Title: Automatic head gap adjustment device of printer
Inventor: KANEKO SATORU
IPC: B41J23/04
Filed: 1990-05-29
Abstract: PURPOSE:To set an appropriate head gap by detecting optically and action until a printing head is allowed to come in contact with the surface of a sheet and driving a motor by the number of steps corresponding to the detection signal to move the printing head backward. CONSTITUTION:When a head gap is adjusted, a printing head 6 descends from a position which is previously set as a reference and detects a distance upto a position where the head 6 comes in contact with a sheet 10, that is, a distance upto a zero position as a pulse count. This pulse count is entered in an auxiliary control part 52. Then this auxiliary control part 52 counts a detected pulse entered from a rotation detection part 55. The auxiliary control part 52 drives a motor 24 by the number of steps corresponding to the count at the time of a zero position detection, and moves the printing head 6 backward over a specified distance. Thus a specified gap G is set between the sheet surface 10 and the tip 6a of the printing head 6.

Filed: 1987-05-29
Abstract: PURPOSE:To omit a resistance element heretofore externally attached and to reduce a circuit configuration by forming a resistance element in series with a diode element on the same chip. CONSTITUTION:A structure in which a resistance element 3 is internally connected to the anode terminal A of the diode element 2 of a diode 1 containing a resistor therein on the same chip is formed. For example, in case of a filter circuit 11, it has a property that, when a forward current flows, the resistive component of the element drops. When the diode 2 is turned ON (biased positively to +B) by utilizing this property, an inductance L2 is short-circuited, the inductance of the circuit 11 becomes only an inductance L1. When the diode 2 is turned OFF (not biased to +B), the inductance component of the circuit 11 becomes the sum of the inductances L2 and L1.

Abstract: PURPOSE:To save the pump driving energy of an anti-skid function activating pump by enabling said pump of being driven by means of an electrically powered motor and placing the motor under control of a computer to have the motor driven only while the anti-skid function is operated. CONSTITUTION:As following to the stepping action on a brake pedal 10c, a switch mechanism 21a is actuated so that speed of wheels is calculated on the basis of a signal sent from a sensor 18 inside a computer 21. On the other hand, inside the computer, an ideal controlling condition is computed to derive a reference wheel speed.

Once the actual wheel speed becomes lower than the reference value, the computer 1 refers such state to the skid state and then generates the signals for turning on a motor 23, opening a primary solenoid valve 120 and closing a solenoid valve 121. A liquid pressure from a pump 24 will then induce a piston 108 to move left so that pressure of a brake liquid is lowered.

Abstract: PURPOSE:To attain simple and clear program description by expressing indentation by a graph such as lines having priority and processing the indentation expression so that functions are divided in accordance with the priority. CONSTITUTION:Retrieving description in priority lines C0-C8 and detecting the description, an object code forming means sets up '1' in a corresponding bit B0 of a priority register. Retrieving description in an end line C9 and detecting the description, the forming means discriminates the end of the program, and if the program is not ended, discriminates whether the priority line is higher or lower than the current order line. When a line 2 is lower than a line 1, termination processing is not executed and the succeeding line is included in the function of the current line. Since the line 2 is described in the priority line C1, '1' is set up in the succeeding bit B1 concerned in the priority register and the description in the end line C9 is retrieved. If the succeeding higher priority line is described, the termination processing of the program function for the number of bits '1' which is less than the number of bits corresponding to the priority line while referring the priority register to clear bits less than the one corresponding to the priority line of the register.

Abstract: PURPOSE: To prevent the charge current of a  field relaxation layer from partially  concentratedly being applied by setting up a mean pressure zone with the resistance  value which is lower than that of a low resistance corona shielding layer on the  field relaxation layer which is adjacent to the low resistance corona shielding layer.  
     CONSTITUTION: The ends of the low resistance corona shielding layer set on the insulated layers 5a and 5b of the winding ends 3a and 3b in a stator winding are inclined by θ so as to be opposed to each other and mean pressure zones 9a and 9b with the resistance value which is lower than that of the low resistance corona  shielding layers 6a and 6b are set on the field relaxation layers 7a and 7b which are  adjacent to 6a and 6b. The angle of mean pressure zone is smaller than the  angle  α of equipotential line 10 on the surface of the field relaxation layer and larger than  the angle θ. Since this permits the charge current applied in the field relaration  layer 7 to scatter like the arrow, it can be prevented from being partialy  concentratedly overheated.

This can solve by a single technical effort the problems of scaling, increased use of chemicals, increased amt. of sludge and an unstable defluorination performance. Since the process of removing calcium can also be omitted, the device and process can be simplified.
