Title: Optical switch optical system for multi-wavelength spectroscope
Inventor: SAKAMAKI TAKESHI
IPC: G01J3/02
Filed: 1984-05-30
Abstract: PURPOSE:To allow laser beam to coincide with the optical axis of a multi-wavelength spectroscope, by inserting and connecting a beam transmitting element for transmitting laser beam between an optical switch and the multi-wavelength spectroscope. CONSTITUTION:The beam emitted from a beam source 1 is condensed and incident to one terminal of a bundled fiber 3 through a condensing lens system 2 and transmitted through an emitting fiber 5 from the other terminal of said fiber 3 through a beam measuring cell 4 and guided to an optical switch 6 from the other terminal of said fiber 5 branched into multiple channels. Said branched beams are changed over in time sharing by the switch 6 and taken out in a definite direction by mirrors M1, M2 and condensed by a condensing lens L1 to be formed into an image. Further, said beams are uniformized during the transmission through a fiber rod 9 and emitted from the other terminal 11 of the rod 9 positioned in the vicinity of the slit S of a multi-wavelength spectroscope 8 to reach a grating G. By this mechanism, if the emitting terminal surface of the rod 9 is coincided with an optical axis, all of laser beams of the channels of the fiber 5 can be coincided with the optical axis.

IPC: H01L21/302
Filed: 1989-04-27
Abstract: PURPOSE:To enable an actual etching terminal to be detected accurately thereby enabling the optimum etching process to be performed by a method wherein the difference between the latest sampled lighting intensity and the lighting intensity sampled before the specified period is measured while the latest sampling is judged to be the etching terminal subjected to the coincidence of difference in the lighting intensity with the set up value and so forth. CONSTITUTION:The lighting intensity (b) of specific processing light emitted during etching process is sampled per specified sample period T so as to measure the difference between the latest lighting intensity and that sampled before the specified period. Then, the latest sampling in the preceding period is judged to be the etching terminal T2 subjected to the coincidence of the difference in the lighting intensity with the previously set up value (e) so that the said etching process may be terminated at the T3 after the lapse of overetching (f) for specific term from the etching terminal T2. For example, a vacuum chamber 1 wherein a substrate 3 is etched is fitted with a photoelectric converter 5 provided with a spectrofilter 4 so that the voltage signal from the converter 5 may be converted into digital voltage signal V to be transmitted to a microcomputer 7 for controlling the etching process as mentioned above.

Title: Shift operation mechanism for speed change gear
Inventor: MURAMATSU MICHIYASU
IPC: F16H63/34
Filed: 1985-05-21
Abstract: PURPOSE:To simplify the structure by making a shift stroke slip by the amount of shift in which a small amount of shift is subtracted from the shift amount of a shift actuator in a shift shaft having a small amount of shift so that the difference in the shift can be absorbed. CONSTITUTION:Shift shafts 2 through 5 have shift forks 2A through 5A respectively, and the shift shaft 5 has a bracket 53 intervening a spring 51. When a speed change gear ratio is commanded, an actuator comes to a state in which a piston rod 11 is most retracted, and a shift shaft 5 is selected. When the shift shaft 5 moves, the bracket 53 begins to compress the spring 51 to move the shift fork 5A, and a reverse gear engagement is realized. Thus, the shifting of plural number of shift shafts each of which has a different amount of shift can be enabled by a single shift actuator.

Abstract: PURPOSE:To save product cost and construction cost by using both of DC and AC coils as an induction heating means, providing a selector device for selecting output from both of the aforesaid coils, and feeding back the operation mode of a roll rotational speed detector and the signal thereof to the selector device. CONSTITUTION:A rotational speed detector 21 always detects the speed of a rotary roll 1 and transmits a rotational speed signal 22 to a feedback device 23. This feedback device 23 compares the signal 22 with a rotational speed lower limit value 24 set with a heating control device 10. When the level of the rotational speed signal 22 from the rotational speed detector 21 drops to or below the aforesaid lower limit value 24, a rotational speed drop signal 18 is outputted from the feedback device 23 to selector devices 25a to 25n. Then, the selector devices 25a to 25n fix DC heating instruction signals 9a to 9n at maximum levels, and gradually increase the levels of AC heating instruction signals 20a to 20n. As a result, induction heating due to AC oils 11a to 11n in addition to DC coils 6a to 6n starts, and the heating deficiency of the DC coils 6a to 6n is thereby compensated. According to the aforesaid construction, product cost and construction cost can be saved.

Abstract: PURPOSE: To realize the conversion of the COD component contained in the raw sewage into the BOD component which can be applied effectively and increase the T-N elimination rate in the primary treatment, by exposing the raw sewage to air via the exhausted ozone gas after the ozone treatment in the tertiary treatment.  
     CONSTITUTION: The raw sewage U is sent to the 1st denitrification bath D 1  via the bath U 1  and then diluted by the water after the denitrification to be sent to the nitrification bath N after an adjustment applied to the BOD concentration. Then the part of the nitrified solution NL is circulated, and at the same time the residual nitrified solution is sent to the 2nd denitrification bath D 2 . Here no addition of the methanol is required for the bath D 2  as the BOD source since the nitrogen elimination factor is high in the primary treatment. After this, the treated water undergoes the treatments for the precipitation C and the filter F each and then the ozone treatment O to receive the decoloring and the elimination of the COD each. The exhausted ozone gas O' is sent back to the raw sewage adjustment bath U 1  to convert the COD in the raw sewage into the BOD. In such way, both the methanol and the re-deration tank can be eliminated, and then the exhausted ozone can be applied effectively.

Title: Pasteurizable and freeze driable hemoglobin-base substitute blood
Inventor: JIEN CHIYAN SHIA
IPC: A61K38/16
Filed: 1988-05-06
Abstract: The present specification describes a process by which a blood substitute (hereinafter referred to as "HemoSafe") is derived from uniformly stabilized monomers and polymers of deoxyhemoglobin in its tight (T) conformation, with oxygen affinity similar to that of human blood. Two classes of HemoSafe are derived respectively from animal-hemoglobin and human-hemoglobin. HemoSafe (animal) differs from HemoSafe (human) in that it is free of polymers in order to reduce potential immunogenicity if used in man. Both types of HemoSafe may be derived in the following manner. The stabilized deoxyhemoglobins are converted to their carbonmonoxy derivatives (CO-HemoSafe) which are then stable under pasteurization conditions to render them viral disease transmission-free. CO-HemoSafes are stable for 2 months at 56 DEG C in either the solution or the freeze-dried state. For transfusion CO-HemoSafes are easily oxygenated under sterile conditions by photoconversion yielding oxy-HemoSafe. In addition a transfusable met-hemoglobin derivative for treatment of cyanide poisoning, is derived by converting oxy-HemoSafe to met-HemoSafe.
