Title: Fault locating system
Inventor: YONEMOTO SHINICHI
IPC: H04B17/40
Filed: 1982-09-16
Abstract: PURPOSE:To attain the fault locating without stopping signal from a counter terminal station device, by blocking a signal transmitted from the counter terminal station device in a relay device, when a monitor signal is transmitted to the relay device from a terminal station device. CONSTITUTION:Peak detecting circuits 121, 131, comparators 122, 132 and gates 123, 133 are provided in a monitor section 10. A signal transmitted from a gate 74 of a discriminating section 71 to the monitor section is set to a flip- flop 102 via a gate 101, transmitted to a filter 104 and also to a peak detecting circuit 121. The comparator 122 compares a received peak value with a set value and the gate 123 is opened at a preset value or over. When a monitor signal is transmitted in this case, an output from the comparator 105 blocks a gate 76 of the discriminating section 72 via the gate 123 so as to prevent a signal transmitted from an equalizing amplifier shown in Figure from being transmitted to a reproducing section 91.

Title: Chassis dynamometer for electric automobile
Inventor: SHIMIZU KENICHI
IPC: G01M17/007
Filed: 1995-06-05
Abstract: PURPOSE: To faithfully evaluate regenerative braking function in a wide application range by providing a chassis dynamometer for a four-wheel drive and letting it simulate a regenerative braking as brake dynamometers for the four wheels in a decelerating mode. CONSTITUTION: The chassis dynamometer 1 for electric automobile is constituted of a chassis dynamometer composed of two rollers 12, 13 and dynamometers 14, 15, a temperature adjuster 5, and two battery simulators 4 to secure resolution of load control, realize larger real inertia, and secure space efficiency.

Title: Magnetic disk cartridge
Inventor: KOYAMA MASARU
IPC: G11B33/14
Filed: 1983-09-02
Abstract: PURPOSE:To prevent occurrence of a dew condensation phenomenon and to improve reliability by inserting a dehumidifying agent to the inside of the cover and by retaining the relative humidity inside the cartridge case lower. CONSTITUTION:A through hole 12 for air flow is provided on a separator 11, and a dehumidifying agent 13 is provided. For the internal condition of a cartridge case 2, the temperature is set as T1 and the relative humidity as X%. The temperature lowers to T2 and the relative humidity approaches to 100% by increasing during the storage. Although the relative humidity is higher than the original point, it retains the lower point than 100% by the dehumidifying effect of the dehumidifying agent 13. Thus, the relative humidity does not exceed 100%. Since a corroded substance 10 does not occur, a device with high reliability, which is free from the head crash accident, can be obtained. By sticking the dehumidifying agent 13 to the separator 11, the contact accident of the dehumidifying agent 13 and the cartridge case 2 is eliminated.

Title: Circuit for high-speed driving of light source by cmos technique
Inventor: BUARUTERU BERA
IPC: H01S5/042
Filed: 1995-06-06
Abstract: PURPOSE: To provide a circuit which enables a high speed drive of a laser diode and efficiently operates at a speed meeting requirements given by an optical fiber communication system to avoid interference between an optical source drive current and bias current. CONSTITUTION: When a data transmitting source feeds a drive current to the input I of a cascade of CMOS inverters, this cascade can be driven by the cascade of inverters having characteristics about the size of p- and n-type CMOS transistors at a speed enough for the input capacity of transistors SM. When the voltage is at a low logic level on the input I, the gate of MS goes to a high logic level to cut off the p-type transistor and only a bias current fed from MP flows to a terminal L. The current flowing to this terminal L is given by addition of the bias current to a modulating current fed from MM, and both currents depend on a voltage fed to terminals M and P but are mutually independently adjustable.

Title: Cracking method of semiconductor substrate
Inventor: TANIZAKI AKINORI
IPC: H01L21/78
Filed: 1978-12-23
Abstract: PURPOSE: To split a semiconductor substrate satisfactorily by a method wherein the substrate having a scribed groove is sandwiched in between plastic films and difference in air pressure is provided between both sides.  
     CONSTITUTION: A substrate 2 having a scribe groove 1 on the under surface is sandwiched in between 2 sheets of pressure sensitive adhesive plastic films 3, 3' removing air bubbles. After placing the films 3, 3' between a vessel 5 and a lid 7 simultaneously discharging air 4, 6, the air is gradually introduced 6 into the lid side 7, then the substrate is divided into chips 8 because the films are curved. This constitution prevents the chips from being broken and damaged because no pressure is added by a hard roller.

Title: Hot-water mixing controller
Inventor: UEKI KOICHI
IPC: F16K31/64
Filed: 1984-07-31
Abstract: PURPOSE:To permit the sharp rise of the temperature of supplied hot-water to a set value by outputting a signal for stopping the operation of a driving means into an urging-amount setting means when the amount of supplied hot-water reduces below a prescribed value. CONSTITUTION:An urging-amount setting means 22 urges a driving means 13 until the temperature difference detected by a difference detecting means 21 becomes zeor. When a user does not require the supply of hot water and a cock is closed, a flow-rate detecting means 17 detects the flow rate less than a prescribed value, and a signal to stop the operation of a driving means 13 is outputted from a flow-rate judging means 23 to the urging-amount setting means 22. Even if the user abruptly opens the cock, the user is protected from the danger of using hot-water, since a mixing valve is at the position close to that for the supply of the hot-water having the temperature set in the preceding time.

IPC: B21C49/00
Filed: 1992-05-28
Abstract: PURPOSE:To exactly detect buckling of a strip in an early stage by executing rotated speed control of a tower pinch roller, based on a detected strip displacement or/and speed difference. CONSTITUTION:Based on a plate speed of a strip 6 measured by a plate speed detector, a speed difference between its plate speed and a peripheral speed of a tower pinch roller is derived by an arithmetic circuit. In the case displacement of the strip exceeding a reference value is detected in an inlet of a guide device 7 by a non-contact type displacement sensor 11, or the speed difference exceeds the reference value, a buckling alarm of the strip is raised. Also, based on a detecting signal, rotating speed control (rotating speed correction) of the tower pinch roller is executed. In such a way, prevention of buckling and stabilization of a plate winding form of a loop coil can be realized.

Title: Organic electroluminescence element
Inventor: SATO YOSHIHARU
IPC: H05B33/12
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To improve heat resistance, stabilize a driving characteristic and improve blue luminescence by including aromatic amine compound having a triazine skeleton in a positive hole transport layer which is held between an anode and a cathode on a substrate and is provided together with an electron transport layer. SOLUTION: This aromatic amine compound is shown by a formula and has a glass transition temperature of 85 deg.C or more. Therefore, because a positive hole transport layer can be made an amorphous thin film which is difficult to be crystallized and molecular mutual dispersion with an electron transport layer can be suppressed even at 85 deg.C or more, a luminescence characteristic and heat resistance of an element are simultaneously improved. A positive hole transport luminescent layer which shows strong fluorescence and exists in an area of 400 to 600 nm in fluorescene maximum becomes possible and further, compound which shows blue luminescene can be synthesized by a proper molecular design.  In the formula, all of Ar<a> to Ar<f> : aromatic hydrocarbon groups or aromatic heterocyclic groups; X<a> to X<c> : bivalent aromatic hydrocarbon groups or bivalent aromatic heterocyclic groups are independent each other and may have substitutional groups.
