Title: Improved particle beam imaging system with hollow beam lighting
Inventor: GOLLADAY STEVEN D
IPC: H01J37/153
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To improve the resolution with a given beam current by providing a lighting subsystem for increasing the average distance between charged particles within a particle beam in at least one lighting crossover image. SOLUTION: A lighting optical system 212 and an imaging optical system 214 are arranged about on a center axis 210, and spaced from a reticule (for example, mask) 220 set vertically to the center axis 210. A ring opening 240 is inserted vertically to the central axis of a crossover image 224b between a condenser lens 217 and a lighting lens 218. The ring opening 240 increases the average distance between electrons in the electron beam in the crossover image and the conjugate image succeeding thereto when the electron beam is changed from substantial, type to hollow type. If the ring opening 240 removes 50% beam current with a necessary current I, the throughput can be kept when the current is set to 2H, and the resolution can be increased. The orbit slippage aberration of the system can be reduced by 30% by numerical calculation.

Title: Production of polyisocyanurate
Inventor: KUSAKABE MASAHIRO
IPC: C08G18/00
Filed: 1985-07-16
Abstract: PURPOSE:To obtain inexpensively the titled polymer of a low residual monomer content and a low-MW, by reacting an aromatic diisocyanate by adding an organic carboxylic acid Na salt, a tert. amine compound and an organic carboxylic acid K salt as catalysts in the given order. CONSTITUTION:An aromatic isocyanate (A) (e.g., tolylene diisocyanate) is dissolved in a reaction solvent (e.g., butyl acetate). After adding 5-200ppm (in terms of Na), based on component A, of an organic carboxylic acid Na salt (a) as a catalyst (B), the solution is reacted at room temperature for 1-5hr. After adding 10-200ppm, based on component A, of a tert. amine (b), the reaction solution is reacted at 0-40 deg.C for 1-5hr and, after adding 5-200ppm (in terms of K), based on component A, of an organic carboxylic acid K salt (c), it is reacted at 0-40 deg.C. This reaction is stopped by adding a reaction stopper (e.g., phosphoric acid) when the NCO group content of the final reaction product is decreased to 20-40% of the NCO group content at the start of the reaction. In this way, a polyisocyanurate of a residual diisocyanate monomer content <=1wt%, based on the resin solid, is obtained.

Title: Inspecting method of ultrasonic diagnosing device
Inventor: ARITA KISHIO
IPC: G01N29/07
Filed: 1984-07-27
Abstract: PURPOSE:To inspect the deterioration state of a wood pole with high precision by attenuating an ultrasonic wave to a constant value when transmitting and re- ceiving the ultrasonic wave to and from the wood pole and measuring the propagation time of the ultrasonic wave. CONSTITUTION:The ultrasonic wave signal is transmitted from a transmission terminal 2a to a reception terminal 2b in a sectional direction of the wood pole 1. At this time, if there is a deteriorating part H, the ultrasonic wave signal passes through paths R1, R2, and R3, etc. Further, the ultrasonic wave signal is attenuated to the constant value and transmitted and its propagation time is measured and compared with the normal propagation time. At this time, a standard piece is used to calculate the frequency attenuation and propagation time of the ultrasonic wave previously, and a threshold value is so determined the propagation time is long. Then, the ultrasonic wave increases in propagation time above the threshold value regardless of the paths R1, R2, and R3 if there is the deteriorating part H. Therefore, the deterioration of the wood pole is inspected precisely because the ultrasonic wave signal is attenuated to the constant value.

IPC: F16C3/02
Filed: 1992-06-16
Abstract: PURPOSE:To accurately know the wear condition of spline teeth without releasing the spline. CONSTITUTION:Relating to wear examination of a spline, a spline drive shaft 1 having spline grooves is provided with displacement gages 3 and 4 and transmitters 5 and 6 which transmit the output signal of them on radio wave. The displacement gages 3 and 4 continuously measure how a specific point on the outer peripheral surface of a spline coupled drive wheel 2 having spline teeth displaces relative to a specific paint, used as reference, on the outer peripheral surface of the spline drive shaft in the direction of circumference or diameter by accelerating/decelerating the spline drive shaft 1. The output signal of the displacement gages 3 and 4 is transmitted by the transmitters 5 and 6 on radio wave, and is continuously received by a receiver 8 installed on the ground. The wear amount of a spline teeth is known from the difference between the maximum and minimum displacement values received. Therefore, a facility is not required to stop, so maintenance cost decreases.

