Title: Operating method for vertical shaft pump
Inventor: SUZUKI NOBUHIRO
IPC: F04D15/00
Filed: 1993-03-12
Abstract: PURPOSE:To discharge stagnant water in a pump provided upward from an impeller with a proper timing, in non drain operating condition caused by reduction of a water level generated by a previous standby type pump. CONSTITUTION:An intake water level is reduced by continuance of drain operation, and operating condition of a pump 1 becomes non drain operation from drain operation, so that the load of a diesel engine 15 is reduced. And condition in which an exhaust temperature is reduced is detected by an exhaust temperature detecting sensor 16, and its condition is inputted into a control means 17. In the control means 17, non drain operating condition of a pump whose exhaust temperature is lower than a reference value is judged, and an opening signal is outputted into an opening/closing device 14 so as to open a branch pipe 13.

Title: Secondary air supplying device for internal-combustion engine
Inventor: KOSUDA TOORU
IPC: F01N3/34
Filed: 1982-04-01
Abstract: PURPOSE:To change a pressure fluctuation in the downstream chamber of a reed valve into the same in a positive pressure only in order to prevent the reverse flow in the chamber and avoid the damage by a fire of a reed type non-return valve by a method wherein a secondary air pipeline is branched and a secondary air introducing valve is provided in one of the branched pipes while the other of them is closed at the end thereof. CONSTITUTION:Pressure waves, propagated from an exhaust port through a secondary air pipe 17, are propagated into a branched pipe 21 communicating with the reed valve downstream chamber 9 through the branched pipe 18 and, at the same time, are propagated into the branched pipe 19 whose end 20 is closed. The pressure waves, propagated into the branched pipe 19 are reflected by the end 20 and returned again into the branched part 18, however, a time phase for reciprocating through the branched pipe 19 is delayed with respect to the same of the pressure waves propagating through the branched pipe 21 directly. As a result, the interference of the pressure waves in the high revolution zone of an engine becomes big, the negative pressure portion of the pulsation of exhaust gas is absorbed by the positive pressure portion of reflecting waves, and consequently, the pressure fluctuation in the reed valve downstream chamber 9 is changed into the fluctuation only in the positive pressure portion substantially.

Title: Ink jet recorder
Inventor: SATOU TSUTOMU
IPC: B41J2/17
Filed: 1980-04-22
Abstract: PURPOSE:To provide an ink jet recorder which uses two inks of different colors by a method wherein when the ink of one color is used up, the printing is continued by using the ink of the other color and a printing signal for the used-up ink can be used for the printing with the other ink. CONSTITUTION:For instance, when the printing signals for black ink and red ink are inputted at terminals TB, TR respectively, and if a red-ink float switch SR is turned ON to detect the absence of the red ink while a black-ink float switch SB is OFF to detect the presence of the black ink, the output of an inverter IV6 is reduced to a low level so that an AND gate G6 does not feed the red-ink printing signal to a red-ink printing section. However, an input to an AND gate G2 is raised to a high level so that the printing signal inputted at the terminal TR is fed to an OR gate G4 through the gate G2. In addition, the black-ink printing signal inputted at the terminal TB is also fed to the OR gate G4 through an AND gate G3 because the output from an inverter IV5 is at a high level, so that the black-ink printing signal is fed to a black-ink printing section together with the above red-ink printing signal.

IPC: H04H20/10
Filed: 1987-03-06
Abstract: PURPOSE:To temporarily broadcast a voice data at any time as necessary by providing a temporary voice storage section and a setting switch. CONSTITUTION:A desired temporary voice data is stored in a temporary voice storage section 180 and a temporary voice reproduction setting switch 403 is thrown to the position of reproduction as necessary and a temporary voice data read from the a temporary voice storage section 180 is added to the normal guide broadcast and then broadcasted.

IPC: H02K17/30
Filed: 1984-03-22
Abstract: PURPOSE:To obtain preferably rated operating characteristics with a low starting current by approaching a magnetic leakage member to a rotor core at a low temperature time and separating them at a high temperature time by a shape memorizing member. CONSTITUTION:A squirrel-cage winding 4 made of a conductor rod 2 and an end ring 2 is cast in a rotor core 1, and engaged with a rotational shaft 5. Disc-shaped portions 6 made of a magnetic material are opposed through a gap to the side of the ring 3, and a magnetic leakage member 8 is disposed oppositely to a cylindrical portion 7 at the outer peripheral side. In this case, the portion 6 is interposed between the first spring 9 manufactured of a shape memorizing alloy which elongates at a high temperature time and a shape memorizing member 11 made of the second spring 10 formed of a shape memorizing alloy which contracts at a high temperature time. Thus, the member 8 approaches the core 1 at a low temperature starting time, and contributes as a magnetic path of a leakage magnetic flux. Thus, it can be started by a low starting current. The member 8 is separated from the core 1 at a high temperature time in operation, thereby enabling the original rated operation.
