Abstract: PURPOSE:To improve the workability and accuracy of angle detection and to simplify a titled device by combining a stationary plate which moves together with a boom, and a light emitting device and a photodetector which stay still in a constant position in spite of the depression or elevation of the boom. CONSTITUTION:While a rocket 5 and a boom 3 are in a vertical state, a light emitting device 14 and a photodetector 15 are opposite to the point (a) of a light transmission part 12, and the light transmitting through the part 12a is detected with the photodetector 15, wherby it is detected that these are in the vertical position. When the rocket 5 and the boom 3 are depressed or elevated to an angle theta of elevation, an arc-shaped stationary plate 12 displaces relatively by an angle alpha, that is, the angle of elevation. On the other hand, a static member 11 does not move in spite of the depression or elevation of the boom 3 and therefore the light emitting device 14 and the photodetector 15 moves from the point (a) to (b). The number of the parts 12a from the point (a) to (b) are detected and is converted to an angle which is displayed. Thereby, the workability and accuracy of the angle detection are improved and the device is simplified.

Title: Pcm voice data multiplexer
Inventor: IMAEDA YOSHITERU
IPC: H04J3/17
Filed: 1992-02-04
Abstract: PURPOSE:To improve the data multiplexing efficiency of the multiplexer by inserting data into the section of a digital speech by utilizing a range bit which indicates that there is not information bit in a high speech section. CONSTITUTION:When a signal format including the range bit indicating that there is no information bit in a section of a specific number of bits counted from the MSB(Most Significant Bit) included in digital speech information is outputted from an A/D converter 1A, a range bit detector 4 detects this range bit and informs a data controller 6 of information on the absence of specific bits from the MSB. The data controller 6 when receiving the absence information sends packet data, etc., previously stored in a memory 5 to a multiplexer 3. The multiplexer 3 adds the packet data, etc., right behind the MSB and multiplexes the data. Thus, a free time slot in the digital speech in ch is utilized, so the multiplexing efficiency of the digital speech and digital data can be increased.

Abstract: PURPOSE:To accomplish high-speed driving by disposing a winding portion of a force motor, a pilot spool and a support spring which have the same diameter on the same shaft in such a manner as to be brought into pressure contact one another, the pilot spool being a thin hollow cylinder. CONSTITUTION:A pilot spool 42 comprising a coil winding 40 and a thin hollow cylinder is supported on a concentric circle by cylindrical springs 41, 43, one spring 41 being disposed on the magnet side, the other spring 43 being disposed on the left end of a body 60 in such a manner that all parts connected to one shaft are fixed by pressure. Since the spool 42, the coil winding 40 and the springs 41, 43 are diposed on one shaft, power transmitssion can be natural, and there is no member to lower rigidity, which results in that a spool valve itself can be fit for high-speed drive. Furthermore, since the actuator is interposed in the the spool 42, a transmission lag caused by the length of an oil path between the spool 42 and the actuator is reduced so as to accomplish high-speed driving.

Abstract: PURPOSE:To obtain a plasma control apparatus, which is suitable for stabilizing plasma when discharging is started by starting the plasma discharging with a low one-round voltage in nuclear fusion apparatus. CONSTITUTION:A poloidal magnetic field is adjusted and the shape of the position of plasma is controlled in a plasma control apparatus of a nuclear fusion apparatus. In this plasma control apparatus, a plasma control system, which can add the magnetic field of a current transformer and can independently add a quadruplex-pole magnetic field, is formed. The plasma control system is constituted of a quadruplex-pole- magnetic-field-strength command device 10, a null-point-position command device 9 for determining the position of the null point and an operation detector 4 for the null point and the strength of the quadruplex-pole magnetic field. The quadruplex-pole magnetic field is applied before the plasma generation when the plasma discharging is started. The null point, where the poloidal magnetic field is not present, is generated and maintained. The position of the null point is measured and negatively fed back, and the position is controlled. Since a nuclear fusion apparatus can be started with a low one-round voltage, the stabilization and the reproducibility of the plasma at the start of the discharging are improved, and the cost reduction of the apparatus is possible.
