Filed: 1994-02-07
Abstract: PURPOSE:To achieve quality improvement in drying of a phosphor film by providing thermal sources inside and outside the panel of a cathode-ray tube, and drying the phosphor solution applied on the inner face of the panel while controlling each heat source. CONSTITUTION:A heater 3 is arranged inside the panel 2 of a cathode-ray tube, and a heater 4 is arranged outside the panel 2, and the temperature of the heat added to the panel 2 is controlled with a controller 5. The heater 4 is divided in the direction of extension of the panel 2 into heater elements 4a, for which the temperatures can be set individually. The phosphor slurry applied on the inner face of the panel 2 is dried while controlling the temperature of the panel 2 by the heaters 3 and 4. For example, since the fringe part of the panel 2 is thicker than the center, the fringe is heated especially with the heater element 4a facing it with the control of the controller 5 so that the temperature may be equal all over the panel 2, thus the phosphor slurry applied on the inner face of the panel 2 is dried.

Abstract: PURPOSE:To obtain the internal data of a crystal such as internal stress by detecting the strain wave in a sample by a converter composed of a piezoelectric plate. CONSTITUTION:The voltages vp1, vp2 induced in piezoelectric plates 3, 4 are subtracted by a differential amplifier 5 and difference output DELTAvp is inputted to a lock amplifier 6. DC voltage vd is applied to a needle 11 by a power supply 7 and, when the needle 11 is allowed to approach the surface of a sample 1, a tunnel current (i) flows between both of them. This current (i) is detected by an ammeter 8 and the detection signal Si thereof is inputted to a servo circuit 9 which in turn outputs a drive signal Sv to operate a fine adjustment mechanism 10. By this mechanism 10, the interval between the needle 11 and the sample 1 is adjusted to keep the DC component of the current (i) constant. Further, a scanning signal Sh is outputted from a scanning circuit 12 to scan the needle 11 two-dimensionally within the plane parallel to the surface of the sample by a fine adjustment mechanism 13. Then, by displaying the signal Sv to the mechanism 10 on a display 14 in the relation with the signal Sh to the mechanism 13, a microscopic (STM) image is obtained.

Filed: 1992-02-24
Abstract: PURPOSE:To efficiently obtain routing paths in a short time by suppressing an increase in a processing time due to an increase in the number of cells to a minimum limit in an automatic routing design of an integrated circuit using a labyrinth method. CONSTITUTION:Four (2X2) cells 41 are gathered to form a composite cell 42 (d). If any of the four cells in the composite cell is not labeled in path searching, the four cells are simultaneously similarly labeled. If any of the cells in the composite cell is already labeled, the cells are individually labeled. A path between a search starting cell S11 and a target cell T12 is searched thereby to know that the composite cell indicted by shade includes a final path (b). The composite cell indicated by the shade is reversely traced thereby to obtain a routing path 31 as indicated by a dotted line (c). Thus, an increase in a processing time due to an increase in the number of the cells is suppressed to a minimum limit, and routing paths can be efficiently obtained in a short time.

Abstract: PURPOSE:To prevent the head part of receiving data from being deleted by by-passing a transmission requesting signal through a delay circuit, and obtaining a transmission allowing signal. CONSTITUTION:In a loop mode, when a carrier arrives, a carrier detecting signal CD is made active after a tCD time of the arrival for a MODEM 38. This signal CD is passed through relay contacts d4 and d2 and obtained as an active transmission requesting signal RS. Then, the signal goes through a relay contact d1 with by-passing a delay circuit 310 and goes to be an active transmission allowing signal CS. Then, the signal is sent to an AND gate 311 and a DTE2. Accordingly, the AND gate 311 goes to a passing condition when the tCD time passes after the carrier arrives at a receiving part 32B and receiving data RD are detected in the receiving part 32B and passed through relay contacts d5 and d4. When the data arrives as transmitting data SD, the data are passed through. Thus, the data are prevented from being deleted in the head part.

Abstract: PROBLEM TO BE SOLVED: To improve performance of steering stability at running time on a wet road surface. SOLUTION: A sipe 20, comprising a central part sipe 22 of hexagonal shape consisting of a first part 22A and a second part 22B forming a small block 21 independent of the periphery and a peripheral part sipe 24 branching from tire width direction both end parts of this central part sipe 22 to be connected to a peripheral direction groove, is formed, in a block 18. The central part sipe 22 of closed loop shape is provided in a central part of the block 18, sipe density of the block central part is increased, so as to absorb a large amount of water in a grounded surface at running time on a wet road surface. Absorbed water is efficiently drained to the peripheral direction groove through the peripheral part sipe 24.  Since the sipe 20 is shallower and thinner than the central part sipe 22, high performance of driving stability at running time on a wet road surface is obtained without decreasing rigidity of the block 18.
