Title: Method and apparatus for cooling hot steel sheet
Inventor: MIZUTA SHIGEO
IPC: B21B45/02
Filed: 1979-05-21
Abstract: PURPOSE:To increase the water's flow rate density, and to contrive the increase of the cooling range and capacity, by employing the nozzle possessing the intake smoothly formed into an upward bell-mouth in length 2-5 times of the inner diameter, and the several internal guide vanes, at cooling the hot steel sheet. CONSTITUTION:The cooling apparatus is constituted as follows; at the bottom of the water tank 10, the cooling water nozzle 3 provided with the intake of smooth bell-mouthed shape in length (h) 2-5 times the inner diameter (d), being internally partitioned by several guide vanes 7 passing the central symmetry axis, and also provided with the open-and-shut shutter 8 at the nozzle's end face, is installed; the cooling liquid is discharged from the nozzle 3 at the discharging speed suitable for making Reynolds number of the cooling liquid at the exit of the nozzle 3 to be 2X10<4>-6X10<4>, on purpose to cool the hot steel sheet. As a result, generation of the contracted flow and the voltex flow in the nozzle 3 is prevented, and the cooling capacity is increased, besides, the adjustment of the cooling water's flow rate according to the necessity can be done by the shutter 8 so that the pumping power is reduced.

Abstract: PURPOSE:To calculate the ruggedness of an object by irradiating one point of the object with light in a spot, knowing the positions of the spot in an observed picture at two observation points, and calculating three-dimensional coordinates of the spot. CONSTITUTION:The irradiation light from an optical fiber 3 is reflected by a scanning mirror 8 to scan on the object 9 as the spot 9, and fixed mirrors of image fibers 1 and 2 shift in position axially; and an image of an P with parallax corresponding distance l is transmitted to the fibers 1 and 2 and inputted to TV cameras 35 and 36 through image forming lenses 31 and 32 to display spots P(x1, y1) and P(x2, y2) on TV monitors 39 and 40. Interfaces 41 and 42, on the other hand, process them which are inputted to a CPU45. Scanning timing information on a mirror driving unit 43 is supplied to the CPU45 through an interface 44 to calculate coordinates (x), (y), and (h) of the spot P of the object 9 from pieces of spot position information from the image fibers 1 and 2 and the timing information from the unit 43.

Title: Cleaning composition
Inventor: TERASAWA KIYOTOMO
IPC: C23G5/032
Filed: 1990-03-12
Abstract: PURPOSE:To provide a cleaning composition which has a high cleaning effect, is excellent in safety, workability etc., and can be used as a chlorofluorocarbon substitute for, e.g. cleaning a printed wiring board by using isopropyltoluene as its constituent. CONSTITUTION:Isopropyltoluene is used as the essential constituent to produce a cleaning composition. Since isopropyltoluene has high solubility in fat and high detergency for rosin flux and oil or fat, in is possible to readily clean oily stains on the surface of glass, metal, plastic, etc. Because isopropyltoluene has a somewhat high boiling point ad is almost immiscible with water, it is sometime difficult to completely remove from a rugged surface. By adding a surfactant to isopropyltoluene, the isopropyltoluene can be easily removed by washing with water.

Title: Method and device for opening plane grille
Inventor: ANDO KAZUAKI
IPC: E06B9/01
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To obtain the functions of escape in an emergency, and prevention of crime by arranging an operation device for opening a plane grille in a hous ing section to be installed to a window frame or a position adjacent to the window frame and by making the operation device inoperable when the Shoji screen is open and easily operable only when the screen is closed. SOLUTION: When a Shoji screen is opened, a tension spring 7 and a flexible wire 8 operate through pulleys 9, 10, and a pull door 6 is pulled up and a lever operating hole is closed. At this time, the upper portion of a projected lever is folded and stored in a storing section 1. Also, when the pull door 6 fully closes the lever operation hole, a stopper stops the movement of the pull door 6 and, if the screen is opened, the tension spring 7 opens. Because of this, if the screen 12 is opened, a rotation lever 3 for opening the plane grille is stored in the storing section 1, the lever operating hole is closed, and opening operation for plane grille becomes impossible from anywhere. By doing this, in emergency, the lever is pulled upward, then the flexible wire 4 is pulled and the plane grille opened, and easy escaping can be assured.

Title: Inside and outside air changeover box
Inventor: KURIHARA TAKESHI
IPC: B60H1/00
Filed: 1981-04-22
Abstract: PURPOSE:To reduce the resistance to the flow of air and the noise thereof, by integrally molding the corners of the inside and outside air changeover damper of an automobile air conditioner as V to prevent vortexes from taking place in corner zones which would be defined in a changeover casing by the corners of the damper and the casing. CONSTITUTION:An inside and outside air changeover box 1 includes a casing 1a made of synthetic resin. A damper 3 is fitted on the casing 1a and a metal- made shaft 2 rotatably supported. The corners of the damper 3 are shaped as V. Air leak prevention packings 4 are bonded on the obverse and reverse sides of the damper 3 which communicates with the suction port 11c of a blower 11 through an outside air suction port 5, an inside air suction port 6 and a central outlet port 7. Since the corners 3b, 3c of the damper 3 are shaped as V, a dead space K in which the flow of air would swirl in an inside air suction mode F and a dead space L in which the flow of air would swirl in an outside air suction mode G are eliminated. This results in reducing the resistance to the flow of air and the noise thereof.
