Title: Address conversion buffer device
Inventor: MIZUKAMI KENGO
IPC: G06F12/10
Filed: 1991-08-21
Abstract: PURPOSE:To decrease the capacity of a hardware without decreasing the number of words registered on an address conversion buffer. CONSTITUTION:The address conversion buffer is bisected into an outline buffer 4 and a detail buffer 6. The former registers the pair of a virtual space indentifier 16 and a segment number 17, and the latter registers the pair of a page number 19 and a read address 20 at the head of that page. Since a pair in the outline buffer 4 is made respectively correspondent to the plural pairs in the detail buffer 6, the capacity of the hardware for registering the virtual space identifier 16 and the segment number 17 can be reduced in the case of registering the converted pairs of differing the page numbers although having the same virtual space identifier 16 and segment number 17. Thus, since much more converted pairs rather than the conventional number can be registered when the capacity of the hardware is the same, the hit ration of address conversion is increased.

Title: Water quality measuring method
Inventor: WATANABE SHOJI
IPC: G01N21/33
Filed: 1992-09-02
Abstract: PURPOSE:To stably perform measurement for a long period of time with high accuracy without having a contaminant sticking to a detection part by arranging a light irradiation means and a light detection means facing each other on the way of the flow down of a flowing water film so as to hold the surface of the flowing water film between both means. CONSTITUTION:The tray 31 of a water film forming tank 3 having a square structure is inclined as a whole and water to be inspected overflows from one side 31' of the tray 31. The distribution plate 32 laterally arranged to a part of the tray 31 prevents the fluctuation of the surface of the water due to the flow of the water to be inspected falling from a distribution tank 2 to stabilize the surface of the water of an overflow part. Further, the width of an overflowing water stream is ensured by the guide plates 33 provided to both ends of the overflow part to stabilize the thickness of the water stream. The flowing water film 4 formed by the tank 3 falls under gravity and the intensity of transmitted light is measured by the light source generating device 5 and detector 6 arranged on the way of the flowing water film 4 so as to be opposed each other on both sides of the water film 4. At this time, since a light guiding cylinder 52 and a condenser 63 are arranged so as not to come into contact with the flowing water film 4, a detection part is not contaminated and measurement stable for a long period of time can be performed.

Title: Resistor for speed controlling car air-conditioning blower
Inventor: YOSHINO MAKOTO
IPC: B60H1/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a resistor for speed controlling a car air-conditioning blower, capable of reducing draft resistance of blast air. SOLUTION: This speed controlling resistor 4 is set up so as to accord the axial direction of each winding shaft of three coiled resistant elements 8 to 10 with the blast direction (draft direction) of blast air flowing in an air- conditioning case. Therefore, even if the winding number of a coil is increased, draft resistance will not be augmented at all. Furthermore, since the coiled resistant elements 9 and 10 are set up in series, this draft resistance is reducible to half or so, as compared with the case of apposing them in parallel.

IPC: B23Q1/62
Filed: 1984-11-09
Abstract: PURPOSE:To make a positional error due to yawing compensable with a simple structure, by detecting a yawing variable, while calculating the positional error in the direction of X-Y axes due to yawing. CONSTITUTION:Each zero point of two scales 6X-1 and 6X-2 of a base plate is set down to a zero position, and a span between both scales is set to Lx. If an A point is positioned to a desired position (i), a pointer 10X-1 indicates i+nX while a pointer 10X-2 indicates i-mX due to yawing, respectively on these scales 6X-1 and 6X-2 in consequence. A tilt angle due to yawing at this time is set down to alpha, and a slip DELTAX out of the desired position (i) of the A point is expressed with an equation of DELTAX=lsinalpha from a distance l out of a center line of the A point, while the tilt angle alpha is found out of an equation of alpha= sin<-1>[(nX+mX)/Lx]. Therefore, it is calculable with DELTA=l.(nX+mX)/Lx. Here, if a bed plate 1 is moved as far as -DELTAX, the A point can be positioned to the desired position (i) as in one-dot chain line.
