Title: Production of optical element
Inventor: OHASHI ICHIJI
IPC: G02B5/18
Filed: 1994-12-12
Abstract: PURPOSE: To provide a process for production capable of efficiently and rapidly producing relief type diffraction optical elements having a high diffraction efficiency. CONSTITUTION: This process includes a stage for curving a base plate 3 at a prescribed curvature and a stage for forming relief patterns having a straight sectional shape on the curved surface of the base plate 3. For example, the base plate 3 having elasticity is held along the curved surface of a receiving member 4 having the curved surface 5 of a prescribed radius of curvature and is cut by a cutting tool 6 of which the moving locus at the time of cutting consists of a straight element. The base plate 3 is used as at least a part of the optical element. The oblique side part of a rectilinearly cut saw tooth shape constitutes a curve having the radius of curvature approximately at the time of curving if the base plate 3 is cut rectilinearly in the curved state and this state is released, i.e., the original shape is restored.  The movement of the cutting tool 6 is rectilinear, working data is simple and the speed of cutting with the cutting tool is high; nevertheless, the sectional shape of the resulted relief pattern is ideal.

Title: Exposure method and exposure mask
Inventor: OKI HIROYUKI
IPC: G03F1/00
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To make the absorbing quantity of exposure light of a resist film uniform regardless of the thickness of the resist film by exposing the resist film to a different quantity of light whenever the thickness of the resist film changes and to improve the dimensional accuracy of exposure and lithography without lowering the resolution of the resist film nor increasing the number of processes. SOLUTION: When a resist film 11 is exposed to a pattern, a first exposed section 11a having a film thickness t1 and a second exposed section 11b having another film thickness t2 are exposed with different quantities of light so that the ratio of the quantity of exposure light to their necessary minimum quantities of exposure light can become equal over the entire surface of the film 11. The exposure mask 2 used for the exposure has a light transmittance adjusting pattern 23 corresponding to the part which transmits the exposure light projected upon the first section 11a having a necessary minimum quantity of exposure light which is smaller than those of the other sections.  The pattern 23 has such a film thickness T that can reduce the initial quantity of exposure light so that the ratio of the quantity of exposure light to the first section 11a to the necessary minimum quantity of exposure light to the section 11a can become equal to the ratio at the second section 11b.

Title: Dummy target signal generating device
Inventor: WATANABE MASAHIRO
IPC: G01S7/40
Filed: 1988-12-06
Abstract: PURPOSE:To simplify the constitution by changing the position of an address where the information of a sent signal is written in every cycle of a smoothing clock signal determined by the speed of a dummy target. CONSTITUTION:The reference signal from a reference signal generation part 1 is inputted to a phase adjustment part 2 and put in phase with the sent signal (c) and a frequency division part 3 converts the frequency of the reference signal to low frequency; and a speed counter part 4 receives a speed information signal (a) and generates the smoothing clock signal 7 at intervals of time corresponding to distance resolution to its speed. This signal 7 is inputted to a storage part 6 and the position of the address of a RAM where the information of the signal (c) is written is changed in each cycle of the signal 7. Then a distance information signal (b) is inputted to a range delay part 5 to determine a delay time and an address position is determined to write the information of the signal (c). Thus, the address position is changed in each cycle of the signal 7, so a dummy target signal 8 is freely variable in delay time as to the signal (c).

Filed: 1990-11-16
Abstract: PURPOSE:To improve the reliability of a work business processing system in the most prior order by separating a device when it is judged that the work business processing system in the most prior order is not turned to a threshold dividing state even in the case of separating the device. CONSTITUTION:When requesting separation to the device concerning the throughput of the information processing system of a host 1, the host 1 recognizes the number of active devices concerning the throughput by a means 16 referring to a device number table 15 concerning the throughput of the information processing system existent in the host 1 and predicts the number of devices concerning the throughput of the information processing system after separating the device. Next, the threshold value of the work business processing system 11 at the most preference order in the host itself is recognized by a means 14 referring to a threshold value table 13 of each work business processing system, and the threshold value is compared with the predicative number of devices concerning the throughput of the information processing system after separating the device. When the threshold value of the system 11 is '3' and the predicative number after separating the device is '4', the device is separated since the system 11 at the most prior order is not turned to the threshold value dividing state by separating the device. Thus, the reliability of the work business processing system at the most prior order is improved.

CONSTITUTION:When a voltage at an AGC terminal 5 is decreased, a base voltage (the same as emitter voltage of an AGC driver Q1) of a switching TR Q3 is decreased and a current flowing to a 2nd bias circuit R7 is decreased. Finally, the base voltage of a switching TR Q3 is 5V, the same voltage as that at a DC power terminal 6 and the switching TR Q3 is turned off. The voltage applied to the AGC terminal 5 is varied with the input signal in this way and the switching TR Q3 is turned on/off depending on the voltage. Then the 2nd bias circuit R7 is turned on/off. Thus, the high frequency device ensuring sufficient attenuation with less loss is realized.

Filed: 1989-11-30
Abstract: PURPOSE:To reduce the backup data quantity of a data base by preserving data in a prescribed data unit, which includes an updating part, in a file as backup data at the time of executing a data base updating processing. CONSTITUTION:A backup file generation mechanism 17 generates the backup files 14-1 and 14-2 where data of a block including the updating part is stored as backup data before the updating processing by a data base updating mechanism 12 is terminated and data is outputted to the data base 11.

When two backup files of the same block, which are the present file and the file one generation before, a backup control mechanism 18 eliminates the backup file 13 which is one generation before. Since only data of the block including the updating part is stored in the backup fuel as backup data, the backup data quantity is reduced.
