Title: Deflecting coil for image pickup tube
Inventor: SAKAI HIDEYUKI
IPC: H01J29/76
Filed: 1983-09-19
Abstract: PURPOSE:To prevent a deflecting magnetic field from giving ill influence on the foucsing effect of a main lens by installing a cylinder made of a high permeability material coaxially with an image pickup tube and in an area of a coil bobbin surrounding the electron-beam-focusing part of the image pickup tube and located inside the winding of a deflecting coil. CONSTITUTION:A cylinder 18 made of a high permeability material is installed in an area of a deflecting coil bobbin 15a surrounding an electron-beam-focusing part. As a result, a magnetic field produced by a deflecting coil in an image pickup tube does not encroach upon its main lens and a superior picture quality is obtained despite a shortended total length of the image pickup tube. A slight increase of deflecting electric power is unavodably caused by installing such a shielding cylinder made of a high permeability material. However, it is possible to almost eliminate the difference in the amount of electric power practically by moving the peak of a deflecting magnetic field a little forward by slightly decreasing the total length of the coil.

Title: Recharge preventive device of secondary battery charged full and battery and its charger
Inventor: SHIINO SHIGEKI
IPC: H02J7/10
Filed: 1990-06-28
Abstract: PURPOSE:To prevent the recharge of a secondary battery charged full by constituting it such that the quick charge condition of the secondary battery is not kept when the terminal voltage of a capacitor is higher than specified voltage. CONSTITUTION:After a battery back is mounted on a charger, a switch 9 is turned on to apply H voltage to an AND gate 26, and also, when the terminal voltage of a capacitor 15 is lower than the reference voltage of a terminal 29, H voltage is applied to the AND gate 26 from a comparator 28, so H voltage is applied on an AND gate 22. Moreover, for a - V detection circuit 23, if the terminal voltage of a battery 13 has not dropped, H output is applied to the AND gate 22, and a switch 21 is turned on, and it is charged quickly. And if one tries to charge the battery already charged full, since the terminal voltage of a capacitor 15 is battery voltage plus Zener diode voltage, the voltage above the reference voltage is applied to the comparator 28, and the output becomes L, so the switch 21 cannot be turned on, and the recharge can be prevented.

Filed: 1991-07-11
Abstract: PURPOSE:To reduce the wear or a mechanism section so as to improve the mechanical reliability of the electric operating device of a circuit breaker by moving a handle at an ordinary time only to its on-position and its off-position, and being able to move the handle to its reset position only when the circuit breaker is reset after tripped. CONSTITUTION:When remote on or off-switch 3 or 4 is operated, a drive section 12 drives an operating section 11 to push a handle 8 to its on or off-position so that the detecting action of a position detector switch 5 or 6 may stop the operation of the drive section 12 so as to carry out a remote operation. When the switch 4 is operated, the handle 8 is continuously pushed until it reaches its reset position, so that the detecting action of a position detector switch 7 may stop the operation of the drive section 12 since an alarm switch 9 makes a changeover connection to open a circuit on the switch 6 when a circuit breaker 1 is tripped. The switch 3 is subsequently operated to move the handle 8 to its on-position so that a circuit having caused an accident whereby the circuit breaker is tripped can be closed again after it is recovered from its accident.

Title: Air-fuel ratio controlling device for engine
Inventor: SUMITANI JIROU
IPC: F02D41/00
Filed: 1983-09-16
Abstract: PURPOSE:To judge the offset condition of air-fuel ratio with high responsive property in the running region having rich intake air amount while judging accurately same also in the running region having small intake air amount by setting the set time on an abnormality detecting means variably such that the smaller the intake air amount is, the longer the set time is. CONSTITUTION:A series of set time tm which are set such that the lower the rotational frequency of an engine and the intake negative pressure are and the smaller the intake air amount is the longer the set time is, are beforehand stored in a controller 19. The set time tm corresponding to the rotational frequency of the engine and the intake negative pressure is read out of the set time data to vary the set time tm such that the smaller the intake air amount is, the longer the set time is. Thus, in the engine running region having large intake air amount, an air-fuel ratio sensor 17 has high temperature as exhaust temperature rises to improve the responsive property of air-fuel-ratio feedback control. When the intake air amount is small, the set time tm becomes long to judge the deviation of the air-fuel ratio sensor 17 accurately without malfunction.
