Title: Ink jet recorder
Inventor: KAWAMURA KIICHI
IPC: B41J2/19
Filed: 1978-05-15
Abstract: PURPOSE:To prevent the air bubbles produced in an ink tank from entering an ink jet head by providing a branch pipe to an ink supply tube and giving ultrasonic vibrations to the neighborhood of the branch pipe. CONSTITUTION:A branch pipe 8 is made upward, with its mounth open to the atmosphere, and is formed to such a size and shape that ink slightly rises owing to capillarity. Thereupon, if it is assumed that an air bubble is produced in an ink tank 6 and this air bubble begins to move toward a head 5 by passing through an ink supply pipe 7 owing to the flow of the ink, then the air bubble moves and ascends toward the branch pipe 8 and escapes to the atmosphere because the branch pipe 8 is provided on the way of the ink supply pipe 7 and its neighborhood is being excited by an ultrasonic oscillator 9. Hence, the movement of the air bubble to the sebsequent parts is prevented, actuating regularly head 5.

IPC: F02K3/075
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To increase fluctuation of bypass ratios of a variable cycle engine which is a propagation system for a supersonic transport aircraft. SOLUTION: This engine has a bleed air passage P1 connecting an intermediate stage of a compressor to high/low pressure turbines, and bleed air valves V1, V1' arranged on its inlet and outlet. A bleed air passage P2 is arranged for connecting the inlet of the low pressure turbine to an exhaust duct, while a bleed air valve V2 is arranged on its inlet. A front variable injector FVABI is arranged on the inlet of a bypass passage, while a rear variable injector RVABI is arranged on the outlet. The bleed air passage P1 is closed and the bleed air passage P2 is opened in supersonic cruising. The bleed air passage P1 is opened and the bleed air passage P2 is closed in taking off. It is thus possible to differentiate flow passage of the high pressure turbine from that of the low pressure turbine, and change the rotation matching of the high pressure system and the low pressure system.  In addition, specific impulse is increased in supersonic cruising, while exhaust speed is reduced in taking off.

Title: Heater
Inventor: NAGATO YOSHIAKI
IPC: H05B3/00
Filed: 1994-03-29
Abstract: PURPOSE:To allow proper cracking to be generated in an insulative base board and reduce the man-hours by providing two or more conductor through holes in such an arrangement as crossing the acting direction of a tensile stress generated in the base board. CONSTITUTION:When the drive control goes out of order and the temp. of a band-shaped heat emitting body 3 has overrisen abruptly while the heat emitting body 3 is operated by a heat emission control circuit C, a tensile stress extending in the longitudinal direction of a base board 1 resulting from difference in the coefficient of thermal expansion between the the heat emitting body 3 and base board 1. The tensile stress is likely concentrated on conductor through holes 7 provided in the overlapping part A of two current feed patterns 4, 6, Because the orientation direction L1 of the holes 7 is across the virtual line Lx which is identical to the main thermal expansion direction of the heat emitting body 3, the base board 1 cracks with the direction L1 as boundary resulting from the tensile stress acting in the Lx direction. This divides at least the electricity conducting path leading from the other end of the body 3 to a back electrode 5, and AC current will no more be fed to the body 3 from the control circuit C.

Title: Control system for cooling/heating devices
Inventor: IWASA NOBUHIRO
IPC: F24F11/00
Filed: 1983-04-04
Abstract: PURPOSE:To curtail the waste of electric power by a method wherein the operations of the cooling/heating devices are interrupted at a predetermined time interval by turning switches in sequence so that the temperature of the region to be cooled or heated does not scatter irregularly. CONSTITUTION:When the power supplied to the cooling/heating devices exceeds a predetermined value P, it is detected by a power detecting circuit 4. Therefore, a control circuit 2 interrupts selectively one or more than one of the switches S1-Sn so that the cooling/heating device An is selectively operated through the switch, for example, the switch Sn, in its ON condition. Then at time t2, most of the devices A1-An are operated again simultaneously and when there is a possibility that the power supplied to the devices exceeds the value P, the control circuit 2 keeps the switch other than the switches S1 and S2 which have once been interrupted, for example, the switch Sn, for a predetermined period of time through a timing circuit 5. Thus, by changing in sequence the switches S1-Sn to be interrupted, it is possible to keep the temperature in the room uniform throughout the whole space.
