Title: Correcting system for reading output
Inventor: SASAKI HIROSHI
IPC: H04N1/028
Filed: 1979-09-29
Abstract: PURPOSE: To increase the accuracy of the reading reproduction action, by converting the white level signal of the background plate into the reciprocal value to then multiply it by the original reading signal and thus securing the averaging for the output signal although it may be positioned at the center and the both ends of the sensor in order to obtain a uniform picture signal.  
     CONSTITUTION: The signal D delivered from the controller 16 is set at a high level before the original is set at the reading part, and the 1st switch S 1  provided at the input end of the signal A is closed. After this, the 2nd switch S 2  provided between the memory 13 and the D/A converter 14 is closed along with the 3rd switch S 3  which supplies the picture signal B to the multiplier 15. Then the picture element mean value signal A of the sensor output of the white level obtained by scanning the background plate is applied to the reciprocal converter 12 via the A/D converter 11. Thus the reciprocal of the white level of the background plate is obtained by the converter 12 to be stored in the memory 13. Then the signal D is set at a low level, and each of the switches S 1 , S 2  and S 3  is switched to set the original. And the signal B is supplied to the multiplier 15, and the reciprocal value of the white level stored in the memory 13 is read out to carry out a multiplication. Thus the corrected output signal E is delivered.

Title: Gas concentration detecting element
Inventor: TSURUTA KUNIHIRO
IPC: G01N27/27
Filed: 1990-05-17
Abstract: PURPOSE:To facilitate the simultaneous measurement of an oxygen concn., the absolute humidity quantity and a combustible gas concn. by forming two pieces each of a pair of electrode films of an oxygen sensor, supplying the voltage above the electrolysis voltage of water to the one electrode film and supplying the voltage below the electrolysis voltage of water to the other. CONSTITUTION:The oxygen in the air is made into oxygen molecules by the transfer and receipt of electrons to and from the electrode 2a for supplying the driving voltage. The oxygen molecules release the electrons in the same electrode film 2b after the passage through a solid electrolyte plate 3 having an oxygen ion conductivity. These electrons flow out again as oxygen. The current exhibits a specified value regardless of the voltage value if the inflow of the oxygen is limited by a spacer 4 for controlling the oxygen diffusion. The oxygen concn. is measured by utilizing the characteristics of the threshold current. On the other hand, the threshold current by the spacer 4 is the current value added with the oxygen concn. and the moisture concn. and, therefore, the moisture concn. is measured by subtracting the current value obtd. from the electrode values 2a, 2b. The combustible gas comes into contact with a gas sensitive film 7 of a metal oxide semiconductor type. A change in the electric conductivity is detected by electrodes 6a, 6b for detecting the electric conductivity. The measurement of the concn. is thus executed.

Filed: 1978-10-16
Abstract: PURPOSE:To make reproducing high-efficient by specifying the thickness of plate- form materials and the interval of them in respect to the recording and reproducing head formed by arranging two magnetic plate-form materials in both sides of a reproducing element. CONSTITUTION:In respect to the vertical magnetization recording main head for recording as well as reproducing which is formed by arranging ferromagnetic films (Permalloy, ferrite, etc.,) 7 and 8 in both sides of reproducing element (spiral wire, Hall element, etc.,) 9 and subjecting them to mold 60, high-efficience reproducing is obtained by giving a fixed relation between the breaking wave length dependent upon the head interval and the breaking wave length dependent upon the thickness of head chip magnetic film. That is, though recording and reproducing have the approximately equal frequency characteristic if thickness l of the magnetic film and magnetic gap lg are set to satisfy the expression, the value of l is determined by the limit wave length at a recording time and is set to a value several times as large as lg for the purpose of avoiding saturation of the magnetic film for large signals. Then, it is desirable that inclination 55 is provided in the side opposite to the magnetic gap for the purpose of reproducing output drop at a high frequency.

Title: Sheet material conveying device
Inventor: YAMAGUCHI SEIHEI
IPC: B65H3/56
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To positively prevent double feed of sheet material stocked in a laminated state by arranging one of a pair of holding bodies with a passing part formed in the middle, in the state of spring force obliquely backward in a feed direction being imparted thereto. SOLUTION: When a plurality of postcards A in the overlapped state are about to enter a passing part 33, since a feed impeding roller 32a of an upper holding body 32 has backward and obliquely downward spring force imparted by a coil spring, the feed impeding roller 32a comes in backward and obliquely downward pressure contact with the upper postcard A. This pressure contact force P1 is decomposed into force P in the thickness direction (adhering direction) of the postcard A and force P2 in a feed impeding direction, so that feed impeding force can be increased while reducing adhering direction compared to the case of pressure contact force acting only in the thickness direction of the postcard A, which results in increasing the resolution of the postcard A.  Overlap feed caused by the adhesion of the postcards A can thereby be prevented, and the postcards A can be conveyed while being positvely separated sheet by sheet.