Inventor: OOGATA SHIYUUZOU
IPC: H04N5/44
Filed: 1983-08-26
Abstract: PURPOSE:To obtain the best video image and sound by changing a transmission band characteristic when an electric field strength of a received TV radio wave is weak. CONSTITUTION:Transistors (TRs) Q2, Q3 constitute a comparator circuit comparing noise signal of a sound intermediate frequency detecting circuit and a reference voltage and the reference voltage is set optionally by a variable resistor VR1. When the electric field strength is weak and the noise is increased and then a base voltage of the TRQ2 is increased, the TRQ2 is conducted and also the TRs Q4, Q5 are conducted. Then an emitter current flows to the TRQ5, a part of the current is branched so as to conduct a switching diode D1 via a diode D2. Thus, a capacitor C7 is connected in parallel with a damper resistor R2 so as to change the transmission characteristic of the video intermediate frequency circuit thereby obtaining the best video image and sound.

Title: Semiconductor device and its manufacture
Inventor: KATO SUSUMU
IPC: H01L27/108
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To reduce the element separating area of a semiconductor device, by improving the element separation withstand voltage by making a trench capacitor to work as an element separating area in addition to a TEOS film. SOLUTION: The upper surface of a P-type silicon substrate is partially exposed by removing a TEOS film 45, a silicon nitride film and a silicon oxide film by anisotropic etching by using a resist patterned to a prescribed shape as a mask. In addition, trenches of approximately 7 μm in depth are formed below the TEOS film 45 not only in a cell capacitor section but also in a peripheral circuit forming section. In this case, not only the TEOS film 45 but also a trench capacitor 65 are made to work as element separating areas so that elements may be separated from each other by the film 45 and capacitor 65. Therefore, the element separation withstand voltages between P-type diffusion layers 52 and 46 and between N-type diffusion layers 53 and 47 are improved as compared with the conventional example by that of the trench capacitor 65.  In addition, the width of the TEOS film 45 can be reduced to approximately 0.3-0.5 μm.

Filed: 1983-08-30
Abstract: PURPOSE:To improve the resolving power of a black-and-white copy image by providing a diaphragm to the image forming lens of an optical system, and resetting a luminous flux splitting means and also reducing luminous flux passed through the lens by a stop mechanism in black-and-white copy mode. CONSTITUTION:The image forming lens 6 is a symmetrical type lens and is provided with the iris diaphragm 60 which varies in opening extent between the front and rear group lenses. This diaphragm is associated with the switching operation between a red-and-black copy mode and a black-and-white copy mode, and this diaphragm is fully open in the red-and-black copy mode and stopped to a preset F value in the black-and-white copy mode. A half-mirror 7 and a red filter 15 are put off in the black-and-white copy mode. Further, the iris diaphragm 60 is stopped down associatively with the switching to the black-and- white copy mode, so the depth of focus increases and the surface of a photosensitive body enters the range of the depth of field to improve the resolving power. Further, the spherical aberration of the lens is improved by stopping down the diaphragm, and a decrease in the resolving power in the black-and- white copy mode is prevented.

Filed: 1981-10-05
Abstract: PURPOSE:To perform reading and writing operation regardless of the direction of a card, etc., having a stuck magnetic tape, by recording data twice in the opposite directions of bits, and thus making the data, written for the 1st time and 2nd time, symmetric. CONSTITUTION:Data written on a magnetic card 1 are read by a magnetic head 2, amplified at a part 3, and converted by a demodulating circuit 4 into a binary number, which is transferred through lines 7 and stored in a memory 8. The stored data are analyzed by a control part 6. For data writing, data edited in the memory 8 are transferred through the lines 7 to a modulating circuit 5 to write the data on the card 1 through an amplifier 3 and a head 2. The sequence of the data in the memory 8 coincides with that of data written on the card 1, and editing is performed so that the sequence of bits of data written for the 1st time is made opposite to that written for the 2nd time, thereby writing the same data regardless of the running direction of the card 1. Further, those data are read and the control is simplified.
