Title: Attribute decision device
Inventor: ITEZONO TOSHIYUKI
IPC: G06K9/20
Filed: 1990-02-17
Abstract: PURPOSE:To specify attributes even when the attributes can be not be specified by conventional technique by deciding the attributes by using element features such as a character pitch, a character-to-character distance, and the number of characters. CONSTITUTION:A detection part 12 extracts character position information from document image data, character by character, and a decision part 14 finds element features regarding document constitution elements of one unit according to the character position information and decides the attributes of the document constitution elements according to the element features. When characters which have different attributes are presented in the same item field, the mean character pitch and means character-to-character distance obtained regarding the document constitution elements of one unit tend to be longer as to a name. An enterprise name, on the other hand, tends to be longer in the number of characters obtained regarding the character constitution elements of one unit. Consequently, those tendencies are utilized to decide the attributes.

Title: Fail-safe processor system
Inventor: SAITO KUNIO
IPC: G06F11/16
Filed: 1985-02-26
Abstract: PURPOSE:To make a fail-safe processor system practicable by converting always processor bus signals into analogs and also by comparing converted analog values with reference values through a fail-safe analog comparator. CONSTITUTION:At normal time, double series microcomputers 10 and 20 operate almost synchronously and the outputs coming from digital-analog converters 30A and 30B are nearly the same level having little deviation. Thus a failure detection relay FSAC detects that the comparator 31 normally oscillates. If data discrepancies occur, the outputs values coming from digital-analog converters 30A and 30B are so different that the comparator 31 stops oscillating. Accordingly, the failure detection relay FDA, being lacking in an exciting function, can detect any fail-safe failure of the double series microcomputers.

Title: Direct digital synthesizer oscillator
Inventor: KAWAGUCHI TSUNEJI
IPC: H03H19/00
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a synthesizer oscillator for obtaining an output with less spurious radiation by driving a waveform shaping part and a filter part with clock signals with different frequencies. SOLUTION: A clock generating section 15 receives frequency data fD and generates a 1st clock CK1 with an optimum frequency to be given to a waveform generating section 10 so as to allow the generating section 10 to generate an oscillation signal instructed by the received frequency data fD and from which spurious radiation components are easily eliminated by using a reference clock CLK. The clock generating section 15 generates a 2nd clock CK2 for a switching purpose that is used to select a filter characteristic such as a cut-off frequency of a switched capacitor filter 14 and to realize the filter characteristic by which the switched capacitor filter 14 filters oscillated by the waveform generating section 10 in an optimum wave to obtain a desired oscillation signal by using the reference clock CLK.

Title: Thermal transfer material
Inventor: KOTANI NOBORU
IPC: B41J31/00
Filed: 1986-02-21
Abstract: PURPOSE:To provide a thermal transfer material giving high resolution and capable of copying with high-speed printing, by using a fatty acid ester and paraffin wax as a binder, in a specified weight ration of 1:1-1:5. CONSTITUTION:A fatty acid ester and paraffin wax are used in a weight ratio of 1:1-1:5. If the amount of the ester is less than the weight ratio range, the capability of dispersing a coloring agent is lowered, so that reflection density is lowered, resulting in obscure prints. In addition, penetration is raised, so that ground contamination is more liable to occur on high-speed printing, and since an ink becomes softer, transfer area ratio exceeds 100%, and resolution is lowered. On the other hand, if the amount of the ester is in excess of the weight ratio range, the properties of the ester are displayed predominantly over the properties of the wax, so that the ink becomes harder, the coefficients of expansion and contraction of the ink become higher, and the transfer area ratio becomes too low to obtain clear prints.

In this case, the recorded digital video signal V6 is completely erased and the recorded digital audio signal A6 is preserved in a the audio data recording part 6.

IPC: C22C38/00
Filed: 1982-03-12
Abstract: PURPOSE:To prevent deterioration in the characteristics of a sintered Fe alloy contg. dispersed graphite and increases in the extent of wear and the coefft. of friction in accordance with use, by forming hardened Fe-Cu layers between the matrix of the alloy and the graphite particles. CONSTITUTION:Hardened Fe-Cu layers 4 having 3-10mum thickness are formed around graphite particles 2 in a sintered alloy having a structure contg. 1-5wt% free graphite 2 dispersed in the ion matrix 1 contg. <=1.2wt% solubilized carbon. In the figure, each symbol 3 is a pore. The solid lubricity of the alloy is shown by the exposed heads of graphite particles 2 at the surface sliding along its opposite member. The open parts of pores 3 are narrowed during use by the plastic flow 1' of the matrix, yet the layers 4 hinder the graphite particles 2 from flowing in the exposed part of the matrix. As a result, a low coefft. of friction is maintained, and the extent of wear is reduced. The layer 4 are formed by allowing copper plated on the particles 2 with iron as the matrix.

Title: Motor power steering device
Inventor: HOSHINO KENJI
IPC: B62D5/04
Filed: 1985-02-27
Abstract: PURPOSE:To improve the steering feeling by providing an electromagnetic powder clutch the exciting current of which is controlled through the steering load signal in the power transmission path of motor in motor power steering system for vehicle. CONSTITUTION:The steering load signal to be detected through a steering sensor 7 is fed to a controller 18. The controller 18 will drive D.C. motor 8 to steer the handle shaft 6 through friction wheels 10, 12, reduction gear 15, electromagnetic powder clutch 16 and reduction gear 17. Said clutch 17 is employing magnetic powder as frictional medium and constructed such that the transmission torque and the exciting current will be proportional. Consequently, when the controller 18 will feed the exciting current with correspondence to the signal from the steering sensor 7, the transmission torque will vary in proportion to the steering load. With such arrangement, assisting force corresponding with the steering load can be applied onto the handle shaft resulting in improvement of steering feeling.

Abstract: PURPOSE:To prevent a pipeline from being delayed by removing an useless cycle generated after a branch instruction at the time of time-sequentially execut ing the pipeline processing of plural tasks. CONSTITUTION:If the instruction of an address 'X+1' in a CPUO is a branch instruction (JMP) at the time of time-sequentially executing the pipeline processing of two tasks (CPUO, CPU1) in parallel, a branched address ('XX') is set up on an instruction decoding stage for decoding the branch instruction of the address 'X+1' and the instruction of the branched address ('XX') is fetched on an instruction fetch stage next to the task (CPU0) including the branch instruction concerned. Thereby no useless cycle is generated in the pipeline even when a branch instruction exists. In the case of time-sequentially executing the pipeline processing of N tasks, branched addresses are allowed to set up (execution of a branch instruction) during the period of (N-1) cycles after fetching the branch instruction concerned.
