Title: Production of fluoride bulk single crystal
Inventor: FUKUDA TSUGUO
IPC: B01J19/06
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a production process that produces fluoride bulk single crystal of high quality from a fluoride raw material of a low purity (for example, 99.9 wt.% purity) more simply than the conventional process. SOLUTION: The powdery fluoride raw material is heated in the range from the room temperature up to a prescribed temperature over 500 deg.C under a high vacuum condition higher than 106 torr to remove moisture and oxygen in the raw materials in the furnace. After the raw material is molten, a flon gas is introduced into the single crystal-producing furnace so that the flon gas is allowed to contact with the impurities occurring on the surfaces of the melt and the solution and the impurities distributing in the melt and in the solution for a sufficient time to allow the flon gas to react with the impurities until the impurities are removed. The resultant purified melt or solution is subjected to the single crystal-growing process thereby producing the objective fluoride bulk single crystal.

Title: Simulating apparatus for manufacture of semiconductor device
Inventor: NAGASHIMA ATSUSHI
IPC: H01L21/331
Filed: 1990-06-25
Abstract: PURPOSE:To obtain a distribution of an impurity in a numerically high accuracy, by providing a means for storing the time required until a semiconductor substrate is recrystalized after implanting ions, and by providing a means for storing the regions of the impurity being distributed in the semiconductor substrate due to implanting the ions. CONSTITUTION:Data on the shape of a semiconductor substrate and model parameters are read in read-in parts, and discrete lattice points relative to numerical calculations are preset in a part 14 for setting lattice points. Based on those, the width of an insulating film is computed numerically in the process of forming the insulating film. In the next process of implanting the ions of an impurity, the distribution quantities of boron ions after implanting them at a plurality of lattice points are computed numerically. In the following process of diffusing the impurity, the quantities of boron ions to be diffused at 1100 deg.C are computed numerically at a plurality of lattice points provided on the semiconductor substrate. Hereupon, after implanting the ions, the time required until the semiconductor is recrystallized at 1100 deg.C, is read out from a part 18 for storing the time required until the semiconductor substrate is recrystallized. Then, until that time, by using the diffusion coefficient of a high speed diffusion performed in the semiconductor substrate which is made into an amorphous substrate, the diffusion of the impurity is computed numerically. Thereafter, by using the diffusion coefficient of a low speed diffusion performed in the semiconductor crystal lattice, the diffusion of the impurity is computed numerically.

Title: Controlling device of hot water storage type boiler
Inventor: KATOU SHIYOUZOU
IPC: F24H1/18
Filed: 1982-09-24
Abstract: PURPOSE:To improve the safety of the selective switch owing to the fault of the contact point by a method wherein the composite resistance circuits are composed of plural resistance elements which are provided at the different height position of a hot water storage tank respectively. CONSTITUTION:When the combustion unit 4 is operated, hot water is induced upward in a hot water storage tank 1 through a riser tube 8 and the water contained in a tank 1 is heated successively from its upper part. Accordingly, the resistance value of temperature sensitive resistance elements TH1-TH4 rapidly decrease successively from above. On this occasion, when the boiling capacity (hot water storage capacity) is set up, for instance, 50l (corresponding to the position of TH1), selective switches SW1-SW3 are all made ON, and the resultant resistance of the resultant resistance circuit 10 is determined by the value of four of temperature sensitive resistance elements TH1-TH4. Therefore, when the hot water storage capacity reaches 50l, because of the decreasing of the resistance value of TH1, and also the decreasing of the resultant resistance of the resultant resistance circuit 10, the transistor 20 is made OFF by the operating amplifier 16, and the burner 6 is stopped through the control unit 21.

Title: Magnetic encoder
Inventor: SHIMOMURA TETSUO
IPC: G01R33/02
Filed: 1989-06-29
Abstract: PURPOSE:To make it possible to detect the rotation and displacement of a target magnetized with fine intervals even when the interval between the target and a pickup is separated about 2 to 3mm by using a crystalline and soft magnetic fiber-like substance mainly consisting of Fe for a magnetic core. CONSTITUTION:For instance, a ferrite-made magnetizing pitch having 40mm diameter forms a drum 1 of about 1.25mm. An urethane coated wire having about 80mum diameter is utilized as a pickup coil and a single connection metallic fiber consisting of Fe-Si alloy and having 80mum diameter and 40mm length is used as the magnetic core to form a coil of 1000 turns. The pickup coil 2 is arranged with about 2mm interval from the drum to be inspected. A signal induced by rotating the target is converted from current into voltage by a converter 3, amplified by an amplifier 4, shaped at its waveform and outputted at a TTL level. Consequently, detection can be attained even at a high temperature (about 300 deg.C) and highly accurate detection can also be attained.

Title: Device for detecting fluid mixing ratio of gasoline, alcohol or the like
Inventor: MIYATA SHIGERU
IPC: G01N33/32
Filed: 1987-07-03
Abstract: PURPOSE:To make temp. compensation of a light receiving element with a relatively simple structure without using a temp. sensor by using a light receiving element for compensation to a device for detecting a fluid mixing ratio having a light transparent body disposed with a light emitting element and the light receiving element at both ends. CONSTITUTION:The output from the light receiving element 36 for compensation is applied through a 1st operational amplifier 270 to a negative terminal of a 2nd operational amplifier 271 and the energization current to the light receiving element 35 increases so as to compensate a decrease in the light emission efficiency of the light emitting element 35 with an increase in the ambient temp. Since the refractive index of the fluid to be measured increases simultaneously, the output of the light receiving element 35 tends to increase; however, the output voltage from the 2nd operational amplifier 271 is gradually decreased by the drop of the output voltage of the light emitting element and, therefore, the quantity of the light emitted by the light receiving element 35 declines. The quantity of the light received by the light receiving element 55 is thus gradually decreased and the output thereof is returned to the normal, by which the compensation of the temp. is executed.
