Title: Automatic tensioner
Inventor: MITOBE NORIO
IPC: F16H7/12
Filed: 1988-04-21
Abstract: PURPOSE:To prevent the tooth skip of a timing belt by providing such a constitution that the stopper part on the movable eccentric member side is struck with the stopper part on the fixed member side and stopped, when the tension of the belt is increased to rotate the movable eccentric member. CONSTITUTION:When an engine is stopped, a crank shaft rotates reversely for a moment, and the tension on slack side of a belt 27 to which an automatic tensioner is installed is increased. At that time, an eccentric member 18 rotates in the direction leaving the timing belt 27 (counter clockwise in the attached drawing), but it is stopped after rotating to some degree, as the stopper part 22b of a blacket is struck with the stopper part 14c of a second side plate (the engaging part 14b of which is engaged with the pin 16 of a fixed part). Therefore, the eccentric member 18 is never stopped with rotating largely in the direction leaving the belt 27. Thus, when the engine is then started, no tooth skip of the belt 27 is caused even if the belt 27 is rapidly loosed on the slack side, and engine troubles caused by this tooth skip can be prevented.

Filed: 1978-08-15
Abstract: PURPOSE: To control image making speeds amd obtain the fog-free images of required densities by changing the voltage and polarity of a low voltage source with a changeover switch.  
     CONSTITUTION: An electrode 3 having a photoconductive layer 1 and an electrode 4 for applying voltage are held at a spacing of about 20 to 500μ and the developing solution composed primarily of the insulation type organic solvent containing charged toner 6 is put therebetween. First, if a changeover switch 7 is set at the shortcircuit contact 17a, the charged toner 6 disperses evenly in the developing solution. Next, when the switch is changed over to the high voltage application contact 17b and exposure is done, then the toner 6 having been charged to plus polarity moves to the surface of the photoconductive layer 1 and deposits thereon. When the switch is changed over to the low voltage application contact 17c and a voltage of several V to 1000V is applied between the electrodes after this, then the toner images are formed on the surface of the substrate 5. Next, when the switch is changed over to 17d, then the electrodes 3, 4 are electrically cut off, due to which the formation of the toner image is suspended, whereby the toner images of nescessary densities are obtained.

Title: Optical detector
Inventor: SEKIKAWA TADAHIKO
IPC: G01V8/12
Filed: 1990-04-16
Abstract: PURPOSE:To execute detection free from mistake by giving hysteresis to the detection of the presence or absence of an object or the position thereof by lowering a reference level at the time of transition from noninterception of light to interception thereof and by raising the reference level at the time of transition from the interception of light to the noninterception thereof. CONSTITUTION:When there is no interception of light by an object, a selector switch 8 is connected onto the side of a light interception reference power source 9 and a light interception reference level Vfl of low reference is given as a reference level of a comparator 7. When there is interception of light by the object and an input of the quantity of a scanned and received light to the comparator 7 turns lower than the light interception reference level, at this time, an output of the comparator 7 is switched over from low to high. A microprocessor (MP) 3 detects a change in the output of the comparator and outputs a switching signal to the selector switch 8. The switch 8 changes over the connection with the comparator 7 onto the side of a non-light-interception reference power source 10 and a non-light-interception reference level Vfh of high level is given to the comparator 7. In the case when the object transfers from the state of interception of light to that of noninterception of light, the output of the comparator 7 is switched over from high to low, and the MP 3 discriminates transition from the interception of light to the noninterception of light on the basis of the change in the output of the comparator and outputs the switching signal to the switch 8.
