Title: Electrical rust preventive system for piping
Inventor: ONUMA NAOKUNI
IPC: F16L58/02
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of rust in piping and appliances for feed water, hot water supply, ground water, etc., and to prolong the life of piping equipment by stopping the red water of city water, etc. SOLUTION: This system comprises an electrode part 2 with a limiter for energizing the water in the metallic piping 1 for feed water with a DC slight current (8 to 26 mA), a current controller 3 for supplying a slight current (25 to 150 mA) to the electrode part 2 and a ground 4 connected to the piping 1. The current controller 3 is connected to a general AC power source 5 and allows the connection of the ground 4 as well. The electrochromic part 2 is mounted to be exposed in the water passage hole in the central part of a disk- shaped insulative electrode holder held between the flanges 6 of a piping juncture in such a manner that the electrode comes into contact with the water.  The piping is replenished with electrons by the energization of the slight current from the electrode, by which the ionization of the metal is prevented and the generation and progression of the rust over the entire part of the feed water piping equipment are suppressed. Since the current is extremely slight, no adverse influences are exerted in work, actual life and the human body at all.

Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To improve operational performance of a 3-transistor type DRAM by reading out amplified memory cell information through a read-bit line, writing it in a memory cell through a write-bit line, and refreshing information. SOLUTION: When a device is in a non-operation state in which writing operation and reading operation for a memory cell 16 are not performed, a pre-charge circuit 12 is made an ON state, and a write-bit line WBL and a read-bit line RBL are both pre-charged to a power source potential of the same potential. Writing operation for the memory cell 16 makes the pre-charge circuit 12 an OFF state, and stops pre-charge to the write-bit line WBL and read-bit line RBL. After that, a column selecting line Y and a write-word line WWL are made a high level, writing data inputted from an inverse data line DL through NMOS 30a, 24a is written in an accumulation node C.

Title: Train operation control system
Inventor: KOO HIDEO
IPC: B60L15/32
Filed: 1989-08-02
Abstract: PURPOSE:To carry out efficient operation by sequentially switching motive power units when a train composed of a plurality of motive power units having main motor or drive controller and a plurality of accompanied cars reaches to a constant speed. CONSTITUTION:A train is composed of two motive power units 1, 2 having main motors 1a, 2a or drive controllers 1b, 2b and two accompanied cars 3, 4.

In this condition, a piston rod 15 is pulled out to enlarge a space between a partition wall 18 and a piston 14 so that a valve 11 is opened while a valve 12 is closed, and accordingly, a depressurizing chamber A and the pipe line 7 are depressurized. Further, the piston rod 15 is pushed in to narrow the space between the partition wall 18 and the piston 14 so that the valve 11 is closed while the valve 12 is opened, and accordingly, a pressure rising chamber B and the pipe line 8 are pressurized. The patterns of variations of the pressure gages 3, 4 are obtained after a predetermined elapses from the depressurization or the pressurization. Thereby it is possible to easily detect a sealing performance of the pump in the air.

Patent JP-H1047966-A (JP)
Title: Angular velocity sensor
Inventor: TOUGE TADASHI
IPC: G01C19/5719
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To improve the detecting accuracy of an angular velocity sensor and to easily adjust the resonance frequency of a vibrating electrode by providing a vibrating body which vibrates in both the x- and z-directions, an exciting means which vibrates the vibrating body in the x-direction, fixed and mobile electrodes which are oppositely faced to each other in the z-direction, and a mobile electrode supporting means which transmits vibrations to the mobile electrode on a pedestal. SOLUTION: When an angular velocity is applied to a vibrating plate 6 around the y-axis while the plate 6 vibrates forward and backward in the x-direction, the plate 6 makes elliptic vibrations in parallel to the x-z plane around the y-axis. When the plate 6 vibrates, a mobile electrode 7 vibrates in the z-direction. When a z-direction vibrating component is generated owing to an angular velocity applied to the plate 6, the capacitance between the electrode 7 and a fixed electrode 8 oscillates. When the resonance frequency of the electrode 7 matches the exciting frequency of the elliptic vibrations, the amplitude of the z-direction vibrations of the electrode 7 becomes larger and the angular velocity detecting resolution of an angular velocity sensor becomes higher.  Since the plate 6 and electrode 7 independently vibrate and the adjustment of resonance frequencies of the plate 6 and electrode 7 is performed individually, the adjustment of the resonance frequency of one side does not affect much the resonance frequency of the other side.

Abstract: PURPOSE:To enable discrimination between an abnormal level and a normal level at a glance by a display color, by using a multicolor light emitting element as a display element and by making the display color different between a case when the abnormal level is displayed and a case when the normal level is displayed. CONSTITUTION:A multicolor light emitting element is used as a display element and a display color is made different between a case when an abnormal level is displayed and a case when a normal level is displayed. Concretely, a display control circuit 1 controls the display of the multicolor light emitting element 2 on the basis of an output signal of a level setting circuit 4. A signal for indication display is inputted to an input circuit 5 according to an input signal 6. Based on the inputted signal, an A/D conversion circuit 3 outputs an output value being proportional to the input. In the bar graph display, for instance, a display 11 when the value is a lower-limit set value or below in relation to the input signal 6 or a display 13 when it is an upper- limit set value or above are colored with red or orange to show abnormality. A display 12 in the case when the value is above the lower-limit set value and below the upper- limit set value is colored with green to show normality. According to this constitution, discrimination between the abnormal level and the normal level can be made at a glance on the basis of the display color.
