IPC: H03K3/357
Filed: 1989-03-28
Abstract: PURPOSE:To attain the use of a low voltage pulse and to facilitate high speed pulse oscillation by utilizing an oscillation characteristic of a microwave oscillation diode such as a gun diode or an IMPATT diode so as to add a pulse voltage to a DC voltage thereby forming a pulse operating voltage. CONSTITUTION:A DC voltage 101 is limited by a constant voltage circuit 1 and fed to a synthesis circuit 3 as a DC constant voltage 102. A pulse signal 201 is amplified by a pulse amplifier circuit 2 and the amplified pulse voltage 202 is fed to the synthesis circuit 3. The synthesis circuit 3 synthesizes the DC voltage 102 and the pulse voltage 202 and supplies a synthesized resulting output pulse 301 to a drive circuit 4. The DC voltage being a constant voltage synthesized by the synthesis circuit 3 is set to be an oscillated voltage point of a microwave oscillation diode. Then the pulse voltage is added to the DC voltage being the constant voltage and the entire voltage is set to an operating voltage point to attain high speed pulse oscillation.

Abstract: PURPOSE:To enable polishing work of high precision, by forming the surface of a through hole in a thick film multilayered wiring board surface on which a thin film layer is formed, to be the same surface as the board material surface of the thick film multilayered wiring board, or to be in a protruding step- difference of very small amount. CONSTITUTION:In a polishing work, colloidal silica whose mean abrasive grain 11 diameter is 80nm or smaller is used. The polishing pressure is controlled to be a specific value, and a thick film multilayered board 10 is subjected to polishing work. The step-difference between a board material working surface 20 and the through hole working surface 21 which is generated in the polishing work is set in the range of -0.5<=alpha<=+0.5. The working surface 21 of a through hole 9 and the working surface 20 of the board material 10 are desirable to be worked in the respective mirror surfaces whose surface roughness is 0.05mupmRa or less. In the both-surface polishing work, a plurality of dummy members are used, and a single member to be ground is worked.

Title: Plastic magnetic rotor
Inventor: ISHII HIROYUKI
IPC: H02K1/27
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To increase performance and reduce weight, by installing a magnetic flux density increasing means for increasing the magnetic flux density in a magnetic pole section of a plastic magnet section between the shaft and the magnetic pole section. SOLUTION: A magnet pole section 3 is connected to an inner cylinder 4 integrally formed with a shaft 1 by a connecting section 5. The connecting section 5 is provided with ribs 6A for increasing the strength and dimensional accuracy. Each of the ribs 6A becomes thicker as it comes closer to the outside. The thickness of the inner cylinder 4 side part of each rib 6A is determined with the securement of strength and moldability of plastic magnet considered and is made as small as possible. On the other hand, the magnetic pole section 3 side part of the rib 6A is determined with a quantity of plastic magnetic to be used and a pole pitch considered and is made as large as possible. Considering the balance of magnetic flux, the ribs 6A are located centering around a pole in the same number as the poles. Due to this structure, the ribs 6A can be used as a magnetic path and the magnetic flux density increases as in the case that the magnetic pole section 3 of the plastic magnet rotor and the entire rib 6 are formed thick, thereby increasing the performance and reducing a quantity of plastic magnet to be used and the weight.

Title: Musical element base voice synthesizer
Inventor: KAARU ROORENSU OSUTOROUSUKII
IPC: G10L13/04
Filed: 1981-05-25
Abstract: A phoneme-based speech synthesizer that is particularly adapted for implementation on a single integrated circuit chip includes a vocal tract model comprised of a fixed resonant filter and a plurality of tunable resonant filters whose resonant frequencies are controlled in accordance with the values of certain control parameters. A digital transition circuit is included which gradually transitions the values of the vocal tract control parameters as they change from phoneme to phoneme by iteratively adding to the current values a predetermined percentage of the difference between the current and target values. The vocal tract model is implemented utilizing a capacitive switching technique which eliminates the need for large valued components to achieve the relatively low frequencies of human speech. A glottal source generator is adapted digitally to generate a glottal pulse signal in a manner which readily permits the glottal pulse to be spectrally shaped in any desired configuration. <IMAGE>

Abstract: PURPOSE:To suppress the increase of NOX with the same effect as peripheral ignition by applying a center ignition system. CONSTITUTION:A combustion chamber 12 is provided at its center part with a spark plug (center plug) 18 that is to be the center ignition. A protrusion 24 is formed at the top face of a piston 22. This protrusion 24 is extended in the state of traversing the propagation path of a fire generated at the center plug, so that the propagation of the fire is suppressed by the protrusion 24. The peak generation of a heat release rate is suppressed by this deceleration of fire propagation, and the increase of NOX as well as peripheral ignition are suppressed. In addition to the center plug 18, a second spark plug 20 is provided at the peripheral part of the combustion chamber 12, so that ignition is performed according to the operating state (low load and high load) to prevent the degradation of combustibility due to the protrusion 24. The center plug 18 is changed in its ignition period by the degree of load. At the time of small load, the ignition period is made large compared to the large load time to assist the growth of the flame.
