Title: Car stabilizer device
Inventor: YOKOTE MASATSUGU
IPC: B60G17/015
Filed: 1990-04-26
Abstract: PURPOSE:To enhance the comfort in sitting in a car cabin, secure rolling stiffness, and provide controllability for it in accordance with the running condition by equipping a car with a stabilizer device of fluid pressure type, and therein controlling the internal pressure of the stabilizer according to the car running condition. CONSTITUTION:A controller 36 reads sensing signals G from a crosswise acceleration sensor 38 and judges whether or not the reading value ¦G¦ is greater than the reference value G0. In the case of 'No', it is considered to be in a cornering state with a small crosswise acceleration, and piston 30b of a control cylinder 30 is put in the neutral position. In the case of 'Yes', the piston 30b is moved in the direction of boosting the working pressure in compression side cylinder chambers U, L. This constitution prevents worsening of the comfort in car cabin even while running with bounces. Also the car steering characteristics under cornering can be controlled optimally.

Abstract: PURPOSE:To improve the precision of the estimated control by varying the set opening degree according to the difference between the car speed on the setting of the constant speed traveling and the set-up car speed, in the estimated control for opening a throttle to a set opening degree, before the constant speed traveling. CONSTITUTION:When a transition instruction from the ordinary traveling to the constant speed traveling is outputted by turning ON a setting switch 15b during the traveling of a vehicle, and a set state is realized, the transition to an estimated control subroutine is performed, and estimated control is performed. In other words, the opening degree of a throttle is opened by drive- controlling a servomotor 20 by the quantity (set-up quantity) which is set on the basis of the function between the car speed and throttle opening degree. Further, the difference between the speed at the time when the car speed (set-up car speed) which is realized on the start of PID control after the lapse of a prescribed time and the set car speed is calculated from the set-up quantity, and the set-up quantity is varied on the basis of the car speed deviation. When a cancellation signal does not exist, constant speed traveling is executed.

Title: Abnormality alarm device for electric load on vehicle
Inventor: SHIMIZU SUMIO
IPC: B60R16/03
Filed: 1982-06-30
Abstract: PURPOSE:To enhance the safety of an electric system on vehicle, by a method wherein an alarm is issued when an output from a load current detecting circuit connected to various electric load exceeds a threshold value determined by a dark current load, and the alarm is not issued when the electric load is changed over to a normal use. CONSTITUTION:In the case where an ignition switch IS is opened, when only the dark current load 2 is normally operated, the level of an output from an operational amplifier A2 of the load current detecting circuit 1 does not invert the output condition of a voltage comparator A3 of a comparing circuit 3. When abnormality is generated in the load 2, the voltage drop across a resistor RS in the circuit 1 is increased, so that the level of the output from the amplifier A2 is also raised, and the output condition of the comparator A3 of the circuit 3 is inverted. Therefore, a transistor T1 is turned ON to turn on a light-emitting diode LED, thereby issuing an alarm. In the case where the dark current load is normal, when the switch IS changed over to a terminal ACC, a relay contact YS is changed over to separate the load from the circuit 1, thereby preventing the comparing circuit 3 from actuating.

IPC: B32B3/12
Filed: 1989-04-28
Abstract: PURPOSE:To make shearing strength in a ribbon direction and that in a stretching direction almost same and to achieve wt. reduction by forming the shape of each of unit cells into such a flat hexagonal shape that the arrangement pitch dimensions in the longitudinal and lateral directions of the unit cell become almost same when a large number of the unit cells are arranged in a planar state. CONSTITUTION:A honeycomb core structure 10 is constituted by making a large number of unit cells 10a having a flat hexagonal shape continuous in longitudinal and lateral directions in a planar state. When the unit cells are made continuous in an x-direction (ribbon direction) and a y-direction (stretching direction), the dimensions of the respective parts of the unit cell 10 are set so that the arrangement pitch dimensions (c), (d) in the respective directions are almost same. By changing a hexagonal shape to a flat one so that the arrangement pitch dimensions (c), (d) in the longitudinal and lateral directions become almost same, shearing strength and the modulus of elasticity in shear can be made almost isotropic. As a result, the honeycomb core structure can be planned from the aspect of strength, rigidity and wt. without wastefulness and the wt. reduction of the honeycomb core structure can be achieved.

Abstract: PURPOSE:To adjust a middle-pitched sound by a simple constitution by connecting an attenuator having a resistance whose resistance value satisfies a prescribed relation, to an input side of a tweeter for forming a loudspeaker device together with a woofer. CONSTITUTION:A loudspeaker device is formed by a woofer 1 and a tweeter 2 whose resistance component is R0. As for this tweeter 2, an attenuator ATT having a variable resistance 3 which is connected in series to the tweeter 2 and has a resistance value R1, and a variable resistance 4 which is connected in parallel and whose resistance value is R2 is connected to its input side, and a transfer function G of the tweeter 2 becomes a value for satisfying the expressions I, II in accordance with a low pitch side and a high pitch side, respectively. In the expressions, a ratio (m)=R1/R2, and a ratio (n)=R1/R0. Accordingly, when the ratio (m) is kept constant and the ratio (n) is varied, the low pitched sound can be adjusted so as to be suppressed low without exerting an influence on the high pitched sound. As a result, the middle-pitched sound can be suppressed a little in order to improve the frequency characteristic, when reproducing a sound which is not a high fidelity sound of a TV broadcast, etc., by a simple constitution which does not require a resonance circuit, etc.
