Abstract: PURPOSE:To relax a shock when a hydraulic actuator is operated rapidly and also to improve driving operation ability, by providing a throttling part for a line to be connected to the one side pilot port of a pilot selector valve and by setting a check valve for pilot operation in parallel to it. CONSTITUTION:When raising operation for hydraulic excavator boom is carried out, by operating the operation lever 26 of a remote control valve 19 for the boom in (A) direction, pilot pressure from a pilot pump 17 acts upon a pilot port 23, by opening a pilot valve 25, a pipe line 27', a throttling part 29 and a check valve 30 for pilot operation. When the operation lever 26 is suddenly and rapidly operated to the neutral on the way of raising operation for the boom, the pilot pressure is interrupted by the pilot valve 25, the line 27' is communicated to an oil tank 18 through the pilot valve 25 and the pilot check valve 30 comes in closed state. As the result, the inner pressure on the pilot port 23 side is released slowly through the throttling part 29 and the changeover operation of a boom valve 11 is carried out slowly.

IPC: G03G15/14
Filed: 1985-11-26
Abstract: PURPOSE:To eliminate a flaw in a photosensitive body due to a separation pawl and to separate transfer paper from the photosensitive body securely by providing a means which forms a toner pattern image on the photosensitive body where the tip of the separation pawl is in contact with the photosensitive body outside its image formation range. CONSTITUTION:A latent image is developed by a developing device 10 to form a toner image, which is transferred to transfer paper 5 by a transfer charger 8. Then, the transfer paper 5 is separated by the separation pawl 7. The separation pawl 7 contacts the photosensitive body 9 right before the head of the transfer paper 5 passes the separation pawl part and the tip 7a of the separation pawl is introduced into between the transfer paper 5 and photosensitive body 9 when the head of the transfer paper comes, thereby separating the transfer paper 5 from the photosensitive body 9. When the toner pattern image rotates on the position of the separation pawl, the tip 7a of the separation pawl 7 is brought into contact with the photosensitive body 9 across the toner pattern image. The separation claw 7 is lubricated sufficiently with toner and the photosensitive body 9 never flaws because of toner sticking on the separation pawl even after a toner pattern image 6 is passed.

Title: Input buffer circuit
Inventor: UEMATSU AKIRA
IPC: H03K19/0185
Filed: 1990-10-02
Abstract: PURPOSE:To obtain the logic level of an input buffer circuit with low fluctuation of manufacturing condition by constructing a level circuit of N-channel MOS transistors of the same channel length. CONSTITUTION:N13 transistors are formed by vertically connecting transistors of the same channel length as that of an N12 transistor in multiple stages. Therefore, the channel length size of the N13 transistor is set equally to that of the N12 transistor, and also, the capacity of the N13 transistor can be set lower than that of the N12 transistor. Furthermore, since the capacity of the N12 and N13 transistor can be shifted at the same ratio, potential at the output point 1 of the level circuit consisting of the N12 and N13 transistors can remain unchanged for the fluctuation of channel length. Thereby, it is possible to suppress the fluctuation of the logic level VGL.
