Title: Stabilized power supply circuit
Inventor: SHIRAI KOJI
IPC: H02H3/24
Filed: 1993-10-06
Abstract: PURPOSE:To prevent conditions such as the destruction of any element and the emitting smoke or burning of a substrate by cutting off output and maintaining this output cut-off state with a flip-flop circuit when an output terminal is short-circuited. CONSTITUTION:When a Vo is turned to be in the short-circuited state after a Vin is turned on and initial reset is applied, the potential of the Vo is turned to a GNDV level and a potential at the potential dividing point of R41 and R42 is also turned to be at the GND level. Therefore, a constant current I21 flows through an emitter/base D21 of a transistor Tr 21 and transistors Tr 21 and Tr 22 are turned on. Thus, the S terminal of a flip-flop circuit 3 is made LOW, a transistor Tr 31 is turned on, the collector potential of a transistor Tr 32 is made HIGH, and the flip-flop circuit 3 is set. Accordingly, a transistor Tr 1 is turned on, a base current I60 of a transistor Tr 43 is pulled out, and the output is cut off. Even when the short-circuited state of the Vo is canceled, the flip-flop circuit 3 keeps the set state.

Filed: 1994-10-17
Abstract: PURPOSE: To reduce thermal resistance at the time of flip-chip connection. CONSTITUTION: A semiconductor element 11 is bonded through solder bumps 13 with a circuit board 15. An insulating film, i.e., an oxide film 14, is formed around the bump 13 at the time of bonding the semiconductor element to the circuit board or thereafter. The periphery of the solder bump 13 is filled with a low melting point metal 17 for lowering the thermal resistance and the heat dissipation performance is enhanced between the semiconductor element 11 and the circuit board 15. Since the gap between the semiconductor element 11 and the circuit board 15 is filled compactly with a material having high thermal conductivity, thermal resistance is reduced.

Abstract: PROBLEM TO BE SOLVED: To determine a state of a sample flow, properly correct measured data and improve reliability of data, by counting a total count of particles passing in a measurement time, and calculating an estimated count of particles subjected to image-processing. SOLUTION: A laser light flux 14 from a laser 15 is reflected at reflecting mirrors 18, 19 and projected onto a sample flow 110 in a flow cell 100. When a light detection circuit 22 detects particles, a driving circuit 1a makes a flash lamp 1 emit light, a TV camera 8 picks up a still image of the particles, and a particle detection-processing part 40 carries out image-processing to all particles in the image. At this time, a count of all particles passing in a measurement time is counted, and an estimated count of particles subjected to the image-processing is calculated from the count of all passing particles. The estimated count of image particles is multiplied by a preliminarily obtained particle image effective coefficient, thereby calculating a count of effective image particles.  Only the effective image particles of the count from a larger size among sample particle images are determined as a measurement particle image.

Abstract: PURPOSE:To easily discriminate a live line from a dead line through a cover, by a method wherein a liquid crystal element is operated by the voltage difference between AC voltages induced in respective current collection plates when AC voltage is applied to a plurality of cores of an insulated wire. CONSTITUTION:A current collection plate 3 and a current collection plate 4 are different in a geometrical relative position with respect to three core wires 1a, 1b, 1c. Now, when symmetric three-phase voltages are applied to the core wires 1a, 1b, 1c, voltages different in a phase are induced in the current collection plates 3, 4. By operating a liquid crystal display element 5 by applying both voltages to said display element 5, it can be displayed that a three-phase insulated wire 10 is in a charge state. The difference voltage appearing between the current collection plates 3, 4 is different by the relative positional relation between the current collection plates 3, 4 and the core wires 1a, 1b, 1c. When the mount positions of the current collection plates 3, 4 are successively rotated by 360 deg. around the core wires symmetrically arranged of the three-phase insulated wire 10, since the max. value appears at every 60 deg., the areas of the current collection plates 3, 4 are selected so that the min. value of said difference voltage becomes sufficiently larger than the min. operation voltage of the liquid crystal display element 5.

Abstract: PURPOSE: To form a homogeneous amorphous metallic thin film without constraint of a starting material by partially immersing a rotating roll in a bath of a molten material, sticking the picked up material to a supporting body that is in close contact with the rotating roll and thereby transferring the material. CONSTITUTION: An endless band 10 is moved around an upper and lower rotating rolls 11, 12 in a vertical loop. A roll 20 that rotates in close contact with the band 10 is supported by a holding equipment 8, raised/lowered, and partially immersed in a heating bath 5 of a molten metal or alloy. The band 10, when passing between the rolls 12, 20, has the adherence of the molten material picked up by the roll 20 and thus transfers the material. Since the band 10 is cooled when passing around the upper roll 11, the molten material in transit is rapidly solidified to form an amorphous metallic thin film. This metallic film is taken out with the help of a drawing equipment 32 provided closely to the band 10.
