Title: Battery power supply circuit
Inventor: MAEDA SUSUMU
IPC: H02J9/00
Filed: 1990-08-15
Abstract: PURPOSE:To obtain a small-sized, simple-structured and highly reliable battery power supply circuit in which a battery is not completely discharged due to a latchup phenomenon by controlling the supply of backup current to a microprocessor. CONSTITUTION:When a latchup phenomenon presents in the CPU 3 due to some reason, a power circuit for backup 6 supplies the increased quantity of power, causing an excess current and then a large voltage drop in a resistor 20. As a result, current supply to a transistor TR4 through a diode D2 and resistor R21 is stopped. Turning off of an ignition key switch causes a voltage drop in a power circuit for drive 8 and thus stops current supply to the transistor TR4 through a diode D1 and resistor R22. Consequently, the transistor TR4 gets into the off state and power supply to the CPU 3 is stopped and finally the latchup phenomenon in the CPU 3 disappears. In addition, a battery is not completely discharged since a very small amount of power is supplied from the battery.

Abstract: PURPOSE:To make it possible to surely carry out a predetermined paper feed in a paper feed means provided therein with a plurality of paper feed ports, by setting a priority paper feed port among them so that thus set priority paper feed port is surely selected even in an automatic paper selecting mode. CONSTITUTION:Priority paper feed port set keys 503, 504 which are switches for designating a priority paper feed port, designate a priority paper feed port which has been set when a power source is turned on. In such a case that no priority paper feed port has been set when the power source is turned on, if it is determined that a first paper feed port is selected when a paper selecting switch is turned on, a second paper feed port is selected and the paper size code thereof is inputted. If paper runs out during copying operation with the use of an automatic paper feed cassette 20 through the first paper feed port, it is judged whether the size of paper in an automatic paper feed cassette 20 through the second paper feed port is suitable or not, and if it is suitable, copying operation is continued.

Filed: 1989-08-24
Abstract: PURPOSE:To eliminate the need for prescribed polarization extracting means, such as analyzer, on a photodetecting side by propagating only one polarization mode of two polarization modes orthogonal with each other. CONSTITUTION:The fiber has a core 11, a 1st clad 12 which is formed on the outer periphery of the core 11 and has the refractive index lower than the refractive index of the core 11 and a 2nd clad 13 which is formed on the outer side of the 1st clad 12, has the refractive index higher than the refractive index of the 1st 12 and has the refractive index lower than the refractive index in the central part of the core 11. The sectional shape of the core 11 is made into a noncircular shape. Since the width of the groove of the 1st 12 varies substantially in two directions, the propagation constant of the one polarization mode of the two polarization modes orthogonal with each other is larger than the propagation constant of the clad and can be propagated. The other polarization mode is smaller or equal in the propagation constant thereof than or to the propagation constant of the clad and the wavelength region to attain the cut off state exists therein. The need for the prescribed polarization extracting means, such as analyzer, is eliminated in this way.

Title: Pipe for heating medium-circulation
Inventor: NAKAJIMA MASATSUGU
IPC: E01C11/26
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a pipe capable of resisting against a snow melting agent and enhance the workability by constituting the pipe with an outer layer made of heat-resistant synthetic resin, an inner layer made of a chemical-resistant synthetic resin and an adhesive layer provided between the outer layer and the inner layer. SOLUTION: A heat medium circulating pipe 1 is constituted with an outer layer 3 made of a heat-resistant synthetic resin, an inner layer 2 made of a chemical-resistant synthetic resin, and an adhesive layer 4. Next, a concrete layer is laid on a foundation subbase, grille-shaped steel wire is arranged on the concrete layer, the pipe 1 is laid, and high-temperature asphalt is poured while flowing cooling water through the pipe 1 thereby forming the asphalt layer. Next, even though such high-temperature asphalt is poured, the outer layer 2 is not deformed, thus the cooling to the minimum temperature for laying asphalt is not required any more and the work can be simplified.  Then, even though the outer layer 2 is invaded and cracking occurs by a snow melting agent sprayed to the layer finished with asphalt, the inner layer 3 will never be corroded and warm water passing through the inside of the pipe 1 will never be leaked out thereby permitting the use of this pipe for many years.
