Patent JP-H03152419-A (JP)
Title: Optical encoder
Inventor: ISHIKAWA MASAAKI
IPC: G01D5/36
Filed: 1989-11-10
Abstract: PURPOSE:To make it possible to obtain an output signal of an excellent S/N ratio from a light-sensing means and thereby to enable attainment of a high resolution by bringing a pulse plate and an auxiliary pulse plate into contact with each other by actuation so that they can move sildable in part. CONSTITUTION:When a pulse plate 1 rotates in relation to a case body 4, a light flux passing through light-transmitting parts of both of the pulse plate 1 and an auxiliary pulse plate 3 with the rotation of the pulse plate, out of ones emitted from a light-emitting means 6, is detected by a light-sensing means 7. The light-sensing means 7 generates a photocurrent according to the quantity of an incident light and this photocurrent is converted into a pulse voltage by a prescribed electric circuit. By counting the number of these pulses, the amount of rotation of the pulse plate 1, i.e. the amount of rotation of an object of measurement, is determined. The base of the pulse plate 3 is constructed of a member having a spring property and the plate is brought into contact with the pulse plate by the actuation thereof so that it can move slidably in relation to the pulse plate. Therefore, it can be prevented effectively that an unnecessary light flux passes through the light-transmitting parts of the pulse plates 1 and 3, goes around them and enters the light-sensing means 7.

Filed: 1990-10-30
Abstract: PURPOSE:To securely prevent toner from soiling a hand and a machine inside by moving a needle protrusion by operation from the outside and piercing the protrusion into a sealing member which is provided at the opening of a toner container to make a hole, when the toner is supplied from the toner container. CONSTITUTION:By pushing a button 6 for a seal opening means 5 provided at the upper part of a toner container 1, a needle protrusion 20 installed at the end of a shaft 12 is pierced into a sealing member 10 to make a hole. As the sealing member 10 is stretched with expansive material at some tension, the hole is made at one place and then is enlarged, through which the toner in the toner container 1 is supplied inside a developing equipment 22. That is, the sealing member 10 provided at the opening 8 of the toner container 1 is set free by operation from the outside without pulling the sealing member 10 by hand in toner refill, to perform toner refill. It is thus possible to prevent toner from soiling a hand or a device inside.

Title: Releasing agent coating device
Inventor: SENBON IKUROU
IPC: G03G15/20
Filed: 1988-11-18
Abstract: PURPOSE:To apply a releasing agent uniformly around the outer peripheral surfaces of a couple of heat rollers by making the press-contacting part of a porous member where a rollers is pressed thicker than any other part. CONSTITUTION:The releasing agent coating device 1' presses the porous member 4, dipped partially in a releasing agent 3, against the outer peripheral part of the roller 9 to apply the releasing agent to the couple of fixing heat rollers 20 through the roller 9. The press-contacting part 5 of the porous member 4 where the roller 9 is pressed is made thicker than any other part. Thus, the press-contacting part 5 is thicker than any other part, so even if the part is pressed by a spring 7 through a pressure member 6, it contains oil 3 as much as or more than any other part which is not compressed. Consequently, the releasing agent 3 is applied uniformly to the roller 9 and further the outer peripheral surfaces of the fixing heat roller couple 20.

Abstract: PURPOSE:To shorten the operation time and to prevent a wind-up phenomenon by changing the limit value of an input limiter in accordance with the output of an integrator of an advance/delay circuit and limiting the output of the advance/delay circuit to the prescribed value. CONSTITUTION:The algorithm of an advance/delay circuit 7 is composed of an addition circuit 10 consisting of a proportion circuit and an integrated circuit 9. An input limiter 14 is provided to the input of the circuit 10. Then the limit value of the limiter 14 is changed to the value obtained by dividing the differ ence between the limit value of an output limiter 11 and the output of the circuit 9 by the gain of the circuit 8. Under such conditions, the sum of outputs of both circuits 9 and 8 is always equal to the limit value of the limitter 11 despite of application of a large input signal. Thus, the output of the circuit 9 never exceeds the limit value despite application of a long time. Therefore, the output of the circuit 7 immediately gets out of the output limit value and changes in response to the input signal when the input signal is set again to its small value. As a result, the operating time is shortened and at the same time a wind-up phenomenon is prevented.
