  • Patent number: 6493298
    Abstract: A method for controlling reproduction speed of an optical disk is disclosed in which when a data recorded in an optical disk is read, stored and transmitted to a connected instrument through a digital interface, the speed in reading and reproducing the data recorded in the optical disk is controlled to be varied at a high speed or at a low speed according to a transmission rate or a residual amount of the stored data. By doing that, the output image is prevented from temporary pausing and noise images such as a flicker is originally prevented from outputting.

  • Patent number: 6491011
    Abstract: To provide a valve system for an engine, in which a valve stem for an engine valve is slidably fitted in a guide cylinder provided in a cylinder head. A rocker arm is interlocked to rock with rotation of a camshaft. The rocker arm is also interlocked with the valve stem. With the above construction, local wear, galling, and the like in the guide cylinder can be prevented. Accordingly, the reliability can be improved. A lifter is interposed between a rocker arm and a valve stem. The lifter is formed into a cylindrical shape with a closed bottom and has a diameter larger than an outside diameter of the valve stem. The lifter is fitted in a lifter housing in such a manner as to be slidable in the axial direction of the valve stem. The lifter housing is fixed to a cylinder head.

  • Patent number: 6493404
    Abstract: An analog input signal that is sampled at a predetermined rate is multiplied by a corresponding binary code sequence, i.e. “+1” or “−1” by the multiplier. The output of this multiplier is applied in conjunction with a signal supplied by the negative feedback circuit to the analog integrator. The quantization circuit quantizes the output signal of the analog integrator into N levels and outputs a digital word. This digital word is delayed by a unit time interval by a digital delay circuit and then processed by the above mentioned negative feedback circuit. As a result of this signal magnitude reducing process, the required integrating capacitance can be minimized without risks of saturation effects. Additionally, the output is already in digital form as required by the subsequent system blocks.

  • Patent number: 6491458
    Abstract: A printing system includes a printing apparatus and a computer. The printing apparatus and the computer each include a density setting section. The printing system further includes a data processing section, which is at least adapted to transfer printing density data for a predetermined printing object from the computer to the printing apparatus so as to set printing density on the printing apparatus and to transfer printing density data for a predetermined printing object from the printing apparatus to the computer in order to store the printing density data in a database. Since printing density can be set on either of the printing apparatus and the computer, for example, in a trial printing mode, printing density data are transferred from the database stored in the computer to the printing apparatus so as to set printing density on the printing apparatus, thereby enabling trial printing.

  • Patent number: 6490950
    Abstract: A set of driver bits for Robertson screw fasteners includes driver bits (10a-d) whose shaft bodies (12a-d) have distinctive markings thereon corresponding to respective sizes of working tips (14a-d) of the driver bits. These distinctive markings are consistent throughout a family of sets. In one embodiment the distinctive marking are different colors, with each different color corresponding to a working-tip size. The colors are applied only to shaft bodies (36a-d) of some of the driver bits by plating the shaft bodies with zinc layers (22) and then dying the outer surfaces of the zinc layers with color dye (24). This coloring is carried out before the shaft bodies are connected to their respective working tips. Once the outer surfaces (20) of the shaft bodies are thusly colored, the respective working tips are swaged to the shaft bodies to thereby form color-coded Robertson driver bits.

  • Patent number: 6492994
    Abstract: Upon composing characters with an image, character images in an image for editing and in a composite image agree. When characters are composed with a low resolution image represented by low resolution image data, character image generating means generates enlarged character image data from a character image to be composed with, and 1/n reduction means obtains reduced character image data by reducing the enlarged character image data by 1/n. Editing means generates an image for editing by using the reduced character image data and the low resolution image data. The editing procedure and the enlarged character image data are recorded in an editing description file. Based on the editing description file, composition means in an image server generates composite image data by using the enlarged character image data and high resolution image data. The composite image data are output as a printed image by image outputting means.
