Patent JP-H11150425-A (JP)
Title: Light reception circuit
Inventor: YAMADA TETSUYA
IPC: H04B10/50
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent an avalanche photo diode from breaking down by generating noise corresponding to the output of a full AGC circuit, namely, noise which corresponds to the bias voltage of the avalanche photodiode, superimposing it on a signal and suppressing th over-rise in the output of the full AGC circuit, even if optical input power becomes minute. SOLUTION: When optical input power inputted to the avalanche photodiode 1 becomes minute, the output of a level detection circuit 3 is reduced and the output voltage of the full AGC circuit 4 rises. The output voltage is supplied to a diode 6 via resistors 8a and 8b, an operational amplifier 7 and a resistor 8c. Thus when the optical input power becomes minute, the bias current of the diode 6 increases, and average noise power which the diode 6 generates becomes large. The noise is superimposed on the signal and is supplied to the level detection circuit 3. Thus, the output of the full AGC circuit 4 is prevented from rising excessively even if optical input power becomes mounts.

Title: Delay relay
Inventor: OTA OSAMU
IPC: H01H50/86
Filed: 1990-11-20
Abstract: PURPOSE:To set the delay time to any desired value by making segregation and attachment magnetical so as to open and close a magnetic circuit in delay while a migrative delay is given to an electroconductive magnetic substance either in energized or deenergized state through the action of the viscosity of a fluid, and thereby opening and closing relay electrode from/to each other. CONSTITUTION:An insulative fluid 7 and electroconductive magnetic substance 6 are airtightly encapsulated in a vessel 1a in which electrode is provided on the inside of each end, and thus a relay part 1 is provided, which is inserted in a magnetic circuit composed of a permanent magnetic pole 5 and a yoke 2 penetrating an energization coil 3, and energization is made by feeding current to this coil 3. Therefore, the electroconductive magnetic substance 6 makes delayed migration in the insulative fluid 7 to attach magnetically between the electrodes to generate shortcircuit relaying, or a stop of current feed allows it to again make magnetic attachment to the permanent magnetic pole while being delayed to result in tripping. That is, the migration is made relatively slowly immediately after energization because of viscous resistance of the insulative fluid 7. Thereby the delay time can be set to any desired value by previously determining the shape and dimensions of the electroconductive magnetic substance 6, viscosity of the insulative fluid, size of energization, etc.

Abstract: PURPOSE:To enhance a breakdown voltage value of a trench capacitor by a method wherein a reactive ion etching operation is executed by using a fluorine-based etchant and a phospho-silicate glass layer is removed in order to eliminate an acute bend to be produced at an edge part of an entrance of a trench. CONSTITUTION:After a PSG layer 4 has been formed on an Si substrate 1 by a CVD method, an opening 5 is formed in the PSG layer 4 by a photolithographic method. Then, after this Si substrate 1 has been set in an RIE apparatus, BCl3 and Cl2 as etchants are supplied to the inside of the apparatus; an RIE operation is executed by using high-frequency electric power while a vacuum degree is kept in a stationary state after evacuation; a trench 2 is formed. Then, the gases inside the apparatus are replaced by BCl3 and SiCl4; the RIE operation is executed while the vacuum degree is kept in the stationary state; a sawtooth-like defect or the like inside the trench 2 is removed. Then, a mixed gas composed of CF4 and CHF3 is supplied to the inside of the apparatus; the gases are replaced; the apparatus is evacuated; while a prescribed vacuum degree is kept, the RIE operation is executed by using the high-frequency electric power; the PSG layer 4 on the Si substrate 1 is removed. By this process, a round taper is formed at an edge part 3 of an entrance of the trench 2.
