Title: Data responding device
Inventor: ISHIBASHI YOSHITO
IPC: H04B1/59
Filed: 1994-12-02
Abstract: PURPOSE: To surely perform a response while using a pseudo random system signal without losing any signal even when the coil winding directions of a reader and plural responders are not fixed. CONSTITUTION: When starting the transmission of a transmitter/receiver (reader) 10, a pseudo random system signal generating part 40 generates the pseudo random system signal and transmits it by driving a coil 20. A responder (data storage medium) 12 calculates self-correlation between the received signal from the transmitter/-receiver 10 and the same reference pseudo random system signal as the transmitter/receiver 10 by using a correlation arithmetic part 42 and detects the code of a provided correlative value by using a code detecting part 44.  When the detected code is positive, under the control of a phase control part 46, the pseudo random system signal converted corresponding to a response data bit is returned as it is but when the detected code is negative, the opposite winding direction of the coil is judged and the pseudo random system signal generated corresponding to the response data bit is returned after its phase is inverted.

Inventor: HISHITANI KAZUNOBU
IPC: B30B9/24
Filed: 1993-11-30
Abstract: PURPOSE:To maintain the specified moisture content of dehydrated cake and to attain a target processing quantity by detecting the cake thickness and filter cloth traveling speed of a gravity filter section and controlling a filter cloth speed and/or sludge supply rate. CONSTITUTION:The flocculated sludge is supplied to the gravity filtration zone 3 of the dehydrating machine 2 by a piping 13. The flocculated sludge is gravity filtered and is made into gravity filtered cake. The thickness of the gravity filtered cake and the filter cloth traveling speed are measured and the results thereof are inputted to a dehydration control section 7. Such fresh filter cloth traveling speed at which the cake thickness attains the target value is calculated from the difference of the measured value of the cake thickness and the target value and the measured value of the filter cloth traveling speed. The filter cloth traveling speed is changed if the fresh filter cloth traveling speed is within the control range of the previously set filter cloth traveling speed. The sludge supply rate is so changed that the filter cloth traveling speed restores the value within the control range if the filter cloth traveling speed described above deviates from the control range.

Title: Output level control circuit
Inventor: IZUMI ISAO
IPC: H03G11/08
Filed: 1990-11-06
Abstract: PURPOSE:To suppress an overshoot at the time of the rising of a burst-shaped signal by clipping the output of a comparator and amplifier which controls the gain of an amplifier. CONSTITUTION:This circuit is equipped with a clipping circuit 4 which restricts the amplified output of a comparator and amplifier 3 to be in a clipping level decided corresponding to a preliminarily decided voltage. That is, when the output amplitude of the comparator and amplifier 3 is almost beyond the clipping level of a value corresponding to a reference voltage Vref, a diode 43 is conducted, and the output amplitude of the comparator and amplifier 3 is controlled to be in the clipping level. Thus, the gain of an output amplifier 1 is not beyond the gain corresponding to the clipping level, and a waveform distortion such as the overshoot can not be generated at the time of the rising of the output of the output amplifier 1.

Title: Rotation angle sensor
Inventor: SAITO YASUO
IPC: G01D5/24
Filed: 1990-11-06
Abstract: PURPOSE:To improve the detecting accuracy by providing a rotary cylinder, a first and a second conductive fixed cylinders, and securing a large electric capacity by the enlargement of the area, and holding the gap between the cylinders constant. CONSTITUTION:A rotary cylinder 4 is mounted to a rotary shaft 2, and a first conductive fixed cylinder 5 and a second conductive fixed cylinder 6 are concentrically provided in the inner peripheral surface and the outer peripheral surface of the cylinder 4 with gaps (a) and (b) from the cylinder 4, respectively. In accordance with the rotation of the shaft 2, the electric capacity corresponding to the displacement of the rotating cylinder 4 is changed, from which the rotating angle of the shaft 2 is detected. Since the cylinders 4, 5, 6 are circular cylinders, if the diameter or the length in the direction of a generator of the cylinder is increased, the electrode area can be set large, thus reducing the adverse influences of the floating capacity. Moreover, the cylinders are difficult to be deflected because of the circular shape. Accordingly, the gaps (a), (b) can be maintained constant with high accuracy, so that the rotating angle can be detected with high accuracy.

Title: Semiconductor laser device
Inventor: TAKAMI AKIHIRO
IPC: H01S5/12
Filed: 1986-12-16
Abstract: PURPOSE:To improve the characteristics of a diffraction grating by so forming an active layer that a multiple quantum well structure section and a mixed crystal section are regularly repeated in a resonator direction. CONSTITUTION:An active layer 4 of a structure in which a mixed crystal section 4B and a multiple quantum well structure section 4A are regularly repeated in a resonator direction is provided, and the layer 4 is utilized as a diffraction grating. The structure section 4A is made of a GaAs-AlGaAs hetero junction on which an N-type AlGaAs clad layer 2 is grown, and the mixed crystal section 4B is formed by selectively implanting Si ions in a direction substantially perpendicular to the section 4A and annealing it. Then, a P-type AlGaAs clad layer 5 is crystal-grown on a protective layer on the section 4A. Since the refractive index of the section 4A is reduced by mixed crystallization, if the mixed crystallization is controlled at a pitch of approx. 3000Angstrom , the periodic change of the refractive index can be obtained. Since such a periodic change of the refractive index is of a regular array of reflectors having different refractive indexes, it operates as a diffraction grating.

