Title: Clock path control system
Inventor: ASAKURA NORIYUKI
IPC: H04J3/00
Filed: 1993-12-28
Abstract: PURPOSE:To prevent an in-equipment clock from being stopped and all signals from being interrupted by selecting an internal oscillator capable of absorbing destination difference through the stuff operation by an opposite equipment when an in-station clock of both systems is interrupted from a clock supply device in a synchronous digital hierarchy(SDH) communication equipment. CONSTITUTION:Clock interrupt detection circuits 11a, 11b of systems 0, 1 in reception sections monitor an in-station clock having a redundancy from a clock supply device. When both the systems detect interrupt of clock input, a selector 14 is used to select an internal oscillator 15 having a frequency accuracy capable of absorbing difference from the frequency of the in-station clock by using the interrupt signal as a trigger through stuff operation of an opposite equipment. Thus, even when both systems of clocks having a redundancy from the clock supply device are interrupted, an in-equipment clock is supplied to an OH processing section 23 to send normal main signal data to the opposite equipment.

SOLUTION: At the time of manufacturing a syringe 1, a fixing member 8 is preliminarily passed through a piston rod 3, and a hollow barrel 2 is inserted from the base end of a holder body 7 via a seat until the leading edge, of the fixing member 8 comes in contact with a flange 73. Furthermore, the fixing member 8 is moved toward the flange 73 and kept in such a state as externally coupled to an engagement member for commercialization. In this case, the base end 22 of the hollow barrel 2 is clamped and fixed particularly by use of the fixing member 8 and the base end edge of the flange 73. As a result, the holder and the hollow barrel 2 becomes integrated with each other, thereby ensuring extremely easy handling and eliminating a concern about the detachment of the holder.  In addition, an injection needle 11, when secured to a fixing part 72 formed on the inner side of the end of the holder body 7, becomes free from a concern about detachment.

Abstract: PURPOSE:To easily change catch force by providing an adjusting screw advancing and retreating while being in contacting with the coil part of a torsion coil spring, and adjusting the sense of touch of opening/closing operation by rotational movement of the screw. CONSTITUTION:An adjusting screw 12 advancing or retreating while being in contacting with the coil part 9a of a torsion coil spring 9 is fitted to a frame type fitting member 2. By advancing or retreating the adjusting screw 12 while rotationally moving it, the position of the coil part 9a of the coil spring 9 against a cam 10 is changed, the moving territory is changed, and the pressing force of the coil spring 9 against the cam 10 is changed. When the torsion spring 3 is supported with three points, it is supported with four points by adding a point due to the adjusting screw 12. As a result of this, when the screw 12 is tightened, the pressing force of the cam 10 by a torsion bar part 9b becomes strong, catch force becomes strong, and the sense of touch of a door A operation of opening/closing becomes hard. Hereby, the catch force can be changed without changing parts.

Abstract: PURPOSE:To prevent electrification unevenness due to the soiling of a corona charger by actuating a cleaning means in response to a detecting signal when the output voltage of a toner concentration sensor is lower than a fixed value. CONSTITUTION:The toner concentration sensor 13 scans in the axial direction of a photosensitive drum 5 by a reciprocatingly driving means. When an image on a reference density plate is developed and reaches the position of the sensor 13, the scanning is started: When an output voltage according to the density V1 is larger than a prescribed value V2, unevenness more than prescribed value does not exist and the cleaning pad 22 does not move. When the electrifying wire 21 is soiled, then V1<V2, and the pad 22 is driven by a motor 25 to clean the wire 21. The pad 22 is fixed to the moving body 23 sliding in the longitudinal direction of a case 20, and is reciprocated between sensors 26 and 27 by a screw shaft 24 connected to the motor 25. Under this constitution, when the corona charger is soiled, it is immediately cleaned, therefore, electrification unevenness is prevented and a stable image density can be attained.

Inventor: TERADA KAZUO
IPC: E02B7/20
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To easily control irrigation in a basin both upstream and downstream of bag type weir. SOLUTION: A circular arc fastener 4 is provided on a river bed in such a state as projected toward an upstream side and the joint part 3a of a bag type weir body formed out of a twofold flexible membrane 2 is kept in close contact with and fixed to the fastener 4.
