Filed: 1982-03-25
Abstract: PURPOSE:To prepare Ar gas in a high recovery ratio, by returning Ar gas used for  washing and regenerating a nitrogen adsorbent and oxygen adsorbent to a rectifying  column of an air low temperature separation apparatus. CONSTITUTION:A mixed gas of Ar with O and N taken out of the upper rectifying  column 2 of a rectifying column 1 in a low temperature air separation apparatus is  heated in a heat exchanger 3, and pressurized in a compressor 4, introduced into the  first-stage adsorber (5a) of an adsorption apparatus 5 to adsorb and remove N2 in a  nitrogen adsorption cylinder (5a-MS). The gas is then passed through a pipe (6a) and  valve (7a) and introduced into an oxygen adsorption cylinder (5a-CS) to adsorb and  remove the O2 and give the aimed Ar gas. On the other hand, valves (8c) and (9c) of  the third adsorber (5c) after completing the adsorption stage are closed to open a  valve (11c) and reduce the pressure of the third adsorber (5c) to almost atmospheric  pressure. Thus, N and O adsorbed in the nitrogen and oxygen adsorption cylinders (5c- MS) and (5c-CS) are desorbed. A valve (7b) of the second adsorber (5b) after completing the desorption stage under reduced pressure is closed to feed O from the apparatus  1 through a valve 16, pipe 15 and valve 14 to the nitrogen adsorption cylinder (5c-MS)  to wash and regenerate the nitrogen adsorbent. The Ar is partially fed to the oxygen  adsorbent cylinder (5b-CS) to wash and regenerate the oxygen adsorbent, and the resultant gas is then introduced into the rectifying column 2.

Title: Signal processor
Inventor: KAWADA KAZUHIDE
IPC: G06F9/06
Filed: 1989-02-28
Abstract: PURPOSE:To obtain a compact and inexpensive signal processor which is free from the limitation of types of practicable processes by rewriting a program stored in a memory only when a specific instruction is carried out. CONSTITUTION:When the instruction code of a RAM 1 is rewritten, (n+m) clock pulses are applied to a shift clock terminal 9 and the addresses of the RAM 1 to be rewritten are inputted to the high-order (n) bits of a shift register 5 together with the write instruction codes inputted newly to the low-order (m) bits via a serial data terminal 10 synchronously with the application of clock pulses to the terminal 9. Then a HALT instruction is read out of the RAM 1 after a reset terminal 8 is set at 'H'. Thus the HALT instruction decoder output 19 is set at 'H' with an RSFF circuit 3 set respectively. Then both inputs of an AND date 7 are set at 'H' and the data is written into the RAM 1. Thus the instruction stored in a memory is rewritten when a signal processor is not actually performing a process and therefore no extension is required for the RAM 1. As a result, a compact and an inexpensive signal processor is obtained.

Abstract: PURPOSE:To provide a master station replacement method in which simultaneous multiple address frames are not generated at random when a new subscriber station having a larger address number than that of a current master station subscribes to the network. CONSTITUTION:Plural stations (A-C) connecting to a line 1 form the token passing bus system, the stations (A-C) give a token frame from the station C having a larger address number 19 to the station A having a smaller address number sequentially to form a logic ring, the station C having the largest address number 19 acts as a master station and the other stations (A-B) act as slave stations. The master station C uses a simultaneous multiple address frame to inform a specific timing to the slave stations (A-B), the slave stations (A-B) matches the synchronization with the simultaneous multiple address frame. When a station D having a larger address number 20 than that of the current master station C subscribes to the existing logic ring (A-C), the new subscribing station D becomes a master station at the 2nd undetection of the master station and the station B having an address number 18 being a 2nd largest umber next to that of the current master station C becomes a master station at a 3rd undetection of the master station.

Abstract: PROBLEM TO BE SOLVED: To realize a scanning probe microscope capable of extremely reducing effect of the thermal expansion or shrinkage of a sample even if the temperature sample is made variable. SOLUTION: A rectangular sample 11 is placed on sample holders 12a, 12b and cylindrical electrodes 13a, 13b are arranged on the sample holders 12a, 12b so as to hold the sample 11 therebetween.
