Title: Rolling bearing device
Inventor: TAKADA HIROTOSHI
IPC: F16C35/073
Filed: 1985-02-06
Abstract: PURPOSE:To prevent any creep from being produced due to a temperature change by subjecting both flat surfaces of a distance piece having a linear expansion coefficient approximately equal to a partner member and a railway surface to tapered engagement, while forming a low melting point coating layer on a fit surface of at least one of said surfaces. CONSTITUTION:Both flat surfaces of an inner race 1 respectively form a tapered surface 51 opening outwardly with respect to a bearing center O, with which tapered surface 11 tapered surfaces 51 of a pair of distance piece 5 are engaged. The fit between the distance piece 5 and a shaft 6 is tight, and for linear expansion coefficients of both the distance piece and the shaft, those substantially equal to each other are selected. The size of an inner diameter of the inner race 1 to the shaft 6 is formed into a size to provide loose fit, and a coating layer 7 comprising low melting point metal and plastic etc., is formed on an inner race 1, whereby said distance piece and said shaft provide tight-fit or loose-fit in assembly thereof. Moreover, the distance piece 5 has therein a groove 52 for permitting the coating layer to flow out.

Title: Ink jet recording apparatus
Inventor: TSUKADA KENJI
IPC: B41J2/175
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording apparatus reducing the quantity of air bubbles remaining between a hollow supply needle supplying ink to a recording head and a filter member and capable of stably supplying ink to the recording head. SOLUTION: A projected part 22a is formed to the filter member 22 arranged to the lower bottom part of an ink supply needle 21 leading ink out of an ink cartridge 8 on the hollow part side of the ink supply needle 21. By the presence of the projected part 22a, the substantial area of the filter member 22 can be increased and the pressure loss by the filter member 22 can be reduced. Since the space where a residual air bubble Ai is present on the upstream side of the filter member 22 is occupied by the semispherical projected part 22a, the discharge of the air bubble Ai can be accelerated at a time of the initial filling operation of ink.

Title: Switching power circuit
Inventor: SEKINE YUTAKA
IPC: H02M3/338
Filed: 1986-02-03
Abstract: PURPOSE:To shorten the time up to stationary operation from the start of the application of input DC voltage by starting a converter circuit after a capacitor is charged completely. CONSTITUTION:When a capacitor C1 is charged completely, only charging currents of a capacitor C2 are used approximately as input currents, and input DC voltage Vin reaches V0. The charging of the capacitor C2 is ended at a time t2 in the graph, and start is conducted when the voltage of the capacitor C2 reaches the breakdown voltage or more of a Zener diode ZD1. Consequently, output voltage Vout which has taken zero rises and reaches a specified value, and stationary input currents flow in response to the rise of the output voltage Vout and stationary operation is started. Accordingly, a converter circuit is started after the capacitor C1 is charged completely, thus shortening the time up to stationary operation from the start of the application of input DC voltage.

Title: Cardiogonimeter method and apparatus
Inventor: ERUNSUTO ZANTSU
IPC: A61B5/04
Filed: 1983-02-12
Abstract: A cardiogoniometry or vector cardiography system wherein signals directly derived from the bioelectrical field are not directly processed as orthogonal data but are instead especially orthogonalized in an analog computing network. Orthogonalization is based on a derivation electrode configuration space with sloping sagittal and frontal planes. The orthogonalized signals are processed in a cardiogoniometer and are also jointly recorded on a commercial electrocardiograph in parallel thereto. All the represented data which can be used for diagnosis purposes are referenced to a biological zero line, which differs from the electrical neutral point. The cardiogoniometer permits a vectorial real time measurement on the patient.

Filed: 1982-02-13
Abstract: PURPOSE:To prevent useless power loss at the change of voltage set value, by dividing a power supply voltage at resistor dividing point and a connecting point between a Zener diode and a resistor and inputting the divided voltage to a lower and an upper limit detection circuit together with an output of a voltage setting device. CONSTITUTION:An output voltage VA of a voltage setting device 3 of a control system 1 is impressed to a terminal 8. The terminal 8 is connected to a voltage dividing point J1 consisting of resistors R10, R20 via a switching diode D1 to form a lower limit voltage VL, which is inputted to a comparator 6. Similarly, the terminal 8 is connected to a voltage dividing point J2 consisting of a Zener diode DZ2 and a resistor R30 for power supply voltage via a Zener diode DZ1 to form an upper limit voltage VH, which is inputted to a comparator 7. A switching diode D1 or the Zener diode DZ2 is released depending on the level of a set voltage to form a range where the lower limit value and the upper limit value does not follow the VA. Thus, in changing the set voltage VA, the output of the control system 1 does not always pass through the maximum value and approaches the set value, allowing to avoid useless power loss.
