Title: Corrective tooth cutting method for saddle type worm gear
Inventor: UMEZONO SHIRO
IPC: B23F13/06
Filed: 1987-09-22
Abstract: PURPOSE:To improve contact of tooth and to machine front and rear tooth faces simultaneously by tooth cutting a worm through a conical tool with slightly large inter-shaft distance and reduction ratio with respect to relative motion when tooth cutting for worm wheel is formed. CONSTITUTION:Front and rear tooth faces of a worm 1 are tooth cut simultaneously through a conical tool 2 turnable around a center Q so as to form a hob for tooth cutting a worm wheel around the center (q) of the conical tool 2. Inter-shaft distance L and tooth cutting reduction ratio (j) when a worm 7 is tooth cut are set slightly larger than those (l) and (i) when the hob is formed. When a limit normal point on a common normal line 6 is employed as a design reference point P which is separated from the worm shaft 7 by a distance (r0) and gearing angle of the worm and the worm wheel is (delta), tandelta=(l-r0)/(r0.i), while if lead angle is delta' when tooth cutting is carried out, then tandelta=(L-r0)/(r0.j), and if delta=delta' then L=(l-r0).j/i+r0, and thereby the distance L can be obtained by making the tooth cut reduction ratio (j) equal to (i+n) and providing random integers 1, 2,... to (n).

Abstract: PURPOSE: To keep the outer diameter of a boot within a predetermined size when the boot is expanded and constricted by forming a transition segment between a cylindrical segment of the boot and a widening segment starting from a piston rod, in a bulge region having a diameter larger than that of the cylindrical segment. CONSTITUTION: A cylinder 1 is closed by a flexible elastic expandable boot 6 connected to a bottom 4 of the fluid cylinder 1 having a piston 3 and a piston rod 2 by an end surface opposite the piston rod 2.

IPC: H02P27/04
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a controller for controlling the rotational direction in a two-pole AC motor, in which the motor is rotated electrically in one direction. SOLUTION: A two-pole AC motor includes magnetic poles 2a and 2b made of N- and S-poles of a permanent magnet around half circumferential faces of a rotor 1, while magnetic field faces 5a and 5b of a stator are formed at an opposite position to the magnetic pole 2a or 2b. The stator core 4 has coils 6a and 6b wound around it and connected to a two-phase AC power supply. The rotational direction is detected just after the drive of the rotor, and whether the rotor is rotated forward or not is judged on the basis of the detected direction. When the rotor is judged not to be rotated forward, the continuity of power to the coils 6a and 6b is broken and the power is fed again to the coils 6a and 6b after the break.

Title: Setting system for input and output card used for programmable sequence controller
Inventor: OKAYAMA YOSHIHIKO
IPC: G05B19/05
Filed: 1985-10-25
Abstract: PURPOSE:To easily attain the correspondence between the position of an input and output I/O card and an I/O address by allocating the address of the I/O card set at the same position of the next rack in case an I/O card having a larger number of points than the minimum number. CONSTITUTION:The maximum and minimum number of points of an I/O card are set at 64 and 16 respectively and a rack can store eight I/O cards. Then the maximum four racks are prepared. Thus an I/O address can be set with the minimum number of cards using the number of points of the I/O cards set at each rack. Therefore the I/O address can be clearly known quickly at the position of the relevant card. In case an I/O card having a larger number of points than the minimum number is set, the I/O address of the I/O card set at the same position of the next rack is allocated. Thus it is possible to set an I/O card to easily know the correspondence between the position of the I/O card and the I/O address without increasing the number of internal memories.
