摘要： An insulated gate bipolar transistor having a reverse conduction function and comprising a semiconductor layer of a first conductivity type on the drain side, a semiconductor layer of a second conductivity type formed thereon to develop conduction modulation upon injection of carriers, a semiconductor layer of the second conductivity type that is formed in the above semiconductor layer of the second conductivity type and electrically connected to the drain electrode to take out the reverse conduction current flowing in a direction opposite to the drain current, and a semiconductor layer of the second conductivity type that is formed in the boundary surface or near the boundary surface of pn junction where the carriers are transferred to effect conduction modulation, and that has a high impurity concentration so as to serve as a path of the reverse conduction current and has a pattern which does not impair the transfer of the carriers. Owing to the above construction, there is incorporated a reverse conduction function having a small operation resistance, and it is allowed to flow a large current in the reverse direction, preventing the on-resistance from increasing and shortening the turn-off time.

摘要： An antiskid controller capable of executing precise ABS control by correctly estimating a road surface mu without using an additional sensor. The speed of each wheel is detected, and acceleration of the car body is determined when the difference in speed between the front and rear wheels exceeds a predetermined value. This acceleration is defined by the rate of the change with time of the wheel that has a smaller change in speed, and the road surface mu corresponding to this acceleration is determined. Transverse G is obtained from the difference in speed between the right and left wheels, and corrections for turning, driving on a hazardous road, a change in mu etc., may be executed.

摘要： A rotary phase of a camshaft in an internal combustion engine is regulated by varying a rotational position of a vane rotor in a shoe housing. Each of two vanes of the vane rotor is provided therein with a set of a check valve and a pilot valve as moving members adapted to be moved in parallel with a rotary shaft, by which valves the opening and closing of oil passages are controlled. Since the moving members are moved in parallel with the rotary shaft, the movements thereof are not prevented by a centrifugal force occurring due to the rotation of the rotary shaft. The moving members are housed in the vanes and enlarge the vanes so that the dimensions, especially the outer diameter of the rotor does not increase. Moreover, the sealability of an advancing side hydraulic chamber and a lagging side hydraulic chamber positioned on both sides of each vane can be secured.

摘要： A device for subjecting a current flowing through an exciting coil of an alternate current generator for an automobile to exciting and/or deexciting control through a digital circuit. A voltage pulse having a width corresponding to a phase difference between counts of first and second counters (15, 16) which perform counting at predetermined clocks is outputted from a maximum conducting duty limiting circuit (19). In a case where the output voltage of the generator is greater than a reference voltage, the phase difference is reduced by shortening the full-scale counting time of the second counter relative to that of the first counter, while in a case where it is smaller than the reference voltage, on the contrary, the full-scale counting time of the second counter is lengthened relative to that of the first counter, thereby extending the phase difference. Current flowing through the exciting coil of the generator is controlled by a switching transistor (12) in accordance with the above voltage pulse.

摘要： A soldering method wherein, even when, for example, a pressure sensor unit having a sensor chip incorporating therein a highly integrated type semiconductor circuit is jointed to a metal stem, fluxless soldering can be performed without damaging the surface of the sensor chip. For this purpose, in forming a nickel layer for jointing by soldering and an oxidation preventing layer of a nickel layer on the surface of a member to be jointed, this oxidation preventing layer is formed before the soldering to a film thickness for suppressing exposure of nickel of the above-described nickel layer to the outermost surface of the member to be jointed after a thermal histeresis in association with the thermal histeresis to be received by the member to be jointed, the oxidation preventing layer is heated in a reducing atmosphere to melt a soldering foil and jointed to another member to be jointed by soldering. With this arrangement, even if the member to be jointed is subjected to the thermal histeresis before the soldering, exposure of the nickel layer, which is a base ground, to the outermost surface of the member to be jointed can be effectively suppressed, whereby substantially, there is no lowered soldering wettability on the jointed surface of the member to be jointed, even if the load imposed on the jointed portion is not increased during the jointing by soldering, satisfactory soldering wettability on the jointed surface can be realized, and, since the jointing by soldering is effected by heating in a reducing atmosphere, a fluxless soldering is possible that can provide highly tightly sealed jointed portion. Therefore, in jointing the pressure sensor unit having the sensor chip incorporating therein the highly integrated type semiconductor circuit to the metal stem, there is no need of loading the metal stem with the sensor chip facing downward, so that a disadvantage of damaging the surface of the sensor chip can be obviated.
摘要翻译：一种焊接方法，其中，即使例如具有结合有高度集成型半导体电路的传感器芯片的压力传感器单元连接到金属杆上，也可以在不损坏传感器芯片的表面的情况下进行无焊接焊接。为此，在通过焊接形成用于焊接的镍层和镍层的防氧化层的待接合构件的表面上，将该氧化防止层在焊接前形成为用于抑制镍暴露的膜厚度的上述镍层与待接合部件接受的热分升速度相关联的热等离子体收缩后的被接合部件的最外表面，在还原气氛中加热氧化防止层，使其熔融焊接箔并与另一个通过焊接接合的部件接合。通过这种布置，即使在焊接之前要接合的构件进行热分解，也可以有效地抑制作为基础接地的镍层的暴露于待接合构件的最外表面，从而基本上即使在焊接接合时施加在接合部上的负荷没有增加，也可以在接合部件的接合面上降低焊接润湿性，能够实现接合面上的令人满意的焊接润湿性，通过在还原气氛中加热来实现焊接的接合，能够提供高度密封的接合部的无焊剂焊接。因此，在将具有内置有高度集成型半导体电路的传感器芯片的压力传感器单元接合到金属杆上时，不需要将传感器芯片朝下的金属杆加载，从而不利于损坏表面可以消除传感器芯片。

摘要： The present invention relates to a solenoid valve useful for brake hydraulic control of hydraulic equipment, in which pressure intensifying control is effected, in particular, automatic braking systems for vehicles. The solenoid valve of the present invention comprises a moving member (7) adapted to be moved by an electromagnetic force, a spherical-shaped communication cutoff member (13) biased by the moving member (7) and a seat member (11) having a tapered surface. The communication cutoff member (13) and the moving member (7) are disposed in the same space such that when fluid flows out from the space to another space, a negative pressure is produced only between the communication cutoff member (13) and the seat member (11), which negative pressures sucks the communication cutoff member (13) toward the seat member (11). With this arrangement, when a force acting in a direction, in which the valve closes, is positively used, pressure intensifying can be effected in a pulsing manner with the valve experiencing not a full stroke but a minute stroke in a range of differential pressure, that is, with the flow passage area of the valve kept small, so that good control is made possible without increasing a pressure intensifying amount.

摘要： The title device has a simple and inexpensive structure and can reliably execute a writing process only once even when receiving write signals repeatedly in communication between an antenna unit and a response unit provided in the mobile object. Receiving a write signal from a write antenna unit, the tag unit (response unit) executes a process of writing the data in the data memory on condition that the completion flag is cleared by a control circuit. When the writing process is executed, the control circuit sets the completion flag. After this, even if write signals are repeatedly received in the same communication area of the same write antenna unit, the control circuit nullifies the writing proces because the completion flat is set, hence preventing multiple writing.
