Title: Method and apparatus for alignment of mask and work
Inventor: GOTO MANABU
IPC: G03F9/00
Filed: 1994-10-06
Abstract: PURPOSE: To align a mask with a work with a high precision by an aligner which uses a light having a wavelength different from the wavelength of an exposure light for alignment by a method wherein the magnification at the time of the exposure light application agrees with the magnification at the time of the non-exposure light application. CONSTITUTION: A distance between a mask M and a projection lens 3 and a distance between the projection lens 3 and a work are adjusted while the change of the focal distance of the projection lens 3 following a wavelength and the movement of a main surface are taken into account and the light path length of an optical system is so adjusted as to make the magnification at the time of non-exposure light application equal to the magnification at the time of exposure light application. Then the non-exposure light is applied to the mask M and a work drive stage 5 or a mask drive stage 2 is moved so as to have the alignment mark of the work agree with the alignment mark of the mask.  Instead of adjusting the distance between the mask M and the projection lens 3 and the distance between the projection lens 3 and the work, the light path length may be adjusted by inserting an optical member such as a parallel flat plate.

SOLUTION: This Zn-Mg series plated steel sheet has Zn-Mg series plating layers with a two layer structure in which a Zn-Mg layer contg. <=0.5% Mg and a Zn-Mg layer contg. 2 to 18% Mg are successively formed on the surface of a base steel respectively as a primary layer and a secondary layer or with a three layer structure in which <=0.5% Mg as a primary layer, 2 to 6% Mg as a secondary layer and a Zn-Mg layer contg. 9 to 18% Mg as a third layer are successively formed on the surface of a base steel. In the case a Zn-Fe alloy layer or a Zn-Fe-Mg alloy layer having <=0.5μm thickness is formed on the boundary between the base steel and the primary layer, the plating layer excellent in adhesion can be obtd. By subjecting it to contacting treatment in an Ni ion-contg. zinc phosphate treating soln. after vapor deposition plating, blackening treated coating film can be formed on the surface of the plating layer. Since it has self-restoring operation, even if there are flaws, the black surface excellent in designing properties can be maintained over a long period.

The sludge is then scraped by this scraper 7 and is ejected to the ensuing treating stage. The large foreign matter 5 cannot enter the respective annular valley parts of the respective rolls 1, 2. The foreign matter 5 pushes the other roll 2 toward the roll 1 in the specified position and moves the other roll in a distant direction, thereby parting the gap between the rolls 1 and 2. This foreign matter is recovered into a recovering box through a conveyor 6 for carrying out.

Title: Recorder and read method for the recorder
Inventor: KANEKO KIYOSHI
IPC: H04N1/04
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a recorder that prevents waste of power and a read method for the recorder. SOLUTION: When a time count section 33 counts that a signal ϕTR 40 is not received within a prescribed time based on the signal ϕTR 40 that is used without fail when a scanner unit is in operation, the section 33 provides an output of an oscillation stop signal to close a switch 32 to stop the oscillation. When the section 33 counts the input of the signal ϕTR 40 within a prescribed time, the signal ϕTR 40 is used for an oscillation start signal, the section 33 opens the switch 32 to start the oscillation as an oscillation control method. Thus, when the scanner unit 51 is in a standby state, an oscillation control section 31 stops tentatively the oscillation of an oscillation amplifier 30 to prevent waste of the power of the entire scanner unit 51.

Title: Simple splicing method for multimode optical fiber
Inventor: ONODERA TSUTOMU
IPC: G02B6/24
Filed: 1985-10-30
Abstract: PURPOSE:To eliminate the need for the control of the interval between end faces for fusion-splicing, to simplify the splicing work and to obtain a small loss by extending a practical extent of press-in of optical fibers. CONSTITUTION:A practical extent of press-in l=L-d is extended to 30-180mum to omit the control of an interval (d) between end faces. If the interval between end faces is 40-160mum, optical fibers are spliced with <=0.01dB loss independently of the interval between end faces. consequently, + or -60mum deviation is allowed if the interval (d) between end faces is set to 100mum. That is, the variance is held down within + or -60mum when optical fibers 14 will be so cut that a length (x) is 140mum. Thus, the end part of a coating part 12 is brought into contact with a stopper 22 only to eliminate the need for the control of the interval (d).

Filed: 1991-09-24
Abstract: PURPOSE:To conduct complementary control operations of two switching transistors at the same timing by providing a voltage comparator for comparing outputs of first and second output detectors with a reference voltage to control to switch the primary side of a power transformer. CONSTITUTION:When a control transistor 55 is turned OFF by a control signal supplied to a terminal 56 of a power source, a predetermined divided voltage is supplied to turn ON a transistor 53, and a transistor 28 is turned ON to turn ON a power source switch.

Title: Component chuck device
Inventor: SHIRAISHI TOSHIRO
IPC: B25J15/08
Filed: 1987-09-30
Abstract: PURPOSE:To hold a plurality of parts having different dimensions in height and insert them in the prescribed places with one kind of a chuck body, by causing a plurality of presser pins of the parts to locate at positions of members for holding parts which have different distances from the point of each member and allowing the presser pins to be movably mounted so that they may perform rising and setting actions from/to the holding face of the claw member and always energizing the presser pins to protrude from the holding face of the foregoing claw member. CONSTITUTION:A chuck body is moved on a circuit substrate 32 and permits a claw member 17 to move in the direction of the arrow A to insert two pieces of lead wires 31 into through holes. After a lower part 30a of an electronic component 30 abuts on the circuit substrate 32, the claw member 17 moves further a prescribed distance in the direction of the arrow A. In such a case, the claw member 17 lowers as the holding face 19 of the claw member slides between its face 19 and the side parts of the electronic component 30 and since the holding member 21 compresses a spring 22, the presser pins 24 of the component are kept in a state that the pins 24 abut on an upper part 30b of the electronic component 30. Thus, this device allows clinch claws 34 to come closely into contact each other to bend up the lead wires 31 and then, the electronic component 30 are fixed tentatively to the circuit substrate 32.

Title: Individual certifying device
Inventor: NAKAI TOSHIO
IPC: G06K17/00
Filed: 1987-09-30
Abstract: PURPOSE:To increase certification accuracy by overlapping the characteristics of the face picture of a person to be certified recorded previously on a screen, which the person to be certified can see, and the face picture of the person to be certified, which is image picked-up on a real time basis, at the same size, and simultaneously projecting them. CONSTITUTION:While seeing the face picture, which is image picked-up on a real time basis, a person to be certified 1 vertically or horizontally moves his face, or changes his angle in respect to a camera so that is may correspond to the characteristics of the face, which is projected on a screen 2 and has been recorded beforehand. Consequently, the photographing angle of the face picture of the person to be certified inputted at the time of certification corresponds to that of the face picture used for the extraction of the face picture data for collating, and vertical and horizontal dislocation is eliminated. Thus, a huge device for a pattern matching for the offset of the dislocation can be eliminated, a means to decide consistence/inconsistence can be easily constituted, in addition, the mixture of an error at the time of the pattern matching of the offset is eliminated, and the certifying accuracy can be increased.
