Title: Conveyance detecting circuit of paper
Inventor: IKEDA EIJI
IPC: B65H7/12
Filed: 1989-11-14
Abstract: PURPOSE:To judge the transmitted light amount of paper accurately by composing the system to light a luminous light source intermittently, and correcting the quantity of light, detected by a light receiving element when the light source is lighted, with the quantity of light detected by the light receiving element when the light source is put out. CONSTITUTION:When the thickness of paper is judged by a CPU, the thickness of the paper can be judged by comparing the value of a registor 11 or 12 and a standard value stored beforehand in the CPU, in a device in which the quantity of receiving light receives no influence of the external irregular light. However, when the quantity of receiving light receives the influence of the external irregular light, a correct detection is carried out by removing the external irregular light. Therefore, the light receiving amount when a current is not fed to a luminous element 6 is stored in a registor 13, and it is transferred to the CPU to correct the value of the registor 11 or 12. In such a way, the thickness of paper is judged correctly, and two sheets conveying and the like can be detected.

Filed: 1989-11-13
Abstract: PURPOSE:To surely satisfy the connection request by discriminating it as the occurrence of a fault to a MODEM when a call signal is detected over a prescribed time or over and replacing the MODEM with a standby MODEM. CONSTITUTION:A MODEM 111 receives a call automatically in response to the signal fed via a line 101 to apply modulation and demodulation of the signal and a standby MODEM 112 is connected to the line 101 and used when a fault takes place in the MODEM 111. A processing means 102 applies processing based on a data received and sent via the line 101 and a switching means 121 connects normally the MODEM 111 to the processing means 102 and the standby MODEM 112 is selected in response to the switching signal. A detection means 122 detects a call signal supplied via the line 101 and a discrimination means 123 judges that a fault takes place in the MODEM 111 when the call signal is detected over a prescribed time and generates a switching signal to supply it to the switching means 121. Thus, the communication disable due to a fault of the MODEM is prevented and the connection request of the line is surely satisfied.

Title: Moving image compressing/coding method
Inventor: FUJIWARA SHIRO
IPC: H04N19/134
Filed: 1993-11-25
Abstract: PURPOSE:To prevent the change of picture quality caused by factors other than the change of the image contents in moving image compressing/coding. CONSTITUTION:The input moving image data are converted by a DCT converting part 100 and written into a frame memory 14 and also inputted to an AC component adder 16 which calculates a high frequency component. A quantization control part 50 selects approximately optimum quantization characteristics based on the sum of the target code value and the AC component, and a quantizer 200 quantizes a DCT coefficient. This quantized coefficient is coded by a variable length coder 300, and this coding data is written in a buffer memory BM 40. Meanwhile the 2nd quantization characteristic decided by the difference between the code value of the coding data and the target code value is selected. Then the DCT coefficient undergoes again the quantization and the variable length coding and is stored in a BM 42. Then the coding data closer to the target code value is used as the compression data out of both coding data stored in the BM 40 and the BM 42 in regard of the frame images.

Title: Detecting device for deterioration degree of catalyst
Inventor: SAWADA YUTAKA
IPC: F02D41/14
Filed: 1991-11-12
Abstract: PURPOSE:To exactly detect the degree of deterioration of a catalyst by calculating the absolute quantity of oxygen adsorbed to the catalyst after switching of the air-fuel ratio based on the quantity of exhaust gas circulated through the catalyst by the time a detected air-fuel ratio has reached a desired air-fuel ratio, and the deviation of the desired air-fuel ratio from a theoretical air-fuel ratio. CONSTITUTION:A catalyst 11 is arranged in the exhaust system 10 of an internal combustion engine. Further, an air-fuel ratio sensor 18 is arranged at least downstream of the catalyst 11 in order to detect the air-fuel ratio of an air-fuel mixture supplied from a fuel injection valve 12, etc. In this case, the detected air-fuel ratio is switched to each scheduled air-fuel ratio on the rich side or on the lean side with respect to a theoretical air-fuel ratio by a means A. Besides, after the switching of the air-fuel ratio, the quantity of gas circulated through the catalyst by the time when each scheduled air-fuel ratio is reached, is detected by a means B. Then, the absolute quantity of oxygen adsorbed by the catalyst is calculated by a means C based on the deviation of each scheduled air-fuel ratio from the theoretical air-fuel ratio after the switching of the air-fuel ratio, and the quantity of gas circulated through the catalyst. Thus, the degree of deterioration of the catalyst is detected by a means D based on the absolute quantity of oxygen.

Title: Method for measuring refractive index of solution by optical fiber
Inventor: ISHIZUKI HIDEAKI
IPC: G01N21/43
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To measure the critical incidence angle and the refractive index for an optical fiber by peacing the optical fiber where a protection coat covering is partially or entirely stripped and measuring transmission intensity when light is applied to the optical fiber. SOLUTION: An optical fiber 1 is composed of a core 9 and a clad 10. In a general optical fiber, the outside of the clad 10 is subjected to protection covering, and laser beam from a light source enters at a low angle where it is not diffused greatly, so that nearly entire incident light is totally reflected by the boundary surface between the core 9 and the clad 10 and is transferred into the core 9. When the outside protection covering of the optical fiber is released and hence the outside of the clad 10 is brought into contact with liquid to be measured, incidence light from a dispersion light source becomes a beam being totally reflected by interface between the clad 10 and a measurement container 4 as in a beam A-A' when the angle of incidence becomes larger in addition to other beams being propagated in the core 9.

Title: Air preheater of separated heat pipe type
Inventor: MOCHIZUKI MASATAKA
IPC: F28D15/02
Filed: 1985-12-27
Abstract: PURPOSE:To completely discharge non-condensed gas by a simple structure, by constituting a loop structure between heat pipes by providing a connecting pipe for steam and the one for condensate between each end of the upper header of a cluster of evaporating pipes and the lower header of a cluster of condensing pipes respectively, and by providing a gas vent valve on the upper header of condenser pipes. CONSTITUTION:Air is flowing through an air flow path 24, and a liquid operating fluid remains at the bottom of a cluster of evaporating pipes 15, at first when high temperature waste gas is fed into a gas flow path 19. The fluid gradually evaporates, turning into steam by the heat of waste gas, going up to the cluster of condensing pipes 20 via an upper header 17 and a connecting pipe for steam 25. The steam is deprived of its heat by the air flowing through the flow path 24, being condensed and liquified. Then the condensed operating fluid drips down to the lower header 23 through the inside of condensing pipes 21 and returns to the cluster of evaporating pipes 15 via a connecting pipe for condensate 26. The operating fluid which is turned into steam radiates heat and is condensed and is liquified in the condensing pipes 21. During this time, non-condensed gas is produced in the sealed pipes, flowing from the side of a cluster of evaporating pipes 15 to the side of a cluster of condensing pipes 20. The non-condensed gas is gathered in the upper header 22 of a cluster of condensing pipes 20. The gas can be completely discharged by opening a gas vent valve 27 provided on the upper header 22 at regular intervals.
