Title: Thermal stencil paper
Inventor: HAYASHI KAZUJI
IPC: B41N1/24
Filed: 1985-01-18
Abstract: PURPOSE:To prevent electrostatic charging and enable a printing operation to be conducted without trouble, by adding an antistaticizer consisting of a phosphoric acid ester compound to a releasable layer, in a thermal stencil paper provided with a releasable layer for preventing welding of the stencil paper to an original. CONSTITUTION:The releasable layer 17 is provided by applying fine powders, sodium stearate or the like. Accordingly, a thermoplastic synthetic resin film 2 is prevented from being welded to an original 9 in the vicinity of an opening part 13 of the film at the time of stencil making, and the original 9 can be easily released from the stencil thus made. The antistaticizer 18 consisting of one or a mixture of phosphoric acid ester compounds is mixed with a releasing agent, and the mixture is applied to the surface of the film 2. The antistaticizer prevents electrostatic charges from being generated on the film 2 when the original 9 is released from the thermal stencil sheet 1, and prevents electrostatic charges from being generated on the film 2 due to contact with a printing paper 16 at the time of printing.

Title: Image information generating device
Inventor: ISHISASHI TAKESHI
IPC: G11B20/10
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a device which can composite image information obtained form plural types of sources and can record the image information on a single recording medium by compositing the frame information outputted from those sources after superposing these frame information on each other in the sequence of their input. SOLUTION: When an interrupt signal generator 25 detects a blanking signal, the generator 25 outputs an interrupt signal to make a video signal switch 26 input the video signal that is outputting the blanking signal. The switch 26 fetches and stores the video signals equivalent to a single frame. In other words, the switch 26 has a function to store the video signals equivalent to a single frame which are received from plural sources that are connected to the switch 26. When the storage of video signals equivalent to a single frame is completed, the switch signal outputted from an external command part 27 is written into part, corresponding to the blanking of the frame information and then outputted together with the frame information. As a result, two types of images sent from two video decks, for example, are alternately composted with each other every two frames.

Title: Cache memory
Inventor: KUMAZAWA YUKIO
IPC: G06F12/08
Filed: 1989-01-18
Abstract: PURPOSE:To improve a hit rate in a cache memory by executing processing using data with small using frequency through a by-pass circuit, and in the case of executing processing using data with large using frequency, inputting changed data to a data memory circuit and updating the tag contents of a tag memory circuit. CONSTITUTION:An interruption handler 24 decides whether data are to be frequently used for storing them in the data memory circuit 22 or not, and when the data storage is available, allows the storage of the data in the circuit 22. When the data storage is not available, the data storage is not allowed. At the time of allowance, data are supplied from the circuit 22 and data which are not stored in the circuit 22 are read out from a main memory 3 and stored in the circuit 22 to supply them. When the data storage is not allowed, a processor 1 accesses the main memory 3 through the by-pass circuit 23 and also accesses I/O devices 4, 5 requesting interruption. Consequently, only the data having large using frequency is stored in the data memory circuit 22 and the hit rate is improved.

Title: Explosion-proof cathode-ray tube
Inventor: KUNIBE TAKEMITSU
IPC: H01J29/87
Filed: 1982-01-25
Abstract: PURPOSE:To omit the lap fusion between a metallic fastening band and a metallic shield band, which is used for shielding X-rays, by unifying the fastening band and the shield band together, and shaping the unified body into a frame- like member without forming any joint part between these bands. CONSTITUTION:The whole of a metallic fastening band 8 has a tapered part 9 in order to keep it away from the fused part 1a of a picture tube 1, and is unified with a metallic shield band 10 by pressing. Due to such a unifying press, the fastening belt 8 has no cut surfaces, and needs not to undergo any fusion. Since the fastening band 8 and the shield band 10 are unified together by means of the tapered part 9, there is no need to carry out fusion, and the work cost can be widely reduced. The fastening band 8, since it applies pressure homogeneously to the entire circumference of the picture tube 1, exhibits an excellent explosion-preventing effect, and improve the work efficiency. In addition, since the shield band 10 gives an effect of preventing the leakage of X-rays, such a cathode-ray tube is more excellent than the conventional one of a split type in terms of the appearance, work efficiency, the work cost and the explosion- preventing effect.

Title: Control of current for super conductive coil
Inventor: HAMASHIMA KOUTAROU
IPC: H01F6/00
Filed: 1981-01-27
Abstract: PURPOSE:To contrive reduction of the sectional area and the weight of the subject super conductive coil by a method wherein a current is supplied to the super conductive coil up to the prescribed current value maintaining a super conductive state, then the super conductive coil is maintained at a stabilized super conductive state by changing the current from the prescribed current value to zero point or to a value slightly inverted. CONSTITUTION:As the change of magnetic flux alone is necessary for generation of plasma, the change of current from time T0 to time T1 will be sufficient for this purpose. To be more precise, the current is brought up to the prescribed value by slowly increasing it from time T2 until time T0 is reached. And the necessary change of magnetic flux is generated from time T0. When the current is controlled as above, abundant bubbles are generated accompanying a sudden current variation between T0 and T1, and the generated amount of heat is very small when the current is at zero or in a state close to zero, even when the removal of heat is deteriorated. Also, when the above is changed to a normal conductive state, it is immediately recovered to the stabilized super conductive condition.
