Title: Drive device of thermal head
Inventor: HASHIGUCHI TAKUJI
IPC: B41J2/355
Filed: 1990-09-08
Abstract: PURPOSE:To prevent the occurrence of a state where ink runs in an image and improve image quality by selecting drive parameters for a thermal resistor based on print data at an image printing area where an image is already printed in the surroundings which are likely to give a comparatively significant influence to an area to be printed. CONSTITUTION:Print data A1,..., A(i-1), Ai, A(i+1),..., An relative to a single line where an image is thermally printed using thermal resistors R1 to Rn are stored in a latch circuit 6. In addition, print data B1,..., Bi,..., Bn which are a single line ahead and print data C1,..., Ci,..., Cn which are two lines ahead are stored in latch circuits 7, 8 respectively. Then an energizing power for a highlighted pixel Ai by which an image is printed in a line l currently in the process of data printing, that is, a drive period of the thermal resistor Ri corresponding to the highlighted pixel Ai, is determined. In this case, attention is given to four pixels such as pixel Bi corresponding to the mentioned highlighted pixel Ai in a line l1 which is a single line ahead, pixels B(i-1), B(i+1) corresponding to pixel Bi and adjacent to a position before and after a main scan direction, and appropriate pixel Ci in a line l2 which is two lines ahead. Finally, the mentioned drive period in the highlighted pixel Ai is determined based on the print data of these reference pixels.

IPC: H03M1/04
Filed: 1987-09-24
Abstract: PURPOSE:To improve the resolution by adding a sinusoidal wave signal having a prescribed frequency and a level to an input analog signal. CONSTITUTION:An output clock CLK of a clock generator 5 is processed by a frequency divider 11 and a BPF 12 to obtain a sinusoidal wave signal SSI having a frequency being 1/(2n+1) of the sampling frequency of an A/D converter 4 and a level being 1.5 time or over the analog level corresponding to the least significant bit of the output of the A/D converter 4.

IPC: H04N5/63
Filed: 1985-10-25
Abstract: PURPOSE:To prevent the wasteful electric power consumption due to the forgetting of the turning-off of an electric power source by interrupting automatically the electric power source circuit when a composite video signal is stopped like the completion of the television broadcasting. CONSTITUTION:When a synchronizing detecting circuit 11 receives a vertical synchronizing signal Vs, a transistor TR synchronizes with the synchronizing signal Vs and repeats ON and OFF. A capacitor C repeats the charging and the discharging in accordance with the ON and OFF of the transistor TR. By completing the broadcasting, the input of the synchronizing signal Vs is stopped, and then, the transistor TR is fixed to the off condition, as the result, a charging voltage Vc of the capacitor C rises to the threshold or above specified beforehand. When the voltage of the threshold or above is inputted, an inverter INV inverts the output and outputs it to a relay driving circuit 121. The relay driving circuit 121 operates a relay circuit 122 and changes over an electric power source circuit 13 to the off condition.

Title: Image reader
Inventor: FUKUSHIMA ITSUKI
IPC: H04N1/04
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an image reader, capable of reading an image less in granurality by providing a reflection means or the like that reflects part of a lighting light in the direction toward the outside of the incident range and extends in the lengthwise direction of the cross section of an illuminating light. SOLUTION: A rod 261 and a diffusion plate 263 which are the components of an optical conversion means convert light from a light source lighted as a spot into the illuminating light with an almost rectangular cross section and emits the illuminating light towards an original 1. An image forming lens 24 forms the image of the light from the original 1 made incident onto an incident range. A CCD23 photoelectrically-converts light formed by the image forming lens 24 into an image signal. A mirror 264 as a reflection means extended in the lengthwise direction of the cross section of the illuminating light reflects part of the illuminating light in the direction towards the outside of the incident range.  In this image reader, although indirect lighting light passing through a transparent original 1 receives image information and granurality information, most of the indirect lighting light goes straight ahead and is not made incident on the pupil of the image forming lens 24, most of the indirectly illuminating light passing through the transparent original 1 does not enter the light receiving section of a CCD23.

Title: Single-screw grinding and polishing grain-milling machine
Inventor: NAKAMURA KAZUO
IPC: B02B5/02
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized and inexpensive single-screw grinding and polishing grain-milling machine. SOLUTION: In a single-screw grinding and polishing machine 10, spiral ridges 40A are formed to the peripheral of a grinding rice milling roll 40 and abrasive grain 40B are fixed thereto. A polishing grain-milling roll 56 having parallel ridges 56A formed to the peripheral surface thereof is integrally connected to the lower part of the grinding grain-milling roll 40 on the same axis and a motor is connected to the lower part of the polishing grain-milling roll 56. Since feed force can be applied to grain in an axial direction by the spiral ridges 40A of the grinding grainmilling roll 40, the blocking of grain on the periphery of the grinding grain-milling roll 40 can be suppressed.  By this constitution, the peripheral speed of the grinding grain-milling roll 40 may be almost same to that of the polishing grain-milling roll 56 and, therefore, the single grinding and polishing machine 10 can be made inexpensive because of only one motor and the diameter of the grinding grain-milling roll is made same to that of the polishing grain-milling roll 56 to miniaturize the single-screw grinding and polishing machine 10.

Title: Recording medium-driving device
Inventor: SHIBATA TAKEYA
IPC: B43L13/00
Filed: 1994-09-08
Abstract: PURPOSE: To facilitate the adjustment of pressing force by a method wherein a first adjusting member is adjusted on the basis of the first position of a coiled spring supporting member and a second adjusting member is adjusted on the basis of the first adjusted member. CONSTITUTION: Since a coiled spring supporting member 40 is located at a first position, at which the coiled spring supporting member 40 abuts against the standard member 220 of a pinch roller supporting member 22, in order to adjust a first pressing force, the position is employed as the basis. By moving a first adjusting member 34 backwards and forwards, the length of a coiled spring 33 is changed. Under the condition that the pinching force between a pinch roller 20 and a driving roller 50 is measured with a proper measuring means, the first adjusting member 34 is fixed at the position, at which the first pressing force is generated. The adjustment of a second pressing force is performed on the basis of the first adjusting member 34.  By actuating a pressure changing-over lever 43, a coiled spring supporting member 40 is positioned to a second position, at which the coiled spring supporting member 40 abuts against a second adjusting member 35. Under the state just mentioned above, by moving the second adjusting member 35 backwards and forwards, the length of the coiled spring 33 is changed and, after that, the member 35 is fixed to the desired position, resulting in allowing to easily adjust to obtain the second pressing force.
