Title: Optical image signal transmitter
Inventor: MATSUSHITA SHINICHI
IPC: H04B10/00
Filed: 1983-03-02
Abstract: PURPOSE:To compensate the nonlinearity of a light emitting element by providing two optical transmission lines and applying modulation to their electrooptic coversion parts by reversing the polarities, i.e. of positive and negative. CONSTITUTION:A transmission part 1 inputs an image electric signal A from an input terminal 3 and an electrooptic converting circuit 4 modulates the driving current of a light emitting diode, etc., by the electric signal to obtain a light signal, which is sent out to an optical transmission line 7. Namely, positive modulation is applied at this time in such a way that the direction of a horizontal synchronizing signal 15 makes the level of the light signal small. Further, the inputted image electric signal is inputted to a polarity inverting circuit 5 as well to be inverted in polarity and applied as an image electric signal B to an electrooptic converting circuit 6, which sends out a light signal after negative modulation to a transmission line 8. A reception part 2 converts the light signal sent from an optical transmission line 7 into an electric signal by an optoelectric converting circuit 9. The light signal sent from a transmission line 8, on the other hand, is converted into an electric signal by an optoelectric converting circuit 10 and this converted electric signal is inverted in polarity by a polarity inverting circuit 11. This polarity-inverted signal and said electric signal are applied to an adding circuit 12, which generates an output signal 13.

Title: Sealing method for molten metal and charging nozzle in horizontal continuous casting machine
Inventor: NAKAMURA TERUSHIGE
IPC: B22D11/06
Filed: 1981-03-13
Abstract: PURPOSE:To prevent the leakage and penetration of molten metal during casting in a gold pin type horizontal continuous casting machine by blowing a high pressure gas into the clearance between a mold and a contact piece from behind the contact piece. CONSTITUTION:A contact piece 8 is provided via a heat insulating material 9 between a mold 2 and a charging nozzle 3, and a flat pipe 10 is disposed in the material 9. A gas nozzle 18 which blows a high pressure gas toward the clearance between the mold 2 and the piece 8 is disposed behind the piee 8.

Title: Manufacture of oxidizing catalyst consisting of perfluorocarbon polymer and carbonyl compound
Inventor: NOZAKI HAJIME
IPC: C07C67/00
Filed: 1984-02-28
Abstract: PURPOSE:To form efficiently the titled carbonyl compd. by oxidizing an alcohol in the presence of a polymer consisting of a side chain having a Cr (III) difluromethylenesulfate or a Ce (IV)) group and a main chain of perflurocarbon. CONSTITUTION:The carbonyl compd. is efficiently formed by oxidizing an alcohol in the presence of a perflurocarbon polymer consisting of a side chain having a Cr (III) difluoromethylenesulfonate or a Ce (IV) group as a structural unit and a main chain of perflurorocarbon. The catalyst is used instead of an expensive Cr (VI) having wastes treatment problems and the oxidizing agent having no wastes treatment problems can be detected. The yield of the product is high, and the gummy precipitate is not formed. The catalyst is easily separated from the liquid product, since the catalyst is solid. The catalyst can be used under drastic reaction conditions due to its high resistance to oxidation, chemicals such as solvents, and heat, and can be advantageously regenerated.

Title: Image forming device
Inventor: YAMAMOTO YASUYOSHI
IPC: H04N1/29
Filed: 1988-02-18
Abstract: PURPOSE:To separate one developing system from a photosensitive body when the other developing system approaches said body and to prevent an image of mixed color by connecting two developing systems with a lever member and turning them by means of a cam mechanism so as to move together. CONSTITUTION:The release lever 105 is bridged between the developing systems 11a and 11b, and turns around a fixed axis 106. The lever 105 comes into contact with release pins 104a and 104b provided on the developing systems 11a and 11b. As cams 101a and 101b rotate around cam axes 102a and 102b at the same speed, the developing system 11a pressed by the cam 101a moves to left and becomes close to the photosensitive body 10. At that time, the release lever 105 turned counterclockwise by the release pin 104a pushes the release pin 104b to right, and the developing system 11b hence retreats from the photosensitive body 10. As mentioned above, the developing systems 11a and 11b come nearer or farther from the photosensitive body 10 repeatedly whenever the cams 101a and 101b rotate by 180 deg.. Thus, the developing systems 11a and 11b never approach the photosensitive body 10 simultaneously, thereby preventing the formation of an image in mixed color.

Title: Detecting device of reel runaway
Inventor: MITSUNE NORICHIKA
IPC: G11B15/43
Filed: 1982-03-08
Abstract: PURPOSE:To detect a runaway securely by counting speed detection pulses of motors for a supply and a take-up reels and resetting the opposite counters by speed detection pulses mutually, and detecting an abnormal counter value. CONSTITUTION:The supply reel 1 and take-up reel 2 are dreiven by the motors 16 and 17. Speed detection pulses of the motors 16 and 17 are generated by frequency generators (FGs) 16' and 17' and counted by counters which are not shown in a figure, and the opposite counters are reset mutually by the speed detection pulses generated by the FGs 16' and 17'. Further, a runaway of a reel is detected by detecting whether the counter value of one counter is less than a specific value or not. While a tape runs normally, the ratio of the counted values is nearly 3.2:1-1:3.2. Thus, an abnormal value is detected to make a shutoff, preventing the runaway of reels.

IPC: B25J17/02
Filed: 1989-02-17
Abstract: PURPOSE:To enable engaging insertion without the occurrence of pushing force between inserting and inserted substances even if the positioning accuracy between them is inferior by providing a fluid bearing mechanism between a substance retaining mechanism main body and a substance. CONSTITUTION:Fluid is suctioned from a ring groove 19 through a conduit line 21 and a fluid suction passage 20 with a fluid suction source 22, and the weight of a substance 1 is supported by the negative pressure within the groove 19.

Therefore, since the substance 1 is untouchably retained maintaining a given fine gap space to a holding surface 2A, the substance 1 can be freely moved to a direction along the surface 2A within a range limited with a blocking member 23, and the substance 1 at the time of insertion is guided with a taper part 4A, and alignment is automatically conducted even to an insertion position.

Title: Humidity detector
Inventor: ODA KOUICHI
IPC: G01H3/00
Filed: 1983-03-04
Abstract: PURPOSE:To detect humidity by utilizing that the antiresonance condition generated by a resonance vessel of a Helmholtz type and an interfering body of sound is sensitive with humidity. CONSTITUTION:A piezo-electric type oscillator 6 connected to an oscillating circuit is attached by node support to a Helmholtz type resonance vessel 2 having a sound releasing hole 4. An interfering body (acoustic wave reflector) 12 is provided in the prescribed position above the hole 4. The position of the body 12 where the antiresonance for stopping the oscillation arises exists just at one point for each of conditions when the humidity and oscillation frequency are determined. If, for example, the position of the body 12 is so set as to generate most sharply the antiresonance at 30% humidity, an oscillating sound pressure increases symmetrically from the point of 30% humidity in a humidity range of 0-60%. The change in the antiresonance condition owing to humidity is preferably detected from the change in the volume of the generated sound or the change in the impedance of the oscillator.
