Title: Light source device of colorimeter
Inventor: TAKADA NAOYA
IPC: G01J3/10
Filed: 1988-04-28
Abstract: PURPOSE:To exhibit stable diffusibility over a long period of time by forming the inside of the peripheral wall of a light diffusion chamber of fluoroplastic. CONSTITUTION:Light from a light source 1 is diffused into the light diffusion chamber 32 to eliminate the spectral distribution and the change in the quantity of light of a xenon tube. This light is used for projection. The diffusion chamber 32 is formed of the fluoroplastic. The fluoroplastic resin itself is white and has diffusibility so that the light from the light source can be sufficiently diffused and used for projection without entailing ancillary operations of painting, etc. The fluoroplastic is an inert material, has good stability and is not deteriorated in properties and discolored even by the thermal influence from the light source 1. The diffusibility stable over a long period of time is, therefore, maintained without repainting and exchanging. The reliability of the color measurement of the colorimeter is thus improved.

Filed: 1984-05-28
Abstract: PURPOSE:To simplify structure, and to utilize an element surface effectively by providing a switching means through which one conduction type semiconductor region, potential thereof must be returned at an opportune time, and an element isolation region are brought to a conductive state at the opportune time. CONSTITUTION:When reading pulse voltage VR is applied for a fixed time and polysilicon 14 is brought to ground potential, a p-base region 9 is brought to a reverse bias state to an n<+> emitter region 15, the change of potential of the n<+> emitter region 15 stops, and informations on the emitter side are read to the outside through polysilicon 13 and an electrode 19. When reading is completed, the electrode 19 is grounded, and the n<+> emitter region 15 is brought to ground potential, but optical informations must be eliminated because the potential of the p-base region 9 corresponds to the intensity of light under the state. Accordingly, when negative pulse voltage VRH exceeding the threshold voltage Vth of a p-MOS transistor is applied to polysilicon 14 through an electrode 17, the p- MOS transistor is brought to a conductive state, holes stored in the p-base region 9 are removed, and the potential of the p-base region 9 is fixed at predetermined negative voltage applied to a p<+> element isolation region 6.

Abstract: PURPOSE:To improve the characteristic of a p channel TFT and to form a high-speed circuit by oxidizing a non-single crystal silicon thin film on an insulat ing substrate to form the channel region of the (p) channel and (n) channel thin-film transistors. CONSTITUTION:Non-single crystal silicon thin films 4P and 4N are heat-treated in an oxidizing atmosphere to reduce the defects in a polycrystal silicon thin film to form the channel region of a TFT. In this case, the (n) channel TFT has an optimum content of oxide, and the TFT characteristic is conversely deteriorated above that content. Meanwhile, the characteristic of the (p) channel TFT is further improved even if the (n) channel TFT is oxidized in the larger amt. than optimum. Further, the oxide content of the non-single crystal silicon thin film 4P constituting the (p) channel is made higher than that of the non- single crystal silicon thin film constituting the (p)channel TFT. Consequently, the defects of the non-single crystal silicon thin films 4N and 4P are reduced in the (p) channel TFT and (u)channel TFT.

IPC: B21B38/00
Filed: 1980-08-05
Abstract: PURPOSE:To detect traveling speed accurately and improve qualiy of a steel plate by raising a measuring roll after the tip of a steel plate passed and at the same time making it free run state. CONSTITUTION:When the tip of a steel plate 12 comes out from a finishing rolling mill 10 and sent to a hot run table 14, the tip of the steel plate 12 is detected by an HMD44. Simultaneously with generation of this detection signal, output pulse operation of a pulse generator 24 is started. The speed of the steel plate 12 is determined by correcting the detected speed of the pulse generator 24 using a fixed advance ratio. After the steel plate 12 passed a measuring roll 28, an elevator 40 is actuated to raise the roll 28 by specified amount and it is made free run state. By this operation, the roll 28 rotates without causing slipping with the steel plate 12, and converts traveling speed of the steel plate into rotation speed of the roll 18. Thus, the roll 28 detects the traveling speed of the steel plate correctly and makes correction according to the output of the pulse generator 24.

Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To make accurate measurements of the pupillary distance and the inclination of the face by reducing the influence of the movement of the eye to be examined on such measurements. SOLUTION: To measure the pupillary distance, a measuring part 4 is first aligned with one eye and the horizontal position of the measuring part 4 is recorded by means of a potentiometer 5. Next, the measuring part 4 is moved horizontally by an average pupillary distance of 63 mm toward the other eye. An image signal of the picture obtained is sampled into a computing means so as to compute and recognize the center position of the pupil. The direction of a visual line is checked from the positional relationship between a cornea-reflected image and the pupil, and when the visual line deviates from a measuring optical path O1, a distance of the center of rotation of 13 mm for the average eyeball is used to compute the position of the pupil when the visual line is aligned with the optical path O1.  The pupillary distance of the eyes E to be examined is then determined from the positions of the pupils within a screen and an average pupillary distance of 63 mm, and a difference in height between the right and left pupils is determined from a difference in height within the screen between the eyes E to be examined. The inclination of the face is calculated form the pupillary distance and the difference in height between the right and left eyes and the angle of astigmatism is measured on the basis of the distance connecting the right and left pupils.
