Abstract: An electrical device such as a power control apparatus comprises a case and at least one electrical component accommodated in the case. The case has a flow path for a cooling fluid. The flow path is formed between a bottom portion and a cover. The flow path is elongated generally along a U shape. The bottom portion and the cover are joined by welding. The cover is formed with protruding portions protruding into the flow path. The protruding portions have shapes to reduce stress concentration on welding portions. A stress caused by a pressure of the cooling fluid may acts on a distal end formed inside of the U shape in a concentration manner.

Abstract: A fuel heating device comprises a heater housing (7) including a bottom wall (17), an upper inlet opening (13) provided in an upper part of the heater housing and an outlet opening (18) provided in a lower part of the heater housing diametrically opposite to the inlet opening, and a heater member (9) including a heat emitting portion (9h) received in a middle part of a heating chamber (6) defined by the heater housing. As the inlet opening is provided in an upper part of the fuel housing, bubbles that may be created by the vaporization of the fuel heated by the heater member is allowed to rise upward and then escape out of the inlet opening. The bubbles that have returned to the fuel supply passage (4) are cooled by fresh fuel, and condense to liquid state once again. Therefore, the heater housing and fuel supply passage are kept free from the presence of fuel vapor, and the fuel therein can be pressurized by a fuel pump to a proper level at all times.

Abstract: A coin discriminating apparatus includes light emitting elements for emitting light toward one surface of a coin being transported, a line sensor for photoelectrically detecting light reflected by the one surface of the coin and producing image pattern data of the one surface of the coin, a reference data memory for storing reference data of coins of each denomination, a preliminary denomination discriminator for calculating a diameter of the coin based on the image pattern data of the one surface of the coin produced by the line sensor, comparing the thus calculated diameter of the coin with reference diameter data of coins of each denomination and preliminarily determining the denomination of the coin, and a denomination discriminator for reading reference pattern data of coins of the denomination determined by the preliminary denomination discriminator from the reference data memory, comparing the thus read reference pattern data with image pattern data of the one surface of the coin and finally determinin

Abstract: An automatic money depositing and disbursing machine has functions of receiving bank notes from a transacting port and feeding the same through a discriminating section provided in a note circulating delivery passage and accommodating in boxes normal notes judges by the discriminating section, and of disbursing the notes through the discriminating section from the transacting port. The machine is of such a construction that at least portions of the received notes are used as notes to be defrayed or disbursed. The boxes are adapted to be removably supported on the stacker supporting device. The stacker supporting device comprises a rail portion attached to the bottom of the machine and a movable portion adapted to accommodate the boxes therein and slidably supported on the rail portion in horizontal opposite directions.

The machine is of such a construction that at least portions of the received notes are used as notes to be defrayed or disbursed. Provided between the note circulating delivery passage and the boxes are note transfer mechanism which comprises at least one upwardly retraction accumulating wheel for feeding notes into the boxes from the note circulating delivery passage and at least one pair of attracting drums for sucking notes from the boxes and feeding them to the note circulating delivery passage. The machine has a judging section for checking a near-end condition.

Abstract: An automatic money receiving and disbursing machine having the functions of receiving money from customers and disbursing money to customers from a box disposed within the machine. The machine is provided with a circulation path in communication with a transacting section to receive or disburse the notes therethrough. A portion of the circulation path is in communication with the disbursing box for receiving the notes disbursed from the disbursing box. Another portion of the circulation path is in communication with a note receiving box. A discrimination section is provided in the circulation path to discriminate the notes received or the notes disbursed. In the disbursing mode, when an abnormal note is found by discrimination, all the notes are discriminated again by passing the notes through the discrimination section via the circulation path.

Abstract: An automatic money receiving and disbursing machine has two dealing openings through one of which the notes are received in the machine or disbursed from the machine. A discriminating section is provided for discriminating the received notes or the disbursed notes. Discrimination made through the discriminating section is made in a high grade or in a low grade. Two accumulating sections are provided between two dealing openings on a delivery section. These accumulating sections are used to temporarily store the notes. A receiving and disbursing box is provided for receipt of a specific kind of note. A disbursing box and a reject box are also provided.
