Title: Document picture processor
Inventor: KUWATA NAOKI
IPC: G06T7/40
Filed: 1990-08-27
Abstract: PURPOSE:To reduce the processing manpower required by the title processor by recognizing characters and graphics which have been handled as image information and converting the characters and graphics into suitable code data. CONSTITUTION:An area dividing section 105 divides inputted image information into a character area, graphic area, and image area by finding the black picture element density of the areas of an inputted picture other than the blank area extracted by means of a blank area extracting section 104. A character area processing section 106 performs extraction of character strings, segmentation of one character, and recognition of a segmented character in the divided character area and a graphic area processing section 107 performs recognition after extracting geometrical figures and characters. Then an image area processing section 108 leaves the image area as image information or performs a compressing or contracting process on the image information and a reconstituting section 109 reconstitutes the area converted into the code data and the area of the image data on paper. In addition, a picture outputting section 110 outputs the reconstituted document information. Therefore, a document can be preserved without manual aid.

Title: Method for joining ceramics to ceramics
Inventor: SHINYA NOBUAKI
IPC: C04B37/00
Filed: 1991-08-09
Abstract: PURPOSE:To mutually join ceramics in high strength with high efficiency without carrying out pretreatment. CONSTITUTION:Nickel-chrome plates 3 and a stress material (nickel plate) 4 are placed between mutual ceramics 1, which are heated, pressurized in a prescribed vacuum state and joined to each other. Only the chrome in the nickel- chrome plate penetrates into the ceramic surfaces to form a chromium-metallized layer. The nickel is simultaneously diffused to the side of the ceramics to prevent nickel-silicon compounds from forming. Thereby, the joining strength and heat resistance in the joined parts are improved.

Title: Semiconductor device
Inventor: YAMANAKA TADAO
IPC: H03K5/14
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device in which the delay time of an output signal from a PLL with respect to an external clock signal is charged after the device is mounted on a system. SOLUTION: An external clock signal is given to an input terminal 1. An address value is given to an input terminal 3. A decoder 9 selects any of a plurality of delay times in a voltage controlled oscillator 8 depending on the address. The phase of a signal outputted to an output terminal 2 is delayed by the selected delay time selected from that of the external clock signal at the input terminal 1. Thus, after mounting the device to the system, the delay time of the output signal from the PLL with respect to the external clock signal is changed.

Title: Production of (meth)acrylic ester
Inventor: KIMURA KOJI
IPC: C07C69/54
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a (meth)acrylic ester in an improved yield without the need of using any aqueous alkaline solution in the neutralization process to effect reducing the quantity of waste water produced in the production process. SOLUTION: This method for producing a (meth)acrylic ester comprises adding a solid acid-neutralizing agent such as magnesium oxide, synthetic hydrotalcite or magnesium hexasilicate to a reaction liquid containing the objective (meth)acrylic ester produced, for example, by esterification between (meth) acrylic acid and the corresponding alcohol to eliminate the acid in the reaction liquid. As a result, because of no need of using any aqueous alkaline solution, yield drop of the (meth)acrylic ester due to its removal through migration into an aqueous layer can be prevented, and furthermore waste treatment process can be simplified owing to reduction in the quantity of waste water, thus mitigating load on the environment.

Filed: 1987-09-11
Abstract: PURPOSE:To provide the title device that can reduce errors of a measured value of the distance as a result of the change of temperatures, by providing a phase shifting circuit for shifting 90 degrees the phase of a reference signal or an output signal of a light receiving element, a first and a second phase difference detecting circuits, a differential circuit, etc. CONSTITUTION:Driven by an oscillating output of an oscillating circuit 3, a laser beam which is modulated in strength is projected to an object from an LD (laser diode) 1. The reflected light is received by a PD (photodiode) 2. An output of a phase- shifting circuit 5 which shifts the phase by 90 degrees and a reference signal are inputted to a phase difference detecting circuit 6. Although an output voltage of the circuit 6 is ideal by zero, actually it is higher or lower than zero by a drift voltage  phi. On the other hand, an output voltage of a phase difference detecting circuit 4 which represents distance informations is similarly increased by an offset voltage  phibecause of the temperatures, to be phi+ phi. The output voltage of each of the circuits 4 and 6 is supplied to a differential circuit 7, whereby the offset voltage  phiis cancelled. Accordingly, a signal representing the phase difference phi between the reference signal and the output signal of the PD2 is obtained based on which the distance to the object is calculated.
