Title: Biaxially oriented film based on saponification product of ethylene-vinyl acetate copolymer and its production
Inventor: KATO KUNIYASU
IPC: C08K3/32
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To provide an ethylene-vinyl acetate copolymer saponification product (EVOH)-based biaxially oriented film on whose continuous production scarcely generates troubles and which does substantially not have the differences of various properties between the central side and both the selvage edge sides of the film, hardly causes a hanging flare at the selvage edges of the film, and enables the maximal security of a practically effective width, and to provide a method for producing the EVOH-based biaxially oriented film. SOLUTION: This ethylene-vinyl acetate copolymer saponification product (EVOH)-based biaxially oriented film has the following characteristics. The total content of Na and K metals contained in EVOH is 0. 01 to 50 ppm; the elongation L of the biaxially oriented film in the mechanical direction is <=2%; an average refractive index n is 1.520 to 1.540, when the biaxially oriented film is measured at many points in the width direction of the film; and the inplane dispersion of the average refractive indexes n is ±0.001 or less. The method for producing the biaxially oriented film comprises longitudinally orienting an EVOH unoriented film, latitudinally orienting the film, thermally setting the oriented film, and then cooling the set film.  Therein, in the cooling process, the temperatures of the film are set so that the temperature of the side end regions of the film in the width direction becomes higher than the temperature of the central region.

Title: Hot water controlling plate of gas-fired bath
Inventor: TAKAO NOBUHIRO
IPC: F24H1/00
Filed: 1983-12-05
Abstract: PURPOSE:To enhance the thermal efficiency of the heat exchanger of a bath heater by a method wherein a hot water controlling plate is so constructed as to be kept at both the fully open state and the half closed state and is fully open in order for hot water to easily flow in a bath tub by convection during the bath is heated up. CONSTITUTION:When a bath is heated up, a hot water controlling plate 7 is open as indicated with the single-dot chain lines, resulting in reducing the resistance of hot water flow in the direction indicated with the arrow A and consequently improving the circulation of hot water between a bath tub and the heat exchanger of a bath heater and enhancing the thermal efficiency of the bath heater. On the other hand, when the bath is taken, the hot water controlling plate 7 is half closed as indicated with the solid lines, resulting in eliminating the hot water flow in the direction indicated with the arrow A out of the heat exchanger into the bath tub and consequently in eliminating the danger of being scalded. The titled plate can easily be attached to the existing bath tub.

Title: Tongue and gpoove-prevention steel bar of cantilever beam
Inventor: ISHIBASHI TADAYOSHI
IPC: E01D21/00
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent damage of concrete and steel bars, by installing tongue and groove-prevention steel bars onto which a rubber is integrally formed and stuck, between cantilever beams. SOLUTION: A rubber 20 is integrally formed on the surface of a tongue and groove-prevention steel bar 10 and closely stuck thereto. In this time, it is preferable that rustproof plating is applied on the surface of the steel bar 10 before the rubber 20 is integrally formed. Then, when the steel bar 10 is installed between cantilever beams, the steel bar does not move against the movement of a structure and the rubber follows it owing to the shearing deformation thereof, and hence, the deformation between mutual structures is prevented. In this way, since the steel bar 10 does not directly contact concrete, stresses or shocks which the peripheral concrete 13 of the steel bar receives, are moderated and cracking and delamination can be prevented.  And further, since the steel bar 10 is integrally formed with the rubber 20, corrosion-resistant and deterioration-resistant properties are increased. And since the rubber follows the movement of the structure owing to the shearing deformation thereof, the moving quantity can be appropriately set by changing the thickness of rubber.

Title: Turning type construction machine
Inventor: KOBORI SHINJI
IPC: E02F9/22
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To reduce a burden on an oil cooler to miniaturize the oil cooler by cooling hydraulic oil when the hydraulic oil flows through a return pipe. SOLUTION: In this construction machine, the downstream side of an oil cooler inflow side pipe 19 in a return pipe 18 for returning hydraulic oil from a multiple valve device to a hydraulic oil tank 13 is a rising pipe part 19C for heat radiation, while the rising pipe part 19C is disposed along the front face of a radiator 9 nearly perpendicularly to the flow direction of cooling air supplied from a cooling fan 7. Thereby, when the heated hydraulic oil is returned from the multiple valve device, the cooling air of the cooling fan 7 can cools the rising pipe part 19C for heat radiation. Accordingly, an oil cooler having small cooling capacity, i.e., a small-size oil cooler can be used to reduce a mounting space of the oil cooler.

Title: Vehicle behavior controller
Inventor: NAGATA TOSHIRO
IPC: B60T8/26
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent a reduction in the side force of rear wheels and the occurrence of an unstable vehicle behavior caused by the movement of a load during engine braking in a rear wheel driven vehicle. SOLUTION: In a rear wheel driven vehicle, during engine braking (110: YES), a deviation ΔV (=VR-VF) between the average wheel speed VR of rear wheels and the average wheel speed VF of front wheels is calculated (120 to 140) and, if the deviation ΔV is lower than a first determining value KH (positive value) (150: YES, 170: NO), the braking hydraulic pressure of the front wheel is gradually increased by ΔP (160). If the deviation ΔV is within a range of the first determining value KH to a larger second determining value KR, the braking hydraulic pressure of the front wheel is held (180: NO→190) and, when the deviation ΔV is larger than the second determining value KR, the braking hydraulic pressure of the front wheel is reduced (180: YES→200).  Thus, during engine braking, a relationship between a front wheel braking force and a rear wheel braking force is controlled in the stable region of an ideal braking force distribution and the unstable motion of the vehicle following a reduction in the side force of the rear wheel is prevented.
