IPC: F03G1/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To utilize the accumulated energization force of a spring so as to generation of effective power, by arranging in the inside of an air cylinder, a spring body and a deformable piston to support the spring body, and driving this deformable piston by a power source such as an electric motor through a connecting rod. SOLUTION: An electric motor 9 is driven, and the rotational force of the electric motor 9 is transmitted to a pulley 9 integrated with a crankshaft 6 through a belt 10 and the like. At this time, when a crank 5 on the crankshaft 6 reaches a top dead center, a spring body 2 is in a condition that, it is compressed to a maximum extent, and energy compressed is changed to bounce so as to be explosively released at the same time when the crank 5 is passed through the top dead center, so that the crank 5 is pushed down to a bottom dead center. Then, the energy of the spring body 2 is made to be zero, however, the crank 5 is further rotated and lifted by the inertia force of a flywheel 7 accompanied by the rotational speed of the crankshaft 6, and the spring body 2 is compressed again.  Then, when the inertia force of the flywheel 7 is made to be zero, the spring body 2 is compressed again by the electric motor 9, and after that, this action is repeated so as to continue power generation.

Title: Circuit and method for peripheral length calculation for connected area
Inventor: OTA YOSHIYUKI
IPC: G06T7/60
Filed: 1988-08-16
Abstract: PURPOSE:To calculate the peripheral length of each connected area at a high speed by calculating the number of pieces of boundary points existing between an area and a background at every labeled area and calculating the number of pieces of boundary points in every connected area, based on the number of pieces and the connecting relation. CONSTITUTION:By a temporary labeling part 1, labeling is executed by allowing prescribed density to correspond to a picture element in an area in order to discriminate each of plural areas scattered in an image. An inter-label connecting relation detecting part 2 detects a connecting relation of each temporary label area, based on information related to whether each picture element to which a temporary level is given is connected or not. By keeping pace therewith, a boundary point calculating part 4 calculates the number of pieces of boundary points of the area and a background in picture elements of each area which is labeled temporarily by the labeling part 1 and holds it until the detection of the connecting relation is ended. Subsequently, when the detected connecting relation is sent out, the calculating part 4 calculates the number of pieces of boundary points at every connected area, based on the number of pieces of boundary points of each area and its connecting relation, and calculates the peripheral length of each connected area.

Title: Surface switch control system for received data memory
Inventor: NISHIDA MITSUHIRO
IPC: H04L69/40
Filed: 1989-08-04
Abstract: PURPOSE:To reduce the load of the software of a processor by performing the surface switch control of a data memory set at the reception side in terms of hardware with use of an error check code. CONSTITUTION:A transmission processor 31 is provided with an error check code generating circuit 33 which produces an error check code from the communication data. This produced check code is added to the communication data and sent to a reception processor and received by an error check circuit 44. The circuit 44 checks the errors with use of the received error check code. When the occurrence of an error is detected, the surface switching operation of a received data memory 42 is stopped. Thus the communication data having an error is never read out to a processor 43. As a result, the processor 43 always reads the correct communication. Then the load of the software of the processor 43 can be reduced.

Title: Wet electrophotographic developing device
Inventor: OISHI CHIKASHI
IPC: G03G15/10
Filed: 1992-07-07
Abstract: PURPOSE:To prevent developer from reversely flowing on the upstream side of a developer discharging part and to prevent developing irregularity and stain at a non- image part caused by reversely flowing developer from occurring by making the top end of a blade contact with or close to the surface of a photosensitive body. CONSTITUTION:A photosensitive body 11 makes an aluminum supporting layer on a lower surface grounded through grounding terminals 17 and 18, and gets in the entrance of a developing gap by getting under the lower end of 'Teflon(R)' blade 20. The developer is discharged from the discharging port 5 of a developer supplying unit 6, and flows in the developing gap along the one side of the blade 20; however, since the flow of the developer acts to press the top end of the blade 20 against the photosensitive body 11, the developer is prevented from reversely flowing from the lower side of the blade. Thus, the photosensitive body 11 is developed under a developing electrode 4 biased by a bias power source 13 to a specified voltage, and passes through a squeezing roller 9 to be carried while passing through the developing gap. The electrical insulating ability of the 'Teflon(R)' blade is high and coefficient of friction is small so that latent image charge on a surface is not disturbed by the contact with the photosensitive body 11.

Title: Data carrier
Inventor: ISHII HIDEKAZU
IPC: G01S13/82
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To suppress the rise of a voltage more than needed when the distance between a base unit and a hand set is comparatively shortened. SOLUTION: Signals from the base unit are received by a tuner circuit composed of an antenna coil 1 and tuning capacitors 2 and 3. While parallelly connecting the tuning capacitor 3 and a variable capacity diode 5, further, the tuning capacitor 2 is serially connected. In order to obtain power to be used in a data carrier, a voltage is rectified by a diode 4. The rectified voltage is detected by a resistor 6 and applied to the variable capacity diode 5. When the distance between the data carrier and the base unit changes and the rectified voltage rises, the capacity of the variable capacity diode 5 changes, the tuning frequency of the tuner circuit is gradually deviated from the frequency of signals from the base unit, and an induced voltage is reduced.

