    摘要： A high-pressure fuel supply pump having a fuel relief path for connecting a high-pressure fuel path downstream of a discharge valve for discharging fuel pressurized in a pressurizing chamber to a low-pressure fuel path upstream of an inlet valve or the pressurizing chamber, a check valve being provided in the fuel relief path as a relief valve for allowing the fuel to flow only to the low-pressure fuel path or the pressurizing chamber, wherein an energy attenuating mechanism is provided in a discharge path on a side facing the discharge valve upstream of the relief valve in the fuel relief path so as to prevent an instantaneous pressure rise caused in the discharge path from propagating to the relief valve.

    摘要： A time division duplex (TDD) portable telephone relay device (and TDD system employing the same) for use with a radio base station and a portable telephone terminal within a terminal building, includes first and second distributors, a synthesizer, a predetermined-size (e.g., relatively small, internal) base station section, a position detecting unit, a synchronous receive section, and an exclusive telephone line connecting unit. With such a structure, transmission/reception using a frequency channel, other than frequency channels assigned to a radio zone where the terminal building exists, is conducted between the portable telephone terminal within the terminal building and the radio base station through the predetermined-size base station section. The predetermined-size base station section executes the operation adapted to TDD based on a synchronous signal from the synchronous receive section.

    摘要： In a conventional high-pressure fuel pump, the interference fit part between a plunger and a retainer comes loose with time due to environmental factors and this reduces the clearance between the retainer and a tappet more than necessity, resulting in increase in the contact face pressure between the plunger and a cylinder when a side force acts on the plunger, which causes seizure between the plunger and the cylinder. In this invention, a protrusion protruding toward the tappet is provided around the through-hole for press-fitting the plunger, the through-hole provided in the center portion of the retainer. Since the clearance between the retainer and the tappet can sufficiently be kept even if the joint between the retainer and the plunger comes loose, the seizure between the plunger and the cylinder and the breakage of the plunger are less likely to occur even if the side force acts on the retainer.

    摘要翻译： 在传统的高压燃料泵中，由于环境因素，柱塞和保持器之间的过盈配合部分随时间而松动，并且这比必要性减小了保持器和挺杆之间的间隙，导致接触面压力增加 当侧向力作用在柱塞上时，在柱塞和气缸之间，这引起柱塞和气缸之间的卡塞。 在本发明中，在贯通孔周围设置有朝向挺杆突出的突出部，用于压入柱塞，设置在保持器的中心部分的通孔。 由于保持器和柱塞之间的间隙即使保持器和柱塞之间的接头松动也能够保持保持器和挺杆之间的间隙，所以即使侧向力也不会发生柱塞与气缸之间的咬合以及柱塞的破损 作用在保持架上。

    摘要： A temperature compensated level detector is disclosed in which a voltage multiplying rectifier is provided for rectifying and smoothing a high-frequency input voltage to obtain a DC output, and a bias voltage generator is added to said voltage multiplying rectifier, for providing a forward bias voltage. The bias voltage generator has a temperature compensating function.
