Inventor: SETO HIROMITSU
IPC: G11B27/10
Filed: 1993-02-18
Abstract: PURPOSE:To decentralize an identification number issuing processing by imparting an identification number for every prescribed group and to facilitate an issuing number by facilitating the management of a free number. CONSTITUTION:By the instruction of a control part 10, a device number issuing number part 60 issues the hierarchical group number (first stage group number) every file part 15 corresponding to a file part 15N and this is written in the buffer memory of the part 10. Further, a file part inside number issuing number part 20 issues the minimum free number (second hierarchical group number) within the part 15 to which a storage medium 55 belongs as the identification number of this storage medium. Thus, the first and second hierarchical group are issued, and the identification number of the medium 55 is written in the medium 55 by a writing device 22. Thus, as a prescribed identification number is allocated to the storage medium for every prescribed hierarchy, the processing on the issuing number of the identification number is decentralized. The management of the free number of the free number is facilitated, and retrieval speed is also improved.

Title: Method for preparing oxygen by adsorption
Inventor: REON EI
IPC: B01D53/047
Filed: 1992-02-17
Abstract: PURPOSE: To remove the regulation of the actual number of tons on oxygen produced per unit by appropriately combining the number of adsorbers, the maximum speed of gas passing through the adsorbers and pumping continuation time.  
     CONSTITUTION: The number of zeolite adsorbers is set to be three. The maximum speed of gas passing through the adsorbers is made to be smaller than the friction speed of an adsorbent at any instance of a cycle and is approximated to the limit during at least one stage of the cycle. In the pumping stage of continuation time where a countercurrent pressure reducing operation is executed at pressure lower than atmosphere, pumping continuation time is set to be longer than a phase difference and to be equal to at least manufacture stage continuation time. The pumping period of the adsorber is executed by sequentially using two pumping devices for the adsorber. One pumping device operates from the beginning of pumping and the other operates until pumping is over. Air is periodically supplied from one adsorber to the next adsorber by shifting time. Thus, gas rich in oxygen is obtained by adsorption of nitrogen.

Filed: 1988-02-10
Abstract: PURPOSE:To enable a dummy operation of dispensing resist solution to be carried out automatically, by programming such that one dummy operation of dispensing resist solution which has been deteriorated is carried out automatically if the resist solution has not been dropped for a period of time longer than a set time though the dropping is possible. CONSTITUTION:It is previously determined, through a time setting section 71, after how many seconds since cease of a carry ready signal the dummy dispense operation is to be started. The number of seconds thus set is counted down by a counter 72 from the instance the carry ready signal ceases. A CPU 70 detects from output of the counter 72 the fact that the set time has elaspsed. The dummy dispense operation is performed in the following way. A scanner 31 is first driven by control of the CPU 70 so that a resist nozzle 30 placed at the position opposed to the center of a chuck 10 is moved to a position deviated from the chuck 10. A bellows pump 33 is then driven so that a predetermined amount of resist is dispensed from the tip end of the nozzle 30. In this manner, the dummy dispense operation can be carried out in a simplified manner.

Title: Method and device for measuring temperature of semiconductor substrate
Inventor: CHIBA TAKATOSHI
IPC: G01K11/12
Filed: 1987-02-12
Abstract: PURPOSE:To measure temperature without contaminating a wafer nor limiting a temperature measurement range by projecting light for temperature measurement on the surface on the wafer and detecting the base absorption end wavelength of the wave that transmitted light contains, and thus finding the temperature. CONSTITUTION:The wafer 5 placed in a heat treating furnace 2 made of quartz glass is heated by a light source 3 for heating. The light of a light source 7 for temperature measurement which is converged through a concave mirror 8 is intermitted by a mechanical chopper 9 and projected on the wafer 5 through an optical fiber 10 and a lens 11. Its transmitted light is incident on the spectroscope 15 of a base absorption end wavelength detection part M through a lens 12, an optical fiber 13, and a lens 14. The detection part M removes the influence of disturbing light due to a light source 3 for heating and detects the base absorption end wavelength lambda0 which is in inverse proportion to the inhibition band width Eg of the wafer 5. This lambda0 shifts to a longer-wavelength side as the temperature of the substrate rises, so the temperature can be measured without contacting. Consequently, the wafer is never contaminated. Further, the temperature measurement range is not limited unlike temperature measurement by radiant energy.
