Title: Method for renewing block copy for printed matter
IPC: G03F1/00
Filed: 1992-03-25
Abstract: PURPOSE:To realize inexpensive printing by performing 1st printing after displaying a mark and a character, etc., which are to be changed on a 1st block copy and performing 2nd printing after performing masking to a 2nd block copy. CONSTITUTION:The block copy is renewed by forming the changed part of the 2nd block copy on the 1st block copy which is renewed and painting out the part of the 2nd block copy, which is before change. The position of the changed part which is formed on the 1st block copy is a position corresponding to the part formed on the 2nd block copy, which is before change, and the part of the 2nd block copy, which is before change, is painted out by performing the masking using a coating material 10 such as paraffin. Namely, the block copy is made by forming the part which should be changed on the 1st block copy and performing the masking so that the part of the original block copy, which should be changed, may not printed without newly forming the 2nd block copy. Therefore, the block copy is very easily and inexpensively renewed without remaking all the block copies.

Title: Circuit and method for signal transmission
Inventor: MIKI YOSHIO
IPC: H03M5/06
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce the maximum value and the average of the number of bits which change at the sometime, in the transmission of a logical signal. SOLUTION: This device is equipped with a logical circuit 100, which converts a logical signal of n bits into m pairs (m is an integer equal to one or larger) of a group of logical signals, where only k bits (k is an integer equal to one or larger) change, a transmission line for transmitting the m pairs of logical signals, where only the k bits change, and a logical circuit 103 which converts the m pairs of logical signals, where only k bits change into a logical signal of the original n bits. Thus, for the maximum value of the number of changing bits has the product of k and m as an upper limit. Also, when the product of k and m is less than n/2, the average number of changing bits can be reduced also.

Title: Magnetoelectric conversion element
Inventor: KAJINO TAKASHI
IPC: H01L43/12
Filed: 1984-04-02
Abstract: PURPOSE:To make it possible to perform bonding at low temperature, in a magnetoelectric conversion element having a compound semiconductor film on an insulating substrate, by forming an intermediate layer having a different hardness between an electrode forming bonding layer and the semiconductor film. CONSTITUTION:A semiconductor film 14 is formed on an insulating substrate 11, and an electrode 15 is formed thereon. The electrode 15 is composed of a contact layer 16 which connects the semiconductor film 14, an intermediate layer 17 thereon and a bonding layer 18 on the layer 17. The intermediate layer 17 comprises a material, whose Young's modulus is larger than that of the bonding layer 18. Thus the wire bonding of a wire 21 to the bonding layer 18 can be performed at a low temperature by using ultrasonic waves having low energy. Therefore thermal stress is not concentrated in the interface between the insulating substrate and the semiconductor film due to the heat yielded at the bonding and the insulating substrate in not separated from the semiconductor film. These improvement are achieved.

A pressing member 5 is also arranged to press the charging electrode onto the supporting roller 3. When a DC voltage is impressed on the charging electrode 2, a circumferential speed ratio of the supporting roller to the electrifying electrode is set equal to 1 or below. By this method, the electrifying electrode 2 gets bulged toward the downstream side, increases in discharging area on the upstream side of the contact nip and the potential by electrification becomes uniform. On the other hand, the circumferential speed ratio is set equal to 1 or more in the case of impressing an AC/DC-superimposed voltages.
