Title: Electromagnetic log sensor
Inventor: TAKAHASHI KAZUFUMI
IPC: G01C21/10
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To prevent an output from being changed due to the contamination of an electrode part and to prevent a noise from being generated due to the contact of the electrode part with a fluid floating object by a method wherein a magnetic field is generated in water by a coil and the electrode part which detects an electromotive force generated in the magnetic field is covered with an insulator. SOLUTION: In an electromagnetic log sensor, a coil 40 is wound on a core 30, and one pair of right and left electrode parts 50 are arranged with reference to the advance direction of a ship. Then, an exciting current is made to flow to the coil 40, and a magnetic field Φ is generated in water. At this time, when a fluid such as water, seawater or the like flows in the direction of an arrow, an electromotive force which is proportional to a flow velocity V is generated from the electrode parts 50. At this time, the electrode parts 50 at the tip part of the electromagnetic log sensor are covered with an insulator 10 such as, e.g. a ceramic or the like. Consequently, the electrode parts 50 do not come into direct contact with the fluid, and they are not contaminated with a stuck substance. As a result, it is possible to prevent an output from being changed due to a contamination and to prevent a noise from being generated due to the contact of the electrode parts 50 with a fluid floting substance.

Filed: 1990-07-10
Abstract: PURPOSE:To securely decide the fault of the air fuel ratio sensor by providing at least two out of three fault detecting means and outputting a fault signal by at least one of the two fault decision means. CONSTITUTION:A 1st fault decision means constitutes a 1st fault decision means together with detecting circuits 35 and 36 to decide the deterioration and open circuit of a heater and other connecting circuits.

A 3rd fault decision means fetches air fuel ratio signals from 1st and 2nd air fuel ratio means and decides pump cell fail unless the input values are within a specific permissible width range. A controller 37 cooperates with a pump cut circuit 39 to function as an in-fault stop processing means and performs feedback control over the amount of injected fuel according to the air fuel ratio signals. Consequently, the fault of the air fuel ratio sensor is securely decided and in case of a fault, the air fuel ratio feedback control is stopped immediately.

Title: Additive injection apparatus
Inventor: JIYAN KURUUPU
IPC: F04B9/10
Filed: 1987-07-23
Abstract: The invention relates to a device for injecting a metered product into a main circulation of liquid, comprising a metering piston (28) coupled to a stepped piston (11) whose motion results from the pressure of the main fluid in a known manner. The piston (28) interacts with a metering cylinder (10) which is in permanent communication with the lower part of the liquid outlet chamber (8). The mixture of the products is thus confined to the outlet of the device, while no leakproof sliding of a component on contact with either of the liquid and product is necessary, and this eliminates the risks of abrasion of the seals due to deposits on the sliding component. In addition, since the inlet chamber (6) for the main liquid is annular, it permits a filter (33) to be easily installed.

Title: Control device for on-vehicle electrical equipment
Inventor: NAKAJIMA HITOSHI
IPC: B62D1/18
Filed: 1989-07-17
Abstract: PURPOSE:To detect overload accompanied by the driving of electrical equipment accurately by comparing the change of physical signals accompanied by the movement of the electrical equipments with the specified comparison value to detect the state of overload and changing the above-mentioned comparison value according to the fluctuating degree of supply voltage. CONSTITUTION:The rotating speed of an actuator 5, that is, the moving quantity of a tilt mechanism (the rotational position thetaM of a motor) is detected by a tilt sensor 7. An arithmetic and control part 3 calculates the rotating speed, that is, the moving sped DELTAthetaM/DELTAt from the rotational position thetaM. DELTAt is the sam pling interval of the voltage of a battery 6. When this speed value is lower than the threshold value TH, over load is judged. Hereupon, the battery voltage V is monitored at a detecting part 1 and incorporated into the arithmetic and control part 3, and the threshold value TH is obtained as the map value corre sponding to the incorporated voltage value V. In the above-mentioned case, a tilt drive part 4 is de-energized to stop the actuator 5.

Title: Joint structure of rubber crawler
Inventor: TSURU EIJI
IPC: B62D55/253
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To reduce the compression force added to a steel cord to improve the durability of a rubber crawler by setting the overlapping length of the rubber crawler width directional center area of a joint part shorter than the overlapping length of the lateral end area. SOLUTION: The center area So of a steel cord 1a is set short, and a steel cord 1b is cut at a right angle to the longitudinal direction. Accordingly, the steel cords 1a, 1b are mutually overlapped, whereby the overlapping length Lo of a center area So is shorter than the overlapping length Ln of an end area Sn. The length of the center area So of the steel cord 1a is regulated, whereby Lo can be equalized to 0. Accordingly, the overlapping in the center area So of the steel cord 1a is designed to avoid the concentration of compression force in traveling. Therefore, the repeated compression force can be made relatively small, which results in the improvement in the durability of a rubber crawler.
