Title: Space diversity reception system
Inventor: ATSUTA HIROSADA
IPC: H04B7/08
Filed: 1990-07-02
Abstract: PURPOSE:To prevent S/N from deterioration by prohibiting the synthesis when a 3rd reception input level is lower than an in-phase synthesis output of two reception input signals. CONSTITUTION:A switching control circuit 1 detects the signal level of a reception input signal C based on the AGC voltage of an AGC amplifier 44 to control the switching of a switch 2. Thus, when the signal level of the signal C is decreased lower than a prescribed level, since the gain of the AGC amplifier 44 is changed to change the AGC voltage, the reduction in the signal level is decided by the voltage to changeover a switch 8, then the reception input signal C is forcibly brought into 0 so that the synthesis of the reception input signal C at a synthesizer 32 is not implemented. Thus, the deterioration in the S/N of the in-phase synthesis output of 1st and 2nd reception inputs is prevented.

Title: Magnetic thin film body
Inventor: YOUDA HIROSHI
IPC: G11B5/39
Filed: 1982-10-04
Abstract: PURPOSE:To enable to form a magnetic anisotropy of an arbitrary size in an arbitrary direction by a method wherein a stripe form unevenness arranged in a fixed direction is formed on one surface of a magnetic thin film body. CONSTITUTION:A ferromgnetic thin film 1 composed of a ferromagnetic material is formed on a substrate 2, photo resist patterns 3 in stripe form are formed thereon. Next, grooves are formed by etching the thin film 1. By the surface unevenness formed in such a manner, the magnetic anistropy is generated in the thin film 1 in the direction of an arrow A. Since the unevenness is thus formed on the surface of the thin film 1, the magnetic anisotropy of an arbitrary size can be formed in an arbitrary direction by selecting a direction and a depth of formation. Besides, this anisotropy is a shape anisotropy and therefore does not disappear after exposure to high temperature.

Title: Contact pin
Inventor: IGARASHI SHINICHI
IPC: H05K1/18
Filed: 1988-07-14
Abstract: PURPOSE:To prevent an electrical part from increasing in size due to the increasing number of signals to be transmitted by a method wherein two kinds of signals in an electrical part are transmitted by one contact pin. CONSTITUTION:Among conductors 2, 4 and an insulator 3, a connecting terminal 41 of the conductor 1 is fitted into a hollow of the insulator 3 and the insulator a is fitted into a hollow of the conductor 1 so as to constitute a contact pin. The conductors 2, 4 are thus electrically insulated by the insulator 3. This enables a signal of a line 6 in an electrical part to be transmitted to a substrate line 13 and a signal in a line 5 in the electrical part to be transmitted to a substrate line 14 simultaneously. Two kinds of signals can be thus transmitted by one contact pin so that increase in size of the electrical part can be avoided even if the number of signals to be transmitted increases.

IPC: H04B10/00
Filed: 1980-12-15
Abstract: PURPOSE:To stabilize an optical output and reduce the distortion, by providing a filter, whose gain is higher in the low frequency region and is lower in middle and high frequency regions, in the loop of an optical signal modulating circuit having the negative feedback loop. CONSTITUTION:A part of the optical output of a luminous element 1-1 is received by a photodetector 1-2, and the photoelectric conversion output signal is fed back negatively to a difference circuit 1-4 through an amplifier 3-1 and lag lead filter 3-2. In respect to the gain frequency characteristic of the filter 3-2, the gain is higher in the low frequency region and is lower in middle and high frequency regions. Consequently, features of the optical output stabilizing loop which is low-frequency but requires a high gain and the distortion reducing loop which is low-gain but requires a wide band are provided. The phase rotation quantity of the wide-band loop circuit cancels the phase delay due to the lag characteristic in the low frequency region and the phase advance due to the lead characteristic in middle and high frequency regions, and therefore, unstability is prevented.

Filed: 1982-10-06
Abstract: PURPOSE:To decode easily and quickly the consecutive shooting speed information in a reproduction mode, by coding and recording the consecutive shooting information within an H period included in a vertical blanking period of a video signal. CONSTITUTION:A timing circuit 16 sends the first shutter trigger pulse to a shutter control circuit 5 after the start of working, and the circuit 5 opens a shutter 3 for a period corresponding to the light quantity received by a light quantity sensor 14. Thus the first one frame is fetched into an image pickup element 4. Then the circuit 5 closes the shutter 3 and informs the circuit 16 that the image pickup is over with the first one frame. Thus the circuit 16 sends a write trigger pulse of a prescribed time point to a record control circuit 8. The circuit 8 writes the picture signal of the element 4 to a buffer memory via a picture signal processing circuit 6 and supplies the contents of the buffer memory to a writing head 10. As a result, a synchronizing signal, the consecutive image pickup speed information and a picture signal are written successively to a magnetic disk 9.
