Title: Generating device of driving signal for motor
Inventor: SAWAMURA AKIRA
IPC: H02P5/00
Filed: 1981-10-05
Abstract: PURPOSE:To simplify a circuit constitution and to avoid the effect of noise by the omission of wirings laid to phase angle sensors, by a constitution wherein the phase angle sensors are made unitary and formed into IC irrespective of the number of phases. CONSTITUTION:A phase detection signal is given to an input terminal 12 from a unitary phase detecting sensor provided at a three-phase motor, and it is given as a trigger signal to an indented-wave generating circuit 14 and simultaneously as a sample pulse to a sample hold circuit 16. The indented-wave generating circuit 14 and the sample hold circuit 16 form a frequency-voltage converting circuit converting the frequency of an input signal to a voltage. A phase-shifting circuit 18 forms two or more phase-shift signals shifted for each set phase in relation to the phase of a unitary input signal given to the input terminal 12. Each phase-shift signal obtained in this phase-shift circuit 18 is combined to form a motor driving signal by a motor driving signal forming circuit 42.

Title: Bathtub water purification apparatus
Inventor: NAGAYOSHI SEIYA
IPC: A47K3/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent backwashing from being started during bathing by prohibiting the backwashing of a cleaning tank during the detection bathing of a man or during the prescribed time since the bathing is no longer detected after once detection of the bathing of the man. SOLUTION: When the bathing of the man is detected by a bathing detecting means 32, the information is transmitted to a backwashing prohibition judgment means 44 which instructs a backwashing operation control means 28 to prohibit the start of the backwashing operation. Namely, the backwashing is prohibited during the bathing of the man even if the backwashing start conditions hold. Whether the person is under bathing or not is judged by the bathing detecting means 32. When the backwashing operation control means 28 judges that the integrated time of on of a pump 1 attains the prescribed time or above during the not bathing and a timing for starting the backwashing is reached, a selector valve control means 27 moves a selector valve 9 to a backwashing position and controls the operation of the pump 1 at a prescribed number of revolutions in the state, thereby executing the backwashing of the cleaning tank. When the backwashing of the prescribed time ends thereafter, the selector valve 9 returns to a purification operation position and the purification operation is started.

Title: Subscriber supervisory method and subscriber circuit in electronic exchange system
Inventor: USUHA SHINJI
IPC: H04M3/30
Filed: 1990-06-19
Abstract: PURPOSE:To quantitatively grasp the stability of the communication state of a ping-pong transmission subscriber and to improve the maintenance of an existed cable by supervising the state of a subscriber line based on gain control information and delay time information in the subscriber line. CONSTITUTION:The transmission loss of the subscriber line 4 is learnt by extracting gain control information showing the attenuation quantity of an input waveform from a gain control means 22 compensating the attenuation of a received waveform in a subscriber circuit. Furthermore, the delay time of a signal is learnt by counting time from respective start points of the burst repetition period of a network to the reception of an opposite burst signal. Information showing the cable characteristic of the subscriber line 4 is informed to the central processing unit of an electronic exchange system. Consequently, the state of the subscriber line 4 can quantitavely be learnt on a station-side. Thus, the effective margin of ping-pong transmission is captured and maintenance improves in the existed line where the type of the line, the diameter of the line and the presence or absence of cable mix are not clear.

Title: Roll for heat recovery
Inventor: NAKAMURA TERUHISA
IPC: C21D9/573
Filed: 1981-10-06
Abstract: PURPOSE:To efficiently recover heat directly from a metal band or the like, by providing a hollow roll in which liquid is enclosed and whose internal pressure is reduced and by providing a hollow shaft in the roll and fitting the shaft with a heat exchange pipe so that the pipe is out of contact with the cenclosed liquid and a heat recovering fluid is caused to flow through the hollow shaft and the pipe. CONSTITUTION:A hollow shaft 4, a part of which is closed with partition plates 2, 2a so that an internal opening 3 is defined, is hermetically secured in a hollow roll 1. The pressure in the hollow roll 1 is reduced and liquid 9 such as methyl alcohol is enclosed in the roll. A spiral heat exchange pipe 6 is fitted around the hollow shaft 4 so that the pipe communicates with the interior of the shaft through holes 5, 5a. Heat in a metal band is transferred into the hollow roll 1 because of their direct contact and the liquid 9 is easily evaporated because of the pressure reduction. A heat recovering fluid flowing from an inlet port 7 to an outlet port 8 through the hollow shaft 4 absorbs heat from the evaporated liquid 9 so that the vapor is liquefied. The heat in the metal band is thus efficiently recovered.

Title: Device for preventing nozzle block in sand lifting device
Inventor: ICHIKAWA KIYOSHI
IPC: B01D21/24
Filed: 1991-06-03
Abstract: PURPOSE:To prevent the block of a jet nozzle even at the time of the stoppage of a sand lifting operation by providing a fluid supply part, which can supply and stop a fluid, between a sand lifting part and a sand intake port. CONSTITUTION:The sand lifting part 130 is provided in the middle of a sand lifting pipe 114, and the fluid supply part 132 is provided between the sand lifting part 130 and the sand intake port 131. To the fluid supply part 132, a fluid pipe 139 is connected via a valve 138. At the time of the stoppage of the sand lifting, while continuing a jet stream supply upward by a high pressure water via the high pressure pipe 142 of the sand lifting part 130, a fluid such as air and water is supplied from the fluid supply part 132. Since the fluid has a lighter specific gravity than the water containing sand, only the fluid is lifted through the sand lifting pipe 114 and the sand lifting operation is not performed. Consequently, the sand inside the sand lifting pipe 114 is discharged together with the fluid, and the inside of the sand lifting pipe 114 is the fluid only which is supplied from the sand supply part 130 and the fluid supply part 132. When the sand lifting operation is stopped in this state, the jet nozzle 140, etc., is not blocked by the back flow of the sand inside the sand lifting pipe 114.

Filed: 1983-08-31
Abstract: PURPOSE:To make a crystal piece or the like unnecessary and to reduce the cost detecting respective frequencies of an FSK signal independently of one another with band-pass filters to constitute a carrier collision detecting circuit. CONSTITUTION:Frequencies f1' and f2' of a down signal V2 consisting of an FSK signal Fs inputted to a receiving circuit 4b are converted to intermediate frequencies f1'' and f2'' through a front end 7, and they are extracted by band- pass filters 12a and 12b. These extracted signals are supplied to carrier detecting circuits 14a and 14b through amplifiers 13a and 13b respectively to detect whether there are carriers or not. If both carrier signals are absent, a decoding circuit 17 decides that the device is not in the data transmission state; but if both carrier signals are present, the circuit 17 discriminates that data are transmitted from plural terminals simultaneously. If only one carrier signal is detected, the circuit 17 decides that data is transmitted but collision does not occur.
