Title: Optical mark reading device
Inventor: HINO NORIO
IPC: G06K7/10
Filed: 1983-01-31
Abstract: PURPOSE:To enable reading of a sheet for optical mark reading by irradiating the sheet written in unspecified color and intensifying the intensity of reflected light by a reflected light intensifying device provided for each color of the sheet. CONSTITUTION:Light projected from a light source 1 onto the part written in the forefront of the sheet 24 for reading optical mark passes through the filter of a rotary plate 2 that changes places at a fixed time interval and enters a sensor 3. A timing plate 18 moves simultaneously with the rotary plate 2 and the mark is read by a light source 19 and a sensor 20. The intensity of light amplified 4 there is stored in a register corresponding to each filter basing upon the result of reading of the plate 18. When the intensity of light corresponding to each filter is stored in registers 9-12, a maximum value arithmetic circuit 13 selects the largest value. Basing on the result of comparison, a filter selecting and controlling circuit 14 sends instruction to a driving controlling circuit 15 to fix the filter of rotary plate 2 corresponding to the register in which the largest value is stored to pass the light projected on the sheet 24.

Title: Desulfurization treating agent for molten metal and desulfurization treatment
Inventor: TAJIRI YUZO
IPC: C21C7/064
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To efficiently execute desulfurization in molten steel while retraining the erosion of a refractory by adding a desulfurization agent composed of specified ratios of MgO and CaF2 and the balance CaO with top-blowing to the molten steel held to a reduced pressure in a vessel lined with a basic refractory containing MgO. SOLUTION: The composition of the desulfurization agent is composed of 5-10 mass.% MgO, 20-50 mass.% CaF2 and the balance CaO. For example, in the case of an RH treating vessel, an immersion pipe is dipped into the molten steel poured into a ladle, and after reducing the pressure in the vessel to 80-100 Torr, the molten steel is started to circulately flow, and after completing the deoxydizing-treatment, the desulfurization agent is injected into the molten steel at the ratio of 0.5-2.0 kg/min/ton together with inert gas such as Ar gas from the top-blown lance arranged at the upper part in the vessel. After completing the desulfurizing treatment, the adjustment of alloy composition is executed by injecting the alloy elements or the like. As the basic refractory, a magnesia brick, magnesite-chromite brick, dolomite brick, or the like, containing 50-80% MgO, is used.

Title: Heat exchanger
Inventor: KATAYAMA MASAYOSHI
IPC: F28D15/02
Filed: 1978-02-10
Abstract: PURPOSE: To prevent the mixing of both heat receiving and radiating liquids by enclosing operation liquid under pressure in a closed vessel having upper and lower surfaces, and arranging a conduit for heat receiving fluid on the upper surface of the closed chamber and a conduit for heat radiating fluid on the lower surface and permitting heat transfer only in one direction.  
     CONSTITUTION: On the bottom surface of a closed vessel 1, a wick 2 made of such as glass fiber is arranged. On the upper surface of the closed vessel 1, a primary conduit 4 for heat receiving fluid is arranged integrally through roll bonding method, and on the lower surface, a secondary conduit 7 for heat radiating fluid is arragned. The closed vessel 1 is heat-insulated by heat-insulating material and supported by outer frames 10 and 11. With these constitution, when heat receiving and radiating fluids are supplied to the primary and the secondary conduits 4 and 5 respectively, operation liquid is evaporated by the heat of radiation fluid, and delivers latent heat to the heat receiving fluid in the upper part, and condenses and drops due to the dead load and circulates. Thus, heat transfer arises only from the lower part to the upper part, and as heat receiving and radiating fluids flow in respective conduits, mixing is prevented.

Filed: 1994-02-09
Abstract: PURPOSE:To increase operation speed and to eliminate the influence of output load by controlling an output level not by a circuitry feedbacking an output signal but by an input signal in a level shifter (output circuit). CONSTITUTION:This circuit is provided with a current mirror circuit composed of pMOS transistors Tr PT3 to PT6. When an input signal IN is supplied to the gate of nM0STrNT1 at 0V and a signal XIN is supplied to the gates of nMOSTr NT2 and NT3 at 5V, TrNT1 is switched from on to off. Tr NT2 and NT3 are switched from off to on and input voltage of 0 V is outputted to an output node ND2. Because the Tr NT3 is also simultaneously turned on, current flows to current mirror circuits Tr PT3 to PT6, the potential of an input side node ND1 is raised to high voltage VEE and the current is supplied to the gate of the Tr PT2. Therefore, the Tr PT2 holds off, the potential drop of the node node ND2 is accelerated and an output OUT is stably held to a ground level.

Abstract: PURPOSE:To simplify constitution, improve the anti engine stall performance, and improve responsiveness and stability by increasing the control quantity of a flow rate control valve in a bypass side passage for idling by the first value for the first time from the time point when the reduction of the revolution speed lower than a previously determined value is detected. CONSTITUTION:The upstream side and downstream side of a throttle valve 5 are allowed to communicate through a bypass passage 35 for idling, and the revolution speed of an internal combustion engine 10 is kept at an aimed revolution speed by varying the control quantity of a flow rate control valve 36 installed in a side passage 35. When the reduction of the revolution speed is detected, the control quantity is increased by the previously determined first value for the previously determined first time. After the lapse of the first time, the control quantity is reduced by each previously determined second value after each lapse of the previously determined second time. When the number of revolution is increased by the increase of the control quantity, and the variation speed of the revolution speed becomes nearly zero, the aimed value of the parameter related to the torque of the internal combustion engine is set, and the control quantity is reduced.

Abstract: PROBLEM TO BE SOLVED: To form a higher accuracy polysilicon resistor by covering the upper part of the resistor with the dielectric thin film of a capacitance element. SOLUTION: After an N-type epitaxial layer is formed on a P-type substrate 11, an island region 21 is formed separately.
