Patent JP-S5926742-A (JP)
Title: Electrophotographic developer
Inventor: KOBAYASHI HIROYUKI
IPC: G03G9/10
Filed: 1982-08-04
Abstract: PURPOSE:To obtain an electrophotographic developer remarkably improved in image quality and durability, by using a carrier having a specified average particle diameter with respect to that of a toner. CONSTITUTION:In a developer consisting of a toner and a carrier larger than this toner, the following inequality is satisfied: 2r1<r2<6r1 where r1 is average particle diameter of the toner, and r2 is that of the carrier. Furthermore preferably, the shorter diameter of the carrier to its longer diameter is controlled in 11/13-2/7 in ratio. Such a combination of the carrier and the toner selected in average diameter to the optimum range provides high abrasion resistance and prevents accumulation of fine toner tending to deteriorate image quality in a developing device. Further, the selection of the form of the carrier in said range tends to align the carrier particles in the direction of their longer diameter in a magnetic field, and raises electric conductivity as compared with spherical and nodulous resin-coated carriers and makes it difficult to cause edge effect and the like.

Abstract: PURPOSE:To realize reduction of the number of logic circuits, the cost reduction and increase of the package density each by making good use of the inductance of the print circuit connecting between the input and output amplifying TTL logic circuits and also adding the capacitor to form a resonance circuit. CONSTITUTION:Input waveform 1 is amplified at input amplifying TTL logic circuit 4, and intermediate transmission waveform 2 is supplied to m units of output amplifying TTL logic circuit 5 to obtain the output signal of waveform 3.

As a result, the resonance peak is formed at the fall and the rise of the negative pulse of waveform 2. And thus the L-level voltage of waveform 2 can transmit the negative pulse which is lower than the maximum L level decided by the TTL logic circuit, and accordingly the number of output circuit 5 can be increased up to 10 or more. As a result, the number of circuit 4 can be reduced to realize the cost reduction and increase of the package density.

Filed: 1986-06-12
Abstract: PURPOSE:To make it possible to detect erroneous use of a substrate readily, by providing a one-conductivity type measuring region, which is connected to a semiconductor substrate, in a reverse-conductivity type epitaxial layer, which is formed on a one-conductivity type semiconductor substrate. CONSTITUTION:On a P-type semiconductor substrate 1, an N-type epitaxial layer 2 is formed. The epitaxial layer 2 is isolated in an island shape by a P-type bonding and isolating region 3 for bonding and isolation. A P-type measuring region 4, which is connected to the P-type semiconductor substrate 1, is formed in the N-type epitaxial layer 2, so as not to contact with the P-type bonding and isolating region 3. When the resistance value between the P-type measuring regions or between the P-type measuring region 4 and the P-type bonding and isolating region 3 is measured, the erroneous use of the semiconductor substrate can be detected since the resistance value is proportional to the resistivity of the semiconductor substrate 1.

The holes 3 are intercommunicated with the adjacent holes 3 to form the many open holes 3X. The many hollow layers 4 are formed side by side in the concrete base material 2 so that the open holes 3X extend between the hollow layers 4 and the surface of the concrete material 1 and open respectively therein. Powder layers 5 consisting of powder 6 of vermiculite, etc., having the excellent sound absorption performance in the mediant and bass regions are formed in the hollow layers 4. When acoustic waves are made incident on the inside of the continuous holes 3X from the openings on the surfaces of the concrete material 1, the acoustic waves repeat reflection within the continuous holes 3X and the vibration energy of the acoustic waves are absorbed in the porous concrete material 1.
