摘要:
In a three phase load controlling system two bilateral switching circuits control the current in the first and the third phases; the first phase is later than the third. The second phase is uncontrolled. The gating signals applied to the bilateral switching arrangement connected in the first phase are advanced by a constant degree with respect to the voltage of the first phase. The gating signals applied to the bilateral switching arrangement connected in the third phase are synchronized with the voltage of the third phase.

A driving system for moving paths or escalators which use an endles chain adapted to be circulated between a path for transporting passengers, comprising a first and a second sprocket disposed at one end portion and substantially middle portion of the path, respectively, a first and a second induction motor coupled respectively to the first and second sprockets and each having the same rating output the sum of which is selected to be substantially equal to a maximum capacity of the system, an induction coupling interposed between the second sprocket and the second induction motor, means for detecting a current flow through the first induction motor, means for setting a reference value, and a thyristor amplifier for exciting the induction coupling in response to an excess developed when an output of the detecting means exceeds the reference value.
摘要:
An image communication apparatus is capable of communicating with external apparatuses. The image communication apparatus receives image data from a first external apparatus and stores the received image data in a storage unit. Upon receiving a request from a second external apparatus, the image communication apparatus identifies the image data that was destined for the second external apparatus among the image data stored in the storage unit and transfers the identified image data to the second external apparatus.

摘要:
An acousto-optic filter utilizing the far-off-axis anisotropic Bragg diffraction comprising an optically anisotropic crystal in which a light beam of incidence travels in a direction making a large angle with the crystalline axis and an ultrasonic wave travels in a predetermined direction. In the acousto-optic filter using a paratellurite crystal, the wavelength of the visible light is tuned by changing the frequency of the ultrasonic wave in a low frequency range below 100 MHz. The ultrasonic power required for driving the acousto-optic filter is about 1/500 that of the so far known acousto-optic filters. The bandwidth of the transmitted light can be changed from several angstroms to several hundred angstroms by selecting the incident angle of the light.
摘要:
In a high speed printing apparatus of the type in which ions produced between electrodes carrying a high voltage are passed through a mist of ink to cause selective particles of the ink to effect printing, there is provided an air circulating system in which the air containing the mists of ink is recovered, treated and again transferred to the printing portion.
摘要:
An image processing apparatus that is capable of executing a process efficiently by reducing a time required for the connection process to a host apparatus that has a high communication frequency among a plurality of host apparatuses connected by the WUSB communication. A generation unit generates connection history information based on information received from a plurality of host apparatuses connected. A detection unit detects a condition in which none of the plurality of host apparatuses is connected. A control unit selects a host apparatus of the highest communication frequency among the plurality of host apparatuses based on the connection history information when the detection unit detects the condition in which none of the plurality of host apparatuses is connected, and to perform a connection process to the selected host apparatus.
摘要:
A new and novel dot printer for printing characters of dot matrix or the like by sliding a slide member in the direction of a row, said slide member being provided with a plurality of dot printing elements which are arranged in line thereon at a predetermined distance, wherein plate springs are provided on both ends of the slide member as a guide, support and return mechanism so that guide, support as well as return power are assured for said slide member.
摘要:
A high speed printer in which ions produced between the high voltage impressed electrodes are modulated and then passed through an ink mist to electrically charge the ink particles to thereby print desired letters, figures, signs, etc., on a printing paper, characterized in that an electronegative gas containing a fluorine component and not containing any chlorine component is flown into the aperture board to prevent are discharge that would otherwise take place between the anode and aperture board.
