Title: Speed detecting device for vehicle
Inventor: WATANABE MASAO
IPC: G01P3/481
Filed: 1986-10-02
Abstract: PURPOSE:To accurately detect the speed or acceleration of a vehicle by providing which makes an AC signal into a rectangular wave, a rectangular pulse counter a circuit device, a time counter device, a time arithmetic circuit, a storage circuit which stores a pulse number count signal and a center position output time signal corresponding to it, and a speed arithmetic circuit. CONSTITUTION:When an AC signal Y1 is inputted from a sensor to the rectangular processing circuit, the rectangular processing circuit converts it into a rectangular pulse Y2 to be outputted. Both slope positions SAN and SBN on both sides of the peak or valley position of the AC signal Y1 are measured and the centers tAN and tBN of the peak or valley are calculated from their mean to reduce effectively the influence of a low-frequency waving component W and a high-frequency noise component N contained in the AC signal Y1, thereby accurately finding intervals of time when each timing tooth 10a passes in front of the sensor 12. Consequently, the speed V and acceleration alpha are accurately calculated in real time based on the found means value TN.

Title: Method and device for performing leveling operation
Inventor: KAARUUEEBAAHAATO BARUDAUFU
IPC: B66C23/80
Filed: 1991-09-17
Abstract: PURPOSE: To provide a method and an apparatus for executing automatic control for making a platform or the like especially for a motor vehicle reach a desired level through the use of hydraulic supporting cylinders at a relatively low cost in such a way that the method and the apparatus are adaptable to usage in areas in which levelling operation is conventionally executed manually. CONSTITUTION: Hydraulic supporting cylinders 1-4 are extended for levelling a body, for example, a platform or vehicle part. As soon as one of the cylinders reaches a supporting position while moving out, further extension of this cylinder is temporarily discontinued. After extension of the last supporting cylinder, i.e., that the cylinder which is the last to reach the supporting position, has been discontinued, the levelling operation is completed by only operating the other supporting cylinders which had previously reached the supporting position. The other supporting cylinders are further extended until the level position is reached.

Title: Power source circuit breaker
Inventor: NAKAMURA GORO
IPC: H01H39/00
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To surely prevent such a situation as reconduction of a power supply circuit by external force of impact, vibration and the like after the power supply circuit is broken forcibly at the time of abnormality occurrence such as short- circuiting of a wire harness and vehicle collision, and to allow reset. SOLUTION: A reset knob 20 is attached to a tip part of a shaft 16, a torsion spring 21 and a return preventing lock 22 are stored deflectedly inside the reset knob 20, and the lock 22 is rotatable around a reset knob supporting point 20a of the reset knob 20 as a shaft by a load of the torsion spring 21. The return preventing lock 22 is projected thereby by force of the torsion spring 21 from an inside of the reset knob 20 integrated to the shaft 16, so as to prevent the shaft 16 and the reset knob 20 from being returned to an initial position. Since the return preventing lock 22 is easily stored to the reset knob 20 manually, a reset operation for returning the shaft 16 to the original initial position is easily carried out.

Inventor: MAEJIMA MIKIO
IPC: B41J2/51
Filed: 1988-09-20
Abstract: PURPOSE:To accurately set a rotary reference position to enhance printing quality by setting the printing element row of a printing head in parallel to the moving direction of the printing head to determine the set position as the rotary reference position of the printing head and setting the objective constant angle of the printing head on the basis of said position. CONSTITUTION:In a serial printer having a mechanism for rotating a printing head, the printing element row of the printing head is arranged in parallel to the moving direction of the printing head in order to reduce a measuring error to perform printing and a position where the printing width thereof becomes minimum, that is the angle of inclination becomes 0 deg. with respect to the moving direction of the printing head is set to a reference angle setting position. Further, in order to shorten the rotary time in the setting of the angle of inclination of the printing head, the dimension between both ends of each printing element of the printing head is made larger than the maximum character dimension height performing magnifying printing and the reference angle position of the printing head is set so as to make the printing element group parallel to the moving direction of the printing head. By making the reference angle setting position parallel to the moving direction of the printing head, only the size of a printing width, that is, a point becoming a position where the printing width is min. may be judged at the time of the adjustment of a reference angle and the printing head can be set to the reference position accurately.

Filed: 1988-09-20
Abstract: PURPOSE:To obtain a water stopping tape with an excellent water stopping effect over a long period by coating a water absorbing paint made of powder/ granular water absorbing resin, a binder, and short synthetic fibers on the faces of a synthetic resin film or the like. CONSTITUTION:A water absorbing layer 5 is coated on both faces of a fabric or nonwoven fabric sheet 4 made of a synthetic resin film or synthetic fibers, and the water absorbing layer 5 is constituted of powder or granular microorganism-nondecomposing water absorbing resin 1, short synthetic fibers 2 and a binder 3. The water absorbing layer 5 of the water stopping tape for a cable contains synthetic resin short fibers 2 in addition to the water absorbing resin powder 1 and the binder 2, thus it is very bulky for the same stuck quantity and thick and flexible, and it contains conduits formed by the short fibers 2 in the water absorbing layer as it is bulky. When water infiltrates into the cable, the whole water absorbing layer instantly absorbs water and is swollen, and the water entering in the longitudinal direction and the inner direction of the cable is stopped only near the infiltration position of water.

Filed: 1983-12-15
Abstract: PURPOSE:To finish the shape of a main section, improve space factor, and uniformalize the distribution of a coil by molding the main section in a completion state and then folding only a crossover section. CONSTITUTION:A deflection coil prototype 22 is molded by winding a winding made of adhesive copper wires, for instance, around a gap 19 formed between a recessed mold 11 and a protruded mold 15 using a flyer for an automatic winding machine and such. Each of front molds 13 and 17 and rear molds 14 and 18 is disassembled and removed and the respective crossover sections 22B and 22C of the deflection coil prototype 22 are exposed. A crossover formation front plate 20 and a crossover formation rear plate 21 are descended and the crossover sections 22B and 22C are bent facing outward. In this case, since a main section 22A is inserted accurately by a recessed central mold 12 and a protruded central mold 16, the main section 22A will not be deformed and there is the possibility of the winding being prevented from losing its shape. Then, the section between the adhesive copper wires is made adhere to each other by heating the wires.
