Title: Device for automatically controlling toe angle of vehicle
Inventor: SAKAMOTO TOSHIHARU
IPC: B62D17/00
Filed: 1988-02-01
Abstract: PURPOSE:To enable high speed and accurate control by controlling a toe angle through oscillations of an oscillating arm with expansion and contraction of a cylinder and rotation of a toe angle control rod, thereby performing operation at a high speed at the time of full stroke mode of the arm while at a low speed at the time of other oscillation modes. CONSTITUTION:In a device where the length of a lateral link is expanded and contracted by rotating a toe angle control rod 950 around the axial line, thereby a toe angle is changed, the rod 950 is provided at a clamp-free oscillation arm 952, which is oscillated by a cylinder 953. In performing toe angle control operation, required oscillation times of the arm 952 is computed by means of an operation means 956 based on an actual toe angle value and a toe angle value set. At the time of oscillations caused by full stroke mode of the arm 952, a cylinder 953 is operated at a high speed, and at the time of other oscillations than the former, it is controlled to be operated at a low speed by means of a cylinder speed control means 957.

Abstract: PURPOSE:To obtain the distinct cipied images corresponding to the images of different gradation characteristics by providing a means of suitably changing the thickness, shape and charging amount of the toner layer coated and charged on a developing roll to the chargint and coating member of the developing device. CONSTITUTION:A charging and coating member 4 is held by a guide plate 5 and is made vertically movable along this guide 5. At the upper end thereof, it is supported by a leaf spring 6, this leaf spring 6 being held at a fulcrum 7. In this way, a means which consists of the guide 5 and leaf spring 6 and changes the contact pressure upon the developing roll 1 is provided to the charging and coating member 4. Now, when the contact pressure is increased, the toner layer 3a on the developing roll 1 becomes relatively thin and this is suited for the reproduction of soft gradation images such as of photographs. Conversely, when the contact pressure is lowered, the toner layer 3a on the developing roll 1 is relatively thick and suited for the reproduction of images of hard gradation such as line drawings. In this way, the distinct copy images corresponding to the images of different gradation characteristics may be obtained.

The infrared rays are outputted into an amplifier 13. Meanwhile, the infrared rays from the light source 1 become the infrared rays, which do not include the absorbing wavelength of the component gas to be measured with a comparison filter 4a. The infrared rays enter into. a pyro- sensor 5a. The infrared rays are outputted into an amplifier 12 after passing the sensor 5a. Finally, the difference between the outputs of the amplifiers 12 and 13 is detected with a comparator 11, and the concentration of the component gas to be measured in the gas to be measured is measured.