Title: Component feeder
Inventor: KATO EIICHI
IPC: H05K13/02
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To surely chuck a chip part through a vacuum nozzle by closing a shutter plate only when the vacuum nozzle chucks the chip part. SOLUTION: An external signal rises to drive a solenoid 35 at this timing, drawing a drive cylinder forwards. The movement of the cylinder rotates a shutter driving arm 34, sliding a shutter plate 32. The sliding of the plate 32 opens a shatter opening 31 to expose outside a top chip part fixed to a carrier tape 21. As a result this allows this chip device to be chucked e.g. by a vacuum nozzle of an outside disposed electronic mounting machine. Before the chip part reaches a vacuum chuck position, it never deviates from its arranged position of the carrier tape, if affected by the suction flow by the nozzle. Thus the chip part can be surely chuck by the vacuum nozzle.

Title: Hot wire type air flowmeter
Inventor: YONEDA HIROSHI
IPC: G01F1/68
Filed: 1988-11-30
Abstract: PURPOSE:To avoid effect on a voltage control oscillator by providing a low-pass filter between a constant temperature control circuit and an output voltage adjusting circuit within a voltage output type hot wire type air flowmeter. CONSTITUTION:Current IH flowing through a hot wire 105 is detected with a resistance 106 to serve output signal V2 of a constant temperature control circuit 1. Here, when an air flow vibrates by a turbulence or the like, the V2 fluctuates as well and so, the fluctuation of the V2 is suppressed with a low-pass filter 2 down to a VF. The VF is amplified with a differential amplifier 304 of an output adjusting circuit 3 to match characteristic of a voltage control oscillator 4 at the rear stage. This enables suppression of a variation in a frequency output due to vibration of an air flow without affecting the constant temperature control circuit 1 and the voltage control oscillator 4.

Patent JP-H01139957-A (JP)
Title: Cooling device
Inventor: KIDA TAKUMI
IPC: F25B5/00
Filed: 1987-11-27
Abstract: PURPOSE:To prevent a mechanical vibration and a noise from being generated by a method wherein an electrical current is generated between some electrodes in coolant pipes and a high magnetic field is generated by a superconductive coil. CONSTITUTION:For example, in case that only one of evaporators 7, 7' is operated, a two-way valve at an inlet of an evaporator to be operated is opened and another two-way valve at another inlet of another evaporator to be stopped is closed. A switch 18 for a fluid pump 11 is closed and another switch 18' is opened. In this case, coolant within a coolant pipe 12b at a fluid pump 11 is ionized by a positive electrode 15 and a negative electrode 16 and then an electrical current is flowed from the electrode 15 to the electrode 16. In turn, a strong magnetic flux is generated between the super conductive coils 13 and 14 from a super conductive coil 13 to a super conductive coil 14. Due to this fact, a Lorentz force is generated by an electric current flowing between the electrodes 15 and 16 and a magnetic flux between the super conductive coils 13 and 14. The ionized coolant is moved toward the condenser 2, a flow of the coolant is produced and then this is circulated within a cooling device 10. In this way, since an electromagnetic flow of coolant is generated by Lorentz force, any mechanical vibration and noise may not be generated.

Title: Device for bubble removing from passage of liquid
Inventor: NAGASAKI SUSUMU
IPC: G01N35/08
Filed: 1990-11-07
Abstract: PURPOSE:To remove a bubble from a flow passage of a liquid without fail by a method wherein the bubble is detected from a difference between detected values of electrostatic capacity sensors provided at two positions in the upstream of the flow passage and the liquid containing the bubble is made to flow to a bypass flow passage by a selector valve. CONSTITUTION:When a bubble 18 is mixed in a mixture liquid 17, only an electrostatic capacity sensor 10 detects the electrostatic capacity of the bubble 18 and a difference occurs between output signals of two sensors 10 and 11. An amplifier 12 detecting this difference transmits it to a control means 16 and the means 16 operates a selector valve 13. Thereby the mixture liquid 17 containing the bubble 18 is made to flow to a bypass flow passage 14 and it does not flow to a light emission detecting element. Accordingly, the bubble 18 can be removed from the mixture liquid 17 without fail and false measurement of the quantity of emitted light caused by that the bubble 18 is contained in the mixture liquid 17 is eliminated. Besides, the means 16 is made to be of a timer system. After a prescribed time passes, therefore, it restores the valve 13 to the former state, the valve makes the mixture liquid 17 flow to the light emission detecting element and thereby the quantity of emitted light is measured.

Filed: 1989-11-20
Abstract: PURPOSE:To send a composite mail even to a recipient not having a terminal equipment handling the composite mail by providing a terminal list with information of terminal equipment able to receive a composite mail unable to receive due to difference of media described thereon. CONSTITUTION:When a mail 10 not distributed from a terminal equipment 13 to a terminal equipment 11 due to difference from media is sent, the terminal equipment 11 receives the mail 10 tentatively and references a terminal list 14. When a mail not received due to difference from the medium is sent to each reception terminal equipment connecting to the electronic mail system, the terminal list informs information name of all terminal equipments enabling the reception of the mail, medium of the mail to be handled and attribute or the like. Thus, the terminal equipment 11 transfers the mail 10 tentatively received to the terminal equipment 12 informed from the list 14, then the disabled distribution of the mail is avoided.

Abstract: PURPOSE:To always and easily confirm the working of a peripheral input/output circuit by executing a test program when a test program branch instruction is given in a deciding step and delivering the executing result of the test program to an original control output circuit. CONSTITUTION:A test program 1 is executed when switches 8 and 9 are closed respectively. In other words, the read and digitized analog signal input data is delivered to a control output circuit part 6. Then a test program 2 is carried out when the switch 9 is opened. In other words, the switch input state of an input terminal group 4 for said switch signals is delivered to the part 6.
