Title: Solid-state image pickup device
Inventor: IWADE SHIYUUHEI
IPC: H04N5/335
Filed: 1983-07-04
Abstract: PURPOSE:To remove optical crosstalk between light detecting elements perfectly by separating plural light detecting elements by separating insulating layers of adjoining elements and a semiconductor substrate having a conductive form opposite to a semiconductor layer that constitutes an active layer. CONSTITUTION:Light detecting elements are cooled in a p type semiconductor layer 11 to such a degree that a positive hole is not thermally excited, and a voltage is applied between the first conductive layer 4a and the second electrode 8 in such a degree that the potential of the latter becomes high and a depletion layer that spreads from the boundary face between a p type semiconductor layer 11 and an n type semiconductor substrate 10 arrives at the first p<+> type area 2a. When light is irradiated under this condition, the positive hole generated by light incident to the p type semiconductor layer 11 is collected to the first p<+> type area 2a by strong electric field in above-mentioned depletion layer. Similarly to former examples, it is shifted to the first electrode 6 through a channel formed by a negative voltage applied to the conductive layer 4b and wiring 5, and the potential of the first electrode 6 shows a value proportional to the intensity of incident light. An adjoining light detecting element B is separated by a separating insulating layer 13 and an n type semiconductor substrate 10.

Title: Analog optical transmission method and device thereof
Inventor: YAMAMOTO HIROAKI
IPC: H04B10/60
Filed: 1993-05-25
Abstract: PURPOSE:To reduce noise and distortion generated by the multiple reflection within a transmission line by converting a multiplexed electric signal into an optical signal by a semiconductor laser via a filter after the signal is converted higher by a prescribed frequency by a mixer and transmitting the signal by an optical filer. CONSTITUTION:The signal where the input signals 101 to 103 of an optical transmitter 3 are modulated by modulation circuits 11 to 13 by carrier frequencies f1 to f3 is outputted as a multiplexed signal A by a multiplexor 5. An input mixer 130 takes product of this signal A and the signal B of the frequency f0 from a local oscillator 150, and a filter 300 extracts a signal C where each f0 is added to f1 to f3 from the mixed signals. A semiconductor laser 10 transmits an optical signal where an optical intensity modulation is performed for the signal C to an optical fiber transmission line 200 and the light receiving circuit 20 of a light receiver 4 converts this optical signal into an electric signal. A mixer 140 takes the product of this electric signal and the frequency f0 from a local oscillator 160, a filter 310 extracts the components of frequencies f1 to f2 and a demodulation circuit 31 performs a demodulation. Thus, noise and distortion due to the multiple reflection within a transmission line is reduced.

Title: Crosstalk cancel system resulting from pattern wiring
Inventor: KATSUMATA NORIAKI
IPC: H01L23/522
Filed: 1990-05-14
Abstract: PURPOSE:To cancel crosstalk affected onto other pattern wiring due to a signal of the relevant pattern wiring effectively by providing a guard pattern arranged in parallel corresponding to each pattern wiring and driving the guard pattern with a current of opposite polarity to that of the signal of the pattern wiring and proportional to the level of the signal. CONSTITUTION:A signal of opposite polarity through an inverting amplifier 52 and a current output Ix with a level proportional to a transmission signal through current amplifiers 421, 422 are fed respectively to guard patterns 232, 233 in the case of signal transmission from a driver 12 to a receiver 32. Thus, an induced voltage from a pattern wire 22 and an induced voltage of opposite polarity from guard patterns 232, 233 driven by an inverting amplifier and a current amplifier are generated in the pattern wire 21. That is, the induced voltage of the transmission signal through the pattern wire into an adjacent pattern wire is cancelled by the drive current of the guard pattern. Thus, crosstalk is reduced while decreasing the circuit integration of the pattern wires and eliminating the need for a multilayer board.

Title: Dehydration device, and pressure feeder and dehydrator to be used the same
Inventor: UDAGAWA MASAYOSHI
IPC: B01D29/90
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To continuously suck and dehydrate a material to be dehydrated which is fed under pressure and injected into the filtration chamber of a dehydrator and happens to be thin, until the specified amount of cake is reached, without causing the particulate matter of the material to be dehydrated to mar the inner wall face of a plunger drum on a pressure feeder.

In addition, the face pressure of the sliding face plate 27 is increased stepwise to a high level by supplying an air into the filtration chamber 29 to move the sliding face plate 27 forward intermittently. Thus the material to be dehydrated 5 is compressed and then is sucked and dehydrated by vacuum pumps 30, 31.

Title: Drum device
Inventor: MATSUMOTO HIROYUKI
IPC: B65H49/24
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To make applicable a tensile force to an object being drawn out with a simple structure, and to make preventable an idle running of a drum. SOLUTION: This drum device comprises a drum 10 integrally formed with a coaxial hollow cylinder 14, a capillary 12 wound around the peripheral face of the drum 10, and glass beads 15 partially filled in the hollow cylinder 14. Drawing-out of the capillary 12 rotates the hollow cylinder 14 together with the drum 10 to move the glass beads 15 within the hollow cylinder 14 to the rotation direction. At that time, because the moved glass beads 15 tend to return to the original stable position by gravitation, a rotational force opposite to the rotating direction occurs in the hollow cylinder 14 and the drum 10 to apply a tensile force to the capillary 12. The displaced glass beads 15 also apply a force preventing an idle running of the drum 10 caused by the inertia of the drawing out of the capillary 12.

Filed: 1988-05-23
Abstract: PURPOSE:To facilitate selection and design of a constituent material for a recovery device and enable recovery of iodine in high yield by adsorbing free iodine prepared by combining reductive and oxidative reactions on active carbon. CONSTITUTION:An organic iodine compound, especially a roentgenographic contrast medium, industrial germicide, etc., is produced. An organic iodine compound generated in a waste liquor produced in the above-mentioned process is deiodinated by catalytic hydrogenolysis, reductive reaction with metallic zinc, tin, aluminum or iron, under acidic conditions or electrolytic reductive reaction, etc. An oxidizing agent, such as a solution of sodium hypochlorite, is then added to the resultant product and oxidized to liberate iodine. The obtained free iodine is subsequently adsorbed on active carbon. Thereby, the iodine can be recovered at about >=80% recovery ratio according to the afore- mentioned method.

Inventor: GOTO SEIJI
IPC: G01J3/04
Filed: 1985-06-06
Abstract: PURPOSE:To detect the origin easily with a high accuracy in a simple structure by detecting a spectral luminous flux, which is given through a variable slit, by a photodetector for spectral measurement. CONSTITUTION:A spectral luminous flux L is made incident through an entrance slit hole 5a and is reflected on a main mirror 2 and is made incident on a dispersing element 3. It is dispersed in accordance with the wavelength of the luminous flux and is reflected on the main mirror 2 again and is made incident on a photodetector 9 for spectral measurement through an exit slit hole 6a. The light emitted through the slit hole 5a and the slit hole 6a during this period is increased or reduced in accordance with the rotation position of a variable slit 4. When respective centers of the slit hole 5a and the slit hole 6a are in the center line, the detection output of the photodetector 9 is maximum. Slit holes having a relatively wider width in the vertical direction are used, and the rotation position where the detection output of the photodetector 9 is maximum is detected, thereby detecting the origin.
