A near-beta titanium alloy having higher strength than ‘Ti-17’ is provided, while suppressing cost increase. Such a near-&bgr; titanium alloy consists of, in weight percent, 0.5-7% of V, 0.5-2.5% of Fe, 0.5-5% of Mo, 0.5-5% of Cr, 3-7% of Al, and the balance of Ti and impurities. When the weight % of V content is expressed as XV, the weight % of Fe content is expressed as XFe, the weight % of Mo content is expressed as XMo, and the weight % of Cr content is expressed as XCr; the value of XV+2.95XFe+1.5 XMo+1.65XCr is 9-17%.

A glass layer 3 is disposed between a glass member 4 and a thermal conductor 7 along a region to be fused. The glass layer 3 is formed by removing an organic solvent and a binder from the paste layer while using the thermal conductor 7 as a hotplate. Then, a laser beam L1 is emitted while using the thermal conductor 7 as a heatsink, so as to melt the glass layer 3, thereby burning and fixing the glass layer 3 onto the glass member 4. Thereafter, another glass member is overlaid on the glass member 4 having the glass layer 3 burned thereonto, such that the glass layer 3 is interposed therebetween. Then, the region to be fused is irradiated therealong with a laser beam, so as to fuse the glass members together.

A flash water heater using a heat pump includes a heat exchanger in which a refrigerant flow path exchanges heat with a water flow path. Tap water is led directly to the water flow path, and hot water supplied from the water flow path is used. The water heater includes at least one of the following elements: 1) a load setter for setting a heating amount in the heat exchanger, and a heating controller for regulating a heating amount in response to an amount set by the load setter; 2) a heater for heating water flowing through the water flow path in the heat exchanger and water flowing the path before and after the heat exchanger; 3) plural compressors; and 4) plural heat-pump cycles. The water heater is excellent in start-up of hot water temperature when the hot water supply starts, controllability, and efficiency.

A polishing method includes the steps of: (a) polishing a to-be-polished object by moving an abrasive cloth relative to the to-be-polished object while pressing the to-be-polished object against the abrasive cloth; and (b) pressing a dressing member against the abrasive cloth moving relative to the to-be-polished object with the to-be-polished object pressed against the abrasive cloth and relatively moving the abrasive cloth and the dressing member, thereby dressing the abrasive cloth while polishing the to-be-polished object. The difference between the torque current of a motor in the step (a) and the torque current of the motor in the step (b) is determined, and when the determined difference falls below a previously set value is detected.

A process for making a work piece from a β-type titanium alloy material includes subjecting the β-type titanium alloy material to cold working with controlling the reduction rate thereof to vary the reduction rate depending on a position across a plain direction of the β-type titanium alloy material, and then subjecting the β-type titanium alloy material to an aging treatment.
摘要:
The present invention relates to a microactuator that can be produced by utilizing the IC fabrication processes such as etching, lithography or the like and that can be used as a micropositioner in a multi probe head for scanning probe microscopy and a pickup head for recording and reproducing equipment. The microactuator comprises a plurality of electrodes arranged around the circumference of a circle, a ring-like displacement plate located inside said electrodes, beams which support said displacement plate elastically at one ends and at the same time are fixed at the other ends to a point located towards the inside of said displacement plate on a substrate and a voltage supply means to apply voltages to said electrodes in order for said electrodes to attract said displacement plate electrostatically. An extremely small, long life and high reliability microactuator that is excellent in mass-producibility and capable of high precision positioning can be realized.
