Inventor: SATO MINORU
IPC: G03C1/06
Filed: 1995-01-13
Abstract: PURPOSE: To enhance stability in manufacture and, especially, to reduce deterioration of performance during storage, and to enhance resistance to stagnation of a coating fluid and aging stability under high temperature and high humidity by adding a specified step for specifying a silver potential at the time of preparing the emulsion and a specified radical scavenger. CONSTITUTION: The step of regulating the silver potential to the range of -200 to -50mV is included into the process of preparing the emulsion and the radical scavenger to be incorporated is represented by formula I or II in which each of R and R' is, independently, an alkyl or aryl group, and each of R1 and R2 is, independently, a hydroxyamino or hydroxy group or the like. The radical scavenger is designated as the compound capable of substantially decoloring carbionxyl (reducing light absorbance at 230nm, when a 0.05mmol/dm<3> ethanol solution of the carbinoxyl are mixed with 2.5mmol/dm<3> ethanol solution of the compond to be tested at <=25 deg.C by the stopped-flow method and change of the absorbance at 430nm with the lapse of time is measured.

Title: Image reader
Inventor: CHIBA HIROTAKA
IPC: H04N1/403
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To attain correct binarization even in the presence of large fluctuations of the read-out value of a white part generated due to sensor sensitivity variations or light source variations in a scanner or facsimile equipment or the like. SOLUTION: At the time of optically converting a character and an image into a reading electric signal, a white bottom value being the minimum value in the input data of a reference white part is detected by a white bottom value detecting means 7, and a black peak value being the maximum value in the input data of a reference black part is detected by a black peak value detecting means 8. Then, a threshold value S is generated based on the white bottom value WB and the black peak value with an expression S=α×WB(0<α<1), or S=α×(WB-BP)+BP(0<α<1) by a threshold calculating means 9. The generated threshold is equal to the white bottom value or less, to ensure binarization.

Title: Charge transfer device
Inventor: MAEKAWA SHIGETO
IPC: H01L29/762
Filed: 1990-01-29
Abstract: PURPOSE:To reduce charge transfer losses by forming a structure in which the oxide in the bottom part between transfer electrodes has a higher dielectric constant than the oxide immediately under the transfer electrodes. CONSTITUTION:Oxide 3 is provided under the polysilicon 4 for gate electrodes, and silicon nitride 6 is provided between the gate electrodes. The silicon nitride is thicker than the oxide film 3. The nitride has a higher (about two times) dielectric constant than the oxide. Because of the existence of the nitride film 6 on a channel 6 between gate electrodes, the capacitance Cg between the gate electrode and the channel is substantially equal to the capacitance CL immediately under the gate electrode although the former region has a greater effective oxide thickness than the latter region. Therefore, charge transfer losses can be negligibly small.

Title: Semiconductor device and manufacture thereof
Inventor: INOKAWA HIROSHI
IPC: H01L29/78
Filed: 1989-01-30
Abstract: PURPOSE:To provide a semiconductor device in which drain withstand voltage is not lowered with reduced parasitic capacitance, and a short channel and higher density are assured by forming an active region as a structure where the active region makes contact with a semiconductor substrate along a narrowed width plane including a direction connecting a source region and a drain region. CONSTITUTION:A source region 6, a channel region 3, and a drain region 7 of an insulating gate type field effect semiconductor device (IG-FET) make contact with an Si substrate 1 at portions under the respective regions. Accordingly, a hole generated in the vicinity of a drain by ion impaction immediately moves to the Si substrate 1. Hereby, in the case of an IG-FET on a SOI(Silicon On Insulator) where an active Si region is electrically floating, there is not caused the powering of the drain withstand voltage which is a conventional problem. Further, since the width of a portion with which each region makes contact with the Si substrate 1 is very narrow as being less than D, parasitic capacitance between partial substrates is reduced, allowing high speed operation.

Title: Magnetostrictive material
Inventor: UEDA TOSHITSUGU
IPC: G01D5/48
Filed: 1984-02-07
Abstract: PURPOSE:To increase the output of signals, to reduce loss of longitudinal elastic wave signals during propagation, and to augment mechanical strength by a method wherein the surface of a high-purity magnetostrictive material is coated with a chemical plate layer of the same material and then subjected to heat treatment. CONSTITUTION:On the surface of a high-purity magnetostrictive material A, a chemical plate layer is deposited by using a material B same as the material A except that it contains some P. The magnetostrictive material A may for example be electroformed Ni. The surface of the material A is thinly plated with an Ni layer B that is formed by a chemical process. Heat treatment follows that lasts for about 30min at about 650 deg.C. With the material being constituted as such, the pure Ni inside the material A is annealed to grow less hard while its electromechanical bondage coefficient grows higher. The surface layer B composed of Ni is hardened in the heat treatment because it contains some P, resulting in a good structural material excellent in its longitudinal wave propagating feature.

Title: Radiation picture information reader
Inventor: HANDA HIDEYUKI
IPC: G03B42/02
Filed: 1984-02-08
Abstract: PURPOSE:To simplify the structure of a detection surface and prevent a loss of a light beam for excitation by allowing the exciting light beam to strike an accelerated phosphorescent body panel at a specific angle to its normal direction, and setting the detection surface for generated phosphorescence at right angles to the normal direction of the panel. CONSTITUTION:When the exciting light beam is incident at the angle theta to the normal (n) to the accelerated phosphorescent body panel 13 to irradiate a point A on the panel surface, accelerated phosphorescence is generated near the point A and incident on the photodetection surface 53. The detection surface 53 is a filter surface and the reflected light of the exciting light beam in the incident light is cut off; and only the phosphorescence is transmitted through a filter 51 and converted by a photodetector 52 into an electric signal and then image processing and image reconstitution are carried out. In this case, the intersity of the accelerated phosphorescence has angle dependency and the component in the normal direction is largest. Thus, the phosphorescence is detected on the photodetection surface 53 most efficiently, the influence of the reflected light of the exciting light beam is reduced by the filter 53, and the incident light beam is not impeded, thereby improving the photoelectric efficiency.
