Title: Beam splitter for infrared
Inventor: IWAMOTO HIROMI
IPC: G02B5/28
Filed: 1989-01-21
Abstract: PURPOSE:To obtain sufficient light resistance and optical stability by determining the number of layers of multilayered dielectric films of an even number formed on one side surface of a substrate in such a manner as to attain a prescribed reflectivity and forming the films into a specific layer structure and forming antireflection films specific to light of the same wavelength on the other surface. CONSTITUTION:Zinc selenide (ZnSe) is used as the optical substrate 1 transparent to IR light and the many layers of the even numbers including a thorium tetrafluoride (ThF4) layer 4, a ZnSe layer 5,..., from the substrate side are constituted on the one side surface, S1 surface, of the substrate 1. The number of the layers is so determined as to attain the desired reflectivity, in addition, the film structure in which the transmittance spectra thereof attain the extreme value to the P polarized light of 45 deg. incidence and 5.3mum wavelength. The antireflection films having the optical film thickness determined in accordance with the condition equation for preventing the two-layered reflection of Shuster for the light of the same wavelength, i.e., the antireflection optical films consisting of the two layers, a ThF4 layer 8 having 0.810 optical film thickness and a ZnSe layer 9 having 0.371 optical film thickness are formed on the other surface, S2 surface. The high light resistance is obtd. in this way and the stability of the reflectivity in spite of a fluctuation in the oscillation wavelength is enhanced.

Title: Mold bushing, main circuit conductor outlet of electric apparatus
Inventor: YOSHIDA TETSUO
IPC: H01B17/26
Filed: 1993-01-28
Abstract: PURPOSE:To increase the breakdown voltage of a main circuit conductor outlet by making stronger the normal electric field strength than the tangential electric field strength of at least the insulation layer creeping surface near the center conductor cast of insulator. CONSTITUTION:An insulation spacer 9 has a normal electric field strength stronger than the tangential one on at least the creeping surface of an insulation layer 14 near a center conductor 10. The tangential component of the electric field strength is larger on the creeping surface of the insulation layer 14 because the equipmential lines cross almost at right angles when the angle between the insulation layer 14 and the center conductor 10 is 90. Conversely, the normal component increases when the above angle is almost zero. At a certain point of this angle, the normal and tangential components cross each other. The two components are minimized at this point because the absolute value of the electric field strength is suppressed. Thus, the breakdown voltage can be increased by keeping the above angles at this point.

IPC: C07D277/40
Filed: 1981-01-30
Abstract: PURPOSE: When crude 2-aminothiazole is purified by distillation, boric acid, sodium bisulfite and/or a phosphorous ester are added to the distillation system to inhibit the decomposition of 2-aminothiazole, thus increasing its recovery yield.  
     CONSTITUTION: For example, crude 2-aminothiazole is obtained by reaction of a chlorination product of vinyl acetate with thiourea in an aqueous medium followed by neutralization of the reaction product with caustic soda or so and it is subjected to disillation in the presence of a compound selected from boric acid, sodium sulfite and phosphorus esters of (RO) 3 P for purification. Thus, the high-purification 2-aminothiazole is obtained as the column top fraction and used as a diazo component of monoazoe dyes. The total amount of the compounds added for purification is preferably 0.5W1wt% based on 2-aminothiazole and almost all of them remain in the bottom on distillation.

Abstract: PURPOSE: To decrease an error, and to attain synchronous data transfer across an area boundary by using two single stage synchronous FIFO first-in first-out and N-2 stage multistage asynchronous FIFO instead of an N word multistage FIFO memory device. CONSTITUTION: Data and a writing signal are added to a first FIFO first-in first-out 12. When the writing signal is asserted, FIFO 12, 14, and 16 capture the data of DATAIN in the next rising edge of a clock signal. For example, the FIFO 12 connects an nEMPTY signal with the writing terminal of the following FIFO 14. For example, the FIFO 14 connects an nFULL signal with the reading terminal of the preceding FIFO 12, and connects the DATAOUT of its own (the FIFO 14) with the DATAIN of the following FIFO 16. Thus, serial connection can be attained. At a reception side, a reading signal is asserted, and data are read from the data output so that the data can be read from the second single stage FIFO 16. The data are written by one clock pulse.
