Title: Photosensitive composition
Inventor: KURIYAMA SATOSHI
IPC: C09B11/00
Filed: 1983-05-12
Abstract: PURPOSE:To obtain a uniform yellow-orange color picture image having a stable color density for a long time by using a compd. which develops color by the light having a specified wavelength and a compd. which forms a carbonyl compd. by the light having separate wavelength as essential components. CONSTITUTION:[Bis(4-hydroxyphenyl)-(4-phosphonoylphenyl]methane (MHPM) expressed by the formula (wherein R1<1> is H, 1-18C alkyl, 2-18C alkenyl, aryl or aralkyl; R2<2> and R3<3> are 1-18C alkyl, 2-18C alkenyl, aryl or aralkyl) which develops color by the irradiation with the light L1 having a specified wavelength, is mixed with a compd. which forms a carbonyl compd. by the irradiation with light L2 having separate wavelength, such as phenyl acetate as essential component. The compsn. is used by coating together with a binder and a solvent on a base material. When, for example, the coated film is irradiated with the light having 200-350mmu wavelength L1 through a pattern, BHPM develops color to obtain a yellow-orange image, and the photosensitive compsn. is inactivated by the further irradiation with the light having the wavelength L2 to obtain an image having a stable background. When the compsn. is first irradiated through a pattern with the light of the wavelength L2, then further irradiated with the light of the wavelength L1, a latent image is allowed to develop color.

Title: Apparatus for positioning of calculus in body of living organism
Inventor: FURIIDORITSUHI UEBERURE
IPC: A61B6/00
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To simplify and improve the method for determining the position of calculus and exclude the need to interrupt the treatment of the patient even if the position of calculus is shifted during breaking, by constituting marks with a first portion which can be scanned by light beam and a second portion which can be scanned by X-ray beam. SOLUTION: The body 1 of a patient is first transmittedly irradiated by a perpendicular incident X-ray beam 2, and then by an inclined incident X-ray beam 3, thereby the position of the calculus for the following shock wave treatment is determined in the X, Y, Z coordinate. After the position is determined by the two X-ray beams 2, 3, appended position marks 8, 8' are attached to the surface of the body. These marks are formed by different materials of which e.g. the material 8 is sensitive to the incident light beam 4 illuminated by a light source 5, and the material 8' is sensitive to the incident X-ray beam. If the appended marks 8, 8' move away, a control device 6 will move the sleeping chair to enable the appended marks 8, 8' to return to the original position.

Title: Optical transmission device
Inventor: FUJITO KATSUYUKI
IPC: H04B10/2507
Filed: 1981-06-01
Abstract: PURPOSE:To prevent the titled device from the influence of reflected noise through simple configuration by fixing the length of a transmitting fiber between a laser diode and a capacitor on a half or less of the wavelength of a component having the maximum frequency of a transmission band. CONSTITUTION:If the length of a pig tail fiber 2 between a laser diode 1 and a capacitor 3 is regulated to a half or less of the wavelength of maximum frequency of a signal transmitted by the optical system, a peak component of reflected noises is located at the outside of a transmission band and does not exert the influence on the optical system. Thus, a transmission device prevented from the influence of reflected noises is produced through simple configuration.

Title: Video reproducing device
Inventor: ARIKAWA SHUNICHI
IPC: H04N5/57
Filed: 1989-04-05
Abstract: PURPOSE:To apply contour correction in response to a change in the brightness of a picture by providing a control voltage generating circuit using a detected voltage (brightness detection voltage) generated by an automatic brightness limit circuit to generate a control voltage and a gain control circuit controlling the gain for speed modulation operation through the control voltage. CONSTITUTION:When the brightness is low and a brightness detection voltage is higher than a Zener voltage of a constant voltage diode 14, an amplitude of a.video signal outputted from a collector of a transistor(TR) 12 is small. On the other hand, when the brightness is high and the brightness detection voltage is lower than the Zener voltage of the constant voltage diode 14, an amplitude of a video signal outputted from a collector of the TR 12 is high. Thus, the amplitude of the output video signal of a gain control circuit is constant when the brightness detection voltage is a prescribed value or over by supplying the output video signal of the gain control circuit 2 to the speed modulation circuit and the speed modulation gain is made constant. Since the amplitude of the output video signal of the gain control circuit is increased as the brightness detection voltage decreased with the brightness detection voltage being at a prescribed value or below, the gain of the speed modulation operation is increased.
