Title: Operating state detection for controlling motor-driven golf car
Inventor: JOURNEY JAMES C
IPC: B60L11/18
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To maintain a sufficiently high speed while the full range of the available torque is maintained by adjusting the operating characteristic of a motor, by obtaining a field current for a prescribed operating state in accordance with a prescribed field current level when an armature current signal indicates the occurrence of an operating state. SOLUTION: When a golf car starts to go up a hill and an armature current reaches a preset data point of about 150 A, etc., an adjust signal is generated and the variation of a field current occurs, resulting in an increase in the available torque. A plurality of armature current levels corresponding to the armature current expected at a specific gradient of the hill is designed in a controller 5. Preferably, the adjust signal is generated proportionally to a desired field current level at a prescribed armature current level. Then, the field current is adjusted and the speed torque is consistently increased. Therefore, the going-up performance of the golf car is improved.

Abstract: PURPOSE:To ensure a high-quality reproduction, by carrying out an optical recording to a vertical magnetic anisotropy layer having a high coercive force during the recording and detecting the relfected light sent from a vertical magnetic anisotropy layer having a large magneto-optical effect and a low coercive force during the reproduction. CONSTITUTION:The light given from a laser beam source 15 is irradiated to a writing layer 11 having a low Curie point and a high coercive force via a half mirror 16 and a condenser lens 17 to be recorded by a magnetic field coil 18. At the same time, the light from the source 15 is polarized by a polarizer 21 and irradiated to a reading layer 13 having a large magneto-optical effect and a low coercive force through a half mirror 16 and a condenser lens 17. This polarized light causes the rotation on a polarizing surface by the Faraday effect, is reflected by a reflecting film 12, passes through the layer 13, and causes the rotation again on the polarizing surface to be supplied to a detector 22. Then a change is detected for the degree of rotation on the polarizing surface, and this detected degree of change is converted into the electric signal through a photoelectric transducer 23 for the reproduction.

Title: Planetary gear train for automatic transmission
Inventor: OKUBO MASAHIRO
IPC: F16H3/62
Filed: 1986-04-30
Abstract: PURPOSE:To improve the torque ratio and the efficiency, by providing respective brakes on a turbine shaft for connecting a turbine with a ring gear of one of transmissions and on a stator sleeve shaft for connecting a first stator with two sun gears, and providing a clutch between both the shafts. CONSTITUTION:At the first gear speed, a reversing force of a first stator 36 is transmitted from a stator sleeve shaft 44 to a sun gear 16 of a planetary gear assembly 12, and the reversing force of the stator 36 is added to a forward force of a turbine 34 to be transmitted through a sun gear 14 and a ring gear 22 connected to a turbine shaft 40 to a planetary gear 24 and a planetary carrier 18, thereby improving the efficiency and the torque ratio in a reversing region of the stator 36. Then, at the second gear speed where a brake B1 only is operated to go on, the stator 36 is locked in a speed ratio region until the stator 36 becomes idling, thereby increasing a power to be transmitted from the turbine 34. Further, as the stator 36 becomes idling in the speed ratio region before a second stator 38 become idling, the loss due to a fluid in a stator section is reduced to thereby improve the efficiency in this speed ratio region.

Title: Comparator
Inventor: TOMITA YOSHIHIRO
IPC: H03K3/02
Filed: 1981-06-30
Abstract: PURPOSE:To obtain a digital comparator having hysteresis characteristic, by giving digital variable control to the level of detection with an output of detection. CONSTITUTION:An RL1 and an RL2 show comparison levels 1 and 2, respectively, and RL1>RL2 is set. A selector SEL is set at the side of RL1 before detection of signal significance, and the comparison level of a magnitude comparator MGC is set at the level of the level RL1. An input signal A changes from a small to large value and exceeds the level RL1, and as a result, the output of a detecting terminal C is set at 1. In this case, the selector SEL is switched to the comparison level 2, and no change is caused to the output 1 at such a degree that gives a change to the signal A at a level approximate to the RL1. When the signal A is reduced less than the level RL2, the output is set at O. Thus the selector SEL is switched again to the level 1, and no change is caused to the output O if the signal A has a change at a level near the RL2.

Abstract: PURPOSE:To lift a liquid to a place higher than the pump head with a low head characteristic pump by forming the atmospheric air into fine bubbles through fine holes bored in a bubble mixing means and by feeding them into the lift liquid in a throttle pipe. CONSTITUTION:The atmospheric air is fed through a feed air pipe 6 into the lift liquid flowing through a throttle pipe 1 as fine bubbles from fine holes 3 bored in a bubble mixing means 2. Then, the lift liquid having passed the throttle pipe 1 becomes a mixed phase fluid mixed with fine bubbles in a discharge pipe 4, and the mixed phase fluid has a specific gravity lower than that of the lift liquid itself, although to a different degree depending on the mixing amount of fine bubbles. Therefore, the mixed phase fluid is lifted by the pressure that the resistance loss of the throttle pipe 1 is reduced from the discharge head of a pump 9, and the mixed phase fluid, with its head exceeding the maximum discharge head H of the pump 9, is lifted and fed to a higher lift liquid place 8, thus enabling to lift the liquid to a place higher than a low lift liquid place 7 that would be available normally.
