Title: Recovery of cerium
Inventor: FURUICHI HIROSHI
IPC: C01F17/00
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for profitably recovering cerium by removing dissolved chromium from a waste chromium etchant containing ammonium cerium (IV) nitrate used for etching chromium. SOLUTION: This method for recovering cerium from a waste chromium etchant used as an etchant for etching thin chromium films, i.e., a cerium and chromium-containing solution, comprises supplying the waste etchant with an extractant comprising an organic solvent and hydrogen peroxide to reduce the contained tetravalent cerium to trivalent cerium and transfer chromium to the solvent phase, separating the chromium-containing solvent phase from the water phase to separate and remove the chromium, and recovering the cerium in the water phase. The etchant uses the cerium recovered by the above method for recovering the cerium.

IPC: G03F7/00
Filed: 1983-09-16
Abstract: PURPOSE:To enhance reproducibility of image lines and printing resistance by giving a photosensitive layer a spectral sensitivity distribution having the max. spectral sensitivity in a specified region and a small spectral sensitivity up to 1/10 of said max sensitivity in a specified wavelength region. CONSTITUTION:A photosensitive layer formed on a flexible support has a spectral sensitivity distribution having the max. sensitivity in the wavelength region longer than 700mum, and a spectral sensitivity up to 1/10 of said max. sensitivity in the wavelength region of 450-480mum. The flexible support is, preferably, selected from a sheet material having especially superior dimensional stability and a hydrophilic surface. The compsn. of the photosensitive layer having such a spectral sensitivity distribution is exemplified by a photosensitive resin compsn. composed of, e.g., a compd, having groups represented by the formula on the main chain or side chains of a polymer, and a sensitizer capable of initiating cross-linking and hardening of this compd. on absorbing the light of wavelengths longer then 700mum. A photosensitive lithographic plate having such a structure exhibits excellent reproducibility of an image when it is imagewise exposed to semiconductor laser beams.

Filed: 1983-09-17
Abstract: PURPOSE:To prevent the erroneous operation due to noise voltage by inputting a power-source voltage and a signal voltage or its processing voltage into a circuit which prossesses memorizing function and preventing an ignition coil from being energized until the circuit is reset after it is set one time. CONSTITUTION:A flip-flop circuit (FF)8 installed onto the ignition apparatus of an internal-combustion engine inputs a power-source voltage and a signal voltage or its processing voltage into a wave-form processing circuit 5, and used as memory circuit for preventing an ignition coil 3 from being energized at least until the circuit is reset after it is set one time. The power-source voltage is applied into the input terminal S of FF8, delayed by a slight time by a delaying circuit 10. The output voltage of a transistor 5b is applied onto a reset input terminal R, and the output signal supplied from an output terminal Q is input into the base of the transistor 5e through a diode 9. Therefore, the circuit is temporarily locked on starting by the output signal of FF8 on starting, in order to prevent the ignition coil 3 from being energized.

Filed: 1980-12-05
Abstract: PURPOSE:To prevent the adhesion of a brazing material and flux onto the surface of a semiconductor element by arranging a block made of a material having large thermal capacity onto a radiator near the element. CONSTITUTION:The thickness of the block 27 in Cu, etc. is thicker than that of the semiconductor element 21, and its inner circumference is coated previously with resin 33 such as Teflon. The brazing material 31 such as solder is placed on a radiator plate 22, and the element 21 and the block 27 in a shape that surrounds the element 21 are positioned. When a jig 32 is contacted with the block 27 and the block is scrubbed, the brazing material 31 is melted, and the element 21 and the blcok 27 are fastened onto the radiator plate 22. The surface of the element is not moistened with the brazing material because there is a resin film on an inner circumference of the block 27, the brazing material does not crawl up to a contact section even when the element 21 contacts with the inner circumference of the block, and the lowering of yield and the complication of a process can be prevented while also increasing the thermal capacity of the radiator plate.

Title: Communication control system
Inventor: HOSHI KAZUNORI
IPC: H04L12/70
Filed: 1989-07-05
Abstract: PURPOSE:To improve the throughput of a communication network by opening a communication path for an outgoing signal and a returning signal when no signal exists in a channel after the return of the returning signal and applying packet communication including plural message packets when the absence of the signal in the channel is consecutive for a packet interval or above. CONSTITUTION:A communication end detection section 70a is constituted of 4 NOR gates 72, a shift register 74, an AND gate 76 and one OR gate 78, the NOR gate 72 takes OR between a signal from an input port and a signal from an output port 30 and the shift register 74 detects the end of communication based on the time by a communication end detection time constant. The 4-input OR gate 78 informs to a sequence control section 90 that there is a finished communication among communication whose communication path is fixed or 1st outgoing signal from a first coming input channel is interrupted. Thus, an end control section 70 identifies that both of two input channels included in the communication with fixed communication path have no signal as the end of communication.
