Abstract: PROBLEM TO BE SOLVED: To produce the subject compound on an industrial scale at a low cost by hydroformylating an olefinic unsaturated compound in the presence of carbon monoxide, hydrogen and a metal complex catalyst and purifying the product by distillation. SOLUTION: An olefinic unsaturated compound (e.g. 1,3-butadiene and 1,5- hexadiene) is subjected to hydroformylation reaction in the presence of carbon monoxide, hydrogen and a metal complex catalyst. The obtained crude reaction liquid containing a dialdehyde (preferably 1,9-nonanedial, 2-methyl-1,8-octanedial, etc.), is mixed with 0.01-1 times mol of a t-amine (e.g. trimethylamine) based on the total acid content of the crude reaction liquid and 100-5,000 ppm (based on the total amount of the dialdehyde in the crude reaction liquid) of a compound such as phenols, benzophenones and benzotriazoles and the obtained mixture is subjected to steam distillation to separate the objective dialdehyde.

IPC: G06F13/00
Filed: 1985-10-17
Abstract: PURPOSE:To replace the defective area of an input/output controller without interrupting the execution of a program when said defect is detected, by using a means into a CPU to cut off the power supply of the input/output controller. CONSTITUTION:A CPU10, a memory device 20 and plural input/output controllers 30 and 40 are connected with each other via a common bus 100 and also connected with a power supply device 1 respectively. For instance, the defect of an input/output control part 32 of the controller 30 is detected by the CPU10. Thus the CPU10 gives a command to the device 1 to cut off the power supply voltage against the part 32 and also gives a command to an interface part 31 for logical cut-off. Thus it is possible to replace or repair the defective part 32 without cutting off the power supplies of other parts nor interrupting the execution of a program.

Title: Toner for electrophotography
Inventor: KO KATSUJI
IPC: G03G9/08
Filed: 1986-09-30
Abstract: PURPOSE:To obtain a high-quality image which is less fogged by using a spherical resin as a core material of a toner having two-layered structure and using a mixture composed of an electric charge controlling agent and resin having the m.p. higher than the m.p. of the core material as a film material. CONSTITUTION:The toner having the two-layered structure is formed by forming the film consisting of the mixture composed of the charge controlling agent and the resin having the m.p. higher than the m.p. of the spherical resin having a low m.p. on said spherical resin. Inasmuch as the low m.p. resin is used for the core material and the high m.p. resin for the film material, the high m.p. resin coats the circumference of the toner prior to fixing and, therefore, filming on the carrier and drum filming are decreased. The shells are ruptured and the core material resin of the low m.p. appears at the time of fixing. The fixability is thereby improved. The electric charge characteristic on the toner surface is stabilized and the splashing of the toner and fogging by the deterioration of the electric charge are obviated by coating the charge controlling agent on the core material resin.

Filed: 1989-09-11
Abstract: PURPOSE:To narrow the band of a laser light at the time of laser oscillation and to efficiently oscillate by providing a distributed feedback structure in a gas laser tube for a short pulse oscillation. CONSTITUTION:A distributed feedback structure 9 is formed of an optical material having a pectinated toothed uneven shape on the passage of a layer light 1. The refractive index n1 of the structure 9 is selected to a value higher than the refractive index n0 of laser gas 7. When the wavelength of a periodic structure of the uneven part is lambda, lambda2   2 lambda1 is satisfied with respect to a laser oscillation wavelength lambda2. Here, the symbol ( ) of near equality is employed because it is influenced by the nonlinearity of a laser medium. The feedback structure is introduced into the oscillation unit of a laser tube 2. Thus, only the light 1 of the wavelength indicated by the formula is oscillated, injection of energy to a discharge 6 is conducted with this wavelength to oscillate in the narrow band with high oscillation efficiency.
