Filed: 1993-06-08
Abstract: PURPOSE:To secure a vehicle suspension system that has improved the extent of controllability in correcting any slippage in phase due to filtering by comparing the reference value of a period for a varying waveform of a damping characteristic control signal with the detected value, and performing such compensation control as adding or subtracting a value of the control signal. CONSTITUTION:This suspension system is provided with a control means (e) having a damping characteristic altering means (a) to be interposed between a car body and each wheel, a car behavior detecting means (c) and a damping characteristic basic control part (d) controlling a damping characteristic optimally on the basis of the signal found out of the car behavior detected value. In succession, a period detecting means (f) of varying waveforms in the control signal is compared with a period and reference period of this varying wave form in the control signal, and when the period of the varying waveform in the control signal is longer than the reference period, a specified value is added to this control signal, and when it is shorter than that, such a compensation control part (g) as subtracting the specified value from the control signal is installed there. With this constitution, any slippage in phase due to filtering of the control signal is corrected and thereby controllability is thus improvable.

Filed: 1986-06-13
Abstract: PURPOSE:To display a picture on any position of a panel sheet on the same condition by forming a spiral cooling pipe on the rear face of a transparent substrate so that its density is lower toward the peripheral part from the center and keeping the temperature distribution uniform on a liquid crystal panel. CONSTITUTION:A liquid crystal 9 in a part corresponding to the intersection between electrodes 13 and 14 shown in a figure (a) is heated by applying a voltage to both electrodes to display a desired picture on a liquid crystal panel 2. If a light source 3 shown in a figure (b) is lit then, its illuminating light is diffused up to the full size of a condenser Fresnel lens 6 by a lens 4 and is projected to the panel 2 throughout. The light is reflected on the electrode 14 and is condensed again by the lens 6 and is projected to a screen by an image forming lens 8. Since the quantity of light of the light source 3 is largest on the optical axis, the panel 2 receives heat most in the center. Since a spiral cooling pipe 16 is so formed that its density is lower toward the peripheral part from the center, the cooling action is most powerful in the center to keep the temperature distribution uniform on the panel 2.

Title: Variable speed gear for inclined shaft type axial piston pump motor
Inventor: NAGAHARA GIICHI
IPC: F04B1/24
Filed: 1985-06-26
Abstract: PURPOSE:To shorten the length of a variable speed gear by incorporating the telescopic constitution of a sleeve and a piston fitted therein in an end cover along the swing direction of a valve plate and providing a trunion pin engaging said valve plate in said piston. CONSTITUTION:Pirot pressure acts on sleeves 23a, 23b and a pilot pressure chamber 22a which has volume reduced by the movement of a piston 24 to reduce the pivotable angle of a valve plate 4 from the condition shown in the drawing. Then, the sleeves 23a, 23b and the piston 24 are integrated to be moved by the stroke L1 of the sleeve. When the sleeves 23a, 23b abut against a stopper to be stopped, only the piston 24 keeps moving as it is. It is moved by the stroke L2 to the sleeve and stopped. Since the valve plate is thus swing by the respective strokes of sleeve and piston, the length of a variable speed gear can be shortened under the same condition of swing radius of the valve plate 4 as prior one.

IPC: G06K7/00
Filed: 1979-10-24
Abstract: PURPOSE: To make it possible to perform processing by use of an ordinary signal decoding part by providing a high-speed memory, having two functions of high- speed writing and low-speed reading, between an ITV camera and signal decoding part.  
     CONSTITUTION: A video signal for one horizontal scan from ITV camera 1 is converted by binary-coding circuit 5 into a digital signal, which is written in memory 6 at a high speed. High-speed memory 6, after being stored with bar code information for one horizontal scan, operates control circuit 10 to change the memory lock from the high-speed to the low speed and the memory mode from writing to reading. As a result, the writing operation of memory 6 is changed over to the reading operation and the previously written bar code information is read out at the low speed and sent to signal decoding circuit 7. Thus, the high-speed writing operation and low-speed reading operation are alternated, so that the ordinary signal decoding part can perform the processing sufficiently.

Title: Plastic region fastening bolt
Inventor: MIYAZAKI TOSHIO
IPC: F16B35/00
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To eliminate any necessity of working it by a separate process and reduce the manufacturing cost by providing a first knurled part and a second knurled part having the cross section smaller than a shaft part and a screw part in the shaft part and setting the second knurled part as an extension part. SOLUTION: The cross section of a second knurled part 13 is set to be smaller than other parts, namely, a first knurled part 12, a shaft part 11, and a screw part 8 and therefore has the similar functions to the conventional extension parts. When a bolt 1 is fastened from the head part 10 to a plastic region, the second gnurled part 13 is the most fragile of all so that only this part extends, with preventing the other parts from being extended. The first knurled part 12 is thus prevented from losing the positioning function caused by its extension and contraction and eliminated from not being reused. The second knurled part 13 especially can be manufactured by rolling as well as the first knurled part 12 so as to dispense with a separate process as in the past and reduce the manufacturing cost.
