摘要:
A voltage measuring circuit 11 measures a voltage of a block B1. Then, a voltage measuring circuit 12 measures a voltage of a block B2. Then, the voltage measuring circuit 11 measures again the voltage of a block B1. A low voltage CPU judges that an in-vehicle battery is abnormal if the measured voltage is out of predetermined upper and lower limits, or a voltage difference between the block B2 and the block B1 measured again is more than a predetermined value.

摘要:
The present invention is to provide a voltage detector having a common communication line for reducing a manufacturing cost. A low voltage line CPU transmits a detection instruction including an assignment of one address among a plurality of blocks. The detection instruction is branched by a transmitting bus line for concurrently transmitting to a plurality of voltage detector units. When one of the voltage detector units receives the detection instruction with the address being same as a self-address thereof, the voltage detector unit detects output voltages of unit cells and transmits the detected result to the low voltage line CPU. When the received address is not the self-address, the voltage detector unit does not transmit the detected result.

The battery control device includes: a state detecting means which acts by receiving electric power from an on-vehicle low-voltage battery having a supply voltage lower than that of an on-vehicle high-voltage battery composed of a plurality of unit cells connected together in series and detects a state of the on-vehicle high-voltage battery to monitor the on-vehicle high-voltage battery; an equalizing means for equalizing a voltage of each unit cell; and a control means which acts by receiving electric power from the on-vehicle low-voltage battery and starts to control the equalizing means in response to turning-off of an ignition switch, wherein the control means cuts electric power supply supplied from the on-vehicle low-voltage battery to the state detecting means after the turning-off of the ignition switch and before the control means starts to control the equalizing means.

An image display device includes a first substrate which has a phosphor surface, and a second substrate which is opposed to the first substrate with a gap and has a plurality of electron sources. A plurality of spacers are arranged between the first substrate and the second substrate and support an atmospheric load acting on the first and second substrates. Each of the spacers has distal end portions at the first and second substrates, respectively. The distal end portions of each spacer are impregnated with electrically conductive material and constitute conductivity-imparting portions.

A plurality of discharge resistors Rd1 to Rdn having different resistance values is provided. A CPU 72 selects one from a plurality of unit cells B1 to B16 as a connection cell and selects one resistance value according to a voltage across the connection cell from the plurality of resistance values. The CPU 72 turns on/off a cell selecting switch group 2, a polarity reversing switch group 3 and a discharge resistor selecting switch group 5 and connects the connection cell to the discharge resistor having the selected resistance value to discharge stored electric charge of the connection cell, thereby equalizing the respective voltages across the unit cells.
摘要:
A spacer structure is provided between a first substrate having a phosphor screen formed thereon and a second substrate provided with a plurality of electron emission sources. Each spacer structure has a supporting substrate, which is opposed to the first and second substrates and has a plurality of electron beam passage apertures opposed individually to the electron emission sources, and a plurality of spacers set up on a surface of the supporting substrate. The supporting substrate is formed by joining together a plurality of divided substrates. Joint portions between the divided substrates extend astride the electron beam passage apertures of the supporting substrate.
摘要:
In a flat image display device in which a first substrate having phosphor layers formed oh an inner surface thereof and a second substrate having electron emitting elements which excite the phosphor layers are located opposite each other with a gap therebetween, the plate thickness of the second substrate is made smaller than the plate thickness of the first substrate. The second substrate is formed thinner than the first substrate so that it is more flexible. Even if spacers are subject to variation in height, therefore, the first and second substrates can be securely brought into contact with the spacers, whereby gaps between the spacers and the substrates can be eliminated, and electric discharge between the first and second substrates can be restrained.
摘要:
A spacer assembly has first and second spacers standing on first and second surfaces of a plate-like grid to be integral with them. First and second molds each with a plurality of through holes are arranged on the first and second surfaces of the grid to be in tight contact with them. After that, the through holes of the molds are filled with a glass paste containing an ultraviolet-curing binder, and the glass paste is cured by irradiation with ultraviolet rays. Furthermore, while the molds are held in a tight contact state, the glass paste is calcined at a predetermined temperature. Thus, the first and second spacers are integrally formed on the grid surfaces.

Disclosed is a product carry-out apparatus for a vending machine, adapted for carrying a product, which has been delivered downward from a product housing within a vending machine body at the time of selling, in a diagonally upward and forward direction and then carrying out the product to a product take-out port. The apparatus comprises: a conveyor which is rotatable about the rear end between a forward and upward inclined position for selling and a substantially horizontal position for maintenance and, at the time of selling, at the position for selling, receives, on its upper surface, the product delivered from the product housing and carries the product in a diagonally upward and forward direction; and a support for holding the conveyor at the position for selling or at the position for maintenance. By virtue of this construction, the space defined by the product housing and the carrying mechanism can be easily increased according to need while maintaining the number of products housed in the product housing, and, thus, changing the setting of the delivery port of the product housing and the maintenance of the product housing and the carrying mechanism can be easily performed.
摘要:
A gas sensor includes a sensor element and a housing having an accommodation hole in which the sensor element is disposed. The housing has at an axial end thereof a cold crimped portion which cooperates with a shoulder portion of the accommodation hole to fixedly hold therebetween the sensor element. The cold crimped portion has an inward flange section, a hollow cylindrical section and a bent section between the inward flange section and the cylindrical section. The cold crimped portion is shaped so as to vary in thickness suddenly at or adjacent the bent section so that the cold crimped portion is assuredly bent at a predetermined position. A method of producing a gas sensor is also provided.
