Patent JP-H01136384-A (JP)
Title: Driving circuit for semiconductor laser
Inventor: HORI AKIHIRO
IPC: H04B10/00
Filed: 1987-11-24
Abstract: PURPOSE:To form a semiconductor-laser driving circuit capable of high-frequency overlapping operating at high speed by a simple circuit by inputting a transmission signal to one gate for a dual gate field-effect transistor, inputting overlapping frequency to the other gate and connecting a semiconductor laser to the source or drain side. CONSTITUTION:A transmission signal is input to a first gate 4 for a dual gate FET 1. High frequency from a high-frequency oscillator 6 is input to a second gate 5 for the FET 1. Consequently, currents flowing through a semiconductor laser 2 through a resistor 3 are brought to a state in which high-frequency modulation is applied to a transmission signal input. When a GeAsFET is used as the dual gate FET 1, operation at high speed is enabled.

Inventor: MITSUNARI TAKASHI
IPC: E02D27/34
Filed: 1988-11-21
Abstract: PURPOSE:To decrease consolidation reduction and cope with the liquefaction of a sand layer by providing water storage tanks and water stop walls around structures, forming gravel drains, and raising or lowering the ground water level than the ordinary water surface. CONSTITUTION:Large water storage tanks 3 and 13 are provided around structures 2 and 12, and water stop walls 5 and 15 reaching clay layers 4 and 14 are separately formed on the whole periphery. Gravel drains 8 and 18 packed with crushed stones or the like are formed below structure batholithes 6 and 16 and between outer peripheries 7 and 17 and the water stop walls 5 and 15. When the structure 2 is a medium scale and the consolidation settlement is large, water is fed in the gravel drain 8 from the water storage tank 3, the ground water level 10 is raised from the ordinary water surface 9, and the consolidation settlement of the clay layer 4 continued below a sand layer 11 is decreased. When the structure is a small scale, the structure batholith 16 is further dug to form a deep well 19, underground water is drawn up by an underwater pump 20, and the ground water level 22 is lowered than the ordinary water surface 23 to cope with the liquefaction of a sand layer 24.

Title: Coin detection mechanism for coin accumulation cylinder
Inventor: KAMATA HITOSHI
IPC: G07D9/00
Filed: 1988-11-21
Abstract: PURPOSE:To surely detect the presence and absence of a coin in a coin accumulation cylinder and the generation of a jamming by a sensor arranged on a straight line to link a through hole for an upper edge position when the supporting plate in the coin accumulation cylinder is at the upper edge and a through hole for a lower edge position when it is at the lower edge. CONSTITUTION:When a supporting plate 54a in a temporary pooling cylinder 53 is at a lower edge position, the optical axis of photo sensors 59 and 60 transmits a through hole 54p for a lower edge position of the plate 54a, and thus, it is detected that the coin is not in the cylinder 53 and the inputting preparation completion of the coin is detected. Next, when the coin is inputted, the optical axis is interrupted by the coin. When the plate 54a rises and arrives at the upper edge position, all coins are fed, the optical axis transmits a through hole 54n for an upper edge position and detected by the sensors 59 and 60. When the abnormal condition occurs, since the plate 54a does not arrive at the upper edge position, the light axis is interrupted by the plate 54a and can be detected. Consequently, the presence and absence of the coin and the generation of the jamming can be surely detected.

Abstract: PURPOSE:To enable safe and efficient hole opening operation by controlling the letting out speed of a consumable oxygen lance and the position of the lance with respect to a tap hole in the stage of straightening and letting out the lance and opening the tap hole. CONSTITUTION:The consumable oxygen lance 12 wound on a take-up drum 14 is straightened by a straightening and letting out device 15 and is let out to the tap hole 17. The tap hole is opened while oxygen is fed thereto. a swiveling arm 21 lifts a lance letting out device 13 freely turnably by means of a lifting rod 22 and is freely turnably driven by an air motor 25. The swiveling arm 21 is made freely turnable by a clutch mechanism 26 with a resetter when the swiveling arm 21 turns from the standby position to a position ready for hole opening. The force from a pressing force applying device 27 is exerted to the arm 21 through a tension wire 28 so that the arm is directed at all times toward the tap hole 17. The swiveling arm 21 turns toward the tap hole 17 when the melting speed increases so as to exceed the letting out speed of the lance 12. The rate of the air to be supplied to the air motor for driving the letting out roller is then changed to decrease the letting out speed of the lance 12.
