Title: Cathode ray-tube for projection
Inventor: ASHIZAKI SHIGEYA
IPC: H01J29/86
Filed: 1981-09-08
Abstract: PURPOSE:To reduce largely a burden of designing a lesn on the part of a refractive lens by correcting an image surface curve aberration of five aberrations through a frontal wall of a glass bulb of a cathode-ray tube for projection. CONSTITUTION:A frontal wall 9 of a bulb composed of glass of a cathode-ray tube 8 is so formed as to be flat on the surface and convex on the inside respectively. Consequently an effective image surface 11 of a picture projected on a fluorescent screen 10 presents nearly a convex surface on the side of a refraction lens 2 and the optimum image surface comes near a plane thus making it possible to obtain a good picture quality all over a flat transmittance type projection screen 3. That is to say that the effective image screen 11 can be made concave on the side of the refractive lens so that generation of an image curve aberration can be checked even if a picture is projected on the flat projection screen.

Title: Modulator, demodulator and transmission system for ofdm transmission
Inventor: SHIRAKATA YUKIMUNE
IPC: H04J11/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To correct the phase error of respective sub carriers and to demodulate an OFDM symbol, even in the case that a frequency deviation and a time deviation are present between transmission and reception. SOLUTION: OFDM signals So', for which a known pilot carrier PC is inserted to a prescribed sub carrier SC, are turned to input, and the OFDM signals So' are separated into the respective sub carriers SC by being Fourier transformed by a fast Fourier transformer 5. In a data carrier phase error estimator 7, based on the pilot carrier PC of the separated sub carrier Sc', a phase correction amount Shc is obtained for the respective sub carriers SC. In a data carrier phase corrector 9, based on the phase correction amount Shc, the phase of separated sub carrier signals Sc' is corrected. By performing demodulation in a data demodulator 13 to the sub carrier signals Scr phase- corrected in such a manner, transmission data Sd' are reproduced.

Title: Boiler drum pressure control method
Inventor: FURUKAWA MASAAKI
IPC: F22B1/18
Filed: 1988-06-09
Abstract: PURPOSE:To control the pressure of a boiler drum without the generation of visible smoke and nitrogen oxide by selecting a control system whose output is smaller out of two control systems based on the application of a low selector and operating a dust collector. CONSTITUTION:Generally, there is only available a pressure control system which controls the quantity of dust based on the pressure of a boiler, directly manipulating a dust collector. However, the characteristic difference between the pressure of a boiler and the concentration of combustion waste gas oxygen will induce the generation of visible smoke in the shortage of oxygen. To solve this problem, attempts are made to cascade set a predetermined value of a forced air flow rate controller 18 based on an operation output MV01 and a reference value, compare it with a setting value V06 of a hearth oxygen concentration controller 21 through arithmetic operations and thereby obtain an operation output MV06. A low selector 28 selects a lower output out of the two operation outputs MV01 and MV06 and obtains an operation output Y04. This construction makes it possible to maintain the pressure of a boiler drum within a specified range and the concentration of waste gas oxygen within a proper range as well based on the control of the quantity of dust collection.

Title: Gas rice cooker
Inventor: TABATA MARI
IPC: A47J27/00
Filed: 1993-05-20
Abstract: PURPOSE:To prevent deterioration of food taste during the keeping of warmth by equipping this cooker with a means for controlling the temperature of rice during the keeping of warmth so that it may drop to a warmth-keeping stationary temperature within a specified time immediately after rice cooking. CONSTITUTION:The peripheral barrel of a rice cooker body 1 is provided with a heater H1 of 64W by on-off control and a heater H3 of 12W normally on are provided at, and the top cover 8 is provided with a heater H2 being Hi-Lo- controlled between 50% and 100% in output. The heaters H1 and H2 are controlled by the thermosensitive switch TS on a jar 2. Since the heater H2 at the cover is of capacity half as high as that of a conventional one, and besides it is controlled between 100% and 50%, it is heated with the capacity a quarter as high as that of a conventional one while it is higher than warmth-keeping stationary temperature, and by that amount the temperature drops quicker. Moreover, since an normally-on heater He of 12W is added to the 64W of H1 in respect of the body barrel 1, the lower section A is kept warmer than the upper space C. As a result, though a conventional one was requiring about 12 hours for its temperature to drop to its stationary level, this cooker requires only seven hours or less.
