Title: Method for determination of polycarboxylic acid
Inventor: MORISHITA MARI
IPC: G01N31/00
Filed: 1989-06-30
Abstract: PURPOSE:To obtain a result which is good in both reproducibility and sensitivity by adding bivalent or higher valency metal ions as a detecting reagent to a sample and calculating the concn. of polycarboxylic acid from the value of light absorption generated in a visible UV part by using an absorbance analysis method. CONSTITUTION:A prescribed amt. of the detecting reagent is added via a constant flow rate pump into the sample by a supply line of a means A for supplying the sample to be measured and a prescribed amt. of specimen liquid is prepd. by a metering instrument 1. While this liquid is mixed through a mixer 2, the liquid is withdrawn by a feed pump 3 into a flow call Q in the analysis apparatus of an absorbance analyzing means B. The light from a light source (W or D2) is imaged on an incident slit S1 by a spherical mirror M1 and is cast to a diffraction grating G by a spherical mirror M2 when the above-mentioned light source is lighted. The light dispersed therein is then passed through an exit slit S2 to enter the sample. The light transmitted through the sample enters a detector R and, therefore, the varying intensity thereof is converted to an electric signal by a detector. The electric signal is displayed as the absorbance. The concn. of the desired polycarboxylic acid is thus detected.

Title: Speaker device
Inventor: KITOU KOUJI
IPC: H04R3/04
Filed: 1980-12-05
Abstract: PURPOSE:To reduce distortion due to non-linearity of a speaker remardably, by transmitting a distorted signal of the speaker ro an output terminal of the speaker on another route from an original signal to make distortion correction of the speaker. CONSTITUTION:An original signal from an input terminal 1 is amplified with an amplifier 3A and applied to a speaker 4A. A voltage proportional to the acceleration of an oiscllation system of the speaker 4A is detected at an acceleration detector 5A, the detection signal is given to an equalizer 7A, where the level and phase of the detection signal are matched to those of the original signal respectively and outputted to a subtractor 2. The subtractor 2 subtracts the output of the equalizer 7A from the original signal to obtain a distortion signal, and this distortion signal is amplified with an amplifier 3B and applied to an equalizer 7B. The equalizer 7B adjusts the signal level and phase so that the distortion based on the non- linearity of the speaker 4A can be minimized and the signal is applied to a correction device 15 provided with the speaker 4A. Thus, an output sound pressure waveform without distortion and having the same waveform as the original signal can be obtained.

Title: Display board
Inventor: TACHIKAWA KENICHI
IPC: G01D13/12
Filed: 1989-06-30
Abstract: PURPOSE:To change the color of a display part without regard to turning on/off a light source by providing a display color layer and a ground color layer on the front surface of a substrate. CONSTITUTION:The display color layer 2 is formed by printing with heat sensitive ink which is discolored from a black-based color at a normal temperature to a red-based color at a high temperature. The ground color layer 3 is formed by printing with normal ink of black- based color. As the result, the color layer 2 and the color layer 3 becomes a single color of the black-based color at the normal temperature before starting operation. For example, by turning on a switch at the time of starting the operation, an electric heat wire 5 is energized. Then, when the substrate 1 becomes at a high temperature, the display color layer 2 is discolored to the red-based color and the display part A is displayed as the red-based color. As the result, a stand-by function is provided. Besides, as the result that the display color layer 2 is formed by printing with the heat sensitive ink which is discolored from a yellow-based color at the normal temperature to an orange-based color at the high temperature, the display part A is displayed in the yellow-based color at the normal temperature before the switch feeding the electric heat wire 5 is turned on. Besides, when the substrate 1 becomes at the high temperature by energizing the electric heat wire 5 at the time of starting the operation, the display part A becomes the orange-based color and the color sense in both of the display part A and a ground color part B becomes excellent without regard to turning off/on the light source.

Accordingly, in the case the wash basin 23 is newly provided when a toilet is repaired, it is not required to correct the raising of a plumbing pipe, and since wall or floor demolition work (carpenter work) is not required in the case the rising of the plumbing pipe is corrected, the construction labors can be reduced, and holding times can be also reduced by simultaneous execution of work such as waterworks and carpenter work. Accordingly, the whole construction cost can be curtailed.

Title: Bulging die with dispersion of residual stress
Inventor: TAKAHASHI TAKESHI
IPC: B21D22/20
Filed: 1983-09-19
Abstract: PURPOSE:To disperse and decrease adequately the residual stress in a bulging die by pressurizing the max. stress part of the tension generated in bulging at the stroke end of a press. CONSTITUTION:A work 8 is fixed by a die 3 and a plate 6 of a bulging die upon descending of a press ram 1. A spring 7 deflects while the work 8 is kept fixed upon further ascending of the ram 1 and conversely a punch 4 projects from the plate 6 and the work is bulged while the work is retained by a spring 5. The bulging part R where max. stress remains is strongly pressed at the stroke end of the press until the thickness decreases by about 0.05mm. in the tapered part 4 of the punch and the radius part of the die. The stress remaining in the radius part is thereby dispersed and decreased in circumferential and radial directions. The stress relief annealing and after-working are thus eliminated.
