Title: Driving method for reciprocating linear solenoid
Inventor: OZAWA HIDETAKA
IPC: H02P25/062
Filed: 1990-08-27
Abstract: PURPOSE:To make it possible to feed a predetermined exciting current with a lower voltage as compared with the case where the voltage is applied alternately by feeding alternating signals, having a phase difference, to solenoids for moving a plunger, respectively, in first direction and the opposite direction thereby reciprocating the plunger with half period of the alternating signal. CONSTITUTION:When alternating signals having different phase are applied on respective solenoids, a plunger is driven by the combined operating force of the solenoids and reciprocated with half period (double frequency of the alternating signal) of the alternating signal applied on the solenoids. Consequently, when alternating signals having phase difference of 0 or 180 deg. are applied on respective solenoids, operating forces of both solenoids are balanced to stop the plunger. If the phase difference is 90 deg. or 270 deg., current of one solenoid goes zero when the current of the other solenoid is at the maximum and a high operating force is produced. Consequently, when the phase difference is controlled without varying the amplitude of the alternating signal, operating force or stroke of plunger can be varied continuously from zero to a value corresponding to j 90 deg. or 270 deg. phase difference.

Title: Optical disc recoding/reproducing unit
Inventor: HAYASHI HIDEAKI
IPC: G11B7/0045
Filed: 1984-10-29
Abstract: PURPOSE:To detect a defect, etc. of a disc which recording and to take a countermeasure such as discontinuation or continuation of recording by applying intensity modulation to a light spot by an input data, and detecting a disc reflection detect signal in an irradiated section corresponding to a low intensity. CONSTITUTION:When input data I is reproduced in a recoding amplifier AMP, by applying a recording bias voltage VB to provide a laser power, a laser light is emitted in PD between the period where pits under recording are forming. Hence at the moment when a pick-up signal P is varied from H to L by the laser emission, the light spot is on a recording pit and reproduction is slowed down. By a voltage VR of the middle point where pit are not formed and the point where the signal varies from H to L, the signal P is waveform-sliced by a comparator COP to get a signal A. On the other hand the output of a circuit FF1 of the data 1 and the signal A are gated, and while the signal P is varied from H to L, the signal A is inverted to obtain a signal B. Then the clock CK is delayed in a delay circuit D, gated by an output of a circuit INV, and transferred to a circuit FF2 in an AND circuit, and the signal B is outputted OUT through a reading circuit INV2. By such an output OT, the defect of a disc can be detected while it is tested.

Abstract: PURPOSE:To separate a dissolving volatile substance efficiently by bringing a raw solution in which the volatile substance dissolves into contact with one side of a hydrophobic porous membrane having continuous fine pores and bringing an aqoueous solution for recovery at lower temperature than the raw material into contact with the other side of the membrane. CONSTITUTION:In the case where an ethanol-containing aqueous solution as a raw material and distilled water are respectively brought into contact with one side of a hydrophobic porous membrane and with the other side, gaseous layers 4, 6 are formed on the surface of the hydrophobic porous membrane and gas-liquid interfaces 3, 7 exist outer side of the layers. When the raw material 1 flows, a liquid boundary membrane exists in the liquid side and ethanol molecules move in the boundary membrane due to diffusion. When a gas and a liquid are not in the equilibrium state in the gas-liquid interface 3, ethanol and water are evaporated according to the gas- liquid equilibrium theory and move in the gas on the surface of the membrane and in the membrane owing to gas diffusion. As an apparatus, one by which the raw material solution and an absorption liquid are respectively brought into contact with one side and the other of a hydrophobic flat membrane is preferable.

Title: Control device by means of temperature of internal-combustion engine
Inventor: SHISHIDO TOSHIMASA
IPC: F01P7/04
Filed: 1982-12-27
Abstract: PURPOSE:To enable several actuators to be appropriately controlled by means of a single temperature sensing element and reduce the cost by inputting the output of said single temperature sensing element into one terminal of each of several comparators, to which a respectively different reference voltage is inputted through the other terminal. CONSTITUTION:When reference voltages V1-V4, which are supplied to the non- invertible terminal of each comparator C1-C4 respectively, are set in a relation of V2>V3>V4>V1 and an engine is operated, the outputs from the comparators C1-C4 are all at an L level, a transistor Tr1 is off, and transistors Tr2- Tr4 are on, while the engine is cool immediately after starting. Therefore, a radiator fan 3 is not operated and both the solenoids 4, 5 for automatic chokes A, B and the solenoid 6 for EGR control are on. Then, when the output V of a temperature sensing element 1 exceeds the reference voltage V2 as the warming up is advanced, the output of the comparator C2 reaches an H level and the solenoid 4 is turned off. When said output V becomes less than the reference voltage V3, the solenoid 5 is also turned off.

Title: Echo canceller
Inventor: MINAMI SHIGENOBU
IPC: H04B3/23
Filed: 1982-12-27
Abstract: PURPOSE:To reduce a tap length by using two echo concellers which eliminates the echo signal of a hydrid of 2-wire/4-wire conversion. CONSTITUTION:Echo cancellers EC1 and EC2 are used to erase each near-end echo signal and the far-end echo signal (flat delay signal) respectively. The outputs of these cancellers are added together to be converted into a pseudo echo signal, and this echo signal is subtracted from a reception signal. The flat delays are different on the line length, and therefore a training signal is sent from the transmission side. Then the flat delay selection switches 606 are successively selected based on the information of a convergence deciding circuit 611 to select an optimum tap. For instance, the flat delay of D'+D+delta(0<delta>D) can be eliminated at the position of the tap as shown in the diagram. Thus two cancellers of 50 taps each suffice for a canceller of 500 taps in terms of a single canceller.

CONSTITUTION: The outsides of adjacent steel pipe piles 1 are welded with welding heads 13 of welding machines 10 by traveling simultaneously in the same direction in the inside of each of the steel pipe piles 1 adjoined opposite. At that time, weld lines are formed lengthwise of the steel pipe piles 1, they are formed in parts submerged in sea water, river water, etc., of the steel pipe piles 1 to prevent the occurrence of a space between the adjacent steel pipe piles 1, and a pile wall with cut-off efficiency is formed. The adjacent steel pipe piles 1 are connected to each other with the weld lines to make it possible to drive the steel pipe piles stably as reaction force in the case a new steel pipe pile is driven.  In addition, because the steel pipe piles 1 have no joint for themselves, they are driven while revolving them to make it possible to drive the steel pipe piles 1 even into the ground having great sliding resistance. According to the constitution, the steel pipe piles are continuously driven and welded to make it possible to form the pile wall.
