Title: Solid-state relay
Inventor: SUZUKI SEIJI
IPC: H03K17/78
Filed: 1986-12-27
Abstract: PURPOSE:To prevent malfunction of a main switching element without increasing number of components by connecting a malfunction preventing diode in series only between a cathode of an auxiliary thyristor and a DC minus side of a diode bridge. CONSTITUTION:With a high speed noise inputted between output terminals 1 and 2 in a solid-state relay, a switching element Q1 is reverse-biased and the state is transited from the ON-state before the high speed noise is inputted into the off-state. Then a minute current supplied from the DC side of the diode bridge DB flowed via a resistor R6 to the collector of the switching element Q1 is going to flow to the gate of the auxiliary thyristor SCR, since the malfunction prevention diode D is connected in series with the cathode of the auxiliary thyristor SCR, the current does not flow to the gate but flows to the switching element Q1 to prevent mis-trigger of the auxiliary thyristor resulting that the malfunction of the main switching element is prevented.

Inventor: IWASA TOKUAKI
IPC: A23L9/10
Filed: 1992-10-28
Abstract: PURPOSE:To produce custard pudding having caramel set at upper part having improved flavor because of direct eating from a container. CONSTITUTION:Upper caramel 21 is arranged as a whip caramel layer on a lower custard pudding 20 in a container 10. A custard pudding base for the lower custard pudding 20 is prepacked into the container 10. A foamable additive is added, whipped, whipped caramel having a specific gravity lower than the custard pudding base is fed onto the custard pudding base and the custard pudding base is heated and coagulated in a whipped state as it is to arrange the upper caramel 21 on the lower custard pudding 20. Since the additive has thermal coagulation property, the upper caramel 21 forms a very finely foamy layer state and flowing and dropping of the caramel by shaking of the container 10 is prevented.

Title: Paper coating composition and production of coated paper
Inventor: HAYANO SABURO
IPC: C09K23/00
Filed: 1994-12-16
Abstract: PURPOSE: To obtain a polymer latex which has a high suitability for high-speed coating and can give coated paper having a high surface strength by emulsion- polymerizing a monomer in the presence of a hypophosphorous acid or its salt. CONSTITUTION: A monomer is emulsion-polymerized in the presence of hypophosphorous acid or its salt to obtain the purpose polymer latex. The hypophosphorous acid or its salt acts as a chain transfer agent and reacts with the polymer. It is presumable that this agent can exhibit its effect in the reaction because it does not merely add to the terminals of the polymer but is incorporated within the polymer. Namely, it is presumable to be important that the phosphorus component is present in the polymer in the form of a dialkylphosphinate group of the formula, wherein R and R' are each the constituent of the monomer; and M is an atom or a group which forms a salt.

IPC: H02H3/05
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To enable reclosing in a multi-terminal transmission system, regardless of its being in the preceding end rest. SOLUTION: The closing condition of a closing setting 1 is set on a preceding end (hereinafter referred to as terminal A). The closing condition of a closing setting 2 is set on a succeeding end (hereinafter referred to as terminal B), when the preceding end is in operation but is set on the preceding end when the preceding end is in rest. The closing condition of a closing setting 3 is set on the succeeding end (hereinafter referred to as terminal C), regardless of its being in operation or at rest of the preceding end. Since the rest end setting is '0', when the three terminals are in operation without the end in rest, the output of a NOT gate 5 becomes '1'. Then, via AND gates 6 and 8 and OR gates 9 and 10, the terminal A turns into the preceding end, the terminal B is the succeeding end and the terminal C is the succeeding end, enabling reclosing.  Since the preceding end setting is '1' when the terminal A is set as the rest end, the preceding end setting is '1', the terminal B is the preceding end, and the terminal C is the succeeding end, thus enabling reclosing.

Title: Phase decision rectifier constitution with integration effect and pll with voltage-controlled oscillator utilizing the same
IPC: H03F1/30
Filed: 1992-10-29
Abstract: PURPOSE: To constitute the PLL with irreducible circuit elements and to structure it as an integrated circuit even when the time constant is extremely large in integrating operation. CONSTITUTION: Corresponding to an instantaneous value of a control signal T, a 3rd capacitor C3 is connected by a switching means SW in parallel to a 2nd capacitor C2 and supplied with a reference voltage. When both the capacitors C2 and C3 are connected in parallel, negative feedback effect becomes larger and an output signal becomes smaller at the time of a specific input signal VIN as compared with negative feedback through only the capacitor C2 . Further, the output signal VOUT depends upon the phase difference between the input signal VIN and a control signal T. When both the signals are in phase with each other, the output signal VOUT with a constant mean value is generated and when both the signals are out of phase with each other, the output signal VOUT varies in mean value. This circuit constitution has both effects of phase decision making and integration.
