Title: Automatically closing door, method for regulating its speed, and method for braking the same
Inventor: KOISHI YOSHIHARU
IPC: E05F3/18
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To permit speed regulating action only during closing action, to open a door with a light force, and to prevent the door from being closed suddenly by regulating the speed of the door during closing. SOLUTION: The rotation of a gear 13 attached to a rotating shaft 12 linked to opening/closing of a door is transmitted to a speed regulating gear 18 and to a rotating shaft 19 linked to a speed regulating motor 20. A one-way clutch is interposed between the speed regulating gear 18 and the rotating shaft 19. The one-way clutch does not transmit torque from the speed regulating gear 18 to the rotating shaft 19 in a rotating direction (A) for opening the door, thus allowing the door to be opened easily by hand. The one-way clutch transmits the rotation of the speed regulating gear 18 to the rotating shaft 19 in a rotating direction (B) in which the door moves in the closing direction, thus driving and rotating the speed regulating motor 20.

Title: Detection of acetylene gas dissolved in oil
Inventor: KANBA MASARU
IPC: G01N21/35
Filed: 1987-10-05
Abstract: PURPOSE:To simply and continuously detect the acetylene gas dissolved in oil, by a method wherein the gas dissolved in insulating oil is allowed to transmit through a gas chamber through a fluorinated resin membrane and infrared rays having a wavelength of 2.9-3.2mum are further transmitted through the gas. CONSTITUTION:A valve 2 is provided to a part of the wall surface of an electric machinery 1 being an object to be detected and a gas chamber 4 is connected to said valve through a fluorinated resin membrane 3. Pervious windows 8, 9 are provided to the opposed places of the gas chamber 4 and the infrared rays having a wavelength of 2.9-3.2mum from a light emitter 6 are allowed to be incident to the gas chamber 4 through one pervious window 8 to be transmitted through the gas therein. The transmitted infrared rays transmit through the pervious window 9 to be received by a light receiver 7. The infrared rays are reacted only with acetylene gas to be absorbed corresponding to the concn. thereof. Therefore, when the intensity of the infrared rays incident to the pervious window 8 is compared and collated with that of the infrared rays transmitted through the pervious window 9 to detect the difference between both intensities, the concn. of the acetylene gas contained in the transmitted gas can be selectively detected even when other gas is mixed in said gas.

Title: Manufacture of copper-clad laminate
Inventor: YAMAKAWA MASAE
IPC: B32B37/10
Filed: 1989-09-27
Abstract: PURPOSE:To prevent fine foreign matters from adhering onto a copper foil surface by lowering a rectangular mirror plate with two sides on the horizontal surface and the other two sides slanted on the horizontal surface composed by overlapping prepreg and copper foil just as in the slanted state, and while its lower sides are brought into contact with the horizontal surface and then higher sides are lowered, placing a dust sucking nozzle on a open site and sucking. CONSTITUTION:A mirror plate 5 with its two sides horizontal and the other two sides slanted on the horizontal surface is lowered onto a prepreg and a copper foil 4 overlapped on a material structure bed 3, and lower side 6 is brought into contact with the copper foil 4, and then while a higher side 7 is lowered, the air flow between the mirror plate 5 and the prepreg and the copper foil 4 is sucked by a dust sucking nozzle 2 of a suction pump 1. When the horizontally placed mirror plate 5 is overlapped on the prepreg and the copper foil 4, foreign matters adhered to the prepreg are scattered all over together with the air flow. That is, when the mirror plate 5 in the slanted state is lowered, the foreign matters are scattered only in the direction of higher side 7. Therefore, the foreign matters can be sucked with good efficiency by providing the dust sucking nozzle at said position. Thus, the generating rate of recessed and projected marks of copper foil can be reduced remarkably.

Filed: 1988-10-04
Abstract: PURPOSE:To detect the freeze of liquid to be cooled in an early period and permit the release of the freezing of the same by a method wherein the control of the reduction of a capacity is effected when the amount of increase of the flow passage resistance of the liquid to be cooled in a cooler at every predetermined times has exceeded the preset amount of increase. CONSTITUTION:When the freezing of brine in a cooler 3 has begun, ice is adhered on the surfaces of flow passage walls and heat transfer tubes 9 and the sectional area of flow passages is decreased whereby a flow passage resistance between the inlet port 4 and the outlet port 5 of brine in the cooler 3 is increased. A microcomputer 7 operates the flow passage resistance at every predetermined times from the output of a pressure difference transmitter 6 and when the amount of increase has exceeded the predetermined amount of increase and has become abnormal, the microcomputer outputs an abnormality detecting signal to a capacity control device 8 to effect the reducing control of a capacity. According to the above-described constitution, freeze may be detected in an early period and the release of the freeze may be effected whereby the reliability of the detection of the freezing may be improved.

Therefore, the circuit production margin is increased, the area machining accuracy is relieved and accordingly a microstructure is attained.  As a result, the power consumption is reduced and a faster operation is attained for the semiconductor circuit.

Title: Synchronous motor
Inventor: MORITA MASAMI
IPC: H02K29/00
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent degradation in efficiency and make steep variation in amplitude in proximity to the zero cross point of magnetic field detection signals, by placing a plurality of pairs of magnets for rotational position detection, comprising different poles, at equal intervals so that the same poles of different pairs are positioned adjacent. SOLUTION: Pairs of a magnet 11a for rotational position detection and a magnet 11b for rotational position detection, different in polarity from each other, are placed on a support member 10 in proximity to each other at intervals of P1. In addition, the pairs are placed so that adjoining magnets 11a and 11b for rotational position detection in different pairs and of the same polarities are positioned at intervals of P2 wider than P1. As a result, a north-pole magnet 11a for rotational position detection and a south-pole magnet 11b for rotational position detection are placed in proximity to each other, and thus variations in amplitude in proximity to zero cross point become very steep.  Since the duty ratio of rotational position detection pulses obtained by shaping the waveform of magnetic field detection signals is stabilized at 50%, therefore deterioration in the efficiency of a synchronous motor can be suppressed.
