Title: Exposure process
Inventor: NONAKA MISAKO
IPC: G03F7/20
Filed: 1988-03-29
Abstract: PURPOSE:To form a resist pattern in an excellent sectional shape by a method wherein a substrate is coated with a resist of a high absorbance in an exposure wavelength region to be subjected to projection-expose by using laser beams while heating the bottom surface of the substrate and cooling down the top surface of the substrate. CONSTITUTION:An Si substrate 2 is coated with a resist 1 in high absorbance in exposure wavelength region e.g., a novolak based resist to be excimer laser reduction projection exposed while heating the bottom surface of the substrate 2 and blowing cold blast from the surface of the resist 1. Thus, the gradient of the exposure level and that of the thermal energy caused during the exposure process can be offset. Consequently, the gradient of the exposure energy and the resultantly made difference in thermal energy on the surface and rear surface of the resist 1 are eliminated to equalize the solubility constant. Through these procedures, a resist pattern in excellent sectional shape can be formed.

Title: Disc reproducing device
Inventor: YOSHIDA TADAO
IPC: G11B19/28
Filed: 1983-04-26
Abstract: PURPOSE:To make the rotating speed of a disc stable even with the missing of a signal by not using directly a detecting value of the maximum inverting interval in a reproducing signal but using the minimum value of a detected value of the maximum inverting intervals for a long period. CONSTITUTION:A reset counter 12 counts the clock number A in the inverting interval and latched to a latch circuit 14. Then, the maximum value in a prescribed period P1 of the value A is detected by a latch circuit 15 and a magnitude comparator circuit 16 and latched to a latch circuit 17. The minimum value of a count value C in a period P2 longer than the maximum value of the signal missing period to be considered by the period P1 or over is detected by a set latch circuit 20 and a comparator circuit 21, and a value E is latched to the circuit 22. Since the signl missing period is larger than 11Tc (channel lock time) normally, the value C is a measured count value of this period. Since the value E is the minimum value of the value C within the long period P2, when the period P2 is longer as above, the value E is a counted value of an edge interval of a synchronizing signal. Then, even if the missing of signal occurs, a motor 28 is controlled by using the missing period as the maximum inverting interval so that this period is reduced to 11Tc.

IPC: H05G1/30
Filed: 1980-05-30
Abstract: PURPOSE:To ensure a proper exposure time even when there are abnormally light and dark places by arranging a number of photoelectric detectors which detects the brightness of a phosphor screen and driving a photo-timer depending upon the average value of these output. CONSTITUTION:An X-ray irradiated from an X-ray tube 3 passes through a subject 4, exposes a film 6, and is converted into light by an image tube 7 behind it. A part of the output of the image tube 7 is taken out by a mirror 8 and detected by a number of photodetectors which scatter. The photocurrent of these photodetectors enters a compare circuit 18 and is compared with the voltage from a voltage setting device 25 with a width which is assumed in a normal photographic condition. When there is an abnormally light (dark) place, switches 29 and 30 are opened. As a result, the average value of the outputs from the photodetectors which detect normal light is output from an average value circuit 34 and these outputs are integrated by an integration circuit 36. When this integration value exceeds a specified value, a high voltage generator 2 is stopped.

Title: Method of vulcanizing piezo rubber sheet equipped with electrode
Inventor: OGURA KOJI
IPC: B29K105/24
Filed: 1986-03-31
Abstract: PURPOSE:To prevent the electric wave receiving sensitivity characteristics from deteriorating and the early stage deterioration due to overcure from occurring by a method wherein the surfaces of a semi-cured rubber sheet is covered with electrodes consisting of unvulcanized electrically-conductive rubber and then vulcanized so as to be made into an integral body. CONSTITUTION:Unvulcanized electrically-conductive rubber electrode sheets 2 and 2 are stuck to both surfaces of a semi-vulcanized piezo rubber sheet 1 so as to be fully vulcanized into a product. The product is excellent in electric wave receiving sensitivity which is the requisite for electric wave receiving element. This is because the fact that the air contained in the piezo rubber sheet 1 escapes from the surface of the rubber by expanding its volume due to the heat of semi-vulcanization performed on the rubber sheet 1 before the electrically- conductive rubber electrode sheets 2 are stuck to the rubber sheet 1 and dissipates to the atmosphere before the unvulcanized electrically-conductive rubber electrode sheets 2 and 2 are stuck to the surface of the rubber sheet 1 and that the strain and unevenness of the rubber sheet even existing before semi-vulcanization are eliminated by semi-vulcanization so as to smooth its surface and further that no drooping at the periphery of the sheet develops when the electrically-conductive rubber electrode sheets are stuck in the unvulcanized state and furthermore that neither thicker portion nor thinner portion develops in the electrode sheet and consequently the thickness of the electrode sheet is nearly uniform.

Title: Laser gyro
Inventor: MATSUDA HIROSHI
IPC: G01C19/00
Filed: 1985-04-08
Abstract: PURPOSE:To eliminate completely the return light from optical fiber loops to improve the stability of a laser by providing independently the optical fiber loop which the laser beam passes clockwise and the other optical fiber loop which it passes counterclockwise. CONSTITUTION:The laser beam from a semiconductor laser 12 is divided by a coupling part 13 and is made incident on one end of each of optical fiber loops 10 and 11. These laser beams pass the loop 11 counterclockwise and passes the loop 10 clockwise. Laser beams passing these loops are superposed in a coupling part 14. If a gyro is rotated on an axis perpendicular to the plane to generate an optical path different between said laser beams, laser beams superposed in the coupling part 14 interfere with each other, and intensities of light inputted to photodetectors 15 and 16 are changed by the quantity corresponding to the speed of rotation. As the result, the rotative angular speed is detected on a basis of outputs of photodetectors 15 and 16.
