Title: Air bubble water flow generating apparatus
Inventor: OZAKI YUKINORI
IPC: A47K3/00
Filed: 1993-01-13
Abstract: PURPOSE:To make it possible to generate fine air bubbles and large air bubbles by means of a small-sized pump by feeding a high pressure water wherein air is dissolved by the action of an ejector with a variable suction pressure into the fine air bubble generating apparatus to generate fine air bubbles and feeding water ejected by the pump into a large air bubbles spouting means when large air bubbles are generated. CONSTITUTION:When air bubbles are generated, warm water ejected from a circulation pump 33 is made flow into a by-pass 43 side from a feeding pipe 36 and warm water in a return pipe 59 is sucked by sucking action of an ejector 42 through a sucking pipe 47 provided with a control means 46 for controlling sucking pressure. In addition, in this case, by opening an electromagnetic valve 51, air is sucked by the ejector 42 through a const. flow valve 50 and it is mixed with warm water. The warm water wherein air is thus dissolved is fed into a fine air bubble generating means 35 through a check valve 38 and fine air bubbles generated by rapidly decreased pressure are spouted into a bathtab 34. On the other hand, when large air bubbles are generated, the high pressure warm water is fed into a large air bubbles spouting means 41 through a two-way valve 39 and air is sucked from an air pipe 52 caused by a negative pressure to make it into large air bubbles, which are spouted into the bathtab 34.

Title: Estimate bit error rate measuring circuit
Inventor: FUJIMURA AKINORI
IPC: H04L1/00
Filed: 1991-01-17
Abstract: PURPOSE:To improve the reliability of an estimate bit error rate by detecting a specific bit pattern from a reception signal based on the quantity of the correlation with respect to a known signal. CONSTITUTION:A bit series of a demodulated signal is inputted one by one bit each to a correlation device with respect to each bit series in a soft decision correlation circuit 1, in which the correlation arithmetic operation is implemented between a synchronizing word in a received symbol and a synchronizing word in a same bit pattern. Calculation correlation values are all added after weighting and the result is compared with a threshold at a comparator 2. The calculated soft decision correlation is compared with thresholds for normal phase and inverted phase and the result is outputted to a selection circuit 4 as a a phase uncertain signal representing the pressure of inversion. An output detection signal and an aperture gate signal generated in an aperture gate generating circuit 6 are ANDed by an AND circuit 6. When undetection is caused, a psedo detection signal generating circuit 7 outputs a pseudo detection signal to an estimated position. When the synchronizing word is normal, the signal of the circuit 6 is synthesized by a selection circuit 8. Thus, the reliability is improved.

Title: Exhaust gas cleaner for internal combustion engine
Inventor: KUBOTA SHIYOUJI
IPC: F02D37/00
Filed: 1978-01-18
Abstract: PURPOSE: To improve exhaust gas cleaning effect by a spark delay operation regardless of the opening of a throttle valve while preventing deterioration in the engine power and drivability by stopping EGR operation when the temperature of the engine is low.  
     CONSTITUTION: When the rise in the temperature of the engine allows a switch 38 sensitive to the temperature of the exhaust gas to open, the excitation coil of solenoid cross valves 11, 17, 29 and 34 are demagnetized changing the opening-or-closing position the valves. Thus, an opening 15 is communicated to a negative pressure chamber A for spark advance through a pipe 13, a valve 11 and a pipe 10, an opening 20 is communicated to a negative pressure chamber R for spark delay through a pipe 18, a valve 17 and a pipe 16 and the passage for an opening 22 is closed. In addition, an opening 30 is communicated to a negative pressure chamber for an EGR valve through a pipe 28, a valve 29 and a pipe 26. Accordingly, the EGR valve 24 is allowed to properly open according to the value of the negative pressure in a suction pipe to perform the EGR operation. On the other hand, with the changeover of the valve 34, the supply of a negative pressure to a cylinder 32 of a power apparatus 31 is suspended. Accordingly, the cylinder 32 is opened to the atmosphere 35, whereby a pistion 41 is allowed to descend to push the button of a valve 42 open. Thus, a fuel 44 is fed through the valve 42 to perform concentration.

Filed: 1995-01-13
Abstract: PURPOSE: To suitable control the thread condition of a bobbin thread by preventing trouble from being generated such as the bobbin thread from getting entangled in a bobbin thread touch part by providing a control mechanism for controlling the position of a drawing port by moving a regulating member for regulating the rotation of a rotating hook bobbin case holder while being abutted to the rotating hook bobbin case holder. CONSTITUTION: The rotation of a rotating hook bobbin case holder 10 is regulated by a movable regulating member 22 at a control mechanism 33 and the position of a drawing port 18 is controlled so that the thread condition of the bobbin thread can be changed. Therefore, at the time of straight sewing, that position is controlled to the position of the drawing port 18 to provide the thread condition suitable for that sewing or at the time of zig-zag sewing, that position is controlled to the position of the drawing port 18 to provide the thread condition suitable for that sewing so that the thread condition of the bobbin thread can be controlled regardlessly of the sewing state.  Since the regulating member 22 is not arranged in the narrow space upside the rotating hook bobbin case holder 10 but can be parallelly arranged, its arrangement is facilitated, the lower thread does not touch any other member or the like, and trouble such as entangling the bobbin thread in the other member is not generated, either.
