Title: X-ray analyzer
Inventor: NAKATANI TAKEHIKO
IPC: G01N23/22
Filed: 1986-05-24
Abstract: PURPOSE:To simply calculate the value to be measured at the time of setting vacuum, by inputting average transmissivity to a correctional operation formula preliminarily stored to apply correctional operation to the detection value obtained from an X-ray detection means. CONSTITUTION:A spectroscope 1 is set to a predetermined wavelength position and counting is started by a scaler 3 simultaneously with the start of measurement. A vacuum degree detection signal is sampled at a definite time interval to store the number of sampling times. The sampling data are digitally converted to calculate transmissivity H(P) which is, in turn, added up to the total of transmissivities up to the previous time. The counting of the scaler 3 is stopped simultaneously with the finish of measurement and the average transmissivity Hm during a measuring time is operated by the addition result and a sampling circuit. The count value of the scaler 3 is multiplied by the receiprocal of the average transmissivity Hm being calculated. By this method, a measuring value at a set vacuum degree is calculated simply.

Title: Position detecting signal converter
Inventor: HAYASHI KOICHI
IPC: G05B19/19
Filed: 1992-04-13
Abstract: PURPOSE:To facilitate the miniaturization of a position detecting signal converter together with improvement of the responsiveness and the reliability. CONSTITUTION:A 20-ary adder 12 reads the first digit value of the precedent addition value out of a storage 13 based on the clock signal received from an oscillator 3 and adds this digit value to the difference obtained by a subtractor 5. An up-down counter 14 counts up its value with the carry signal of the first digit received from the adder 12 and then counts down its value with the take-down signal. Then the counter 14 outputs the value equivalent to the position set by the 2-phase pulse signal. A pulse generator 11 outputs the position detecting signal as a 2-phase pulse signal based on the change of the value equivalent to the position set by the 2-phase pulse signal received from the counter 14.

Title: Network for communication
Inventor: TAKAO NORIYUKI
IPC: H04L12/417
Filed: 1993-05-21
Abstract: PURPOSE:To eliminate only a fault station from a logical link and to automatically recover a network operation by generating a token by a specified station and to re-establishing the logical link when a token holding station other than the specified station becomes capable of transmission and incapable of reception. CONSTITUTION:When a slave station 07 holding the token becomes capable of the transmission and incapable of the reception due to a fault or the like, since a set successor addressed to the present station can not be received even when the station 07 executes a solicit successor procedure, the station 07 stops solicitation and transfers it to the reception stand-by state of a valid frame. Then, when communication in a network tentatively becomes silent, the specified station such as a master station 40 or the like generates the token and executes the solicit successor procedure in the case of not knowing a succeeding station. When the station which receives it responds to the station 40 by the set successor, the station 40 sends the token to the station. Thus, the network operation is recovered.

Filed: 1983-07-01
Abstract: PURPOSE:To aim at a significant improvement in the capacity of conveyance, by constituting a conveying system so as to convey earth and sand during engineering works in a way of adding vibrations to a conveyed dust body by means of a conveying pipe being made to vibrate. CONSTITUTION:Each of vibromotive type vibration generators 4 is set up around a taper conveying pipe 3a centering on such a spot as being large in frictional resistance with a conveyed dust body especially in a conveying starting part, a corner part, etc. With this constitution, the conveying pipe 3a is excited in vibromotion. This vibration is added to the conveyed dust body which comes into the same condition as being subjected to a vibrating screen inside the pipe 3a and its grain size is classified so that such dust bodies as being small in a dust diameter are gathered together at the inner surface side of the pipe 3a, thus a viscous earthen film is formed up. With fluidity in this viscous earthen film, frictional resistance is reduced and therefore smooth conveyance comes possible to be done.

Filed: 1989-05-15
Abstract: PURPOSE:To preclude malfunction by discarding all pieces of communication information which are read out until fault processing end information is read out of a buffer storage device when a microprogram control part in a lower layer detects a fault. CONSTITUTION:When a fault detecting circuit 21i of one of microprogram control parts 31 - 3n which operate under the control of a microprogram control part 2 detects a fault, that is reported to the control part 2 and a fault generation display FF7i and an in-fault-processing display FF23i are set. At the same time, a microprogram control circuit 18 is informed and a fault processing routine is started. An interruption from a control part 3i to the control part 2 is inhibited thereafter. Then when recovery processing is performed and FF7i is reset, the state wherein an interruption can be initiated is re-entered. Consequently, communication data which are sent from the control part 3i where the fault occurs to the circuit 18 are sent out before the end of the fault and data which are not received by the circuit 18 yet are all discarded to preclude malfunction.
