Title: Method of bleaching surfactant solution
Inventor: YURUGEN GURIYUTSUKE
IPC: C09K23/56
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for bleaching a surfactant soln. which can efficiently bleach an aq. surfactant soln. and can provide a very pale, odor-free product having excellent color stability under mild conditions by comprising treating a concentrated aq. surfactant soln. with hydrogen peroxide or the like under specified conditions.  
     SOLUTION: In bleaching a concentrated aq. soln. of a surfactant, such as an alkyl polyglycoside, having a pH value of 7 to 10, in the first stage, oxidation bleaching is carried out using hydrogen peroxide as a bleaching agent in the presence of a stabilizer using an inorg. magnesium compd. in an amt. of 50 to 10,000 ppm (based on the surfactant). After optional predecomposition of the peroxide using a transition metal (compd.) over a catalyst provided in the intermediate position, in the second stage, excess, unreacted bleaching agent and/or oxidizing secondary products produced therefrom are removed by the addition of an enzyme having catalytic activity, such as catalase, pref. in an amt. of 0.1 to 5,000 ppm to bleach a concentrated aq. surfactant soln.

Abstract: PURPOSE:To avoid any possibility of being incurred into a very dangerous state by constituting a steering shaft so as to be set to a fail-safe mode which restores it to a neutral position, in the case where travel of a spool valve is detected and it has moved abnormally. CONSTITUTION:A rear-wheel steering mechanism 171 is provided with a cylinder chamber 92 installed around a steering shaft 80 supported on a housing 12 shiftably in the axial direction, and a piston 84 partitioning off this cylinder chamber 92 into a first cylinder chamber 94 and a second cylinder chamber 95, and pressure oil for steering rear wheels is fed to either of the first cylinder chamber 94 or second cylinder chamber 95 by means of an axial movement of a spool valve 60 for a spool valve mechanism 148. In this case, there is provided a travel detecting means 69 which detects the extent of axial travel and generates a position signal, whereby the position signal is compared with a reference signal, and when the spool valve shows an abnormal movement, each pressure of both these cylinder chambers 94, 95 is equalized and thereby the steering shaft 80 is reset to the neutral position by a fail-safe mechanism 149.

Title: Obstacle detector for vehicle
Inventor: TAKAGI SEIWA
IPC: G01S7/48
Filed: 1992-09-03
Abstract: PURPOSE:To lengthen the detectable distance to an obstacle by arranging a semiconductor laser in a direction for facilitating transmission of laser beam through a front window shield. CONSTITUTION:A laser diode 60a is arranged while opposing to the lower edge region of a front window glass 10 inclining at an angle of theta=30 deg. for example, so that the active layer 61 of the laser beam having polarized waveform (p) emitted from the laser diode 60a transmits through the front window glass 10 and impinges on an obstacle without reflecting significantly on the front window glass 10. Similarly, laser beam reflected on the obstacle impinges on a photodetector while retaining the polarized waveform (p). This constitution maximizes the quantity of laser beam emitted from the laser diode 60a and transmitted through the front window glass 10 or the quantity of laser beam reflected on the obstacle and transmitted through the front window glass 10, thus extending the detectable distance of obstacle.
