Title: Method and device for measuring thickness of sheet-like object
Inventor: ISOZAKI KENJI
IPC: G01B11/06
Filed: 1982-05-01
Abstract: PURPOSE:To measure the thickness of a sheet-like object, by detecting the high or low intensity of the light owing to interference that appears in transmitted or reflected light when monochromatic light of variable wavelengths is irradiated to said object as a function of the wavelength. CONSTITUTION:When a prism 13 rotates continuously, the light irraidated to a film 6 is made into the monochromatic light of continuously varying wavelengths, and the angle signal E1 of a driving part 15 is the signal corresponding to the wavelength lambda thereof. On the other hand, when the monochromatic light 6 transmits through the film 6, the light is reflected partly by the front and rear surfaces of the film 6. Therefore, the transmittance thereof is changed by the interference phenomenon of the reflected light and the rectilinear light. If the wavelengths forming the adjacent crest and crest of the wave of the transmitted light when a prism 13 is rotated and the monochromatic light of continuously varying wavelengths is irradiated to the film 6 are designated as lambda1 and lambda2, the relation l=(1/2ncostheta).[1/(1/lambda1-1/lambda2)] holds, and if the refractive index (n) of the film and the incident angle theta of the light are beforehand determined, the thickness l of the film 6 is determined continuously from the E1 and the output E3 of an arithmetic part 19 by inputting of the signal E2 corresponding to the quantity of the light transmitted through the film 6.

Title: Temperature controller
Inventor: SUGIOKA HIROAKI
IPC: G05D23/19
Filed: 1989-03-27
Abstract: PURPOSE:To decrease the number of sensors and to redice the sensor attachment manhour by performing a prescribed computing operation with use of the temperature signal received from only a temperature sensor that is set near a specific position among those temperature control means. CONSTITUTION:A temperature controller contains the heaters H1 - H8 set vertically in an area 1 to undergo the temperature control, a temperature sensor 2 set near a specific heater H8, and a temperature controller 3 which totally controls the heaters H1 - H8. The controller 3 receives the temperature information (temperature signal) received from the sensor 2 and an arithmetic part 32 calculates the difference between the measured temperature and the set one. An output coefficient part 31 multiples the arithmetic result by each output ratio (output coefficient) and applies the multi-point output to each heater H to perform the total control of the temperatures of those heaters H. Thus it is not required to prepare the temperature sensors in number corresponding to the heaters H nor to prepare a controller. As a result, the number of sensors are decreased together with reduction of the sensor attachment manhour.

Title: Rotary polygon mirror type scanner
Inventor: NAIKI TOSHIO
IPC: H04N1/04
Filed: 1987-03-27
Abstract: PURPOSE:To sufficiently obtain a high picture quality having no variation of a reflecting point and having a uniform focus, by a device whose optical member and its arrangement, etc., are manufactured in a standardized procedure and to reduce the cost, by providing a specular surface faced in parallel to each reflecting surface of a rotary polygon mirror for scanning. CONSTITUTION:When a light beam 2 is projected to the center 0 of a rotary polygon mirror 4, the light beam 2 is reflected with an angle of reflection in accordance with a direction to the light beam 2 by a reflecting surface 4a of the rotary polygon mirror 4. On the other hand, a specular surface 11a which is parallel to the reflecting surface 4a, and also, which is in a position where a distance to the reflecting surface 4a is equal to a distance to the center O always holds a position relation by the same body-like movement with the rotary polygon mirror 4, receives a reflected light from the reflecting surface 4a, and turns it to the original reflecting surface 4a. The reflecting surface 4a reflects the light beam 2 from the specular surface 11a, in the radiation direction from the center O, therefore, the surface 4a is assumed as a surface where a reflecting point always exists in the center position O of the rotary polygon mirror 4, and the reflecting point is immobile. In such a way, a part whose focal shift is large is not generated, therefore, it becomes unnecessary to place an optical system with high accuracy, and the manufacture of an image forming device can be standardized and the cost can be reduced.

IPC: H04S7/00
Filed: 1992-02-26
Abstract: PURPOSE:To prevent a difference between a sound image localization position and an intrinsic one. CONSTITUTION:Level detectors 1a-4a detects the levels of input signals from (ch) 1-4, an arithmetic unit 5 searches the maximum value from the detected result, and outputs it to a coefficient control part 6, and the coefficient control part 6 outputs a coefficient corresponding to the maximum value, so that a compressing processing can be operated to the input signals from the (ch) 1-4 by the same level control amount by each coefficient multiplier 1c-4c. Then, the input signal from each (ch) 1-4 to which the compressing processing is operated by the coefficient multipliers 1c-4c, has the same level control amount, so that each R, L, C, and S output can be a signal in the same level. Thus, the difference between the sound image localization position and the original one can be reduced, and the sound image localization position can be faithful.

Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To secure a finer and better source contact and improve reliability. SOLUTION: A groove which has an oblique plane is made at a substrate, and besides two sidewalls are made, and a transistor is manufactured, making the most of these. In short, since the trench processing end is decided, using the double sidewall 62, a fine trench can be made, getting over the limit of lithography, and besides it is of planar structure, so the processing by photolithography is easy. Moreover, the oblique plane is preserved until trench formation, being covered with a second sidewall, and then the second sidewall is removed to expose the oblique plane, and the oblique plane is used as a source electrode 130 contact area, so the contact area increases, therefore the source contact resistance is reduced. Moreover by the existence of the oblique plane, the bore of the trench is large, and the burying of a source electrode 130 is easy.

Title: Method for sealing thermocouple for measuring temperature of casting mold copper plate
Inventor: NARA MASATOSHI
IPC: B22D11/16
Filed: 1985-04-11
Abstract: PURPOSE:To prevent a thermocouple from contacting with the water intruding into a holder and to improve heat transmission efficiency by putting copper powder into the bottom of the recess of a casting mold copper plate then inserting a liquid packing material therein and curing the packing material after inserting the thermocouple. CONSTITUTION:The copper powder 8 is put into the recess 1A of the casting mold copper plate 1 and liquid silicone rubber 9 is poured into the recess 1A. The plate 1 is thereafter attached to an inside wall 4A of a water box and the thermocouple 2 is inserted into the holder 3. The top end of the thermocouple 2 contacts with the bottom wall of the recess 1A by passing through the rubber 9 and the inside of the copper powder 8. The rubber 9 cures upon lapse of time and the thermocouple 2 is thereby held in the packed state. The contact of the cooling water which intrudes into the holder 3 through the clearance generated between the copper plate 1 and an O-ring 6 with the thermocouple 2 is thus obviated during casting. The heat from the plate 1 is transmitted with high transmission efficiency to the thermocouple 2 by the copper powder 8.

Filed: 1990-03-27
Abstract: PURPOSE:To select an optional color for a color of background picture by detecting the position of a contour of a major object based on a blur of the picture of the major object and filling the inside of the detected contour with a picture of the major object at still state. CONSTITUTION:A processing computer 4 fetches a picture of a model accelerated and vibrated and sent from a video camera 30 and a blur detection circuit 4a detects a blur. Moreover, a blur side ridge detection section 4b detects a side ridge of a picture having a blur to extract the contour of the model. Since a color of a car body and a color of a background differ, the RGB value at the contour is fluctuated without fail and the contour of the car body is traced by deleting a contour line of a maximum connected area subject to labelling. A picture synthesis section 4c synthesizes a picture 12 of the model picked up while not accelerated stored in the memory 8 and a background picture 10 picked up in advance. Thus, an object synthesis picture is obtained.
