Title: Method for reducing ammonia gas generated from concrete structure and method for predicting amount of ammonia gas generated from concrete
Inventor: ONO SADATOSHI
IPC: E04B1/62
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To suitably determine selection of cement and aggregate for use in concrete, and the kind and amount of an ammonia gas reducing admixture to be mixed in the concrete while considering all conditions of the performance required for a structure, and of the workability and costs when the structure is constructed. SOLUTION: An ammonia gas concentration level which is not affected by ammonia gas generated from a concrete structure is set beforehand (S1), and designing conditions of the building structure and environmental conditions during the construction period are set beforehand. Thus, the tolerance of the amount of ammonia gas generated from the concrete is predicted and set based on the serviceability and designing conditions of the structure (S2).  When the amount of ammonia gas generated from the concrete is regulated with respect to the tolerance, regulation is made on at least one of the following elements consisting of the kind of the cement, the kind of the aggregate, selection of the ratio between water and a binder, the kind of an ammonia gas reducing admixture for the concrete, the amount of the ammonia gas reducing admixture to be added, and coating or affixture of an ammonia gas adsorbent or an ammonia gas decomposing material onto the concrete surface.

Title: Wavelength converting optical element
Inventor: HATAGOSHI GENICHI
IPC: G02F1/35
Filed: 1990-03-02
Abstract: PURPOSE:To provide the wavelength converting optical element having large conversion efficiency by locally changing the nonlinear optical constant of the part consisting of a nonlinear optical material in optical second higher harmonic wave generation of a Cerenkov radiation system. CONSTITUTION:The second higher harmonic waves are radiated as Cerenkov radiation waves into a substrate 10 by a nonlinear optical effect and the second higher harmonic wave 15 is outputted from the substrate 10 when a basic wave 13 is made incident on a waveguide part 11. Phase matching is taken automatically in the progressing direction of the basic wave but the phase in the layer direction is not matched in the optical second higher harmonic wave generation, i.e. SHG of the Cerenkov radiation system. The contribution to the conversion efficiency in the layer direction is inverted in code by places but the contribution to the conversion efficiency in the layer is negated by each other as a whole. The nonlinear optical constant is, therefore, changed locally. The wavelength converting optical element having the large conversion efficiency in the SHG of the Cerenkov radiation system is obtd. in this way.

Abstract: PURPOSE:To improve the post-etchback flatness of the surface of a conductive substance by supplying the surface of the conductive substance with an etching gas as velocity lower than the reaction rate of the etching gas to the conductive substance to each away the conductive substance projected from an opening section. CONSTITUTION:A tungsten film 13 is grown selectively by using WF6 and H2 to an SiO2 film 12 opened above a conductive layer 11 and the film 13 is etched back through chemical dry etching by an etching gas on heating of a substrate. 45Pa is employed as pressure, and feed-rate determination is acquired because the feed rate of a reaction gas is smaller than a reaction rate under the conditions. Consequently, an etching rate is increased in a projecting section having the large angle of estimation to the reaction gas, but, on the contrary, the etching rate is decreased in a recessed section having the small angle of estimation; therefore, the surface is easy to be flattened. Accordingly, flatness is improved as shown in Fig.b in the shape of a tungsten film 13a after etchback.

Inventor: SATO HIRONOBU
IPC: G03B3/00
Filed: 1987-03-06
Abstract: PURPOSE:To reduce defocusing due to the deficiency of a projection spot by using three photodetecting elements. CONSTITUTION:Signals from the three photodetecting elements A-C are amplified by an amplifier 12 and a comparative decision circuit 13 decides whether or not there are signals from the respective elements A-C. When the a subject moves from a focusing state to a close-distance side, a light beam is incident on only the element C or elements B and C and the circuit 13 outputs an NEAR signal to rotate an AF moor 15. When the subject moves in an infinite-distance direction, the light beam is incident on only the element A or elements A and C and the circuit 15 outputs an FAR signal to reverse the motor 15. If the received spot shape becomes a crescent shape 16, the crescent shape is in the area of the element 16, so there is no defocusing caused. This means that there is no defocusing when the subject has a contrast difference with the same subject distance.

IPC: G03G15/36
Filed: 1995-02-15
Abstract: PURPOSE: To decide bookbinding mode based on the image position to be recorded on a paper, and to automatically start recording operation. CONSTITUTION: A document is supplied on a platen glass by starting an automatic document feeder (S1), and distance A from an edge on a binding side to an image is measured (S2).

The bookbinding mode is selected based on the result. To put it concretely, a measured value A is compared with a specified value B, recording is performed in page order so as to perform finisher bookbinding in the case the measured value is larger than the specified value (S5), and the recording is performed in a state where the page order is rearranged so as to perform saddle stitcher bookbinding in the case the measured value is smaller than the specified value (S6).  Thus, the image omission is prevented so as to obtain high productivity.

Title: Focusing search method
Inventor: NAKAMURA HIDENORI
IPC: G11B7/085
Filed: 1989-03-02
Abstract: PURPOSE:To improve the accuracy of focusing search as the optimum point of read/write by evading an adverse effect due to crosstalk by remarking a kickback waveform when tracking servo is performed, and performing the focusing search by utilizing the waveform. CONSTITUTION:A D/A converter 23 converts a digital offset value to an analog quantity, and adds it on a focusing error signal. A peak detection circuit 24 detects and holds the positive side peak amplitude value of a tracking error signal. An A/D converter 25 converts the output of the peak detection circuit 24 to a digital value. A microprocessor 22 changes the digital offset value to be supplied to the D/A converter 23 in step shape, and stores an input value at that time from the A/D converter 25, and finds an offset value in which the maximum input value can be obtained. A just focal point is set by the offset value in which the maximum amplitude of the tracking error signal when kickback occurs is obtained by performing the tracking servo and performing the kickback shifting from one track to an adjacent track.
