IPC: G06K9/00
Filed: 1977-11-19
Abstract: PURPOSE:To make it possible to perform a two-dimensional blur operation with a superior reproducibility by applying the output of a temporary memory circuit to a digital filter to obtain the average of the output of the temporary memory circuit and stopping second-direction high-frequency components scattering in respect to time. CONSTITUTION:Picture signals have high-frequency components stopped through high-frequency stopping filter 27, and the output is converted by A/D converter 28 to subject picture signals to sampling, and the output is made into a digital picture signal. This signal is supplied to digital filter 29 to take out digital picture signals simultaneously at scanning points scattering in respect to time in the same position, and this taken-out output is supplied to temporary memory circuit 32 to accumulate temporarily digital picture signals at scanning points in the same position in the second direction of the first-direction scanning. Then, the output is applied to filter 29 to obtain the average of the output of the temporary accumulating circuit, and on a basis of this average, high-frequency components cencerning the second direction at scanning points scattering in respect to time are stopped, so that a two-dimensional blur operation with a superior reproducibility can be performed.

Filed: 1985-06-25
Abstract: PURPOSE:To detect the abnormality of an outer environment and to suppress the runaway of a control system by estimating the position of a controlled system properly on the basis of a controlled variable applied to the controlled system considering a model of a control system. CONSTITUTION:If the control system is normal, relation approximate to H(z)thetan= G(z)In can be formed between the position thetan of the controlled system which is a sampling value and the controlled variable In5. Provided that (n) is sampling time, G(z-1)=A1.Z<-1>+...+Ak.Z<-k> is the k-th mode of the control system and H(z-1)=1+B1.Z<-1>+...Bm.Z<-m> is the m-th model. When the position of the controlled system which is estimated from thetan2 and In5 is defined as Sn, (1+B1.Z<-1>+...+Bm.Z<-m>)Sn=(A1.Z<-1>+...+Ak.Z<-k>)In is formed, and when an error from the practically obtained thetan2 and an allowable error (e) are satisfied with ¦Sn-thetan¦<e, the control system is decided as normal. An error signal 14 is outputted to a selector 15 as '0' in case of the normal signal or '1' in case of abnormal. When the signal 14 is '1', the selector 15 switches the control variable 5 to 17 '0' to stop the controlled system.

IPC: B01D8/00
Filed: 1988-06-06
Abstract: PURPOSE:To recover Na with high efficiency from gas contg. Na vapor by cooling the gas by flowing fluidized inactive powder which has been contained at a desired temp. in a vessel into the gas, capturing condensed and separated Na with said inactive powder, and separating the inactive powder together with Na by centrifuging.

Title: Image input device and image input method
Inventor: ONODERA YUICHI
IPC: H04N1/19
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain a camera type image input device adopting an ambient light lightning system where flicker noise appearing as lateral stripes due to flickers or miscellaneous image appearing as lateral stripes due to excessive correction of flickers can be reduced even in the case of an original with a red color group in existence thereon. SOLUTION: A filter 12 is placed in an optical path through which reflected light passes from an original 114 to a linear image pickup element 101 via an image light collecting window 43, a mirror 107, and a lens 108 and a filter 11 is placed in an optical path through which part of light emitted from a light source (ambient light) passes to the linear image pickup element 101 via an environment light collecting window 44 and a prism 102. Filters transmitting relatively much reddish light having a small flicker noise level are adopted for the filters 11, 12.  The above problem can be solved by either or both of the filter 12 that passes through only an image signal with a frequency band having a small flicker noise level and the filter 11 that adjusts the division level at flicker correction to a frequency band having a small flicker noise level to avoid excess correction of the flicker noise in matching with the frequency band above.

Filed: 1980-10-03
Abstract: PURPOSE:To shorten a switching time, by constituting a circuit so that a comparator circuit for detecting connection or non-connection of a memory part, and a temperature characteristic of reference voltage of this circuit are made to correspond to a temperature characteristic of an input ''L'' signal, and also providing a circuit for clamping an input ''H'' signal. CONSTITUTION:The reference bias to be applied to a terminal 27b of a comparator circuit 27 for detecting connection or non-connection of a memory part of a fuse type bipolar PROM is almost equal to the ''L'' potential of an output signal of an internal output terminal 6, and its potential becomes high by decreasing or increasing values of resistances 28, 30 or a fuse 32. A DC noose margin is equal to the logical amplitude in an input of the circuit 27 which is required when an output terminal 5 is varied to the ''L'' potential from the ''H'' potential, by a difference between threshold voltage (=reference bias) of the circuit 27 and the ''L'' potential of an output of the terminal 6, and depends on the fuse 32, therefore, no temperature is changed. In case of the ''H'' potential of the terminal 6 at the time of a program, a clamping circuit 35 is turned on and off by a switch 36 in accordance with writing circuits 25, 37.

IPC: G01M3/38
Filed: 1988-06-08
Abstract: PURPOSE:To increase an inspection speed, to enhance inspection accuracy and to also detect leak quantity by providing a transparent fine pipe and a charge- coupled device. CONSTITUTION:Since the refractivity of the light passing across a transparent fine pipe 11 is different between the gas filled part and liquid filled part of the fine tube 11, the quantity of incident light to a charge-coupled device 16 in a light receiving part receiving the light emitted from a light emitting diode 14 is different between both parts. Therefore, by detecting a change in the incident quantity of light by the movement of the liquid level in the fine pipe 11, it can be detected that gas is newly introduced into the fine tube 11, that is, the gas is leaked from an object to be inspected. By using the device 16 as the light receiving part, the up-and-down stepwise change of the height of the liquid level in the fine pipe 11 can be detected and the height of the liquid level can be grasped analogously and, therefore, the stepwise change speed of the height of a liquid level can be converted to leak quantity.
