Title: Stepless speed changer utilizing planetary gear
Inventor: TOMOYOSE RIICHI
IPC: F16H3/50
Filed: 1980-03-16
Abstract: PURPOSE: To simplify the construction of the titled mechanism and enable to effect a large power transmission by a method wherein the stepless speed changer is constituted with a combination of a ring gear, a sun gear and planetary gears.  
     CONSTITUTION: When an input shaft 1 is rotated, the ring gear 6 and a gear 4 integral with the sun gear tend to be rotated into the same direction through the input shaft 1 and a pair of spur gears 2, 3. At this moment, if a load is being imposed to an output shaft 5, a difference is caused in the number of revolutions of the gears 6, 4 and the gear 6 tends to be rotated reversely by the planetary gears 7, 8 attached to the output shaft 5, however, the reverse rotation is precluded at this moment by the functions of one-way clutches 10, 11 attached to a fixed chassis 9, as a result, the ring gear 6 is fixed. Accordingly, the speed of the output shaft 5 is reduced through the gears 7, 8. When the number of revolutions of the input shaft 1 is increased, the oneway clutches 10, 11 are released and a torque for the output shaft 5 is changed.

Title: Controlling method for shape in universal rolling
Inventor: YOSHIHARA SEISHIROU
IPC: B21B1/10
Filed: 1979-03-22
Abstract: PURPOSE:To make possible the simple operation to control the shape with quick response, by controlling the peripheral speed of one of a couple of opposite rolls independently of another roll, for adjusting the rario of peripheral speeds. CONSTITUTION:Perpendicularly crossing couples of rolling rolls 31, 32 and 41, 42, are respectively driven by the driving shafts 71, 72 and 101, 102; respective driving shafts 71, 72 and 101, 102, are respectively driven by motors 111, 112, and 121, 122; each of these motors is controlled by the motor speed controller 17. In this constitution, the ratio of peripheral speeds V31/V32 of rolls 31, 32, and the ratio of peripheral speeds V41/V42 of rolls 41, 42, are changed to prevent the bending. For instance, when the rolled H beam 1 is bending toward the rolling roll 31, the ratio V31/V32 is increased, and when the situation is inverse, the ratio is decreased. When the rolled H beam is bending toward the rolling roll 41, the ratio V41/V42 is increased similarly to avove.

IPC: H04B7/26
Filed: 1991-02-28
Abstract: PURPOSE:To make the telephone set small by devising the telephone set such that destination information is stored, the destination information is displayed and dialed. CONSTITUTION:A RAM 440 of a radio telephone set 100 registers a destination telephone number together with a name of the destination in advance. The RAM 440 stores various data used when a CPU 410 makes processing. Then the RAM 440 uses a backup circuit to store the storage content even when a power supply is turned off. The destination telephone number is registered to a destination information table of the RAM 440. Then the registered destination information is displayed sequentially on a display section 710 and a desired destination is selected to make dialing. Thus, the telephone set is formed to be a subminiature type in which the operability is sacrified to some degree and the telephone set is made small.

Abstract: PROBLEM TO BE SOLVED: To prevent a high frequency current at the time of welding from flowing as a reactive current through a seam guide roll and then to improve welding efficiency and further quality of welding by forming a seam guide roll used for seam welding out of an inner cylinder made of MC nylon with insulating effect and high compressive colapse resisting strength or an inner tube made of FRP and an outer tube made of steel. SOLUTION: The seam guide roll 1 is formed out of an outer cylinder 2 made of steel and an inner cylinder 3 made of MC nylon or FRP, and is rotatably fitted around a rotary shaft 10 of the seam guide roll through a bearing 4 inserted into the inner cylinder 3. This seam guide roll is in particular suitable for making thin electric welded tube with the ratio of sheet thickness/ outer diameter of <= around 1.5%, and is free from fear of being broken because the roll outer cylinder 2 is made of steel which comes into contact with both of the edges of an open pipe, i.e., the seaming part, and receives high compressive strength at the time of seam welding, and moreover is able to shut off a high frequency current because the inner cylinder 3 is made of MC nylon or FRP.

Title: Method and apparatus for optimizing cost of power circuit network
Inventor: JIEIMUZU EDOWAADO HANUEI
IPC: H02J3/18
Filed: 1991-02-28
Abstract: PURPOSE: To optimize generation and distribution of reactive power in a system comprising a plurality of electromagnetic rotating machines each having reactive power characteristics by providing a controllable exciting element for regulating reactive power being generated from the rotating machine or absorbed by the rotating machine. CONSTITUTION: If a non-zero effective power from an external generation facility is specified during optimization, a swing power, i.e., the difference between a specified effective power being fed from a generation facility and a calculated value, is distributed to all load buses in proportion to the effective power load after repeating Newton-Raphson matrix 56. Consequently, effective power from the generation facility can be measured on-line. If a zero effective power from an external generation facility is specified in the on-line calculation, calculated swing power is entirely born on the external generation facility.

Title: Small-size printer
Inventor: TAKEKOSHI TARO
IPC: B41J9/26
Filed: 1986-02-19
Abstract: PURPOSE:To enable smooth extraction of types and thereby sharp printing by providing the first head which contacts a protrusion at the back of a type and the second head which contacts an adjacent protrusion and causing the first head to contact the protrusion at a required type with a guide means. CONSTITUTION:A hammer 24 is energized by a spring 28 into a counter-clockwise direction, so that a head is pushed out in close contact with a radial wall 16-1 at left of a protrusion 13-2 at the back of a type to be used for printing. Therefore, the type is pressed almost without any shift of a contact point between a hammer head 24-1 and a protrusion 13-2. The second head 24-2 formed at both sides of the head 24-1 has a type pressed on a printing surface, and at the same time that this pressing is performed, adjacent types of both sides are allowed to protrusion to some slight extent. A type wheel 13 is slightly inflated to a type surface side, thus moderating a curvature near a pressed type and reducing the surface curvature of the type itself. This enables sharp printing at right and left ends of the type. In addition, the second head 24-2 gives a rotational moment to a protrusion at the back of an adjacent type, pushing out the type smoothly.
