Title: Sound absorbing body
Inventor: CHOMEI HAJIME
IPC: E04B1/99
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To enhance sound absorption performance and to reduce a cost and weight by constituting a sound absorbing body of a fiber molding subjected to embossing on at least one surface. SOLUTION: At least one surface of the fiber molding is subjected to profiling as embossing. The profiling refers to the formation of corrugated ruggedness on the surface of the fiber molding. The waveheight of such corrugations is not particularly limited and is preferably specified within a range of 5 to 95% in the waveheight 2a with respect to a fiber molding thickness t. The more specific examples of embossing includes hot compression molding, profiling, etc. The sound absorbing body consists of the fiber molding according to such constitution and, therefore, the sound absorption performance is good. Since the fiber molding may be molded to a free shape, its weight and cost may be reduced by subjecting its surface to embossing.

Title: Weight deciding method
Inventor: KITAHASHI TADAHIRO
IPC: G01F17/00
Filed: 1984-09-19
Abstract: PURPOSE:To decide the weight of an object of measurement by projecting a slit pattern on the object of measurement and calculating the height of the object of each slit position from the degree of curvature of the slit on the object. CONSTITUTION:A slit projector C is provided slantingly above the object B of measurement mounted on a conveyor A and the slit pattern projected on the object is picked up by a television camera D installed above the ojbect, so that the slit appears to shift in position by d1-d4. This shift is checked to obtain the height of the body and the volume is found from the height and multiplied by the specific gravity to decide n the weight. Namely, its image is inputted to an A/D converter F and converted into an image of, for example, 256X256 eight-bit picture elements, which are stored in an image memory G. The memory G is connected to a CPUM through a bus line N together with hardware such as a floppy disk H, main memory I, printer J, CRTK, and keyboard L. The CPUM performs necessary processing to decide the weight of the object of measurement.

Title: Optical waveform equalizing and reproducing method
Inventor: NAGASHIMA MICHIYOSHI
IPC: G11B7/005
Filed: 1985-09-04
Abstract: PURPOSE:To reproduce a signal whose waveform has been equalized optically by dividing a photodetector into two, providing a dead zone between its two divided parts, and irradiating a low frequency component to this dead zone. CONSTITUTION:A photodetector 11 is divided into two, and photodetects a reflected light from an information recording surface 5 of an optical disk 4. Between two divided parts 11a and 11b of the detector 11, a dead zone 13 is provided. To this dead zone 13, light of a long and slender area which passes through the center of an objective lens 3, and also runs along the direction (the radial direction of the disk 4) vertical to a signal track is irradiated so that the divided part 11a and 11b do not execute photodetection. Accordingly, when photodetection is executed by this photodetector 11, an amplitude of a low frequency component can be made small, and a waveform can be equalized optically by reducing a reproducing signal amplitude of a low frequency, in a state that a reproducing signal amplitude of a high frequency remains maintained. According to this method, a waveform equalizing circuit is not required, or a simple one will suffice.

Title: Hot water supply apparatus having water heater and heat reserving function
Inventor: IDA TOMOYUKI
IPC: F24H1/10
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent unuseful heating by setting so that heat reserving combustion is not permitted even if detected temperature of hot water in a heat exchanger is not higher than a predetermined temperature until a heat reserving combustion waiting time set in advance elapses after a combustion for heat reserving. SOLUTION: During heat reserving combustion waiting time after a heat reserving combustion, a heat reserving combustion is not permitted even if temperature of hot water in a heat exchanger 18 is not higher than a temperature for starting heat reserving combustion. Even if heat reserving combustion waiting time elapses after the heat reserving combustion, heat reserving combustion is not performed by judging hot water temperature to be in a delayed rising process while hot water temperature is in an increasing trend, even if the temperature detected in the heat exchanger 18 is not higher than the temperature for starting heat reserving combustion, and when increasing gradient of hot water temperature becomes not greater than a set value, heat reserving combustion is permitted. By this method, unuseful heating is prevented.

Abstract: PURPOSE:To reduce a noise index and to obtain a noise-reduced low noise amplifier by using a coaxial waveguide converter setting up characteristic impedance on the coaxial side to the same value or less as the real number part of the impedance minimizing the noise index of a semiconductor element. CONSTITUTION:An impedance matching line 9 is an inductance or transmission line connected to the semiconductor element 4 in series and converts the impedance up to a real axis on a Smith chart. At that time, the impedance obtained by observing from a contact 11 between the coaxial waveguide converter 8 and the matching line 9 to the line 9 side is equal to the real number part R of the impedance minimizing the noise index of the semiconductor element 4 or a less value Z3. The setting of the impedance on the coaxial side of the converter 8 to Z3 matches the impedance between the line 9 and the waveguide. Thus, a 1/4 wavelength transformer which is necessary for the ordinary constitution can be omitted.

Abstract: PURPOSE:To detect the positions of two bodies, which are separated by a minute distance, by securing sufficient resolution for highly accurate alignment in accordance with the expression of a Rayleigh limit for the resolution and a focal depth. CONSTITUTION:The positions of two bodies, which are separated by a minute distance, are to be detected. For this purpose, images are formed accompanied by chromatic aberration on axis, which is equal to the minute distance with respect to light having a first wavelength (435.85mm) and light having a different second wavelength (546.07mm) by using a lens system. Said lens system is prepared. The first body, the second body and objective lenses III are relatively arranged so that the image forming plane of the first body with the light having the first wavelength and the image forming plane of the second body with the light having the second wavelength are located at the same plane. Meanwhile, the bleeding in the chromatic aberration at the image forming plane based on the image of the second body with the light having the first wavelength is removed. The bleeding in the chromatic aberration at the image forming plane based on the image of the first body with the light having the second wavelength is also removed. For this purpose, first and second filters are provided for the respective wavelengths. The images after passing through the filters are processed, and the position relationship between the two bodies is obtained.
