Title: Display device using multicolor cathode ray tube
Inventor: TERAKAWA TOSHIAKI
IPC: H04N9/20
Filed: 1980-06-06
Abstract: PURPOSE:To reduce the distortion of display due to excessive radiated current, by making different the amount of radiated current to a fluorescent substance layer according to the number of displayed colors. CONSTITUTION:In case of monochromatic specification, for example, when a video signal is produced from a red signal generator 1, the output of an inverter I1 is low, the emitter potential of a TRQ1 is lowered and electron beams are radiated from the cathode coupled with a terminal T1. In case of two colors, for example, in case of red and green display, the outputs of inverters I1 and I2 are low, the potentials of the emitter of TRs Q1, Q2 are lowered via resistors R71, R72, the input to an NAND circuit N2 is high and the output is low, and the output of an inverter I5 is high. Further, since the outputs of NAND circuits N3, N4 are high, the output of inverters I3, I4 are low. Thus, a parallel resistance network consisting of R41, R61, R71 is formed to the TRQ1 and the potential of the cathode is decided. Thus, the increase in the amount of electronic beam can be controlled according to the increase in the colors to be displayed.

Filed: 1989-03-30
Abstract: PURPOSE:To prevent the occurrence of the positional deviation of a tape at the time of repeating the operation for unloading or loading and to prevent the recorded information from being erased erroneously by controlling the rotation of a driving means on the bases of the detection signal outputted from a detecting means. CONSTITUTION:At the time of unloading a magnetic tape 4, when the necessary quantity for taking up the tape on one take-up reel 3 is reduced as the unloading closes to the end, the magnetic tape 4 is supplied from the other supplying reel 2, and then, the supplying reel 2 begins to rotate. At this time, the rotation of the reel is detected by the detecting means 10 and the detection signal is outputted to a control means 11 and the detection signal is received by the control means 11 and then, the rotation of the reel driving means 9 is performed at low speed or at low torque by the control means. Consequently, the tape taking-up quantity of the reel 3 is reduced and the tape quantity supplied from the other reel 2 can be reduced and nearly fixed. Thus, the positional deviation of the tape can be reduced at the time when the operation for unloading or loading is performed.

Title: Controller for burner
Inventor: OGUCHI YUKIHIRO
IPC: F23N5/24
Filed: 1989-03-29
Abstract: PURPOSE:To perform countermeasure against abnormal combustion that may occur prior to the actuation of a controller by providing a reset diode extending from the charging line of a capacitor toward an output from a delay timer. CONSTITUTION:Since an output from a delay timer 13 is connected with a reset diode 14 of a capacitor 6, and capacitor 6 generates quick discharge and an output from a voltage detecting inverter 8 becomes H when the output from the delay timer 13 changes from H to L. However, a low-flame sensor 2 detects flame by that time and retains an input into an NOR circuit to be L, so that the combustion can be continued. When the low-flame sensor 2 detects no flame during the operation of combustion, safety means 4 is immediately actuated. According to this method, even the state of a trouble where flame becomes abnormally large immediately after ignition can be corrected sufficiently.

IPC: G02F1/13357
Filed: 1992-03-31
Abstract: PURPOSE:To provide a liquid crystal display device preventing moire caused by the nonuniformity of brightness generated on the irradiation face. CONSTITUTION:When fluorescent lamps 14 are lit up, a first prism body 21 changes the direction of irradiation light from the approximately 0 deg. direction toward an irradiation opening part 13 in the approximately 0 deg. direction, and a second prism body 23 transmits irradiation light from the approximately 0 deg. direction to this second prism body 23 and totally reflects irradiation light from the direction other than the 0 deg. direction. That is, the direct light from the fluorescent lamps 14 and the oblique irradiation light radiated from the first prism body 21 are thereby reflected, and only the irradiation light reflected in the 0 direction by the first prism body 21 is transmitted. The apparent luminescence face is formed on a light diffuse transmission member 25, and it is hard to generate the nonuniformity of light on this light diffuse transmission member 25. A liquid crystal body 26 is thereby irradiated by uniform irradiation light from the back face, so that the nonuniformity of light can be prevented.
