摘要:
A pattern formation apparatus has a drum-like intaglio rolling along a transferred medium. After the intaglio is charged by a charger, a pattern of toner particles is formed by supplying a liquid developer of each color to the intaglio via a developing machine and an electric field is formed between the intaglio and the transferred medium by rolling the intaglio along the transferred medium to transfer charged toner particles to the transferred medium. A cleaning apparatus which cleans the intaglio after the pattern in each color being transferred to the transferred medium has nozzles at an angle for blowing a cleaning liquid against recesses and removal rollers for removing toner particles liberated from the recesses together with the cleaning liquid.

A pattern forming apparatus includes an intaglio having a pattern of depressions, developing units which form a first potential difference with the intaglio, supply a liquid developer containing charged phosphor particles to the pattern and develop by aggregating the phosphor particles in the depressions, and a transfer roller which forms a second potential difference with the developed intaglio and a glass sheet arranged in opposed relation to each other and sequentially transfers the phosphor particles aggregated in the depressions to the glass sheet.
摘要:
By using an intaglio plate for holding a pattern formed by a developing agent, a transfer device for transferring patterns developed on the intaglio plate to a transfer object medium, and a baking chamber for eliminating an electrode layer after transfer or heightening resistance thereof, the patterns developed on the intaglio plate are transferred onto the electrode layer disposed at the opposite side of the transfer object medium, and then heated in the baking chamber, whereby the electrode layer is eliminated or heightened in resistance.

A liquid developing agent includes a toner particle having a nuclear particle and a covering layer containing a wax, provided on the surface of the nuclear particle in which the wax has at least one of polar groups and aromatic substituent groups, is substantially insoluble in an electric insulation solvent at room temperature, has a melting point below a boiling point of the electric insulation solvent, and is dissolved in the insulation solvent at a temperature higher than the melting point.

A heat exchanger, for motorcycle use and mounted on a motorcycle and in which heat is exchanged between air and a heating medium flowing inside the heat exchanger, is characterized in that: the heat exchanger is fixed to a motorcycle body via a bracket 8; the bracket 8 includes a through-hole 80 into which a portion of the motorcycle body is inserted via a cylindrical grommet 9 and collar 10 capable of being elastically deformed; a cylindrical burring portion 81, which protrudes onto one side, is formed in an inner circumferential edge portion 80a of the through-hole 80; the grommet 9 is inserted into the through-hole 80 so that the grommet 9 can be contacted with the inner circumferential edge portion 80a of the through-hole 80; and a forward end portion of the burring portion 81 is directed outside in the radial direction with respect to the inner circumferential edge portion 80a of the through-hole 80.

The present invention provides a die-casting method comprising the steps of evacuating a cavity 30 defined by dies of a die-casting machine to provide therein a vacuum of 100 millibar or less during a first period, injecting a reactive gas from a sleeve of the die-casting machine into the cavity 30 during a second period which has a partial overlap period with the first period and follows the overlap period, so as to increase the inner pressure of the cavity to atmospheric pressure or more, pouring a molten aluminum alloy M into the sleeve 40 while keeping the injection of the reactive gas, and subsequently moving a plunger 42 in the sleeve forward to forcibly inject the molten aluminum alloy from the sleeve into the cavity 30 while re-evacuating the cavity 30. The evacuation, reactive-gas injection and re-evacuation operations can be performed with respective overlap periods therebetween. During the operation of supplying the molten aluminum alloy, air and water are effectively discharged to outside, and the reactive gas in an unreacted state is discharged to outside without being incorporated into the molten aluminum alloy. Thus, the present invention provides a die-cast product having a significantly reduced volume of incorporated gases and allows the die-cast product to be applied to functional members.

In an oil cooler, a heat exchange core is housed in a casing including a cylindrical sidewall part in a way that a cooling water passage is formed around a heat exchange core. The heat exchange core includes inlet-side and outlet-side oil passages, and enables oil to be delivered from the inlet-side oil passage to the outlet-side oil passage. Inlet and outlet pipes are connected to the sidewall part. The inlet pipe forms a cooling water inlet passage in communication with the cooling water passage. The outlet pipe forms a cooling water outlet passage in communication with the cooling water passage. Outward of the inlet-side oil passage, an outwardly swelling part is formed in the sidewall part of the casing. This arrangement avoids the oil cooler being constructed in a large size and avoids decreasing the heat exchange efficiency of the oil cooler, and also prevents cavitation and erosion from occurring due to the flow of cooling water in an area corresponding to the inlet-side oil passage.

摘要:
A controlling member (a controlling pin 10) is inserted through an insertion hole 7 of a mold 1 and projected into a cavity 6. After a pipe P as an insert member is arranged at a predetermined position in the cavity 6, the pipe P is held in the cavity 6 by inserting a tip of the controlling pin 10 into a hole h of the pipe P at the end p1, or by inserting the end p1 of the pipe P into a cave 21 of the controlling member. A molten aluminum alloy is then poured through a gate 5 into the cavity 6 under such the condition, to enclose the pipe P with the aluminum alloy. Dislocation of the pipe P caused by kinetic and thermal energies of the poured aluminum alloy is suppressed by the controlling pin 10 or block 20 at the end p1. Since the enclosed pipe P has its end p1 opened at a predetermined position, a cast product obtained in this way can be used as a brake caliper or the like having an inner hydraulic circuit.
