Title: Color picture tube
Inventor: TOKITA KIYOSHI
IPC: H01J29/07
Filed: 1987-04-02
Abstract: PURPOSE:To suppress the movement of an electron beam caused by the doming by connecting a resistor between a shadow mask and a high-voltage supplying body. CONSTITUTION:A resistor 17 is electrically connected between a shadow mask 7 and a high-voltage supplying body 14. According to such a color picture tube, even if a doming phenomenon is generated by the shadow mask 7, the decelerating electric field strongly deflecting in the direction apart from the tube axis is generated near the shadow mask 7 by the voltage drop across the resistor 17. Therefore, the landing position of an electron beam to be moved in the tube axis direction from the preset landing position by the doming phenomenon is offset to be returned to the original landing position again. Accordingly, the displacement of an electron beam caused by the doming of the shadow mask can be reduced.

Filed: 1988-03-30
Abstract: PURPOSE:To obtain the compact constitution by installing two roller pairs for discharging a sheet material and a selecting means for selecting the discharge direction of the sheet material and allowing a selecting means to directly lead the sheet material into each roller pair. CONSTITUTION:The selecting operation of a flapper (selecting means) 29 is carried out by using the paper discharge trays 16a and 16b, and in case of face down, the flapper 20 introduces a sheet material into a discharge roller 15b by the edge part 20b. The edge part 20b is extended towards a driven roller 15b2 from a transport passage formed by the discharge guide member 19 (19a, 19b), and sends the sheet material directly to a discharge roller 15b. In case of face up, similarly the edge part 20a is extended towards a driven roller 15a2 from a transport passage formed by the discharge guide member 19 (19a, 19b), and sends the sheet material directly to a discharge roller 15a. Therefore, a transport passage for the sheet material after fixation can be shortened without using a needless guide member or supporting member.

Title: Facsimile signal processing circuit
Inventor: HONMA TSUTOMU
IPC: H04N1/409
Filed: 1979-06-25
Abstract: PURPOSE:To make it possible to improve picture quality by emphasizing white in black by detecting white in black in terms of an input signal before a ternary return and by giving a maximum white level near its maximum point. CONSTITUTION:Output signal 17 of DFF7 is input to monostable circuit 8 that is held at leve [H] for time(t) determined by capacitor C and variable resistor RV4. Output 18 of the circuit 8 is input from its Q terminal to the control terminal of analog gate 10, and inverted output Q'' from output 18 is supplied to the control terminal of analog gate 9. Gate 9, when signal Q' appearing at the control terminal is at [H], transmits a facsimile signal to buffer 11 and cuts off it when [L]. Further, gate 10 transmits maximum white level Vw to buffer 11 when signal Q from the control terminal, i.e., signal 18 is at [H] and cuts off Vw when [L]. Therefore, facsimile signal 19 can be obtained as the output of buffer 11 at terminal OUT before a ternary return, and emphsis is so placed that this signal 19 will be at the maximum white level.

Title: Substrate housing container
Inventor: ASANO YOSHIHIDE
IPC: H01L21/66
Filed: 1990-03-27
Abstract: PURPOSE:To prevent a substrate from slidably dropping from a substrate housing container by providing a stopper mechanism elastically pivoting to pass substrates to be pressed by the substrates when the substrates are housed and moving in an arraying direction of substrates by the force of the substrates housed therein. CONSTITUTION:When substrates 10 are housed in a substrate housing container 12, leaf springs 21e are disposed between supporting plates 11. When the springs 21e are pressed by the ends of the substrates 10, the springs 21e are bent in a direction of an arrow C at a slide rod 21c as a fulcrum to pass the substrate 10 to contain the substrate 10 in the container 12. Since a pressing force is not operated at the spring 21e passing the substrate 10, it is returned to an original position to prevent the substrate 10 contained in the container 12 from slidably dropping by the support to the plates 11. Thus, damage to a semiconductor wafer due to dropping from the container 12 is eliminated to improve the manufacturing yield of a semiconductor device.

SOLUTION: Measurements Iom , Ism and Icm are derived from a signal 50 indicative of measured intensity I(t) . At the first step 51, Fourier components S0 , S1 , S2 are calculated for a continuous and modulated pulses ω, 2ω and at the second step 52, measurements Iom , Ism and Icm are determined from the components S0 , S1 , S2 . Method of iteration 53 is applied to the measurements and initial theoretical values Is1 /Io1 and Ie1 /Io1 are derived from an input variable 55. The theoretical values obtained at Step 57 are compared with the Ism /Iom and Icm /Iom determined at Step 52. The comparison 58 requires quantization of the difference between theoretical value and measured value. When the difference is smaller than a limit value, the measurements are approximated sufficiently and a numeral 54 is provided as a physical variable for calculating the measurement.  After ending the comparison 58, an estimated value 59 following to the physical variable is specified.

Abstract: PURPOSE:To improve adhesion force between a resin and a core wire by selectively discharging only bubbles taking place around the core wire to a core wire supply side while preventing the reverse flow of the resin with provision of a recess extending, in the longitudinal direction, on a single core wire. CONSTITUTION:A recess 15 extending in the longitudinal direction is formed on a single core wire 12 by means of a core wire processing machine 18 prior to the supply of the core wire into a resin extruder 20. The extruder 20 supplies a fluorinated resin, which is a material for a foam resin layer 14, from a hopper 26 into an extruder main body 24 together with a foaming core agent such as Boronite, etc.; and injects a foaming gas into the fluorinated resin from a gas tank 30 through a constant flow pump 32. A fluorinated resin layer is supplied into a cross head 28 and is attached to the core wire 12 from a nipple, followed by extruding and coating the core wire 12 with a constant thickness through a die. The fluorinated resin is foamed by a pressure release, and the bubble appearing around the core wire 12 is discharged to the supply side of the core wire 12 through the recess 15. Consequently, the adhesive force between the core wire 12 and the layer 14 can be improved.
