Title: Intake device of engine
Inventor: ARAKI MAKOTO
IPC: F02M35/12
Filed: 1990-05-01
Abstract: PURPOSE:To effectively reduce a synchronizing intake noise in idling in a compact structure by connecting a resonance type noise eliminator which eliminates noise through resonance with a synchronous frequency of a pressure vibration characteristic of the upper stream of a throttle body, from an intake passage at the upper stream of the throttle body to a branch idle passage. CONSTITUTION:In an intake device constituted by an air cleaner 7, an upper stream intake passage 8, a surge tank 8 and an independent intake passage 6 of each cylinder, the upper stream intake passage 8 is constituted in such a structure that its columnar vibration characteristic is synchronized with a pressure vibration frequency generated corresponding to an intake pulsation at an engine revolution number in idling and excited according to setting of the length and area of the passage. And in order to attenuate pressure vibration in idling, a resonance type noise eliminator 29 which resonates with a synchronous frequency and eliminates noise is connected to an idle passage for supplying an intake in idling with bypassing a throttle body 15. This resonance type noise eliminator 29 is constituted by a pipe member 30 made of a rubber and so on, and its one end part 30a is connected to a curved part of the idle passage 25.

Title: Signal filter device
Inventor: WAKI OSAMU
IPC: H01F19/00
Filed: 1980-08-21
Abstract: PURPOSE:To make narrow the noise band of a transmission line inputted to an SCF (switched capacitor filter) of a reception side device, without losing the amplitude characteristics of an input signal, by transmitting the input signal through differentiation and outputting this transmission signal through integration. CONSTITUTION:The high band component of an input signal given to a transmission side input terminal 1 is emphasized at a differentiation circuit 13 and it is given to a band limit filter 2 and becomes a signal within the transmission band width to be applied to the transmission line. The signal added with noise at the transmission line enters an input terminal 4 of a reception side device and the high band of the signal is attenuated at an integral network 14 and the noise is attenuated from the lower end of the input signal. Thus, the input signal of the SCF6 has narrow noise band, and even if the clock frequency of the SCF6 is set lower by the value, the effect of a clock folding response on the SCF6 due to noise can be less.

Abstract: PURPOSE:To attain a successive serial input by providing a pair of registers, performing the serial input and output in one of the pair, transferring data to a memory cell array in the other of the pair and preparing the next serial input and output. CONSTITUTION:For instance, when serially outputting, a display controller 51 initially sets a selection signal LRS to '0' to select an (a) side, reads and transfers data B to the data register 31a from the memory cell array 1a and in this case, the start address of the data B is not designated. Then, the selection signal LRS is set to '1' to select a (b) side and the data A is read and transferred to the data register 31b from the memory cell array 1b. Under this state, if the display controller 51 sets a serial enable signal SEN to '1', a serial output mode signal SOM is outputted from an AND gate, it is supplied to the enable ends of data buffers 67a, 67b and as a result of this, the outputs of the data registers 31a, 31b are supplied to serial data gates 66a, 66b.

Abstract: PURPOSE:To offer a glass antenna with less gain fluctuation and also less in the directivity over the entire reception frequency band from a medium wave to an ultrashort wave such as for FM broadcast by adopting a specific shape and configuration for an antenna provided on a rear window glass of an automobile. CONSTITUTION:An antenna wire group 7 is provided on the upper part of a conductor wire group 2 for heating and a received radio wave is led out to a preamplifier 9 from a feeding point 8. The antenna wire group 7 consists of a main antenna comprising three antenna wires 12a, 12b and 12c in parallel with each other and auxiliary antenna wires 13a and 13b. The 13a is arranged axis symmetry with respect to a center axis 16 of the window glass 1, an output is extracted from its nearly midpoint and given to a coupling point B being a location shifted from the center position of the 12b by means of a jumper 15.

IPC: H02P7/292
Filed: 1983-06-29
Abstract: PURPOSE:To improve the responsiveness for the variation in a load of a speed by calculating the compensation amount of a current command in response to a deviation between a speed command and the actual speed of a motor, and adding it to an input command of a current control system. CONSTITUTION:An automatic speed control system 9 calculates a current command I in response to a deviation epsilonp between a speed command omegap and the actual speed (omega). A compensation calculator 15 calculates a compensation current Ip from the value produced by multiplying the speed deviation epsilonp by reverse function of a transfer function exhibiting the counterelectromotive force coefficient and inertial amount. An automatic current control system 11 controls a thyristor power source 2 in response to a deviation between the command I, the current Ip and a motor current. In this manner, even if a load abruptly varies, a controller of a motor having good speed responsiveness can be provided.

Filed: 1988-05-13
Abstract: PURPOSE:To stabilize sound volume due to AGC gain and to enhance a speaking quality by stopping the updating of the AGC gain when mean power at the time of transmitting signal detection as a voice is larger than frame power by a constant value. CONSTITUTION:The mean value of the inter-frame power having the dispersion of the transmitting signal recognized as the voice by a voice detecting part 1 is obtained by a mean power calculating part 3. The obtained signal mean power is compared with the inter-frame power outputted from the voice detecting part 1 by a comparing part 4. As a comparison result, when the mean power is larger than the inter-frame power, and their difference is >= a prescribed dB, it is judged that the inter-frame power is not that at a normal time, and even when the inter-frame power exceeds the voice detecting threshold, the AGC gain is not updated. Further, the comparing part 4 instructs an updating part not to calculate the inter-frame power, and the AGC updating part instructs an AGC amplifier not to update the AGC gain.
