Title: Switching power-supply circuit
Inventor: YOKOZEKI ICHIRO
IPC: H02M7/48
Filed: 1993-03-31
Abstract: PURPOSE:To reduce a harmonic component contained in an output current by a method wherein the turn ratio of a transformer is set in such a way that the quiescent period of a current which is input to a power-supply circuit from an AC power supply becomes short. CONSTITUTION:When a switching element (Tr) 3 is turned on, a voltage V1 is applied to a primary winding of a transformer T2, and the voltage V1 is transformed, by the transformer T2, into a secondary voltage V2 which is proportional to a turn ratio N2/N1. When the secondary voltage V2 is larger than an output voltage V0, a secondary current 10 which is proportional to their difference flows in a capacitor C2. When the Tr 3 is turned off, the secondary voltage V2 is not generated. However, the current I0 flows into the capacitor C2 by energy which has been stored in a choke coil L1. In this manner, an AC input current IIN does not flow in a circuit only in a section in which the secondary voltage V2 is larger than the output voltage V0, and a phase thetais generated. When the phase theta becomes large, a harmonic component contained in the input current IIN is increased. In order to suppress the component, the ratio N2/N1 is set in such a way that theta/2 is at 25 deg. or lower.

Title: Method for processing arrangement of logic element of semiconductor integrated circuit
Inventor: TOKUYAMA KOKI
IPC: H01L21/82
Filed: 1995-03-30
Abstract: PURPOSE: To obtain a logic element arrangement processing method by which the optimum wiring length can be decided from the operating speed of a logic circuit constituting a semiconductor integrated circuit. CONSTITUTION: Firstly, the dividing position of an arranging area is decided. Then a logic element having a connection to an element outside the area is extracted with respect to an arrangement logic element in the arranging area and the logic element in the area is classified from the dividing position of the arranging area and position of the element on the outside of the area. Thereafter, the arrangement of the logic element is found by arranging the logic element at a position which is nearer to the element outside the area against dividing line and dividing the arranging area. When the arranging area is divided into logic blocks of nearly the same sizes, the fluctuation of the wiring length of the network between the blocks can be suppressed to about the length of one side of the circumscribed rectangle of the blocks.  Therefore, the wiring length can be saved by the amount corresponding to one stage of buffers upon setting the variation of the drivability of the logic element.

IPC: B41J2/185
Filed: 1981-05-18
Abstract: PURPOSE:To stabilize the performance of an ink recovery pump by connecting the suction side of the pump to both a gutter for collecting unnecessary ink and an ink tank, thereby increasing the suction ink amount into a pump chamber with respect to the suction air amount. CONSTITUTION:The suction side of an ink recovery pump 2 is connected through a pipe 6 to both a gutter 1 and an ink tank 5. Thus, since an ink and air mixture is fed from the gutter 1 but only the ink is fed from the tank 5, the ink ratio in the pressure chamber of the pump 2 becomes high with the result that the performance of the pump 2 is stabilized. When the pump 2 and a supply pump 3 integrated, the performance of the pump 2 is stabilized. Accordingly, the performance of the pump 3 is stabilized, and the power of a common drive source for driving both the pumps can be reduced.

Abstract: PURPOSE:To improve the product quality and to extend the life of an end side wall longer by providing an Ni plating layer, Ni alloy plating layer and Cr plating layer in order in specified thickness on the inner face of a water cooling type end side wall. CONSTITUTION:The Ni plating layer 3 in 0.1-0.6mm thickness is formed as a 1st layer on the inner face of the end side wall 2 composed of a Cu or Cu alloy and the Ni alloy plating layer 4 in 0.1-0.2mm thickness is provided as a 2nd layer on the upper face thereof. The Cr plating layer 5 in 0.02-0.05mm thickness is formed as a 3rd layer on the upper face of the plating layer 4. In this case, the adhesion of the 1st layer 3 is improved because the Ni plating layer 3 of the 1st layer has less difference in the thermal expansion coefft. with the end side wall 2. Due to the Cr plating excellent in wear resistance, heat resistance and hardness being used on the 3rd layer 5 the damage of the end side wall 2 is reduced and the product quality is improved. The end side wall 2 is made in a longer life because the adhesion of the plating layers 3, 4, 5 is improved by the interposition of the 2nd layer 4.

Title: Memory device and control device
Inventor: MITSUCHI EI EIGUNA
IPC: G06F12/06
Filed: 1989-03-27
Abstract: PURPOSE: To make it possible to handle a large quantity of data supplied at a high speed in a short period by providing the device with one set of memory segments, one set of memory control units, a data demultiplexer and a device control module. CONSTITUTION: When a host processor supplies data words at a high speed to the memory device 10, the data multiplexer 30 directs the continuous memory words to the different memory segments 20 to 23. A decoder supplies special signals to the memory control units 50 to 53 relating to the memory segments 20 to 23 to which the data are directed. These memory control signals adjust the memory functions in the memory segments in coincidence with the data supply to these segments when these signals activate the control units and the memory control signals are generated. As a result, the 'overlapping' of the memory functions to be executed by the memory segments is made possible and since the temporary interleaving is made possible, the speed at which the memory device can process the data is increased.

Title: Elastic surface wave device
Inventor: YAMADA AKIRA
IPC: H03H9/25
Filed: 1984-04-16
Abstract: PURPOSE:To improve spurious characteristics by forming surface wave absorbers on an elastic surface wave propagation path by a screen printing method. CONSTITUTION:Input electrodes 2 and output inter-digital electrodes are formed on an LiNbO3 plate 1 as a piezoelectric body. The elastic surface wave absorbers 5 and 6 are formed of elastic surface acoustic wave absorber materials on the substrate by screen printing technique. Each absorber is formed having at least part of the incidence terminal slanted to an incidence direction of an elastic surface wave. The absorber materials are ''Hykit'' and ''Markem'' ink for the screen printing. The spurious characteristics are improved because the absorbers are formed to uniform thickness and width and unnecessary reflected waves are suppressed uniformly to the opening width of the inter-digital electrodes. Further, the absorbers are formed having the incidence terminal parts slanted to the incidence direction, so the elastic surface wave is scattered effectively at an incidence terminal part.

Title: Purging method residual coal
Inventor: ORIMOTO MANABU
IPC: B02C15/12
Filed: 1980-06-05
Abstract: PURPOSE: To shorten the time required for purging the residual coal in a pulverizer by a method wherein when the residual coal is purged by burning, the time for purging the coal the acknowledgement of extinction of the flame of the burning coal by a flame detector is determined in proportion to the load on the pulverizer at the time when the operation of the pulverizer is stopped.  
     CONSTITUTION: A certain amount of raw coal in a banker 1 is supplied on a rotary plate 7a of the pulverizer 4 and is purged by the relative motions of upper and lower pulverizing wheels 8 and 7 and pulverizing balls 10. In case the pulverizer 4 is restarted in a condition in which some of the pulverized coal remains therein, a blower 15 is operated first and the residual coal is purged by a drying mixture of cool air 13 and hot air 14. The purged coal is then transferred to a coal burner 21 through a powdered coal exhaust pipe 20 and is burned by use of an ignition torch or the like. In this case, the combustion of the residual coal is watched by the flame detector 22 and after the extinction of the burning fire, the coal is purged within the purge time determined in proportion to the load on the pulverizer at the time when the pulverizer ceases to operate. Thus, the purge time for the residual coal is minimized and the restarting of the pulverizer is made quickly.
