Title: Detecting device for obstacle point on light transmission passage, light node device, and light network device
Inventor: SAKAUCHI MASAHIRO
IPC: H04B10/275
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution by constituting this detecting device so that a laser gain medium generating Q switch pulse sent out to a light transmission passage and a light amplification gain medium amplifying return light pulse are shared by one active fiber. SOLUTION: The devices are arranged on the respective nodes of a ring type light network. Q switch pulses are output from both ends of an active fiber 4 and sent out to transmission passages L12, R15. When inverted population is sufficiently formed in the active fiber 4, by applying a RF signal on an AOM (acousto-optical modulator), the Q switch pulse is generated by a resonator setting the end face of the active fiber 4 and a mirror 12 as reflecting ends. When a failure occurs in the transmission passage L13 and light pulse returned from the obstacle point arrives at the node, the return light pulse is admitted to the active fiber 4 and amplified, and then it is converted to an electric signal by a light detector 8.  The electric signal is input to an electric signal pulse information processing circuit 9, arrival of the return light pulse is detected, and the occurrence of the failure point is detected.

Title: Method for separating out sprue parts from cast product
Inventor: SATO HIDEO
IPC: B22D31/00
Filed: 1992-12-31
Abstract: PURPOSE:To separate out sprue parts from a cast product by resonating a whole cast product in a high temp. range indicating the strength having about a half of the strength at a room temp. CONSTITUTION:A spheroidal graphite cast iron product 1 is in a molding sand, and when the temp. thereof is the lower transition temp., i.e., about 500-600 deg.C, the sprue part 2 is held therebetween by chuck mechanism 7 and the vibration having about 120Hz frequency is imparted to the cast product 1-4. Gates of the sprue parts preformed to the smallest cross section are used as joints and the gates are easily broken by the resonance, and the sprue parts and the cast product part can be separated with a small exciting device. By selecting the temp. range showing about <=1/2 of the tensile strength at the room temp. in the intermediate range between an upper transition temp. where the tensile strength starts to suddenly increase after the molten metal passes through the solidified point from the high temp. range and the lower transition temp. where the changing degree of the strength suddenly starts to slow down after the temp. further lowers, the cast product is given to the resonant condition.

A chemically synthesized product such as a compound of the formula (one of R<1> and R<2> is hydrogen and the other is acetyl) can also be used. The content of the tea saponin in the objective medicine may be selected, for example, from a range of 5-100 wt.%. The preparation may be administered, for example, at a daily dose of 5-200 mg/kg for an adult as the tea saponin with one to five portions. When directly sprayed in a nose or throat, 0.01-1 mg/ml of the solution may be sprayed several times.

Abstract: PROBLEM TO BE SOLVED: To improve the tracking performance of the energy control device of an excimer laser with respect to alterations of the objective value of pulse energy in a pulse oscillation in a burst operation mode and to control each pulse energy to be constant. SOLUTION: An energy control device is constituted in such a structure, that when pulse oscillation takes place in a burst operation mode, continuous pulse oscillations and continuous pulse oscillation interrupt during a prescribed time are repeated alternately, a learning control is executed in the initial stage of each continuous pulse oscillation.  After the learning control, the control of each pulse is executed and at the learning control, the current voltage command voltage Vi is calculated, on the basis of the result of the first pulse oscillation at the time of the last continuous pulse oscillation at the first pulse oscillation from the start of the oscillation and at the time of the control of above each pulse, the current voltage command value VI is calculated on the basis of the result of the oscillation immediately prior to the same time's continuous pulse oscillation to provide an output control part 10, to make the pulse oscillations take place and each pulse energy is controlled.  In this case, the control part 10 corrects the voltage command values Vi and VI corresponding to the amount of the change in the objective value Ed of each pulse energy at the time of the learning control and at the control of each pulse. For example, a voltage correction value ΔV for responding to a difference between both voltage command values, which respectively correspond to the current objective value Ed and a reference value, is added to the voltage command values Vi and VI for correcting the command values Vi and VI.
