Title: Preparation of acrylic acid ester or methacrylic acid ester
Inventor: SATOU TAKAHISA
IPC: C07C67/08
Filed: 1981-11-02
Abstract: PURPOSE:To prepare the titled compound in high yield, reducing the amount of by-products, and eliminating the recovering process of the unreacted alcohol, by adjusting the molar ratio of acrylic acid or methancrylic acid to the alcohol within a specific range, and directly esterifying under specific conditions. CONSTITUTION:The molar ratio of acrylic acid or methacrylic acid[hereinafter called as (meth)acrylic acid) to a 1-3C lower aliphatic alcohol is adjusted to 1 to 1.0-2.0, and the mixture is esterified in the presence of an acidic catalyst (e.g. H2SO4, sulfonic acid, etc.) at 60-100 deg.C to obtain an acrylic acid ester or methacrylic acid ester[hereinafter called as (meth)acrylic acid ester]. In the above process, the (meth)acrylic acid ester is fed from the outside of the system to the distillation column to obtain a distillate free from (meth)acrylic acid and composed of the objective compound, water produced by the esterification reaction, and the unreacted alcohol. The bottom liquid of the distillation column essentially free from the produced water is recycled to the esterification reaction. Since the amount of the unreacted alcohol is very small, it is not necessary to use the recovery process, and the whole process can be simplified.

Title: Hydrogen peroxide electrode
Inventor: MIYAI JINKICHI
IPC: G01N27/404
Filed: 1986-07-25
Abstract: PURPOSE:To decrease disturbing components and to exactly measure the concn. of hydrogen peroxide by forming a diaphragm consisting of a hydrophobic gas permeable membrane to the detecting end of a hydrogen peroxide electrode body. CONSTITUTION:The diaphragm 2 consisting of the hydrophobic gas permeable membrane is formed at the detecting end of the cylindrical hydrogen peroxide electrode body 1. The hydrogen peroxide in a liquid to be examined permeates the diaphragm 2 when the detecting end is immersed into the liquid to be examined contg. the hydrogen peroxide. Then the hydrogen peroxide contacts an anode 4 and a cathode 5, and electric current flows between the two electrodes. The hydrogen peroxide is detectable if a immobilized enzyme film is mounted to the diaphragm 2 in the case of using the electrode as an underlying electrode for an enzyme electrode. The outflow of an internal liquid 3 to the outside of the electrode and the inflow of the liquid to be examined into the electrode are prevented by using the hydrophobic gas permeable membrane as the diaphragm 2 and a geled electrolyte as the liquid 3 in such a case. The concns. of the hydrogen peroxide in various liquids to be examined are, therefore, exactly measured without being affected by the disturbing components.

Title: Nox treating device
Inventor: IKUTA KAZUNARI
IPC: B01D53/56
Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To maintain the activity of a reducing agent by utilizing a vortex motion and to obtain a practical NOx treating device by using mixed particles of Al, Mg, etc., as the reducing agent, housing the reducing agent in a cylindrical container, introducing exhaust gas along the inside wall of the cylinder and generating a vortex flow. SOLUTION: The particles, of Al, Mg, Zn having 0.01mm-about 1cm particle diameter are mixed and used as the reducing agent. When the reducing agent is housed in the cylindrical container 2 and an exhaust pipe of an engine, etc., is attached to the outside of the container 2, the exhaust gas 5-a flows from an introduction pipe 5a into a container bottom 2-a and then along the inside wall surface of the container and forms 12 vortex in the container 2. The particles in the vortical stream are always pressed to the cylindrical inside wall 2 with a strong centrifugal force and an oxidized coating film on the particle surface is destroyed and also an activated particle surface is generated by mutual collisions. Thus, device impedance against a gas flow rate can be lowered by making a packing ratio of the reducing agent small.

Title: Analog-digital converter
Inventor: YAMANISHI KAZUHIRO
IPC: H03M1/50
Filed: 1982-10-05
Abstract: PURPOSE:To ensure an A/D conversion with high accuracy without using any parts of high precision by measuring the charging time of an integration circuit by a counter after having a switch between a reference resistance and a resistance element to be measured and then obtaining the count value ratio. CONSTITUTION:First, a changeover switch 8 is connected to the side of a reference resistance Rr, and the control output is set at H. Thus a counter 1 starts its counting, and a switch element 3 is turned off. Then the output of the element 3 drops by an integration circuit consisting of a capacitor C and the resistance Rr. When this voltage becomes less than the voltage divided by resistances R1 and R2, the output of a comparator 4 is set at L. Then the counter 1 stops its counting, and the count value n1 corresponding to the time counted from the start of charging is obtained at a count output 1a. This value n1 is fetched into a latch circuit 6. Then the switch 8 is connected to a resistance Rx to be measured to obtain the similar count value n2. As a result, a count value ratio n2/n1 is obtained at an output 7a of a divider 7. This ratio n2/n1 is converted into the digital value in the form of Rx/Rr. Thus no effect excepting the ratio Rx/Rr is generated.

Filed: 1985-08-12
Abstract: PURPOSE:To reduce the dew-laden amount and to prevent fine appearance of the air conditioner from being impaired by mounting a water-absorbing plate on the inner surface of a dew receiver and providing the forward end portion thereof up to the inner surface of a guide member so as to block a guide hole. CONSTITUTION:Since a water-absorbing plate 19 is provided up to the inner surface of a guide member 14 so as to block a guide hole 13, an air flow from the back surface of the lower part of a guide unit to the guide hole 13 is substantially eliminated. Dew 20 laden on the front surfaces of a drain hose 8 and a pipeline 9 and dew 21 laden on the front surfaces of a lower wall 10 and a guide member 14 are minute in amounts to such a degree as not to drop. Since the water-absorbing plate 19 is mounted on the inner surface of a dew-receiving part 11, even when dew 23 deposited on the back surface of a base 4 and dew 22 deposited on the inner surface of a lower surface wall 10 fall dropwise, the water absorbing plate 19 sucks them up and diffuses them to promote the evaporation of the same. Further, the water-absorbing plate 19 is colored in black. At the time of installing the inside of the indoor unit is not visible from the guide hole 13 so that the air conditioner is fine in appearance.
