Title: Cassette ribbon detection circuit
Inventor: ISHII TETSUYA
IPC: B41J35/36
Filed: 1989-03-31
Abstract: PURPOSE:To provide the title circuit having long life and generating no erroneous operation by mounting a switch means detecting the presence/absence of the mounting of a ribbon cassette to close/open a feeder line and a photointerruptor means wherein a light emitting circuit is provided to the feeder line. CONSTITUTION:When a cassette is mounted, a switch means S is closed to supply a current to a light emitting diode D. The emitted light EL from the light emitting diode D is absorbed and scattered by the surface of a ribbon in a ribbon present state. Therefore, the base circuit of a phototransistor Q is not driven and the collector circuit of the phototransistor Q is cut off and the output OT of a CMP becomes almost 0V to output the effect that the ribbon is not finished. In a ribbon finish state, the reflected light RL from the surface of the ribbon is inputted to the base circuit of the phototransistor Q and the collector circuit of the phototransistor Q is brought to a continuity state and the output OT of the CMP shows the finish of the ribbon. When the cassette is detached, the switch means S is opened to cut off the supply of a current to the light emitting diode D and, by this mechanism, the output OT of the CMP senses the detachment of the cassette.

Title: Magnetic field generating device
Inventor: ANDO HIDEO
IPC: H04N5/84
Filed: 1987-03-31
Abstract: PURPOSE:To minimize a leakage of magnetic field at a magnetic field leading out part and improve the magnetic utilization efficiency, thereby lessening electricity consumption by forming a cross section of a magnetic flux leading out part in the form of wedge where its cross section decreases along its long axis from a combined part with a magnetic core. CONSTITUTION:When a magnetic coil 32 is energized by supplying a current to its coil 32, magnetic flux is discharged from a magnetic core part 34 toward a region where a light beam irradiation of a photoelectric-magnetic recording film 24 is practicable from a magnetic flux discharge plane 37A. Accordingly, the photoelectro-magnetic recording film 24 is exposed to magnetic flux that is perpendicular to its plane. Magnetic flux which is passing through its film 24 enters into a yoke 39 through a space and is feedback to the magnetic core part 34 which is magnetically and mechanically coupled to the yoke. Such a magnetic field generating device 30 is formed in the form fo wedge where the thickness of a magnetic flux leading out part 37 becomes thinner as its part comes near from its center part up to both pointed ends and then, its configuration assumes the form so that the whole surface area may become smaller. Thus, a leakage of magnetic field from the surface of the magnetic flux discharge part 37 is limited to a small extent and magnetic flux generated is efficiently utilized.

Title: Manufacture of material for vacuum circuit breaker electrode
Inventor: KONO TORU
IPC: C22C1/04
Filed: 1988-03-31
Abstract: PURPOSE:To intentionally deteriorate the strength of the title material and to improve the characteristics such as deposition resistance by mixing powdered Cr and powdered Cu, compacting the resulting powder mixture, and subjecting the resulting green compact to sintering and compression working under respectively specified conditions to make the sintered compact high-density. CONSTITUTION:The green compact of the mixture of powdered Cr and powdered Cu is sintered at a temp. lower than the melting point of Cu by 60-100 deg.C, and the resulting sintered material is heated to 600-1000 deg.C and subjected to compression working at 5-10Ton/cm<2> pressure so as to be made high-density. Since the sintering temp. is regulated so that it is lower than that in the ordinary sintering, energy for joining grains is reduced and the density of the grains is increased, but the original grain boundaries are left and bonding strength is reduced. This Cu-Cr sintered compact is subjected to compression working, such as hot coining, to be formed into a near-final product shape. By the above hot compression, the sintered material is deformed in part, by which density is increased and strength is improved. In the Cu-Cr sintered material produced as mentioned above, electric conductivity is not so deteriorated and contact resistance is reduced, and merely a slight deterioration in strength is brought about.

Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration in image quality due to the deviation in GOP phases in re-encoding. SOLUTION: A bit stream (i) generated by first encoding is fed to an MPEG decoder 31, by which a decoded image is obtained. The decoded image is inputted to a frame memory 33 via a recording reproducing system 32 as a inputted decoded image. The frame memory 33 gives the inputted decoded image to an MPEG encoder 34 and an MAD calculation circuit 35 at a prescribed timing. The MAD calculation circuit 35 calculates an MAD (total sum of difference between a mean value and each pixel value). The result of the calculation is fed to a high pass filter 36, by which a separated high frequency component is fed to a B picture discrimination circuit 37. The B picture discrimination circuit 37 discriminates a picture type based on the high frequency component and gives the result of discrimination to an MPEG encoder 34.  The MPEG encoder 34 locks a GOP phase of the inputted decoded image while refer ring to the discrimination result.
