Title: Treating method for metal-containing waste water
Inventor: OOTSUBO MITSUSAKU
IPC: C02F1/04
Filed: 1978-10-18
Abstract: PURPOSE: To obtain distilled water containing no metal salts practically by preventing the evaporation of salts by the distillation at ordinary pressure of waste water containing the salts of such metals as chromium, copper, etc., in a specific still wall- contact temperature range.  
     CONSTITUTION: A waste water containing metal salts, e.g., chrome-, copper-, and nickel-plating waste waters, etc., is regulated its pH to 6 to 8 and then subjected to an ordinary pressure-distillation at a still wall-contact temperature of 90W110°C. Thus, because the evaporation of metal salts is made impossible, the separation of practically metal salts-free good quality distilled water from enriched metal salts solution can be attained, and the separated distilled water can be reused.

Title: Inclination/vibration switch and inclination angle adjusting tool for it
Inventor: NAKAJIMA FUMIO
IPC: H01H35/02
Filed: 1993-04-30
Abstract: PURPOSE: To provide an inclination/vibration switch which can sense the inclination and/or vibrations of a consumer or industrial electric appliance by accommodating a conductive moving member in a casing composed of the first and the second electrode and an insulating member. CONSTITUTION: A conductive moving member 15 in a spherical form is placed on a recessed placing part 13A1 of the second electrode 13. When an inclination/ vibration switch concerned 10 is at a standstill vertically, the moving member 15 contacts only this electrode 13 and not the first electrode 11 which is insulated with an insulating member 12, so that the Off condition is generated. When vibration is applied to the switch 10 or it is inclined, the moving meer 15 makes movement to result in touching also with the first electrode 11, so that the On condition is generated and it senses the vibrations or inclination. Because the electrodes 11, 13 are in a columnar shape, inclination and vibration in all directions can be sensed. The angle of the inclined surface of the placing part 13A1 is set as desired in accordance with the magnitude of the vibration.

Title: Inverter
Inventor: CHIHARA YASUYUKI
IPC: H02P27/06
Filed: 1985-06-13
Abstract: PURPOSE:To enable to detect an effective value of a current which flows to a compressor without depending upon a frequency and an environmental temperature by inserting a fixed resistor into one phase to detect the surface temperature of the resistor. CONSTITUTION:When a frequency converter 1 is driven by a compressor 2, a fixed resistor 7 is inserted into one phase of the compressor 2. When a current flows to the compressor 2, the resistor 7 generates a heat loss so that the surface temperature rises. A controller 5 detects the difference of the surface temperature of a fixed resistor 9 by a temperature sensor 3 to obtain the effective value of a current which flows to the compressor. A frequency converter 1 is controlled in the sequence determined by the effective value of the current.

Title: Inclination oriented ring-shaped permanent magnet and manufacture thereof
Inventor: YAMAGAMI TOSHIAKI
IPC: H01F7/02
Filed: 1990-05-18
Abstract: PURPOSE:To enable high surface magnetic flux density to be taken out even if multipole magnetization is performed by fusing and casting the alloy, whose basic ingredients are a rare earth element (but yttrium included), a transition metal element, and boron, so as to make an ingot, and then molding it by extrusion at a specified temperature so as to form an anisotropic permanent magnet. CONSTITUTION:Alloy, consisting of the basic ingredients of a rare earth element (but yttrium included), a transition metal, and boron, is fused and cast to make an ingot, and this cast ingot is hot-worked at a temperature of 500 deg.C or more to give it magnetic anisotropy. That is, since the ring-shaped ingot is covered with a sheath, and hot-extrusion-processing is applied at a temperature of 500 deg.C or more, the surface part is processed strongly and the center part is hardly processed, so the ingot surface is oriented more, and the center part is left anisotropic. Hereby, high surface magnetic flux density expected of a rare earth magnet can be taken out even if high split multiple magnetization is performed.

Abstract: PURPOSE:To eliminate the need for complicate operation and a large-scale device and to measure the accurate pour point of a sample by applying pressure to the sample put in a sample container, and allowing a pressure measuring mechanism to detect the rise of the sample in a vent pipe. CONSTITUTION:When pressurized air presses the surface of the sample S, the sample S rises in the vent pipe 4 and a pressure application detector 7 detects the rise in liquid level. Then, when the detector 7 detects it, solenoid valves 13 and 15 are closed and solenoid valves 19 and 20 are opened to return the sample to the state before the pressure application while the temperature begins to be displayed. Further, when the temperature of the sample S drops by, for example, 1 deg.C, the display is stopped again and the pressure applying and detecting operation is performed. This operation is repeated until the detector 7 does not detects fluctuations of the surface of the sample S. Then, when the fluctuations are not detected any more, the temperature display is stopped 5sec later, and in this state the solenoid valves 13 and 15 are closed and the solenoid valves 19 and 20 are opened to stop cooling. The temperature displayed at this time is a freezing point and 1 deg.C is added to this value to obtain the pour point.

Title: Optical disk device
Inventor: ARAI AKIHIRO
IPC: G11B7/00
Filed: 1991-05-31
Abstract: PURPOSE:To perform stable and accurate tracking control by detecting the depth information and reflection factor of a track groove. CONSTITUTION:A system controller 21 controls a tracking control part 10 to move a laser spot in a direction perpendicular to the track, and a signal TE2 oscillates the laer spot so as to move across the track. This amplitude is compared with a designated value in a comparison part 19, and a selector 20 is instructed so that the signal TE2 is outputted to the control part 10 when the amplitude is larger than the designated value, or a signal PTE is outputted to the control part 10 when smaller. Since the amplitude of the signal TE2 reflects the depth of the track groove, a guiding groove having a depth of lambda/8 can be discriminated from the groove having a depth ranged from lambda/4 to lambda/6. Accordingly, when a control means suitable for an optical disk to be reproduced is selected, forced control of the control part 10 by the controller 21 is interrupted and a selector 20 outputs any of the signals PTE and TE2 to the control part 10. Thus, the stable and acurate tracking control can be performed regardless of the type of optical disk.

Abstract: PURPOSE:To realize a high-speed pulse response by a method wherein a resonance Raman beam is generated at a semiconductor laser for pulse-response use by using pumping light which is output by a semiconductor laser for pumping light generation and the semiconductor laser for pulse-response use is laser-oscillated. CONSTITUTION:A semiconductor laser 1 for pulse-beam generation use is faced with a semiconductor laser 2 for pumping light generation; they are arranged in such a way that a beam radiated from the laser 2 can sufficiently enter into the waveguide of the laser 1. When a DC electric current bias is applied to the laser 2, pumping light 22 is generated, enters into the laser 1 and generates longitudinal optical phonons; and a Stokes-shifted Raman beam is generated.

Then, a pulse current source 3 is connected to the laser 1; and the laser is pulse-driven and a pulse beam is generated. When the pulse beam is increased or decreased, a resonance Raman scattering intensity is increased or decreased, and a pulse-modulated resonance Raman beam is generated. Thereby, a high-speed modulation can be executed, and a high-speed pulse response can be obtained.
