Title: Grid-bias controlling method for image tube
Inventor: JIYON BARETSUTO JIYOOJI
IPC: H04N3/20
Filed: 1992-02-28
Abstract: PURPOSE: To provide a grid cut-off bias with a long cut-off time constant. CONSTITUTION: A switching supply voltage is fed to voltage division devices 54, 55 and given an output terminal 52 via a capacitor 53. A divider output tap 57 is connected to the output terminal via a conduction path of a common base transistor(TR) 60. (1) The TR is operated in the inverting mode to charge the capacitor 53 at first, (2) is in operation in the normal or the inverting mode for a current supplied to the output terminal in any direction to adjust a grid bias voltage at the output terminal, (3) is in operation in the separate mode when the applied voltage is lost so that the capacitor 53 provides an output of a negative grid cut-off bias to the output. The TR 60 blocks discharge of the capacitor 53. Since no discharge path other than a leakage path is in existence, the cut-off time constant is extended.

Title: Washing method for semiconductor wafer with pure water
Inventor: WATANABE MITSURU
IPC: B08B3/02
Filed: 1987-04-02
Abstract: PURPOSE:To decrease the amount in the use of pure water, to improve the effect of washing in a short time and to reduce the amount of chemical, which is put into an automatic pure- water replacing bath, to a minute value, by taking a wafer carrier out of a chemical treating bath, removing the chemical by washing with pure water spraying, and immersing and washing the wafer carrier in the automatic pure water replacing bath. CONSTITUTION:A wafer carrier 20 is immersed and treated in a chemical treating bath 11 for a specified time. Thereafter, the wafer carrier 20 is held with a conveying robot hand 22 and lifted out of the treating bath 11. Then the wafer carrier 20 is moved to a pure-water spraying washing bath 12 at first and then lowered into the specified position in the washing bath 12. At this time, pure water is jetted through a pure-water spraying nozzle 13, and the chemical attached to the wafer carrier 20 and semiconductor wafers 21 is removed. Since the most amount of the chemical, which is attached to the wafers and the wafer carriers, is removed with the washing with the first spraying of the pure water, the wafers and the carrier are sufficiently cleaned when they are immersed and washed in an automatic pure- water replacing bath 14 twice. The chemical, which is brought into the next automatic pure water replacing bath, becomes of a minute amount by the first washing with the spraying with the pure water.

Filed: 1995-04-05
Abstract: PURPOSE: To secure the junctioning accuracy stably and improve the productivity by inserting a waxed foil which is previously cut to a specified position between a wavy foil and a plain foil, each time each layer is formed in a diametral direction, when a cylindrical honeycomb form is manufactured by arranging the waxed foil between the wavy foil and the plain foil and winding these foils around a take-up shaft in a spiral fashion. CONSTITUTION: When manufacturing a honeycomb form 4 which is used a catalyst carrier for an electric heating catalytic device, a wavy foil 3 and a plain foil 2 are wound by rotating a take-up shaft 1 to prepare a cylindrical honeycomb form 4. In this case, waxed foils 5a, 5b which are cut respectively at points A and B every time when foil layer is formed in a diametral direction. That is, a waxed foil introduction angle is previously set to a total number of windings + angle (e.g. <360 deg.), then the wavy foil 3 and the plain foil 2 are wound in a stacked state, detecting the total number of windings and the angle from an original point, and the waxed foils 5a, 5b are inserted into a space between the wavy foil 3 and the plain foil 2, if a set total number of windings and angle are reached.  Thus, it is possible to positively arrange each junction part which can be energized at its related set position.

Title: Electronic machinery
Inventor: URAMOTO YUUJI
IPC: G06F1/24
Filed: 1981-05-26
Abstract: PURPOSE:To prevent the malfunction of a printer and at the same time to keep a high printing grade, by supplying the auto-clear signal to the main body of an electronic machinery when a power supply is switched. CONSTITUTION:A power supply is applied between the terminals 2 and 4 when a dry cell is used, and the output of a transistor TR is set at a low level since the TR is off. Then an AC adaptor is inserted to apply the power supply between the terminals 2 and 3. Thus the TR is turned on, and the output of the TR is changed to a high level from a low level. As a result, an OS1 works to apply the one-shot and to supply the auto-clear signal ACL to a CPU via an OR circuit. The TR is turned off by pulling out the AC adaptor, and accordingly the output of the TR is set at a low level. Then an OS2 works to supply the signal ACL to the CPU via the OR circuit. As a result, the CPU resets an internal register. Thus the malfunction of a printer or the damage by burning of a thermal head can be prevented to keep a high printing grade.

Title: Corrosion protection method of internal surface of steel pipe
Inventor: TOU SHIYUNICHI
IPC: E02D31/06
Filed: 1994-03-29
Abstract: PURPOSE:To prevent corrosion of the internal surface of a steel pipe in a marine steel structure having steel pipe structure by sealing sea water, a deoxidizer and a flotation agent into the steel pipe from a filler hole formed to the upper section of the steel pipe and hermetically sealing the filler hole. CONSTITUTION:A steel-pipe upper cover 5 is fixed onto a steel-pipe pile body 4, the inside of which is hollowed, by welding a filler hole 2 is formed to the cover 5, and a female screw mounted to the cover 5 is screwed to a male screw fitted outside the filler hole 2. Sea water 6 is housed up to approximately half height from the filler hole 2, a deoxidizer consisting of iron powder and a flotation agent composed of sawdust are stored in a steel pipe pile 3, a cover 7 is screwed to the filler hole 2, and the cover 7 is closed. The flotation agent functions as the keeping of metal powder at a place (a water surface), where the internal surface of a steel pipe 1 is easy to be corroded. The deoxidizer bonds with oxygen in air and in water, and oxygen required for corroding the steel pipe 1 is wasted, thus inhibiting corrosion in the steel pipe 1. Accordingly, the internal surface of the steel pipe 1 can be protected against corrosion by a simple means.
