Title: Optical disk device
Inventor: NAKAYAMA MASAHIKO
IPC: G11B11/105
Filed: 1993-11-20
Abstract: PURPOSE:To reduce the size and cost of the device by tracking an objective lens by a differential signal from pregrooves and driving a carriage by the differential signal from a mirror surface part. CONSTITUTION:The reflected signal from the pregrooves 6a is received by bisected photodetectors 8 and the objective lens is driven by the differential signal of the two signals obtd. from the photodetectors 8a, 8b. The reflected light from a mirror finished part 6b is similarly received by the bisected photodetectors 8 and the carriage 30 supporting the objective lens 5 is driven by the differential signal thereof. The objective lens 5 is driven when the reflected light quantity from an optical disk 6 is below a specified level and the carriage 30 is driven when this quantity is above the prescribed level. Then, the need for a means for detecting the position of the objective lens disposed at the actuator so far is eliminated and the size and cost of the device are reduced. Since this device is of a type to move only a part of the optical device including the objective lens 5 and the reflection mirror 21, the pickup capable of dealing with high-speed access is obtd.

Title: Memory access controller
Inventor: ENATSU NORIRO
IPC: G06F12/06
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To reduce unnecessary power consumption by preventing addresses and data to be accessed from being inputted to all memory blocks, and to reduce a chip area by shortening a decoding time in each memory block. SOLUTION: Only the upper bits of an address to be accessed are decoded, and a memory block to be made active is designated. Therefore, only a low order address is inputted as an address to be applied to the memory block so that a processing speed can be quickened. Also, only the specific memory block is activated so that charging and discharging currents can be suppressed, and that power consumption can be reduced. Moreover, the upper bits of the address decoders which are conventionally owned by all memory blocks are processed by one decoder in a batch so that only the address decoder of the lower bits can be constituted at the memory block side, and that a chip area can be reduced.

IPC: F23D14/14
Filed: 1994-12-20
Abstract: PURPOSE: To hold stable flames and prevent fire from being put off and eliminate the generation of an ignition failure even if the air ratio of an air-fuel premixture is subjected to fluctuations by installing a surface combustion mat which is provided with a special combustion area which specifies a specific value for the air ratio to the tip of a wind box. CONSTITUTION: A surface combustion mat 3 is installed to the tip of a wind box 1 where there is installed a special combustion area 2 which specifies an air ratio as 1. To produce the special combustion area 2, a special gas pipeline 4 is installed directly to the upstream side of the surface combustion mat 3 to which a partition plate 5 is installed. When a gas-air of a premixture is introduced into the wind box 1, the premixture passes through the surface combustion mat 3 and forms flat flames 6 on the combustion surface on the downstream side in a combustion chamber 8. During the formation of flames, the special combustion area 2, which creates partially an air ratio of 1, is installed to the combustion surface.  Therefore, this construction makes it possible to hold stable flames under a favorable combustion state and prevent the generation of an accidental fire resultant from blowing of flames as a whole burner.

Title: Production of galvanized steel sheet excellent in spot resistance weldability
Inventor: YASUDA KOICHI
IPC: C23C22/24
Filed: 1989-12-07
Abstract: PURPOSE:To improve deterioration of service life of an electrode at a time of resistance spot welding of a galvanized steel sheet by bringing the surface of the galvanized steel sheet into contact with a potassium bichromate aq. soln. whose pH and concn. are specified. CONSTITUTION:In the case of bringing the surface of a galvanized steel sheet into contact with a potassium bichromate aq.soln., when the concn. thereof is regulated to the concn. less than 0.01wt.%, sufficient effect is not obtained. Further, even when this concn. exceeds 10wt.%, the effect larger than it is not obtained and potassium bichromate is wasted. Therefore, the concn. of the potassium bichromate aq. soln. is regulated to 0.01-10wt.%. Effect is obtained in a short time by regulating this aq. soln. to an acidic aq.soln. of <=4pH. When the pH is regulated to the value less than zero, dissolution of plating into the liquid is caused and also adhesive property, etc., are deteriorated by the kind of plating. Accordingly the pH of the potassium bichromate is limited to 0-4. As a result, deterioration of the service life of the electrode is remarkably improved at a time of continuous spot welding.
