Title: Alignment device
Inventor: TOTSUKA MASAO
IPC: G03F9/00
Filed: 1987-05-06
Abstract: PURPOSE:To constantly assure the positions of the first element by a method wherein the first reference to be the alignment index of the first element such as a reticle as well as the second reference to be the alignment index of the second element such as a wafer at specified relative position to the first refer ence are monitored. CONSTITUTION:A mercury 1 is used for a light source. A g-beam is selected from the beams emitted from the mercury lamp 1 to lead the beam into a main body through the intermediary of an optical fiber 3. The fiber 3 is fixed to enter the beam into an optical system irradiating a main body side reticle alignment mark (main body side RA mark) upward. The main body side RA mark and (reticle side RA mark existing at specified gap are transmission- irradiated with this beam to image-form respective RA marks on a CCD or an image-pick up tube 9. Any detected image is fed to a computer (image proces sor) 13 to be image-processed for detecting relative slips of respective RA marks. Through these procedures, the data are transmitted to a reticle stage driving system to correct the slip for making alignment of the reticle with the main body.

Filed: 1990-04-25
Abstract: PURPOSE:To detect an accurate sum signal by detecting a data part and shaping a high frequency data signal in the data part to generate a sum signal to be a groove crossing signal. CONSTITUTION:The output of a 2-divided photodetector 6 is inputted to a cumu lative amplifier 7 and a differential amplifier 8, a high frequency component to be a noise is cut out by an LPF 10, the noise-removed signal is converted into a binary signal by a waveform shaping circuit 11, and the binary signal is outputted as a difference signal 16. On the other hand, the output 14 of the cumulative amplifier 7 is converted into a binary groove crossing signal 15 through a sum signal processing circuit 9. The circuit 9 generates the groove crossing signal 15 to be an accurate binary signal from a signal to which a signal recorded in a medium is superposed. Consequently, the groove crossing signal to be used for detecting the relative position relation between a beam spot and the medium 5 and the relative speed of the medium 5 in the radius direction can be detected.

Title: Recovering method for carbon dioxide by fuel cell
Inventor: IKEDA KOJI
IPC: H01M8/04
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To increasing the concentration of CO2 so as to facilitate the separation and recovery by mixing O2 gas or one part of gas on an air electrode side with the fuel electrode side gas of a solid electrolyte fuel cell main body outlet thereby catalyst-oxidizing to form a gas made of CO2 , H2 O, and a small amount of N2 . SOLUTION: A required amount of O2 gas is added from an oxygen supply line 6 to outlet gas from a fuel supply line 5-connected fuel electrode side gas passage 3, CO and H2 contained together with CO2 and H2 O are converted into the CO2 and the H2 O by a catalyst reactor 7. As air rather than the O2 gas the minimum required amount of produced gas from an air electrode side gas passage 2 may be added via a line 12. The H2 O is separated in a cooling tower 9 via a heat exchanger 8 from gas after conversion by a catalyst. Since this exhaust gas contains dense CO2 and a small amount of or nearly no N2 , the CO2 is easily disposed of as a liquefied CO2 by compression or as clathrate dry ice, or is easily scavenged by a adsorption method, or a solution absorption method.

Filed: 1990-04-24
Abstract: PURPOSE:To attenuate an undesired ultralow frequency signal component of a 1st operational amplifier by increasing the feedback quantity of a mirror integrating circuit more than the negative feedback of the 1st operational amplifier in a DC region. CONSTITUTION:A 1st operational amplifier 12 acts like a noninverting amplifier to an input signal eS. Thus, a noninverting output is applied to a load 4. After an undersired ultralow signal component eA1 is detected and amplified by a mirror integrating circuit 30, the result is fed back to a noninverting input of the 1st operational amplifier 12. Thus, a feedback beta from ultralow frequencies to DC band is increased to reduce the overall gain. That is, the feedback quantity of the mirror integration circuit 30 is increased more than the feedback quantity of the 1st operational amplifier 12, the negative feedback is made deep, the undesired ultralow frequency signal component eA1 of the 1st operational amplifier 12 is remarkably attenuated and the stability is much improved.

CONSTITUTION:The material, which is obtained by distributing Sb oxide at 0.05-6wt.%, Te oxide at 0. 01-2wt.%, and each oxide of Sn, In, Cu, Mn at 0.05-5wt.% in Ag, is used as the core material, and an Ag alloy layer, which is obtained by adding more than two kinds of element among Sb, Te, Sn, In, Cu, Mn at 0.01-2wt.% in Ag, is formed in the periphery of the core, and an area ratio of the Ag alloy layer which occupies in the whole of a cross-sectional area of the compound material is set at 5-40%. In the case that a ratio of the Ag alloy layer is less than 5%, covering effect against the contact base material is reduced and while spot welding and brazing to the base material is hard, and in the case that a ratio of the Ag alloy layer exceeds 40%, quantity of the covering material is too much and a problem is generated in the contact characteristic, especially in the welding-proof property. Bonding strength of Ag itself against the contact base material and the base material can be thereby improved.

Abstract: PROBLEM TO BE SOLVED: To realize the new MODEM communication method providing inter- operation capability between a MODEM and a device realizing a busy state call reception notice service. SOLUTION: Upon the receipt of a busy state call reception notice attention signal tone corresponding to a 3rd party call reception call, a MODEM 102 generates a busy state call reception notice signal. A processor 106 receives the busy state call reception notice attention signal tone and sends other busy state call reception notice attention signal to a processor 108 via MODEMs 102, 104. The processor 108 sends the busy state call reception notice acknowledge signal to the processor 106 via both the MODEMs to reserve both the MODEMs. The communication between the MODEMs is stopped in this reserved state till the MODEM 104 receives a restart signal. When the call reception call by a 3rd party is finished, the processor 106 sends the restart signal and the MODEM 104 is released from the reserved state.
