Title: Production of quaternary calcium phosphate
Inventor: HIRANO MASAHIRO
IPC: C04B12/02
Filed: 1993-05-20
Abstract: PURPOSE:To obtain a quaternary calcium phosphate of improved mechanical strength by wet synthesis of raw material component containing Ca feedstock and P feedstock to produce a feedstock slurry, and then evaporating to dryness followed by calcination and full-scale baking operation at respectively specified temperature. CONSTITUTION:A specified amount of a Ca feedstock such as CaCl2 is added to water and dissolved by agitation. A P feedstock such as H3PO4 in such an amount as to be 1.95-2.00 in the molar ratio Ca/P is dissolved in water and the resultant solution is dripped under agitation into the aqueous solution of the Ca feedstock to carry out reaction under mixing to prepare a feedstock slurry.

Title: Control device for induction motor
Inventor: BANBA TADAYOSHI
IPC: H02P27/06
Filed: 1978-09-27
Abstract: PURPOSE: To control a motor stably and at a constant power level, by controlling a voltage-power ratio constantly until the basic r.p.m. of a motor is reached, and by changing the type of control from the voltage control to the r.p.m. control.  
     CONSTITUTION: A speed instruction is given by a speed setting unit 3, and the r.p.m. of a motor 2 reaches the instructed speed after the time set by an acceleration and deceleration regulator 4. If the speed instruction indicates the r.p.m. below the basic r.p.m., limiting action of a voltage limiter 6 is not actuated, and the output voltage and frequency of an invertor are limited to the constant ratio resulted from the comparison of the speed-instruction signal and the output voltage V. If the speed instruction is set above the basic r.p.m., the voltage limiter initiates the limiting action, and the output voltage of the inverter becomes constant regardless of the instruction. In this constitution, since the constant V/F control is made up to the basic r.p.m. of the motor, and the control is changed from the voltage control to the r.p.m. control in the region beyond the basic r.p.m., the stable control and the constant-power control of a motor can be made.

Title: Prevention of color development of aromatic compound having hydroxyl group
Inventor: YANO NAOYUKI
IPC: C07C37/88
Filed: 1979-09-19
Abstract: PURPOSE: To maintain the quality of a substance having a hydroxyl group and liable to color during storage, e.g. β-naphthol, and to prevent the color developement of the substance, by keeping the substance in a closed vessel containing an oxygen acceptor such as active iron oxide preventing direct contact of both contents.  
     CONSTITUTION: The color development of an aromatic compound having a hydroxyl group and liable to develop color with time (e.g. catechol, resorcinol, hydroquinone, phenol, naphthol, etc.) can be prevented by storing the compound in a closed vessel (keeping from the outer atmosphere) containing a substance capable of absorbing oxygen (e.g. active iron, a mixture of a dithionous acid salt and a hydrous alkaline earth metal) preventing the direct contact of both contents (e.g. placing the oxygen-absorbing substance in a breathable bag or box placed in the empty space of the vessel).  
     EFFECT: A sufficient effect can be attained by the use of only a small amount of the oxygen-absorbing substance. The purity of the product can be maintained at a high level because there is not contamination of the product with the oxygen-absorbing substance.

Filed: 1989-05-12
Abstract: PURPOSE:To form a thin nitrided film having superior adhesive strength by producing an electron beam while introducing a gaseous mixture of argon and nitrogen into a hollow cathode and reducing the partial pressure of argon to nitrogen in a vacuum vessel. CONSTITUTION:A crucible 2 capable of holding evaporation material, such as metal 5, is placed in a vacuum vessel. The above crucible 2 is irradiated with an electron beam 6 by means of a hollow cathode-type electron gun 1 constituted so that arc discharge is initiated between an anode and a hollow cathode to draw electrons, by which the evaporation source is evaporated to form a film.

Title: Boat for plasma cvd equipment
Inventor: SHIMADA MASAO
IPC: H01L21/205
Filed: 1984-06-11
Abstract: PURPOSE:To allow carbon dust generated in a furnace to be suppressed without shaving stuff of a boat in removing an insulating film which adhere to a part besides a semiconductor substrate by forming an electrode on the surface of the boat in the area to which the semiconductor substrate is fixed and coating the whole surface besides the electrode with an insulating protective film. CONSTITUTION:A rigid insulating protective film 6 is composed of not entirely or scarcely etched material even if it is etched by gas plasma. When the film 6 has adhered to the whole surface of a boat including the part at which the back of a semiconductor substrate 1 contacts the boat 2, a current induced in the semiconductor substrate 1 by a high frequency current has no way of escape. Owing to this, the part at which the back of the semiconductor substrate 1, contacts the boat is not made to adhere with the protective film 6 but is made to provide conductivity. For instance, the surface of the boat 2 only in the area which the semiconductor substrate contacts is used as an electrode part 2a for generation of plasma. An Al plate 10 may be additively mounted on the surface of the boat 2 as an electrode for generation of plasma.

The means 800 has a CCD linear sensor, receives the image of the pattern 300 and converts the signals to electric signals. An operation processing means 900 computes the moving distance of the slit image of the pattern 300 and computes the corresponding tilt angles. Thus, the tilt angles of a tilt sensor 1000 are computed.

Abstract: PURPOSE: To enable an ESD circuit which can be extracted from a MOS circuit to be included by a method, wherein a region which contains two pads and a conductive layer formed on an insulating region between the two pads are provided to constitute a breakable link which operates on a wettability principle. CONSTITUTION: A breakable link 15 is composed of a region, which includes two pads 11 and 12 and a conductive layer deposited on an insulating region between the pads 11 and 12. The pads 11 and 12 tends to become wetted with the deposited conductive layer, and on the other hand, the insulating region is hardly wetted with the deposited conductive layer. When the conductive layer is melted, the wetting actions of the pads 11 and 12 separate the melted conductive layer from the insulating region in cooperation with the non-wetting action of the insulating region. As a result, the molten conductive layer is attracted to the pads 11 and 12. The molten conductive layer is separated from the insulating region, so that an electrical connection between the pads 11 and 12 is broken off.  By this setup, an electrostatic discharge(ESD) circuit 14, which can be extracted from a MOS circuit, can be included.
