Title: Amplifying method of electrostatic latent images
Inventor: TATEISHI KAZUYOSHI
IPC: G03G13/00
Filed: 1978-06-14
Abstract: PURPOSE: To obtain plural sheets of copies from one time of electrostatic latent image formation by superposing a transparent insulation layer, material layer and charge detecting plate on a photosensitive plate, applying a DC electric field between the substrate and electrode and radiating light.  
     CONSTITUTION: A photosensitive plate 9 is constituted by a conductive substrate 1 and a photosensitive layer 2, and a charge detecting plate 10 is constituted by a transparent insulation layer 4, a material layer of transmittance changing with electric fields, e.g., field effect type liquid crystal 5 and a transparent electrode 6. Differences occur between the internal electric field of the liquid crystal parts 11 in proximity to the portions where there are surface charges 3 and the internal electric field in the liquid crystal parts 12 of the portions where there are no surface electric fields. When light 8 is radiated in this state from above the deecting plate 10, light is radiated only to the portions where there are the surface charges on the photosensitive plate 9. The carriers generated by this light are separated by the DC electric field applied by a DC power source 7 between the substrate 1 and electrode 6 and only the positive charges are induced in the photosensitive plate surface. Thereby, the latent images of weak intensity may be amplified and the sharp latent images may be obtained.

Title: Method for joining earthquake-proof member for column-beam frame
Inventor: KAMIMURA KENJI
IPC: E04H9/02
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To develop excellent earthquake-proof capacity by a method wherein a reinforcing plate made of high yield point steel is joined along the peripheries of bolt holes of a joining part positioned at the end of a hypersoft steel member constituting a brace. SOLUTION: A reinforcing plate 11 made of high yield point steel is joined along the peripheries of bolt holes of a joining part positioned at the end of a hypersoft steel member 5 constituting a brace 4 for giving vibration energy absorbing function. Then, a gusset 3 provided at the inside of a column-beam frame and the hypersoft steel member 5 are joined by friction jointing with high strength bolts 10. Therefore, the strength stronger than the strength of the hypersoft steel at the center of the brace 4 can be given without enlarging the width at the jointing part of the hypersoft steel member 5 and without requiring a large-scale increase of thickness for the plate for a short section. Accordingly, strong jointing can be made with influence of slippage caused by decrease of the plate thickness lessened, and excellent earthquake-proof capacity can be developed.

Title: Ac high voltage generator
Inventor: SUZUKI KOJI
IPC: B41J29/38
Filed: 1991-04-05
Abstract: PURPOSE:To provide an AC high voltage generator having wide control range for the DC component of load current in which power loss of bleeder resistor is reduced. CONSTITUTION:Upon increase of reference voltage VR at terminal P2, current of high voltage transistor Tr 3 constituting a series regulator increases and the output voltage of a converter transformer T2 constituting a DC variable output power supply drops. Upon decrease of the reference voltage VR, current of the high voltage transistor decreases and the output voltage of the converter transformer T2 increases. In such a manner, the series regulator and the DC variable output power supply cooperate to widen the control range of the DC component of load current. Since negative current is limited by means of the high voltage transistor Tr 3 when the DC component is close to zero and the output voltage of the converter transformer T2 drops when the DC component has a high negative value, power loss of bleeder resistor is reduced as compared with conventional one.

IPC: H03M7/30
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To decode plural runs and signed levels by reading the data only once. SOLUTION: An address number is generated from a prescribed number of variable length codes and a prescribed number of runs and signed levels corresponding to a prescribed number of variable length codes are stored in a storage address represented by the address number. Three sets of runs and signed levels (RN1, SL1, RN2, SL2, RN3, SL3) and UBs are stored in storage addresses denoted by a 13-bit address number A1. Thus, data including plural variable length codes are read and the data are used for address numbers to read to three sets of runs and signed levels in the prescribed storage addresses, then the plural runs and signed levels are decoded by one reading of data.

Abstract: PURPOSE: To form an electroluminescent layer with excellent crystal orientation and stoichiometry by forming an electroluminescent layer consisting of sulfide-based phosphors on a substrate by a vacuum evaporation method in ambient gas containing gaseous sulfur made to be plasma state. CONSTITUTION: Ambient gas containing hydrogen sulfide is led to a plasma generating container 4 through an introducing pipe 8A from an external container 7. The ambient gas containing sulfur is converted into plasma in the generating container 4 by a high frequency coil 9A. The generating container 4 has fine introducing holes 12 and can convert the ambient gas containing sulfur into plasma easily by heightening the pressure of the ambient gas in the generating container 4. The ambient gas converted into plasma is jetted like beams toward a substrate through the introducing holes 12. Regarding the shapes, the length, etc., of the introducing holes 12, the shapes and the number of the holes can be changed based on the spread and the distance of the beams.  An inert gas is made to flow simultaneously through an introducing pipe 8A to control the partial pressure control of the gas containing sulfur in the ambient gas containing sulfur. The directions of the introducing holes 12 are set toward the substrate and thus an electroluminescent layer is formed on the substrate.
