Title: Light stabilization of cyanine dye
Inventor: NANBA NORIYOSHI
IPC: G11B7/249
Filed: 1990-04-20
Abstract: PURPOSE:To impart an excellent light resistance to a cyanine dye having a specified color cation by combining the color cation with a quencher anion, thus stabilizing the cyanine dye. CONSTITUTION:A cyanine dye having a color cation of formula l or II (wherein phiand psi are each a heterocyclic residue for forming a cyanine dye, provided that the case where both phi and psi are residues of indolenine rings which may have fused aromatic rings is excluded; and L is a polymethine bonding group for forming a cyanine dye) as a color part is prepared. By combining the color cation with a quencher anion, the cyanine dye is stabilized against light. Particular examples of the quencher anion include a compound of formula III (wherein M is Ni, Cu or the like; and R<1>-R<4> are each H, an alkyl or the like), and a compound of formula IV (wherein R<5>-R<8> are each an alkyl or an aryl).

Filed: 1980-07-30
Abstract: PURPOSE: To stabilize the brake pedal stroke in a captioned cylinder by connecting the first pressure chamber with a reservoir constantly via spiral grooves for increasing the pressure in the first pressure chamber on the basis of the viscosity resistance of the liquid passing through the spiral grooves when a brake pedal is operated.  
     CONSTITUTION: A master cylinder to be used in a hydrostatic brake device for a car is provided with the second and the third pressure chamber 11 and 13 connected to a wheel cylinder for generating a high pressure and a pressure chamber 10 of a large diameter. The first pressure chamber 10 is constantly connected with a reservoir via a compensation port consisting of spiral grooves 27a, and a nonreturn valve 21 to permit the suction of liquid from the reservoir 20 and a relief valve 22 to provide for the upper limit value of pressure are equipped at the first connecting port 1c. Since the pressure increase in the first pressure chamber 10 at the initial stage of a brake pedal operation is attained by the viscosity resistance of the liquid passing through spiral grooves 27a, an effective braking can be obtained by a stable brake pedal stroke without reference to the stepping speed of the brake pedal.

Title: Idling speed control device for engine
Inventor: INOUE AKIO
IPC: F02D41/16
Filed: 1987-04-28
Abstract: PURPOSE:To enable a smooth rotational frequency change free from a sharp decrease in the engine speed to be provided by diminishing the controlled variable for damping in the case where the difference between an actual engine speed and a desired engine speed is decreased to less than a prescribed value in a damping control subsequent to an intake increasing control. CONSTITUTION:A control unit 16 judges from various signals whether the operating range of an engine 1 falls within a starting zone, and then, if said range falls within the starting zone, it presets the initial value of a starting intake quantity correction value. And further, after starting, a prescribed period of time elapses until said range is out of the starting zone, it makes correction for an increase of the starting intake quantity through controlling an intake control valve 13 for adjusting the quantity of flow in a by-pass passage 12. After said range passes beyond the starting zone, it decreases the starting intake quantity correction value gradually. Hereupon, although the damping amplitude is set to be large in the comparatively initial stages, if the difference between an actual engine speed and a desired engine speed is decreased to less than a prescribed value, the damping amplitude is made smaller. Thereby, the feedback control cannot be adversely affected, and accordingly, a marked falling off in the engine speed can be eliminated.
