Title: Ink pressurizing mechanism in ink jet printer
Inventor: ONO TAIICHI
IPC: B41J2/045
Filed: 1991-09-09
Abstract: PURPOSE:To enhance the selectability of ink, prevent clogging of nozzles, and obtain a high ink pressure by a method wherein a positive and negative pressure source is provided on a primary side using a diaphragm pump, and a diaphragm film and other part of the pump on the secondary side to come into contact with ink are made of materials which do not react with the ink. CONSTITUTION:In a diaphragm pump body 1, a diaphragm film made of vitor rubber is provided. On the secondary side, a check valve 2 is connected to nozzles, and a check valve 2a is connected to an ink tank 6. On the primary side, a solenoid valve 3 is disposed on a pressurizing side, and a solenoid valve 3a is on a sucking side. The output of a pump 4 in use, such as a vane pump, is approximately 20-25kgf/cm<2>. A vacuum pump 5 keeps a container containing ethylene glycol 8 under a pressure of approximately 400-700mmHg. By alternately opening and closing the solenoid valves 3, 3a, the diaphragm film is moved to repeat the suction and delivery of ink 7. The pump body 1 and the diaphragm film are made of materials which do not react with the ink, thus never crystallizing the ink.

Title: Air-flow direction changing device
Inventor: SAKURAI SEIICHI
IPC: F24F13/15
Filed: 1986-09-26
Abstract: PURPOSE:To extend the reach of air-flow and prevent short circuit by causing an opposing pair of air outlet louvers among the louvers on four sides to synchronously opened and closed automatically, while the other pair of opposing louvers is automatically closed and opened oppositely to the former pair of louvers. CONSTITUTION:When a projection 14 is situated at position A, a wire 16a is pushed to fully open outlet louvers 11a, and a wire 16b is conversely pulled to fully close outlet louvers 11b. When a louver actuating motor 12 is operated, a cam 13 is rotated clockwise, and the projection 14, too, goes into a circular motion of A B A. When the projection comes at position B, the wire 16a is pulled oppositely to what described above to fully close the outlet louvers 11a. As the air direction at the time when the louvers 11a are fully opened is directly downward, the low density air for room heating can be blown to the floor at a high rate, and, by sucking air from a space below the fully closed louvers 11b, short circuit can be prevented.

IPC: H01F6/06
Filed: 1987-09-12
Abstract: PURPOSE:To obtain a superconducting coil, in which a superconductor material is not required to be formed into a wire shape, by alternately laminating films comprising a composite oxide superconductive material, in each of which a part is cut, and intermediate films, in each of which a cut part is formed, on the upper surface of a ring shaped substrate. CONSTITUTION:A film 2, comprising a composite superconductive material including CuxOy, in which a part is cut, is formed on the upper surface of a ring shaped substrate 1. An intermediate film 3, in which a part is cut, is formed on the upper surface of the film 2. Another film 2 comprising the same material as said film 2, in which a part is cut, is formed on the upper surface of the intermediate film 3. Both films 2 and 2 are electrically conducted through a connecting part 3A. Thus, the films 2 and the intermediate films 3 are alternately laminated by a plurality of stages. For example, the substrate 1 comprising Al2O3 is set in a vacuum evaporation apparatus. A masking member is used. Laser light is alternately projected on an evaporating source comprising Y1Bz2 Cu3O7-y and an evaporating source for the intermediate film comprising Al2O3. Thus the films of the superconductive material and the intermediate films are alternately laminated.

Title: Direct coupling clutch control device for automatic transmission
Inventor: TAKADA MITSURU
IPC: F16H61/14
Filed: 1989-09-05
Abstract: PURPOSE:To prevent the occurrence of busy shift by a method wherein even when an engine output demand amount is increased after switching to a direct coupling clutch engaging state, while the degree of satisfaction of a membership function is low, a computing result of a control rule reduces possibility of disengagement of a direct coupling clutch. CONSTITUTION:When a direct coupling clutch CL of a torque converter 10 is switched from a disengaging state to an engaging state, a control device 14 stores an engine output demand amount detected by a throttle opening sensor 36. Even when a following engine output demand is increased, while the degree of satisfaction of the membership function of a transmission mechanism 12 in relation to the increase is low, the computing result of a control rule produced by a computing means 32 lowers possibility of disengagement of the direct coupling clutch CL. Thus, disengagement of the direct coupling clutch is difficult to permit. disengagement of the direct coupling clutch against the will of a driver is prevented, and as a result, the occurrence of busy shift is also prevented.

Filed: 1987-09-14
Abstract: PURPOSE:To facilitate connecting operation by allowing a catching member to intrude into part of the outer peripheral surface of an optical fiber cable standing in a tubular passage when inserted into a branch passage from an opening and thus stopping lengthwise movement. CONSTITUTION:The optical fiber cable 26 is machined to that its end surface 35 appears flatly, and its end part is inserted lengthwise into a tubular passage 27. While the end surface 25 of the optical fiber cable 26 and a light transmission and reception surface 21 are held in an abutting state, the catching member 29 is inserted into the branch passage 33 and reaches a position shown by a broken line, where leg parts 30 and 31 of the catching member 29 protrude in the tubular passage 27. The leg parts 30 and 31 of the catching member 29 intrude into part of the outer peripheral surface of the coating 36 of the optical fiber cable 26. The catching member 29 can not move lengthwise in the tubular passage 27 so the lengthwise movement of the optical fiber cable 26 is stopped. Consequently, the connecting operation is facilitated.
