Abstract: PURPOSE: To reduce the power consumption, set the operating voltage lower than commercial power source voltage, facilitate the output control, and reduce the cost by using a new magnetron using a cold cathode as a microwave supplying source for microwave oven. CONSTITUTION: An accelerating anode 3 for imparting a high field to an electron emitting part 2 consisting of a cold cathode, and a divided anode 4 adjacent thereto are arranged in a fixed distance from the inner surface of a base 1. An output part 5 for externally emitting an electron is formed on the right end of the anode 4, and a magnet 6 is arranged so as to cover the whole working space of the electron. The connecting middle point of DC power sources Va and Vb connected in series between the base l and the anodes 3, 4 is connected to the gate of the emitting part 2, and the anode side of the power source Va is earthed.  In such a constitution, the electron emitted from the emitting part 2 is guided by a cavity resonance part in which the anode 4 is present by the magnetic field from the magnet 6, and a bunching effect is imparted thereto by the action of the electric field and the magnetic field in the working space 9. Thereafter, the electron is advanced to the right while emitting a high frequency energy.

Title: Fluorescent lamp
Inventor: HASHIMOTO NOBORU
IPC: H01J61/54
Filed: 1978-03-22
Abstract: PURPOSE: To prevent the fluorescent substance breakdown discharge between mercury grains and nesa film and prevent the pitting phenomenon, by providing recesses on the surface of the fluorescent substance.  
     CONSTITUTION: The recesses 5 are provided on the surface of the fluorescent substance 3 so that the mercury grains 4 fall into the recesses 5. Because the mercury grains 4 have a potential, they tend to gather to the recesses 5. When the mercury grains 4 have fallen into the recesses, the potential difference decreases and the discharge energy to the nesa film 2 falls. The discharge energy is reduced to such an extent as not to break down the film of the fluorescent substance 3. The pitting phenomenon is thus prevented.

Title: Slip processing system by facsimile equipment
Inventor: SATO OSAMU
IPC: G06Q10/10
Filed: 1995-01-30
Abstract: PURPOSE: To relieve the burden on an operator by transmitting both a routine slip and a non-routine slip by using the same facsimile line. CONSTITUTION: When a non-routine slip 11-2 is received and the image is transmitted to a character recognizing device 7, the character recognizing device 7 searches for a recognition mark. When the recognition mark does not exist, a detection error is generated. When this detection error is generated, a format decision part 35 segments the image of the whole slip and returns the image with the signal to the effect that a recognition can not be performed to a main controller 6. The output control part 36 of the controller 6 synthesizes the additional words to the effect that the recognition can not be performed to the image of this whole slip and outputs the image to a center fax. The operator of the center refers to the contents and the additional words and inputs transfer data, etc., by hand.  Thus, because the both the routine slip and the non-routine slip are received by the same facsimile line and are processed, the flow of the processings is simplified and a mistake can be prevented.

Abstract: PURPOSE:To allow an overflow pipe to function without hindrance by providing a water-permeable filter which is freely opened and closed to the opening at the lower end of an overflow pipe and closed only by the specified pressure exerted from the inside of the overflow pipe. CONSTITUTION:A filter 1 free to open and close is supported by a screw stopper 21 at the opening A at the lower end of an overflow pipe vertically extended from the upper part of a water feed tank directed obliquely downward to cover the opening, and a specified weight 4 is fixed to the tip of a rod 1b of specified length extended from the uppermost end of the frame 1a of the filter 1 in the opposite direction to the filter 1 through the spindle 21a of the stopper 21.
