Title: Multiple transmitter/receiver
Inventor: KAWAI KIYOYUKI
IPC: H04N7/00
Filed: 1989-12-08
Abstract: PURPOSE:To enlarge the information amount of additional signals, which can be multiplexed in a transmission band, by dividing frequencies and multiplexing first and second additional signals in a temporal direction. CONSTITUTION:At the time of a moving image, the output of a multiplier circuit 216 is composed of a component (a) only. For a second field signal y to be outputted from an adder circuit 213 at the time of a still picture, components (b) and (c) are multiplexed while inverting two frames in respect to the component (a). When the component (a) as the additional signal is multiplexed with the component (b) and (c) mutually, these components are multiplexed in the temporal direction while dividing the frequencies. Thus, by using the transmission band required for multiplexing the component (a), the components (b) and (c) can be multiplexed further. Therefore, in the meaning of enlarging the multiplexing amount of the really required additional signal, the enlarging amount of the additional signal can be effectively enlarged.

Title: Space diversity receiver
Inventor: KITAZAWA AKIHIKO
IPC: H04B7/08
Filed: 1989-12-08
Abstract: PURPOSE:To expect the effect of in-phase synthesis even when dips occur in the neighborhood of the center of the signal bands of a main signal and a sub signal simultaneously by extracting a spectrum component in the neighborhood of the center of the signal band with a level detecting part, and performing the in-phase synthesis based on a level detection voltage. CONSTITUTION:A first main signal and a first sub signal are amplified with AGC amplifiers 41, 42, and are added on a phase difference detector 43. A second main signal and a second sub signal are synthesized with a synthesizer 14, then, the spectrum component of a synthetic signal in the neighborhood of the center of the signal band is extracted and detected with a band-pass filter 81 and a detector 82. A comparator 61 compares the magnitude of an inputted level detection voltage with that of a threshold value V, and sends a level detection signal when the level detection voltage is less than the threshold value. Therefore, the phase of the main signal is shifted in a prescribed direction, and a phase difference between the main signal and the sub signal occurs, and also, the level detection voltage is increased. When the in-phase state of the main signal and the sub signal is obtained, the control of a sub EPS (infinite phase shifter) is stopped, then, the in-phase synthesis is performed.

IPC: G11B21/21
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To increase rigidity of pitching and rolling and reduce tracking ability of a head by widening the width of a gimbal as a method of increasing yawing rigidity of gimbal in order to prevent occurrence of off-track by head slip.

Title: Image forming device
Inventor: SHIROKURA AKIRA
IPC: G03G21/10
Filed: 1993-12-20
Abstract: PURPOSE:To obtain an image forming device which ensures image formation after development and always ensures the formation of an image which is always stable, highly accurate and high quality by removing excess developer, existing on the surface of a belt-like photoreceptor, by means of a squeeze member after a development process but before a transfer process. CONSTITUTION:A squeeze roller 6 is pressed by the repulsive force of the belt- like photoreceptor 1, so that it abuts on the surface of the photoreceptor 1. After the development process but before the transfer process, the excess developer on the surface of the belt-like photoreceptor 1 is removed by the squeeze roller 6. That is, by finely adjusting the abutting of the squeeze roller 6 on the belt-like photoreceptor 1, the excess developer on the surface of the belt-like photoreceptor 1 is removed almost completely without disturbing a developed toner-image. Thus, because the excess developer on the surface of the belt-like photoreceptor 1 is easily and securely removed after the development process, ground soil and irregularities which are apt to occur in the belt-like photoreceptor 1 are prevented almost perfectly.
