IPC: H03J7/28
Filed: 1980-01-31
Abstract: PURPOSE:To enable automatic channel selection with the output signal of a delay circuit, by providing the delay circuit which gives a delay for a given time to the output signal of a comparator, and controlling the generation of automatic stop signal with the output signal of a circuit 20. CONSTITUTION:The output signal of an IF filter 5 is fed to the input side of a buffer amplifier 10, and the output of the amplifier 10 is detected at 17 and fed to one input terminal of a comparator 18. The reference voltage VS of a reference power supply 19 is given to another input terminal of the comparator 18. Further, the signal obtained at the output of the comparator 18 is fed to one input terminal of an AND circuit 14 via a variable delay circuit 20. In this case, the delay time of the circuit 20 is varied from the time when the signal level fed from the output of the circuit 17 to one input terminal of the comparator 18 is greater than the voltage VS to the time when the reception frequency is sequentially changed and the signal level is maximum. The output signal of the circuit 20 controls the production of the automatic stop signal. Thus, automatic channel selection can be made at an accurate tuning point.

Title: Immunoassay of cell protein
Inventor: JIEIMUZU II BURAUN
IPC: G01N33/68
Filed: 1990-01-22
Abstract: PURPOSE: To perform immunoassay on a cell protein existing in a product refined from a mammalian cell culture medium as an impurity by more selectively adsorbing an antiserum to the cell protein than the medium protein. CONSTITUTION: A cell protein is separated from a medium protein and the antiserum to the separated cell protein is prepared. Then an antiserum from which the antibody to the medium protein is removed is prepared from the antiserum. The cell protein is determined by making the antiserum from which the antibody is removed to react to the well known diluting agent of the cell protein. The removal of the antibody is performed by passing the antiserum on a medium composition immobilized on a substrate. The determination of the cell protein includes the deciding step of the concentration of a specific antigen in the cell protein. The specific antigen is a cell fibronetin. The above- mentioned reaction can be caused with an ELISA(enzyme-linked immunosorbent assay) system.

CONSTITUTION:Urine is put into a sample tank 19. The entry of the urine is detected with a floating value detection sensor 23 from a change in level of a float 21 and an amount of the urine is detected with a urine quantity detection sensor 22. Signals from both the sensors 22 and 23 are inputted into a computer and the amount and a specific weight of the urine are computed and stored to be displayed on display lamps 12 and 13. After the measurement, discharge valves 34 and 38 are opened and a discharge pump 35 is driven to discharge the urine in the sample tank 19 and a measuring cylinder 20 from a discharge pipe 37. At the same time, a part of the urine is stored into a zone chamber 17a assigned of a sampling container 17 through a branch path having a pump 39 for dispensing and a valve 40 for dispensing. The valve 40 is controlled so as to be opened by a time corresponding to the amount of the urine stored in the sample tank 19. The urine thus stored can be utilized properly for other measurements thereby eliminating the need for resampling of the urine.

Title: Manufacture of semiconductor device
Inventor: YOSHIDA SATORU
IPC: H01L21/306
Filed: 1981-01-28
Abstract: PURPOSE:To ease the inclination of the opening section of a low temperature CVD oxide film, and to adjust the angle by forming the oxide film containing no phosphorus on a thermally oxidized film shaped to a Si substrate and forming an opening reaching the substrate through chemical etching. CONSTITUTION:In a window opening process of the thermally oxidized film 3 in an IC, etc., the SiO2 film 2 through a chemical reaction of SiH4 is deposited and shaped onto the thermally oxidized film 3 at a low temperature (300- 600 deg.C). A resist mask 1 is formed, the films 2, 3 are etched up to the substrate 4 by a fluoric acid group etching liquid, and the opening is shaped. Since the speed of etching of the CVD film 2 is faster than the thermally oxidized film 3, the etching advances as shown in dotted lines, and the side wall section of the opening takes the shape of a gentle inclination. The angle of the inclination can be adjusted by changing the thickness of the CVD film (when the thickness is increased, the angle is eased). Accordingly, the disconnection, etc. of an electrode and wiring in the stage difference section of the oxide film can be prevented.

Abstract: PURPOSE: To eliminate breakdown and life deterioration of the device and prevent variation in the distance between semiconductor laser and light collecting lens by detecting the temperature of the holder of a light collecting lens and maintaining the temperature of the holder constant by cooling or heating it.  
     CONSTITUTION: Temperature sensor 31 is buried in holder 26. By this sensor 31, the temperature variation of holder 26 is taken out as voltage in temperature detector 32. The difference between this voltage and reference voltage V 0  is taken out by differential amplifier 33, and it is made into a control signal. Filter 34 operates phase compensation on this control signal. Then, it is inputted to drive circuit 35, and thereby electronic heater-cooler 27 is operated so as to control the temperature. In this way, the temperature of holder 26 is maintained constant. As a result, since holder 26 has a constant temperature, the temperature of semiconductor laser 16 can be maintained constant, and the distance between laser 16 and light collecting lens 19 can be maintained constant.
