Title: Optical fiber base material producing apparatus
Inventor: EDAHIRO TAKAO
IPC: G02B6/00
Filed: 1978-09-20
Abstract: PURPOSE:To produce an optical fiber base material homogeneous in the longitudinal direction by detecting the wt. of glass fine particles adhered per unit time and by setting a unit for controlling the wt. so that it is held constant. CONSTITUTION:Glass fine particles are spouted from nozzle 2 and deposited on the tip of starting material 21 to form glass fine particles deposited body 3. In accordance with the growing speed of body 3, material 21 is pulled to convert body 3 into transparent glass base material 22 with electric furnace 19 and heater 20. At this time, the total wt. of material 21 and body 3 is detected with wt. detector 23 set on material 21. Wt. increase DELTAW follows the line in the diagram, yet it changes slightly when DELTAW is differentiated with respect to time change delta like DELTAW/deltaT in a circuit system. A factor for this change, e.g. the temp. of nozzle 2 is controlled with temp. controller 26 to minimize differential value DELTAW/deltaT2. Accordingly, by holding the wt. of glass fine particles adhered per unit time constant a homogeneous optical fiber base material is obtd.

Title: Latent image recording method and latent image recorder
Inventor: SUDO AKIO
IPC: G03B17/24
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To clearly and uniformly record a latent image on color and black- and-white photosensitive material with extremely simple constitution by using a pulsed-light emitting light source where peak wavelength and luminosity are respectively set to specified values as a light source and exposing and recording the latent image on the photosensitive material. SOLUTION: This latent image recorder 10 is provided with the light source 14, and the light source 14 has plural LEDs 16. Each LED 16 constitutes the puled-/light emitting light source where the peak wavelength is set to 400 nm to 700 nm and the luminosity is set to 250 mcd to 1200 mcd, and is fixed on one side surface of a guide plate. The LED 16 is driven and controlled so as to expose and record the latent image on film F. Therefore, sufficient light emitting luminance is obtained in the short wavelength region of 400 nm to 500 nm necessary to overprint the latent image on the black-and-white film. Besides, the constitution of the entire device is simplified in comparison with the device using the LEDs having the light emitting characteristic of R, G and B.

Title: Continuous casting method and pouring nozzle
Inventor: HAMAI KAZUO
IPC: B22D11/10
Filed: 1988-05-16
Abstract: PURPOSE:To improve the quality of slab surface by forming the part contacting with meniscus part in the pouring nozzle and neighborhood thereof as the electric conductive heat generating part and heating with electric conduction from neighborhood of the meniscus. CONSTITUTION:Single or plural number of the pouring nozzles 11 are formed to a flat-shape and also at least made of the electric conductive material of alumina-graphite (Al2O3: 75%, C: 15%) etc., at least at the meniscus part of the molten metal containing the neighborhood. Further, the part except the exothermic part is constituted of insulating material. Before starting casting, the electric current is conducted to the pouring nozzle 11 from an electric source 41 through bus bar 35 and electrode 39, to heat the nozzle 11. By raising the temp. of the nozzle 11, the temp. near the meniscus (m) becomes higher than the temp. at the other part. Under this condition, at the time of pouring molten metal M from the nozzle 11 while circulating belts 22 and short sides 27, the meniscus part (m) is held to sufficiently high temp. In this way, sticking of the molten metal on the slab surface is prevented and the surface quality is improved.

Title: Core of fast breeder
Inventor: HATTORI SADAO
IPC: G21C5/12
Filed: 1987-05-15
Abstract: PURPOSE:To dispense with a bracket and to make a nuclear reactor simple and compact, by using a ternary alloy metal composed of uranium-plutonium- zirconium as fuel and setting a breeding ratio to 1.0 or more. CONSTITUTION:As the constitution of a fuel element, a uranium-plutonium- zirconium ternary alloy (ternary alloy) is used in place of conventional oxide mixture fuel. Since this ternary alloy is as high as about 1.5 times in density as compared with that of the conventional oxide mixture fuel and contains no light nuclide, the neutron spectrum in a case constituting a core becomes high. Further, it is unnecessary to provide a bracket and a breeding ratio can be set to 1.0 or more over a sufficient long-term combustion period and the core sufficiently little in the reduction quantity of reactivity due to combustion can be constituted. Further, since the ternary alloy is good in the coexistence with sodium, sodium can be used as the thermal bonding material in the fuel element. By this method, the miniaturization and simplification of a nuclear reactor can be achieved.

Title: Oscilloscope synchronizing circuit
Inventor: SUZUKI SATORU
IPC: G01R13/32
Filed: 1985-05-30
Abstract: PURPOSE:To expand the adjusting range, by applying an AC signal to a phase correction circuit to generate tilt signals different in polarity from one another with a waveform converter, enabling the adjustment of the synchronous level almost proportional to the phase of an AC signal for main power source. CONSTITUTION:A resistance 15 and capacitor 16 composes an integrator having a time constant T1. The output waveform of an operational amplifier 14 is converted to that a2 when T1>>T0 with the cycle of the AC voltage for power source as T0 to generate a phase deviation of T1/2 radian in the output of the operational amplifier 14 with respect to the power source AC voltage a1. After the removal of DC component with a capacitor 17 and a resistance 18, the output waveform a3 is applied to a positive input of an operational amplifier 19. The operational amplifier 19 compares the voltage applied to the positive input with the ground potential, amplifies the results and outputs a square wave signal b1 to an integrator with the time constant T2 composed of a resistance 20 and a capacitor 21. When the time constant T2 is T2>T0, the waveform is converted into an angular wave signal b2 the same in the phase as the main power source AC voltage and the DC signal component of the angular wave is removed with a capacitor 22 and a resistance 23 to obtain an AC signal of the triangular wave at an output terminal 24.

Title: Logical computing element and controller using the same element
Inventor: ASADA NORIHIRO
IPC: H03K19/007
Filed: 1989-05-10
Abstract: PURPOSE:To reduce the size and price of the computing element and to improve its function by utilizing an AC electric signal or intermittent light as an input signal. CONSTITUTION:When energy is inputted to two input circuits la and 1b of an input part 1 at the same time, one output circuit 2a turns on and the other output circuit 2b turns off. Therefore, a posture or negative source voltage is outputted to the output terminal of an output part 2. Further, when the energy is inputted to neither of the two input circuits 1a and 1b of the input part 1, the input circuits 1a and 1b turn off, and consequently one output circuit 2a of the output part 2 turns off and the other output circuit 2b turns on. The negative or positive source voltage is therefore outputted to the output terminal of the output part 2 and when an ON-OFF alternating input is supplied to the two input circuits 1a and 1b at the same time, an alternating output synchronized with the input is obtained at the output terminal. Consequently, the size and price are reduced and the function is improved.
