Abstract: PURPOSE:To increase tunnel current density and reduce leakage current in a functional transistor which uses differential negative resistance based on tunnel effect. CONSTITUTION:The valence electron band energy of a source is increased more than the conduction band energy of a drain by using GaSb for a third semiconductor 4 of a source layer and InAs for a first semiconductor of a drain layer while a double barrier layer which uses InAs as a wall is clamped between them.

IPC: G03G15/05
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To realize the high speed recording by generating static for scattering toner separated from a toner carrier toward a recording component and forming continuously the electric field not scattering new toner from the toner carrier in the case of not applying the voltage for forming an energy to a control electrode. SOLUTION: The scattering of toner is controlled by a control electrode 5 by providing the voltage to the toner on a toner carrier 6a, and the voltage for forming an image which can generate the scattering of the toner to an image electrode 51 is applied in compliance with image signals, and static is generated on a conductive toner 91 layer surface by the voltage. After the toner is separated from a toner layer and the scattering is started, however, the toner is scattered as it is continuously even in the case of lowering the voltage and the electric field is weakened. In that case, the image electrode 51 is provided with the voltage of 180V at the time of forming the image and the voltage of 120V at the time of not forming the image.  Therefore, it is not necessary to wait for the changeover of the image electrode until the toner is passed through a hole 54 of the control electrode 5 and the high speed can be realized.

Title: Picture processing circuit
Inventor: SATO SHIGERU
IPC: H04N7/00
Filed: 1991-03-27
Abstract: PURPOSE:To improve the resolution with one picture memory by writing input picture in the picture memory in the blanking period of output picture read from the picture memory with respect to a circuit which writes the input picture in the picture memory and reads out it by a vertical synchronizing signal frequency different from that of the input picture. CONSTITUTION:A write counter 12 is used to designate the address of a picture memory 11 and is controlled by an input picture synchronizing signal and counts picture element clocks of the input picture. A read counter 13 is controlled by an output picture synchronizing signal and counts picture element clocks of the output picture. A selector 14 selects counted outputs of counters 12 and 13 and normally selects the output of the counter 13. Only when a signal indicating the read blanking period is outputted from the counter 13, the selector 14 selects the output of the counter 12. Thus, it is unnecessary that the access time of the memory 11 is especially short, and the resolution is improved with one memory 11.

Serial multi-valued digital image signals are inputted from a binary processing part 123 to a memory 110. The processing part 108 converts the signals to four color image signals so as to select and synthesize the signals sent from a binary synthesizing part 109 and the processing part 108.  When a plurality of images are present in a same band, the images, which are not adjacent to each other, are grouped so as to scan every group with a recording head in order to produce the images by scanning twice at the maximum.

Filed: 1989-04-04
Abstract: PURPOSE:To obtain fin material for heat exchanger capable of being soldered surely without damaging the complex film at the periphery by forming a complex of alkylimidazole and copper on the surface of a substrate comprising copper or copper alloy, and specifying the film thickness. CONSTITUTION:A copper alloy material is soaked into a mixed solution of alkylimidazole, acid, water, and organic solvent, and the film thickness are controlled by adjusting the soaking time. The copper alloy plate is withdrawn from the solution, and held for 20 seconds - 15 minutes for example at 80-200 deg.C, as a result, the formation of the complex of alkylimidazole and copper is promoted, and becomes a stable film. Even if the complex film exists thereover, it is possible to perform soldering. However, it becomes difficult to perform soldering as the film thickness is thick beyond 2mum. For this reason, the film thickness is limited to be 0.1-2mum.
