Title: Three-level inverter
Inventor: OKAYAMA HIDEO
IPC: H02M7/48
Filed: 1992-06-08
Abstract: PURPOSE:To shorten the time to reset a transformer by reducing the dielectric strength of a capacitor to recover energy accumulated in a snubber circuit, by enhancing the efficiency of energy recovery, and by enabling a plurality of phases to share recovery capacitors and energy recovery circuits. CONSTITUTION:Recovery capacitors 9A,9B are connected between nodes of snubber diodes 6A-6D and snubber diodes. 5A-5D connected in parallel to GTO 1A-1D of positive and negative arms and positive and negative side buses, energies extracted from these recovery capacitors 9A, 9B are recovered by energy regenerative circuits E1, E2 to DC power sources 4A, 4B divided by intermediate potential points. Rectification circuits 29A, 29B are connected between intermediate potential points 0 on the secondary side of each transformer 26A, 26B and the positive side or negative side of each DC power source 4A, 4B, so that the time to reset a transformer can be shortened.

Title: Garbage incineration method
Inventor: FUJITA KOZO
IPC: F23G5/027
Filed: 1988-07-08
Abstract: PURPOSE:To reduce the damage on a furnace wall in an unburnt substance combustion chamber and improve durability by supplying partial combustion air to the lower side of a fire grate and carbon combustion air to the bottom of an unburnt substance combustion furnace respectively, and increasing/decreasing the quantity of both the partial combustion air and the carbon combustion air. CONSTITUTION:When a waste A is thrown into a partial combustion chamber 13 of a primary combustion furnace 1, air is supplied from an air supply port 16, and the waste A is ignited by an ignition burner 25, unburnt substances, such as carbon drop from a fire grate 12 consecutively into an unburnt substance combustion chamber 14 as the partial combustion advances. When the temperature in a combustible gas outlet 4 rises gradually, in keeping with the progress in the partial combustion, a flow rate control valve 24 for an air supply pipe 18 is opened by way of a control unit 20 so as to supply air to the bottom of the unburnt substance combustion chamber 14. Therefore, an unburnt substance B in the combustion chamber 14 starts carbon combustion. When the temperature is increased to a certain degree inside the chamber 14, the flow rate control valve is closed so as to inhibit the carbon combustion of the unburnt substances. It is, therefore, possible to prevent the generation of clinkers inside the unburnt substance combustion chamber and improve durability as well.

Title: Data input device
Inventor: KUROSAKI MASAKANE
IPC: H03J5/02
Filed: 1983-09-17
Abstract: PURPOSE:To input a data with the same number of times as the number of digits of the data desired to be inputted by discriminating the number of digits of the data inputted depending on the content of the most significant digit. CONSTITUTION:When one of key switches KS0-KS9 is depressed and the count value of a binary counter 6 reaches ''1'', a coincidence (a) signal is outputted from a coincidence detecting circuit 11, a latch circuit 15 is set, and a data representing a numeral 4 stored in a 4-bit register 18 is outputted selectively. Thus, the number of digits of the data generated through the operation of a ten-key 1 is 4-digit, then a coincidence signal (c) is outputted from a coincidence detecting circuit 20. On the other hand, when a numeral other than ''1'' is inputted by the first depressing operation, the coincidence signal (a) is not outputted and the data respresenting the numeral 3 stored in a register 17 is outputted. Thus, when 3-digit is inputted in this case, the coincidence signal (c) is outputted.

Title: Photometric device
Inventor: MINEKANE TOMIJI
IPC: G01N21/27
Filed: 1982-09-30
Abstract: PURPOSE:To improve the measurement precision of a device which measures absorbancy of transmitted light of a cell by a detector while holding the optical path length invariably constant, by storing the quantities of light during crossing over an optical path corresponding to where light is transmitted, and extracting the quantity of light when the light is transmitted at a specific position. CONSTITUTION:The output of a logarithmic amplifier 9 which converts and amplifies the detected light-quantity voltage of the detector 8 has large absorbancy variation at the time of a cylindrical tube wall, so data from when the tube wall part starts crossing the photometric optical path 5 until the wall part finishes crossing the optical path are collected sequentially, and data on the center part is regarded as absorbancy data when the center of a cell 1a is aligned to the photometric optical path axis. A CPU11 passes a program to a data collection part 31 to read converted values out of an A/D converter 10 at constant intervals of time, stores them in a data storage part 33 in time series at a frequency of crossing, and passes the program to a data extraction part 32. Then, data in a group are compared successively from terminal data to find absorbancy data on the center of the cell 1a from the difference, thereby obtaining the absorbancy data with the constant photometric optical path length.

Title: Insulated transformer for series power distribution
Inventor: TOKUNO MASATOSHI
IPC: H01F30/00
Filed: 1981-10-29
Abstract: PURPOSE:To securely suppress a voltage generated when the secondary side becomes open by providing a through-hole on a rolled iron core in such a direction as crossing the winding axis and by selecting a hole diameter within a specified range. CONSTITUTION:An annular rolled core 6 is wound respectively by a first toroidal coil 7 and secondary toroidal coil 8 through an insulating layer 6'. This core 6 is also provided with a through hole 9 extending in the direction crossing the axial direction of said coil 6. When the size of core 6 in the axial direction is considered as A and a hole diameter as E, a through-hole 9 is formed in such a way as satisfying the relation, 0.05<E/A<=0.3. A drop rate of peak value of a voltage generated when the secondary side of transformer is open becomes larger as E/A comes closer to 1.0. However, E/A as becomes large, transformer characteristic under the rated load deteriorates. Therefore, E/A must be 0.3 or less. Moreover, if E/A becomes smaller than 0.05, reduction effect of peack voltage is sequentially lowered. Accordingly, E/A is preferably be larger than 0.05.

Abstract: PURPOSE:To proliferate suspensible animal cells in high efficiency, by controlling the partial pressure of dissolved oxygen in the culture liquid until the growth of the suspensible animal cell reaches the middle stage of the logarithmic growth. CONSTITUTION:Suspensible animal cells such as lymphoblastoid cells, myeloma cells, etc. are suspended in a nutrient medium, and cultured by rotational culture, spin culture, stirring culture, etc. In the above process, the partial pressure of the dissolved oxygen in the culture liquid is maintained at 0.01-0.05atm until the growth of the cells reaches the middle stage of the logarithmic growth by controlling the rate of stirring of the culture tank, inner pressure of the tank or the partial pressure of oxygen in air introduced into the tank. After the middle stage, the culture is continued by supplying oxygen to the tank thereby keeping the partial oxygen pressure to >=0.01atm. Good proliferation of the cell can be achieved by this process.

A microwave power inputted from a muoscillator is amplified in the cavity resonator 122 via a wave tube 121, and hydrogen gas or hydrogen/argon mixed gas introduced from a gas introduction pipe 130 to the bell jar 125 forms microwave plasma. However, since the reflection of the microwave is quickly increased after discharge, an angle theta of rotation in a polarizing direction is adjusted first so as to reduce the reflection power of a power monitor assembled in a mu stereographic circuit, thence, a variable cavity resonator length plunger 123 and a cylindrical plane sliding diaphragm 124 are adjusted.
