Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To provide an exposure method which does not cause a focus error for the amount of the thickness of a lower pattern, without necessity to consider the relation between the layout of the lower sensor and the position of a focus sensor. SOLUTION: In the case of forming an upper pattern only on the lower pattern 2, using a scanning exposure system on the surface of a wafer where a difference in level exists by the lower pattern 2, dummy patterns 1 having the same height as the lower pattern 2 are arranged in the right and left positions of the lower pattern 2.

Filed: 1991-11-15
Abstract: PURPOSE:To eliminate mutual disturbance among plural tuners without disconnecting a tuner power source by automatically fixing the frequency of a slave screen tuner to a reception frequency not generating a mutual interference beat when a slave screen is turned off. CONSTITUTION:A TV signal is supplied to a tuner 3 for master screen and a tuner 4 for slave screen via a branching filter 2. When the master and slave screens are displayed, circuit isolation is improved by a filter and a booster, etc., and the mutual disturbance can be reduced. When slave screen display is turned off, a switch 8 is turned off, and no video and audio signal for slave screen is outputted from a video detector 9, however, the tuner 4 is set at an operating state. At this time, the local oscillation frequency of the tuner 4 is set to a high frequency not generating the mutual interference beat by a channel selection signal from a microcomputer 5A. Thereby, the mutual disturbance among the tuners can be prevented from occurring, and responsiveness when the slave screen is turned off can be accelerated.

Filed: 1989-11-17
Abstract: PURPOSE:To freely perform access to another area by another host even when a certain host preferentially uses a certain memory area by providing a control mechanism which can set an access inhibit area to a storage part. CONSTITUTION:A first host 102 or a second host 103 sets addresses respectively to inhibit area starting and inhibit area ending address comparison parts 104 and 105 and freely performs access to a data storage part 101 while maintaining a state storage part 106 in an active state. At such a time, when the second or first host part 103 or 102 puts in the address, with which the data storage part 101 is accessed, into the data input to be compared of the address comparison parts 104 and 105, an illegal access display signal generation part 107 generates an illegal access display signal. Accordingly, exclusive control is enabled between the plural hosts 102 and 103. Thus, even when a certain host 102 or 103 preferentially uses a certain memory area, the other host 103 or 102 can freely perform access to the other area.

Abstract: PURPOSE:To prevent mis-registration between two sheet materials by constituting the title device in such a manner that the sheet material having the higher rigidity of the two sheet materials is run while said sheet is brought into contact with a stage. CONSTITUTION:The two sheet materials 65, 67 which are different in rigidity are held superposed on each other and are run in this state on the stage 7. The two sheet materials 65, 67 are brought into pressurized contact with each other by rollers 58, 58' which roll in the direction intersecting with the traveling direction of the two sheet materials and the stage 7; in addition, the device is so constituted that the sheet material 65 having the higher rigidity of the two sheet materials is run in the state of maintaining the contact with the stage. The sheet material 65 having the higher rigidity is thus brought into contact with the stage 7 at the time when said material is brought into pressurized contact with the stage by the rollers 58, 58' and, therefore, the generation of such a deformation as to accumulate the repulsive force to induce the parting between said sheet material and the sheet material 67 having the lower rigidity is obviated. The generation of the mis-registration between the two sheet materials is thereby prevented.
