Title: Camera distortion measuring instrument
Inventor: HIZUKA TAKASHI
IPC: G01B11/24
Filed: 1988-03-01
Abstract: PURPOSE:To measure camera distortion with high accuracy by multiplying the deformed grating image outputted by a camera by a reference grating pattern and generating two moire fringes which have a necessary phase difference, and detecting the distortion according to the addition image. CONSTITUTION:The reference grating pattern is projected on a body by a projector 31 and picked up by the television camera 32, whose output is inputted to a multiplier 37. A multiplier 37 multiplies its by a grating pattern equivalent to said reference grating pattern outputted by a grating pattern generator 35. Further, a multiplying means 38 multiplies the grating pattern from the grating pattern generator 35 by a pattern which is shifted in phase by a phase shifter 36 and said picked-up pattern. The outputs of the multipliers are processed into moire fringes which are set to a reference phase and moire fringes which are shifted in phase by a specific value and they are added by an adder 43. A movement direction detecting means 44 detects the movement direction of the moire fringes according to the addition output. The moire fringes whose movement direction is detected are processed by a line thinning processing means 441 and a quantity detection processing part 442 detects distortion on picture elements.

Title: Liquid crystal display
Inventor: SUGIHARA KENICHIRO
IPC: G02F1/1335
Filed: 1986-03-07
Abstract: PURPOSE:To obtain display having high degree of sharpness by providing a Magenta, Cyan, and Yellow color polarizing plate to the exiting light side and inclining each color polarizing plate at each specified angle to each axis of polarization of the polarizing plate at the incident light side so as to obtain the minimum transmittance for each color. CONSTITUTION:When an electric voltage is not impressed to transparent electrodes 2, 2', the axis of polarization of the incident light which is transformed to linearly polarized light toward an arrow mark (a) by a polarizing plate 3 is twisted by 90 deg. when the incident light transmits a liquid cell L. Components of corresponding wavelength are absorbed by the polarizing plates 3M, 3C, and 3Y so as to obtain the max. absorption of Magenta, Cyan, and Yellow color, so the transmittance of the incident light becomes minimum as a whole, when it exits through the polarizing plate 3Y. On the other hand, when electric field generated by an electric power source E is impressed to liquid crystal between the transparent electrodes 2, 2', the molecular axis of the liquid crystal l is inclined along the direction of the electric field, so the incident light exits as it is through the liquid crystal cell L, but transmits without being shielded by the polarizing plates 3M, 3C, and 3Y. Thus, negative display having high sharpness and high contrast is obtd.

Inventor: AOYAMA MASAYOSHI
IPC: C22F1/00
Filed: 1993-02-15
Abstract: PURPOSE:To improve the tensile strength of a copper alloy wire without deteriorating its electric conductivity and to improve its productivity by continuous casting by adding specified amount of Mg, In and Sn to Cu in which the content of oxygen is specified, subjecting it to cold wire drawing and thereafter executing annealing. CONSTITUTION:In a continuous casting device, the reducing degree of a reducing atmosphere is controlled to regulate the oxygen content in molten copper into <=50ppm.

Title: Rotating drum device and its production
Inventor: OKAZAKI MASANORI
IPC: G11B5/53
Filed: 1993-02-15
Abstract: PURPOSE:To prevent the loss of driving power without increasing friction force even if the front end of a head wears by notching the rear surface side of a work to form a recessed part, cutting a front surface side and forming a projecting part on the front surface side integrally with a middle drum. CONSTITUTION:The rear surface side of the work 30 is notched to form a recessed part 30b and the front surface side is cut by a cutting tool 40. Cutting resistance is generated according to the cutting direction and cutting force at the time of this cutting and the force perpendicular to the front surface 30a of the work 30 acts thereon. The part near the center on the recessed part 30b side is then strongly pressed and deflected. This recessed part 30b restores the original shape after the working, by which the projecting part 33 of nearly the same height as the projecting height of a magnetic head 31 is integrally formed on the front surface side. Since the projecting part 33 is formed integrally on the middle drum 14 in such a manner, the increase in the friction force by contact of the surface of the middle drum 14 with a magnetic tape is prevented by the projecting part 33 even if the top end of the head 31 is slightly worn after relatively long-term use according to the rotary drum device. The loss of the friction force at the time of allowing the tape to travel is thus prevented.

Title: Photomask
Inventor: HOUKOU MORIHISA
IPC: G03F1/00
Filed: 1984-03-16
Abstract: PURPOSE:To expose >=2 kinds of patterns only by one photomask to reduce the number of photomasks by forming different photomask patterns on the same transparent substrate by different plural light shielding films to constitute the photomask. CONSTITUTION:The photomask 1 has an approximately square transparent substrate 2 consisting of quartz or the like and mask patterns are formed on the surface of the substrate 2 by the light shielding film 3. As shown in a section cut by the line II-II, the light shielding film 3 is constituted of two kinds of light shielding films 4, 5 having different light shielding characteristics each other and the light shielding films 4, 5 form required mask patterns independently. Therefore, the light shielding films 4, 5 are formed on different positions or in a superposed state on the transparent substrate 2. For instance, a film similar to an interference filter obtained by forming a thin film of silver or other substances and a film such as a crome film interrupting the transmission of light are applied as the light shielding films 4, 5 respectively. Since two kinds or more of patterns can be exposed only by one photomask, the number of photomasks can be reduced as compared to the number of necessary patterns and the working efficiency and the yield of production can be improved.
