Abstract: PURPOSE:To permit the confirmation of recording by visual observation of transferred recordings of each color in order by a method in which the tip of an image receiving paper is pressingly held and an optical opening is provided on a casing to enable the periphery of the drum to be visualized. CONSTITUTION:During the period of waiting state or recording completed state, a paper holder 42 is separated from a notch 45 against a spring 44 with the contact of an arm 46. When an image receiving paper 52 is put between the holder 42 and the notch 45, the arm 46 is turned, the paper 52 is held by the spring 44, and each color ink of a transfer paper 35 is orderly recorded by a thermal head 31 with rotation of the drum 40. In this case, the paper 52 wound around the drum 40, cyanine C, yellow Y and Magenta M are orderly observed from an opening window 54 to confirm the condition of recording. Since the window 54 is present nearly above the notch 45, the sufficient insertion of the paper 52 can be visually confirmed and the mal-holding of the paper 52 by the holder 42 can be prevented.

IPC: B29C48/45
Filed: 1985-04-15
Abstract: PURPOSE:To constitute continuous manufacturing of a high-viscosity composite material made of synthetic resin, by a method wherein raw material resin is pushed forward through a rotation of a screw, the screw is made to move backward through pressing along with an action that a cave is filled with molten resin and the molten resin is pushed out by making the screw move forward after the cave has been filled with the molten resin. CONSTITUTION:A screw 4 is made to rotate while raw material resin 1 is being supplied to an extruder 2 through a hopper 9. The raw material resin 1 is filled out the inside of a cave 3 in front of the screw 4 in turn by turning the same into molten resin while the same is being agitated. As pressing with a hydraulic instrument 8 is kept released, the screw 4 is moved backward in turn. The inside of a die 6 is filled with molten resin 5 also and the resin 14 made by the previous process is still in existence within a cooling and sizing sleeve 7. After a predetermined quantity of the molten resin 5 has filled out the inside of the cave 3, the molten resin 5 is pushed out by making the screw 4 move forward by the hydraulic instrument 8. On this occasion, the remaining resin 14 in the cooling and sizing sleeve 7 is extruded by the molten resin.

Abstract: PURPOSE:To precisely detect the thrust of the grinding wheel without disturbing the  smooth operation of the grinding wheel at all by a method wherein four strain gauge  are provided between a rocking body and a supporting frame body and one strain  gauge is also provided between the supporting frame body and a head part frame body. CONSTITUTION:When a large thrust parallel to the rocking body 5 is applied to the  grinding wheel 1, the screening plate 22 of the strain gauge 19 is slided together with  the supporting frame body 7 so as to screen a predetermined number of light sources  20, 20,... with the screening plate 22 from a photocell 21. Consequently, when the thrust larger than the predetermined value is detected by the number of the light sources 20  screened with the screening plate 22, the grinding wheel 1 is retreated. On the other  hand, when a large thrust normal to the rocking body 5 is applied to the grinding  wheel 1, the rocking body 5 is caused to rock and the screening plates 22 and 22 of  the strain gauges 15 and 17 or 16 and 18 are slided toward the same direction of the  rocking of the rocking body 5. When the thrust larger than the predetermined value is detected by the number of the light sources 20, 20,... screened with the screening plates 22 and 22 slided as just mentioned above, the grinding wheel 1 is retreated normally to the rocking body 5.

Title: Blocking releasing method for powder transport pipe
Inventor: NAKA KOUSON
IPC: B65G53/52
Filed: 1981-05-22
Abstract: PURPOSE:To release blocking of a transport pipe by dividing the transport pipe into plural sections by valves, each of which compressed air is introduced to and by raising the pressure of an obstructed section and then opening the valve on discharge side to eject obstruction together with the compressed air. CONSTITUTION:In a high-pressure transport apparatus, a transport pipe 10 extending from a blow tank 11 to a tank 13 is divided into n-sections S1-Sn by valves V0-Vn. Compressed air is introduced from a compressor 20 and a pressure accumulator 18 through valves W1, W2 to each section. When blocking is caused in the pipe 10, all the valves are closed. When compressed air is introduced to the section S1 first and the section becomes high-pressure, the valve V0 is opened to discharge air impulsively and remove obstruction. Subsequently the same operation is performed on the section S2, and the operation is consequently continued, which can release blocking in the whole pipe 10.

Abstract: PURPOSE:To shorten a copying time, and simultaneously, to reduce the influence due to copying by re-storing data from a main system saving magnetic device to a spare system data storage part, using only the data updated from a host device as copying data from a main system. CONSTITUTION:When a main system control part 13 receives the write-in start address of a write-in command from the host device, it stores '1' in a bit corresponding to a cylinder number and a track number on a main system control memory 17. At the time of copying the contents of a main system data storage part 11 to the spare system data storage part 12, a spare system saving magnetic disk control part 20 reads the data stored in the main system saving magnetic disk device 15, and re-stores it in the spare system data storage part 12, afterwards, the main system control part 13 reads the contents of the main system control memory 17 bit by bit, and decodes the cylinder number and the track number of the main system data storage part 11, and copies only the data of a track having been updated on the main system data storage part 11 to the spare system data storage part 12 as the copying data. Thus, a time required for copying the data can be shortened, and in addition, the influence of input/output operation by data copying can be reduced.
