Title: Electromagnetic attracting device
Inventor: FUJITA TAMOTSU
IPC: B25J15/08
Filed: 1991-10-03
Abstract: PURPOSE:To attraction-hold small thin plate (iron plate) parts and a workpiece to be machined desirably by disposing plural electromagnets in an attracting face in such a way that the respective pole end faces of the electromagnets are leveled with the attracting face. CONSTITUTION:Plural electromagnets 2a-2d are disposed in an attracting face 5 for attraction-holding an article formed of a magnetic body by magnetic force in such a way that the respective pole end faces of the electromagnets 2a-2d are leveled with the attracting face 5. Accordingly, even if the attractive force of the individual electromagnets 2a-2d is made small, necessary attractive force can be obtained on the whole of the attracting face 5. With the attractive force of the individual electromagnets 2a-2d being made small, magnetic saturation and magnetic penetration can be prevented, and small parts can display necessary attractive force by coming in point contact with plural electromagnets 2a-2d. In addition, since plural electromagnets 2a-2d are disposed parallel, the complexity of structure is avoided while obtaining the attracting face 5 of required area.

Abstract: PURPOSE:To enhance removal efficiency, by composing structure in which ozone supplied from an ozonizer is sprayed on a sample surface, and radiating ultraviolet rays to this spraying gas to strengthen ozonic generation so that the amount of ozone is increased on the sample. CONSTITUTION:An ozone-introduced port 3, through which oxygen containing ozone supplied from an ozonizer 2 into a reaction container 1 is sprayed on a sample 6, is installed at the part in front of the sample. Ultraviolet rays are radiated in a space above the sample by a ultraviolet light source 4 and a reflector 5. The reflector 5 is shaped in spheroid. The ultraviolet light source 4 is fixed on a focus position of this spheroid, in structure in which the ultraviolet rays are not directly radiated from the ultraviolet light source 4. Therefore, the sample 6 is irradiated in a scarce degree by light leaking from the ultraviolet light source 34, and ultraviolet radiation scarcely has an effect on even ultraviolet rays hardening-type resist such as positive-type photo resist in a novolac system.

Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To detect a position of a user regardless of the interior and exterior of a house, and detect the position with high accuracy in the interior of a house. SOLUTION: A position detecting terminal 5 carried by a user receives a GPS signal containing position related information (such as longitude/latitude data and time data) from GPS satellites 7a, 7b when staying outdoors to detect a present position on the basis of the position related information contained in a received signal. When staying indoors, the terminal 5 receives infrared rays containing a position ID (an identifying piece capable of uniformly identifying an arranging place) from position ID transmitters 3a, 3b arranged in a proper place to detect a present position on the basis of a position ID contained in received infrared rays. The terminal 5 detects a present position by preferentially receiving the infrared rays when staying in an area (for example, a recreation gound and a zoo) capable of receiving both signals of the GPS signal and the infrared rays.

Filed: 1987-11-13
Abstract: PURPOSE:To omit the mechanical parts like a key lock mechanism, etc., by transmitting a key code string received from a keyboard with reception of a gate control signal and then stopping the gate control signal. CONSTITUTION:A detecting circuit 4 sets a detecting signal (a) at an H level with push of a control key 5 of a keyboard 1. Thus the output signal of an AND circuit 6 is set at an H level. Receiving the signal (a), a gate control FF 11 sets a signal b-1 at an L level. Then a gate circuit 12 stops the transmission of a key code received from the keyboard 1. A memory circuit 8 stores an identification character string supplied with push of keys. Thus the key locking action is through. Then the output signal of an AND circuit 7 is set at an L level with push of the key 5 and the circuit 8 outputs the stored key code string. When the identification character string supplied with push of keys are coincident with the output of the circuit 8, a comparator 10 sets a coincidence signal at an H level. Receiving this coincidence signal, the circuit 12 transmits the key code received from the keyboard 1.

Title: Adaptive type random access satellite communication system
Inventor: SUZUKI MAKOTO
IPC: H04B7/155
Filed: 1987-11-13
Abstract: PURPOSE:To always attain the communication of satisfactory efficiency even to the fluctuation of the wide range of traffic by selecting an aloha system with slor or a pure aloha system according to the size of a using rate with a center earth station, using a descending line and executing an instruction to all terminals. CONSTITUTION:Transmitting data from a terminal 5 are once accumulated in a buffer memory 27 and after that, read by the timing signal of a transmitting timing circuit 26. Then, the data are passed through a modulator 28, a transmitter 29 and an antenna 20 and outputted as the ascending line signal of a frequency f2. The transmitting timing circuit 26 generates a transmitting timing signal based on a random system control signal in control information from a center earth station 1 to be separated by a separating circuit 23. Namely, when the pure aloha system is selected, transmission is started each time the transmitting data are generated regardless of a slot timing. When the aloha system with slot is selected, the transmission is started with synchronizing to the start of the slot timing. Thus, a random access system to adapt to the traffic can be selected and used.
