Title: Nonvolatile-residue concentration monitor in liquid to be tested and method of measuring said concentration
Inventor: DEBITSUDO BII BURATSUKUFUOODO
IPC: G01N15/06
Filed: 1993-04-30
Abstract: PURPOSE: To monitor a super-pure water contamination level by, relating to the manufacture of a semiconductor device, inspecting a trace amount of solvent, and measuring its residue concentration quickly with precision. CONSTITUTION: A pump 18 delivers such carrier liquid as super-pure water, etc., continuously at a constant flow rate to a non-volatile residue monitoring device 24 through a T-shape pipe coupler 22. An injector 54 injects a solvent intermittently into the carrier liquid in the coupling pipe 22. The flow rate of the solvent is substantially smaller than that of the carrier liquid. The solvent is, for example, injected at a constant flow rate for a few minutes, to generate turbulence at a mixing value 58 in the lower stream of the pipe coupler 22, to be thoroughly mixed with the carrier liquid. Or, a small capacity injector burst-injects the solvent instantaneously, to cause laminar flow instead of turbulence, and the plug of solvent is made to flow, together with the carrier liquid, in a liquid flow, while separated from it.  In both cases, a monitoring device 24 counts the number of non-volatile residue particles in the solvent with a condensed particle counter 44, etc., and a microprocessor 48 derives a residue concentration value from the count.

Title: Wave period detection device
Inventor: HIRAKI NAOYA
IPC: G01C13/00
Filed: 1995-04-06
Abstract: PURPOSE: To accurately detect a wave period from a flight body or an aircraft flying at high altitude by detecting the wave period from the fluctuation of the intensity of signals reflected from water surface with the lapse of time, and not from the fluctuation of water surface height with the lapse of time. CONSTITUTION: A modulated wave is sent to an oscillator 21 from a sweeping signal generator 20, and a radiowave is transmitted toward water surface from the transmission antenna 22 of an aircraft. A reflected wave from the water surface is received with a receiving antenna 23 and mixed with a part of the transmitted wave through a mixer 24, thereby generating beat signals. Then, the frequency of the beat signals is counted with a beat count circuit 25, and outputted as an altitude detection output signal. On the other hand, beat signals from the mixer 24 are separately inputted to a detector 27, and converted to receiving signal intensity.  In addition, the noise-like fluctuation component of receiving signal intensity resulting from the fine fluctuation of wave surface is eliminated via a low pass filter 28, and the receiving intensity on water surface at the fluctuating position is outputted as a receiving intensity output signal 29. As a result, the period of the encounter of waves can be easily detected from the aircraft navigating at high altitude.

Abstract: PURPOSE:To perform turning over of pages promptly with simple control and enable the contour to be minimized by providing means for a set part of opened leaflets, means for turning over pages being in the transfer direction through transfer, and means for turning the set part at 180 deg.. CONSTITUTION:A sucking device 4 is moved downward so as to adsorb and lift the page being in the transfer direction at set part 2 and transfer of the set part is started. Then, since the attracted page held by the sucking device 4 is drawn in the opposite direction of the set part 2 through transfer of the set part 2 and the set part 2 is still continued to transfer, the attracted page comes out of the sucking device and turning over of the first page is completed. Next, after the set part 2 is turned at 180 deg., the set part 2 is transferred so that he sucking device comes on the page in the transfer direction of the set part 2. In the next place, the sucking device 4 is moved downward so as to attract and lift the page in the transfer direction of the set part 2 and transfer of the set part 2 is started again. In the operation like the first page, the adsorbed page held by the sucking device 4 is drawn in the opposite direction of the set part 2 through transfer of the set part 2, whereby turning over of the second page is completed.

Title: Document transfer method of facsimile
Inventor: TANAKA MASAO
IPC: H04N1/00
Filed: 1981-07-04
Abstract: PURPOSE:To prevent a midway transfer of document at the time of restarts, by driving a document discharge roller at first so as to disharge a remaining document on the way, if such one is detected by a sensor, and by driving a document feed roller through detection of documents staying on the document support after confirming the discharge of the remaining document. CONSTITUTION:When a document remains at the location of a document feed sensor 8 during power-on, a document roller and a document discharge roller 4 are rotated by motors M1 and M2 through the detection signal of a sensor 8 and the remaining document is discharged. When the remaining document is located at a discharge sensor 9, a discharge roller 4 is rotated to discharge the document. When the document is discharged and the sensors 8 and 9 are de- energized, the rollers 1 and 4 come to a halt. When a sensor 11 detects a document on a document support 2, the unit starts the operation and then the rollers 1 and 4 are rotated, thereby starting the feed of document. This construction prevents a midway transfer of the remaining document and paper jam.

IPC: G05B11/36
Filed: 1978-08-30
Abstract: PURPOSE: To make it possible to obtain a control signal output of more bits without reference to the number of bits of an input signal by obtaining a controlled variable by adding or subtracting, one by one, corresponding to a digital signal shifted by a fixed value and a control variable one cycle before.  
     CONSTITUTION: A digital input signal, after being stored temporarily in RAM9, is transferred by a clock signal to shift register 10, where it is delayed by one colck signal, and the output of shift register 10 is transferred to comparator 13, where it is compared with a no-delay signal applied direct from RAM. According to the comparison result, a signal of "1", "0" or "-1" applied to operator 11 is added to a one-cycle preceding controlled variable read out from RAM15, thereby extracting a digital control signal from output terminal 12. Consequently, the number of bits of the control signal can be increased without reference to the number of bits of the A/D converter.

Title: Mobile robot
Inventor: NISHIKAWA TOMOJI
IPC: G05D1/02
Filed: 1989-04-25
Abstract: PURPOSE:To apply a tape system having high stability to sun a tape in a place where the tape can run and then to apply an ultrasonic system in a place where the tape cannot be stuck respectively by preparing a run control means applying the tape system, a run control system applying the ultrasonic system, and a switch means which performs the switch between those two control means. CONSTITUTION:A CPU 10 receives the node number of its destination from a control station and retrieves an optimum route based on the map information stored in a map memory 13 to decide the nodes to be passed through before arrival at the destination. Then the CPU 10 reads the scene data out of a scene table corresponding to a pair of a node where the CPU 10 stays at present and a node to which the CPU 10 is going to move. Thus the CPU 10 travels to the next node by a tape run system when the scene data is equal to a tape code. When the scene data is not equal to a tape code, the CPU 10 runs to the next node by an ultrasonic driving system. As a result, the CPU 10 can run with high stability and a small error caused against a prescribed running course even in a place where a tape cannot be stuck.

Title: Magnetic core for normal mode noise filter
Inventor: YOSHIZAWA KATSUTO
IPC: H01F3/04
Filed: 1983-06-13
Abstract: PURPOSE:To obtain a normal mode noise filter core with excellent DC superposition characteristics and frequency characteristics of impedance by introducing an amorphous core with a gap instead of a conventional dust core such as ferrite core. CONSTITUTION:When an amorphous core is subjected to a heat treatment, the amorphous becomes brittle and the core is hard to cut under that condition. Therefore, the core is impregnated with a resin of epoxy system or the like. Sometimes a gap of the amorphous core changes after cutting. Therefore, a non- magnetic spacer is provided to the gap part so that the dispersion of characteristics and the change of the characteristics caused by an impact can be avoided. Moreover, by coating of an insulation resin applied on the amorphous core, insulation against a winding and strength of the core are improved and the deterioration of the characteristics is avoided.
