Title: Operating method for blast furnace
Inventor: OTOHATA TETSUYA
IPC: C21B5/02
Filed: 1981-10-22
Abstract: PURPOSE:To control the heat of a blast furnace by increasing or decreasing the rate of blowing of fine powder of iron oxide to be blown through the tuyeres of the blast furnace thereby stabilizing the fluctuations in the heat of the blast furnace in a short time without degrading the efficiency of the blast furnace. CONSTITUTION:Iron oxide contg. >=50% iron oxide having <=1mm. grain sizes is suspended in a carrier gas such as compressed air and is blown through the tuyeres of a blast furnace through injection nozzles. The heat of the blast furnace is controlled by increasing or decreasing the rate of blowing of said iron oxide. The iron oxide reacts in two stages of direct reduction which is endothermic reaction and indirect reduction which is exothermic reaction in the furnace, and the rate of said two reactions is changed by increasing or decreasing the rate of blowing of said iron oxide, whereby the furnace heat is controlled. Iron ore, mill scale, etc. are used as said iron oxide, and if the particles having <=1mm. grain sizes are below 50%, the speed of reduction is low and sufficient controlling is not effected; therefore it is necessary to contain said particles at >=50%.

Title: Fitting mounting structure
Inventor: ONO SHOJI
IPC: E06B1/56
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To provide a fitting mounting structure which prevents sounds from being caused by thermal stresses between a fitting and a building frame. SOLUTION: In order to fix the top rail 11 of an aluminum sash 9 to a beam 4F by means of an upper anchor member 40 and a screw 40A, sound deadening sheets 61, 62 and sound deadening washers 65 are interposed between the top rail 11 and the beam 4F. Thus even if thermal stresses are generated because of differences in coefficient of thermal expansion and in amount of displacement caused by thermal expansion between the beam 4F and the aluminum sash 9, the sound deadening sheets 61, 62 and the sound deadening washers 65 restrain vibrations caused by the relative movement between the upper anchor member 40 and the screw 40A, thus preventing the generation of sounds due to the thermal stresses.

Title: Liquid energy breeding device using flow tube
Inventor: SATOU YOSHIO
IPC: F03B17/04
Filed: 1981-10-27
Abstract: PURPOSE:To prevent reduction of fluid energy by providing the flow tube with a part whose sectional area is twice as large as that of other parts and concentrating the pressure due to gravity at the flow tube. CONSTITUTION:The fluid is flowed in the direction perpendicular to the earth by providing the flow tube with a part whose sectional area is larger than other parts. In this part 2 the volume of fluid becomes large to cause increased weight, and the pressure due to the gravity acts directly on the part 3 in adjacency. Because slopes 9.10 are very mild, water pressure due to gravity acts on the slopes 9.10 normally. Accordingly fluid with a large energy flows out of the line 3 and the energy is bred. Thus reduction of the fluid energy is prevented.

Title: Expansion valve apparatus for refrigeration cycle
Inventor: ISHIDA HIDEKI
IPC: F25B41/06
Filed: 1987-07-08
Abstract: PURPOSE: To perform defrosting even of an evaporator using an expansion valve by controlling the opening of a valve in a first opening region at the time of non-defrost operation and controlling the opening over first and second control regions at the time of defrost operation. CONSTITUTION: When a defrost signal is delivered from an evaporator 70 upon adhesion of frost to an evaporator 70 and a microcomputer 120 delivers a forward rotation symbol, a drive circuit 130 generates a value of the forward rotation symbol as a forward drive signal. A stepping motor 60 rotates forward in response thereto and actual number of steps Ra is increased to the maximum number of steps Ro. Consequently, a rod 54 moves upward in response to forward rotation of the rotor 62 of the stepping motor 60 to displace a valve disc 53 up to the maximum stroke thereof. Consequently, the total opening area of an expansion valve 50 is controlled to a value corresponding to the opening of each valve hole 52b, 52c. Since the air flow from a fan 70a is cooled with the maximum flow rate of refrigerant by the evaporator 70, the evaporator 70 is defrosted smoothly.

Filed: 1992-06-29
Abstract: PURPOSE:To accelerate read by providing a first read system reading data while controlling a spindle motor for rotating a CD and a second read system independent of the first read system, and switching both systems and controlling the spindle motor. CONSTITUTION:The first read system is arranged in the inside of the CD 1 and the second read system is arranged in the outside of the CD 1, and the data of the CD 1 is read by switching a selector 15 so as to control by the first read system from a main control part 6 for reading the data in the inside by the nearer first read system. Then, for the data in the outside, the data is read by switching the selector 15 to the second read system from the control part 6 for reading by the nearer second read system. When this process is repeated, and inner and outer peripheries are accessed in random and the data in the CD 1 is read, a range of the read system movement is reduced to half and the loss of an access time is reduced and the access is executed at a high speed.

Title: Infrared detector
Inventor: TAKADA HIDEJI
IPC: G01J5/34
Filed: 1989-06-30
Abstract: PURPOSE:To prevent reradiation by light beams such as visible rays from being made incident on an infrared rays detection element by executing metallic coating such as a mirror surface on the outside circumferential surface of the upper surface part of a container including the surroundings of an infrared transmitting window. CONSTITUTION:A window material 4 is provided form the outside of the container 1. A metal coated layer 13, what is called the mirror surface is formed on the upper surface of a resin mold part 5 around the window material 4 by vaporizing and depositing metal having high reflectance. Since the coated layer 13 is formed on the outside circumferential surface of the upper surface part 2 including the surroundings of the window material 4 in such a way, the light beams of the infrared rays of the visible rays are mostly reflected on the upper surface part 2, the self-absorption of the light at the part of the container 1 except the window material 4 is drastically reduced. As the result, the quantity of the reradiation from the inside surface of the container 1 is reduced and the malfunction of a detector is almost eliminated.
