Title: Cascade lock detection method of four wheel drive vehicle and antilock brake control method
Inventor: OKUMOTO NOBUAKI
IPC: B60T8/58
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To detect cascade lock without using a G sensor by obtaining a difference between wheel speed of a front axle and wheel speed of a rear axle when a degree of deceleration of estimated car body speed is larger than a predetermined value and judging that a vehicle is in a cascade lock condition when the difference of wheel speed is smaller than the predetermined value. SOLUTION: Wheel speed of each wheel 15, 16, 17, 18 is obtained by a wheel speed sensor 51, and furthermore, estimated car body deceleration is obtained based on fluctuation of wheel speed. The estimated car body deceleration is compared with a predetermined value, and if it is larger than the predetermined value, a difference between front wheels and rear wheels is obtained based on wheel speed of four wheels. If the difference between the front wheels and the rear wheels is within a predetermined scope for more than a predetermined period of time, it is judged that a vehicle is in a cascade lock condition. When it is in the cascade lock condition, antilock brake control in a low μ passage is done.  In the case of high μ passage, it does not stay in the cascade lock condition for more than a predetermined period of time because the difference between the front wheels and the rear wheels merely crosses a section between predetermined scopes in a short time.

Title: Method for inspecting external appearance of cylindrical matter
Inventor: YAMAGAMI SUMIO
IPC: G21C17/06
Filed: 1985-08-16
Abstract: PURPOSE:To take in an image having high reliability and to enable continuous processing, by transferring cylindrical matter to the direction at a right angle to the rotary axis thereof while rotating the same at a constant speed. CONSTITUTION:A pellet P is placed on one set of transfer rollers 1 to be fed to the right and the rollers 1 are rotated clockwise.

Title: Squid fluxmeter
Inventor: TAKADA YOICHI
IPC: H01L39/22
Filed: 1994-07-11
Abstract: PURPOSE:To obtain a SQUID (Superconducting Quantum Interference Device) fluxmeter in which the amplitude of output voltage is not decreased even if an ABCF method (for lowering the current field sensitivity through asymmetric arrangement of bias current injecting positions) is combined with an APF circuit (for positive feedback through mutual inductance) by setting the joint of a positive feedback circuit at a position symmetric to the SQUID. CONSTITUTION:Although the bias current injecting position and the output voltage take-out position of a SQUID 2 are arranged asymmetrically to the inductance of the SQUID 2, the take-out ports of an APF circuit 3A comprising a resistor Ra and an inductance Li are arranged symmetrically to the inductance of the SQUID 2. This arrangement offsets the current noise from the APF circuit 3A thus eliminating the effect of thermal noise generated from the resistor Ra.

Abstract: PURPOSE: To prevent the failure of a tank mounting part by reducing the rocking load of liquid in the tank in such a way that the upper part of the cross sectional area in the horizontal direction of the tank of a construction equipment is formed smaller than the lower part thereof so that a liquid amount in the tank remains a little bit in the upper part. CONSTITUTION: A part 11 of the upper surface of a fuel tank 10 is approximately horizontally formed, and the most of the other parts 12 thereof is slantly formed so that the surface area Sf of the oil level (a) of fuel oil 6 when a tank is fully filled with the oil can be set smaller than a tank bottom surface area Sb . When the fuel oil 16 is in such a condition that the tank is fully filled therewith or almost filled therewith even though the fuel tank 10 is inclined and vibrated when a hydraulic excavator is operated, a condition that the surface area Sf of the oil level (a) is smaller than the bottom surface area Sb can be retained so that the rocking load of the fuel oil 16 can be suppressed smaller. When the fuel oil 16 in the fuel tank 10 is reduced half or below, the mass thereof is also diminished.  Therefore, harmful effect that exerts on the mounting part of the mounting seat bracket 14 of the fuel tank 10 by the rocking load hardly occurs.

Title: Closed forging method
Inventor: OOTA MASATAKA
IPC: B21K1/30
Filed: 1990-07-11
Abstract: PURPOSE:To prevent deformation and damage of a forging die caused by excessive forming load by escaping a part of one of a die and a punch and lowering the pressing force of a place having an excessive bearing in forming a tooth form part. CONSTITUTION:First of all, a forged part 20 is pressed by the pressing force between the die 24 and the punch 23. When the pressing force is elevated, a billet 20 enters the tooth form 24c of the forging die 21 and a tooth form part 20a short of an under fill is formed. In this case, since the billet 20 enters the tooth form 24c, the forming load is very high and a site having an unnecessarily high bearing is generated. Consequently, when the tooth form part 20a is formed, since a part of one of the die 24 and the punch 23 is escaped, the pressing force of the position having an excessive area pressure falls. Therefore, the forming load is reduced as a whole and the forging die 21 is prevented from deformation, damage.

IPC: B05D1/40
Filed: 1983-09-30
Abstract: PURPOSE:To reduce the generation of striae even if a high-viscosity resist liquid is used when coating a substrate to be treated with a resist film by spin coating by performing the formation of a coating film with inverting a spin direction after a spin speed reaches the predetermined speed and the predetermined time has passed. CONSTITUTION:A motor 5 is rotated inversely in the state that a resist liquid is dripped and a substrate 1 is spinned till the predetermined speed is attained and a film thickness is determined. The motor 5 does not drive a head 3 directly, but a chuck part is connected to a spin shaft rotating at a high speed in a moment through a clutch in this constitution, so that an inverse spin of the head 3 can be done without a difficulty. Striae 8 generated with being bent in the spin direction are diminished and start to be extinguished. At the same time, dryness progresses and the film cures in the state there exists almost no stria.
