Title: Mark detection system
Inventor: IMAI YUJI
IPC: G03F9/00
Filed: 1987-03-19
Abstract: PURPOSE:To enhance the alignment accuracy by a method wherein a change in the strength of an alignment signal with reference to the position coordinates of a stage is stored into a memory and the position of the stage is controlled on the basis of an output from the memory. CONSTITUTION:An alignment beam 1 scans an alignment mark on a wafer 108; when the beam 1 reaches an edge part of a mark 2, the scattered light is generated. This detection light and the direct light reach a space filter 6 via a lens 106 and a beam-slitter 101. Then, the scattered light which has passed through the filter 6 is converted into a digital signal by a photoelectric transduc er 7 and is then stored into a memory 113. This A/D conversion is executed synchronously with a position pulse which is generated by a laser interferometer 111 to calculate the position coordinates of a stage 109. As a result, when the stage 109 is scanned, a change in the strength of an alignment signal with reference to the position coordinates of the stage 109 is stored into a memory 113. Then, a CPU 115 calculates an alignment position on the basis of an output from the memory 113 and the position of the stage 109 is detected via a control ler 112.

Abstract: PURPOSE:To release the lock of each paper discharge bin to enable the use of the paper discharge bin and enable the security protection of documents by providing the function of releasing the lock of all paper discharge bins in the case of a paper discharging failure being generated in the paper discharge bin. CONSTITUTION:A printer controller 1 receives a printing job through a host interface 13. After rasterizing process, the controller 1 sends out a paper feeding command to a printer engine 8 through an engine interface 9 and delivers video data. When the printer engine 8 starts printing according to the video data, the controller 1 performs the transmission of data, the selection of a paper discharge tray and the lock setting of each paper discharge bin. In the case of a jam being caused during paper discharging action, the jam is settled by releasing the lock of all the paper discharge bins in the case of no jam detecting sensor existing at each paper discharge bin while releasing the lock of the paper discharge bin to which the jam is caused in the case of a jam detecting sensor existing at each paper discharge bin.

Figures 28 and 29 are connected to the bit line through the P region and n +  region respectively, and figure 30 is connected to a word line 30'. In the n + p + in +  hook structure, the positive pores are accumulated in the p +  region by making use the fact that both n +  and p +  regions are floating. Thus the electron is injected into the high resistance (i) layer from the n +  region to turn the floating n +  region into depleted region to secure an accumulation of the voltage information. The voltage information of the depleted n +  region is not erased by a reading.

Filed: 1985-03-29
Abstract: PURPOSE:To access always and correctly a video RAM by using a clock for a CPU and a clock for a CRTC and controlling the clock forming timing of the second clock forming circuit. CONSTITUTION:When a clock (e) for a CPU is supplied to an OR gate 25 and the phase difference phi of a clock (h) for a CRTC for the clock (e) for the CPU is within a 0.5 clock, the continuity of the clock of a AND gate output (j) gated by the second AND gate 26 is preserved as it is.

For that reason, the pulse width of a counter output (k) goes to be one clock or above, the generating timing of the clock (h) for the CRTC formed based upon the counter output (j) is delayed and further approaches by the phase of the clock (e) for the CPU.

Filed: 1991-03-29
Abstract: PURPOSE:To obtain coated granulated fertilizer capable of arbitrarily controlling elution of the fertilizer component by coating the granulated fertilizer with a film having organism decomposability and also changing thickness of the film. CONSTITUTION:Granulated fertilizer is coated with a film formed of the polyurethanelike substance. This substance is obtained by performing urethane reaction for both polyhydroxyl compd. constituted of one kind of wool grease recovered in the case of washing wool, lanolin, lanolin fatty acid or lanolin alcohol or the mixture thereof and polyisocyanate. Thickness of the film (degree of coating) is arbitrarily changed by forming this film on the surface of the granulated fertilizer in a multiplex state. The degree of elution is easily controlled thereby. Since this polyurethanelike substance has organism decomposability, trouble remaining and accumulating in the soil are solved by this film.
