Title: Method regarding numerical controller
Inventor: TEIMOSHII DABURIYU WAANAA
IPC: G05B19/4093
Filed: 1993-04-06
Abstract: PURPOSE: To automatically control tool movement for cutting the inside of an irregular pocket by referring to a bit map in real time by specifying the pocket by using a limited set of instructions describing the circumference of the pocket. CONSTITUTION: A numerical controller receives an instruction to the cutting of an irregular pocket and stores a bit map 48 indicating cut and uncut materials in the circumference 24 of the pocket after cutting the circumference 24 by referring to apexes 21 in the circumference 21 and a passage generator completes the inside cutting of the pocket without clearly indicating the programming of tool movement by adopting the bit map 48. Since tool movement coordinates are deviated so that the coordinates can roll over in the bit map 48 regardless of a tool starting position 22, the memory capacity can be saved by assigning the bits of the bit map 48 to the picture elements of a physical space 50 for cutting in real time by convoluing the space of the map 48.

Filed: 1991-04-12
Abstract: PURPOSE:To simplify installation work by a method wherein a signal indicating an operating condition of each of an outdoor device and an indoor device required for controlling an operation of an air conditioner is transmitted with wire-less means such as an electromagnetic wave or a laser or the like or a power supply line. CONSTITUTION:An outdoor device signal transmitting and receiving part 6 is fixed to an outdoor device 1. An indoor device signal transmitting and receiving part 7 is fixed to an indoor device 2. A signal relay 8 is fixed to a suitable location so as to enable a signal to be sufficiently transmitted. Each of the outdoor device signal transmitting and receiving part 6 and the indoor device signal transmitting and receiving part 7 performs transmittance and reception of a wireless communication means such as an electromagnetic wave or a laser or the like to each other. In the case where there is something that hinders communication or the like between the transmitter and the receiver, the signal relay part 8 placed at a proper location is relayed and the outdoor device signal transmitting and receiving part 6 and the indoor device signal transmitting and receiving part 7 performs a wire-less communication. Through such an arrangement, the outdoor device 1 and the indoor device 2 perform a transmittance of signal by a wireless communication means and so a wiring for use in transmitting a signal is eliminated.

Title: Copies holding device of collator
Inventor: SATOU YOSHIHISA
IPC: B65H5/14
Filed: 1981-05-25
Abstract: PURPOSE:To improve collating efficiency and accuracy by amplifying the displacement of a thickness measuring lever interlocking with a holding lever when a copy holder holds an abnormal amount of copies, so that micro-switch operating plates are actuated to stop a collator. CONSTITUTION:At time of a normal collating, the end 20 of a thickness measuring lever 4 is adjusted by a screw 8 in such a manner as to pass between micro- switch operating plates 17. In the thus adjusted apparatus, in case of holding copies excessively, a holder 2 is moved to open and the end of the thickness measuring lever 4 is adapted to pivot on a roller 6 and displace, so that a contact rod 20 can not pass between the micro-scwitch operating plates 17 and is brought into contact with the operating plates 17 so as to stop collating. In case of lack of copies, the contact rod 20 is operated in contrast with this to stop collating. In this case a little displacement of the holder 2 is amplified depending upon a contact point of a shaft 21 and the roller 6 with the lever and upon the distance between the contact rod 20 and the operating plates. Thus, the accuracy  can be improved by amplifying a change in thickness.
