摘要:
There are provided a first mold 2 and a second mold 1 that can be brought into and released from contact with the first mold 2. A substrate 70 provided in both the molds 1, 2 and mounted with electronic components is subjected to resin sealing and molding by filling with resin of cavities formed by both the molds 1, 2. The second mold 1 is placed on a base plate 9 so as to be capable of horizontally reciprocating, and has a cavity block 7 that can be brought into and released from contact with the first mold 2 and a mold clamping mechanism 16 that supports the cavity block 7 and that brings and releases the cavity block 7 into and from contact with the first mold 2 so as to perform mold clamping. On the base plate 9 is provided a horizontal actuation mechanism 11 for moving the second mold 1 to a facing position where the second mold 1 faces the first mold 2 and to a non-facing position where the second mold 1 has been moved sideways from the facing position.

摘要:
In a surge protection circuit in a three-phase four-wire circuit, a first three-phase three-wire surge module includes terminals respectively coupled to a first phase R, a second phase S, a third phase T, and a fifth phase E. A single-phase two-wire surge module includes terminals respectively coupled to one phase R among the first phase R, the second phase S, and the third phase T, to a fourth phase N, and to the fifth phase E. The second three-phase three-wire surge module includes terminals respectively coupled to the two phases S and T among the first phase R, the second phase S, and the third phase T, to the fourth phase N, and to the fifth phase E. The two phases S and T are not coupled to the single-phase two-wire surge module.

摘要:
A resin sealing mold for semiconductor devices, which is designed to thoroughly accommodate board thickness variations and prevent formation of burrs and which is easy to maintain. To this end, a plurality of pistons (42) supporting, at one of their respective ends, lower mold cavities (56) have the other ends thereof slidably inserted in hydraulic cylinder blocks installed on lower mold sets (40).

A gas engine system has a control unit including: a first determination section for determining, as a first determination, whether the gas pressure is a low pressure less than a predetermined pressure, while the control device recognizes the gas valve is closed; a second determination section for determining, as a second determination, whether the gas pressure is a high pressure equal to or more than the predetermined pressure, while the control device recognizes that the gas valve is open, if the first determination determines the gas pressure is the low pressure; a start-up section for performing the first and second determinations before start of engine operation when receiving a start-up command; and an operation start section for opening the valve and starting the engine, if the first determination determines the gas pressure is the low pressure, and if the second determination determines the pressure is the high pressure.
摘要:
A resin molten in a pot portion 59 is molded by being loaded via a gate 48 into a cavity, which has a rectangular parallelepiped shape in plan view and is formed of both molds 1 and 2, which are a second mold 2 and a first mold 1 that can make or release contact with the second mold 2. The pot portion 59 is provided at either one of the molds 1 and 2 and constituted of recess portions 54c located at prescribed intervals at the cavity. The recess portions 54c have a bottom surface constituted of part of a moving member 60 movable toward an opening portion. The gate 48 is structured so that one side of the cavity and the long side of the pot portion 59 are connected with each other.
摘要:
An optical transmission/reception module including a filter holder on which filter mount surfaces for mounting wavelength division multiplexing filters and light wavelength band limiting filters are formed and in which a hole for guiding a light signal is formed in each of the filter mount surfaces incorporated into a housing. The wavelength division multiplexing filters and the light wavelength band limiting filters are mounted to the filter mount surfaces formed on the filter holder, respectively.

摘要:
A collision detection system utilizing a set of primary sensors and a secondary sensor. When a sufficient collision load is applied to the sensors, the sensors output a signal. The primary sensors are constructed to be more sensitive than the secondary sensor. Based on the outputs of the primary and secondary sensors, a control unit detects the collision. Upon detecting the collision, the control unit outputs a collision detection signal which activates a protection device, such as an air bag.
