Title: Squelch circuit of fm-am receiver
Inventor: OKADA HISAO
IPC: H04B1/10
Filed: 1979-08-10
Abstract: PURPOSE:To avoid the unnaturalness at scanning, by the squelch with the signal obtained from noise from the FM detection circuit in operation state at FM and AM reception with rectification. CONSTITUTION:At non-signal, at FM and AM reception, the noise appeared at the terminal 9, i.e., the output terminal of the FM detection circuit 14, is applied to the voice volume VR1 and active BPF21. The BPF21 detects noise outside the voice band, the noise is rectified at the diode D3 and applied to the input terminal of the squelch switching circuit 24. Since the AGC at AM side is not effective at non-signal, RFAMP and IFAMP are at maximum gain state, and since the noise voltage from the FM detection circuit 14 is equal at FM and AM reception, the operating point of squelch can be set to the same position at FM and AM reception.

Title: Signal transmission system
IPC: H04Q1/45
Filed: 1992-03-30
Abstract: PURPOSE:To allow a DC loop to be open only at a very low rate regardless of a false DTMF signal in the speaking voice by combining two kinds of DTMF signal to confirm the end of speech. CONSTITUTION:Just before the DTMF signal sent at the time of the end of speech, another short DTMF signal is sent to open the DC loop. Thus, the probability of erroneous opening of the DC loop is very reduced even if the false DTMF signal of an electronic music box or the like exists during speech.

Title: Lance pipe for blowing gas
Inventor: SOEDA TOMOMI
IPC: C21C7/072
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of crazing and cracking, etc., on refractories and to prolong durable service life by arranging plural bar steels in parallel to a core metal of a lance pipe for blowing gas, weld-joining both ends of each bar steel to the core metals and applying the refractories on the outer periphery thereof. SOLUTION: Plural bar steels 2 are arranged in parallel to the core metal 1 of the lance pipe for blowing the gas, and both ends of each bar steel 2 is weld-joined 3 to the core metal 1 respectively. This core 1 is set to a metallic mold for forming the lance pipe for blowing the gas and the refractory 5 is cast on the outer peripheral part and formed, separated from the metallic mold and dried to make the lance pipe for blowing the gas.  In such a way, the intermediate part of the bar steel 2 is not fixed but becomes flexible by forming the core metal structure welding only both ends of the bar steel 2 arranged in parallel to the core metal 1, then since the bar steel does not directly follow to expansion of the core metal 1 but has the elasticity, the crazing and the cracking are not caused on the refractories 5 at the outer peripheral part and the lance pipe for blowing the gas capable of stable operation is obtd.

Title: Copper metallization onto ceramics
Inventor: KAJITA SUSUMU
IPC: C04B41/88
Filed: 1987-04-24
Abstract: PURPOSE:To prevent the metallized copper from deterioration of adhesion to the ceramic caused by heat treatment at elevated temperature, by converting metallized copper on an oxide surface of a ceramic into its sulfide and bonding copper to the sulfide and heat-treating them in a specific atmosphere at specific temperature. CONSTITUTION:A ceramic is metallized with copper on its surface by the wet or dry method. The metallized copper is sulfidized into copper sulfide. Further, the sulfidized copper is metallized with copper by the dry or wet method, but direct electrolytic metallization cannot be done, because the primer is copper sulfide. Then, the copper-metallized ceramic base is heat-treated in an inert gas of 5-100ppm O2 content at temperature from 600 deg.C to the melting point of copper. Thus, a compound of Cu-O-ceramic is formed and resists marked reduction of adhesion on later heat treatment at elevated temperature.

Title: Phase control device
Inventor: ANO MITSUYOSHI
IPC: H02P27/02
Filed: 1979-08-15
Abstract: PURPOSE:To simplify the configuration of the phase control device by providing only one phase control circuit and commonly using it by switching it for low and high speed triacs. CONSTITUTION:When a speed setting unit VR is gradually raised at its setting voltage, the output of a Schmitt trigger circuit ST is inverted to turn a transistor Tr2 on to supply a gate signal from a firing phase circuit PH to the gates of a high speed  triacs TRI4-TRI6, thereby flowing a current through less windings to drive a motor PCM at high speed. At this time the low speed triacs TRI1-TRI3 are turned off. When the motor speed is decelerated lower than the synchronizing speed by  the unit VR, the Schmitt trigger circuit ST is inverted to turn off the high speed  triacs TRI4-TRI6, and the low speed triacs TRI1-TRI3 instead start controlling  the voltage.

Title: Steelmaking method using top-blown converter
Inventor: ISHIGURO MORIYUKI
IPC: C21C5/32
Filed: 1980-07-29
Abstract: PURPOSE:To contrive to enhance the yields of iron and Mn by a method wherein a refining gas consisting of a mixture of oxygen and an inert gas is blown downward through a top-blowing lance and, simultaneously, the lance is whirled during the refining process. CONSTITUTION:As the refining gas, a mixture of oxygen and an inert gas such as Ar and N2 is used. The mixed gas is blown downward through a single top-blowing lance and, simultaneously, the lance is whirled during the refining process. By this method, it is possible to increase the effective collision energy with which the top- blown gas impinges upon the molten pig, iron, stirring the slag and the molten steel more effectively. At the same time, the CO partial pressure in the atmosphere inside the furnace is lowered. Accordingly, the degree of oxidation of the slag can be blowed and the yields of iron and Mn can be enhanced, particularly in the case of melting a low carbon steel.

Abstract: PURPOSE: To prevent wrong recording of lap time or the like, by announcing the lap time or lapse time with a sound.  
     CONSTITUTION: A key TK for a stop watch is operated to set a T type FFTF. A monostable multivibrator A 2  is triggered when a key LK for lap time is closed while a lapse time counter C 2  is counting a one-second signal. As a result, an RS type FFF is set and the lapse time count output of the counter C 2  stored in a memory register R through AND gates G 3 , G 4  is transferred to a buffer register R 0  through a shift pulse generation circuit S. The lap time or lapse time is announced by a sound from a loudspeaker SP through a sound output control circuit VCC depending on the transferred data. The FFF is reset through a comparator C 3  at the end of sound output for required digits to complete a series of sound output. Wrong recording of the lap time or the like is prevented by the sound announcement.
