Patent JP-H01256715-A (JP)
Title: Gas regulator
Inventor: HONMA NOBUYUKI
IPC: F23N1/00
Filed: 1988-04-05
Abstract: PURPOSE:To dampen a variation in pressure in a controlling chamber so as to prevent hunting by a method wherein a plug is provided with a throttled hole communicating an interior part of an accumulator with the controlling chamber and volume of an accumulator and a hole diameter of the throttled hole are properly selected. CONSTITUTION:A plug 22 divides a controlling chamber 7 and an interior part of an accumulator 21 and the plug is formed with a throttled hole 23 for communicating the controlling chamber 7 with the interior part of the accumulator 21. That is, the controlling chamber 7 and the accumulator 21 communicate with each other through the throttled hole 23 of the plug 22 and then variation in an inner pressure of the controlling chamber 7 is damped. Even if a boosted pressure of a turbo-charger 28 acting as a pilot pressure is rapidly varied, a variation of an inner pressure in the controlling chamber 7 is dampened. As a result, even if a flow rate of gas fed out of a space 14 is less in volume, a so-called hunting phenomenon in which a valve 3 repeats its ON or OFF states to make an intermittent supplying of gas to a mixer 29 is not generated, a constant speed rotation of a gas engine 26 is kept and then an output frequency of a generator 30 is accurately kept at the predetermined value.

Filed: 1990-03-31
Abstract: PURPOSE:To obtain uniform, effective and sufficiently high copied image density by using resin as a matrix component and dispersing at least one of titanium black and magnetic iron oxide to constitute a conductive layer. CONSTITUTION:In order to produce the conductive roll, one or both of titanium black and magnetic iron oxide which are conductive materials are blended into phenolic resin to a matrix component, mixed and agitated to form a mixed resin solution consisting of the conductive material. The mixed resin solution is stored in a tank 13 as a dipping solution. Then a core bar is vertically set up and repeatedly dipped into the mixed resin solution to form a conductive layer on the outer periphery of the core bar 12. The solvent is removed by drying it and the phenolic resin is cured by heating to form a conductive layer 14. Since the conductive roll formed by this procedure is used as a developing roll, uniform copied pictures can be obtained without generating uneven images or the like and sufficiently high image density can be obtained.

Title: Channel-clock information recovering apparatus
Inventor: KORNELIS A IMMINK
IPC: H04L7/02
Filed: 1987-04-09
Abstract: A sampled synchronous transmission signal Vt is represented by a series of samples J at equidistant sampling instants. A computing circuit 5 computes the positions R of the sampling instants relative to the rising edges of a virtual reference clock Cref which is phase-locked to the channel clock. For each sampling instant the position R is determined on the basis of the position R of a preceding sampling instant and a measure Q of the difference in time between the sampling interval T and the period L of the virtual reference clock Cref. From the values of the successive samples J an interpolation circuit 2 derives the positions N of the detection-level crossings by the transmission signal Vt, which crosssings represent a fixed phase position of the channel clock. After each detections-level crossing the measure Q of the time difference is corrected by means of circuit 3 and 4 depending on the difference between the positions N and R. A data recovery arrangement recovers the data depending on the values determined for the positions R.
