Title: Roberval balance
Inventor: KAWAHARA NORIO
IPC: G01G21/24
Filed: 1983-02-28
Abstract: PURPOSE:To form a highly sensitive, durable roberval balance having a thin plate thickness, by providing supporting points, to which a force is applied in the direction toward a fixing part when a load is applied on a receiving pan, at points, which are deviated to the fixed point from the movable ends of links; and providing the supporting points of the fixed part for the links at the positions, which are deviated to the movable side from the fixing ends of the links. CONSTITUTION:When a load W is applied on a receiving pan 1, an arm 22 is subjected to bending moment M in the clockwise direction. The upper end of a movable post 21 receives an inward force F1. The lower end thereof receives an outward force F2. Therefore, elastic supporting points 13 and 14 on the movable side receive only a tensile force. Parallel links 4 and 5 also receive only the tensile force. Therefore, elastic supporting points 11 and 12 on the fixed side receive only the tensile force. When the load is applied to the receiving pan in a deviated manner, the magnitude of the bending moment is changed. Since the arm 22 is protruded by the length of radius of the pan, the direction of the arm is not changed. Therefore, only tensile stress is yielded at four elastic supporting points and the parallel links 4 and 5, and compression stress is not yielded. Therefore, the thin elastic supporting points having small spring constants can be used, and sensitivity can be increased without decreasing load resistance.

Title: Switching power supply and drive control circuit of its main switching element
Inventor: SATO HIDEKI
IPC: H02M3/28
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To reduce the power loss in a main switching power supply by shortening the turn-off time, without making the drive control circuit of a main switching element complicated. SOLUTION: Between a main control circuit 4 and a main switching element 2, a differential circuit is composed of a limiting resistor 6, a capacitor 7, a bias resistor 8, a parasitic capacity 9 of the main switching element. The constants of the limiting resistor 6, the capacitor 7, and the bias resistor 8 for constituting the differential circuit are set, so that the voltage of a gate terminal 2a is set to the threshold of the main switching element 2 or more when an 'on' signal is sent, and the voltage is set to 0 V or less when an 'off' signal is sent, thus applying reverse bias to the gate terminal 2a when the off signal is sent.  By applying the reverse bias, charge being charged to the parasitic capacity 9 of the main switching element 2 is rapidly discharged, and the main switching element 2 is turned off, thus drastically reducing the turn-off time of the main switching element 2.

Abstract: PURPOSE:To lighten the burden for constituting a device, by utilizing a scan-in circuit existing in an LSI, and an external input terminal for said circuit, executing freezing control of an external output terminal of the LSI, and reducing the number of external wires and the quantity of hardware. CONSTITUTION:A scan-in circuit 20 is utilized for not only scan-in of a latch 19 but also freezing control of an external output terminal 15. Therefore, a control input 16 of each output freezing circuit 13 is connected to the scan-in circuit 20 by a common line 16', and to the common line 16', a scan address being intrinsic in an LSI, which does not correspond to any latch 19 is assigned.

Title: Chip-mark detector for hybrid exposure
Inventor: ASARI TOSHIHIRO
IPC: G03F7/20
Filed: 1987-02-17
Abstract: PURPOSE:To compute the position of the center of gravity accurately even for a ring mark, by counting the number of spots on a mark scanned by a beam, analyzing the shape of the mark and obtaining the position of the center of the gravity of a mask pattern. CONSTITUTION:When a sample is scanned with an electron beam, a composition judging unit 26 receives a signal from the surface of a material and outputs H for metal and L for a silicon wafer. A mark-shape analyzing unit 27 memorizes the position signals of (x) and (y) coordinates of the electron beams only when the H signal is received and counts the number-signals of the beam spot at that time. An operating unit 28 receives the coordinates of the beam spot and the number of the spots at that time from the mark-shape analyzing unit 27 and performs operation. Since the positioning can be accurately performed even for a ring mark, the pattern is not deviated in exposure.

IPC: B21D51/16
Filed: 1995-01-30
Abstract: PURPOSE: To install a branching tube without interfering a flow of fluid by pulling out a steel ball to outside of a mold from a through-hole, warping a part of the metallic tube in the periphery of the hole with the steel ball arranging the shape of the warping port of metallic tube as the mold, and forming a collar around the hole.

A pull 5 of a pulling device above the form is engaged with a catch 21 and pulled upward. As a result, the steel ball 2 is raised, pushing up the periphery of the hole 1 of the tube A, pressing it tightly against the through-hole 41 of the form 4. The steel ball 2 is further raised and pulled out above the form 4. After that, a transporting tool 3 and the form 4 are removed, so that the tube A with the collar is obtained. The collar 6 thus formed is used for installing a branching tube. When a branching tube is connected with the collar 6 inserted in it, the tip end of the branching tube is prevented from projecting inside the metallic tube A, making a flow of fluid smooth without a narrowed part.
