Title: Method for reduced projection type alignment
Inventor: NAKAJIMA NAOTO
IPC: H01L21/027
Filed: 1985-04-12
Abstract: PURPOSE:To enhance the degree of alignment accuracy by a method wherein the image of the alignment pattern of a reticle and the alignment pattern of a wafer are brought into the state wherein they are not in the relation of image formation of a reducing lens while the reticle and the image of alignment pattern of the wafer are being maintained on the same plane surface, thereby enabling to reduce the mutual interference of the reticle and the wafer alignment pattern. CONSTITUTION:When an Ar<+> laser beam which is not sensitive to resist is projected on a wafer pattern, the image of the wafer pattern is image-formed on the side located farther than the surface of reticle due to longitudinal chromatic aberration. In this case, a mirror part 27 is provided on the reticle surface, and the image 30a of the wafer pattern is formed in the vacant space aparted as far as 8 4mm from the lower part of a reticle 4 by having the laser beam reflected by the mirror part 27. The space image 29a formed by the Fresnel pattern 28 is used as the image indicating the position of the reticle. Besides, the space image 29a of the reticle and the alignment pattern 26 of the wafer are brought into the state wherein they are not related with the image of a reducing lens 3 by forming the space image 29a using an He-Ne laser beam.

Title: Alternate bit control circuit
Inventor: KASUYA NAOAKI
IPC: G06F11/14
Filed: 1984-04-17
Abstract: PURPOSE:To obtain an alternate bit control circuit having high efficiency in a simpler way by replacing a chip corresponding to an error bit with a spare bit only when the second error is detected.

Title: Digital radiation monitor device
Inventor: SUZUKI SHIGERU
IPC: G01T1/16
Filed: 1988-03-30
Abstract: PURPOSE:To confirm the soundness of the monitor device while eliminating the need to fit a bug source by providing a function for setting a lower-limit warning set value below the lower-limit range of a measurement range. CONSTITUTION:The radiation detection signal from a digital radiation detector 1 is inputted to a measuring instrument 3. A control part 32 measures a radiation level and displays the result on a graphic display part 34 in bar and digitally. When the measured value of the radiation level is lower than the lower limit of the measurement range of the measuring instrument 3, the graphic display part 34 displays the measured value only digitally. If abnormality, e.g. a down scale is generated in the monitor device, the measured value is lower than the lower-limit warning set value, so its lower-limit warning output is sent out through a digital output part 36.

Filed: 1987-04-01
Abstract: PURPOSE:To eliminate the need for a waiting time in case of retransmission after collision by preparing a channel comprising plural carrier frequencies and selecting optionally the carrier frequency and the sent time optionally in sending a signal. CONSTITUTION:Terminal stations 10a-10p comprising small sized earth stations send a data signal to a large sized earth station being s hub station 20 via a satellite 30. The stations 10a-10p select one frequency among carrier frequencies f1-f5 of the channel when a data to be sent exists at random and send a burst signal in matching with the transmission time slot. Moreover, they receive a collision signal from the hub station 20 and when its own station sends a data to the time slot corresponding to the collisin signal, the station sends the data again. In case of data retransmission, the transmission carrier frequency is selected at random again and the transmission time is selected at random in the range of, e.g., 1-5 slots.

IPC: B65H11/00
Filed: 1989-03-29
Abstract: PURPOSE:To prevent dust from penetrating by attaching a cover, with a cap plate covering a paper sheet inserting port, to a box body free of rising and setting motion. CONSTITUTION:A slide table 18 is extracted to the outside of a box body 1, thereby prolonging the length of a surface guiding a paper sheet 3 which is inserted from the front of the box body 1. At this time, since the rotational floating end side of a cover 17 is supported by a projection 23, this cover 17 is maintained in a state of opening a paper sheet inserting port 10. In addition, the slide table 18 is housed in an inmost part of the box body 1 by being inserted. At this time, since the projection 23 slides on an inclined groove 24 and comes nearer to the vicinity of a slightly lower side of a fulcrum shaft 19, the cover 17 rotates downward with this fulcrum shaft 19 as a supporting point, closing the paper sheet inserting port 10. With this constitution, dust penetration into the paper sheet inserting port 10 from the upside can be prevented by the cover 17.
