Title: Hydraulic infinitely variable gearbox
Inventor: SAWADA KIYOSHI
IPC: F16H61/42
Filed: 1980-08-19
Abstract: PURPOSE: To prevent the burning of pump by installing a transmission mechanism which interlocks a transmission operating lever and increases the speed of either pump or engine, between a pump and an engine and by interlocking a gearbox and operating the pump at high speed.  
     CONSTITUTION: The revolution of an engine is applied through an input shaft 17 to a hydraulic infinitely variable gearbox 10 which consists of a variable capacity axial plunger pump 15 and a constant capacity axial plunger motor 16. After operating the gearbox properly based on the operation of a throttle lever 14 and a gearshift lever 12 for a tilted plate 19 of the pump 15, the revolution of the engine is transmitted to crawlers from an output shaft 22. When the engine operates at low speed with the throttle lever 14 at a solid line, the gearshift lever 12 is rotated from a neutral position indicated with a solid line. The throttle lever 14 is then interlocked and moved to a position indicated with a chain line through an operation cam 38, a cam follower 42 and an L lever 40, increasing the speed of the engine simultaneously.

Filed: 1979-09-04
Abstract: PURPOSE:To greatly improve the buckling limit of the slab, and to increase the breadthways rolling reduction, by installing the upper and lower push rolls made possible to adjust their roll gap in the direction of thickness, near the vertical roll provided with the lower flange. CONSTITUTION:The upper push roll 3 is vertically moved in order to make the roll gap of the upper and lower push rolls 3, 4 to approximately coincide with thickness of the material S just passing the vertical rolls 1, 1; and the top level of the lower push roll 4 is approximately aligned to the passing level of the material S. The vertical rolls 1, 1 are driven to perform the edging work. The vertical movement of the material S is restrained by the push rolls 3, 4: and the downward movement of the left and the right ends of the dog done is restrained by the lower flanges 2, 2 of the vertical rolls 1, 1; under this condition, the edging work is performed. Since the buckling of the material S is prevented by the rolling mill of the  present invention, even in case of the large thickness-breadth ratio, the breadthways rolling reduction can be increased.

Title: Power converter
Inventor: AREN FURANKU ROZUMAN
IPC: H02M3/28
Filed: 1994-05-02
Abstract: PURPOSE: To enhance the efficiency by combining a synchronous rectifier with a clamp mode pack type power converter thereby conducting an MOSFET rectification device throughout the switching interval. CONSTITUTION: A power MOSFET 101 is shunted through the series connection of a clamp capacitor 321 and a MOSFET switch 322 and the conduction intervals of the power switch 101 and the MOSFET 322 are set exclusively from each other. Amplitude of a reset voltage appearing across a magnetization inductance during nonconductive interval of the power switch 101 is limited by the voltage inertia of the capacitor 321. The constant voltage being applied for driving the gate of an MOSFET rectifier 105 drives the MOSFET rectifier 105 to conduct throughout the reset interval. Consequently, a reverse peak voltage being applied to a diode 323 is lowered and an efficient diode is obtained.

Abstract: PURPOSE:To feed rolling mill oil to each stand or a group of stand to enable lubrication control by making mixing of rolling mill oil and warm water and emulsification just before the rolling mill oil header of each stand and thereby performing change of concentration of rolling mill oil quickly. CONSTITUTION:In a tandem cold rolling mill, rolling mill oil 1 and warm water 2 are fed separately until this side of the rolling mill oil header of each stand. Here, the rolling mill oil 1 and warm water 2 are mixed in a specified proportion through a fixed volume pump 8 and emulsion thus produced is supplied to a strip. At this time, as a means to emulsify the rolling mill oil 1 mechanically, mixing is performed by a mixer 9 in the mixing part of the rolling mill oil 1 and warm water 2. In this feeding method, change of concentration is made by change of voltage of DC motor of a pump 8 from each stand. In this case, change of concentration can be made immediately without delay, as there is no buffer such as mixing tank etc.

Title: Epitaxial channel mos transistor and manufacturing method thereof
Inventor: TANABE AKIRA
IPC: H01L21/31
Filed: 1995-04-14
Abstract: PURPOSE: To enhance the subthreshold characteristics while simplifying the manufacturing steps by a method wherein the impurity distribution is specified so that the impurity concentration in the channel part may be lower in the gate oxide film interface, to be high concentration in the medium depth part while low connection in the deepest part. CONSTITUTION: The impurity concentration in a channel part is lower on the gate oxide film interface becoming a thin high concentration layers in the medium depth while becoming low concentration again in the deepest part. At this time, in case of off time of the channel part, a depletion layer 28 reaches a low concentration layer 24 but most of the depletion layer 28 remains in low concentration layer 28 and the high concentration 25. Since the depletion layer 28 extending from source drain is blocked by the high concentration layer 25, punch through is suppressed. Finally, when the gate voltage is boosted to supply the threshold voltage, the concentration of the low concentration layer 24 is set up to be extremely low level so that the depletion layer 28 may be notably expanded into the low concentration layer 24.

Abstract: PURPOSE: To enable output compensation with a simplified calculation circuit, by obtaning an ideal output voltage of photo sending element by multiplication and subtraction, through the use of output voltage and a variance sensing signal of the photo sensing element in digital conversion.  
     CONSTITUTION: Each component of an output S of a solidstate image sensor 1 consisting of a CCD sensor 1a is inputted to an analog subtractor 3, it is subtracted with an ideal output voltage E ref  to output the variance sensing signal of the element 1, i.e., the compensation value to an A/D converter 4. Digitized compensation value is inputted to a digital multiplier 6 via a storage circuit 5. The upper rank bit X and a correction value Y among the digital outputs of the output S are multiplied to input an output (X×Y) to a digital subtractor 7 and subtraction is made from the lower rank bit Z. Thus, the digital outout of the subtractor 7 is the subtraction of the digital value of the output S by the multiplication of correction value Y with this digital value substantially, and this is an ideal output voltage which is obtained with an approximate equation.
