IPC: F16J15/16
Filed: 1981-09-07
Abstract: PURPOSE:To increase the life of an O-ring, in a roof-typed groove in which the O-ring is housed, by arranging dimensions of said roof-typed groove with the width to about 1.7 times a diameter of the O-ring and the depth to about 0.7 times the diameter in both ends of the groove while equal to the diameter in the central part. CONSTITUTION:An O-ring 1 is housed in a roof-typed groove, and the roof- typed groove is formed to a dimensional shape such that a sloped angle alpha of the grooove is about 20 , and width C of the groove is about 1.7 times a diameter W  of the O-ring 1, while depth of the groove is about 0.7 times the diameter W in both ends of the groove and equal to the diameter W in the central part. As a result, the O-ring 1, when not is use, can be released from compression and returned to almost a circular section of free shape.

Title: Control method for voltage-type converter
Inventor: SHIODA TAKESHI
IPC: H02M7/12
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To control the power factor of a fundamental wave to a specific numeric value, by detecting a source voltage by a controller, outputting an instantaneous reactive power command proportional to the squared value of the source voltage so as to cancel a leading phase component by the capacitor of a ripple absorbing filter, and combining it with an instantaneous effective power command for performing DC voltage control. SOLUTION: A reactive power commanding device 15 receives as an input a source voltage Vs detected by a source voltage detecting circuit, computes the reactive component of the filter capacitor generated by the filter capacitor from its effective value and the fundamental frequency of the source voltage, inverts its sign and outputs it as an instantaneous reactive power command Q* to an AC control computing means 14. A lagging reactive component to be controlled by this instantaneous reactive power command Q* and a leading reactive component by the filter capacitor cancel each other, and the current of the power source has only an effective component, by an instantaneous effective power command P* for performing control equal to former control. Accordingly, the power factor of the fundamental wave is controlled to one.

Title: Support structure
Inventor: YAMATO MITSUTERU
IPC: F16S3/06
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to increase the distances between connection points for multiple expanding and contracting members and a base structure and to increase the storability and rigidity, and to facilitate attitude and position precision control in space by using link mechanisms which can be expanded synchronously with an expansion structure to be supported. SOLUTION: The expanding and contracting members 1 to 3 are coupled with the expansion structure 40 through universal joints 4 to 6 and there coupled with link mechanism 11, 12, and 13 through joints 7, 8, and 9. After the link mechanisms 11 to 13 are expanded with the driving force of a spiral spring, the latch mechanism of a hinge operates to restrict the relative rotation of a rod-shaped member and thus a truss structure is approximately obtained to form a rigid structure. The expanding and contracting members 1 to 3 move two cylindrical members through the driving of a motor to vary the relative distance between the expansion structure 40 and base structure 30, and the expansion structure is rotated on a spherical joint 10 as a pivot point around a pitch axis, a roll axis, and a yaw axis to perform attitude control.

Title: Power transmission device
Inventor: DAN REN
IPC: B25J19/00
Filed: 1994-05-31
Abstract: PURPOSE:To prevent production of a backlash and to reduce a maintenance cost by a method wherein at least one or more gears of bevel gears are energize by a repulse member and other gears are energized from above, the small part of one bevel gear is pressed against and engaged with the small parts of other bevel gears. CONSTITUTION:A bevel gear 9 is placed between bevel gears 4, 5, and 8 in such a state to be engaged with the bevel gears 4, 5, and 8. The bevel gear 9 is always energized downward through the force of a repulsion member 10. Meanwhile, the small part of one bevel gear 9 is engaged between the small parts of other bevel gears 4, 5, and 8. Thereby, the bevel gear 9 is reliably engaged with other bevel gears 4 and 5 and a backlash produced between the bevel gears is prevented from production. Further, since the bevel gear 9 is lowered according to wear of the bevel gear, even when wear occurs, reliable engagement is practicable.

Title: Calendar reading controller
Inventor: SHIODA HIDEAKI
IPC: G06F1/14
Filed: 1992-06-03
Abstract: PURPOSE:To enable a CPU to instantaneously read out the calendar data with use of a simple software that is not conscious of the updating time of a time register. CONSTITUTION:The calendar data are produced counting at an output clock base 2 of an oscillation circuit 1 and performing the carry conversion at a carry arithmetic part 3. A data latch 9 is provided between a CPU 8 and a time register 5 to latch the calendar data on the register 5, and the CPU 8 reads out the data latched by the latch 9 via a multiplexer. Then, the time point when the data on the latch 9 is updated is decided by the input signals 10 and 11 which are inputted to a NAND gate 9A. That is, the latch data are usually updated at the fall of the signal 10 which is kept at 'H' while the register 5 is updated. However, the updating of the data is inhibited with a latch data updating inhibition signal 11 which is kept at 'H' while the data are read out of the CPU 8. Then, the latch data are updated after the reading is through with the data of the CPU 8 and at the fall of the signal 11.
