Title: Call current supply circuit
Inventor: MUKAI KANJI
IPC: H04M19/02
Filed: 1980-04-04
Abstract: PURPOSE:To reduce a call current and protect a call current supply circuit from an excess current, by increasing a DC impedance of the call current supply circuit, in case when abnormal overvoltage is genersted in a telephone line. CONSTITUTION:The terminals 1, 2 are connected to one pair of telephone circuits, and the terminals 3, 4 are connected to the electric power source. For instance, in the event of ground-fault of the terminal 2, the voltage between the terminal 2 and 4 rises abnormally, by which the transistor 20 conducts. As a result, the voltage between the noninversion input terminal of the optional amplifier 18 and the terminal 4 becomes small enough comparing with the voltage between the noninversion input terminal of the operational amplifier 18 and the terminal 2, therefore, the DC impedance between the terminal 2 and 4 incereases, and a current flowing into the first transistor 12 and the resistor 14 can be reduced. The circuit between the terminal 1 and 3 is operated in the same way, ane the first transistor 11 and the resistor 13 are protected.

Title: Controller for input heat value to boiler
Inventor: HAYASHI KOUICHIROU
IPC: F22B35/00
Filed: 1978-04-18
Abstract: PURPOSE: To prevent the excessive rise in the temperature of steam and the rupture of a boiler tube, by controlling the heat value of input fuel depending on the flow rate of feed water to a boiler to keep the temperature of steam constant.  
     CONSTITUTION: When an input heat value controller is in a state of equilibrium, the flow rate of feed water is equal to a command and corresponds to the input heat value. Because the input heat value is the product of the quantity of input coal with the output signal 6 of a temperature controller 6, the flow rate of feed water corresponds to the product of the quantity of input coal with the output signal of the temperature controller. Therefore, the excess or shortage of the quantity of input coal due to the trouble in the input heat value controller 10 or the wrong operation by an operator can be immediately detected by a comparator 11 which compares the flow rate of feed water with the input heat value. When the calorific power of coal changes, the flow rate of feed water varies slowly. At that time, the temperature controller compensates the increment or decrement corresponding to the variation. Thus, the variation is not detected by the comparator 11.

Title: Method for determination of cobalt
Inventor: MAEKOYA CHIAKI
IPC: G01N31/22
Filed: 1981-03-26
Abstract: PURPOSE:To determine cobalt by making use of the dependency of the speeds at which specific peaks appear in absorption spectra when 1,2-dihydroxybenzene- 3,5-disulfonic acid, resorcin, etc. are oxidized upon the concns. of cobalt ions. CONSTITUTION:For example, a sample is drawn into a 10-20ml beaker and 1ml a sodium tartrate as a masking agent and a sodium hydroxide soln. of 9.8pH as a buffer are put therein, thence 1ml 1,2-dihydroxybenzene-3,5-disulfonate (0.15mol/l) and 1ml hydrogen peroxide (0.25mol/l) are added to these. After 5min, the absorbancy of 440nm is measured. While large absorption is observed on the wavelength side shorter than 340nm with the sample contg. no cobalt, the absorption shifts to the long wavelength side and new absorption appears at around 440nm when cobalt is contained therein. Hence, it is possible to know the concn. of cobalt by measuring the absorbancy of the constant wavelength around 340-550nm.

Abstract: PURPOSE:To output information for detecting a motion vector or the motion vector itself by providing a means for finding the angular displacement between frames in the direction of an image pickup device to the image pickup device which outputs an image signal. CONSTITUTION:The object image area 20 of a last frame and the object image area 21 of a current frame are inputted to and converted photoelectrically by the image pickup device 1, which outputs the image signal.

Title: Method of filling bathtub with hot water in automated bath device
Inventor: KAWAI MASAAKI
IPC: F24H1/46
Filed: 1989-02-28
Abstract: PURPOSE:To increase the flow rate of hot-water to be poured by pouring the hot-water by opening a solenoid valve after a flow rate control valve upon pouring the hot-water, and detecting an output from a pressure sensor to gradually increase the opening of the flow rate control valve only when the output from the pressure sensor is a maximum measureable pressure, and further pouring the hot-water at the flow rate within the maximum measureable pressure. CONSTITUTION:Once a hot-water pouring switch is turned on after a water level is set to a controller, a solenoid valve 6 is opened in a state where a flow control valve 16 is drawn to start the pouring of the hot-water. At this time, an output from a pressure sensor 7 is monitored to judge whether or not the output is less than the maximum measureable pressure of the pressure sensor. In the case where the output is less than the maximum measureable pressure, the degree of opening of the flow control valve 16 is gradually increased, and the degree of the opening of the flow control valve 16 is determined such that the flow rate is less than the errosion limit of a flow line within the measurement range of the pressure sensor 7. With this degree of the opening kept as it is, the output of the pressure sensor 7 is monitored while the hot-water is poured to a set water level. In such a manner, the water level in a bath tank is detected while the hot-water is successively poured. Once the pressure sensor 7 detects a fact that the bath water level reaches a minimum flow rate, the flow control valve 16 is reduced to the minimum flow rate, and thereafter the solenoid valve 6 is closed. Thereby, water pouring time can be shortened while protecting the pressure sensor.
