Title: Multistage optical amplifying device
Inventor: TAKARA HIDEHIKO
IPC: H01S3/06
Filed: 1991-06-27
Abstract: PURPOSE:To improve the gain and S/N by driving an optical switch arranged on the output side of each optical amplifier synchronously with a signal light pulse to remove natural emission light from the output light of the optical amplifier on the time base synchronously with the signal pulse. CONSTITUTION:When a signal light pulse 35 is made incident on an optical amplifier 13 in the first stage, output light 36 where natual emission light is superposed on the amplified signal light pulse 35 is outputted from the optical amplifier 13 and is made incident on an optical switch 31 in the first stage. A current (or voltage) signal 37 synchronized with the signal light pulse 35 is applied to the optical switch 31 from a driving device 33. The optical switch 31 allows the light to pass through only in the period of existence of the signal in the signal 37 but intercepts the light in the other period. Consequently, signal light 38 where almost all of the natural emission light in the period of the absence of the signal light pulse 35 is removed is outputted from the optical switch 31. With respect to output light of optical amplifiers 14 in second and following stages, the level of natural emission light is reduced by time gating due to optical switches 32 in the same manner.

Abstract: PURPOSE: To suitably flatten the surface of a silicon substrate without polishing the surface of an element forming region by mechanochemical polishing methods. CONSTITUTION: An oxide film 2 is formed on the surface of a silicon substrate 1, and after formation of a thick element isolation oxide film 4 utilizing a nitride film 3 which is selectively formed, an insulating film (second nitride film) 5 is formed on the whole surface, and a polishing operation is conducted using a mechanochemical polishing method in such a manner that the nitride film 3 is left on an element forming region. Then, the left nitride film 3 is removed, and the surface is flattened by etching the oxide film 2 and the element isolation oxide film 4.  The above-mentioned mechanochemical polishing is conducted in the range of the total film thickness of the nitride film 3 and the insulating film 5, the polishing of the surface of the element formation region can be prevented by having a sufficient range of margin of thickness control, and the deterioration of element characteristics can also be prevented.

Title: Controlling method of air conditioner
Inventor: ISAJI AKIRA
IPC: F24F11/76
Filed: 1982-09-09
Abstract: PURPOSE:To perform a pleasant heating operation by a method wherein the temperature of an indoor heat exchanger drops suddenly immediately after the stoppage of a compressor during a heating operation, the output signal of a thermosensor which can not follow the temperature drop is corrected by a microcomputer to thereby control a fan motor. CONSTITUTION:The increase of the temperature of an indoor heat exchanger is slow at a time immediately after a compressor 1 is started. Therefore, a thermosensor 7 follows it well and the microcomputer 5 controls the number of revolutions of an indoor fan motor 8 without correcting the output signal of the thermosensor 7. However, when the compressor 1 is stopped, the temperature of the heat exchanger 11 drops suddenly to reach the room temperature but since the thermosensor 7 can not follow the temperature drop sufficiently, the microcomputer 5 reduces the number of revolutions of a fan motor 8 in response to the output signal of the thermosensor 7. Consequently, it is possible to utilize the heat of the open air effectively for performing a pleasant heating operation.

Filed: 1978-12-19
Abstract: PURPOSE:To enhance efficiency in semiconductor assembly by a method wherein a metal plate which holds lead wires is sent on conveyor while being assembled, then its direction is turned, and the other side undergoes assembly work on downstream conveyor. CONSTITUTION:A metal plate 2 which holds lead wires 1 is placed on conveyor 11 and undergoes assembly work at one side, then enters the resess 12 of rotary member 9 engaged with rotary base 10, where the plate 2 stops. The detector 14 at the entrance of the base 10 recognizes the plate has passed, and causes the rotary member 9 to turn 180 deg.. This transfers the metal plate 2 to the conveyor 11 downstream to enable the plate 2 to be assembled on the lead wires at the other side. The process allows assembly to be performed only one side, thereby to facilitate assembly layout and to enhance work efficiency.

Filed: 1977-12-28
Abstract: PURPOSE: To provide a stretcher which can curtail equipment cost with a reduced installation space with a wire stretching oil purifier mainly comprising a wire stretching oil and air blowing means incorporated under the wet wire stretcher.  
     CONSTITUTION: When wire stretching starts with the rotation of a capstan 11 driven by a drive shaft 16, an agitation fan 22 rotates through a transmission mechanism 21. Consequently, air from an air intake guide 23 is released into a wire stretching oil 14 in the form of a bubble 26. With this bubble as a medium, impurities including fine metal particle in the oil are coagulated and as the coagulated body grows large, the bubble 26 is broken and settles on the bottom of a wire stretching oil tank. In this manner, purification of the stretching oil is possible with a simple construction, minimizing the installation space. Thus, equipment and construction costs can be saved.

Title: Full automatic control bath heater
Inventor: KIKUCHI TORU
IPC: F24H1/00
Filed: 1989-06-19
Abstract: PURPOSE:To prevent the generation of chattering phenomena by halting the operation to drop water into a bath furnace main body under the assumption that a control section should allow a water level detection sensor to detect a predetermined water level continuously for a specified time. CONSTITUTION:Even when a hot bath water level has not reaches a preset water level, the zigzag-like fluctuation induced by water filling motion into a bath tub may indicate momentarily that the water has reached a specified water level. However, a water level detection sensor 8 is designed to output no power even when it detected momentarily that the water has filled the batch tube to a specified level unless this detection continues, say, at least five seconds so that the water filling motion may continue as it remain. When the five seconds have elapsed, the actual hot bath water level has exceeded the preset water level and the output power is transmitted to a control section 11 after the lapse of five seconds so that a water filling valve 10 may be closed to halt the water filling operation. Therefore, it is possible to eliminate 'chattering phenomena' definitely or repeated on/off operations of the water filling vale 10 induced by the water level detection sensor when the bath water level approaches the preset water level.
