Title: Improvements in or relating to television pick-up tubes
IPC: H01J29/41
Filed: 1950-04-20
Abstract: 680,153. Cathode ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. April 20, 1950 [April 25, 1949], No. 9707/50. Class 39(i) A television pick-up tube comprises a target electrode with a mosaic 3 of small photo sensitive particles on a thin continuous layer 1 of material of low electrical conductivity, the image of the picture to be transmitted being incident on the mosaic side of the target whilst the opposite side is scanned by a beam 2 of electrons which arrive thereat at substantially zero velocity, a collecting electrode 4 facing the mosaic and collecting photo electrons therefrom. The electrode 4 can be a ring or annulus as shown or it may be an optically transparent metal layer on the tube end wall giving a uniform field between the mosaic and the electrode. The film 1 is of 2-3 microns with a time constant of 1/25 second and the potential on collector 4 is never high enough to permit a secondary emission greater than 1:1. When the electrode is a transparent layer, its spacing from the target may be only a few millimetres. The target layer 1 is prepared either by inflation and rupture of a glass sphere or by anodising an aluminium plate. In the latter case the anodised plate may be introduced into another bath with reversed polarity containing copper sulphate or silver nitrate so that metal ions pass down the microscopic tubes of the alumina giving it a desired conductivity. The anodic film is detached, washed and baked, and antimony is evaporated on to it through a fine metal gauze. Alternatively the film has been given irregularities by previous sanding, hammering or grinding of the aluminium plate and antimony evaporated on at a grazing angle. Alternatively a layer of binder 1/10-1/100 microns thick of colloidal aluminium oxide or silica is deposited on the film and miscroscopic grains of antimony pulverised thereon. The antimony layer is treated in the evacuated tubes with caesium. Specifications 611,222 and 635,068 are referred to.

Patent JP-H06201121-A (JP)
Title: Controller for combustion device
Inventor: MOMODA KAZUTADA
IPC: F23N1/00
Filed: 1993-01-07
Abstract: PURPOSE:To secure the favorable combustion performance by a method wherein the rotating number of a burner fan is set so as to be lower than a rotating number corresponding to the maximum amount of combustion upon normal stabilized combustion during a period of time from the count-up of a third timer unit to the count-up of a fourth timer unit. CONSTITUTION:When the count-up of a third timer unit 15c or ignition is decided, a fourth timer unit 15d is started and a fuel pump 7 discharges fuel, corresponding to the maximum amount of combustion, until the count-up of the fourth timer unit 15d is effected while a burner fan 8 is driven with a rotating number lower than a set rotating number corresponding to the maximum amount of combustion upon normal stabilized combustion. Accordingly, the lifting of flame, which is formed on a burner head, can be prevented even when the burner unit is cold immediately after ignition whereby the production of unburnt gas and lifting sold, which is accompanied by lifting combustion, can be restricted. According to this method the stability of flame immediately after ignition is enhanced and the favorable combustion performance can be secured.

Title: Iron core for electromagnetic induction apparatus
Inventor: OMATSU TOSHIHIKO
IPC: H01F27/24
Filed: 1985-01-10
Abstract: PURPOSE:To provide a practical iron core eliminating localized over heating and having fully low loss characteristics which an amorphous magnetic member has by nature, by inserting short strips of amorphous magnetic thin plates or silicon steel plates at joint positions where magnetic thin plates of an iron core employing amorphous magnetic material are joined with each other. CONSTITUTION:An iron core 11 is formed by winding amorphous magnetic thin plates 10 which are cut preliminarily into appropriate lengthes. At joint gaps 1g, 2g,...ng from most outside to most inside of the iron core 11, short strips 13 of amorphous magnetic thin plates with the same thickness are inserted one by one. Thus since the practical iron core area is increased and disturbance of the magnetic flux is reduced owing to the magnetic thin plates 13 for the magnetic flux to be passed, localized temperature rise can be prevented. Accordingly, the iron core temperature is uniformed over all the magnetic path of the iron core to obtain better magnetic characteristics.
