Patent JP-S6419634-A (JP)
Title: Sealed contact device
Inventor: INOUE HIROMICHI
IPC: H01H1/66
Filed: 1987-07-14
Abstract: PURPOSE:To hinder an arc from running and suppress contamination by arc by arranging a stationary contact supporting member in the opposite direction to movement of the arc. CONSTITUTION:When pressing on a movable shaft 31 goes out, the shaft 31 is displaced in the opposite direction to the arrow a by a tensile force generated in bellows 34, and a movable contact 32 goes apart from a stationary contact 27 to break between this and the movable contact 31. When the direction of magnetic field B and the direction of current I flowing between contacts 27 and 32 are specified as in the attached illustration, the arc A generated when the contacts are broken, receives a force in the direction of arrow F according to Fleming's left hand law and moves toward the airtight space on the opposire side to where the stationary contact 27 and one end 26b of stationary shaft are fixed. As shown by the reference mark e, the arc at the same time runs so as to cover one of the surfaces of the stationary contact 27 and movable contact 31, i.e. the surface oriented in the direction the arc A is moving, and does not move to the side where the oppositely situated stationary shaft 26 is arranged. Thus contamination is suppressed.

Title: Lens for optical disk
Inventor: SUGIYAMA TAKAHIRO
IPC: G02B13/00
Filed: 1985-08-09
Abstract: PURPOSE:To especially correct the chromatic aberration satisfactorily by being a three-group four-sheet constituting lens, and specializing the relation of the focal length of all systems and the first group lens, the Abbe's number of the positive lens and the negative lens in the first lens and the curvature radius of the sticking surface of the first group lens. CONSTITUTION:The lens is a three-group four-pieces constituting lens and satisfies formulas 1-3. Here, f is the synthesized focal length of total lens system, f1 is the focal length of the first group lens, nu+ and nu- are Abbe's num ber of the positive lens and the negative lens in the first group lens and r2 is the curvature radius of the sticking surface of the first group lens. When f1 is smaller than the lower limit, the negative spherical aberration quantity to occur at the first group lens comes to be too large, and reversely, when it is larger than the upper limit, the burden of the third group lens and the correction of the spherical aberration comes to be hard. When ¦nu+-nu-¦ is larger than the upper limit, the action to the correction of the chromic aberration is too small, and when ¦r2¦ is large than the upper limit, the achromatic action by the positive lens and the negative lens in the first group lens comes to be small and the correction of the chromatic aberration is short.

Title: Power control circuit for high frequency power amplifier
Inventor: KOYAMA MASAHARU
IPC: H03F3/60
Filed: 1987-07-14
Abstract: PURPOSE:To reduce the power consumption for power control and to reduce the cost of the titled circuit through the miniaturization and less capacity by controlling the current flowing to a rectifier element connected in series with an input terminal of an amplifier transistor (TR) of a high frequency power amplifier. CONSTITUTION:The high frequency rectifier element 6 is connected in series with the input of a base of an amplification TR 7 and a control TR 7 controls the current flowing to the element 6. With the TR 7 turned on, a required current flows to the element 6 and since the element 6 is in the ON state, the input power is fed to the TR 1 without almost any loss by the operation of an input matching circuit 4 and the required output power is obtained. In varying the voltage or the current fed to the control terminal of the TR 7, the internal resistance of the TR 7 is changed continuously and the current flowing to the element 6 is changed and since the element 6 acts like a variable attenuator, the output power is changed continuously. That is, since less power is enough to turn on the element 6, the power consumption for power control is reduced and low-cost and high accuracy of the circuit are attained.

Abstract: PURPOSE:To judge easily even a failure condition with minor reflection upon a change in an air-fuel ratio itself such as clogging of a fuel injection valve in a particular cylinder by judging a failure in the fuel system of a part of cylinders based on the turbulence of an outputted waveform from an air-fuel ratio sensor detected by a waveform detection means which detects the waveform of an outputted signal from the air-fuel ratio sensor. CONSTITUTION:Upstream of a three way catalytic converter 11 in an exhaust tube 10, an O2 sensor 16 is provided, for detecting oxygen concentration (A/F) in the exhaust gas which flows in an exhaust passage 10a. An engine controller (ECU) 9 compares the output of the O2 sensor 16 with a fixed reference voltage value corresponding to a stoichiometric air-fuel ratio lambda=1, and increases or decreases supplied fuel amount for controlling an actual air-fuel ratio so as to keep it around the stoichiometric air-fuel ratio. In the ECU9, an engine data signal necessary for control is stored. Moreover, a change cycle which crosses the slice level of an outputted signal waveform from O2 sensor 16 is stored, and is compared with the change cycle of a reference value which indicates an abnormal condition so as to judge a failure.
