASHIWAGI KOUZOU
IPC: B23K35/32
Filed: 1984-07-06
Abstract: PURPOSE:To execute brazing of titanium and a titanium alloy at a low melting point, and also to improve the brazing strength by limiting a component composition of a palladium brazing filler metal. CONSTITUTION:A palladium brazing filler metal is constituted of 5-30% silver, 0.25- 7% silicon, total 0.5-20% at least one kind of gallium and germanium by a weight ratio, and palladium as the balance. In this regard, the reason why the component composition is limited is because the melting point is lowered, as for silver, and if the composition is under the limit, the melting point does not fall so mush, and if it exceeds the limit, a joint strength becomes low. Next, silicon is used in order to lower the melting point and to improve the fluidity, and if it is under the limit, the fluidity and a fall of the melting point cannot be expected, and if it exceeds, a brazing material cannot be worked to a plate, a wire, etc. Next, gallium and germanium lowers the melting point, reduces a diffusion of a base metal into a brazing metal, and prevents silver from being melted and divided, and if it is under the limit, there is no said effect, and if it exceeds the limit, working of the brazing material becomes difficult. Also, palladium has a good wettability with respect to titanium, a titanium alloy, iron, copper and nickel, and has a corrosion resistance, therefore, it is an indispensable element.
