Title: Auxiliary steering for car
Inventor: SHIBAHATA KOUJI
IPC: G05D1/08
Filed: 1984-01-31
Abstract: PURPOSE:To improve the movement performance and steering stability by determining the amount of negative feedback according to the difference between the actual behavior of car which is represented by yaw rate or lateral acceleration speed and the aimed behavior of car which is to be generated through steering. CONSTITUTION:When front wheels 2 are steered rightward or a yaw rate is generated in the same direction by an external turbulence in no-steered state, a control circuit 7 operates a servovalve 36 to feed an oil pressure into the right- side sylinder chamber of an actuator 6. Rear wheels 26 are auxiliary steered in the same direction to that of the front wheels 2 or in the direction for offsetting the yaw rate generated by the external turbulence in no-steered state. When the steering input is zero, 100% feedback is applied, and the prescribed feedback is applied in steering, and the auxiliary steering is performed as prescribed previously, and the variation of the behavior of a car due to the external turbulence is perfectly eliminated in no-steered state.

Title: Am stereo receiver
Inventor: MAEKAWA MASAAKI
IPC: H04B1/10
Filed: 1981-02-04
Abstract: PURPOSE:To eliminate or reduce the impulsive noise which is caused to an angle demodulated wave during the overmodulation of amplitude, by avoiding applying the output of an angle demodulating means to a stereo signal reproducing means at least in an impulsive noise period. CONSTITUTION:An IFAM stereo signal which is received/converted 1 is applied to an envelope wave detector 3 and a frequency discriminator 4. The detector 3 demodulates the amplitude of the stereo signal and applies the signal to a matrix circuit 7 via a delaying circuit 5. At the same time, the discriminator 4 gives the demodulation of amplitude to the signal, and the output of the discriminator 4 is applied to the circuit 7 via an impulsive noise eliminating circuit 6. The noise level is slightly reduced for the input signal containing the impulsive noise at the circuit 6 through an LPF9, and at the same time this input signal is applied to an analog switch 10 with a delay of time t. On the other hand, the impulsive noise passed through an HPF11 is rectified 12 and then drives a mono-multi 13 with the voltage higher than a prescribed level. Then the switch 10 is turned off with a high-level output of a prescribed time. Accordingly the circuit 7 reproduces a normal stereo signal by a main signal L + R given from the circuit 5 and a secondary signal L - R given from the circuit 6.

Abstract: PROBLEM TO BE SOLVED: To surely detect an error caused by asynchronously generated noises or the like by checking the normality of address on a system bus during a period, in which the address is valid, asynchronously with a bus clock. SOLUTION: An address monitor part 17-1 is composed of high level set registers 34-1 and 35-1 and an incorrect address transition register 37-1. When asynchronous noises are generated during an address period, both the high level set registers 34-1 and 35-1 are set and the incorrect address transition register 37-1 is set so that an error detecting signal 26-1 can be asserted. Then, the error is reported to each central processing unit by an error reporting circuit, fault processing is performed and the incorrect address transition register 37-1 can be reset by a reset register 1 to be executed at the time of fault processing. Thus, at the address monitor part 17-1, the error can be detected asynchronously with the operating clock.

Title: Rubbery elastomer having surface slip characteristics
Inventor: KUSANO TAKAE
IPC: C10M107/42
Filed: 1984-01-30
Abstract: PURPOSE:To improve inexpensively the surface slip characteristics of a rubbery elastomer, by forming a high-slip material layer in which short fibers are dispersed on the sliding surface of a rubbery elastomer comprising rubber, synthetic resin or the like. CONSTITUTION:A high-slip material layer in which short fibers (e.g., cotton yarn or polyamide fiber) are dispersed is formed on the sliding surface of a rubbery elastomer, such as rubber or a synthetic resin, in elastic contact with, for example, a vehicle window glass. An example of the method for forming the high- slip material layer consists in dispersing a high-slip material powder (e.g., finely powdered tetrafluoroethylene resin or molybdenum disulfide) in a binder, further dispersing short fibers in the binder and coating the surface of a rubbery elastomer with the dispersion. In this way, no large-scale equipment is necessary, and the working can be performed simply and quickly and, therefore, the surface slip of a rubbery elastomer can be improved inexpensively.

Filed: 1985-02-01
Abstract: PURPOSE:To display exposure correcting information under easy-to-see conditions, by using a row display section composed of plural marks for displaying film feeding conditions also as the display section of set exposure correcting values. CONSTITUTION:A bar display section 18 for displaying film feeding conditions is also used for displaying set exposure correcting values. Therefore, index patterns 17 indicating numerous settable exposure correcting values can be constituted by means of one segment and, at the same time, the sizes of numerals indicating each value can be made relatively smaller. Accordingly, a liquid crystal display 7 can be miniaturized. Moreover, since the display of dot marks indicating set exposure correcting values is made through a means, such as lighting or blinking, which is different from the film feeding condition, what is set can be discriminated at once. In addition, since the display section is provided on the row, the range of settable exposure correcting values can be seen at once.
