Title: Bicycle wheel suspension device
Inventor: POORU ETSUCHI TAANA
IPC: F16F9/16
Filed: 1993-04-06
Abstract: PURPOSE: To absorb an impact of a road but not to absorb pedaling energy by providing a means for preventing a compression of a suspension assembly in association with a pedal depressing action of a fluid circuit means for controlling the compression of an expansion assembly but allowing compression based on the impact from a ground surface. CONSTITUTION: A damper valve (fluid valve means) 60 is engaged with a lower side of an upper expansion tube 44 to control a flow of viscous fluid 62 between both chambers 53 and 57 as one fluid circuit means. The valve 60 has a vent port 64, which is closed by a valve plate 66, which is held in a closed state by a compression spring 68. A tray hole part 72 generates damper characteristics having a large resistance when a pedaling force is given together with the spring 68. Accordingly, when collided with a protrusion of a road, compression loads are generated by suspension assemblies 40 to urge through the port 64 of the means 60 by a strong pressure from the plate 66 pressed by fluid spring of the chamber 53, and hence the fluid flows to the chamber 57 of the tube 44.

Title: System for deciding repetitively quantization interval of a/d converter
Inventor: DAGDEVIREN NURI RUHI
IPC: H04L27/00
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a MODEM capable of selectively adjusting signal level corresponding to a quantization interval decided repetitively by an A/D converter. SOLUTION: The system is used with a central communication equipment 170 coupled digitally with a digital communication network including an analog interface having an A/D converter (ADC) 210 and decides repetitively a quantization interval of the ADC. A signal generator coupled with the input of the ADC generates a sequence of analog signals to be quantized by the ADC to obtain a symbol obtained as a result of reception by the central communication equipment. The central communication equipment receives a return signal. The return signal indicates the comparison between the symbol and a predicted symbol. A threshold level between quantization intervals of the ADC is decided by an analyzer in this comparison.

Abstract: PROBLEM TO BE SOLVED: To provide a sufficient air tightness holding function and a sufficient lubricating oil adjusting function by combining two of a first and a second rings, which are respectively formed by forming a steel wire into an annular shape having an abutment part at a part thereof. SOLUTION: A piston ring R is formed of a first ring 1, which is formed by forming a steel wire having a L-shaped cross section into an annular shape having a stage part (g) in the peripheral side thereof, and a second ring 2, which is formed by forming a steel wire into an annular shape having an outer diameter larger than the outer diameter of the first ring. When both the rings 1, 2 are fitted in a ring groove G of a piston P in the condition that abutment parts thereof are displaced from each other so that they are not overlapped with each other, the inner peripheral surface of the first ring 1 pushes a bottom surface of the ring groove G with elasticity thereof. The outer peripheral surface of the second ring 2 pushes the inner peripheral wall surface of a cylinder C with elasticity thereof for installation. With this structure, generation of a passage of gas leak is prevented.

Title: Rolling method in the shortest time with reverse mill
Inventor: OONOYA KOUICHI
IPC: B21B37/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To improve production efficiency by shortening reversing time from the release of a preceding pass till the biting of the next pass in the automatic reversing operation of a reverse mill such as the hot rolling of a thick plate. SOLUTION: The finish time ts of screw-down positioning is determined from the changing amount (x) of the screw-down location from the present screw-down location of a roll to the screw-down location of the next pass. In case that this ts is larger than a specified value, deceleration of rolling speed V is started when the remaining length of the material to be rolled which is in rolling at this time becomes a prescribed length L1 , the change of the screw- down location of the roll is started at the point of time when the material to be rolled is released from the roll and, after stopping the material to be rolled, the material to be rolled is reversed so that the finish timing of the screw-down positioning of the roll is made to coincide with the biting time of the material to be rolled in the next pass. In case that the ts is smaller than the specified value, when the remaining length of the material to be rolled becomes the prescribed length L2 , the deceleration is started and reversing is executed subsequently to this deceleration.

Filed: 1984-04-20
Abstract: PURPOSE:To make it possible to automatically and properly detect entry completion of character entry to one frame by detecting whether or not another stroke is entered on the said frame while a fixed time passes from a stroke end. CONSTITUTION:When one stroke input is completed, an input pen 2 is separated from an entry surface 10 of a tablet in a tablet device 1 and a stroke switch is turned off. From then, a timer is turned on and recognition is treated. In this process, while coordinate data are fetched and when the stroke switch is always turned on/off in parallel, and in the parallel treatment process, it is confirmed by a character recognition unit 3 that the stroke switch is on, a frame position of a character entry frame 11 and a coordinate value in the frame are calculated again, and when it is located in the same frame as an already inputted stroke, recognition treatment is once stopped and input processing of a next stroke is executed again. For another frame, it is looked on as that a character input of a previous frame is once completed.
