IPC: B65H65/00
Filed: 1989-12-18
Abstract: PURPOSE:To easily take out a tail end even in the after-handling process by dropping down the tail end of a package from a thread-layer along the end face of the package, and traversing the tail end across the end face of the package, and thereafter returning it on the thread-layer.

IPC: F24F13/22
Filed: 1990-11-30
Abstract: PURPOSE:To remove the float in a water receiving vessel and provide a stable device to stop filling to full of water by providing a metal plate in the water receiving vessel and sensing an increase in the electrostatic capacity between the metal plate and the dehumidification water to stop automatically the operation of a dehumidifier. CONSTITUTION:A dehumidifier sucks air from an air suction port 1, and when the air goes through a cooler 4, its temperature drops below the dew point temperature and condensate on a cooler 4, and the dehumidification water is led to a removable water receiving vessel 8 that is arranged below the dew receiving pan 7. As the time passes the water level rises. The fact that the water level reaches a specified water level is sensed by the increase in the electrostatic capacity between the metal plate 9 and the dehumidification water. Two pieces of metal plates are arranged perpendicularly to the water face, and the difference in electrostatic capacity between the metal plate and the earth is kept below a specified value. As the water face of the dehumidification water increases and rises, the electrostatic capacity between the metal plate 12 on the lower side and the earth through water becomes very large, and there is a large difference between this capacity and the electrostatic capacity between the upper metal plate 13 and the earth. When the difference of the electrostatic capacities becomes larger than a specified value, a stop signal is issued and the operation of the dehumidifier is stopped.

Title: Lighting device for high pressure electric discharge lamp
Inventor: YAMAMOTO MINORU
IPC: H05B41/18
Filed: 1991-12-13
Abstract: PURPOSE:To provide a lighting device with simple constitution and prevent self-maintaining discharge of the discharge gap of an ignitor portion which is operated through the outputs of an inverter circuit. CONSTITUTION:The output of an inverter circuit comprising switching elements Q1-Q4 is supplied to a booster circuit 1 as power supply via a diode D5. Because rectangular wave voltages at both ends between (a) and (b) are rectified at the start of a lighting device, voltage at (c) point becomes half-rectangular-wave voltage. An ignitor portion IGN is operated only during the positive period and if during this period both-end voltage, i.e., electric charge stored in a capacitor C2 reaches discharge starting voltage, a discharge gap GAP discharges. High-pressure pulse voltage is generated on the secondary side of a pulse transformer PT and is applied to a lamp L. At this time, even if there is self- maintaining discharge in the discharge gap GAP, the self-maintaining discharge of the discharge gap GAP is stopped since the action of the ignitor portion IGN is also stopped during the period in which power supply to the booster circuit 1 is stopped.

Abstract: PURPOSE:To discriminate an alarm device emitting an alarm and to discriminate whether it is an alarm at the time of an alarm cause pursuit or an alarm to preserve the previous one by restoring to an original condition after running an indication means for a previously prescribed time when a signal comes from an alarm decision circuit. CONSTITUTION:A title device is provided with a time limit timer output circuit 3 to output a signal only for a previously prescribed time (a) when a signal from an alarm decision circuit 2 is inputted, a flashing timer circuit 4 which is constantly in a successive outputting condition, once it has an input, the pulse signal of a short cycle only for a previously prescribed time (b) from the time of the input, generates a successive output until a next input comes, and normally a>b. Thus, since the alarm device flashes or rumbles for the time (b) from the alarm device emits the alarm and successively lights on or keeps rumbling after the lapse of time (b) from the time emitting the alarm until the time (a), the alarm device emitting the alarm can be discriminated.

Filed: 1992-12-10
Abstract: PURPOSE:To allow the detection of the variation of DC voltage produced from an AC/DC converter with no time lag. CONSTITUTION:Output voltage from a thyristor converter 1 is converted by a V/F converter 3 into frequency and pulse signals based on the frequency are counted through a counter 4 thus obtaining a count value Cn. A measuring time T is then determined based on a measuring time count value tn counted by a counter 5 and a clock period t0 for measuring time. The count value Cn is then divided by the measuring time T thus operating a DC output voltage X quickly.
