Title: Echo canceller
Inventor: HONDA TADASHI
IPC: H04B3/23
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To obtain an echo canceller by which speech quality is improved by suppressing an echo generated depending on the length of subscriber lines for a 2-wire block. SOLUTION: An LPF 11 extracts components of a transmission signal below 500Hz outputted from. a CODEC 6, and a level detector 12 detects whether or not the level of the components is higher than a preset threshold level. When the detected level denotes a higher level, the detector 12 provides an output of an ON signal to close an ON/OFF switch 13, an inverted signal by an inverter circuit 14 opens an ON/OFF switch 15 so as to give the transmission signal to a phase correction device 16 and the phase of the component with a frequency band of 500Hz or below is corrected and the result is given to a subtractor 5. When the detection level is low, the switch 13 is open and the switch 15 is closed to provide the transmission signal to the subtractor 5 without any modification.  Then an echo canceller 4 provides an output of a suppression signal where the phase of the low frequency component is corrected corresponding to the length of a subscriber line 9 connecting to the echo canceller 4.

Title: Foil wound transformer
Inventor: INUI AKIFUMI
IPC: H01F27/20
Filed: 1987-06-16
Abstract: PURPOSE:To improve dielectric strength by supporting part of a winding by an insulator, such as a pressboard, and supporting the part the winding by disposing a post type spacer. CONSTITUTION:A low voltage winding 4 is supported by stacking one or more blocklike insulators 21, such as pressboards in an insulated state to grounded element, such as a core clamp or a shield 10 clamped to the core clamp from below or from both above and below. On the other hand, a high voltage winding 5 is supported by post type spacers 22 disposed at several positions circumferentially from below or from both below and above. The spacer 22 is manufactured by pouring an epoxy material in a metal mold. Thus, its structure is more simplified to improve its operability and economy. Further, since a high electric field section is supported by a spacer having high dielectric breakdown strength and in a manner distributed circumferentially of the winding, its insulator reliability is improved.

A slab of this steel is heated to >=1050 deg.C and formed into a plate by hot rolling finishing at 850-950 deg.C. This plate is cooled rapidly from a temp. not lower than the Ar3 point down to 400-550 deg.C at (3 to 20) deg.C/sec cooling rate, further reheated to a temp. in the region between the Ac1 and the Ac3 point, and cooled rapidly. If necessary, tempering is done at a temp. lower than the Ac1 point. By this method, the refractory steel plate for architectural use, having a composition in which the fraction of secondary phase other than ferrite is regulated to >=20% and excellent in earthquake resistance, can be obtained.

Title: Electromagnetic wave suppression device
Inventor: MASUDA HISAHIRO
IPC: H05K9/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To avoid effect on a protection target by forming the space room between first and second surfaces, filling a liquid or a member being impregnated with the liquid into the inside, and including it between an object for generating electromagnetic waves and, for example, a human body. SOLUTION: When, for example, a device covers an antenna 1 of a portable telephone for use, electronic waves emitted from the antenna 1 are discharged into space through an inner cylinder 3, (water of) a space room 5, and an outer cylinder 4. However, by ignoring the materials of the inner cylinder 3 and the outer cylinder 4 after the electronic waves are emitted from the antenna 1 into air once, it passes through the water in the space room 5, and then is sent to air. The electrical conductivity of water is lower than that of air and may be used as a conductive material, so that a wave impedance difference is generated at the boundary between air and water and the electronic waves can be suppressed due to the difference.  Therefore, by appropriately selecting the size of the space room 5 and the type of the liquid to be filled, the desired suppression effect of the electronic waves can be achieved.

Filed: 1981-09-18
Abstract: PURPOSE:To improve the dimensional accuracy of an underwater molded motor by molding the periphery of a coil end with unsaturated polyester resin and covering the outer periphery of a stator core with metal and unsaturated polyester resin, thereby eliminating a damage to the coil. CONSTITUTION:The outer periphery and the side of a stator core 2, to which a thin stainless steel can 3 is inserted into the inner periphery and the periphery of a stator coil end 5 are molded with resin molding member 4 made of unsaturated polyester resin, and the outer periphery of the member 4 is covered with an inner layer sheath 61 made of metal and a metal sheath 62 made of unsaturated polyester resin. In this manner, since the resin can be molded at low pressure and temperature, a damage of a coil can be eliminated, and the dimensional accuracy can be improved due to low shrinkability. Further, the sheath 61 can be prevented from corroding via the sheath 62.

Title: Preventing method of internal cracking in continuous casting
Inventor: IMAI FUMIO
IPC: B22D11/16
Filed: 1978-11-30
Abstract: PURPOSE: To rapidly perform internal cracking preventing measures by estimating the internal cracking of the slab being made based on dynamic roll gaps and operating conditions during continuous casting and obtaining a cause roll from the result of this estimation.  
     CONSTITUTION: A roll gap continuously changes owing to the changes in thermal load, mechanical load or the rolls per se during continuous casting. Also, the solidified shell condition of the slab changes relatively with the changes in operating conditions. As a result of this, the stress exceeding the yield strength to cracking acts in the shell, thereby producing an internal cracking quality defect in the slab. For this, the following processings are performed. Namely, the dynamic roll gap during casting is measured and solidified shell thickness is calculated from the rates of slab cooling, casting temperatures, molten steel temperatures, steel kind com- ponents, etc. Next, from these factor groups, internal breakage estimation is on-line- performed and based on this, a cause roll is obtained. Further based on this result, internal cracking preventive measures such as casting speed decrease are on-line-fed back rapidly in an optimum manner.
