Title: Enzyme immunity examining method
Inventor: NAITO KAORU
IPC: G01N33/543
Filed: 1994-03-29
Abstract: PURPOSE:To detect whether a limiting enzyme exists or not and, if exists, its quantity, and consequently to detect whether an aiming substance exists or not and, if exists, its quantity by using the limiting enzyme as a label of an antibody or an antigen which reacts with the aiming substance and adding the antibody or the antigen labelled by the limiting enzyme as a detection reagent to an object sample. CONSTITUTION:An antibody or an antigen is labelled with a limiting enzyme to give a detection reagent and the reagent is reacted with an object sample. If the antibody or the antigen exist in the object sample, the reagent is bonded with an aiming substance with extremely high specificity. An immunologically reacted compounded body is obtained by removing not reacted detection reagent by B/F separation of the reaction system. At that time, the immunologically reacted compounded body contains extremely slight amount of the limiting enzyme. To detect the slight amount of the limiting enzyme, a DNA chain having base sequence which the enzyme cuts is added to carry out a reaction. Due to the reaction of the enzyme and the base sequence of the DNA chain to be cut, a large quantity of DNA chain fragments ate produced. These DNA chain fragments are located locally in specific positions by fractionizing them by electrophoresis and whether the aiming substance exists or not can be observed based on fluorescence and the quantity of the substance can be determined by measuring the intensity.

Title: Contact-making heater and contact-making equipment using the same
Inventor: NAGASEKO RYUICHI
IPC: H01L21/52
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To improve temperature distribution of a heater itself for evenly conveying heat to a portion subjected to heating even if the heating temperature rises, by burying a heating resistor in such a manner that the resistor encircles an suction hole, which is used to suck an object to be subjected to heating, of a ceramic heater. SOLUTION: A ceramic heater 2 consists of a square heating portion 4, a heating resistor 4a, a lead portion 6 which applies voltage to the heating resistor 4a, and an electrode lead 7 formed on the end of the lead portion 6, and is equipped with three suction holes 5 for sucking a semiconductor chip and a head 2. The wiring of a heating resistor 4a is buried in such a manner that it encircles an suction hole 5 so as to maintain the temperature around the suction hole 5. The distance (b) between the suction hole 5 and heating resistor 4a is desirably adjusted to 0.7 mm or less. As the heating temperature rises, the temperature of the electrode lead 7 also rises, which produces cracks, causing decrease in strength.  To solve the problem, the distance (a) between the square heating portion 4 and the electrode lead 7 is increased to 10 mm or longer so as to lower the temperature of the electrode takeout portion.

Title: Measuring instrument for shape of electron beam
Inventor: OSADA TOSHIHIKO
IPC: H01L21/027
Filed: 1978-05-18
Abstract: PURPOSE: To improve the measurement accuracy of the sectional shape of electron beam by absorbing the scattering secondary electrons produced as the electron beam hits against the end of a shield such as knife edge or the like with a metal plate.  
     CONSTITUTION: When in the scanning process of an electron beam 6 the electron beam 6 is radiated to the knife edge 1a of a shield 1, secondary electrons are produced from the knife edge 1 and scatter as shown by dotted lines. However, these scattering secondary electrons are lower in energy as compared to the electron beam 6, and therefore they are absorbed in a grounded metal plate 2 and do not arrive at a PIN diode 3. As a result, the voltage change point at the output end A of a current-voltage converting circuit 4 becomes distinct. Hence, the differentiating waveform of the output voltage waveform of the output end A becomes distinct square wave, permitting easy and accurate measurement of the width d. From this and the scanning speed of the electron beam 6, the width of the electron beam 6 may be measured.

Filed: 1983-04-05
Abstract: PURPOSE:To reduce the load on a main processor, and composing each device of a microprocessor and attain size reduction and simplification by receiving and analyzing a signal by a processor dedicated to reception, and processing only significant data by a main processor. CONSTITUTION:A common line signal controller 1 controls the transmission, reception, acquisition, etc., of a common line burst, and the processor 2 dedicated to reception reads and analyzes only receive data in a signal controlled by the controller 1 to judge whether the data is required for the station or not. The data required for the station is edited and written in a queue 4 and unnecessary data is discarded. Therefore, the processor 2 reads only a signal to its station, so a slow processor can handle data on a high-speed common line; and the main processor 3 performs processing at a speed slower than the burst period of the common line while unnecessary data is present on the common line, so the processors 2 and 3 are composed of microprocessors.

Title: Magnetic read checking circuit
Inventor: URANO ICHIRO
IPC: G11B5/09
Filed: 1986-03-17
Abstract: PURPOSE:To detect whether an abnormality exists or not, prior to a read operation for a magnetic data, by checking whether an output of a magnetic head has exceeded some threshold value or not, when the magnetic head is not reading the magnetic data of a medium. CONSTITUTION:An output signal 201 of a magnetic head 9 is rectified and amplified by a rectifying and amplifier circuit 102 and becomes a signal 202. The signal 202 is compared with a reference voltage 203 by a comparator circuit 103, and when the noise exceeds a voltage 203, an output 204 becomes '1'. On the other hand, a 2-input NOR circuit 105 outputs a signal 8 which becomes '1' only when a photodetecting part is not detecting a feed medium. A 3-input AND circuit 104 makes a signal 204 effective only when a roller rotating signal is '1', and also, the signal 208 is '1'. That is, only when the roller is rotating, and a read operation by the magnetic head is not being executed, the signal 204 is sent as an output signal 209 to a set input of an S-RFF 106. In this way, before the magnetic head executes a magnetic read operation for a magnetic data of the medium, it can be detected that an abnormality exists in a read system.

Through another contact of relay 36 not shown in the figure, a solenoid valve, etc., holds gas to the burner to continue the combustion by the burner and also to stop power feed to an igniter. Once the pilot burner goes off, thermoelectromotive force (e) of thermocouple 9 decreases and the signal from the amplifying circuit is converted by the proportional differentiating circuit into the output of the gradient of the fall of thermoelectromotive force (e) and variations of the output voltage Vs are detected comparator 31 to turn transistor 35 OFF, thereby closing a gas circuit.