IPC: G09G3/20
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To ease or eliminate an effect of drive dispersion and to improve display quality by increasing a drive margin. SOLUTION: After a strobe pulse 3 for making an element an optional display state in a selection period is applied to a scan electrode of a ferroelectric liquid crystal display element, a TRIFLE(technique to reduce the long field latching effect) pulse 4 of the polarity opposite to the strobe pulse 3 is applied to the scan electrode, and a pause period (d) during which a scan voltage becomes 0 is provided between the applied period of the strobe pulse 3 and the applied period of the TRIFLE pulse 4. Thus, when the TRIFLE pulse 4 is applied to the scan electrode, the switching to a dark state is stabilized than the case that the pause period d is not provided, and the original effect of the TRIFLE pulse 4 is strengthened, and a non-rewrite margin is increased.  Thus, the final drive margin being a common part between the non-rewrite margin and a rewrite margin is also increased necessarily.

Title: Magnetic resonance video method and device and gradient high frequency magnetic field generating coil
Inventor: OKAMOTO KAZUYA
IPC: G01R33/48
Filed: 1988-08-16
Abstract: PURPOSE:To reduce the distortion of a chemical shift spectrum due to a frequency offset with a chemical shift by impressing the 180 deg. pulse of a uniform high frequency magnetic field in the impression period of a gradient high frequency magnetic field. CONSTITUTION:For gradient high frequency magnetic field generating coils 4a-4c, the directions of magnetic fields are orthogonal to the directions of static magnetic fields, and simultaneously, the gradient high frequency magnetic fields having spacely primary gradients in the interest area of an object 1 are generated. A uniform high frequency magnetic field generating coil 5 generates the high frequency magnetic field in which an intensity is spacely uniform in the interest area of the object 1. Here, the impression period of the gradient high frequency magnetic fields is divided into two, and meanswhile, the 180 deg. pulse as the uniform high frequency magnetic field is impressed. The rotation of a magnetization with the synthetic magnetic field of the gradient high frequency magnetic field and the frequency offset by the chemical shift is corrected, and an encoding error at the time of encoding the phase of a magnetic resonance signal in a space position is reduced. Thus, the distortion of the chemical shift spectrum due to the encoding error is made small.

Title: Method and apparatus for electric spray isolation, mass analysis method and fire-detecting apparatus
Inventor: JOHN BENNETT FENN
IPC: G01N27/62
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To solve many problems brought about in an ESI(electric spray ionization) for a liquid of a high flow rate, a surface tension and a conductivity, by utilizing an automatic balance characteristic of a flow passing a core and driven by a capillary phenomenon. SOLUTION: A primary flow of a sample liquid enters from an arm part 11 of a T tube 12 and wets one end of a core 14. The core 14 extends from the interior of the T tube 12 by a required length through a plug seal 15 at an end part. The plug seal 15 prevents convection of the sample liquid, bringing about a capillary-driven flow of the sample liquid towards a leading end of the core 14. A leading end of the plug seal is present in the vicinity of an entrance of a capillary which passes a gas including ions from a spray chamber to a vacuum system where a mass analyzer is set. When a suitable potential difference is applied between the core 14 and entrance of the capillary, the sample liquid forms a tailor cone 17 at the leading end of the core 14.  A peak of a mass spectrum obtained from the sample liquid sprayed from the core with a low flow rate is higher than when the same solution is sprayed from a conventional jet needle with a higher flow rate.

Title: Phase jitter canceller
Inventor: AOTANI YOSHIHISA
IPC: H03H17/00
Filed: 1988-08-18
Abstract: PURPOSE:To make a phase jitter canceller stable by varying the value of a correction coefficient of a tap of an FIR adaptive filter in response to a distance of a reception symbol from the origin. CONSTITUTION:The size of an input symbol is calculated by a square device 301, a threshold level given by a comparator 302 is compared with an output ¦AK¦<2> of the square device 301 and a signal representing two cases, the output ¦AK¦<2> is larger than the threshold level and smaller than the threshold level, is outputted. Then a selector 303 selects one of two kinds of correction coefficients by using the signal, and a correction coefficient alpha1 is outputted when the value ¦AK¦<2> is larger than a threshold level and a correction coefficient alpha2 is outputted when the value ¦AK¦<2> is smaller than the threshold level. Since much noise component is included in the output of a phase detector 103 when the value ¦AK¦<2> is smaller than a threshold level, the coefficient alpha1 is made small so as not to correct the tap gain of the FIR adaptive filter 105 largely, and when the value ¦AK¦<2> is larger than the threshold level conversely, the coefficient alpha2 is made large so as not to correct the tap gain of the FIR adaptive filter 105 largely. Thus, a stable phase jitter canceller is realized.
