Title: Base drive circuit for transistor
Inventor: ISHIBASHI HIDEAKI
IPC: H03K17/04
Filed: 1985-10-15
Abstract: PURPOSE:To obtain a reverse bias power supply of each stage from a low voltage winding with a tap by connecting a reverse bias power supply of a pre-stage transistor (TR) to a base of a post-stage TR in a Darlington TR circuit with compensation power supply. CONSTITUTION:Compensation power supplies (3a-3c) to compensate the collector loss and making a collector-emitter voltage saturated are connected to an emitter of the pre-stage TR 2 in Darlington connection and a reverse bias power supply to speed up the turn-off of TRs 1, 2 of each stage is connected to base-emitter. The reverse bias power supply is obtained by a center-tapped low voltage winding 7c of a transformer 10 and diodes 7a, 7b, 13a, 13b and since the low voltage winding is used in common, the circuit is simplified. Further, since the compensation power supply is connected in series with the reverse bias power supply and a sufficient reverse bias current flows until the pre-stage TR 2 is turned off, no trouble is caused.

Title: Formation of oxynitride film
Inventor: SHIOTANI YOSHIMI
IPC: H01L21/318
Filed: 1987-09-10
Abstract: PURPOSE:To make it possible to form a film having precise and uniform thickness on a silicon substrate by means of a lamp annealing apparatus, by employing ammonia and oxygen as reaction gases and substituting these gases with each other while continuously changing proportions of flow rates thereof. CONSTITUTION:A silicon substrate 1 is introduced in a lamp annealing apparatus and disposed on pins 4a of a carrying base 4. Nitrogen gas is then introduced into the lamp annealing apparatus and the temperature within the apparatus is increased to a lamp annealing temperature, With the lapse of treating time, proportion of the nitrogen gas in the introduced gas is decreased gradually while proportion of ammnonia is increased by that much, until all of the introduced gas is occupied by ammonia. Treatment is performed under such conditions so that a silicon nitride film 2 is formed on the surface of the substrate 1. After that, the proportion of ammonia is decreased while the proportion of oxygen gas is increased by that much until all of the introduced gas is occupied by oxygen gas. Treatment is performed within the atmosphere of oxygen so that the silicon nitride film 2 formed with ammonia is converted into an oxynitride film 3. The oxygen gas is then substituted with nitrogen gas and the silicon substrate 1 is taken out of the apparatus.

Filed: 1992-08-03
Abstract: PURPOSE:To provide a detector so designed that, during detecting the presence/ absence of weft by contact of filler finger electrodes, an air jet is sprayed against the electrodes to assure weft to come into contact with the electrodes and prevent weft misdetection. CONSTITUTION:In a water jet loom, a weft 12 is picked into the opening for a warp 10 by a picking device followed by beating up; at this time, a filler head 20 is rocked in an unit with a reed 14 to bring a pair of the electrodes 25, 27 of filler fingers 24, 26 into contact with the weft 12 to detect its presence/ absence. In this case, an air jet is sprayed from the main nozzle 32 of an intermitted spray device 30 against the electrodes; the air jet then passes through the vent holes of the filler fingers and is put to suction by a suction device, thus assuring the above contact. At the same time, the weft 12 is imparted with a tension in the picking direction by an air jet in such direction from a subnozzle 34 to avoid disturbance at the tip of the weft 12 due to its backtwisting to further assure the above contact, thus preventing occurrence of weft misdetection.
