IPC: H04N5/073
Filed: 1988-06-20
Abstract: PURPOSE:To synthesize pictures by providing a synchronous switching means which selectively supplies the synchronizing signal of a second input video signal or that of a write video signal to a reading means. CONSTITUTION:When the synchronizing signal of a second input video signal Ai2 is supplied to a reading means 7 from a synchronous switching means 9, the read video signal from a memory device 1 is synchronized with the second input video signal Ai2. Therefore, two video signals synchronized with each other, namely, a read video signal Ao and the second video signal Ai2 are synthesized by a picture synthesizing means 10. When a first input video signal Ai1 is selected by a writing means 5, this signal Ai1 and the second input video signal Ai2 are synthesized; and when the second input video signal Ai2 is selected by the writing means 5, the second input video signal Ai2 is mutually synthesized.

Title: X-ray photograping device
Inventor: YAMAMOTO KAZUO
IPC: H05G1/34
Filed: 1980-10-28
Abstract: PURPOSE:To enable highly precise adjustment of the current of an X-ray tube to be applied in a wide voltage range by generating a heating cmpensatory function signal by use of a tube voltage signal, and operating the resistance network of a transistor by means of the former function signal for compensating the X-ray tube current. CONSTITUTION:Output proportional to the primary side voltage of a high voltage generator 3 is sent from an adder 36 of a tube voltage pre-indicating circuit 21, through an adder 25 to a function generator 26. As an output V0 of the generator 26 increases, the equivalent resistace of a transistor 30 increases, the output of a rectifier 31 is applied to the primary side of a coupling transformer 39 connected to a filament heating transformer 9 of an x-ray tube 4, and the primary side resistance of the transformer 9 increases. When the output V0 is small, the voltage determined according to a tube current setting device 6 and a resistance 5 is applied to the transformer 9, since the secondary side of the transformer 39 is short-circuited with a transistor 29 biased off and the transistor 30 biased on. As a result, the current of the X-ray tube 4 can be adjusted with high precision in a wide voltage range, and the device can be used for various kinds of X-ray tubes.

Abstract: PROBLEM TO BE SOLVED: To make a packaging material with a barrier layer usable in a high humidity atmosphere by forming the barrier layer containing an inorganic layerlike compound and a resin on one of the faces of a plastic film with a specific thickness and a humidity permeability below a specified level. SOLUTION: A barrier layer 2 and a printed layer 3 are laminated on a plastic film 1. In this case, the plastic film 1 to be used is a polypropylene film or the like with 5 g/m<2> or less moisture permeability at 20 μm thickness. In addition, the barrier layer 2 is formed of at least, an inorganic layerlike compound and a resin, and the inorganic layerlike compound to be used is montmorillonite or the like. The resin to be used is polyvinyl alcohol or the like. In this case, the barrier layer 2 is formed by applying a coating solution in about 2-4 divided parts, and the coating build-up is an amount to meet the drying capability of a drying oven for a printing part each time each of the divided parts is applied.  Thus it is possible to control the deterioration of the barrier properties to a minimum extent even in a high humidity atmosphere and ease the limitation of a use range and at the same time, manufacture the packaging material continuously and simultaneously with the formation of the printed layer 3.

Then when the heat roller 1 reaches set temperature T1 (180 deg.C), a heater control cirlcuit 15 controls electric power to a heater 2 so that the surface temperatures of both the rollers 1 and 3 rise. Then, when the surface temperature of the heat roller 1 attains to set temperature T1, the output of a comparator 7a is inverted from ''H'' to ''L'' to set a flip-flop 8, whose set output Q is supplied to one input terminal of an AND gate 21. The output of this AND gate 21 turns on a TR12 to turn on a ready lamp 13, displaying a copying enabled state.

IPC: G06F12/08
Filed: 1989-06-15
Abstract: PURPOSE:To improve the control performance in a buffer memory control system by starting the access to a buffer memory when the calculation is through with a lower rank address. CONSTITUTION:The addresses are divided into the higher and lower sides, and these divided addresses are added together by adders 3 and 4 and stored in an AHR 5 and an ALR 7 respectively. The produced carries are stored in a CR 6. In a buffer memory access cycle, a TLB 9, a cache tag 10, and the cache data 11 are read out addresses by A16 - 29 of the ALR 7. At the same time, the contents of the AHR 5 are added to the carry of the CR 6 via an I 8. Then the higher rank addresses A0 - 15 are compared with the addresses A0 - 15 read out of the tag 10 by the comparators 12 and 13. Then the TLB HIT and the TAG HIT are outputted by reference to the protection information P of the TLB, the tag 10 and a valid unit V of the TLB. The data read out of the data 11 is stored in a DAREG 14 and used for arithmetic as long as the TLB HIT and the TAG HIT are outputted. As a result, the control performance is improved in a buffer memory control system.

Filed: 1990-06-08
Abstract: PURPOSE:To improve durability and to maintain good electromagnetic conversion characteristics by carrying out a process of lubricant impregnation before the curing process in the production process including lubricant impregnation, punching into a disk form, and curing of the magnetic layer. CONSTITUTION:In the production process including lubricant impregnation, punching into a disk form, and curing of the magnetic layer, the magnetic layer is impregnated with a lubricant before curing process.

Then when cured in the next process, a proper amt. of the lubricant can be held in the crosslinked structure. By this method, durability of the medium can be improved and the obtd. disk type magnetic recording medium has high electromagnetic conversion characteristics.

Filed: 1987-06-17
Abstract: PURPOSE:To make an exterior-fitting component unnecessary and to reduce the number of external electrodes, by generating a signal being delayed by a constant time behind an input signal, and obtaining a two multiplied output by inputting both signals to an EX-OR (exclusive OR) circuit.

In other words, when the input signal is higher than a reference power source VA, the capacitor 2 performs constant- current discharge by a current source 12, and performs constant-current charge by a current source I1 when it is lower than the reference power source. Clipping is applied on a charging/discharging waveform centering a reference voltage VB symmetrically in an up-and-down direction by clipping circuits 3 and 4, and the waveform is delayed for the constant time by a waveform arranging circuit 5, and the two multiplied output can he obtained by inputting the waveform to the EX-OR circuit 6. In such a way, it is possible to reduce the number of the external electrodes (for the input signal) and to constitute a two multiplication circuit possible to be operated in a wide range of frequency in an integrated circuit.
