Title: Switching power circuit
Inventor: YANO YASUSHI
IPC: H02M3/28
Filed: 1990-05-22
Abstract: PURPOSE:To reduce a loss brought forth when a semiconductor switch is put in continuity, by generating a driving waveform of a voltage being higher than an input voltage by rectifying a voltage generated in a tertiary winding of which the number of windings is larger than that of a primary winding. CONSTITUTION:A voltage VIN of an input DC power source 1 is supplied to an output voltage control circuit 2 and a bypass capacitor 3 through a diode 8. Since the number N3 of windings of a tertiary winding of a voltage conversion transformer 5 is larger than the number N1 of windings of a primary winding, on the other hand, a voltage between a terminal 5C1 and a terminal 5C2 of the transformer 5 is larger than the one between a terminal 5A1 and a terminal 5A2. Accordingly, an inter-terminal voltage of the bypass capacitor 3 is higher than the voltage VIN of the input DC power source 1 and a voltage VG of a terminal 2D of the output voltage control circuit 2 is higher than the voltage VIN of the input DC power source 1. In other words, a voltage for driving a semiconductor switch 4 turns to be high. Thereby a loss can be made low when the semiconductor switch is put in continuity.

Title: Fire alarm
Inventor: TAKAKURA SHIN
IPC: G08B17/00
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To grasp the approximate level of the generation of a fire by varying the sound volume of an alarm means according to variation in the density and temperature of smoke. SOLUTION: When smoke enters a fire alarm 1 and reaches density almost corresponding to a prediction level, a smoke density decision part 11 outputs a voltage corresponding to the density to an output control part 12. The output control part 12 outputs a voltage to a transistor Tr1 , which is turned on. Then the potential at a voltage division point drops and an IC 22 for alarming detects this voltage drop and outputs a voltage from a terminal 2 to a buzzer 21. The buzzer 21 makes a sound loud enough to be associated with the prediction level. When smoke of high density enters the fire alarm 1 as the fire expands, the smoke density decision part 11 outputs a voltage corresponding to the density to the output control part 12. The output control part 12 quits outputting the voltage to the TR Tr2 and outputs a voltage to a TR Tr2 .  The potential at the voltage division part drops and the IC 22 for alarming detects that and outputs a voltage from the terminal 2 to the buzzer 21, which sounds loud.

Abstract: PURPOSE:To prevent the missing print or the damate of a printing ribbon by detecting the running abnormality of the printing ribbon, by mounting an electrode for detecting the running abnormality of the printing ribbon and a means for detecting the contact of the printing ribbon with said electrode. CONSTITUTION:An abnormality detecting electrode 2 is provided to a printing head 1 and has an electrode 2-a above the route of a printing ribbon 3 and an electrode 2-b below said route. When the ribbon 3 contacts the abnormality detecting electrode 2, since a voltage higher than the potential of the printing ribbon is applied to the emitter of a transistor 11, a current flows to an ink ribbon from the emitter through the base of the transistor 11, a resistor 10 and the abnormality detecting electrode 2. The transistor 11 comes to an ON- state by said current and a current flows to a collector and resistors 12, 13 from the emitter. At this time, when the resistance value of the resistor 13 is set to a proper value and an inverter 14 is driven, the output thereof comes to a low level and, by monitoring this value, the contact of the printing ribbon with the abnormality detecting electrode 2 can be detected.

Abstract: PURPOSE:To improve a workability and a work speed by letting fall the cut-out concrete segments into a bucket hanging into a cavity, by descending the bucket to a bottom part of the cavity and by opening a center part of the bucket to transfer the segments to a carrier cart. CONSTITUTION:A back side of a concrete structure 1 is cut out to a predetermined thickness by a cutting nozzle 17 and the cut-out parts are vertically cut again at an even circumferential cutting distance. A taking-out bucket 40 with its circumferential side 42 being opened, is pressed to a side wall of a cavity 2 and is fixed at a predetermined position.

When a certain amount of the segments is stored in the bucket 40, the circumferential side 42 is closed and descended to a bottom part 1b of the cavity to load the segments to a carrier cart 54 with its center part 43 being opened. Then, the carrier cart 54 is moved to outside the structure 1 and the segments are transferred to a container vessel. A slurry collected into a water collection pan 60 is introduced to an abrasives separator to recollect the abrasive material and then is solidified and disposed.

Title: High-molecular link between methotrexate derivative and pyran copolymer and its production
Inventor: HIRANO TAKASHI
IPC: A61K47/48
Filed: 1993-05-11
Abstract: PURPOSE:To obtain the subject new low toxic high-molecular link or a salt thereof having excellent carcinostatic activity. CONSTITUTION:This high-molecular link is made up of 10-500 recurring units of formula I and formula II (R is a methotrexate residue of formula III or IV; (n) is 1-12) with the molar ratio of formula I to formula II of (0:100) to (90:10). The high-molecular link is obtained by the following processes: methotrexate is reacted with an alkyldiamine to synthesize and isolate a methotrexate derivative, which is, in turn, reacted with a pyran copolymer in a water-soluble organic solvent. The high-molecular link gradually releases the methotrexate derivative as a carcinostatic substance in the serum, having markedly excellent carcinostatic activity as compared to the single use of methotrexate, owing to the synergistic effect between carcinostatic methotrexate and carcinostatic pyran copolymer.

Abstract: PURPOSE:To prevent the diffusion of an image generated by repeating binarization and multilevel conversion by extending a shape of an opening at the time of multilevel conversion in the same direction as an error diffusion matrix, in the case of converting an image binarized by an error diffusion method to multilevel. CONSTITUTION:A binary image to be converted to multilevel is read in succes sively to a line buffer 101 at every raster. In this case, to each latch 102, a picture element corresponding to a multilevel conversion opening 603 is latched, and outputted to A2 - A14. The outputs A2 - A14 of each latch in this case are inputted to an address line of a ROM 103, and a multilevel estimated value set in advance to the ROM is outputted. Also, as for the contents of the ROM in this case, multilevel data corresponding to density of dots in a multilevel conversion matrix 603 is set in advance. As for the multilevel conversion opening 603, it will suffice that it is a shape for extending in the same direction as a diffusion matrix 403. By setting weighted data corresponding to a dot position, the multilevel conversion can more exactly be executed.
