Title: Screen integrator
Inventor: KINOSHITA NOBORU
IPC: H04N5/21
Filed: 1982-07-20
Abstract: PURPOSE:To realize the function superimposing a screen, by compensating an address data of a memory in response to the amount of optical axis movement between a camera attitude angle and a frame for compensating the amount of optical axis movement. CONSTITUTION:An output of a delay circuit 4 is the camera attitude angle signal of a preceding frame and a subtractor 5 subtracts the camera attitude angle data of the preceding frame from that of the present frame, and the result is outputted as the optical axis moving amount between frames. The address data is outputted from a counter 2. When a clock is at H level, the address data correcting the amount of optical axis movement is outputted from an adder 7, and when the clock is at L level, the address data without compensating the amount of optical axis is outputted. The data of a memory 1 corresponding to them are averaged with weighting and stored in the address not compensating the amount of optical axis movement of the memory 1.

Title: Reception frequency converter
Inventor: YAMAMOTO OSAMU
IPC: H04B17/00
Filed: 1983-07-12
Abstract: PURPOSE:To measure the characteristics of only a high frequency amplifier by applying a DC bias from outside to a balanced mixer having a high frequency preamplifier. CONSTITUTION:A high frequency signal is supplied to a high frequency amplifier AMP via an input terminal T1 to be amplified and applied to a balanced mixer MIX. The signal applied to the MIX is mixed with the local oscillation signal supplied via an input terminal T2. Than an intermediate frequency signal is delivered. The DC voltage is applied to a terminal T4 to control properly the voltage of the T4. Thus the high frequency input side and the local oscillation input side of the MIX are made conductive. Therefore the characteristics of only the AMP can be separately measured.

Abstract: PURPOSE:To improve temperature measurement precision at a distant from a predetermined point. CONSTITUTION:A light pulse emitted from a high output pulse light source 1 falls into a measuring fiber 3. A spectral device 2 separates and outputs stakes light and anti-stokes light caused by Raman scattering out of back scattering light generated in the fiber 3.

Title: Combustion gas analysis device
Inventor: AKIYAMA KENICHI
IPC: G01N30/46
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To sensitively analyze a specific constituent such as benzene in exhaust gas. SOLUTION: A sample gas is measured by a metering pipe 15 and then is concentrated by a concentration part 13. A switching valve V4 is changed at a specific timing for sending the sample gas containing a constituent with C6 or less and that containing the constituent with C7 or more to switching valves V5 and V6, respectively. The switching valve V5 selects a range containing C4-C6 for sending to a focusing part 23. On the other hand, the valve V6 selects the range containing C7-C8 for sending to a focusing part 25, thus allowing only a target specific constituent to be subjected to chromatography analysis and obtaining a high-top peak being clearly separated without being disturbed by other substances. Also, the sample gas is concentrated immediately after metering, thus introducing a large amount of sample gas and hence further increasing sensitivity.

Title: Reactor core
Inventor: MIWA JUNICHI
IPC: G21C5/00
Filed: 1994-06-09
Abstract: PURPOSE:To suppress fluctuation in the lowering of output upon increase of void rate by providing a moderator region, having neutron slowing-down capacity lower than that of a moderator, for one or more fuel assembly loaded in the first cycle. CONSTITUTION:A fuel assembly 6 comprises a channel box 1 having sides of about 14cm, fuel rods 2 having diameter of 1-2cm, and a tube 3 having diameter of 3-4cm encapsulating heavy water 5 having neutron slowing-down capacity lower than that of light water 4 being fed between the fuel rods 2 for the purpose of cooling and moderation. Since the neutron slowing-down capacity of heavy water 5 is lower than that of light water, average energy of neutrons in the fuel assembly 6 is increased and thereby the negative absolute value of void reactivity coefficient increases. Consequently, even during the first cycle having higher ratio of delayed neutrons as compared with other cycles, variation of output can be equalized to that of other cycle upon application to a negative reactivity core 7. This structure suppresses fluctuation in the lowering of output upon increase of the void rate throughout the service life of the plant.

Title: Treatment of planographic printing plate
Inventor: URASAKI ATSUSHI
IPC: B41N3/08
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To improve stable ink accepting property without causing any change with lapse of time after making a printing plate by subjecting a planographic printing plate after development to a treatment which can reduce the surface charges generated in a silver image part. SOLUTION: In a planographic printing plate which uses a silver image as a ink-accepting part, an ion complex dissolved during development is reduced into a metal silver in an image area to form a silver image. Ions in the polarity opposite to that of the surface charges are withdrawn from the liquid by the influences of the surface charges so that an ion atmosphere phase different from the soln. is formed near the surface of the solid, namely, which forms a solid-liquid interface charge layer. The silver image surface consists of a mixture of reduced silver and silver ion complex not reduced. Therefore, the surface of the silver image has positive charges induced by the silver ion, and as a result, an interface charge layer with charges is formed on the surface of the silver image. Thus, by reducing the charges in the silver image, the ink deposition rate is significantly improved.
