Title: Ring trip circuit
Inventor: MINAMITANI EIJI
IPC: H04M3/02
Filed: 1980-08-11
Abstract: PURPOSE:To perform ring trip, by utilizing the fact that the time when a callout signal value exceeds a threshold value is different depending on response or nonresponse, and discriminating if the callout signal value exceeds the threshold value at a certain time point. CONSTITUTION:Normally, a flip-flop FF is at set state and an output Q is at 1, a relay RL is operated with a callout signal transmission instruction SD and a callout signal is transmitted. A photocoupler PH1 has a threshold current IT and an input D of the flip-flop FF is zero when a current exceeding this threshold value flows. When a called party responds, a current by a power supply -V is added and the period exceeding the threshold value IR is increased. Within the increased period, an output 1 is inputted to a clock terminal CL of the flip-flop FF from the reference  time point forming section RF. If a clock input is present when the called party  responds, since the input D is 0, the flip-flop FF is reset, the relay RL is restored and the transmission of the callout signal can be stopped.

Title: Detector for noise in voice band
Inventor: TAKAGI KUSUO
IPC: G01R29/08
Filed: 1988-05-06
Abstract: PURPOSE:To miniaturize the title detector and to detect noises in an environmental magnetic field considering acoustic sense characteristic by detecting both signals based on a continuous sine wave magnetic field and a pulse magnetic field. CONSTITUTION:The environmental magnetic field including the continuous sine wave magnetic field which becomes the noise in the voice band and the pulse magnetic field related to the repetition period of a commercial power source is detected 1 and the output signal is supplied to an acoustic sense correction means 2 and a BPF 3. Since the means 2 possesses the characteristic opposed to frequency characteristic at an acoustic sense limit level, a 1st detection signal based on the continuous sine wave magnetic field can be obtained. The signal level is compared with a 1st set level and a 1st output signal is generated from a 1st comparison means 4. The pass frequency of the BPF 3 becomes the desirable frequency related to the frequency of the commercial power source, so that a 2nd detection signal based on the pulse magnetic field by the repetition period of the commercial power source can be obtained. By comparing the signal with a 2nd set level, a 2nd output signal can be obtained from a 2nd comparison means 5. The noises caused by the environmental magnetic field can be detected with the 1st and the 2nd output signals, whereas the constitution is miniaturized and the detection of the noises considering the acoustic sense level can be possible.

Inventor: HATANO KAORU
IPC: G01N33/18
Filed: 1998-04-21

IPC: H04L7/00
Filed: 1977-09-16
Abstract: PURPOSE:To eliminate the need of a timing adjustment in each station by enabling one station to make an automatic adjustment of timing according to the variation in line length of the circuit. CONSTITUTION:When a plural number of stations are on a loop circuit, timing regulator 20 of one station makes an automatic adjustment of timing as the line length of the loop circuit varies. Namely, phase detector 22 is supplied with signal T10 from timing generator 21 via connection line 77 and with signal T11 from receiver 27 via connection line 76. This signal T11 is the signal obained by delay signal T10 by the loop circuit of timing line 61, driver circuit 24 and receiver 27 and detector 22 detects phase difference TD between both the signals to obtain delay time TD1, which is transmitted to delay device 23 to control the delay time. Consequently, an automatic adjustment of timing is done in one station as the line length of the circuit varies, so that the timing adjustment of each station can be omitted.

CONSTITUTION:An RIM material is cast into a cavity 5 of a surface layer part of a design surface of an RIM mold constituted of a top and bottom forces 1, 3 through a mixing head 6 and a surface layer part 11 of the design surface is molded. Since the surface layer part 11 is molded by turning the design surface down, it is not feared that unevenness of the surface following upon a bubble is generated. Then a fiber reinforcing material 15 is loaded on the rear of the surface layer part 11 of the design surface under a state where the surface layer part 11 of the design surface is left behind in the bottom force 1 and a mold is clamped. The RIM material is cast similarly into a cavity 7 of a laying part of the reinforcing material to be formed through the mixing head 6 for formation of a laying part 13 of the reinforcing material. Since joining between the surface layer part 11 of the design surface and the laying part 13 of the reinforcing material is performed with the same material, sufficient joining strength is obtained by fusion and coaction with crosslinking.

Title: Hot water and water mixing device
Inventor: YONEKUBO HIROAKI
IPC: F16K31/64
Filed: 1986-05-15
Abstract: PURPOSE:To prevent the hunting of a hot water/water mixture temperature especially at the time of high pressure, by controlling the gain of a controller in response to the levels of the water pressure and hot water pressure to change the setting level of the hot water/water mixture temperature setter and the driving speed of an electrical drive means against the deviation of said mixture temperature. CONSTITUTION:The difference between the hot water pressure and the water pressure is controlled by a pressure balance valve 24. However the slight pulsation remains with pressure of both water and hot water and therefore the slight fluctuation is liable to occur also with the hot water/water mixture temperature which is detected by a thermistor 34. Here a controller 39 works to control the mixture ratio to suppress said fluctuation. In addition, the levels of both water pressure and hot water pressure can be controlled in three steps by a gain controller 40. Thus the driving speed of a motor is set at a low level with a high level of pressure and at a high level with a low level of pressure in response to said three steps and against the temperature deviation, i.e., the difference between the hot water/water mixture temperature set by a setter 38 and that detected by the thermistor 34.
