Abstract: PURPOSE:To produce a cold rolled steel sheet having a surface roughness excellent in press formability and distinctness of image after coating by projecting shot grains onto the surface of a cold rolled steel sheet after cold rolling and temper rolling and regulating the surface roughness to a value in a specific range. CONSTITUTION:After a continuously cast slab of low carbon Al killed steel is hot-rolled into a hot rolled steel strip, a cold rolled strip of 1.2mum surface roughness Wca and 0.8mm thickness is produced by means of cold rolling. After continuous annealing is applied to this strip at about 800 deg.C, the surface roughness Wca is regulated to <=0.5mum by means of a temper rolling roll in which surface roughness is changed, and successively, shot grains of 20-100mum average grain size are projected onto the surface of the above strip, by which the proportion of the resulting crater part to the surface area of the steel sheet is regulated to 15-100%, preferably 20-80%, and also the surface roughness Wca is regulated to <=0.7mum. By this method, the cold rolled steel sheet having a surface roughness excellent in press formability and distinctness of image after coating can be stably produced.

Title: Magnetic printer
Inventor: INOUE KUNIHIRO
IPC: G03G15/20
Filed: 1988-04-18
Abstract: PURPOSE:To make printing quality excellent by arranging a light source for warming a visible image between a developing device and a fixing device. CONSTITUTION:The state of an image made visible after development is obtained by forming the image with the toner 312 of plural layers on a magnetic drum 301. At the time of warming the toner 512 with photoirradiation by the light source 505 in the above-mentioned state, the toner 512 surface becomes in a melted state after exceeding a certain temperature. Since paper 509 comes into contact with the toner 512 when a transfer stage is performed in such a state, the visible image on the drum 301 can be faithfully transferred to the paper without being changed with adhesion. Thus, the sharp and high density printing can be easily obtained.

Title: Method for removing scale on surface layer of cast slab in twin roll type continuous casting method and twin roll type continuous casting apparatus
Inventor: MIZOGUCHI TOSHIAKI
IPC: B22D11/06
Filed: 1994-04-11
Abstract: PURPOSE:To simply and surely remove the scale on a surface layer firmly stuck on the surface of a cast slab and to simplify the apparatus by cooling the cast slab obtd. by solidifying with water cooling casting rolls at a specific cooling rate and peeling the scale on the surface layer of the cast slab. CONSTITUTION:After cooling the cast slab C of low carbon steel at >=40 deg.C/sec cooling rate with a cooling device 5 arranged in a carrying position at 600-1400 deg.C of the surface temp., the fully peeled surface layer scale is scattered by spraying pressure fluid from a fluid spraying device 6. The peeled scale can easily and automatically be removed only by spraying the pressure fluid, because the surface layer scale is fully peeled by cooling the cast slab. Further, the peeled scale can mechanically and surely be removed even if this peeled scale remains not scattered by arranging a scale removal device 7 at the downstream side of the fluid spraying device 6. Further, the scale in the partially peeling condition can be removed by adopting a roll type in-line rolling mill as the scale removal device 7.

Title: Capacity controller for compressor
Inventor: TAKESHITA KOUJI
IPC: F04B11/00
Filed: 1980-07-15
Abstract: PURPOSE: To increase the compressed volume of a rotary compressor used for air- cooler, by providing a capacity controller which employes a gas intake pipe having a diameter and a length suitably selected to enlarge variations of intake gas pressure pulsation so as to raise intake gas pressure.  
     CONSTITUTION: A supercharging intake pipe 104 has such a diameter and a length that the inherent value of the air columnar oscillation substantially corresponds to revolutions of a compressor 101. The connection of the supercharging intake pipe 104, in stead of a normal intake pipe 106 to the compressor 101 increases pulsation in intake gas pressure so that intake gas is sucked into the compressor 101 through an intake port upon the maximum pulsation pressure. As the capacity control is of volume increasing type, the compressor can have a specified capacity of the highest perpormance rate, thereby to provide small size compressors.

Filed: 1988-04-20
Abstract: PURPOSE:To obtain high accuracy and increase reliability with a simple structure by providing a check valve for opening/closing an injection valve based on a first negative pressure generated in the intake stroke of an engine or a second negative pressure generated in another stroke. CONSTITUTION:Fuel which is correctly measured by a slow-system and a main- system fuel control portion 1, 2 in accordance with an air flow rate is fed into each injector 3-6 via a fuel passage 20 as a continuous flow. In this case, when the crank angle of an engine is at 0-180 deg., since only a cylinder #1 is in an intake stroke with the other cylinders #2-#4 being out of the intake stroke, only the injector 3 opens a ball valve 22 against the elasticity of a spring 23 to inject the whole quantity of the fed fuel into the air feeding manifold of the cylinder #1. As the crank angle exceeds 180 deg., the intake stroke of the cylinder #1 is finished closing the injector 3. Thus, the fed fuel is sucked by itself in accordance with the intake stroke of each cylinder #1-#4 in order, to accurately carry out the distribution of fuel.

Abstract: PURPOSE:To appropriately cool the continuous steel strips having different qualities with good responsiveness at the time of cooling the strip in the cooling furnace of a continuous heat-treating furnace by switching a three-way valve provided between a cooling water source and a cooling water injection nozzle to control the amt. of the cooling water. CONSTITUTION:A steel strip 2 is passed through the heating furnace and soaking furnace of the continuous heat-treating furnace, introduced into a primary cooling furnace and cooled by a cooling unit 20 consisting of a cooling water source 41 and many cooling water nozzles 23. In this case, a three-way valve 33, a flowmeter 35 and a flow control valve 36 are arranged between the source 41 and the nozzle 23. The amt. of cooling water is determined by the nozzle 23 and the flow control valve 36 when the cooling of the strip 2 is stopped, and cooling water is supplied to the nozzle 23 through the three-way valve 33. When the supply of cooling water to the nozzle 23 is stopped, the three-way valve is switched to a cooling water return pipe 37. Consequently, the strips having different qualities due to welding introduced into the primary cooling furnace are cooled in conformity to the qualities with good responsiveness and not overcooled or undercooled, and the yield of the heat-treated steel strip 2 is not decreased.
