Title: Production of 1,4-butanediol
Inventor: NISHIKAWA EIICHIROU
IPC: C07C27/00
Filed: 1988-07-15
Abstract: PURPOSE:To inexpensively and efficiently obtain 1,4-butanediol by one-stage reaction in high yield, by catalytically hydrogenating maleic acid anhydride and/or succinic acid anhydride by using a copper oxide-zinc oxide catalyst in a gaseous phase. CONSTITUTION:Maleic acid anhydride and/or succinic acid anhydride is hydrogenated in the presence of copper oxide-zinc oxide (especially preferably supported catalyst prepared by supporting cupric oxide on zinc oxide) as a catalyst in a high ratio of hydrogen/raw material under pressure to maintain a gaseous phase to give 1,4-butanediol. Since 1,4-butanediol is not passed through diesterifying process in this method, production process is extremely simplified. 1,4-Butanediol is obtained under extremely lower pressure than a method by hydrogenation in liquid phase to reduce cost of installation and operating cost.

Filed: 1988-07-15
Abstract: PURPOSE:To detect the completion of music under a reproduction by recording sub-code information to indicate a space between programs before rewriting the PNO of respective programs at the time of a re-number operation. CONSTITUTION:Another program is over-written (consecutive recording) in a magnetic tape to execute the re-number from the middle of the tape and a program number (PNO) = '01' and '02' being recorded in the sub-code area of respective programs is recorded in an overlapped condition. At the time of the re-number operation, the tape is rewound for a prescribed time (To) when the start ID(ST-ID) of the respective programs is detected, before the re-writing of the PNO, an Index = '00' to indicate the music space between programs from a position to be rewound to the recording start position of the PNO is recorded and this sub-code information is detected at the time of the reproduction. Thus, the completion of the program under reproduction can be decided without waiting for the ST-ID being recorded at the music head of a next program.

IPC: G01N35/02
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide an automatic analyzer effectively using plural reaction vessels to reduce a maintenance cost by changing first analysis assignment positions. SOLUTION: In Step 1, N=1 is assigned to positions of reaction vessels to be assigned for analysis first. A threshold M for the number of use of the reaction vessels is set as memory information, and it is decided in Step 2 whether a used number of the reaction vessels in the 1st positions in below M, and the 1st positions are stored and first analysis assignment is executed to the reaction vessels in Step 3 in the case that the used number of the reaction vessels in the 1st positions is below M. In the case that the used number of the reaction vessels in position N is larger than M in Step 2, positions satisfying the condition is retrieved in Step 4 and Step 5 by sequentially changing the positions of the reaction vessels such that the used number of the reaction vessels is below M.  In the case that the positions of the reaction vessels exceeds the number of all the reaction vessels in Step 5, the Nth position of the reaction vessels is reset to the 1st position that is the initial value and M is reset in Step 6.

IPC: G03B27/54
Filed: 1982-10-05
Abstract: PURPOSE:To reduce the blur of an aperture image to improve the capability of a face to be illuminated, by separating concaved and convexed light shielding plates, which constitute an arc-shaped slit aperture, from each other in the direction of the optical axis in an illuminating system using spherical mirrors. CONSTITUTION:A concaved light shielding plate 18A and a convexed light shielding plate 18B of a light shielding plate 18 constituting the arc-shaped slit aperture of the illuminating system where concave mirrors 11-13 are used to print a semiconductor are separated from each other in the direction of the optical axis and are so set that focus points S1 and S2 of respective end parts P1 and P2 are formed on the same plane K. The light of a spot light source 5 is reflected by the mirror 11 and is converged on the arc-shaped aperture. The light passing through the aperture part is reflected by mirrors 12 and 13 and is converged on the plane K. Since focus points S1 and S2 are formed on the same plane K, the blur of recessed and projecting edges is reduced very much, and the capacity of the face to be illuminated of semiconductor printing or the like is improved.

Title: Granular detergent arranged in unit weight
Inventor: OSHIRO MIZUHO
IPC: C11D17/04
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: Conventionally, synthetic detergents are packed in packings in the form of powders. When used, they are taken out by spoons or the like, so that metering of their amounts scatters significantly, raising inconvenience in consumption and explanation. In consequence, the detergents are divided in unit weights as granules so as to be merchandised and facilitated. SOLUTION: A detergent is divided in each unit weight as granules by packing it as tablets or in capsules. According to the invention, consumers can use detergents easily, and dealers can explain the use of detergents simply. Further, when a consumer himself indicates the amount of a detergent to others, expression of the amount is simple, so that the cause of misunderstanding is reduced.

Abstract: PURPOSE:To prevent the flow of an electrolyte even if a moisture content increases and to speed up the response action of the electrochromic (EC) element so as to solve the problem in hermetic sealing by using the electrolyte for the EC element consisting of a water absorptive polymer having a sulfonic acid group as its essential constituting component. CONSTITUTION:The electrolyte for the EC element consisting of the water absorptive polymer having the sulfonic acid group as its essential constituting component is interposed between a conductive substrate having the EC layer and a counter electrode substrate, by which the flow of the electrolyte is obviated even if the moisture content is increased and, therefore, the generation of liquid leakage is obviated. The water absorptive polymer or the like which is formed by polymerizing the vinyl polymer having the sulfonic acid group, a non-copolymerizable crosslinking agent and if necessary, other anionic vinyl monomer and/or nonionic vinyl polymer and may be neutralized or partially neutralized by an alkaline compd. is used as the water absorptive polymer having the sulfonic acid group.

Abstract: PURPOSE:To prevent reduction of the heat insulating efficiency accompanied especially by the humidification by forming a heat insulation pipe by a pipe body, a heat-insulating sponge layer of a silicon foamed body to coat the outer circumferential surface of this heat-insulating sponge layer. CONSTITUTION:A fire-proof heat-insulating pipe is formed by a pipe body 1, a heat-insulating sponge layer 2a of a silicon foamed body, and a sheath layer 2b of a silicon non-foamed body. That is, the inner layer consists of the silicon foamed body, and the outer layer consists of the silicon non-foamed body. The inner layer is foamed by irradiating the micro-wave of 900-5000MHz, and hardened. The outer layer is not foamed or hardened by irradiating the micro-wave, and is hardened only by heating. Thus, the outermost layer, i.e., the sheath layer 2b hardly indicates the humidification even under the high temperature and the high humidity environment, and the heat-insulating capacity of the heat-insulating sponge layer 2a to be positioned on the inner side is secured for a long time with a high level.

Title: Memory protecting circuit
Inventor: NOGUCHI MASAMI
IPC: G06F12/16
Filed: 1990-07-04
Abstract: PURPOSE:To identify the produced error information at an error processing stage in terms of a program by storing the illicit data in a memory address which is previously set to an illicit data storing address register. CONSTITUTION:An illicit data storing address register 12 sets previously a memory address to store the illicit data at occurrence of an ECC (error correction circuit) error. An illicit data latch circuit 13 latches the produced illicit data and latches temporarily the data. Then an illicit data storing write signal generating circuit 14 produces a write signal to write the illicit data into a set memory address. When an ECC error signal is significant, the circuit 14 produces an illicit data storing write signal 19. Then the illicit data latched by the circuit 13 is stored in the address of a memory 2 set to the register 12. Thus the ECC error occurrence state is identified at an error processing stage in terms of a program.
