Title: Photo-sensitive lithographic printing plate
Inventor: ENDO TADASHI
IPC: C23C22/05
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To improve the erasability of the photo-sensitive layer in a correction process after an image-developing process, and also, make a non-image part hard to stain in printing by a method wherein an aluminum supporting body which is treated with a solution containing a periodic table group VIII transition element metallic salt of an aliphatic monocarboxylic acid at a specified tempera ture, after an anode oxide film is formed, is used. SOLUTION: By an anode oxidation process, an anode oxide film is formed on an aluminum plate or an aluminum alloy plate. Then, this plate or the alloy plate is treated with a solution containing a periodic table group VIII transition element metallic salt of an aliphatic monocarboxylic acid at 30-60 deg.C, and is used as an aluminum supporting body. By performing this treatment, a photo-sensitive lithographic printing plate wherein the surface area per unit geometrical area of a non-image part after an image-developing process, is 5-50 m<2> /m<2> , and a contact angle of a water drop in oil becomes 50 deg. or less, can be obtained. By using such a photo-sensitive lithographic printing plate, the erasability of the photo-sensitive layer is improved, and also, the non-image part becomes hard to contaminate at the time of printing.

Data correction is processed, the increment processing of the number of groups is executed, a syndrome correction processing is executed and a loop processing for judging the termination of all sequences is executed for all the sequences. Thus, a correction processing is executed. In the correction method, a parity is once generated instead of the technology of the generation of the party by reading data from buffer RAM at every time. Whenever an error is corrected, the parity is corrected by the error pattern. Thus, the number of times of accessing the buffer RAM can be reduced.

Title: Information recording/reproducing device
Inventor: SANAI KOJI
IPC: G10L15/00
Filed: 1990-10-22
Abstract: PURPOSE:To optionally reproduce only the necessary voice information by inputting the voice signal, recognizing the voice with a retrieval word text and a header word text, determining the cutting point of the voice sentence from the result, and cutting and outputting the stored voice sentence. CONSTITUTION:The voice signal from either a telephone 11 or a radio 12 is inputted to filters 3, 13 via a switch Sw. The voice from the filter 3 is stored in an information memory section 28 via a record/regeneration section 4. The voice signal from the filter 13 is converted into the voice recognition data by a voice recognition section 14 and stored in a memory section 19. The recognition section 14 data-collates the voice recognition data stored in the memory section 19 with a retrieval work text stored in a memory 15 and recognizes whether they are the same word or not. If they are recognized as the same word, a controller 17 detects the start point of the voice sentence and cuts out the recognition data for a fixed period from the memory section 19 and transfers them to a memory section 16, it detects the end point from a silent section, and it cuts out the information memory data from the memory section 28 and transfers them to a memory section 20. When a switch 21 is pushed, the data of the memory section 20 are outputted from a speaker 7.

Abstract: PURPOSE:To increase the degree of accuracy and, in addition, to enable analysis of the quantity of C and the quantity of S in a wide component range without changing conditions of measurement, by providing a weight correcting means for measured values and a means of correcting a working curve in accordance with the measured values subjected to the weight correction. CONSTITUTION:A sample weighed by a balance is put in a crucible made of ceramics and burnt in an oxygen flow. At this time, carbon and sulfur in the sample are turned into CO2, CO and SO2 and they are carried by the oxygen flow and led to a non- dispersive infrared detector (measuring element). Herein the concentration of gas is measured and the quantities of C and S are calculated from the concentration of gas. Next, the entire concentration areas of C and S are divided by a weight correcting means, and with a difference between the average measured values of C and S in a sample of a standard weight in each discrete concentration area and the average measured values of C and S of a sample of an arbitrary weight smaller than the standard weight, used as a deviation number, the weight correction of the measured values is executed. By a working curve correcting means, subsequently, correction of a working curve is executed in accordance with the measured values subjected to the weight correction, on the basis of a plurality of working curve coefficients corresponding to the concentration areas of C and S.

Inventor: TANAKA YOICHIRO
IPC: H03K5/133
Filed: 1991-10-31
Abstract: PURPOSE:To change a delay quantity of a delay circuit into a delay quantity on request of the delay circuit by changing an electric signal level without external adjustment or the circuit change when the delay quantity of the delay circuit is changed. CONSTITUTION:Plural paths 2 used to interconnect delay circuits are formed in parallel between an input selection section 6 and an output selection section 7, and a path is selected by an electric signal inputted to an input terminal 5 of a control section 8. Then the delay from an input terminal 3 to an output terminal 4 depends on number of the delay circuits 1 included in the selected path. Thus, when the delay of the delay circuit after the circuit design is revised, the delay on request is realized by changing the electric level of the input signal of the control section of this delay circuit without addition of an external element or re-design.

Filed: 1985-12-18
Abstract: PURPOSE:To quickly and surely fix initially and finally wound ends of a wire to thereby improve a processing efficiency by applying a photo-setting adhesive to the initially and finally wound ends of the wire and then irradiating light to harden the photo-setting adhesive. CONSTITUTION:A photo-setting resin (a) is applied in advance to portions 1a and 1b whereto a wire 4 is to be fixed and the initially wound end 4a and the finally wound end 4b of the wire 4 which is positioned and wired along the portions 1a and 1b. When the application of the photo-setting resin (a) is terminated, the distal end of an optical fiber bundle 28 is brought close to the portions 1a and 1b to be positioned. A light for hardening the resin is generated from a light source device as a pulse light and transmitted through the optical fiber bundle 28 to be irradiated from the end of the bundle 28 onto the portions 1a and 1b. Since the resin photo-setting light is collected by a condenser lens 29 and irradiated as a spot light at this time, the photo-setting resins (a) and (a) applied to the portions 1a and 1b are instantaneously hardened. Therefore, the initially wound end 4a and the finally wound end 4b of the wire 4 are fixedly adhered to the portions 1a and 1a.
