Filed: 1981-09-11
Abstract: PURPOSE:To increase the effective surface area of a negative active material, and reduce the internal resistance of the said material by providing projections and indentations over the surface of the said material which touches a separator. CONSTITUTION:After a negative active material 5 made of a metallic simple substance such as lithium is pressed and fitted into a shallow negative terminal part 2 in a dry atmosphere, projections and indentations 10 are formed on the  surface of the material 5 by means of a press-work equipment 20. Next, a  separator 6 impregnated with electrolyte is connected over the surface of the  projections and indentations 10, and the negative terminal part 2 and a positive  can 1 packed with a positive active material 4 are assembled so as to obtain a  nonaqueous electrolyte battery. Here, the projections and indentations 10 break  through an immobile film formed over the surface of the negative active material 5 during its formation, so that an active metallic surface of the material 5  is exposed. As a result, the surface area of the material 5 is increased, the internal resistance of the material 5 is reduced, and the capacity of the discharge current of the battery is increased.

Title: Production of optical recording medium
Inventor: KANO NOBUHIKO
IPC: B29C39/42
Filed: 1987-06-08
Abstract: PURPOSE:To entirely eliminate intrusion of air bubbles into a 2P curing resin by carrying out an operation for packing a photopolymer between a stamper surface and transparent substrate in vacuum environment. CONSTITUTION:A replica for an optical recording medium is prepd. by packing the 2P liquid between the stamper 4 and the smooth substrate 1' in a vacuum, then curing the 2P liquid with a UV ray exposing device. The intrusion of the air bubbles into the 2P curing resin is entirely eliminated in such a manner, by which the burst error occurring in the intrusion of the air bubbles is eliminated. The 2P liquid is hardly subjected to the inhibition of polymn. by oxygen and the curing reaction thereof is exceedingly enhanced even by the projection energy of the same UV rays. The presence of the unreacted monomer which accelerates the oxidation of the optical recording medium is thus greatly decreased and a remarkable improvement in the weatherability of the optical recording medium is attained.

Title: Method and apparatus for removing peripheral surface layer from article roll package
Inventor: NOSAKA YOSHIKI
IPC: B65H19/10
Filed: 1989-06-05
Abstract: PURPOSE:To permit an easy and accurate removal of the peripheral surface of an article roll package without causing any damage to the roll inside the package and without the need of any manual operation by a method wherein a very thin surface layer of the packaging material is partially removed at a time until the roll is exposed and the occurrence of the roll exposure by peeling off the package surface is detected by a sensor. CONSTITUTION:A movable body 10 is fed along a guide rod 8 so as to partially remove a very thin surface layer of the packaging material R1 of an article roll package R at a time. A motor M2 is regularly rotated for only a predetermined time and an end mill 15 is fed for only a short distance in a predetermined axial direction. A sensor S for distinguishing between the physical property of a roll Sh and that of the packaging material R1 produces a signal upon the occurrence of the exposure of the peripheral surface of the roll Sh due to the complete removal of the packaging material R1 resulting from the axial feeding of the end mill 15 at a time. If the removal of the packaging material R1 is not accomplished, the signal is not produced from the sensor S and a stepping motor SM is rotated in such direction as to permit the end mill 15 to further remove the surface layer of the packaging material and, at the same time, the motor M2 is reversely rotated to feed the end mill 15 in the reverse axial direction so as to further peel off the same part.

Title: Method for forming pattern
Inventor: YASUTAKE NOBUYUKI
IPC: G03F7/20
Filed: 1986-06-20
Abstract: PURPOSE:To improve the pattern precision extending over the boundary portion by dividing the electron beam exposed dose of the subfield boundary portion among the pattern forming regions remote from the boundary and the joint correction regions, thereby obtaining the exposed dose required for forming the entire region. CONSTITUTION:When the main field MF of a wafer is divided into subfields SF1, SF2 and a pattern is formed over the boundary portion B, an electron beam is first applied to the pattern forming regions P1, P2 on both sides of the boundary B, and the electron beam is applied to joint correction regions P11, P12 with a dose (0.5) smaller than the exposed dose (1) of the regions P1, P2, thereby making the sum of the exposed doses of the regions P1, P2 and the correction regions P11, P12 equal to the exposed dose for forming the region MF. With this method, the precision of a pattern extending over both sides of the boundary portion can be improved, and various patterns can be formed with good precision through adjustment of the exposed dose while taking into consideration the proximity effect at the subfield boundary and the thermal effect due to time difference of the beam exposure.

Abstract: PURPOSE:To shorten the stagnation time of a communication frame after completing multiple address communication by deleting the communication frame when a value reduced with a decrement means shows zero, and transmitting the communication frame to a connected communication channel other than the communication channel with which the communication frame is received when it shows the value other than zero. CONSTITUTION:When the multiple address communication is performed, the number of all the nodes in a network is transmitted after being written on a relay node number area 10 in the communication frame with a node number write means 11. And the value of the relay node number area 10 is reduced by one at every passage of each node with the decrement means 12, however, the communication frame always passes all the nodes in the network until the value of the area 10 reaches zero, which enables the multiple address communication to be performed, and when the value shows zero, the communication frame is deleted. Therefore, no eternal stagnation of the communication frame in the network occurs. In such a manner the stagnation time of the communication frame after completing the multiple address communication can be shortened.

Abstract: PURPOSE:To produce a wide-area photoreceptor in an economical way without using an evaporating device, by using a photoreceptor containing a photoconductive layer provided as if it covers one side and an aperture of a conductive substrate having a microaperture. CONSTITUTION:A substrate 8 is buried into a photoconductive layer 9 or a part of the substrate is sunk into the layer 9. When the bias voltage is applied between the substrate 8 and an electrode 12 while the image-shaped light is irradiated to a photoreceptor, a plus (+) photocarrier produced within the layer 9 shifts toward an insulated sheet 11 at the bright side of an image. Thus a charge layer is formed at the interface between the sheet 11 and the layer 9. While no charge layer is formed at the dark side of the photoreceptor since the layer 9 does not conduct. The separation is possible even at the bright side, is the voltage applied from a power supply 15 before the sheet 11 is turned off from the photoreceptor.
