Abstract: PURPOSE:To reduce the number of signal lines by connecting a main station comprising small-sized computers installed in a machine room and a remote station comprising small-sized computer provided in each floor or a cage with a couple of signal line respectively and adopting the signal transmission as the series transmission by the bus system. CONSTITUTION:When the main station MS outputs address data A10 to a trans mission line 26 at a time T1, the remote stations RS1-RS3 input it respectively and check whether the address is the own assigned address or not and when the said address is an address assigned to the own station, then whether the address is used for output or input is discriminated and the data is inputted/ outputted to the transmission line 26 at a time T2. That is, the remote station RS1 inputting the address data A10 awaits the next data D0, because the address is the own assigned address and used for input. Then the main station MS sending the address data A10 checks immediately whether the data is used for output or input and inputs/outputs the data. Then the main station MS outputs the data D10 stored in it to the transmission line 26 at a time T2 be cause the data is used for output. The processings above are executed continu ously until the address A 15.

Title: Ejector for deep tank
Inventor: IKISU TAROU
IPC: B01F5/04
Filed: 1979-03-23
Abstract: PURPOSE: To eliminate the limit for the economically effective water depth of the ejector and at the same time to reduce the capacity of the aeration tank by placing a nozzle and a diffuser vertically downward and ejecting the jet stream vertically downward.  
     CONSTITUTION: Nozzle 4 and diffuser 7 are placed vertically downward, and a jet stream is ejected vertically downward from the ejection port at the end of diffuser 7. By this, since the capacity of the pump in use becomes the up and down displacement of the liquid in air exposure tank 1, it is possible to neglect the pump head difference due to the water depth and to eliminate the limit for the economically effective water depth of the ejector. Further, since oxygen use efficiency becomes remarkably large in proportion to the water depth in use, it is possible to make the capacity of air-exposure tank 1 small.

Title: Sintered body of cast iron powder
Inventor: OOKAWAKU TAKAAKI
IPC: B22F8/00
Filed: 1983-03-04
Abstract: PURPOSE:To manufacture a sintered body of cast iron powder having uniform and superior sintering effect and mechanical properties at both surface and central parts even in case of a large thickness by blending cast iron powder with Fe-P alloy powder and powder of pure iron, a low ferroalloy or the like and by molding and sintering the blend. CONSTITUTION:When a sintered body is manufactured using cast iron powder produced in a cast iron cutting stage as a starting material, the sintered body has inferior mechanical characteristics because of the high graphite content. In order to improve the inferior characteristics, cast iron powder is blended with Fe-P alloy powder and powder of pure iron, a low ferroalloy or the like so as to adjust the P content to 0.01-1.0wt% and the C content to 0.7-2.5wt%, and the blended cast iron powder is press-molded and sintered. The added P activates the cast iron powder and the pure iron or ferroalloy powder during the sintering, and at the same time, graphite is diffused into Fe. A sintered body having uniform and superior mechanical characteristics at the surface and central parts even in case of a large thickness can be manufactured.

Abstract: PURPOSE:To automatically stop an automatic machine and to produce an alarm to a worker by detecting the position of a plunger when the residual quantity of cream solder in a syringe attains the necessary minimum quantity by using a detector. CONSTITUTION:In the dispenser device 2, at a point of time of starting activity, the cream solder 8 is contained to the full in the syringe 4 and the plunger 10 is located at the upper part and separated from a magnetism detector 14. Accordingly, in this state, magnetism of a magnet 12 fitted to the plunger 10 is not detected by the magnetism detector 14 and a contact part is made in an open-circuit state. When application and consumption of the cream solder 8 are proceeded and the residual quantity thereof is made in a minimum state, the plunger 10 and the magnet 12 approach the magnetism detector 14 which detects the magnetism of the magnet 12 and the contact point part is made in a closed-circuit state. By this method, the automatic machine is stopped automatically and the alarm is produced to inform this state to the worker. As a result, the occurrence of a defective product on which the cream solder 8 is not applied is prevented.

CONSTITUTION: Concerning a tension guide lock 16, a little frictional force is applied so as to keep the strain state of an elastic band 13 against the pulling force of a feed dog 9. As shown by a reference figure 70, when it is necessary to crease a fabric, a driving roll 20 is operated at prescribed adjusted feeding speed lower than the pulling speed of the feed dog 9. At the same time, a piston rod 26, to which an elastic band pulling idler roll 25 is connected, is moved forward in the direction of an arrow 27 and the elastic band 13 is further pulled. The pulling quantity of the elastic band 13 is controlled by the rotating speed of the driving roll 20. After the elastic band pulled at a prescribed degree is sewn on a fabric piece 69, a worker performs a cutting process by pressing a foot control pedal.

Title: Waveform digitizer
Inventor: FUJITA TAKAO
IPC: G01R13/20
Filed: 1990-02-16
Abstract: PURPOSE:To correct the deterioration of a group-delay characteristic by storing the time series data which have undergone AD conversion through an anti- aliasing filter into a memory, reading the data in the reverse time series, making the data pass through the filter again, and performing AD conversion. CONSTITUTION:An anti-aliasing filter 2 outputs a signal wherein a frequency component of at least 1/2 of a sampling frequency fs is cut based on an input signal. The output signal becomes the output waveform having group-delay distortion. The digital data of the waveform are once stored in a memory 4. Then, a switch 6 is changed, and the digital data in the memory 4 are outputted so that the time series is reversed at the speed of the sampling rate of 1/fs. The signal undergoes DA conversion in a DA converter 5. The signal is inputted into the filter 2, and the group-delay distortion is corrected. The signal is digitalized in an AD converter 3. The data are stored in the memory 4 again. When the waveform is displayed, the data are read out in the reversed time series. In this way, the filter 2 is added without deteriorating the group- delay characteristic, and a waveform digitizer wherein aliasing problem is solved can be realized.
