Title: Preparation of high purity silicon and high purity titanium
Inventor: KARITA YOICHI
IPC: C25C3/28
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a prepn. method of a high purity silicon and a high purity titanium capable of separating a product at a lower cost than in the conventional method without necessitating high purity sodium. SOLUTION: A mixture of NaCl and a metallic salt having a lower m.p. than NaCl or a complex metallic salt forming a molten salt having a lower m.p. than NaCl is electrolyzed in a electrolyzer 1 provided with a partition 2 of β-alumina. Since Na only is transferred to a cathode side, a high purity metallic Si is produced by reacting Na with SiCl4 gas. Separation of a product can be carried out by filtration with a filter 7 at a comparably low temp. And by replacing this SiCl4 gas with TiCl4 gas, a high purity titanium can be prepared.

Title: Automotive air conditioner
Inventor: KAJINO YUUICHI
IPC: B60H1/00
Filed: 1983-12-28
Abstract: PURPOSE:To improve the comfortableness of the environmental conditions inside a vehicle by reducing the quantity of suckedout air inside the vehicle when a conditioning means is set in the cooling mode, however a cooling portion has not be cooled yet. CONSTITUTION:With an air conditioner set in the auto-mode and an air conditioner switch 60 off, a relay 46 carries no current so that the contact 46a thereof is open. Regardless of the position of a program switch 20 set among 200- 230, the current is restricted to run to a fan motor 5a via a friction switch 20b2, however, the current through the series connection of resistances 38a-38d is sent to the fan motor 5a so that the quantity of supply air is controlled to the minimum. Even if the air conditioner switch 60 remains off and a cooler core 6 has not be cooled yet in spite of a demand for cooling, uncomfortableness may be prevented since high temperature air will not be supplied inside the vehicle.

Title: Driving amplifier for solenoid type flow control valve
Inventor: ANDO TAKESHI
IPC: F16K31/06
Filed: 1986-10-21
Abstract: PURPOSE:To improve operability and controllability by containing a rising/falling delay time adjusting means which can separately adjust the rise and fall of a set signal obtained by a switching/selecting means in an amplifier unit. CONSTITUTION:A plurality of setting devices 20a-20n and switching/selecting means 22a-22n for switching/selecting the outputs from the setting devices 20a-20n are contained in an amplifier itself. The multiset of pressure and fluid is performed with the amplifier itself through only imparting outer signals to the switching/selecting means 22a-22n. Further, in the driving amplifier itself, a rising/falling delay time adjusting means 30 is provided for separately adjusting the time delay characteristic in rise and fall of the set signal. Therefore, even if response characteristics to the rise and fall of set signal in hydraulic driving load are different each other, the above driving amplifier can suitably correspond to various requires of the system.

IPC: C04B35/66
Filed: 1992-08-27
Abstract: PURPOSE:To prolong the service life of a molten metal hitting part without losing the effect of erosion resistance and slag penetrating resistance by arranging a burnt precast refractory to the molten metal hitting part and executing the flowing-work of a monolithic refractory to the surrounding thereof. CONSTITUTION:By first using the burnt precast refractory 1 to the molten steel hitting part, the structural strength is made to be strong, and if the molten steel is received to this part, the refractory structure through the surface part and the lower part is scarcely affected and therefore, the resistance to the direct hitting of the molten steel and to the heat shock at the time of receiving the molten steel is improved. In this result, even if the bottom part 3 is lined with a material, such as alumina spinel series monolithic refractory 2 having extremely large heat expansion, the crack is not developed in the molten steel hitting part and the excellent durability is obtd. Further, the reduction of repairing man-hours to the molten steel hitting part, the improvement of working ratio of the molten steel ladle and the labor saving of the lining work to the bottom part 3 with the monolithic refractory, etc., can be obtd.

Title: Cooker
Inventor: SHIBATA KATSUHISA
IPC: A47J37/06
Filed: 1990-09-19
Abstract: PURPOSE:To prevent heating when a plate is not installed and secure the contact of a heat sensitive rod with the plate when a distorsion is generated on the plate by pushing up the heat sensitive rod and attaching the heat sensitive rod with the bottom surface of the plate when the plate is installed, and installing a shielding plate for shielding a heat sensitive rod insertion passage when the plate is not installed. CONSTITUTION:One edge of a nearly L-figure shaped elastic shielding plate 15 consisting of a spring member is fixed on a heat shielding plate 17 inside the body, and the free edge is directed toward a plate 10, penetrating through the heat shielding plate 17. When the plate 7 is not placed on a cooker body 8, the shielding plate 16 closes the insertion passage for a heat sensitive rod 13 because of the springy force, and a plug 14 can not be connected. When the plate 7 is installed on the cooker body 8, a shielding plate 15 is pushed down by the bottom surface of the plate, and since the top edge of the heat sensitive rod 13 is sharp, the heat sensitive rod 13 is inserted so as to prize up the shielding plate 16 and receives the plate direction. Accordingly, the abnormal heating in the case where the plate is not installed can be prevented beforehand, and even if the plate 7 is slightly deformed by the heat, etc., the correct temperature control can be achieved by the superior contact with the heat sensitive rod 13.

Abstract: PURPOSE:To reduce a cable cost and a cable installation cost by applying frequency division multiplex to a modulation signal modulated by a data signal for monitor control into an intermediate frequency signal transmitted/received between an indoor equipment and an outdoor equipment and transmitting the multiplexed signal through one cable. CONSTITUTION:The modulator 11 of an indoor equipment 1 modulates a carrier by information to be received to output the result as a transmission intermediate frequency signal and the signal is sent through a coaxial cable 3 to an outdoor equipment 2 and amplified and then sent from an antenna 24. On the other hand, the reception signal in a microwave band is received and amplified by the antenna 24 of the outdoor equipment 2 and frequency-converted by a reception frequency converter 26 and becomes a reception intermediate frequency signal. The received intermediate frequency signal is inputted to a coaxial cable 4 via a multiplexer/demultiplexer circuit 27 and transmitted to the indoor equipment 1 and inputted to a demodulator 13 via the multiplex/demultiplex circuit 12 and becomes reception information. Thus, the exclusive cable transmitting a data signal is not required and the cable cost and the cable installation cost are reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a reflector having such a vehicle light distribution pattern that light is diffused in a horizontal direction and central luminous intensity is secured by using a predetermined reflector curve formed on a horizontal plane including an optical axis and the like as a reference curve. SOLUTION: A curve formed on a horizontal plane including an optical axis (x) and the like by a reflector is used as a reference curve 4. The curve 4 is formed of a complex curve in which hyperbolic curves and elliptic curves 4e1, 4h1, 4e2, 4h2... having focal points (f) on the optical axis (x) are alternately repeated. The closer the curves are to the optical axis (x), the larger the angles of reflection lights Q1V1, Q2V2... from a light source body C provided at a reference point in the vicinity of a focal point (f) to the optical axis (x) are set to be. A curved surface is formed as the aggregate of intersection lines produced when a virtual revolution paraboloid which has a parallel axis to a reflection light vector and takes the reference point as its focal point is cut by parallel planes to vertical planes including light beam vectors.  Thereby, a vehicle reflector diffuses light in a horizontal direction, and has a vehicle light distribution pattern with predetermined central luminous intensity.
