Title: Material for joining heat exchanger parts made of aluminum and joining method using the material
Inventor: YANAGAWA YUTAKA
IPC: B23K1/00
Filed: 1992-09-07
Abstract: PURPOSE:To join aluminum materials at a lower temp. and to reduce costs by specifying the compsn. of the material for joining heat exchanger parts made of aluminum. CONSTITUTION:The material for joining the heat exchanger parts made of the aluminum is constituted by incorporating 0.1 to 1.5wt.% Mg, 1.5 to 10wt.% Sn and 0.005 to 7wt.% Al therein, incorporating one or two kinds of O to 5wt.% Cu and 0 to 0.5wt.% Ti therein and constituting the balance of Zn and inevitable impurities. As a result, the joining temp. in a brazing stage of the heat exchangers is lowered and the formation of the thinner parts is possible. Particularly the Zn-base alloy which is the material for joining is electrochemically baser than tubes and has a sacrificial effect on the tube material, and therefore the long term reliability against the pitting of the tube material is assured.

IPC: H05K3/34
Filed: 1994-10-28
Abstract: PURPOSE: To provide a printed wiring board having little danger of getting hurt of a solder resist film and a conductor pattern at the time of mounting electronic parts or the like. CONSTITUTION: A protective mark 7c is printed by silk screen printing on the surface of a solder resist film 6 covering the extended parts 3a, 3b of an extended pattern 3 near the peripheral part of an insulated substrate 2 so as to be along the peripheral part.

Abstract: PURPOSE:To attain the automatic production of a discriminating dictionary to save its man-hours, time and cost by applying size distortion processing and rotary distortion processing to the component segments of a basic pattern to give the distortion to these segments in the revolving direction. CONSTITUTION:An operator supplies a basic pattern on the screen of a graphic display 6 by indicating the end point of the pattern with a cursor or a light pen. Then the operator designates the maximum and minimum magnification ratios MA and MIN and the rotary distortion angle N through a keyboard. A pattern production part 5 receives the basic pattern, the magnification ratios and the distortion angle to store them in a memory and also sets the magnification ratio of the size distortion. In a rotary distortion processing mode, the rotary distortion is applied to each quadrant with the center of a given defined as an original point and according to a designated rotary angle. Thus a rotary distortion pattern is produced. While a shift distortion pattern of each size distortion pattern is produced by the shift distortion, i.e., a kind of rotary processes.

Title: Power-up pulse generating circuit
Inventor: ANDORIYUU EMU RABU
IPC: H03K17/22
Filed: 1990-10-02
Abstract: PURPOSE: To improve the reliability of circuit operation by providing the power-up pulse generation circuit with a source-drain path connected between a power supply and an internal node, a trigger field effect element connected to reference potential, a capacitor, and a detecting field effect element. CONSTITUTION: At the time of power up, a capacitor 14b boosts the voltage of an output terminal OUT together with 1st power supply voltage. On the other hand, a capacitor 13 holds the voltage of an internal node N at a 2nd power supply voltage value Vss and increases a power up signal. When a 1st power supply voltage Vdd reaches one P channel voltage Vt (threshold voltage), a selective P type load transistor(TR) 14a is turned to on. When N channel voltage Vt is lower or the same than/as the P channel voltage Vt , an N type output detecting TR 16 is started to be switched to an on-state. Thereby the voltage of the output terminal OUT is turned to a low level, and the voltage Vdd reaches a normal level necessary for exciting all other circuits.

IPC: G01N30/74
Filed: 1993-10-22
Abstract: PURPOSE: To enhance the sensitivity and S/N of a detecting system by directing exposure light passing through the incident bending part of a capillary detector cell, so that the light goes along the central axis of a center leg part. CONSTITUTION: A capillary 43 inserted in a center hole in a disc 45 is bent by heat and formed into a Z-capillary (Z-cell) 54 having a center leg part between an incident bending part 42 and an exit bending part 46. In order to determine the direction, diameter, and parallelism of an incident beam of exposure light, the point of incidence of the beam on the bending part 42, and the position of a detector relative to an output beam, the insert 413 of a capillary lens holder (imaging system) 40 is inserted into a hole 412 in a jig 48 to position the bending part 42 inside the incident beam and to accurately align a spherical lens 41 with the bending part 42.  The beam of exposure light incident from the bending part 42 is transmitted through the center leg part and goes to the detector through a hole in a jig 417, and since the beam passes through an inspecting solution in the center leg part that is slightly longer than the bore of the capillary, sensitivity and S/N are enhanced.

Title: Adapter device for camera
Inventor: NISHIMURA AKIMASA
IPC: H04N5/225
Filed: 1990-10-02
Abstract: PURPOSE:To make a camera small-sized and light-weight and to prevent a video floppy from being taken out during interval photographing by disabling an open/close cover to open with a tripod adapter fixed to the camera. CONSTITUTION:An adapter 1 is so constituted that a disk drive open/close cover 14 is covered with the adopter 1 at the time of setting it to a camera body 4. When the tripod adapter 1 is attached, the disk drive open/close cover 14 of the camera is covered. Thus, firm and large-sized attaching screws 13 are not required for the camera main body 4, and the camera is miniaturized. Since the disk drive open/close cover 14 cannot be opened by attachment of the tripod adapter 1, the damage of the tripod adapter 1 due to the operation force for replacement of a video floppy 16 is avoided, and the video floppy 16 is prevented from being taken out by carelessness especially during long-time interval photographing.

Abstract: PROBLEM TO BE SOLVED: To calculate saddle type aspherical components from interference measuring data with high accuracy by fitting the error component of a test surface by using the functions shown in specific formulae and making the magnitude and rotating direction of the error component calculable. SOLUTION: The transformation formula of an X-Y coordinate system into an x-y coordinate system by an angle of rotation of θ/2 is related to X=xcos(θ/2)+ysin(θ/2) (formula I) and Y=-xsin(θ/2)+ycos(θ/2) (formula II). Formula III, f[a,θ]≡-a (x**2-y**2)cosθ+(2xy)sinθ} which is obtained when formulae I and II are substituted into a (X**2-Y**2) becomes the generalized formula of saddle type aspherical components. The data [i,j] are interference measuring data and represent the erroneous abberation amount at an address i,j. When the interference measuring data are optimumly fitted by using the formula III, the magnitude (a) and rotating direction θ of the erroneous aberration amount can be calculated by the method of least squares. This is such a relation that gives the magnitude (a) and rotating direction θ which make SUM=-Σi, j data[i,j]-f[a,Ω]**2 (formula IV) the minimum.
