Patent JP-S5872369-A (JP)
Title: Switching regulator
Inventor: KABUTO NOBUAKI
IPC: H02M3/155
Filed: 1981-10-27
Abstract: PURPOSE:To allow a switching regulator to output a constant voltage even at the time of voltage dropping by inserting a circuit which is different between at the forward operating time and at the reverse operating time in a control circuit which prevents the ON period of a main switching element from becoming longer than the prescribed value. CONSTITUTION:When a non-stable DC voltage from a terminal 1 decreases, the ON periods of an exciting transistor 12 and a TR27 become short, the base voltage of a TR29 increases, and the collector voltage decreases. Accordingly, a diode 34 becomes ON, the base voltage of a TR32 decreases, is converted via impedance, and is applied to a Zener diode 18, and the emitter of a TR19. When the emitter voltage of the TR32 becomes lower than the Zener voltage 18, the collector currents of operational amplifiers TR19, TR20 increase, thereby increasing the voltage drop of a resistor 11 to increase the base voltage of the TR12. Thus, the ON period of a TR2 is limited, thereby preventing the vanishment of the output. In this manner, the abrupt voltage drop is remedied by small discharging time constant of a condenser 35, and the ordinary voltage drop is remedied by the large charging time constant of a condenser 35.

Title: Original plate for direct lithographic type lithographic printing plate
Inventor: NAGASE KOICHI
IPC: B41M5/26
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain a negative type direct lithographic type lithographic printing original plate having excellent printing resistance and good image reproducibility while favorably maintaining good ink mileage, by incorporating hollow polymer fine particles in a heat sensitive layer in the original plate having the heat sensitive layer and an ink repellent layer on a base plate. SOLUTION: In the direct lithographic type lithographic printing original plate having a heat sensitive layer and an ink repellent layer on a base plate, the heat sensitive layer contains hollow polymer fine particles. A force applied to a plate material when printed is absorbed by the particles to alleviate a concentration of the force between the layers, thereby preventing a breakage of adherence between the layers. The polymer is resin fine particles having voids therein, and manufactured by expanding the particles by neutralizing an unsaturated carboxylic acid copolymerized by a volatile base or neutralizing a carboxyl group of a copolymer latex with a base and then adding an acid. Thus, the negative type direct lithographic type lithographic printing original plate having excellent printing resistance and good image reproducibility can be obtained.

Abstract: PURPOSE:To detect patterns of characters and symbols and punctuation by detecting pressure applied horizontally to a tip of a writing tool by two sensors and detecting its application direction, and measuring the length of the pressure application time. CONSTITUTION:A clip 7 and two pressure sensors 8a and 8b having gaps 9a and 9b in slight slanting directions are provided between the tip part 2 of the writing tool such as a ball-point pen and a main body 1.

The order of 0-3 and pressure application time intervals depending upon writing operation are stored and calculated by a CPU including an unshown timer and compared with the contents of a pattern memory. For example, ''7'' corresponds to ''3013''. When no output is generated for a specific time or longer, the dicrimination on movement to the next character is made. Thus, handwritten characters are identified easily with high precision.
