Title: Fading discriminating processing system
Inventor: SUZUKI HIROYOSHI
IPC: H04B17/00
Filed: 1982-08-17
Abstract: PURPOSE:To discriminate a substantial failure from the effect due to fading, by applying Fourier transformation to an alarm signal in a certain time, and obtaining an approximate value of a frequency representing the peak value of a spectrum. CONSTITUTION:An alarm signal from radio devices RA-RC is detected at a sensor SEN and transferred to a computer CPU in a monitor station SV. The CPU summarizes the alarm signal for a prescribed time T from that point of time so as to discriminate a failure when the generation/restoring information of the alarm signal from the SEN is inputted. When the generation/restoration of the alarm signal continues, the next summarizing is performed from the time of generation/restoration time of the alarm signal just after the 1st summarization. The CPU counts the generation/restoration number of times (n) at each alarm after the end of each summarizing time so as to obtain n/2T. This value is compared with a prescribed value (f), and when the generation of alarm at the end of summarization, it is assumed as the fading in case of f<=n/2T and as the generation of a failure in case of f>n/2T.

IPC: C25D7/12
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To form wiring, or the like, which obviate the generation of voids and seams, and have reliability by stirring a plating liquid contg. a material reduced by the potential nobler than a reduction potential on a body to be plated with plating metal ions by using the liquid described above. SOLUTION: The plating liquid is formed by incorporating the material reduced by the potential nobler than the reduction potential on the body to be plated with the plating metal ions, such as copper, at a concn. of about 0.0001 to 1 mol/l into the liquid. The amt. of the material reduced by the potential nobler than the potential of the plating metal included in the plating liquid or the reductant thereof, which is included in the plating metal deposited on the surface of the body to be plated, is preferably <=10 ppm. The plating liquid is stirred by blowing gas during the course of executing plating by using this plating liquid or by using a stirrer.  The additive material effective when the plating liquid is copper includes materials, such as hydrogen peroxide, ammonium persulfate and benzoquinone, which are nobler in the reduction potential than the potential of the electrodeposition of copper.

Title: Restart valve device
Inventor: SHIMIZU SEIICHI
IPC: F02M5/12
Filed: 1979-11-06
Abstract: PURPOSE: To obtain an improved restart of an internal combustion engine by constructing the restart valve device in a fuel supply device such that a large amount of fuel is recirculated into a tank under atmosphere of a predetermined high temperature, thereby preventing a bubble-containing fuel from entering into a float chamber.  
     CONSTITUTION: The fuel within a fuel tank T is usually supplied under pressure by a fuel pump P to a float chamber 7 through a fuel supply passage 1, a fuel inlet of a restart valve 2 and a fuel outlet opened and closed by a float valve 5. At this time, an extra amount of fuel is recirculated into the tank T through an orifice 9 and a return passage 10. On the other hand, when the engine operation is stopped under the atmosphere of a high temperature and restarted, a fuel temperature sensor 17 detects a high temperature to be turned on. As a result, a relay is turned off so as to de-energize a solenoid 13, so that a releasing valve 8 descends owing to the force of a spring 19. Accordingly, a bypass passage 10A is opened and at the same time, the fuel outlet 6 is closed. Thus, the bubble-containing fuel at high temperature is quickly recirculated into the tank T.

Abstract: PURPOSE:To prevent an interfacial layer with low permittivity at an interface between an insulating film and an electrode, by using a capacitive-element electrode made of metal, of which an oxide film is made of an insulating substance with permittivity larger than a given value. CONSTITUTION:In a capacitive element, a lower electrode 2 made of 100nm tantalum(Ta), a first insulating layer 3 made of 5nm tantalum pentoxide (Ta2O5) with permittivity of 25, a second insulating layer 4 made of 25nm tantalum dioxide (TiO2) with permittivity of 100, and an upper electrode 5 made of 100nm titanium nitride (TiN) are formed on a silicon substrate 1.

The electrode in the capacitive element is preferably made of metal with a smaller absolute value of oxide generative free energy than that of the metal that constitutes the oxide insulating substance.

Title: Device for maintaining parallelism of cross rail of gate-type machine tool
Inventor: ETOU GOROU
IPC: B23Q1/26
Filed: 1978-11-22
Abstract: PURPOSE:To perform machining with high accuracy, by always accurately maintaining the degree of parallelism of a cross rail to the top of a table even if the cross rail is repeatedly moved up and down. CONSTITUTION:When a cross rail 6 is repeatedly moved up and down, the degree of parallelism of the cross rail to a table 2 falls. The fall is detected in terms of the difference between two values shown on an indication unit 36 and corresponding to the levels of the right and left ends of the cross rail 6. The end of the cross rail 6 having deviated down as to the top of the table 2 is lifted by an adjuster 37 or 38 in response to the detection of the fall so that both the indicated values coincide with each other. The cross rail 6 is thus kept parallel with the top of the table 2. This leads to plane machining with very high accuracy of micron order.

Abstract: PURPOSE:To reduce the number of parts and to prevent the degrading in the accuracy of the mounting of a detection piece by forming a mirror holder to hold the moving mirror of an exposure light source and the detection piece to operate a position detection means together on a scanning moving member which is an integral body. CONSTITUTION:The exposure light source unit 40 and the movable mirror unit 80 wait in a starting position preceeding the starting of a scanning exposure; the unit 40 is accurately positioned in its home position HP by an optical position detection means 72. The tip of the flat part of the mirror holder 71 bent outward exists between the light emitting part and the light-receiving part of a means 72, and functions as a light shielding piece 71a to shield light, and this status in which the light is shielded is the start-waiting status of the unit 40.
