Title: Pneumatic bias tire for heavy load
Inventor: OYAGI KATSUKI
IPC: B60C3/04
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To uniformalize the distribution of grounding pressure by forming the outer contour of a tread like mountains having specific bilateral symmetrical vertexes when specified inner pressure is charged, and specifying the distance between the vertexes. SOLUTION: When a tire is assembled in a regular rim and charged with internal pressure of 0.5 kg/cm<2> , the outer contour of a tread is formed like two mountains having two bilateral symmetrical vertexes P with an equator line EL of the tire interposed between them. A circular-arc like recessed area having the center outside of the tire is formed in the tread central part, and a circular-arc projecting area having the center inside the tire is smoothly connected to both sides of the recessed area. The distance B between two vertexes is 25 to 75% of the tread width A, and the outside diameter of the tire in two vertexes P is made larger than the outside diameter of the tire in the tread end TE.  When the tire is charged with 80% of regular internal pressure, the tread outer contour is like a circular-arc formed by a single or a substantially single radius having the center inside the tire.

Title: Device for discharging liquid component
Inventor: DETOREFU KORUTSU
IPC: F04D29/12
Filed: 1992-01-09
Abstract: PURPOSE: To effectively escape the evaporating of leaking liquid components to previously prevent corrosion by providing a heat source consisting of a pair of frictional plates or the like to the cavity where a rotating shaft is penetrated or extended and/or the mechanical member defining it, so that the leaked liquid components are evaporated. CONSTITUTION: A first frictional plate 4 is fixed to a shaft 1 that penetrates through a cavity 3 provided to a device, and also an end seal 6 is provided to prevent the entrance of a liquid into the cavity 3. This end seal 6 is adjoined to a swelling body 7 in the axial direction, and a second frictional plate 5 is fixed to the swelling body 7 by means of a disc spring 8. The end seal 6 is fixed to a casing 2 and is functioned as the receiving seat of the swelling body 7. When a liquid flows out through the seal gap between the shaft 1 and the end seal 6, the swelling body 7 expands in the axial direction, and thereby, the second frictional plate 5 is moved toward the first frictional plate 4 against the disc spring 8, so that both the frictional plates 4, 5 are slidably brought into contact to generate heat, and consequently the liquid is evaporated and escaped.

Title: Manufacture of semiconductor device
Inventor: YASUDA TAKASHI
IPC: H01L29/78
Filed: 1989-01-09
Abstract: PURPOSE:To make it possible to provide a source or drain in either of dopant diffused layers without affecting element characteristics by selectively growing Si on an Si substrate after formation of a gate electrode and then diffusing a dopant into the Si epitaxial layer. CONSTITUTION:A polysilicon gate electrode 1 is formed on an Si substrate 7 and subjected to heat treatment for post oxidation until an SiO2 film 30 having a thickness of about 500 to 1100Angstrom  is formed on the gate electrode 1. During this oxidation, an SiO2 film 31 having a thickness of about 255 to 550Angstrom  is formed on the surface of the Si substrate 7. Si is epitaxially grown to provide an Si epitaxial layer 32 on the Si substrate 7 from which SiO2 film has been removed by etching, whereby the gate electrode 1 is buried by about 1000Angstrom  within the Si epitaxial layer. Dopant ion is implanted at a high concentration to form an n<+>type layer providing source and drain regions 11 and 12. In a MOS structure thus constructed, an LDD structure can be obtained without forming any side wall and, therefore, it is possible to prevent asymmetry in the dopant diffused layer on the opposite sides of the gate electrode.

Title: Controlling method for sheet shape in sheet rolling
Inventor: MATSUMIYA KATSUYUKI
IPC: B21B37/00
Filed: 1979-01-11
Abstract: PURPOSE: To make good the sheet shape, by controlling the flow rate of coolant and temperature distribution of the roll coolant injection nozzle group nearby the sheet edge, so as to increase the gradient of the thermal crown.  
     CONSTITUTION: Only the signal nearby the sheet edge being produced from the shape detector is regressed with the previously set shape function, and thus obtained regression coefficient is sent as the negative feedback to the separate bending force and reverse bending force of the roll bending control system II. Besides, the absolute value of the regression coefficient, as the control command for the gradient of thermal crown of the work roll surface nearby the sheet edge, is used for controlling the flow rate and temperature distribution of the roll coolant injection nozzle group nearby the sheet edge so as to increase the gradient of thermal crown. Accordingly, the shape distortion at sheet edge is corrected by the rolling load controlled in control systems A and B, and by the separate bending force and reverse bending force controlled in the bending control system II.

IPC: H04B3/46
Filed: 1992-01-10
Abstract: PURPOSE:To obtain a circuit not outputting a signal affected by noise by setting an output of a differential signal receiver circuit to a prescribed fixed level when a cable is broken. CONSTITUTION:When one or two cables 102, 103 are broken, a cable defect detection circuit 30 connecting to an input terminal of a differential signal receiver circuit 20 detects a defect of the cables 102, 103, and its resulting output is led to a prescribed fixed level output circuit 40. The circuit 40 outputs a prescribed fixed level when the cables 102, 103 are broken and outputs a single signal being an output of the circuit 20 when no broken cable is in existence from its output terminal 401. Through the constitution above, a signal due to noise caused by the broken cables 102, 103 when the cables 102, 103 are broken is not outputted. Furthermore, the defect of the cables 102, 103 is detected by monitoring a level at the output terminal 401 or the output of the circuit 30.

Abstract: PURPOSE:To non-adjust a video signal processing circuit by inserting beforehand a constant amplitude intermittent signal into two types of a chrominance signal obtained by a line sequential for one horizontal period each and controlling an amplifying ratio so that the intermittent signal can be a constant amplitude. CONSTITUTION:To the output signal (amplitude A) of a process circuit 27, the burst signal of an amplitude (x) for 1H each in a burst additional circuit 28 is added.
