Title: Surface hardening build up welding
Inventor: NOTOMI HIROSHI
IPC: B23K9/04
Filed: 1984-11-08
Abstract: PURPOSE:To form wear resisting weld metal free from defects containing SiC on the surface of a base metal by feeding powder of SiC or SiC and Al or Al alloy into the arc between Al alloy base metal shielded by inert gas and a non-consumable electrode. CONSTITUTION:When the circuit of the first DC welding power source 8 is closed while supplying argon gas 10, a pilot arc is generated between the tip of an electrode 2 and the tip of a copper electrode 4. When the circuit of the second DC welding power source 9 is closed while supplying argon gas 11, a plasma arc is generated between the electrode 2 and an Al alloy base metal 1. After adjusting the current and voltage, specified proportion of SiC powder is fed into the plasma arc. Then, particles of SiC enter a molten pool of molten Al alloy base metal 1 and particles of SiC are uniformly dispersed in molten metal due to stirring effect of the molten pool. This is because the density of SiC is near the density of Al alloy, and temperature of decomposition of SiC is much higher than melting point of Al alloy and does not react with the molten metal. The surface of the molten metal thus obtained is smooth and free from cracks.

Abstract: PURPOSE:To reduce dropouts that tend to occur at the time of searching of a wideband disk by constituting the titled device in such a manner that when the disk is in the search mode, it is detected to further modify the characteristic of an RF equalizer to that for conventional disk. CONSTITUTION:The circuit constitution of the RF equalizer circuit differs from that of a conventional RF equalizer circuit; resistors R10-R12 as well as an NPN transistor Q4 are additionally used in connection. An identification signal recorded in a wideband disk together with an information signal is supplied to a disk identification part 12 where it is identified and detected, and a control signal is outputted to a control signal generation part 13 from the part 12. The transistor Q4 whose base is connected to the part 12 via the resistor R12 is turned on, and the frequency band is expanded through the resistor R11, while the resistor R10 is given a considerably large value of resistance in order to reduce the collector capacity of the transistor R4. As a result, both of conventional disk or wideband disk are excellently reproduced.

Title: Remote typewriter printing system for power system information
Inventor: KOBAYASHI YOSHIYASU
IPC: H02J13/00
Filed: 1993-09-24
Abstract: PURPOSE:To prevent the duplicate printing of the same information before printing is made to a remote typewriter by providing a same information detection means to the system. CONSTITUTION:When a state of an equipment 4 covered in duplicate by monitor ranges 2, 3 of computer systems A, B is changed, the systems A, B detect the state change and output state change information to a remote typewriter 16 via a packet network 11. A same information detection means 14 obtains the occurrence time of new reception information and searches the information of preceding and succeeding schedule time as to typewriter print information arranged in time series to discriminate whether or not the same information has already been received based on a sole code with respect to an object installation system and the direction of the state change. When the information is the same, no printing is made. When the same information having been already printed is detected, it is not noticed of the operator but it is stored in a file together with the printed information for future retrieval of the information. The file is provided to the same information detection means 14. Should different information be discriminated to be the same, since the information is left, it is checked later. Thus, the duplicate print of the same information is prevented.

Title: Optical disk
Inventor: KINOSHITA YOSHIO
IPC: G11B7/24
Filed: 1993-09-24
Abstract: PURPOSE:To prohibit erasing and alteration of once recorded data by changing the reflectivity of both of pit forming parts and non-pit forming parts at the time of writing so that the temp. of s recording film do not rise up to a pit forming temp. at the time of the next irradiation with a writing laser beam.

Title: Data recording system
Inventor: DOI TAKASHI
IPC: G06F3/06
Filed: 1984-11-10
Abstract: PURPOSE:To reduce significantly the retrieval time of non-written area by deciding whether the non-written area is a defective one and to take an alternate area, or it is a simply non-written one and referring to a high speed memory device so as to write data. CONSTITUTION:Assuming that an unwritable block A on one track arises in a user area, the alternate area is accessed to write data to be written in the initial sector of the block A in a blank area. Simultaneously, the ID in the block A is written in the initial blank sector of an ID recording area and also in an IC memory 5 built-in an optical disk controller 4. Accordingly the optical disk controller 4 can control the ID of an unwritable block arising during a write action in its memory 5. Namely, when a non-written block is detected at the time of reading information on the user area, the decision can be made in a short period whether the non-written block is merely not used, or it is an unwrittable block by accessing a table in the memory 5.

Title: Gate turn off thyrister
Inventor: SATO YUKIMASA
IPC: H01L29/744
Filed: 1989-09-14
Abstract: PURPOSE:To improve switching operation by forming an anode short circuit layer of concentric circle only inside a part wherein a region among arrangement rings by a number of N-emitters is projected to the anode side. CONSTITUTION:An anode short circuit layer is provided not only between adjacent N-emitters (width d) but also in the central part and an outer peripheral part of a semiconductor substrate 1. The width d1 of an anode short circuit layer 11 in the central part, the width d2 of an anode short circuit layer 12 at the outer peripheral part, and the width d of a short circuit layer between N-emitter arrangement rings are set to at least a size of a carrier diffusion length d3 inside an N-base layer 4. A flow of a carrier enlarges transversely by about a diffusion length d3 during conduction of GTO. Therefore, if the width of each anode short circuit layer is set to at least the width of the carrier diffusion layer d3, intensity of short circuit can be made constant. Furthermore, the intensity of short circuit between the innermost peripheral arrangement ring and the outermost peripheral arrangement ring can be made the same as that of the arrangement ring which is held between said rings by providing anode short circuit layers 11, 12. Uniformity of operation of GTO can be improved in this way.
