Title: Peaking circuit
Inventor: INAGAKI YOSHIO
IPC: H03G5/02
Filed: 1990-01-23
Abstract: PURPOSE:To prevent an influence of floating capacitance and floating inductance even at the time of peaking in a high frequency by providing a broad band amplifier IC or the like with a second semiconductor element, which has one end connected to a first semiconductor element or a capacitor and to which the forward bias is supplied, and a current source which is so connected that the forward bias current is supplied to the second semiconductor element. CONSTITUTION:The circuit constant of a resistor R3 or the like is so selected that the value of a dynamic resistor R of a diode D2 is much smaller than the value of the resultant impedance of the resistor R3 and a transistor TR Q2 viewed from the collector side, thereby practically adjusting the extent of peaking by the value of the dynamic resistor R3. Consequently, an inductance LB3 and a capacitor CB3 are merely added as current sources to a variable resistor 7 which adjusts a bias current ID though the inductor LB3 and the capacitor CB3 related to a bonding wire and a bonding pad, which are used to connect the variable resistor 7 to the outside of the IC, are generated, and the peaking characteristic of the circuit is not affected, and peaking is easily applied in a high frequency range.

IPC: H01J29/50
Filed: 1987-01-26
Abstract: PURPOSE:To restrict fluidization of an extra thick part in a direction in which a dent is generated and hence to improve precision for recessed part shaping by forming a groove part at least on a side of vertical deflection corresponding to a periphery of the recessed part and locking this groove part to form said recessed part.

Thus, when the annular groove part 24 is formed in advance and this groove part 24 is locked to perform a coining process for the recessed part 22, fluidization of an extra thick part in a direction in which a dent is generated can be remarkably restricted upon the formation of the recessed part, and the fluidization of the extra thick part can be centralized in a direction in which the diameter of the lower hole is reduced. Hence, losses can be prevented from being generated and the recessed part can be formed with uniform and high precision for its shaping.

Title: Feeding method of welding wire
Inventor: ANCHI AKIHIKO
IPC: B23K9/12
Filed: 1979-02-09
Abstract: PURPOSE: To realize stable, long distance feeding of wire, free from buckling, in spite of unfavorable conditions in the midway, by setting the interval between adjoining wire feed devices between wire let-off part and welding torch and the interval between the same devices and welding torch in the foremost position, in the specified linear distance.  
     CONSTITUTION: When a wire 2 makes loops 6, 6' between feed devices A, B provided between a wire reel 3 and a welding torch 5, the frictional resistance against the conduit inner wall increases, so that the feed resistance Fm also increases. When this value and end load Fo are plotted by varying the number of turns of the loop, the relation becomes as shown. The feed resistance capable of feeding stably without  buckling is Fm=10kg, and the end load capable of maintaining stable arc is Fo=0.5W1kg. Hence, the curve passing through the point of intersection Z, i.e., the number of turns 2.5 has the maximum overall length of 2.5m, seeing one turn is 1 meter. When the distance L 2  is less than 1m, since the weight of device B is transmitted to the torch, then let L 2 =1W2.5m. On the other hand, when distance L 1  or L 1 ' is 8m, the number of turns is 8, and suppose the output of device A is 10kg, and Fm<10kg, maintaining Fo>0, thus permitting feeding, so that let L 1  or L 1 ' <8m.

Filed: 1983-02-01
Abstract: PURPOSE:To attain to enhance the measuring reliability of a dew point, by detecting the difference between resonance frequencies of a hermetically sealed crystal vibrator and a crystal vibrator exposed to gas to be detected. CONSTITUTION:When a power source is closed, the difference between resonance frequencies of crystal vibrators Q1, Q2 is set in a setting circuit ST1 as an initial value which is, in turn, compared with the output frequency of a mixer M in a comparison circuit CM1 and, when both values are same, output is generated from a drive circuit DR and a heater cooler A is operated as a cooler. Because the vibrator Q2 is exposed, dew is formed on the surface thereof at a dew point and the mass thereof is increased while the resonance frequency thereof is lowered as shown by the drawing. On the other hand, because the vibrator Q1 is hermetically sealed, there is no dew formation and, therefore, the difference between the resonance frequencies of both vibrators becomes large and, when the difference reaches a predetermined values DELTAf more, cooling is stopped while the oscillation frequency of the vibrator Q1 is taken in an operation circuit CU to be converted to a dew point. At the same time, the output of a temp. detecting circuit TM is taken in the circuit CU to measure atmosphere temp. while the absolute humidity and relative humidity are calculated from the dew point and the atmospheric temp. to be displayed by a display apparatus DS.
