Title: Method and apparatus for measuring concentration of oxidizable substance in liquid to be inspected
Inventor: KOJIMA HIROSHI
IPC: G01N27/416
Filed: 1985-07-05
Abstract: PURPOSE:To effectively remove contamination adhered to the surface of a measuring positive pole during measurement, by immersing the measuring positive pole, a measuring negative pole and an electrolytic polishing electrode in a liquid to be inspected and constituting a galvanic cell of the positive pole, the negative pole and the liquid to be inspected. CONSTITUTION:A measuring positive pole 2, a measuring negative pole 1 and an electrolytic polishing electrode 3 are immersed in a liquid 4 to be inspected. At this time, a galvanic cell is formed of the positive pole 2, the negative pole 1 and the liquid 4 to be inspected and the positive pole 2 and the negative pole 1 are connected to an ammeter 5 to measure a current value. Because this current value is proportional to the concn. of an oxidizable substance, said concn. can be calculated. After the measurement of concn. for a predetermined time, the position of a change-over switch SW is changed over from AB to AC. Whereupon, the positive pole 2 is connected to the electrolytic electrode 3 through a power source 6 and the electrolytic polishing on the surface of the positive pole 2 is performed to remove scale. After a predetermined time, if the position of the switch SW is changed over from AC to AB, electrolytic polishing is finished and measurement is again continued.

Title: Cement additive
Inventor: ISHIMOTO HIROHARU
IPC: C01B39/02
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain a cement additive capable of inhibiting the acid deterioration and neutralization of concrete or mortar and capable of establishing a method for effectively utilizing the incinerated ash of paper manufacture sludge by mixing the incinerated ash of the paper manufacture sludge with the aqueous solution of sodium hydroxide, heating the mixture, and subsequently compounding the synthesized compound as the cement additive. SOLUTION: This cement additive is obtained by mixing 1 kg of the incinerated ash of paper manufacture sludge with 4-5 liters of a 2-4 mol sodium hydroxide aqueous solution, subjecting the mixture to a hydrothermal synthetic reaction at a temperature of 100-140 deg.C, washing off the excessive sodium hydroxide with water, drying the synthesized compound, and subsequently pulverizing the dried product into particles which contain the particles having particle diameters of <=75 μm in an amount of >=90% and have a high cation exchange performance. Sand and a cement whose 5-20 wt.% is replaced by the above cement additive are mixed with water and subsequently kneaded to obtain the cement concrete or cement mortar strongly resistant to acids.  Thus, the incinerated ash of the paper making sludge is effectively utilized to contribute to the reduction of the industrial wastes and the promotion in the recycling of the industrial wastes.

Abstract: PURPOSE: To enable the flash device to be controlled even if a sensor adapter is connected by mistake by connecting the adapter to a photoelectric element when it is mounted to the flash device and providing electrodes for making contact to photometric signal transmission electrodes to said adapter.  
     CONSTITUTION: When a sensor adapter 7 is mounted to the mounting jig 15 of a flash device 13 and a flash adapter 11 to the accessory shoe 5 of the camera respectively, the switch depressing member 7m of the adapter 7 is pressed by the pin 15m of the mounting jig 15. Then, the traveling contact piece 7QA connecting to the collector of the photo transistor 7a of a signal changeover switch 7Q connects to the stationary contact 7QC connecting to the stationary contact 7PC which connects to a photometric signal transmission electrode 7n. On the other hand, the changeover switch 7P is not depressed and therefore the traveling contact piece 7P connecting to the photometric signal transmission electrode 11n of the adapter 11 connects to the stationary contact 7PB which connects to the stationary contact 7QB.

Title: Semiconductor memory cell
Inventor: TERADA KAZUO
IPC: H01L21/8244
Filed: 1983-08-11
Abstract: PURPOSE:To reduce the generation of a soft error induced by radioactive particles such as alpha particles extremely by using currents flowing through an MOSFET as ON currents for the MOSFET. CONSTITUTION:Currents flowing through an MOSFET101 are considerably large because they are used as ON currents for the MOSFET. Consequently, generated currents from alpha particles, etc. are brought to the ON currents or higher, potential at a node N1 elevates at considerably fast speed in order to rise up to 1V order, and its speed is at 0.1 nano sec order. As a result, potential at a node N3 does not drop and reach to potential (approximately 0V) or lower at a node N4 during that time. Accordingly, the nodes N1, N3 return to SV and nodes N2, N4 to 0V, and the state before the projection of alpha particles, etc. is kept. Since a time constant T3 as the product of the capacitance of the node N3 and a resistor 105 and a time constant T4 as the product of the capacitance of the node N4 and a resistor 106 are larger than a time constant Talpha until a recovery by ON currents for the MOSFET after potential at the node N1 or N2 is changed by generated currents from alpha particles, etc., the state of a memory cell is kept, and a soft error is prevented.

Abstract: PURPOSE:To restrict an occurrence of CO as much as possible, make a superior ignition and reduce an ignition sound by a method wherein a controller is provided with a sequence for determining a variable time so as to increase an amount of transportation of combustion air for a combustion fan at the time of ignition as compared with an amount of air at a normal time after ignition. CONSTITUTION:A control of a combustion fan 5 near an igniting time under an operation of a controller 10 is performed such that the combustion fan 5 is rotated at the number of revolutions N1 with an operating signal through a motor at the time of pre-perging. When an accumulated operating time from an operation starting time of the combustion fan 5 reaches a predetermined time (t1) slightly less than a normal pre-perging time, the number of revolutions of the combustion fan 5 is defined as N2. After a time (t2) elapses with the number of revolutions N2, a gas solenoid valve 2 is turned on, fuel gas is supplied from a gas burner 3 to a burner 4, and then the burner 4 is ignited with a gas ignition transformer 6. At this ignition time, a more large amount of combustion air than that of the normal combustion is fed into the burner 4, thereby an occurrence of CO can be reduced.

Title: Method and apparatus for measuring potential in two-dimensional coordinate reading apparatus
Inventor: FUJITA HIDEO
IPC: G06F3/045
Filed: 1987-06-13
Abstract: PURPOSE:To measure the potential of a contact point with high accuracy, by providing a switch for alternately applying constant voltage to a pair of surface resistors and changing over one terminal of each of the resistors between an earth state and a floating state. CONSTITUTION:Switches 5, 6 for selectively changing over one electrodes 53b, 63b of the surface resistors 52, 62 of X- and Y-sheets 50, 60 to the input terminal of an earth or voltage measuring circuit 4 are provided. When the potential between a pair of sheet contact points is measured, for example, in the case of the X-sheet 50, the switches 5, 6 are set to a-sides and the voltage of an X-sheet power source circuit 1 is set to V1 and the voltage of a Y-sheet power source circuit 2 is set to 0. At this time, since one terminal is earthed, the voltage proportional to one coordinates is generated at the contact point with the other surface resistor 62. Since no current flows to the surface resistor 62 at this time, no voltage drop occurs and contact potential can be measured with high accuracy by eliminating internal resistance.
