Filed: 1995-04-20
Abstract: PURPOSE: To perform the closing operation of a spring-up type door from the position of an open state without a difficulty even when a drawer is locked by a safety locking mechanism. CONSTITUTION: The operation rod 13 of the safety locking mechanism for locking the remaining drawers to a storage position at the time of pulling out one drawer moves a lock lever 41 locking the spring-up door 3 to a drawer closing position to a door opening position at the time of moving into a direction for releasing the lock of the drawers. In the case the operation rod is operated and the drawer is locked to the storage position, when the spring-up door is in the open state, the lock lever is held at a door locking position by an operation control member 43. When the closing operation of the spring-up door in the open state is performed, the operation control member is pushed by the spring-up door and moved to a lever releasing position and the lock lever is released. Thus, the closed spring-up door is locked to the close position by the lock lever.

Title: Flat speaker
Inventor: ITO NORIHIDE
IPC: H04R9/06
Filed: 1986-05-28
Abstract: PURPOSE:To extend the frequency band of practical use by disposing a plate- shaped foamed material consisting of continuous foams in front of one surface or both surfaces of a diaphragm, thereby flattening the output sound pressure frequency characteristic curve. CONSTITUTION:The titled flat speaker is constituted of a ligh-weighted film- shaped diaphragm 1 on which a voice coil is printed, and a magnetic circuit consisting of a magnet 2 and a plate 3. The foamed material 4 is disposed in front of the diaphragm 1. This foamed material 4 is made of, for instance, a urethane foam made up of continuous foams. In such a flat speaker, the ligh-weighted diaphragm 1 oscillates in the magnetic circuit. Since this diaphragm 1 is light in weight, its radiation mass comes smaller in the higher band of frequency, and the characteristic curve is raised in the higher band of frequency as shown by the characteristic 5 in the figure. Also, since the foamed material 4 is disposed before the diaphragm 1 in the direction of sound wave radiation, the higher frequency components of the sound wave are absorbed by the material 4. As a result, the overall characteristic of the speaker comes to be a curve 7 which is flat over the wider range of frequency.

Title: Manufacture of embossed metal strip
Inventor: YOSHIDA AKISHIGE
IPC: B21B1/22
Filed: 1986-05-28
Abstract: PURPOSE:To prevent the generation of a camber at the rolling time of an embossing by arranging the dull roll of the roughness complied with the embossing pattern in opposing to the roll with pattern and adjusting the rolling reduction rate of both rolls. CONSTITUTION:The dull roll 2B rolling a metal strip 1 together with a patterned roll 2a is arranged in opposition to the patterned roll 2A subjected to an embossing. The roughness of the dull roll 2B is selected according to the embossing pattern and the rolling reduction rates of both rolls 2A, 2B is adjusted according to the embossing pattern. For example, in case of the embossing pattern being fine and complicated, the surface roughness of the dull roll 2B is made larger and the rolling reduction rate is made smaller. In case of the embossing pattern being simple, the reverse setting to the above is made. In this way the C camber of the embossing pattern giving rolling time can be prevented and the yield of the product is improved.

CONSTITUTION:An ingot of Nd-Fe-B alloy is subjected to a solid solution treatment, and then cooled slowly. While the treated ingot is cooled at a temperature lower than or equal to -40 deg.C applying dry ice, liquid nitrogen, etc., it is grained into pieces by a vibratory ball mill and the like to obtain fines having a mean grain diameter smaller than or equal to 200mum. Toughness of alloy is lost at a temperature lower than or equal to -40 deg.C, and so the grain distortion can be restricted to a minimum when the alloy is grained into pieces in this state. The alloy powder is subjected to a presure molding, in which plastic like epoxy resin is pregnated in a vacuum. Then it is subjected to a hardening treatment, and a compact is hardened to complete a plastic magnet having required mechanical and magnetic characteristics.
