Title: Synchronous detection circuit
Inventor: OGAWA HIROSHI
IPC: G11B7/00
Filed: 1979-01-22
Abstract: PURPOSE:To improve the recording density of a PCM signal on a recording medium by carrying error detection and correction into effect after passing a bit clock signal, extracted by a clock generating circuit, through a frame counter and word counter. CONSTITUTION:Binary reproduced data which never includes a frame-synchronizing signal or word-synchronizing signal is supplied to terminal 1 and clock generating circuit 2 extracts bit clocks. This signal is passed through frame counter 8 and word counter 9 to generate three word timing pulses Sw in each frame, and after error detection correction 5 and D/A conversion 6, right and left channel signals of a stereo audio signal are led out from output terminals 7L and 7R. Consequently, the need to insert a frame-synchronizing signal into data is eliminated, so that the recording density of a PCM signal on a recording medium such as a rotary disk can be improved.

Title: Automatic equalization system
Inventor: OZAKI TAKAYUKI
IPC: H04B3/14
Filed: 1982-01-19
Abstract: PURPOSE:To obtain a simple automatic equalization system by detecting distortion information on a spectrum from a transmitted signal and controlling the inclination of an amplitude equalizer. CONSTITUTION:A primary equalizer FEQ-N with negative characteristics and a primary equalizer FEQ-P with positive characteristics are connected to a transmission line TL and hybrid circuits H1 and H2 are used to divide a signal into two. Then, band-pass filters BPF1 and BPF 2 having narrow bands extract a signal. Detectors DET1 and DET2 perform detection and after DC amplifiers DCA1 and DCA2 perform amplification, the results are applied to the primary equalizers with less distortion. Thus, the spectrum is divided into a high and a low component about a frequency axis and those components are brought under automatic gain control independently to obtain a prescribed spectrum.

Title: Magnetic recording medium
Inventor: NARUSE SHIYOU
IPC: G11B5/70
Filed: 1983-01-18
Abstract: PURPOSE:To obtain a magnetic recording medium maintaining its high performance for a long term by incorporating a dispersant represented by a specified general formula into a magnetic layer. CONSTITUTION:Particles of gamma-Fe2O3, Fe3O4 contg. Co or gamma-Fe2O3 coated with Co are used as representative magnetic particles. A liq. for forming a magnetic layer is prepd. by adding at least one kind of dispersant represented by the general formula (where R is H or methyl, and n is 1 or 2) by 1-10wt% of the amount of magnetic particles.

Abstract: PURPOSE:To prevent the progress of deterioration in preservation at a high temperature by joining a semiconductor element with a die pad by the use of a silicon resin and performing bonding so that CuAl2, a junction metal compound, is formed at a junction part between an electrode and a metallic fine line. CONSTITUTION:When a die pad 14 of a lead frame is joined with an Si substrate 11 of a semiconductor element and a copper tine line 21 is bonded to an Al film 13 by the use of a copper ball 22, an alloy layer 31 of CuAl2 is formed at a junction part. In such a case, the speed of Cu atoms diffusing into Al atoms becomes high by causing the temperature ot the Cu atoms to be higher than that of the Al atoms or oscillations of the Al atoms to be larger than those ot the Cu atoms and then the formation of CuAl2 becomes more than ordinary formation of it. After that, the semiconductor device is sealed with an epoxy resin. The formation of CuAl2 compounds at the junction part between a metallic fine line and the Al film prevents the progress of deterioration in preservation at a high temperature.

Title: Photoelectric converter and semiconductor integrated circuit
Inventor: TAKAHASHI HIDEKAZU
IPC: H04N5/335
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To reduce a substrate bas effect such as the dispersion of the threshold values of MOS transistors, the lowering of amplification gains, etc., by making the well concentration of a MOS amplifier lower than that of a peripheral circuit. SOLUTION: When an amplifying MOS transistor 1 for a source follower circuit is operating, the GND potential is applied to a p-type silicon substrate 12, a p<+> buried layer 13, a p-type epitaxial layer 14, and a p-type well 15, and a source voltage VDD is applied to the n-layer drain of the amplifier MOS transistor 1. A P<-> layer of a low impurity concentration is grown epitaxially on a P<-> substrate, i.e., the amplifying MOS transistor 1 is formed in the substrate whose well concentration has been lowered. So the threshold dispersion of individual pixels lowers, and the dispersion of transfer conductances becomes small. Besides, the variations of the drain current becomes small even if the source voltage changes, and as the result a substrate bias effect becomes small.
