A radiator includes: a tube through which a coolant flows; and a single tank including: a supplying chamber communicating with an end of the tube, for supplying the tube with the coolant; and a collecting chamber communicating with the other end of the tube, partitioned to the supplying chamber, and for collecting the coolant discharged from the tube.

Radiator and electronic device having the same

A cooling unit includes a tank having an inlet port and a discharge port for refrigerant, first and second radiators connected to the tank, the first and second radiators each having a flow path, an inlet chamber defined in the tank for supplying the refrigerant flowing therein from the inlet port to the first radiator, a discharge chamber defined in the tank for discharging the refrigerant cooled in the second radiator to the discharge port, and a reservoir in which bubbles generated in the refrigerant are collected, the reservoir being provided between the inlet chamber and the discharge chamber in the tank.

Cooling unit

An electronic apparatus includes: a casing; a conductive film disposed on an inner surface of the casing, the conductive film having a recess in a surface thereof; a circuit board accommodated in the casing; a semiconductor device disposed on the circuit board; and a conductive frame fixed around the semiconductor device on the circuit board, the conductive frame being fitted in the recess.

Electronic apparatus having integrated shielding film

A cooling jacket includes: first and second pipe portions through which a coolant flows; and a main portion connected with side surfaces of the first and second pipe portions, defining, with a single member, a flow path through which the coolant flows, and cooling an object to be cooled.

A repair system which prevents heating of weakly heat resistant devices together and causing deterioration of the quality when preheating a first surface of the circuit board, wherein an electromagnetic induction material is buried in advance inside the circuit board near a specific electronic device envisioned as needed repair when becoming a defective electronic device in a production process and an electromagnetic coil emitting electromagnetic waves to an electromagnetic induction member in the vicinity of the repair device is provided and the heat generated by the electromagnetic induction member due to the electromagnetic waves enables the repair device to be heated and detached from the circuit board.

Method of repair of electronic device and repair system

According to a first aspect of this invention, it is assumed that the recording is carried out on the recording medium by a non-catalyst-containing recording agent and a liquid-state catalyst is coated on the recording medium at the time of erasing processing and subsequently the heating and irradiation of near infrared rays are carried out as the erasing processing. Also, according to a second aspect of this invention, it is assumed that the recording is carried out on the recording medium by a catalyst-containing recording agent and, at the erasing processing time, the heating and irradiation of the recording agent are simultaneously carried out using a thermal emission and near IR irradiation source such as a halogen lamp.

Erasing method

Erasing method and erasing apparatus for performing that erasing method

A water-based pigment-type ink containing at least water, a pigment and a dispersant, the pigment particles having an average particle diameter of not larger than 0.1 .mu.m, the weight ratio of the pigment to the dispersant being from 1.2 to 5. The water-based pigment-type ink exhibits more excellent color tone and chroma, by adding the fluorescent pigment in an amount of from 0.1% by weight to 3% by weight with respect to the amount of the ink. Furthermore, the water-based pigment-type ink comprises at least a pigment, a high-molecular dispersant, a surfactant and water, the pigment particles having an average particle diameter of not larger than 80 nm, a maximum particle diameter not being larger than 0.1 .mu.m, the high-molecular dispersant being added in an amount of from 3% by weight to 20% by weight with respect to the amount of the ink, and the surfactant being added in an amount of from 2% by weight to 4% by weight with respect to the amount of the ink.

An ink ribbon cassette is pivotably mounted to a printer. Ink ribbon is accommodated in the ink ribbon cassette and is caused to travel by a ribbon feed roller driven by a drive shaft provided in the printer. Printing operation is carried out at the cassette end arm portion by a printing head, while the cassette end arm portion is reciprocatingly moved in the widthwise direction of the ink ribbon relative to the fixed printing head by an actuating mechanism so that a printing region of the ink ribbon is diffused and becomes wider than a printing width of the printing head. The actuating mechanism includes a small gear integral with the ribbon feed roller, a cam driven by the small gear, and a lever engaging with the cam.

One of a ribbon feed roller (32) and a pressure roller (34) for making an endless ink ribbon (30) run is displaceable relative to the other roller thereof for facilitation of replacement of the ink ribbon, and can be locked at a withdrawn position thereof. In a state where one roller is locked at the withdrawn position, mounting of the ink ribbon cassette on a printer is obstructed. Also, a running direction and an orientation of the endless ink ribbon are defined so that damage to the bonded portion of the endless ink ribbon is delayed as much as possible.

Ink ribbon cassette

An inked ribbon cassette comprising an ink supply felt, a first gear arranged in contact with the felt and a second gear in engagement with the first gear. An ink ribbon is pinched between the first and the second gears and driven by the first and the second gears upon rotation thereof. Accordingly, ink is transferred from the felt to the first gear, and in turn, from the first gear to the ink ribbon. There are grooves in the first gear for containing ink therein ink is excessively transferred from the ink supply felt to the first gear. The grooves are preferably provided in bottom lands of the first gear by increasing the whole depth of the first gear.
