Filed: 1989-05-15
Abstract: PURPOSE:To measure dust on a magnetic disk with high accuracy by arranging a suction member so as t position the suction port of the dust between the magnetic disks, and mounting an exhaust port at a cabinet. CONSTITUTION:The suction member 11 is arranged so as to position the suction port 11a of the dust between the magnetic disks 2, and also, a base terminal part 11c having the exhaust port 11b of the member 11 is mounted on the upper wall plane of the cabinet 1.

Filed: 1982-07-13
Abstract: PURPOSE:To mass-produce polarizers at low cost by forming a fine grating pattern on a substrate surface, dipping the substrate in an electroforming bath, and working a metallic layer separated from the substrate. CONSTITUTION:An oxidized film 12 is formed on a surface of the silicon substrate 11 to, for example, 1,000Angstrom  thickness and polished into a specular surface, then a gold film 13 is vacuum-deposited over the entire surface of 4,000Angstrom  thickness. Then, the gold film 13 is coated with a negative electron beam sensitive resist film (chloromethylated poly-alpha-methyl styrene) to about 3,000Angstrom  thickness, which is exposed to an electron beam; and the film is developed with acetone and rinsed with isopropanol to form a grating-shaped resist pattern. Consequently, polarizers which each use synthetic resin as a base and have the fine grating pattern are mass-produced at low cost.

Title: Transistor driving circuit
Inventor: MAEKAWA HITOSHI
IPC: H04N3/16
Filed: 1984-06-15
Abstract: PURPOSE:To shorten the drop period of a driven transistor (TR), to reduce the loss of the driven TR and to prevent the titled circuit from the generation of a thermal runaway phenomenon by increasing the magnetic flux density of a driving transformer and turning on the driven TR by its carrier accumulating effect for a prescribed period before turning on the driven TR on the basis of magnetic saturation. CONSTITUTION:When a TR14 is turned on by a TOFF pulse from a time t0, an output TR5 is biased in the reverse direction and turned off at a point t1 of time. If a TOFF pulse B is turned to ''0'' and a TON pulse C is turned to logically high at a time t2, said output TR5 forward biased from the reverse bias state by a driving TR14 for a TON period, so that an excessive carrier is accumulated between the base and emitter of said output TR5. Consequently, the output TR5 is turned on by said excessive carrier. Thus, the drop period of the output TR5 can be shortened.

Filed: 1987-05-19
Abstract: PURPOSE:To obtain the excellent hiding power desired as a background material and to improve display quantity by constituting the background material of a material contg. fibrous materials consisting of the alkali metal salt or alkaline earth metal salt of titanic acid. CONSTITUTION:The fibrous materials consisting of the alkali metal salt or alkaline earth metal salt of titanic acid to be used as the material for the background material 10 is of a white system having the hiding power equiv. to the hiding power of titanium oxide powder and the sizes of the fibers are 0.1-50mum diameter and about 10-500mum length. The fibers are smaller in both the true sp. gr. and bulk sp. gr. than the titanium oxide powder. The fibers, therefore, have good affinity to an electrolyte 11 and since an effect of the entanglement of the fibers with each other in the electrolyte can be expected, the dispersibility in the electrolyte 11 is exceedingly outstanding. A high degree of the hiding power desired as the background material 10 is thereby sufficiently exhibited if the background material 10 is used in the state of being dispersed in the electrolyte 11.
