Patent EP-0397149-A2 (EP)
Inventor: KUNIMOTO TOSHIFUMI C O YAMAHA
IPC: G10H5/00
Filed: 1990-05-09
Abstract: A musical tone waveform signal generating apparatus is used to generate the waveform signal full of variety which simulates the sound waveform of wind instrument. This apparatus provides a loop including first and second signal lines (L1, L2) through which the waveform signal is circulated so that its characteristic is to be varied. Both of first and second signal lines are connected to a conversion portion (100) which receives the waveform signal from second signal line and a musical tone control signal which is used to control a musical parameter of a musical tone to be generated. Then, the conversion portion effects the predetermined non-linear conversion on the waveform signal in response to the musical tone control signal so that a converted waveform signal to be obtained from the conversion portion is to be outputted to the first signal line. A transmission portion (300) to which both of first and second signal lines are connected transmits the waveform signal from first signal line to second signal line while at least delaying the waveform signal by a delay time corresponding to a pitch of the musical tone to be generated, so that a delayed waveform signal to be outputted from the transmission portion is fed back to the second signal line. Further, a signal loop portion (200) which is inserted between the conversion portion and transmission portion mixes the waveform signals on first and second signal lines by transmitting the waveform signal on one of first and second signal lines to the other of first and second signal lines.

Abstract: A gas flow type angular velocity sensor comprising two semiconductor substrates with all components formed thereon by use of a semiconductor technology and an IC technology, which are coupled with each other to form therein a pair of heat wires, a gas path and a nozzle holes for injecting a gas flow toward the paired heat wires in the gas path. Two heat wires of the pair changes their resistance-temperature characteristics in accordance with a deflection of the gas flow due to the action of angular velocity and a difference between two changed values is picked up and amplified by a resistance bridge circuit and an amplifier circuit formed on the semiconductor substrates to produce an output signal proportional to the angular velocity to be measured. A miniature pump formed on semiconductor substrates and drivable by a piezoelectric element provides a stabilized gas flow in the sensor. Thus constructed sensor is compact, accurate and suitable for mass-production and free from disadvantages of conventional sensors.

Abstract: A module for forming a conveyor belt which uses the center transverse connecting member to receive a driving force from an intermeshed sprocket is disclosed. Each of the modules (8) is suitable for being pivotally connected with a multiplicity of similar modules by pivot rods (10) to construct a conveyor belt. Each of the modules includes a plurality of elongated links (14) which extend the length of the module and which define a pivot hole (12) at each end which are aligned in the module to form first and second pivot axes. A portion of each link is not orthogonal to the pivot axes. The elongated links of each of the modules are joined by an integrally molded connecting structure (22) which extends transvers to the elongated links so as to maintain and join the relative position of the elongated links with respect to each other. The transverse member or connecting structures further define driving surfaces on opposite sides for receiving a driving force to move the module and the belt constructed from a multiplicity of the modules in two selected and opposite directions. In a preferred embodiment, the elongated links are selectively spaced by means of spacers integrally molded to one side surface of one of the plurality of link ends and a second group of spacers which are integrally molded to the other side surface of the second plurality of link ends. This maintains one side of the elongated links in contact with the opposite side of an elongated link of a pivotally connected module thereby allowing end-to-end reversability.

Abstract: An EPROM register is programmed in a manner substantially similar to the manner used to program a main EPROM array contained on the same integrated circuit. However, reading information from the EPROM register and the main EPROM array is accomplished differently. To use the data in the main EPROM array, it must be read out by applying appropriate address and output enable signals. Only during that read cycle is the data from a particular addressed location within the main EPROM array available on the data bus. In addition to the main EPROM array, an EPROM register is utilized which allows the data stored in the EPROM register to be available at all times.

Abstract: Polybutenyl substituted succinic acylating agents are formed by reacting (a) an acidic reactant represented by the general formula       R - CO - CH = CH - CO - R′          wherein R and R′ are independently -OH, -O-lower alkyl, a halogen atom, or taken together are a single oxygen atom, with (b) a polymer composed mainly or entirely of polyisobutene, at least 50% of the polyisobutene content of the polymer having an end group represented by the formula
       
 The mole ratio of acidic reactant : polymer is at least 1 : 1; and the reaction mixture is maintained under superatmospheric pressure during at least a substantial portion of the reaction period. The reaction rate is high, the yields of desired product are high, and despite the fact that superatmospheric pressures and elevated temperatures are used, the process forms only small amounts of tars or resinous co-products, even when employing as much as a 20% or more molar excess of maleic anhydride. Any unreacted acidic reactant such as maleic anhydride, maleic acid, fumaric acid, etc. can be, and preferably is, recovered from the reaction mixture, and thus is available for use either as recycle to the process or for other uses. Inasmuch as chlorine is not used in the process, the expense and difficulties associated with handling chlorine on a plant scale are eliminated, and the product is less corrosive than corresponding products formed by use of chlorine.

Abstract: A laser diode with a low reflectivity output facet provides infrared light to a nonlinear crystal resonator such that a portion of the infrared light is converted to blue light. A mirror is located on the opposite side of the nonlinear crystal resonator from the laser. The mirror allows the blue light to pass, but reflects the infrared light exiting the resonator back through the resonator and into the laser diode. The laser diode is thereby locked at the resonance frequency of the nonlinear crystal resonator.

Abstract: Still within the plate filter (10), a fluid medium, for example a gas, at a temperature of 60 to 300 DEG C is passed through the filter cake (47), which promotes the removal of liquid from the filter cake. The liquid portion contained in the filter cake of about 30 to 50 per cent can be almost completely withdrawn and reused. The treated filter cake is substantially free from liquid on withdrawal from the plate filter and can therefore be disposed of more readily and cheaply than hitherto. The reuse as filter aid is also possible since the particles virtually no longer adhere together but are almost once again in their original condition. The particles are therefore again able to form a highly porous filter cake. At least a part of the purified material can thus be reused so that the amount of waste material to be disposed of in landfill is greatly reduced. <IMAGE>
