IPC: H01Q1/38
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To electrically vary the directivity of a microstrip antenna, which has a base plate formed on the backside of a dielectric substrate and many radiation elements formed on the top surface side, without reducing antenna gain. SOLUTION: Signal transmission lines L1 to L4 which are coupled with the respective radiation elements S1 to S4 in terms of AC and disconnected in terms of DC are provided and bias voltage control circuits M1 to M4 apply a bias voltage selectively to the signal transmission lines L1 to L4 through bias lines K1 to K4. Consequently, the specific dielectric constant of the dielectric substrate 23 in the area between the signal lines L1 to L4 and base plate 22 varies to cause propagated high-frequency signals of the signal transmission lines L1 to L4 to shift in phase, thereby actualizing a radiation pattern by which desired directivity can be obtained.

Abstract: PURPOSE:To suppress a discordance in the state between an encoder and a decoder and to improve the quality of a reproduced sound at a low cost by performing a linear predictive analysis by the linear predicting unit of the decoder by using a function generated by adding a constant to autocorrelation of (0)th order. CONSTITUTION:A subtracter 1 outputs the difference between an input signal X(t) and a prediction signal and a quantizer 2 quantizes and encodes the difference to generate a code word C(t). This code word C(t) is sent to the decoder (b) and also inputted to an inverse quantizer 3 to restore the original difference value, and an adder 4 adds it to the prediction signal to generate a reproduced signal X'(t). This X'(t) is inputted to the linear predicting unit 6 at the same time to generate a prediction signal. The decoder (b) once inputting C(t) inversely quantizes it by an inverse quantizer 6 and adds it to the prediction signal from a linear predicting unit 8' by an adder 7 to generate a reproduced signal X'(t). This X'(t) is inputted to the linear predicting unit 8' and used to generate a next prediction signal.

IPC: H03K5/135
Filed: 1993-03-16
Abstract: PURPOSE:To reduce power consumption by detecting a timewise intermediate position where a state that the latched data of respective stages coincide with a prescribed pattern continues and defining input data delayed until the intermediate position as formal input data. CONSTITUTION:The data provided with specific patterns such as a frame pattern or the like are latched by a latch means 20 and it is defined that the data are normally latched when coincidence with the specific pattern is judged in a pattern judging means 30.

Title: Developing device with magnetic brush
Inventor: FUKUDA AKIRA
IPC: G03G15/00
Filed: 1982-04-05
Abstract: PURPOSE:To reduce the change in a developing density due to the affect of ambient temp. by changing the gap between a photosensitive drum and a nonmagnetic sleeve and controlling the output of a developing bias electric power source according to the change in the ambient temp. CONSTITUTION:When the ambient temp. rises, an actuator 13 is pressed rightward by a coil spring 14 and a developing device 3 rotates around a revolving shaft 11, thereby widening a developing gap (g). When the temp. lowers, the spring 14 contracts and a bias spring 15 elongates, thereby narrowing the gap (g). Since developing bias current IB and developing density D are proportional, the apparent electric resistance of a toner 6 is changed by changing the gap (g), whereby the current IB is regulated. On the other hand, the change in the current IB is detected with a current change detector 16, and the developing bias voltage is changed with a voltage control device 17 to control the bias current IB so as to decrease the change thereof. Thus, the change in the developing density due to the affect of the ambient temp. is reduced.

Abstract: PURPOSE:To eliminate disturbance caused by back scattered light and to obtain a sharp image by equalizing the cutoff wavelength of a specific mode of an image fiber to the specific wavelength of illumination light which excites an object to fluoresce. CONSTITUTION:An image fiber part 1, the core part 3 of a light guide, and clad parts 2 and 4 provided in contact with the core part 3 are formed coaxially in one body.
