Title: Shift register control system
Inventor: YAMADA TOSHIRO
IPC: H01L21/8234
Filed: 1985-05-17
Abstract: PURPOSE:To require no lowering of an operating frequency even when a shift register length is lengthened by asynchronously supplying clock enable signals to respective elements of the shift register by an inverter chain along directions from an output to an input of the shift register. CONSTITUTION:A wave form (e) is to be inputted to a control signal input section 101. In this case, at a time t1, a register 5 is operated, the data stored in the register 5 is transferred to an output 111, and then, at a time t2, the data stored in a register 4 is transferred to the register 5 and the data is successively transferred from the input to the output. The time in which the respective registers operate is shifted in time as indicated by t1, t2, t3..., and therefore, an instantaneous current can be reduced. A maximum operating frequency of a shift register control system depends only on the operating frequency of respective inverters constituting a controlling inverter chain and does not depend on the length of the shift register. Thereby, when the shift register becomes ling, the maximum operating frequency is not lowered.

Title: Manufacture of clathrate compound thin film
Inventor: KUROSHIMA SADANORI
IPC: C23C14/58
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To form a clathrate compound thin film on a substrate to enable to apply for devices by forming a vapor deposited film of an alkali metal on the group IV element substrate, heat-treating the substrate in a rare gas atmosphere and next, further heating in vacuum. SOLUTION: The vapor deposited film of the alkali metal such as sodium silicide is formed on the substrate of group IV element such as silicon. The substrate is heated in an inert gas atmosphere of about atmospheric pressure to form a compound of the alkali metal with the group IV element in the vicinity of the surface of the group IV element substrate so that the vapor deposited alkali metal is not released again from the substrate. Next, the substrate is heated again in the vacuum of about 10<-8> Torr. Then the structure of the compound of the alkali metal with the group IV element is reconstructed by releasing the alkali metal from the compound in the vicinity of the surface of the group IV element substrate to form a clathrate structure. Because the reaction occurs only in the vicinity of the substrate surface, the clathrate thin film including the alkali metal is obtained.

Abstract: PURPOSE:To attain effective utilization by efficiently removing H2S in high temp. gas while recovering elemental sulfur, by bringing H2S-containing gas into contact with composite metal oxide while regenerating said composite metal sulfide with SO2-containing gas. CONSTITUTION:Composite metal oxide XY2IIIO4 (wherein X is Zn, Fe, Mn or Cu and YII is Al or Cr) is used as an absorbent. H2S-containing gas is introduced into a first stage desulfurization tower 1 and a H2S-concn. is reduced to 1/3 by composite metal oxide. In the next step, residual H2S is removed in a second stage desulfurization tower 2 by metal oxide to exhaust as clean gas. Metal sulfide converted from metal oxide by the absorption of H2S is sent to a first stage regeneration tower 3 and regenerated by air while the regenerated metal oxide is returned to the desulfurization tower 2. The SO2-containing gas generated in this process is heated to 1,000-1,200 deg.C in a heating furnace 5 while heated gas is sent to a second stage regeneration tower 4 to regenerate composite metal sulfide converted from composite metal oxide by H2S-absorption. The generated gaseous sulfur is cooled in a sulfur recovery apparatus 6 to recover elemental sulfur.
