Title: Piezoelectric flow control valve
Inventor: WATABE YOSHIYUKI
IPC: H01L41/08
Filed: 1987-10-16
Abstract: PURPOSE:To obtain the large curvature displacement by setting the ratio of supporting length of a valve unit from its peripheral end in a radial direction to thickness of a disk-shaped piezoelectric element to a valve of 2 or less. CONSTITUTION:Gluing a disk-shaped piezoelectric element 1 to a metal disk 2 forming a valve unit, its one surface peripheral edge is supported by a rigid member further another surface peripheral edge is pressed and held by an elastic member 5. This valve unit sets the ratio l/t of supporting length l of the valve unit from its peripheral end toward the radial direction to thickness of the disk-shaped piezoelectric element to a value of 2 or less. By satisfying this condition, the stable curvature displacement enables its reproducibility to be realized while preventing the piezoelectric element valve unit 1 from excessively increasing its fixed moment.

Title: Production of highly pure polymer
Inventor: KONDO SHINICHI
IPC: C08F6/00
Filed: 1994-09-30
Abstract: PURPOSE: To produce a highly pure polymer useful for, e.g. a binder for a magnetic powder by removing impurities such as free salts, a surfactant and an unreacted monomer from a polymer latex by a specified process. CONSTITUTION: A highly pure polymer is produced by repeating concentration of a polymer latex obtained by emulsion or fine suspension polymerization with an ultrafiltration membrane and dilution of the concetrate with water. Examples of the polymers used include a vinyl chloride polymer, an acrylate polymer, a methacylate polymer and a styrene polymer. When the polymer is intended for use as a binder for a magnetic powder, it is desirable that the polymer is purified to such an extent that the electric conductivity of the polymer latex decreases to 800μS/cm or below when measured under conditions including a solid concentration of the latex of 40±2wt.% and a temperature of 30±2 deg.C. The operating temperature of the ultrafiltration is usually 25-40 deg.C.  It is desirable that the flow rate of the polymer latex during the ultrafiltration is 1-5m/sec in terms of linear velocity.

Title: Signal distribution method
Inventor: ASO TAKASHI
IPC: H04L69/40
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent stop of signal distribution in the case of a composite fault by retrieving a path for signal distribution from each path distributing a signal in the case of a fault in both active and standby signal distribution systems. SOLUTION: A primary rating means 53 receives monitor information of a system A distributing an active signal and a system B distributing a standby signal with outputs IN-0, IN-1 of OR circuits 51, 52. When the system A has no fault, no switching is made and when the system A is faulty and the system B has no fault, the system B is selected. Furthermore, when both the systems A, B have a fault and the switching by the primary rating means 63 is not made immediately, the secondary rating is set. In the secondary rating, a fault is detected from each path distributing a signal to retrieve a path able to distribute the signal and when a path able to distribute the signal is found out, the path is selected. Thus, when any signal distribution path is left, the supply of signal is not stopped.

Abstract: PURPOSE:To facilitate the adjustment of sensitivity, by comparing the output value of concentration when a gas to be sensed is detected with set operating value to discriminate the existence of abnormality. CONSTITUTION:When a desired sensitivity is set a with ten key 10, it is memorized into RAMs 1 and 11, then transferred to RAMs 2 and 12 and a pulse with the frequency corresponding to the sensitivity memorized is sent to a micropump 5 through a pump controller 7. Each time receiving a pulse, the pump 5 emits a fixed amount of sample gas supplied from a sample container 6 through a pipe 3 so that the gas concentration in a detecting chamber 4 will correspond to a set sensitivity. The current output value of a gas sensor element 1 each is sent to a CPU 8 by an A/D converter 9 and memorized into RAMs 3 and 13 as said operating value. Now, when the sensing chamber 4 is opened, the gas being sensed advances and the gas concentration detected with the element 1 and sent to the CPU 8 through the converter 9 to be compared with set values memorized in the RAMs 3 and 13. When the output value of concentration of the gas being sensed is larger than a set value, abnormality is alarmed by a display unit 15.

IPC: F25B47/02
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To suitably and effectively defrost respective evaporators by operating a fan for a cold storage until a sensing temperature of an evaporator temperature sensor for a cold storage arrives at a predetermined temperature in a refrigerating mode. SOLUTION: A controller 44 starts a refrigerating mode after a cold storage mode is finished, operates a fan 26 for a refrigerating chamber 18, and supplies the air cooled by an evaporator 24 for the chamber to the chamber 18. A fan 36 for the refrigerating chamber continues an operating state. That is, it conducts a delay operation to melt frost adhered to an evaporator 34 for a cold storage chamber 14 and heats in the chamber 14 and a vegetable chamber 16. If a sensing temperature of an evaporator temperature sensor 38 for a cold storage arrives at 1 deg.C, it is judged that the frost is completely removed, and stops operating of the fan 36. Thus, the fan 36 is operated until a temperature of the evaporator 34 arrives at a predetermined temperature, and hence adhered front can be effectively removed.

Besides a problem that the position of feed air holes 20 needs to be changed in accordance with the thickness of a wall (W) to fit the air duct 15 can be solved by adjusting the length of a feed air hood 17 in accordance with the thickness of the wall.

Filed: 1988-10-18
Abstract: PURPOSE:To recognize an object even when it is brought into contact with or overlapped on another object by judging matching by the prescribed attributes of the pair of line segments of the object targeted to be recognized and that of the unknown object. CONSTITUTION:A contour tracing part 1 converts inputted image data to the chain code of Freeman, and processes the chain code by a line segment approximation part 2, and approximates the contour of the object targeted to be recognized by the line segment. A line segment generating part 3 forms, for example, the pair of line segments by two continuous objects, and the data of the line segments and the attributes of the object targeted to be recognized and the unknown object, etc., are stored in a recognition targeted object line segment pair storage part 4 and an unknown object line segment pair storage part 5. And the matching is judged from, for example, the difference of length of the line segments or the error of the positions of the unknown object and the object targeted to be recognized by a matching pair recognition part 9, and it is judged that the matching is taken finally for the objects when the difference is less than a prescribed value. Therefore, it is possible to recognize the object even when it is brought into contact with or overlapped on another object.

Title: Solid-state image sensing device
Inventor: TAKADA MASAYA
IPC: H04N5/335
Filed: 1987-10-16
Abstract: PURPOSE:To facilitate the reduction of split noise by a method wherein a concentration gradient is produced in a reset MOS transistor channel region. CONSTITUTION:In this design, a concentration gradient is created in a channel region 10 just under a reset gate electrode 7 of a reset MOS transistor. In such a design wherein concentration is allowed to change beginning at a charge detection region 5, in the order N<++>-N<+>-N, potential is lower toward the left. This allows almost all charges in the reset MOS transistor channel region 10 to flow into the charge detection region 5. When the signal outputted by a source-follower circuit 100 is corrected for a quantity equivalent to the charge in the channel region 10, split noise may be reduced.
