Title: Magnetic recording medium
Inventor: KAWASE SHIGEKI
IPC: G11B5/733
Filed: 1988-04-11
Abstract: PURPOSE:To improve practicable durability in low-humidity environment by providing dynamic microprojections between static microprojections provided on the surface of a thin ferromagnetic metallic film contg. oxygen. CONSTITUTION:The dynamic microprojections 5 are provided between the static microprojections 3 provided on the surface of the thin ferromagnetic metallic film 2 contg. oxygen. The static microprojections 3 are formed by a method of dispersing microparticles of silica, alumina, titanium oxide, etc., into a suitable solvent and coating the dispersion on a nonmagnetic base 1. The dynamic microprojections are formed by a method of the similar coating on the surface of the thin ferromagnetic metallic film 2. The dynamic microprojections 5 come into direct contact with the surface of a magnetic head to decrease the true contact area at the time of high-speed sliding of a tape and the magnetic head, thereby suppressing the formation of the foreign matter coagulating on the magnetic head surface. The static microprojections 3 prevent the removal of the dynamic microprojections 5 from the tape surface by the high-speed traveling magnetic head. The still life particularly in low-temp. environment is thereby improved.

Abstract: PURPOSE:To make the correction processing of a characteristic curve proper to an original-film picture efficiency by printing in the film a standard-density chart when photographing, automatically calculating the curve which is proper to an original film picture after reading out the picture, and by executing an automatic correction toward the said curve. CONSTITUTION:On a plate, in addition to normal information of the data of photographing, the name and age of an object-person, the standard density chart made of arrays of plural small rectangular areas of different densities 15 is printed. The reflection density of each of the areas of the chart 15 is so adjusted that the logarithmical amount of exposures by the reflecting image of respective areas are arrayed on the X-ray film with a uniform difference between themselves when printing the chart 15. The transmitting-light-amount information on the X-ray film digitized by an X-ray-image digitizing device 30 is converted to an information of X-ray exposure amount based on the above mentioned information of the standard density chart 15.

Filed: 1993-04-15
Abstract: PURPOSE:To eliminate display defects of black spots or white spots by contact of a printing mask on the side of the printing mask in contact with the orientation surfaces of substrates by using the mask partially having projections. CONSTITUTION:The liquid crystal display element is produced by using two sheets of the substrates 1 facing each other, applying oriented films 3 on the substrates 1, further forming seals, etc., thereon and encapsulating a liquid crystal therein. A screen printing method is used for forming the seals, etc., and the printing mask 8 partially having the projections 10 from a mask base material 9 is used for the side of the printing mask 8 in contact with the orientation surface 3. The printing mask 8 is formed by a printing method using, for example, a polyvinyl chloride resin for the base material part 9 and using a vinyl acetate resin for the projecting parts 10. As a result, the generation of the black spots and white spots by the mask contact to impair the display quality of the liquid crystal display element is prevented. The similar effect is obtd. as well even if dents are provided partially on the same surface side of the printing mask 8.

Abstract: PURPOSE:To form an open face easily, extract the contents easily, use a bag in an upright position and dispose of the bag after folding, by making an uncomplete join of a sheet as a face for opening and its adjacent sheets on part of their border. CONSTITUTION:A sheet 4 as a face for opening and particular parts 11 and 12 on borders 5 and 6 between the sheet 4 and its adjacent faces 1 and 2, respectively, are not completely joined. Therefore, by holding peeled parts 4b and pulling them to a specific position as shown by dotted lines, the sheet 4 for an open face is peeled, so that the open face is created. At that time, because the particular parts 11 and 12 around the sheet 4 are uncompletely joined, the sheet can be easily peeled off the rim. After the se of contents 28, the bag can be folded into a smaller shape by folding a sheet 3 and the open-face sheet 4 inside along corresponding folding lines. Additionally, the bag can be kept stably upright by support parts 15 and 16.

Both of the friction members 4a, 4b are pressed by a clamping force to contact them. According to this method, the traveling wave of ultrasonic oscillation is generated in the vibrating body 2 and the friction member 4a of the side of the vibrating body when the high-frequency electric field is inputted into the piezoelectric body 1 whereby the friction member 4b of the side of the moving body is driven integrally with the moving body 3 by a friction force. When the electric power is not inputted, a brake torque, equivalent to the product of a pressing force, exerted between both friction members 4a, 4b, and a friction coefficient, is generated.

Filed: 1989-04-10
Abstract: PURPOSE:To extinguish arc in a short arc time by forming a surrounding passage around a movable arcing contact for blowing insulating gas in a buffer chamber to arc at the time of disconnection. CONSTITUTION:If a movable main contact 29 is moved right at the time of disconnection, insulating gas in a buffer chamber 35 is compressed by a piston 34, and it goes through a passage 37, a throughhole 38b, and a surrounding passage 40 formed around a movable arcing contact 39 to be blown to arc 41. In the meanwhile, when the movable main contact 29 gets apart from a fixed main contact 25, the arc 41 is produced between a fixed arcing contact 26 and the movable arcing contact 39. The arc 41 is produced between an end part of a recess part 26a of the fixed arcing contact 26 close to the fixed main contact 25 and an end part of the movable arcing contact 39. Insulating gas emitted from the surrounding passage 40 is thus applied to the root of the arc 41, thereby disconnection is achieved effectively before a distance between both contacts becomes large.

Title: Debugging device
Inventor: OTANI KAZUO
IPC: G06F11/28
Filed: 1990-04-06
Abstract: PURPOSE:To improve the efficiency of debugging work by executing the state display or stop/recovery of an application program according to an instruction from an external part without stopping a system. CONSTITUTION:The instruction is outputted from a console 6 to a debugger controller 31 and this debugger controller 31 dispatches a request corresponding to this instruction to a debugger interface 32. The debugger interface 32 checks the presence/absence of the request and when there in no request, the operation is returned to an application task 22 without doing anything. When there is the request, a processing to the request is executed and an executed result is outputted to a printer 8 or the console 6. Thus, since the state display or stop/start of the application task is executed by the debugger controller 31 added into a basic software, debugging can be efficiently executed.
