Patent JP-S54111306-A (JP)
Title: Record player
Inventor: SHIMOI MAMORU
IPC: F16H27/08
Filed: 1978-02-20
Abstract: PURPOSE: To prevent the incovenience of continually starting the next 1 turn after a gear wheel has made 1 turn by forming the first gear continuous to the intermesh release side of the toothless part of the gear wheel in imperfect tooth which is short in the radial direction.  
     CONSTITUTION: When it is assumed that the intermeshing of a tooth 10 and a pinion 6 be released, a follow-up pin 9a exists near the end of a heart type cam 1b and therefore the follow-up pin 9a falls into the end of side heart type cam 1b owing to the elastic force of a spring 9b. Whereas, immediate upon releasing of the intermeshing of the gear wheel 1 and pinion 6, the shock produced when the gear wheel  1 rotates by the distance (a) causes a trigger lever 3 to turn counterclockwise.  Then, a starting pawl 7 and the bent part 3a of the trigger lever 3 engage and the  rotation of the gear wheel 1 is again started. Thereupon, a short imperfect tooth 11  is added in the radial direction. Then, the distance at which the gear wheel 1 is  rotated by the spring 9b after the gear wheel 1 and pinion 6 have been released of  intermeshing becomes b(b<a) only and therefore the shock is considerably reduces.

Title: Optical character reader
Inventor: AOKI NAOTO
IPC: G06K9/68
Filed: 1995-02-08
Abstract: PURPOSE: To decrease unreadable characters by composing a character set of subcategories including modified patterns that do not conform to each other among different categories. CONSTITUTION: Subcategories sC of, for example, a category C1 of a character set 11 in a dictionary to the subcategories sC are limited to C1-1 to C1-M. In a category C2, subcategories sC are limited to only C2-1. Thus, the subcategories Sc in the character set 11 are limited so that modified patterns which are similar in shape among different categories C are not present in the character set 11. Consequently, even a character which is obtained by greatly modifying the shape of a standard character and can not read because it conforms with a similar modified pattern of a different category, can be read.

Title: Printing head
Inventor: NISHISU MIKIO
IPC: B41J2/255
Filed: 1990-01-31
Abstract: PURPOSE:To enable reduction of the peak and actually effective voltages of a drive current by arranging printing pins in four zigzag rows in a printing head and at the same time, making an interval between the rows a specific multiple of a reciprocal of dot density. CONSTITUTION:In a printing head for a dot impact system printing device, printing pins 1 to 24 are arranged in four zigzag rows and at the same time, an interval between the rows is set equal to 'an integer + 0.25' times of print dot density in each row. For example, when all the twenty four printing pins are used for printing, printing pins R1, R2, L1, L2 of each row are driven in a wavy pattern so that they are delayed sequentially by 2.25 cycles. This is because the printing pins are aligned at an interval of 2.25 [dots]. Subsequently, the total sum of drive currents of the printing pins indicates a wavy pattern 5. Therefore, if the pulse waveform is a 1:1 triangular wave, the average value of the drive current is CX6[A], and the peak value is CX9[A] and the actually effective value is CX0.25[A]. Thus each value of the drive current is significantly reduced.
