Title: Rotary pick-place device
Inventor: YAMADA KENJI
IPC: B65G47/86
Filed: 1990-08-02
Abstract: PURPOSE:To realize high speed and high accuracy of the device by operating a gripper unit which holds, transfers, and releases a part by a cam device in the rotary type pick-place device which is used in the assembly of magnetic tape cassette. CONSTITUTION:When an index shaft 1 rotates intermittently, a cylindrical cam 5 is synchronized with a rotary head 2 and rotated in the same direction. When the index shaft 1 stops, the cylindrical cam 5 is rotated reversely, a cam follower 6 is driven by a cam face of the cylindrical cam 5, and a gripper unit 3 on the rotary head 2 side which has a device part interlocked with the cam follower 6 is operated. That is, it is possible for a plural number of the cam followers 6 to perform various movement owing to the setting of a plural number of cam curves, and the gripper unit 3 holds and releases a part, ascends, and descends by utilizing this movement. The gripper unit 3 moves sequentially by the intermittent rotation of the rotary head 2, but the cylindrical cam 5 repeats forward rotation and reverse rotation alternately.

Title: Method for controlling current of voltage source pwm converter
Inventor: KUBO KENJI
IPC: H02M7/219
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To improve phases near LC resonance and to stabilize a current control system by controlling a converter current so that the output current on a converter side may match a current command value, and compensating the output of the current control system by means of a second-order lag filter. SOLUTION: In a voltage control system, an adder 605 adds the difference between a value detected through a low-pass filter(LPF) 601 and a DC voltage command value Vdct to the DC voltage Vdc of a PWM converter 2, and the output of the system is calculated by means of a proportional integrator 606. Then a coordinate transformer 607 converts the output into current command value of each phase. Meanwhile, the voltage control system fetches currents Iu, Iv, and Iw of the converter 2 in each phase via LPFs 602-604, and adders 608-610 add the differences between the fetched currents Iu, Iv, and Iw and the coordinate-transformed results of the output of the voltage control system. Then proportional integration compensators 611-613 calculate the voltage command values to the converter 2.  Then the effects of the resonance between a reactor 4 and an LC filter 5 are removed by providing second-order lag filters 614-616 at each phase, and the outputs of the filters 614-616 are used as the voltage command values to the converter 2.

IPC: G06F13/00
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To attain communication even when a communication protocol address is to be changed dynamically due to the movement of a computer or the like. SOLUTION: When a personal computer(PC) 101a is moved, a current address after revision is informed to an address mapping server (AMS) 102 together with a home address of the PC 101a. The AMS 102 stores each home address of each terminal equipment and the current address to an address cross reference table 501 in cross referencing them each other. In the case of sending/ receiving information to/from the PC 101a, when the home address of the PC 101a is added to the information, a PC 101c snatches away the information by a socket hook processing 201.  The socket hook processing 201 inquires of the AMS 102 about a newest current address of the PC 101a based on the home address of the PC 101a and converts the home address of the PC 101a added to the information into the newest current address obtained through the inquiry and sends the information after the conversion into a socket processing 202.

Filed: 1986-09-01
Abstract: PURPOSE:To improve an abrasion resistance of a friction material, by adding 5-35wt% of kalium titanate fibers of 0.1-3mm of fiber length and 10-60mum of fiber diameter with respect to the entire volume of a friction material for the fiber component. CONSTITUTION:A friction material contains 5-35wt% of kalium titanate long fibers of 0.1-3mm in length and 10-60mum in diameter. With the component, friction is caused among fibers and a mechanical reinforcing effect is maintained so that an abrasion resistance is improved at a high temperature. Further, since a lot of pores can be defined among the fibers, a fade resistance can be improved. In addition, metal fibers or Aramid fibers may be contained so that they reinforce one another and strength as a material can be improved. Therefore, an abrasion resistance and a fade resistance can be improved and an aggressive property to a mating member can be reduced.
