Title: Heat exchanging type fan
Inventor: YARI KENTAROU
IPC: F28F5/00
Filed: 1984-02-14
Abstract: PURPOSE:To reduce friction between a seal member and a partitioning plate by a method wherein the section of the seal member is made into V-shape and the length of one side of the V-shape at high-temperature side is made longer than the other side of the V-shape at low-temperature side. CONSTITUTION:The ring-shaped seal member 13, having V-shape and one side of the V-shape at the high-temperature side is longer than the other side of the V- shape at the low-temperature side, is attached to an outer peripheral plate 12. The radial length of the V-shape seal member 13 at the side of high-temperature circulating airflow 24 is made shorter than the same at the side of low-temperature cooling airflow 25. According to this method, the deformation of a blade in low temperature direction due to a temperature difference is corrected by the increase of centrifugal force at the low temperature side and necessary rotating number may be secured without increasing the frictional force of rotation between the seal member and the partitioning plate while the heat exchanging efficiency as well as the durability of the seal member may be improved.

Title: Method for checking seal on semiconductor element
Inventor: HONMA YASUAKI
IPC: H01L21/66
Filed: 1989-02-03
Abstract: PURPOSE:To make it possible to judge the presence or absence of a stable seal by arranging a semiconductor element to be checked between two facing electrodes, and measuring electrostatic capacitance between the two electrodes. CONSTITUTION:In laser sealing, a part of the surface of a semiconductor element 3 is removed by laser light, and the dent of a laser sealed part is formed. Thus, the volume of the element 3 is changed. The change in volume appears as the change in electrostatic capacitance. A sucking hole 6 is provided at the center of a metallic sucking arm 5. The arm 5 serves the role of another electrode which forms a pair together with an electrode 1. At first, the element 3 is sucked with the arm 5 and moved to the position of the electrode 1. The arm 5 is lowered, and the element 3 is pushed to the electrode 1. Under this state, the electrostatic capacitance between the electrode 1 and the arm 5 is measured. When the measured value is higher than a specified value, no sealing is judged.

While those chroma signals converted to the low band are also turned into the original chroma signals. These chroma and video signals are supplied to a mixing circuit 1f and turned into the normal composite signals. In the reproduction mode of the deck 1, a reproduction command is supplied to a reproduction detector (i) from a system controller 1h. Then the output of the detector (i) is supplied to an output switch (k), and the output signals of the circuit 1f of the deck 1 are supplied to an RF converter (l) and a buffer (m) and delivered outside as the RF-out and line-out signals respectively.

Title: Analog-digital converter
Inventor: OGAWA SEIJI
IPC: H03M1/50
Filed: 1983-02-18
Abstract: PURPOSE:To obtain a wide operating range with prescribed accuracy by inputting an output of an integration device to a comparator, holding it after charge/ discharge of a capacitor of the integration device is repeated for a prescribed time by a flip-flop and AD-converting the output voltage of the integration device. CONSTITUTION:The integration capacitor 4(C4) is discharged at first, a holding switch 2 is closed and a discharge switch 12 is opened. An input current flows, a charge is stored to the C4, a comparator 6 is operated and a flip-flop (FF)8 is set. Thus, the discharge switch 12 is operated, the C4 is discharged and when an integration device output goes to phiv, the FF8 is reset by an output of the comparator 7 and the integration is started. After this operation is repeated for a prescribed time, the hold switch 2 is opened and an output voltage of the integration device in this case is converted by an AD converter 9. Thus, since the information remains with integration, a dead time does not almost exist and the operating range is widened without being limited by a power supply voltage.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to perform a cutting action smoothly as a pretreatment when stitching a part with a large thickness such as a border. SOLUTION: This method for stitching the edge of a long article automatically is to arrange and stitch both right/left ends of toweling in its width direction while running a long article of toweling, and cut the long article at any appropriate position on both right/left ends in the width direction of the long article, if necessary, until the long article reaches its stitching position. Further, running force is supplied to the long article by a running means 9 at a position before the described cutting position, in addition to the feed of the long article at the stitching position. Besides, the running force to be supplied to the long article at the position before the described cutting position is set lower than the feed rate, at least, at the time of cutting.  Therefore, it is possible to remove the edge of the long article and stretch the running long article tightly at the stitching position and at the position before the described cutting position.

Title: Electrical signal driving circuit
Inventor: YOKOYAMA TAKEO
IPC: H03H11/02
Filed: 1987-02-06
Abstract: PURPOSE:To accelerate response speed and to reduce power consumption, by constituting an input stage to an insulating interface device with the emitter- follower of a transistor, and coupling between the emitter and the base of the transistor so as to connect the anode to the emitter and the cathode to the base, respectively. CONSTITUTION:The input stage 10 to a capacitive insulating interface device 14 consisting of an ultrasonic wave solid-state propagation medium using an ultrasonic wave is constituted of the emitterfollower of the transistor Tr1. A part between the emitter and the base of the transistor Tr1 is coupled with a diode D so as to connect the anode to the emitter and the cathode to the base, respectively. Therefore, it is possible to prevent the trailing edge part (p) of pulse response 20 from being increased even when an emitter resister R in the emitter follower of the transistor Tr1 is increased. Consequently, since it is not required to decrease the value of the emitter resistor R compulsorily, it is possible to reduce the power consumption, and to obtain fast pulse response.
