Title: Acoustic-optical modulator
Inventor: MORIMOTO KENICHI
IPC: G02F1/11
Filed: 1981-03-25
Abstract: PURPOSE:To simply attain the adjustment to a Bragg angle with just a shift in the uniaxial direction by providing an acoustic-optical modulator attached to a housing plus a control means to give a fine shift to the housing in the direction orthogonal to the optical axis of a lens. CONSTITUTION:The 1st lens 2 which makes the light beam incident to an AO modulator is provided along with an AO modulator 3 that reflects the beam with a Bragg angle and the 2nd lens 4 that turns the primary beam reflected from the nodulator 3 into parallel beams. These component parts are attached to a housing 10. For this housing 10, only the incident angle varies with no change given to the modulator 3 by the function of the lens since the lenses 2 and 4 plus the modulator 3 are set on the same optical axis. If the degree of shift of the housing 10 is refrerred to as (d), the incident angle theta is proportional to the degree (d). In face, however, the incident angle has some shift due to the shift of initialization, a shift error, etc. Thus a fine shift is carried out by a fine shift board to an estimated position where an incident Bragg angle is obtained. In such a way, the adjustment is simply made possible to a Bragg angle.

Title: Production of molten iron
Inventor: ITO YOSHIKI
IPC: C21B11/02
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To control a target value while reducing the carbon concn. in molten iron at the time of producing the molten iron by packed layer system by using a cylindrical furnace. SOLUTION: Firstly, coke containing a flux is charged between the furnace bottom and primary tuyeres 3. This coke is heated by blowing combustible gas and fuel from tuyeres 9 at the furnace bottom, and bed coke 6B having a prescribed layer height corresponding to the target carbon concn. in the molten iron is formed under consideration of the compensation for consumption of the carbon during this operation. Successively, scarp and additional coke are charged in order, and at the time of starting the melting operation, the layer height of the bed coke 6B is estimated from the material balance of the carbon, the cross sectional area of the furnace and the bulk density of the coke based on the analyzed value of the exhaust gas. The charging quantity of the coke is adjusted so that the bed coke becomes a prescribed layer height to control the carbon concn. in the molten iron to the target value.

Title: Pneumatic tire and method for mounting pneumatic tire
Inventor: ITO SHUNGO
IPC: B60C5/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To make stability in steering compatible with low noise characteristic outside of a vehicle, particularly with the decrease of passing noise during acceleration. SOLUTION: Main inclined grooves 14 extending in opposite directions are formed at both sides of the equator surface CL of a tire. The inclination of a groove wall surface in an operating side relative to a vertical line perpendiculer to a tread surface is set to a value smaller than that in a groove wall surface in a kicking out side. In a block 20 partitioned by the main inclined grooves 14, the rigidity of the operating side is relatively lowered, an impact upon abutting against a road surface can be mitigated, and hammering sound upon acceleration can be reduced. Since, in the block 20, the rigidity of the kicking out side is relatively raised, the amount of deformation of the block immediately before kicking out can be decreased. Thus, the amount of slip of the block at the time of kicking out can be decreased and slip sound during acceleration can be reduced.  Since the hammering sound and the slip sound can be lowered at the same time, passing noise during acceleration can be extremely reduced.

Abstract: PURPOSE: To form an active-matrix circuit of a very high integration degree by a method wherein a TFT of a constitution wherein an oixde film obtainable by anodizing a gate electrode material exists on the side surfaces of a gate electrode, and a TFT of a constitution wherein the oxide film obtainable by anodizing the gate electrode material does not substantially exist on the side surfaces of a gate electrode, are respectively used for a switching transistor and a peripheral logical circuit. CONSTITUTION: A metal film is first formed both on a peripheral circuit and a matrix region likewise. Then, the metal film is etched to form gate electrodes 107 and 108 and 109 and 110 on the peripheral circuit part and the matrix part. At this time, it is desirable that gate conductors of the matrix part are provided so that they are all connected electrically with each other and gate conductors of the peripheral circuit part are provided so that they are electrically insulated from the gate electrodes 109 and 110 of the matrix part. A current is made to flow through the gate conductors of the matrix part in an electrolytic solution and anodic oxide films 111 and 112 are respectively formed on at least the side surfaces of the gate conductors of the matrix part.  In such a way, as there is no need to provide specially a wiring for an anodic oxidation in the peripheral logical circuit, the integration degree of an active-matrix circuit is improved.
