Title: Zoom lens
Inventor: ONO SHIYUUSUKE
IPC: G02B15/167
Filed: 1983-12-14
Abstract: PURPOSE:To reduce the number of lenses, and to reduce deterioration of a performance caused by a temperature variation by forming a plastic lens, whose one surface has a non-spherical shape, and a relay lens system constituted by containing said lens, so that a specified condition is satisfied. CONSTITUTION:A relay lens system having an image forming function is constituted of lenses L8-L12, and as for the lens L9 among them, the sixteenth surface of an image side is a plastic lens of a non-spherical shape, and a focal distance satisfies an expression I . Unless this condition is satisfied, a moving extent of an image forming surface by a temperature variation becomes larger than a depth of focus within a working temperature range of a zoom lens for a video camera, and its lens is not used practically. Also, with respect to a small number of lenses and a large aperture ratio, the non-spherical aberration can be corrected by leading in a non-spherical shape. Moreover, when the relay lens system satisfies expressions II-V, the aberration correction can be further advanced. In this way, the number of lenses is reduced, and deterioration of a performance caused by a temperature variation can be reduced.

Title: Input/output instruction cancelling system for multiwindow
Inventor: TOMINAGA HITOSHI
IPC: G06F3/048
Filed: 1990-09-05
Abstract: PURPOSE:To cancel an I/O instruction from another process and to attain communication with the process concerned by providing this I/O instruction cancelling system with a window identifier(ID) forming part and an I/O instruction canceling part for a storage part screen. CONSTITUTION:At the time of requiring the display of data on a screen 10, a host computer 5 specifies and requests an execution program to a cancel process 4 and transfers an execution program display request and a display sentence to a mail part 6. The process 4 obtains a window ID in using the screen 10 at present from a storage part 8 and requests a screen control part 1 to cancel an I/O instruction to/from the corresponding window. The control part 1 falsely responds abnormal end to the I/O instruction. An execution program aborts the I/O instruction. The mail part 6 writes a requested telegram in a mail box 7 and interrupts the program to inform the existence of the telegram. The program requests the mail box 7 to read out the telegram sent to the program itself and requests the control part 1 to display the read telegram. Thus, communication from other units is surely executed.

Title: Application of read/write memory in one-chip microcomputer
Inventor: MAENO YOSHIHIKO
IPC: G06F12/00
Filed: 1984-11-12
Abstract: PURPOSE:To improve the performance of a program by repeating such sequence that storage data is read out from a stack with use of a register and again stored at its original address of the stack after the digit is shifted and utilizing the invariable information part of data stored at the address of the stack for control. CONSTITUTION:The step of a subroutine call in a main program is set so as to be at an addresses within X'F0XX' to 'F7XX'. Now, when the subroutine is called after a processing A in the main program, it is necessary to cope with the return after a current program execution address is moved to the stack. Accordingly (PC)+1 obtained by adding one to contents of a program counter PC when it is called is moved to the stack. In order to apply the stack where (PC)+1 is stored for control, a read/write memory of one-chip microcomputer is efficiently utilized. Thus limits with respect to program contents and interruption processing are relaxed, and accordingly the performance of a program is improved.

Title: Automatic equalization system
Inventor: HASHIMOTO SHINJI
IPC: H04B3/06
Filed: 1990-09-10
Abstract: PURPOSE:To prevent deterioration in a reception data due to the rapid fluctuation of a line providing a function calculating and correcting a phase shift with the tap weight of a 2nd stage automatic equalizing section to the section and providing a function to prevent divergence to a 1st stage automatic equalizing section. CONSTITUTION:When the fluctuation of a phase (phase hit) takes place in a telephone circuit, since the correction speed of a filter characteristic of a 1st automatic equalizer 13 is set small, a 1st automatic equalizer 13 cannot follow to the fluctuation, and a 1st error in a 1st error signal outputted from a 1st error extraction circuit 15 is larger. In this case, a level discrimination circuit 17 sends an open command signal to a switch 16 to prevent the divergence of the 1st automatic equalizer 13 to open the switch 16, thereby stopping the correction by the 1st automatic equalizer 13. However, since a 2nd automatic equalizer 18 has a few tap number as 10 stages and its correction speed of the filter characteristic is large, the 2nd automatic equalizer 18 follows to the phase hit to minimize the deterioration in a received data.

Abstract: PROBLEM TO BE SOLVED: To allow an analog interactive system to utilize a resource used by a digital interactive system. SOLUTION: An ICAP application production section 1 produces an ICAP application and a multimedia and hypermedia information coding experts group MHEG application production section 7 produces an MHEG application. In the case of using a resource based on a common resource by the ICAP and MHEG, an ICAP header generation section 11 generates an ICAP header in order that the ICAP uses the resource used by the MHEG. A digital transmission line packetizing section 8 transmits this ICAP header by means of a stream of an MPEG section structure. Thus, the ICAP application at the receiver side can use a high resolution resource for the MHEG.

Abstract: PURPOSE:To increase the efficiency of measurement of the accuracy of stepping of a wafer stage and also to analyze factors affecting the accuracy of stepping. CONSTITUTION:Marks (72XP1, 72YP1, etc.) for LIA measurement are formed by exposure as pattern images of a reticle sequentially in shot areas ES1 to ES16 on a wafer W. As a first measurement, the position of the mark for LIA measurement in each shot area is detected in the sequence of the shot areas ES13 to ES4, for instance, and the coordinates of a wafer stage whereon the wafer W is set is monitored by a laser interferometer. As a second measurement, thereafter, the position of the mark for LIA measurement in each shot area is detected in the sequence different from that in the first, for instance, and the coordinates of the wafer stage are monitored by the laser interferometer. An error in stepping is determined on the basis of a difference between the results of the measurements of two times.

Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To synchronize plural local data bases in plural distributed computing systems. SOLUTION: When the change of the directory in a directory data base affecting at least one of plural local LAN data bases calls a LAN server synchronizing library and the affected data base is synchronized, the synchronization of a LAN and a distributed computing environment (DCE) directory is generated. A synchronizing system utilizes the directory data base coupled with each of the local data bases. A first order replica is coupled with the directory data base and this first order repliuca synchronizes each local data within the DCE with the directory data base. Further, a second order replica is coupled with the first order replica. This second order replica synchronizes at least a LAN server including plural computing systems and some selected data bases of each system with the directory data base.
