Title: Gain controlled frequency converter circuit
Inventor: ITO TAKUMI
IPC: H03D7/14
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a frequency converter circuit capable of gain controlling by changing the base bias potential of a transistor and controlling the output gain of intermediate frequency signals. SOLUTION: A gain control NPN transistor 6 is connected parallelly to LF modulation NPN transistors 5 and 7 between the collector of an RF modulation NPN transistor 13 and a power source. Also, the gain control NPN transistor 9 is connected parallelly to the LF modulation NPN transistors 8 and 10 between the collector of the RF modulation NPN transistor 14 and the power source. The base potential of the gain control NPN transistors 6 and 9 is controlled by a variable bias power source 12. In such a manner, just by adding the gain control NPN transistors 6 and 9 to a conventional frequency converter circuit and controlling the bias potential, the output gain is lowered almost to zero and this simple frequency converter circuit of an extremely large gain control range is obtained.

Title: Signal processing circuit of recording and reproducing device
Inventor: TANIGUCHI HIROSHI
IPC: H04N9/83
Filed: 1982-12-08
Abstract: PURPOSE:To improve the S/N ratio of a chroma signal by recording a side band of a modulated chroma signal nonlinearly with much emphasis at lower level at recording and reproducing the signal through a nonlinear circuit having the inverting characteristic at reproduction. CONSTITUTION:A signal inputted to an input terminal 1 is amplified at a transistor (TR)Q1 at recording and outputted to a collector 2 of the TRQ1. Since a power supply Vp of TRs Q2, Q3 is not supplied at the recording, a positive DC voltage of the collector of the TRQ1 is applied to a junction M between the emitter and collector of the TRs Q2, Q3 and the TRs Q2, Q3 are both biased reversely, then the nonlinear emphasis characteristic at the recording side is not affected. Then, a reproducing signal from a terminal 3 is inputted at the reproduction, amplified at the TRQ2 and an output is obtained at a collector 4. In this case, the base of the TRQ1 is brought into ground potential by a diode D3, and since a diode between the collector base of the TRQ1 is biased reversely, the signal is reproduced through a nonlinear circuit having the inverting characterisitc.

Title: Heat exchanger
Inventor: OKAMOTO MASAYOSHI
IPC: F28D1/03
Filed: 1984-10-12
Abstract: PURPOSE:To reduce the operating power requirement and also to obtain a high heat exchanging performance by avoiding a clogging in the heat exchanging section by making the sectional area of a heat exchanging medium passage of a heat exchanger of a 3-pass method or more increasingly larger in a stepped manner from the inlet side toward the outlet side. CONSTITUTION:The sectional passage area of a heat exchanging medium passage 3 in each tube element 1 is made increasingly larger in a stepped manner from the inlet side toward the outlet side because the number of passages 3 is increased one at a time from the second group (b) to the fourth group (d). As the sectional passage area of the thermal medium is increased in a stepped manner from the first group where the gasification ratio is low toward the second, third and fourth groups where the gasification ratio becomes increasingly higher, the increase in the flow resistance due to the increasing volume by the gasification can be avoided. Therefore, there will be no clogging in the heat exchanging section, and the compressor that supplies the heat exchanging medium to the condenser under pressure need not bear a high load. So, its power requirement becomes small, a dry-out phenomenon is prevented, and a high heat exchanging performance is obtained.

Abstract: PURPOSE:To prevent a work from deforming and to take a product out easily by providing a driving means for moving a pawl for clamping the outer circumferential surface of the work forward and a returning means for returning the pawl. CONSTITUTION:The work 30 is fitted in the outer circumference of a cylindrical member 27 and through the rotation of a cam ring 47, a surface pawl 45 moves forth by being pressed by a tapered cam surface; and then a groove pawl 44 moves forth by being pressed by the cam surface, and thus the pawls 44 and 45 press both a fork groove 42 and a large-diameter surface 43 securely. Lastly, a press shaft 58 is energized downward through the lowering of a shaft ram 59 to lower a work retainer 60. Further, the lowering of a slide shaft 36 allows a punch 32 to move forth horizontally, thereby impressing the work 30 by an impression work part 33. After then, the ram 59 is elevated to lift the work retainer 60, and pressure is applied to a hydraulic pressure chamber 40 to elevate a piston 41, moving each punch 32 back. Further, the cam ring 47 is rotated to return the pawls 44 and 45 to their original positions and the work 30 after being worked is released.

IPC: C23C2/24
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of a hot-dip coating metal when a steel strip is hot-dip coated by perpendicularly passing the steel strip upward in a hot dip-coating bath. SOLUTION: A steel strip carrying-in part 9 having an opened lower end is disposed at a lower part of the hot dip-coating bath 4 and a pair of moving magnetic field generating coils 11, 11 are disposed to face each other at an outside of the steel strip carrying-in part 9.

Title: Electron beam length-measuring method
Inventor: NORIOKA SETSUO
IPC: G01B15/00
Filed: 1990-08-14
Abstract: PURPOSE:To enhance length-measuring efficiency by displaying respective pairs of longitudinal and transverse cursors for setting the measuring widths of first and second parts whose lengths are to be measured by superposing them on the image of a sample, so that two kinds of regions on the sample can be simultaneously set. CONSTITUTION:Image data read-out regions for measuring the lengths of widths of both a longitudinally extending pattern part P1 and a transversely extending pattern part P2 are set, and on the basis of the signals from a cursor signal generating circuit 11, a computer 13 reads out image data from a memory 31. And, from the image data in the region surrounded by cursors C1, C2, R1, and R2 on a sample image, the computer 13 obtains the length of the width of P1 extending in the longitudinal direction, and in the same way, in the region surrounded by cursors C3, C4, R3, and R4, it obtains the length of the width of P2 extending in the transverse direction. Thus, since two regions can be confirmed by one picture-image, such a miss that the cursors are set in a place out of the patterns can be eliminated, and operability and length-measuring efficiency can be enhanced.
