Title: Production of hollow body by electroforming
Inventor: TAJIRI KEISUKE
IPC: C25D1/02
Filed: 1990-06-08
Abstract: PURPOSE:To produce a hollow body whose hollow has a complex shape by electroforming by using a sublimable material which is solid at ordinary temp. as a filler forming a core. CONSTITUTION:P-dichlorobenzene melted by heating to 55 deg.C is poured into a spherical cavity in a metal mold 1 split into two through a Cu pipe 3, allowed to cool and solidified to form a spherical body 2. This body 2 is taken out of the mold 1, metallic Cu powder 4 is rubbed in the surface of the body 2 by hand and electric current is supplied with the pipe 3 as the cathode in a conventional Cu electroforming bath acidified with sulfuric acid to form an electrodeposited layer 5 of about 1mm thickness. The body 2 is then allowed to stand and the p-dichlorobenzene is sublimed and removed from the opening of the pipe 3 to obtain a hollow body.

Abstract: PURPOSE:To enable accurate feeding-out and feeding of a variety of media, by inputting and storing the size of media, sequentially feeding out one medium at a time from a stack of the media, and discriminating the propriety of the feedingout based on the stored size. CONSTITUTION:When the size of a printing paper 10 is inputted through a keyboard 11, the size is stored into a memory 14a. With a command for printing supplied, a feeding-controlling part 16 causes one of feeding-out parts 4a-4d to feed out a designated printing paper 10 from a corresponding one of hopper cassettes 3a-3d. Simultaneously, the memory 14a is searched for size data corresponding to the designated printing paper 10. The size data L thus read is converted into a time T1. The leading and trailing ends of the printing paper 10 fed out and fed are detected, and the time T2 between the detection of the leading end and the detection of the trailing end is counted by a timer 54. When a comparing and discriminating part 55 finds that T1= T2, a signal (a) is emitted, namely, the feeding-out/feeding of the printing paper 10 is judged as normal. When T1 (T2 or T1>T2, the paper 10 is fed to a rejecting part 3e.

Abstract: PURPOSE:To simplify the constitution of an external device by comparing the time differences with each other between the write and read set signals. CONSTITUTION:A comparison device 16 compares the time differences with each other between the signal synchronous with the write reset signal inputted to a write address generator 9 from a write reset terminal and the signal synchronous with the read set signal inputted a read address generator 10 from a read set terminal 8.
