Title: Method for measuring etched amount
Inventor: TOMIKAWA MITSUHIRO
IPC: C30B33/00
Filed: 1987-12-07
Abstract: PURPOSE:To indirectly surely measure etched amount in a short time by forming an etching pattern on the surface of a silicon single crystalline plate with a masking material and measuring the amount of traveling of a shift pattern while performing anisotropic etching treatment. CONSTITUTION:An etching pattern 4 is formed by coating the surface of a silicon single crystalline plate 1 whose crystalline direction is made to a face (100) with a masking material 3. This pattern 4 is formed into an octagonal shape surrounded by both four sides 5 parallel to axes X <110> and shift sides 6 parallel to axes Y <100>. Then this single crystalline plate 1 is subjected to anisotropic etching treatment with alkali soln. and the above- mentioned pattern 4 part is worked so that is is regulated to prescribed thickness. In this case, linear shift patterns 7 positioned under the shift sides 6 are moved along the axes Y <100> directions according to the advancement of anisotropic etching. Etched amount in the direction of thickness of the single crystalline plate 1 proportional to the amount of traveling can be measured by measuring the moving amount.

Title: Coating apparatus
Inventor: SHIMIZU NOBUO
IPC: H01L21/027
Filed: 1990-11-16
Abstract: PURPOSE:To apply a resist uniformly and coat the surface of a substrate having counter bores, through holes, etc., and the bottoms of the counter bores and grooves with the resist uniformly by dropping a liquid to the surface of the substrate and revolving and rotating the substrate to spread the liquid by centrifugal force and coat the whole surface of the substrate. CONSTITUTION:A silicon substrate 8 is rotated on its axis by rotation of a planet gear 1 and further revolved round a spur gear 2 in the center by the rotation of a main shaft 9 and a part 6 which rotates the planet gear. That is, the resist 10 which is dropped on the surface of the silicon substrate 8 is spread to the outer circumference of the silicon substrate 8 by the centrifugal force of the rotation of the planet gear 1, and at the same time, all the resist 10 on the silicon substrate 8 is spread to the outer circumference against the main shaft 9 due to the centrifugal force of the rotation of the main shaft 9. In this case, the silicon substrate 8 setting system is so made as to hold the substrate in air by a silicon substrate supporting column 7. This is for the reason that the resist is need to be applied also to the back side at the same time since the resist flows out to the other side through the through holes in the case of applying resist only to one side.

Title: Sputtering device
Inventor: KURIYAMA NOBORU
IPC: C23C14/40
Filed: 1988-12-09
Abstract: PURPOSE:To effectively prevent the generation of an arc discharge on a grounded electrode by forming a high-frequency power source or a transmission line so that the voltages to be impressed on the respective targets belonging to the same group have a phase difference from one another. CONSTITUTION:The high-frequency voltage outputted from a high-frequency voltage generator OSC5 is transformed by a transformer Tr5 into the two high-frequency voltages having a phase difference of 180 deg. from each other, and the two high-frequency voltages are impressed on targets T5 and T6. A glow discharge is generated between the targets T5 and T6 by the phase difference between the targets T5 and T6 due to the phase difference between the two high-frequency voltages, and plasma P5 is produced. A glow discharge is also generated in the same way between targets T7 and T8, and plasma P6 is produced. Since there is a sufficient distance between the pair of targets T5 and T6 and the pair of targets T7 and T8, the plasma P5 and the plasma P6 are not interfered with each other. Accordingly, since the current flowing between grounded electrodes 10 and 21 is extremely low, the arc discharge from the grounded electrode and the sputtering vaporization are reduced.

IPC: G02B5/18
Filed: 1988-12-09
Abstract: PURPOSE:To suppress warp of the base plate of a grating element against the shrinkage of an ultraviolet curing resin due to secular change to the utmost by forming the base plate of polystyrene or polycyclohexyl methacrylate to a thickness which is >=20 times as thick as that of the ultraviolet curing resin. CONSTITUTION:In the course of a metallic mold producing process, an ultraviolet curing resin 3 is poured into recessed sections formed on the surface of a metallic mold in a resin curing process after the metallic mold 5 is produced from a master disk for surface-relief type diffraction grating by electroforming and a base plate 4 is pressed against the mold 5. While the base plate 4 is pressed, the resin 3 is cured by irradiating the resin 3 with ultraviolet rays and, after the resin 3 is cured, the base plate 4 is separated. Thus a copied surface-relief type diffraction grating is produced. The thickness of the base plate 4 is set to a thickness which is >=20 times as thick as that of the resin 3 cured by the ultraviolet rays in the resin curing process and, at the same time, the base plate 4 is formed polystyrene or polycyclohexyl methacrylate. Therefore, the base plate 4 can have a good moisture absorbing and birefringent properties and, as a result, warp of the base plate due to secular change can be suppressed to the utmost.

Abstract: PURPOSE:To transport a longitudinal extending object easily in fluid by forming the object from a portion having a smaller specific gravity than the liquid and a one having greater specific gravity. CONSTITUTION:A cable 5 has flexibility in its longitudinal direction, and that portion of cable 5 which accommodates an adjusting member A displaces upward when set in a watercoarse 1, while that position of the cable 5 which accommodates another adjusting member B displaces downward, to provides such a form as bent zigzagged in the plumb plane in the direction 15 of water stream. Therefore, the projection area of the cable 5 becomes greater to the water stream. Thereby the cable 6 is given a force acting alongside the water stream through utilization of that great fluid resistance force which is obtained by water. Accordingly a minor power is required of the motor to tract the cable 5 which is in connection with a robot 4, said power being also allowed to be zero.

Abstract: PURPOSE: To produce digital display of analog signals which fluctuates between the maximum voltage and the minimum voltage cyclically by installing a detector which determines the coefficient of fluctuation of signals between the detected maximum voltage and minimum voltage. CONSTITUTION: For example, a vehicle 10 comprises four wheels 12a-12d and respective wheels 12a-12d have velocity sensors 14a-14d like magnetic resistance sensors to measure the coefficient of fluctuation of magnetic fluxes at the time when an attached object like a teeth row.

At that time, the coefficient of fluctuation of the analog signals between the detected minimum voltage and maximum voltage are determined by coefficient of fluctuation detectors installed respectively in the converters 16a, 16d.  Then, limiting signals to fluctuate the ratios in a prescribed proportional relation with a previously determined ratio are generated.

Abstract: PROBLEM TO BE SOLVED: To enhanced the visual confirmability of a demarcation display area by providing the demarcation display area which indicates by a non-continuous display that a region shown by such a display is the end of a character entry area, on at least one end side of the character entry area formed between rules. SOLUTION: On both end sides of a character entry area 13, a demarcation display area 16 is formed which indicates by a non-continuous display that a region shown by such a display is the end of the character entry area 13. This demarcation display area 16 is formed of dots 17 shown at a position located between transverse rules 12. Consequently the display of the demarcation display area 16 emerges in the non-continuous gap part 16a and its flickering image is visually perceived with a sense of animation. Thus such a visual image is conspicuous compared to a simple and monotonous straight line.  When the head shakes or the eye-reaching level is diverted especially when the character is written, the flickering image is more intensely perceived and thus it turns out that such an image gives a higher area discerning effect to the aged with a deteriorated eyesight, compared with a meticulously demarcated rule or the like.
