Title: Method and device for measuring electrochemical active component in process flow
Inventor: ORIBAA EMU JII NIYUUMAN
IPC: C25C1/16
Filed: 1987-09-11
Abstract: A method and apparatus for determining electrochemically active components in a process stream is disclosed. The method comprises the steps of providing a sample in which the components are contained, and depositing the components onto a working electrode, altering the environment of the working electrode so that it is immersed in a supporting electrolyte by effecting a matrix exchange and stripping the deposit electrochemically active components from the working electrode into the supporting electrode. A method and apparatus utilize a measurement cell which comprises a vessel (10) for containing the supporting electrolyte and a mercury electrode (150). A flow injector (16) is used to inject a flow with the sample electrolyte into the vessel so that the sample electrolyte surrounds the mercury drop electrode and then sinks away from the mercury drop electrode (150) to the bottom of the vessel where it is removed via an outlet (20) to thereby leave the mercury electrode (150) immersed in supporting electrolyte. The deposited impurities are stripped from the supporting electrolyte using variable time domain transient electrochemical stripping voltammetry. The sequence of steps including the deposition of the impurities from an injected flow of electrolyte sample are repeated under microprocessor control (50).

Title: Oil pressure control device for automatic speed change gear for vehicle
Inventor: TAKADA MITSURU
IPC: F16H3/44
Filed: 1988-09-12
Abstract: PURPOSE:To set the engaging speed of a first clutch to a proper value by providing a control valve which is actuated according to the output state of a prime mover and controls a speed at which an oil pressure is fed to the oil chamber of a first input clutch. CONSTITUTION:During 4-3 power-ON down shift, a spool valve 302 of a C1 control valve 300 is situated in a rising position. In this case, a relatively high first accumulator oil pressure is exerted on a control port 338. In this case, a spool valve 332 of a control valve 330 is located in a lowering position, and an oil pressure is fed to the oil chamber of a first clutch. Meanwhile, during 4-3 power-OFF down shift, a first accumulator oil pressure exerted on a control port 338 of a 4-3 control valve 330 is relatively low since a throttle opening is a low value equivalent to an idle opening, and the spool valve 332 is situated in a rising position. A speed at which an oil pressure is fed to a clutch oil chamber through oil passages 324 and 329 is increased, and a first clutch is rapidly engaged with transmission torque capacity. This constitution enables rapid production of a speed change reduced in a speed change shock and an engine brake effect.

Abstract: PROBLEM TO BE SOLVED: To dispense with memory access, such as a line buffer and to reduce a circuit scale by arranging plural color filters to output an image signal and generating a luminance signal only with the horizontal interpolation of a color information signal, including the largest amount of luminance information from among plural color information signals included in the image signal. SOLUTION: An image signal 2 consists of R, G, B signals and is successively outputted from an image-pickup device 1, in accordance with the arrangement of a color filter of a primary color system. For instance, the image signals 2 are outputted from the image-pickup device 1 in the order of RGRG, etc. on the odd numbered horizontal line and in the order of BGBG, etc. on the even numbered horizontal line. The image signal 2 is divided into a G signal and the other color signals, and the G signal is outputted from a luminance signal generation circuit 3 as a luminance signal 4 as it is. R and B signals newly generate a luminance signal 4, by means of interpolation calculation of the G signal adjoining these color signals and output the signal from the luminance signal generation circuit 3.

IPC: G06K9/00
Filed: 1990-08-31
Abstract: PURPOSE:To realize the improvement of recognition speed and the simplification of the character recognizing device by preparing plural rectangular-shaped processing sections in the vertical direction, simultaneously extracting a ruled line area and a character area against the respective above-mentioned processing sections, and expressing the recognized character and the ruled line as a character code. CONSTITUTION:A rectangular form means 102 prepares plural rectangular-shaped processing sections in the vertical direction against a recognition object image 101. An area detection means 103 detects a ruled line area or the upper and lower end of the character area, and detects the area by one line. Next, a horizontal ruled line detection means 104 decides whether the above-mentioned one line area is the horizontal ruled line or a character string. A vertical ruled line detection means 105 detects the existence of the vertical ruled line. A character recognition means 106 recognizes the character string of the area by one line decided as the character string in the horizontal ruled line detection means 104. Thus, a coding means 107 converts each character into a character code, and converts the vertical and horizontal ruled lines into a ruled line code to be outputted.
