Title: Short arc welding method
Inventor: FUJIMURA HIROSHI
IPC: B23K9/16
Filed: 1984-03-07
Abstract: PURPOSE:To improve stability of welding arc by detecting electrically short circuiting and separation of a droplet then controlling the varying intensity of welding current and controlling high and low wire feed speeds, the intermission of wire feeding, forward and backward revolutions, etc. CONSTITUTION:A voltage decider 11 judges the short circuiting or separation of a molten metal from the information obtd. by a voltage detector 14 and outputs the signals corresponding respectively therewith to a motor controller 8 and a power source controller 12 in the stage of welding. The controller 8, triggered by the signal from the decider 11, controls the acceleration and deceleration of rotating speed of a motor 8 driving a feed roller 7 as well as the start, stop, forward revolution and backward revolution thereof according to the time set in a time setter 13. The controller 12, triggered by the signal from the decider 11, controls likewise a power source 9 to control the varying intensity of the welding current. The arc stability of short arc welding is thus improved.

Title: Doping method
Inventor: OKUMURA FUJIO
IPC: H01L21/225
Filed: 1987-02-24
Abstract: PURPOSE:To facilitate satisfactory impurity doping and avoid a harmful influence upon other elements and wirings by a method wherein an amorphous silicon film is formed on a semiconductor material and a laser beam is applied to the amorphous silicon film from the above to raise the temperatures of the amorphous silicon film and the semiconductor material and to dope the semiconductor material with an impurity. CONSTITUTION:An amorphous silicon film 2 containing an impurity such as boron or phosphorus is formed on a semiconductor material. A laser beam 3 is applied to the amorphous silicon film 2 from the above to raise the temperatures of the amorphous silicon film 3 and the semiconductor material and to dope the semiconductor material with the impurity. In other words, the laser beam 3 is particularly absorbed in the part of the amorphous silicon film 2 and that part is melted first. Also the surface of the silicon wafer 1 is melted by the heat and the melted part is doped with P in the amorphous silicon film 2. The advantage of this doping method is that the amorphous silicon which facilitates lowering of the energy density of a laser has a ten times larger absorption coefficient than single crystal silicon even in the wavelength range of an excimer laser and the most part of the light beam is absorbed in a very shallow part so that the energy density required for melting can be low. With this constitution, damages given to the other elements and wirings between the elements can be reduced substantially.

Title: Magnetic head
Inventor: HARA TOSHITAKA
IPC: G11B21/21
Filed: 1987-02-25
Abstract: PURPOSE:To obtain a stable output, and further, to prevent the attraction of a magnetic head to a magnetic recording disk, even if the floating-up quantity of the magnetic head is micronized by giving a groove to a slider surface so that its surface roughness comes to be 0.005-0.02mum. CONSTITUTION:The groove is given to the surface of the slider 2 of the magnetic head 1 by a lapping tape, in a direction that the magnetic recording disk 9 passes through at the time of a rotation. The surface roughness is made to be within the range of 0.005-0.02mum. When it is <=0.005mum, an effect to prevent the attraction of the magnetic head 1 to the magnetic recording disk 9 is not enough, and when it is >=0.02mum, a friction between the slider 2 and the magnetic recording disk 9 at the time of a starting and a stopping comes large. Thus, because a distance between a magnetic substance thin film 7 and the magnetic head 1 can be kept constant, the stable output can be obtained even if the floating-up quantity is micronized, and a high density recording is possible.

Abstract: PROBLEM TO BE SOLVED: To provide a digital broadcasting receiver provided with a data source capable of improving the efficiency of various processings by checking whether or not respective channels are turned to a descrambling inhibition state and preparing a database for the channels not turned to the descrambling inhibition state. SOLUTION: An NIT (network information table) is received and service-ids (channel numbers) are listed up. The listed-up service-ids are received one by one and whether or not the channel is descramblable is judged (S88). For the judgement, when a key for descrambling can be obtained from an IC card mounted to a receiver main body, descrambling is possible. The service-id of the channel judged as descramblable is preserved in a memory (S90). In the memory, the database for the channel not in the descrambling inhibition state is preserved.

Abstract: PURPOSE:To obtain a liq. crystal display device with enhanced durability and reliability, by irradiating far ultraviolet rays having a specified wavelength or below on orienting films on the surfaces of glass substrates at the peripheral sealing parts to enhance the tightly sealing performance of a sealing resin. CONSTITUTION:Far ultraviolet rays having <=250nm wavelengths are irradiated on a liq. crystal orienting agent on the surfaces of a pair of opposite glass substrates at the peripheral sealing parts to which a sealing resin is stuck. The  lamp of an ultraviolet irradiator to be used is an ozone genertion type lamp  emitting light having <=about 200nm wavelengths, and a conventional ozoneless  type lamp which is used in the ultraviolet curing of resin, etc. is not effective.

Title: Production of bulk material by vapor phase depositing method
Inventor: NANBA HIROKUNI
IPC: C01B19/04
Filed: 1980-04-04
Abstract: PURPOSE: To prevent cracking of deposits and make peeling from substrates easy by depositing bulk material on the buffer layer on the substrate which has no reactivity with the deposit and has good peeling property.  
     CONSTITUTION: The graphite substrate 7a of the substrate 7 in a reaction chamber 1 has a buffer layer 7b of about 5W100μm. The inside of the chamber 1 is evacuated through an exhaust pipe 4 via a cold trap 5 and is heated with a heating furnace 2, thence a gaseous raw material 3 is supplied to allow deposit 6 to deposit, thence it is cooled. At this time, the binding strength between the deposit 6 and the substrate 7 decreases and the slipping of the substrate surface improves, thus the friction between both decreases. As a result, no cracks are produced in the deposit 6 at  the cooling and the peeling thereof is accomplished easily. In this case, the peeling property of the layer 7b may be either of the interface with the deposit 6 or the interface with the graphite substrate 7a.

Abstract: PURPOSE:To prevent a time delay up to the execution of communication processing by giving the permission of starting communication of a control signal by a control radio channel (C-ch) and communication by a talking radio channel (S-ch) to only one station in base stations being component of a same communication zone and revising the base station giving the permission sequentially among the base stations. CONSTITUTION:The permission of communication of a control signal through a C-ch in same communication zones 4a-4j comprising plural base stations 2a-2c and the permission of starting the communication through an S-ch are given at most to only one station of the base stations 2a-2c in the communication zones 4a-4j. Then the base stations 2a-2c receiving the permission are changed sequentially among the base stations 2a-2c in the same communication zones 4a-4j. Thus, a useless position registration reply due to a difference between a base station identification code stored in the mobile station 6 and the base station identification code included in a signal on an outgoing channel of a C-ch and a non-response to a signal for the communication processing are prevented and the collision of C-ch channels caused because the plural base stations 2a-2c exist in the same communication zones 4a-4j is prevented.
