Title: Optical semiconductor element module
Inventor: SUZUKI AKINOBU
IPC: G02B6/42
Filed: 1995-03-28
Abstract: PURPOSE: To decrease near-end crosstalks without depending on the prescribed position after the optical axis adjustment of optical fibers by diagonally polishing the respective front ends of the optical fibers fixed and held in ferrules exclusive of a part of the end faces on a light receiving element side. CONSTITUTION: The respective front ends of the optical fibers 5 fixed and held in the ferrules 7 are diagonally polished exclusive of a part of the end faces 16 on the light receiving element 3 side. The output light of a light emitting element 2 is condensed by a first lens 10 and is coupled through an optical separating filter 9 to the optical fibers 5. A part of the output light reflected by the end faces of the optical fibers 5 is reflected as a stray light component in the forward direction of the front ends of the ferrules 7 by the optical separating filter 9.  There is no interference at the front end of the ferrules 7 and the entire part of the light is absorbed by repetition of reflection and dispersion by the inside walls, etc., of a module case while the density is lowered and, therefore, the light is no longer coupled as the stray light component to the light receiving element 3. As a result, the near-end crosstalks are decreased.

IPC: G06Q50/22
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To shorten the measuring time for removing an electrocardiogram waveform from an electroencephalogram waveform by detecting the appearing time point of the featured waveform of a pulse wave corresponding to the featured waveform of the electrocardiogram waveform, thereby facilitating the segment division of the electroencephalogram waveform for obtaining the estimated waveform of the electrocardiogram waveform. SOLUTION: An amplifier 3 amplifies the potential difference between an active electrode 1a and a reference electrode 1b and the potential of pulse wave sensors 2a and 2b and an analog/digital converter(A/D) converts it into digital signals to store in a storage part 5. A pulse wave extreme detecting part 6 directly detects the extreme of the pulse wave waveform with periodicity and the time point of appearing the extreme from the display picture of the pulse wave waveform.  An electroencephalogram dividing start point setting part 7 sets the start point of the division of the electroencephalogram waveform, a noise contamination estimating part 8 successively adds segments obtained by dividing the electroencephalogram waveform to obtain an average to obtain an estimated waveform, and an electroencephalogram signal extracting part 9 subtracts the estimated waveform from the electroencephalogram waveform to extract an electroencephalogram signal removed or the contamination of noise.

Title: Chemical luminescent cell
Inventor: TAKEUCHI HIROSHI
IPC: G01N21/76
Filed: 1986-03-28
Abstract: PURPOSE:To improve light emission efficiency by introducing a liquid mixture composed of a sample and reagent into the central part of a cell and extending the stagnation time of the sample and the reagent in the cell. CONSTITUTION:The sample soln. and luminescent reagent soln. introduced from an introducing port 4 into the cell are mixed to react with each other. The liquid mixture flows as a luminescent liquid in a liquid flow passage formed of partly notched partition walls 2-1-2-3 toward the peripheral part and thereafter, the liquid mixture is led to the outside of the cell from a leading-out port 5. The emitted light from the luminescent liquid is transmitted through a transparent window plate 10 and the emission intensity thereof is detected by a photodetector. The notched parts are so positioned that the distance between the notched parts of the partition walls 2-1-2-3 contiguous to each other is longest as shown in the figure (b). The mixing of the freshly entering soln. and the soln. with which the reaction is already effected is, therefore, prevented. The cell is so constructed as to introduce the liquid mixture composed of the sample and the reagent into the central part of the cell and the strong emitted light in the initial period of the reaction is received in the central part of the photodetector by such construction, and therefore the emission efficiency of the chemical luminescent cell is remarkably improved.

Title: Integrated circuit device
Inventor: KANAYAMA HIDEYO
IPC: G06F1/04
Filed: 1985-04-03
Abstract: PURPOSE:To set the titled device into the standby state by both an external signal and an internal signal by providing an operation control means of an oscillation circuit, a control means stopping and restarting the operation of the oscillation circuit and an operation control means for a counter and a timing generation circuit to an LSI including the oscillation circuit and the timing generation circuit. CONSTITUTION:When the external signal 33 goes to a logical 1, an F/F 30 is set, an output of an OR gate 34 goes to 1 and the oscillation circuit 10 and the timing signal generating circuit 20 are stopped. Further, a counter 70 is reset and brought into the standby state. When the signal 33 goes to logical '0', the circuit 10 and the counter 70 are brought into the operating state. The F/F 60 keeps the set state until an overflow signal of the counter 70 is outputted and the circuit 20 is in the stop state. When the operation of the circuit 10 is restarted, an overflow signal is generated from the counter 70 by using a signal 11 after the time required for oscillation stability elapses. Thus, the F/F 60 is reset and the circuit 20 starts also the operation. When a standby internal signal 42 is outputted, an F/F 40 is set to form the standby state. When a standby release signal 51 goes to logical 1, the F/F 40 is reset.

Title: Formation of color filter substrate
Inventor: TANAKA TAKAOMI
IPC: G02F1/1335
Filed: 1995-03-29
Abstract: PURPOSE: To make it possible to easily correct the surface projection defects generated in a color filter substrate without affecting the circumference by correcting the substrate projection defects of the respective layers of the color filter substrate consisting of the color filter layers and transparent conductive layers with a high-pressure liquid, such as water. CONSTITUTION: The color filter substrate subjected to marking at the previously checked projection points is fixed onto a stage 10. An operator adjusts the opposite position of the marked projection point of the color filter substrate and a high-pressure nozzle 14 by operating a control panel 11 while checking the position with a television monitor 12. While the pure water is thereafter showered to the color filter substrate from a shower 17, the high-pressure water is injected from the high-pressure nozzle 14 to chip away the projection defect on the substrate surface. There is no heating stage and in addition, the color filter layer and the water maintain contact with each other at all times during the correction according to this method and, therefore, the change in properties and deformation by heat generation are prevented.

Title: Self-suction type pump
Inventor: TAMURA KOUZOU
IPC: F04D9/02
Filed: 1978-06-14
Abstract: PURPOSE: To reduce the size of the pump by returning to an air-water separating chamber a part of the water overflowed from the air-water separating chamber at the time the water level in the air-water separating chamber is about to fall and thereby preventing the drop in the self-suction action.  
     CONSTITUTION: A discharge gate is provided at the upper end of air-water separating chamber 15, and water is supplied outside via pipe joint 19 and discharge pipe 21. Expansion chamber 23 is formed in pipe joint 19. Air-water separating chamber 15 is linked to reserve chamber 11 by means of returning water port 25. At the time of the operation of the pump, by the pumping action of impeller 5 water is supplied from suction hose 7 to discharge pipe 21. But when the pump is not in operation, the return flow of water is prevented by stop valve 27 provided between suction port 9 and reserve chamber 11. Consequently, the water overflowed at the start of self suction is stored in the expansion chamber, and when the water level is about to fall, the stored water is returned to the air-water separating chamber. Thus, the inflow of air is reduced, and thereby, the capacity of air-water separating chamber 15 can be made small without obstructing the air-water separation.
