Patent JP-S5797279-A (JP)
Title: Signal switching device
Inventor: TAKIZAWA AKIO
IPC: H04N5/44
Filed: 1980-12-09
Abstract: PURPOSE:To eliminate cross modulation distortion, by increasing the isolation between input and output, by outputting to a synthesis circuit after operating an amplifier at a normal voltage at the 1st signal reception, and disconnecting the 1st signal with non-amplification operation at the reception of the 2nd signal. CONSTITUTION:At a TV signal reception, for example, a power supply voltage 12V at a terminal 11 is applied to transistors Q1, Q2, and the base voltage VB makes normal amplification, 0.8V or more, and a desired channel signal from a terminal 16 is monitored and reproduced via a synthesis circuit 6. Next, at  VTR reproduction, the power supply voltage is switched to 2V and applied to  the collector of the Q1, Q2, and the VB is at 0.7V or less and an amplifier 5 is in off-state. Simultaneously, the isolation between the input and output is 60dB or more, the reception signal is interrupted and a VTR playback TV signal from a terminal 14 is not leaked to an antenna 1 and outputted via the synthesis circuit 6. Thus, the generation of cross modulation distortion based on the synthesis of the both signals is eliminated.

Title: Prevention of dc magnetic deflection of static induction apparatus
Inventor: FURUBAYASHI NORIO
IPC: H01F27/24
Filed: 1981-10-28
Abstract: PURPOSE:To prevent DC magnetic deflection without lowering magnetic flux density by utilizing an amorphous magnetic foil material having a high excitation capacity as an iron core. CONSTITUTION:An iron core of a static induction device such as a transformer which receives a DC field stress is formed with an amrophous magnetic material. It is designed so that it has the excitation capacity of 20-50 times as compared with that of conventional directional silicon steel belt and thereby satruation of iron core by field stress can be prevented. From the point of view of magnetic field circuit, large excition capacity is equivalent to the existence of air gap. Accordingly, a DC magnetic deflection can be prevented without lowering magnetic flux density.

Abstract: PURPOSE:To prevent the occurrence of signal current leakage and short circuit between connection terminals by making the shape of dummy terminal electrodes different from that of effective connection terminal electrodes and, at the same time, connection terminal electrodes which respectively have alignment marks and are arranged on a substrate on which an IC for drive is mounted to each other through an anisotropic conductive adhesive film. CONSTITUTION:Dummy electrodes 3 and 4 having a shape which is different from that of effective connection terminal electrodes 2 drawn out from picture element electrodes arranged on the surface of a glass substrate 1 constituting a liquid crystal panel are formed on both sides of the electrodes 2. Then an IC 9 for drive is mounted on the substrate manufactured based on a design having relativity to the electrodes 2, 3, and 4 and the electrodes 2 are connected to each other through an anisotropic conductive adhesive film 7 while the dummy electrodes 3 and 4 are sufficiently aligned so as to prevent the misalignment of the terminal electrodes 2 from each other at the time of connection. Therefore, the occurrence of short circuit and current leakage between each connection terminal can be prevented by preventing the misalignment of the connection terminals from each other.

Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To suppress an unsteady state of output by converting an optical signal into an electric signal, deciding whether an information signal is included in the electric signal and controlling the decision result output included in a prescribed frame. SOLUTION: A received burst optical signal is converted into an electric signal by a photodiode 1 and then converted into a voltage signal by a preamplifier 2. Then the differential signals S+3 and S-3 are outputted via an amplifier 3 having two output terminals of phases opposite to each other. An identification circuit 4 compares the potentials of inputted signals S+3 and S-3 and holds the potential difference peaks of these signals. A reset signals SRS is externally inputted to a peak holding element to initialize this element, and the identification level is controlled in each burst cycle. An output unsteady state is inhibited by the circuit 4, an inhibition circuit 5 and a control circuit 10 before the signal SRS is inputted and then the tip of a burst signal is detected.

Title: Constant low voltage circuit
Inventor: HASHIMOTO MASAMI
IPC: G05F3/24
Filed: 1980-12-10
Abstract: PURPOSE:To obtain a constant low voltage circuit in the area of a small pattern by providing with a circuit to dicide the currrent amplification ratio beta of each MOSFET taking out the difference between threshold voltages of two N- MOSFETs and applying a load current to them from their terminals. CONSTITUTION:Both P-MOSFETs 21, 22 work in a saturated area and the gate potential is common: therefore, the ratio of the current flowing in each FET21, 22 are equal to that between the current amplification ratios betap1 and betap2. Also, the current of the FET21 and 23 are equal, and there is same relation between the current flowing in the FET22 and that in FET24. And there is some relation also between the current flowing in the FET24 and the potential of an output terminal 25. The potential of this terminal 25 is related with all of the FETs 2 1-24, and the threshold voltage VTNH is the higher, the smaller current is applied to the FETs 21, 23, and also the smaller is the current flowing in the FET22. Further, the lower is the threshold VTHL, the nearer to -Vss the potential of the FET25 is. Thus, on the terminal 25, a constant voltage VTNH-VTNL that has no relation with the voltage of the power supply can be obtained.

Filed: 1992-07-02
Abstract: PURPOSE:To maintain excellent picture quality for a long time by using a specified polyester resin, magnetic powder, charge controlling agent, and coloring agent and adding a specified amt. of magnetic powder to the toner base material. CONSTITUTION:The toner base material consists of a polyester resin satisfying Mw/Mn>=20, wherein Mw and Mn is the weight average mol.wt. and number average mol.wt. of the resin, respectively, 0.5-5wt.% magnetic powder to the toner base material, 0.05-1wt.% charge controlling agent, coloring agent, polyolefin.

If Mw/Mn<20, large or small toner particles are produced because uniform dispersion of the charge controlling agent in the binder resin is not realized and the specified amt. of charge controlling agent is not incorporated. Thus, the obtd. toner can not be repeatedly used for a long time.

Abstract: PURPOSE:To make it possible to conform the existence of following documents by the form of a ruled line and at the same time, prevent data from being mistaken by changing a ruled line which is output to the bottom of a document if necessary, when a document consisting of documents is output. CONSTITUTION:A determination device 3 determines whether recorded data to be printed on the following document exists, when recorded data to be printed at the final printing position of document is read from a storage device 1. Then if the existence of the recorded data is determined by the determination device 3, an output ruled line change device 4 changes the shape of a ruled line to be printed at the final printing position. Accordingly, for instance, if a ruled line to be output to the bottom of a page is changed, it is possible to confirm easily whether the following pages exist by the shape of the ruled line. If the ruled line which is output to the bottom of a page is the same as an ordinary ruled line, it is possible to confirm the page as final. In addition, no particular characters are output, so data can be prevented from being mistaken.
