Title: Production of silver halide photographic printing paper
Inventor: UESAWA YUTAKA
IPC: G03C1/42
Filed: 1987-06-04
Abstract: PURPOSE:To form photographic printing paper having high whiteness even under rapid processing conditions by mixing an emulsion with polymer latex and incorporating the mixture into a photographic element. CONSTITUTION:When an emulsion contg. an oil soluble fluorescent whitening agent dissolved in a high b.p. org. solvent and polymer latex are incorporated into a photographic element contg. a silver halide developer on a support, the emulsion is mixed with the polymer latex and the mixture is incorporated into the element. The emulsion is prepd. by dissolving the whitening agent in the high b.p. org. solvent mixed optionally with a low b.p. org. solvent, mixing the resulting soln. with an aq. gelatin soln. contg. a surfactant and emulsifying the mixture with an emulsifier such as a colloid mill, a homogenizer or an ultrasonic dispersing device. Thus, rapidly processable silver halide photographic printing paper having high whiteness can be formed.

Filed: 1993-05-21
Abstract: PURPOSE:To provide a new nonlinear optical material comprising a complex extremely easily obtained only by mixing a benzoic acid derivative with a pyridine derivative, exhibiting excellent nonlinear optical characteristics, and capable of being suitably utilized in the field of optoelectronics. CONSTITUTION:A benzoic acid derivative of formula I (R<1> is electron-acceptable group, electron-donating group) is mixed with a pyridine derivative of formula II (R<2> is electron-acceptable group, electron-donating group, but R<2> is a group different from R<1>, and when R<1> is the electron-acceptable group, R<2> is the electron-donating group, or when R<1> is the electron-donating group, R<2> is the electron-acceptable group) preferably in a solvent to produce a molecular complex. The complex expresses far higher nonlinear optical characteristics than the case where the compounds are singly used, respectively, and exhibits approximately the same nonlinear optical characteristics as those of urea. Since the ends of absorbed wave lengths are short, the complex has a sufficient characteristics as a practical nonlinear optical material.

Title: Magnetooptic recording and reproducing device
Inventor: OOTA KENJI
IPC: G11B11/10
Filed: 1980-10-09
Abstract: PURPOSE:To prevent the incidence of return light to a laser beam sorce by arranging a Faraday effect element, having a plane of polarizatin rotatable by 45 degrees, between a couple of polarizing prisms whose transmission axes are set at 45 degrees. CONSTITUTION:On the optical path of laser beam polarizing prisms 5 and 7 whose transmission axes are set at 45 degrees are provided and between the two, Faraday glass 6 whose plane of polarization is rotatable by 45 degrees is arranged. In this constitution, the laser beam is passed through the prism 5 to obtain linear polarized light, which is turned by 45 degrees by the Faraday glass 6 to strike a recording track 23 by way of the prism 7, so that its reflected light is guided to a photodetector 15 through a beam splitter 8. In this case, the elliptic polarization component of the reflected light are removed by the prism 7 and its azimuth angle is increased by the Faraday glass 6 by 45 degrees to have a 90 degrees azimuth angle to the transmission axis by the prism 5. Therefore, it never returns to a laser beam source 3 and is reflected in a direction C, thus preventing the incidence to the light source.

Title: Agricultural film having excellent anti-fogging durability
Inventor: OGAWA TAKESHI
IPC: C08L23/00
Filed: 1981-09-09
Abstract: PURPOSE:To provide an agricultural film having improved anti-fogging durability, by coloring an agricultural film contg. a drip-proofing agent black, and adjusting its light transmittance to a specified value. CONSTITUTION:In an agricultural film contg. a drip-proofing agent, the film is colored black and its light transmittance is adjusted to 30% or above. The reason why anti-fogging durability is improved by coloring the agricultural film contg. a drip-proofing agent black, is thought to be that by coloring the film black the temperature of the film itself is raised by sunlight in the daytime, water is hardly condensed on the surface of the film, the durability of the drip- proofing agent is improved and hence anti-fogging effect is maintained. When light transmittance is less than 30%, the amount of light to be transmitted is insufficient and the film can not be used effectively. The film having a light transmittance of 70% or above can be used as ordinary agricultural covering material. The film having a light transmittance of 30-70% can be used as a sunproofing agricultural covering material for soft vegetables, paddy nursery and shiitake (mushroom) culture.

Title: Manufacture of surface acoustic wave device
Inventor: KONDO TAKEO
IPC: H03H3/10
Filed: 1991-06-13
Abstract: PURPOSE:To reduce the dispersion of a resonance frequency and to improve yield by forming plural electrode patterns differing in the electrode duty corresponding to the thickness of a conductive film of a wafer. CONSTITUTION:Metal such as aluminum or the like is deposited on the surface of a conductive material wafer 2 by vacuum deposition. When a conductive film 6 is formed by the vacuum deposition, the conductive film 6 shows the thickness distribution of a thick center and a thin outer periphery. Next, the surface of the conductive film 6 is uniformity coated with a resist film 5 and exposed by using the mask of the prescribed electrode pattern. In that case, the exposure amount is increased at the center corresponding to the thickness distribution of the conductive film 6 and gradually reduced toward the peripheral part. Therefore, the electrode patterns formed by etching have the various duties for each part of the wafer corresponding to the thickness distribution of the conductive film 6. Namely, since the electrode pattern is formed so that the electrode duty is larger at the central part and smaller at the peripheral part, the dispersion of the resonance frequency is reduced.

Abstract: PURPOSE:To prevent malfunctions of a robot by using a sequencer independent of a controller that controls robot actions to control the robot sequence. CONSTITUTION:All sequences X of robots 10 and 12 are stored to a sequencer 28. When the 1st robot 10 reaches a prescribed area, the sequences X are stored to a controller 20 as the sequence Y. Thus the robot 10 performs actions based on the sequence Y. When these actions are through, the sequence (X-1) excluding said actions is stored to the sequencer 28. When the 2nd robot 12 reaches a prescribed area, the sequence (Y-1) is stored to a controller 22. Then the robot 12 performs actions according to the sequence (Y-1). Then the sequence (X-2) is stored to the sequencer 28.

Abstract: PURPOSE:To automatically set up a white/black deciding threshold by providing the title image reader with a threshold setting part for subtracting a margin from the value of a video signal corresponding to a drop-out color printed on an original and setting up a white/black deciding threshold. CONSTITUTION:A processor 6 recognizes the reading value of a painted-out part M of a drop-out color from a digital video signal for a line (b) of an original F stored in a memory 7, subtracts the value of a margin from the read value as a white/black deciding threshold and stores the calculated threshold in a register 5. An output signal from an A/D converter 2 is compared with the white/black deciding threshold set up by the register 5 through a comparator 3 every reading out one line by a line sensor 1 and a drop-out color larger than the threshold is decided as white. Thus, the white/black threshold can be automatically found out and reading operation can be executed in accordance with the threshold corresponding to an original to be read out.
