Title: Monostable multivibrator having no malfunction due to make of power supply
Inventor: BAN ITSUKI
IPC: H03K17/22
Filed: 1979-07-26
Abstract: PURPOSE:To prevent the malfunction during the make of the power supply with a  simple constitution, by connecting the two diodes to each other at the cathode side and then isolating the charging current of the capacitor from the current flowing to the differentiating circuit. CONSTITUTION:Switch S is turned on at time t0; the negative trigger is supplied at time t1; the output pulse is terminated at time t2; the steady state is obtained at time t3; and switch S is turned off at time t4. Thus potential v'' at point x'' is reduced down to nearly OV since the flowing of the current is blocked by diode D-1 and although the residual charge of capacitor C-1 may reduce potential vx' at point x'. Then voltage V applied to the whole of monostable multivibrator circuit B is applied immediately to point x'' through capacitor C-2 and diode D-2 when switch S is turned on again at time t5. And voltage vx'' which is not reduced much becomes immediately higher than the forward voltage between the base and the emitter of transistor T-2 never to cut off T-2. In such way, the malfunction during the make of the power supply can be prevented.

Title: Flexible magnetic disk
Inventor: KIMURA SHIGEO
IPC: C09D5/23
Filed: 1984-05-14
Abstract: PURPOSE:To assure the surface roughness of a magnetic layer and to improve the runnability and durability by coating a magnetic layer having a specific thickness on a primer layer of which the surface roughness is increased in order to control positively the surface roughness. CONSTITUTION:The surface roughness of the primer layer is set within a 0.03- 0.3mu range of root-mean-square roughness. For example, the difference (h) between the heights of the adjacent crests and troughs is h1=H1-L1, h1i=Hi-Li and the root-mean-square surface roughness Rrms is expressed by the equation where the levels to make the crests are designated as H1, H2...Hi and the levels to make the troughs are designated as L1, L2...Li. The surface roughness of the magnetic layer is controlled by the surface roughness of the primer layer and therefore the durability and runnability are considerably improved without decreasing the magnetic characteristic of the magnetic layer.

Title: Conductive porous material and manufacture thereof
Inventor: SAKABE SETSU
IPC: C08L29/04
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To facilitate manufacture, increase a surface area and reduce degradation of conductivity despite of extension by dispersing and cooling a conductive material in a polyvinyl alcohol solution, and freezing water so as to obtain a fine three-dimensional mesh structure. SOLUTION: In a conductive porous material having a fine three-dimensional mesh structure, a diameter of a pore formed in the three-dimensional mesh structure is 0.5-5μm. In manufacturing the conductive porous material having such a fine three-dimensional mesh structure, a conductive filler is added and dispersed into a polyvinyl alcohol solution, and then, is cast into a mold, followed by quenching. With this treatment, water contained in the solution is frozen to produce segregation, thereby forming fine pores. Subsequently, the segregation is heated above a freezing point for thawing. The freezing/ thawing treatment is repeated, so that the pore is grown and gelation proceeds, thereby forming a mesh-like structure.  Consequently, almost all strain developed can be absorbed by deformation of the structure even if machining is carried out by uniaxial extension thus reducing degradation of conductivity.

Abstract: PURPOSE:To actuate at high speed the disk having large moment of inertia by providing the member easy to be subjected to elastic deformation in a rotary shaft direction and having a high friction coefft. in the space with a recording medium inside the groove of the abutting face of the recording medium of a turn table so that the upper face becomes higher than the abutting face. CONSTITUTION:A notch shaped groove 2a is formed in the circumferential direction with equal interval on the disk abutting face of a turn table 2 and an urethane rubber piece 8 is fitted into this groove 2a. The thickness of the urethane rubber piece 8 is formed so as to attain to about 30mum projecting amt. delta from the abutting face 2b of the turn table 2. In the case of the disk being fixed, the urethane rubber piece 8 is completely deformed up to the abutting face 2b, so the disk is supported by the abutting face 2b and yet by the fixture of the disk to the abutting face 2b, the friction coefft. becomes larger because of the respective contact of the abutting face 2b and disk, and urethane rubber piece 8 and disk. The high speed actuation of the disk having large moment of inertia is thus enabled.

IPC: B67B3/26
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a capping device more inexpensive than a conventional capping device in which a servo motor has been employed for each capping head. SOLUTION: When a capping head 3 passes through a screw zone C, the magnetic force of a permanent magnet 51 of the capping head 3 is acted on the magnetic force of a permanent magnet 55 in the screw C to rotate the capping head 3.
