Title: Distortion correction circuit for quantitizing figure
Inventor: MORI NOBUHIKO
IPC: G06V10/10
Filed: 1980-08-12
Abstract: PURPOSE:To correct the distortion of an input figure which receives regular distortion by storing the information of plural and continuous columns or rows in the information of a quantitizing figure in a shift register sequentially and reading out the contents of a bit position which has been previously selected corresponding to the distortion in the shift direction of the shift register. CONSTITUTION:A shift register 6 stores sequentially the quantitizing value of each point of an input figure sent from a scanning device 5 and, when the figure information for one row or one column is inputted to the shift register 6, the information is inputted to a shift register 7 with the same sample points as one column or one row. At the same time the contents of the register 7 is shifted to the right by one bit, the contents of the register 6 is written in the leftmost digit of the register 7 to store continuous figures with subscribed columns or rows in the register 7. A figure with distortion which is enclosed with a thick frame and has been previously selected is read out in the register 7 and, after correcting the distortion, the corrected figure is stored in a memory 8.

Title: Method for inspecting precisely defect of light transmitting pipe material
Inventor: TAKEUCHI SHINJIROU
IPC: G01N21/952
Filed: 1983-06-20
Abstract: PURPOSE:To detect automatically with high accuracy a minute defect by shaping light of an illuminating light source to a slit light band by a slit plate, and setting an irregular reflecting position in a defect as a position of a transmitting light side. CONSTITUTION:Irradiating light is made in parallel light, passes through a slit hole S2 and becomes a slit light band. In case a light transmitting pipe material 7 whose inside diameter is R and in which a defect F0 exists on its inside surface is irradiated by a light band whose center axis is L-L', when the defect is very minute irregularly reflected light also becomes very weak. Therefore, brightness of the reflected light is intensified by making an angle made by a transmitting light axis F0-F0'-L' and measured axes Bd, Ad as small as possible. With regard to a position where a production in the opposite direction of measured axes F0', Ad'' whose measured angle is theta'' crosses a slit plate 5, a light shielding limit level is made a level of a distance H0 which can be calculated by measuring from the lower face of a slit hole S2.

Title: D-a converter
Inventor: SUMI KATSUAKI
IPC: H03M1/74
Filed: 1989-04-28
Abstract: PURPOSE:To decrease the degree of high frequency noise included in a digital signal from being leaked to an analog signal output by connecting respectively a transistor(TR) of the same size as a TR with smaller size among TRs with different size being components of a current source in series between the current source and an emitter common connecting point of plural differential pair TRs. CONSTITUTION:NPN TRs Q10, Q20 having the same size as that of a TR Q3 are provided respectively between the emitter common connecting point of the TRs Q1,Q2 and the collector of the TR Q3 and between the emitter common connecting point of the TRs Q4, Q5 and the collector of the TR Q6. Since the size of the TRs Q10, Q20 is the same as that of the TR Q3, the side area and the bottom area of an n<-> epitaxial layer 32 are far smaller than those of the TR Q6. Thus, the stray capacitor C2 caused in the collector of the TR Q20 is remarkably reduced more than that of the TR Q6. As a result, the degree of noise leaked to the analog signal outputted to an output terminal 8 is reduced.
