Title: Pwm controller
Inventor: KUBOTA YUZURU
IPC: H02M1/08
Filed: 1994-06-13
Abstract: PURPOSE:To operate a PWM control power converter stably by generating a carrier signal having no distortion in the waveform in a carrier synchronization system for controlling a modulated wave signal and a carrier signal synchronously. CONSTITUTION:In the PWM converter 1 for controlling a carrier signal and a modulated wave signal synchronously, the carrier signal is generated based on a correction signal phi operated from voltage commands Vd*, Vq* for controlling a sync signal theta of an AC power supply 3 and an input voltage vector of the PWM converter 1 wherein ripples are removed from the correction signal phithrough a filter circuit 19. This constitution realizes efficient and stabilized operation of a power converter while suppressing the higher harmonics.

Title: Automatic broadcasting device
Inventor: HAYASHI YOSHIROU
IPC: G10L13/04
Filed: 1978-10-23
Abstract: PURPOSE:To secure the output of the signals corresponding to the prescribed broadcast sentence by dividing the intermediate recording part into the group into which the aural signals sent from the aural recording part are written with an optional ratio and the group from which the aural signals are read out for control and then reading the aural signals in sequence from the intermediate recording part. CONSTITUTION:Aural recording part 100 consists of the memory which records the aural signals of the contents required for broadcasting by dividing those signals into the fixed syllables, words and the like and also can give the independent writing and reading control to at least more than three units of the aural signals, and possesses the intermediate memory groups featuring the general memory capacity shown in the equation. On the other hand, intermediate recording part 200 gives the control to the aural signals sent from part 100 by dividing them into the group into which they are written with an optional ratio and the group from which they are read out. Thus the aural signals are read out sequentially from part 200 to deliver 300 the signals corresponding to the prescribed broadcast sentence.

Title: Magneto-optical garnet
Inventor: OIKAWA TORU
IPC: G02F1/09
Filed: 1988-05-30
Abstract: PURPOSE:To enable the decrease of a light loss per 45 deg. Faraday rotational angle in a 0.8mum band by growing a specific crystal by liquid phase epitaxy and forming the same on a TSGG substrate. CONSTITUTION:The crystal expressed by the chemical formula A3B5O12 grown by the liquid phase epitaxy is formed on the terbium-scandium-gallium-garnet (TSGG) substrate having 12.510-12.525A lattice constant at 740 deg.C from a lead oxide-bismuth oxide-boron oxide flux held in a platinum crucible. In the formula, A denotes Gd and Bi and B consists essentially of Fe and denotes Al and Ga. The substitution quantity of Bi is, therefore, increased to the larger quantity than in case of using the conventional substrate. The decrease of the light absorption loss per 45 deg. Faraday rotational angle is enabled in this way with the Faraday rotor material used for optical parts of 0.8mum wavelength.

CONSTITUTION:A diaphragm 10 of an ink jet head is so constructed as to laminate three layers of a first layer 1 on an ink chamber side, an intermediate layer 16, and a third layer 17 on a piezoelectric element side. For the first layer 15 in contact with ink, a contact angle with the ink is sufficiently less than 90 deg., and there is no problem in a property of filling the ink chamber with ink. Tetrafluoroethylene composing the second layer 16 makes the contact angle with the ink 90 deg. or over, and there is substantially non-transmnission of water vapor. A vibration part 18 of the third layer 17 of the diaphragm 10 is insularly formed at a position corresponding to the ink chamber, and a fixing part 19 is formed in a ladder state having a specific appropriate interval L from the vibration part 18. Besides, the fixing part 19 is connected to the piezoelectric element. Further, though micro pinholes are generated in the second layer 16, the ink through the pinhole can be prevented from permeating from an outside.

Title: Cathode ray tube
Inventor: KIMURA MASAMICHI
IPC: C09K11/08
Filed: 1987-05-27
Abstract: PURPOSE:To prevent a change in the luminescent color of a face plate from occurring between a time when stimulation is effected with an electron beam and a time immediately after the stop of the stimulation, by forming a monochromatic light emitting, long-afterglow phosphor film, from which cathode ray tube screen is produced, with a mixture of P27 phosphor and P1 phosphor. CONSTITUTION:P27 phosphor having a composition of formula I as a red light emitting phosphor is mixed with P1 phosphor having a composition of formula II as a green light emitting phosphor to form a monochromatic light emitting long-afterglow phosphor film from which a screen is produced. Since the time taken for the brightness to decrease to 10% of an initial value after the stop of electron-beam stimulation is 25msec with both P27 phosphor and P1 phosphor, a monochromatic light emitting phosphor film formed from a mixture thereof not only emits a yellow light by stimulation with an electron beam but also keeps yellow without turning to green or red even after the stop of the electron beam stimulation.
