Abstract: PURPOSE:To improve a shelf life at a high temp. after recording by providing a recording layer consisting of a resin having a specific structure and a quencher on a substrate. CONSTITUTION:A recording layer consists of a resin having a cyanine dye having an indole ring at the side chain and a quencher. The cyanine dye is expressed by the formula PHI-L=PSI(X<->)m, in which PSI and PHI denote an indole ring which may be condensated with an aromatic ring, for example, benzene ring, phenanthrene ring, etc., and PHI and PSI are usually the same. L denotes a connecting group for forming a mono-, di-, tri or tetracarbocyanine dye. X<-> is anion and m is 0 or 1. The resin is enumerated by an OH-contg. resin, COOH or acid chloride group-contg. resin and NH2-contg. resin. The resin and the dye are bound by direct condensation or condensation with the other connecting component. The quencher is particularly preferably a singlet oxygen quencher and is incorporated at generally 0.05-12mol, more particularly 0.1-1.2mol in 1mol the cyanine dye in the dye-bound resin. The thickness of the recording layer is made usually about 0.03-10mum.

Title: Hearth-roll for heat treatment
Inventor: SEKIYA BUICHI
IPC: C21D1/00
Filed: 1979-05-22
Abstract: PURPOSE:To prevent the formation of scale build up on the surface of a hearth roll for heat treatment, by forming chromium oxide layer on the surface of the base material of the roll by spraying. CONSTITUTION:A hearth-roll for heat treatment is made by using heat resistant cast steel as a base material, and Cr2O3 layer is formed on the surface of the roll by spraying Cr2O3 powder as spraying material by means of a plasma jet machine. Cr2O3 melts at 1,990 deg.C, is excellent in heat resistance, hardness, and wear resistance, and hardly reacts with acid and alkali. Hence the Cr2O3 layer on the roll surface scarcely reacts with scale components such as FeO, SiO2, MnO etc., consequently no deterioration is caused in the quality of steel plate having been rolled with the roll due to the formation of scale build up.

Title: Magnetron
Inventor: KUME MASAHIRO
IPC: H01J23/20
Filed: 1982-04-16
Abstract: PURPOSE:To increase the performance of a magnetron by decreasing the difference between the amplitudes of the high-frequency electric fields of vanes seen from a cathode by setting the distances between the cathode and the upper or lower ends of the free ends of the vanes so that the distances between the cathode and parts of the vanes to which outer straps are connected are shorter than the distances between the cathode and parts of the vanes to which inner straps are connected. CONSTITUTION:A tapered section 31 is provided at the lower end of the free end of a vane 30. As indicated in Fig. (b), a tapered section 41 is provided at the upper end of a vane 40. In any case, the distances (l1) and (l2) between a cathode 11 and the upper or lower ends of the free ends of the vanes 30 and 40 are set so that the distances between the cathode 11 and inner straps 15c and 15b connected to the vanes 30 and 40 are larger than the distances between the cathode 11 and other straps 15a and 15d connected to the vanes 30 and 40. Owing to the above constitution, the difference between the amplitudes of the high-frequency electric fields of the vanes 30 and 40 which are adjacent to each other at their ends, can be removed by controlling the distances between the cathode 11 and the vanes 30 and 40. As a result, the performance of a magnetron can be increased by preventing any vibrations to the cathode 11.

Filed: 1979-05-24
Abstract: PURPOSE: To improve bonding property and oxidation resistance by adding the specific amounts of Ga or In along or both to the base soft braze material composed primarily of Pb or Sn.  
     CONSTITUTION: Ga 10W100ppm or In 300W5,000ppm alone or both are added to the base soft braze material of Pb-Sn alloy or Pb-Sn-Ag alloy. It is for the purpose of assuring oxidation resistance and spreading rate that the addition amount of Ga is made 100ppm or more and it is for the purpose of preventing the hindrance of bonding reactivity at the bonding and melting that it is made 100ppm or less. Similarly in the case of In, the oxidation resistance and spreading rate cannot be secured at not more than the specified amount and the bonding reactivity is hampered at not less than the specified amount.

Title: Phase synchronizing signal generating circuit
Inventor: KASHIWABARA ATSUSHI
IPC: H03K5/00
Filed: 1991-03-28
Abstract: PURPOSE:To obtain an accurate synchronizing clock despite a long trigger cycle by generating a comparing reference wave based on a reference clock and defining the digital value of the voltage level of the comparing reference wave set in an input state of a trigger signal as the reference voltage. CONSTITUTION:A triangular wave generating circuit 2 generates a comparing reference wave based on a reference clock received from a crystal oscillator 1. When a trigger signal TRG is inputted, a sample holding circuit 3 immediately holds the voltage level of a triangualar wave set at the input of the signal TRG. At the same time, the held voltage undergoes the digital conversion through an A/D converter 5 and latched by a latch 6. Then the digital value of the latch 6 is converted again into an analog signal by a D/A converter 8 and compared with the triangular signal of the circuit 2 by an analog comparator 4. The comparator 4 outputs a signal when the level of the triangular wave signal is higher than the analog signal. Therefore the output signal of the comparator 4 is turned into a clock signal CLK that is accurately synchronous with the signal TRG.

Since the anilox roller 13 is cut off from the gear 15 of the anilox roller by the first shiftable clutch 30, the anilox roller 13 is driven at a low continuous operation rotational speed during the stop period of a main drive device. At a time of cleaning work, the anilox roller is driven in a reverse direction at a rotational speed higher than that at a time of printing work through the motor 31.
