Title: Cap with pouring cylinder
Inventor: OMI HIDEHIKO
IPC: B65D47/40
Filed: 1993-06-07
Abstract: PURPOSE:To form a preventive piece of the liquid spilt in a liquid-collecting groove from dripping on the outer periphery of outer wall of a cap body, so as not to hinder molding work of the cap. CONSTITUTION:A preventive piece 20 against dripping liquid is formed upward through a hinge so as to enable folding-back, at the inner periphery of outer peripheral wall of a liquid-collecting groove 10 formed at the outer periphery of the pouring cylinder 11 of a cap body 1. And after it has been molded, it is folded back to face inward and diagonally downward. The preventive piece 20 against dripping liquid not only prevents the liquid in the liquid-collecing groove from dripping outward therefrom on pouring the liquid but also prevents the liquid from leaking out in the closed state of cap. In this way, even if there is a preventive piece against dripping liquid, the cap body together with the preventive piece can be molded as a unit and hence, the production efficiency can be remarkably increased.

Filed: 1977-12-28
Abstract: PURPOSE: To devise an improvement of magnetic characteristics by adhering end surfaces of legs and yoke irons piled up with sheet irons by adhesives containing magnetic powders.  
     CONSTITUTION: End surfaces of legs 12aW12c piled up with sheet irons 12 respectively and yoke irons 13a, 13b piled up with sheet irons 13 respectively are butt jointed and these junction portions are adhered by adhesive 14 containing magnetic powders. Adhesives containing magnetic powders have a stability for a temperature rise of a junction portion and are used those having a desired permeability using such as epoxy-resin etc. of high adhering strength in which reduced iron powder of high purity, sprayed iron powder or magnetic powder such as of silicon containing iron are kneaded.

Filed: 1994-07-12
Abstract: PURPOSE:TO obtain good recording and reproducing characteristics in a short time and to prolong the life of a magnetic head by forming the front end of the magnetic tape-sliding surface of the magnetic head to an approximately hyperbolic shape. CONSTITUTION:The shape of the front end of the magnetic head in the head scanning direction of the magnetic tape-sliding surface of the magnetic head is formed to the hyperbolic shape having a radius R of curvature decreasing near a head gap and increasing the further from the head gap. A solid line 9 in Fig. shows the shape of the sliding surface of the magnetic head and a broken line 10 shows the sliding surface shape of the conventional magnetic head expressed by the single radius of curvature. Both surfaces intersect with each other at points A, A'. Then, the conventional magnetic head of the broken line 10 is larger in the cross sectional area by 1s, 1s' than the solid line 9 in the initial period of traveling of the tape and, therefore, the wear rate is slower with the conventional head. The solid line 9 is larger in the cross sectional area by 2s, 2s' than the broken line 10 when the tape travels up to points A, A' and, therefore, the magnetic head having the hyperbolic shape is slower in the wear rate. As a result, the stable head tape contact state is obtd. by short time of running-in traveling and the longer life is obtd.

Title: Proportional flow control valve
Inventor: SUMITA MAMORU
IPC: F16K31/06
Filed: 1990-06-19
Abstract: PURPOSE:To prevent the generation of abnormality of a flow characteristic due to the striking noise and collision resiliency caused by a valve which is separated from a seat or is seated by providing at least one groove in a circumferential direction, on a sliding part of a valve or/and of a moving iron core. CONSTITUTION:When an electromagnetic coil 6 is electrified, a moving iron core 4 is attracted to the side of a fixed iron core 2 against the pressing power of a return spring 5, and a valve assembly body 18 is moved, and a valve is opened thereby. The resilience force generated by the separation following the very small vibration of the valve assembly body 18 caused by the control, or by the collision at the time of being seated, is absorbed by a spring 15 for energizing a valve 14. Since a groove is provided on the inner circumferential surface of the valve, in a circumferential direction, the range in which there is a possibility that the pressure distribution becomes inhomogeneous in the cross section in a diametrical direction, on the gap between the valve 14 and the contracted diametrical part of the moving iron core 4, is limited to the portion excluding the groove, namely, to the range between each groove, and the sides of both ends. The deterioration in sliding ability due to pressure unbalance can thus be suppressed.

Title: Induction motor
Inventor: KOBAYASHI KAZUO
IPC: H02K17/16
Filed: 1980-11-17
Abstract: PURPOSE:To enhance the efficiency of an induction motor and to reduce the vibration and noise of the motor by reducing the skew angle of a rotor conductor at the side of lagging the skew smaller than that at the side of leading the skew, thereby reducing the harmonic iron loss and the stray-load loss. CONSTITUTION:When a skew is formed at the conductor slot 7 of a rotor 3, the skew angle theta1 at the side of leading the skew with respect to the rotating direction is reduced smaller than the skew angle theta2 at the side of lagging the skew. In this manner the magnetic flux of an air gap 6 is uniformalized over the entire axial length, thereby eliminating the locally concentrated magnetic flux.

IPC: G05G5/05
Filed: 1990-06-18
Abstract: PURPOSE:To perform exact adjustment of dimensions of a rod guide by clamping a first cylinder member of the rod guide until a second cylinder member is relatively displaced with respect to the first cylinder member, thereafter loosening clamping of the first cylinder member up to the position at which the relative displacement started, to complete the adjustment of dimensions of the rode guide. CONSTITUTION:For a steering ratio variable means 11, in order to perform determination of dimensions of the rod guide 35 of an output rod member 16 whose stroke is displaced in the direction of car-width in response to front wheel steering angle, an output rod 36 is first clamped to a clamping jig 72. When a first cylinder member 35A at the lower side is clamped and it is confirmed by a displacement gage 73 that the displacement of a second cylinder member 35B begins, the first cylinder member 35A is returned in the direction of loosening itself so that the second cylinder member 35B returns to the position at which its displacement began, and thereby the so-called back lash between the rod guide 35 and the output rod 36 is eliminated. Then, the dimensions of both the cylinder members 35A, 35B are determined using locknuts 35C, and both the cylinder members 35A, 35B are fixed to set the rod guide 35 at a specified length.

Title: Braking force control device for vehicle
Inventor: NIHEI TOSHIHISA
IPC: B60T8/1766
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To perform suitable vehicle braking even when a vehicle is moved backward by enlarging the pressure intensifying gradient of liquid pressure in a wheel cylinder of a rear wheel when the vehicle is moved backward more than when the vehicle is moved forward. SOLUTION: This braking force control device 1 includes a wheel speed sensor 11, a G sensor 12 and a backward moement detecting sensor 13, and a brake actuator 20 is operated in response to a control signal of an ECU 10. It is detected whether the vehicle runs along a steep slope or not, or whether the vehicle moves backward on a steep slope, and according to these detection results, ABS control processing is conducted when a driver operates a brake. In the rear wheel cylinder, the control is conducted to enlarge the pressure intensifying gradient of liquid pressure at the time of moving backward on the steep slope more than the pressure intensifying gradient when it is not in the steep slope moving backward state.  Thus, at the time of moving backward on the steep slope when load of the vehicle is largely applied to the rear wheel, the braking force for the rear wheel can be increased so as to improve braking force of the vehicle.
