Title: Image plane detector for photographic film
Inventor: UEKUSA TADASHI
IPC: G03D15/00
Filed: 1990-03-16
Abstract: PURPOSE:To improve the accuracy of image plane detection by detecting the light passing a perforation forming part, extracting a base density signal, detecting the light passing an image part and comparing this signal with the above-mentioned density signal. CONSTITUTION:The light from a light source 12 transmitted through a negative film 11 is measured by a photodetecting sensor 20. A CPU 44 takes in the photometric data during the film feeding from photodetecting sensors 22A, 22G for perforation detection and extracts the smallest value in the data as the base density. The CPU 44 takes in the data from photodetecting sensors 22B to 22F for image plane detection and decides that the edge of the image plane passes the image plane detecting sensor 10 when the respective sensors change to the same value as the above-mentioned base density. The film 11 is fed at a fixed rate after the detection of the edge and the image plane 11B is set in the exposing window of a film carrier, then the film is subjected to print exposing.

Title: Oxygen concentration meter
Inventor: YASUDA SHIGEO
IPC: G01N27/00
Filed: 1991-03-29
Abstract: PURPOSE:To reduce occurrence of an error in an oxygen concentration signal by bringing an inlet and an outlet for gas to be measured into contact with each other and covering them with a heat insulating material. CONSTITUTION:Two auxiliary gas streams are combined into a stream of gas to be measured, while a magnetic field is applied to one of their joints to have the auxiliary gas flow rates varied by oxygen concentration of the gas to be measured to have the oxygen concentration detected. At this time an inlet pipe 22 and an outlet pipe 23 of the gas to be measured and an inlet pipe 24 of auxiliary gas are connected to a cell 21 in a thermostatic chamber 20 respectively. These pipes 22,23 are joined and brought into contact with each other by metal brazing 27, further formed in a spiral, and then covered by a heat insulating material 26 to have a heat exchanger 25 formed. Thus temperature of the gas to be measured flowing in the pipe 22 is made approximately equal to that of the pipe 23 at the temperature of the thermostatic chamber 20 in the heat exchanger 25 to be led into a cell 21. Therefore a flow speed sensor for measuring change in a flow rate of the auxiliary gas is stabilized and an error is not likely to occur in an oxygen concentration signal.

Title: Filler for affinity chromatography
Inventor: TAKEUCHI HIDEKI
IPC: G01N30/88
Filed: 1993-03-25
Abstract: PURPOSE:To obtain a filler having high refined purity and a large antibody absorbing capacity by using a carrier composed of a porous silica gel having a specific average pore size and carrying a ligand. CONSTITUTION:When a porous silica gel having an average pore size of 1,000-2,500Angstrom  is used as a carrier, albumins having a molecular weight of 67,000 can be easily washed away during a washing process and the refined purity of the silica gel can be increased to about >=90%, because the albumins can freely get in and out from the pares of the carrier. When the pore size is increased in such a way, the specific surface area of the porous silica gel carrier becomes smaller and, as a result, the amount of immobilized ligands and the antibody absorbing capacity of the carrier are reduced. However, when the pore size is increased, the immobilization rate of ligands is increased and the decrease in immobilized amount of ligands caused by the reduction in specific surface area can be sufficiently compensated. Protein A, protein G, protamine, etc., having a molecular weight of about 1,000-50,000 can be used as the ligand.

Abstract: PURPOSE:To make it possible to form a one-shot full color image and to make the device small-sized and to improve the copy speed, by using three color separating filters and three color photoconductive toners to perform development and exposure successively. CONSTITUTION:A photoconductive blue toner layer 15 charged with a polarity opposite to that of a bias power source 14 is formed on the surface of a developer carrying member 11, and the surface of a transparent conductive layer 16 connected to a bias power source 7 which has the same polarity as the power source and has a voltage higher than that of the power source 14 is brought close to or brought into contact with the toner layer 15 to expose the image of an original from the back of the conductive layer 16 through a red filter 19. The blue toner in parts corresponding to red and white parts of an original 18 is irradiated with a red light and becomes conductive and is repulsed by the conductive layer 16 to remain on the carrying member 11, and only the blue toner in parts corresponding to blue, green, and black parts of the original which are not irradiated with light is attached to the side of the conductive layer 16. Red and yellow toner images are formed by the same process, and thus, a color image consisting of photoconductive blue, red, and yellow toners is obtained on the conductive layer 16.

Filed: 1991-03-29
Abstract: PURPOSE:To prevent information collection from another normal terminal from being delayed even when a communication error occurs by deciding that a corresponding terminal is abnormal when the number of times of abnormality arrives at a prescribed number by a decision means as sending a prescribed signal from a managing signal sending means. CONSTITUTION:The CPU 11 of a centralized managing device sends a question character to the CPU 21 of a gate device 2n via interfaces 15, 25 and a wire 3. When no repsonse from the gate device 2n is obtained after the lapse of prescribed time, the CPU 11 judges it as the communication error, and counts up the number of times of error of an error state table 14c in accordance with the gate device 2n, and sends the question character to the CPU 21 of a gate device (2n+1). When the number of times of error of the table 14c in accordance with the gate device 2n arrives at the prescribed number of times, the CPU 11 informs the communication abnormality of the gate device 2n by using a CRT display device 13. Therefore, no delay of information collection from another normal gate device occurs even when the communication error occurs in the prescribed gate device 2n.

Title: Calling equipment
Inventor: OSADA MAMORU
IPC: H04M1/32
Filed: 1990-03-19
Abstract: PURPOSE:To secure a sufficient pausing time and to attain pulse/tone switching by setting a prescribed waiting time before starting the sending of a switched signal sequence when data for specifying the switching of the signal format of a selection signal is stored in an area other than the leading part of a storage area. CONSTITUTION:The 1st digit of a destination address is identified, and when pulse/tone switching is executed from the 1st digit, the residual digits of the destination address are immediately sent by tone signals, and when the pulse/ tone switching is executed from the digit other than the 1st one, a proper waiting time is automatically set up. Since it is unnecessary for a user to manually input pause data in each time as compared with a convensional method, the capacity of a memory 6 required for storing destination addresses can be reduced, and since the pausing time sufficient for allowing an opposite station to respond can be secured, the opposite station can surely be controlled.
