Title: Radioactive waste liquid reconcentrator
Inventor: INAGUMA MASAHIKO
IPC: C02F1/04
Filed: 1994-02-28
Abstract: PURPOSE:To concentrate a waste liquid stored in a concentrated waste liquid tank, reduce the volume of it and decrease the number of required drums by installing transferring pipes (recirculating pipes) between a concentrator and the concentrated waste liquid tank. CONSTITUTION:A concentrator 40 is connected through a concentrated waste liquid outlet pipe 41 and a switch-over valve 42 to a highly conductive concentrated waste liquid tank 43 on one hand and to a washing concentrated waste liquid tank 47 on the other hand. Since the waste liquid which is drained from the inside of the concentrator 40 for the purpose of maintenance is mixed with the highly conductive concentrated waste liquid being stored in the tank 43, the waste liquid in it is diluted and its concentration becomes less than a prescribed value. The waste liquid of such a condition is returned through a recirculating pipe 51 to the concentrator 40 again by a pump 44, where the waste liquid is treated to condense it. As this can reduce the volume by concentrating the waste liquid to a prescribed higher concentration, the number of required drums is decreased in the treatment for solidification. Likewise, the washing concentrated waste liquid in the tank 47 can also be reconcentrated by returning it through the recirculating pipe 51 to the concentrator 40 with a pump 48.

Abstract: PROBLEM TO BE SOLVED: To provide an automatic power control circuit easy to be constituted and capable of performing a stable operation. SOLUTION: This circuit has a pre-amplifier 1, a power amplifier stage 2 and a final power amplifier stage 3 for performing an amplification operation by supplying power from a battery power source and connected to each other in series. The voltage corresponding to the outputted power of the final power amplification stage 3 is detected in a transmission power detection circuit 4, the detected voltage is compared with preliminarily fixed reference voltage in a first comparison circuit 10 to output the different voltage. A first control circuit 9 adjusts the battery power source based on this output to supply the power source as the power source voltage of the power amplification stage 2. The voltage to which a reference power source is shifted in a voltage shift circuit 6 is compared with the voltage outputted from the first control circuit 9 in a second comparison circuit 7.  Based on the compared result, a second control circuit 8 controls at least one of the first comparison circuit 10 and the first control circuit 9 to control the voltage outputted from the first control circuit 9.

Filed: 1987-02-10
Abstract: PURPOSE:To improve the design of a character and to shorten a compression operational processing time, by synthesizing an upper half script character pattern and a lower half script character pattern to store a pattern. CONSTITUTION:24 longitudinal dots are expressed by 3-bite data. In the case of a super-script, fundamental data 1 are set to printing data 1 as they are and the lower half of fundamental data 2 is converted to non-printing dots to be set to printing data 2 and fundamental data 3 are entirely converted to non-printing dots to be used as printing data 3 to obtain the character pattern of the super-script. The foregoing has been explained in longitudinal 24Xlateral 16 dots but practice is also possible in the number of other dots. As mentioned above, by storing the character pattern of the super-script in the upper half and storing the character pattern of a sub-script in the lower half, a character design becomes well as compared with a conventional system and a processing speed becomes faster.

Title: Rotary heat exchanger
Inventor: HASEGAWA KEIJI
IPC: F28D15/00
Filed: 1980-03-12
Abstract: PURPOSE: To improve the heat transfer performance and the fan performance of a rotary heat exchanger for recovering the heat of the waste gas in a factory by arranging in space heat transfer tubes to form passages between the tube groups when the tubes are arranged on a rotary tube plate and preventing the concurrent rotation of the fluid and the tubes.  
     CONSTITUTION: When heat transfer tubes 1 are arranged on a rotating tube plate 2, they are not densely arranged, but arranged radially at every other rows to radially form passages 10. Since the fluid flowing in the casing 3 to make contact with the heat transfer tube groups 1 so as to thermally exchange flows through the passages 10 formed between the tubes 1 with such a construction, it can reduce the concurrent rotation of the fluid and the tube groups 1. Accordingly, since the fluid accelerates its relative velocity, the heat transfer performance and the fan performance can be improved.

Title: Level shift circuit
Inventor: HASHIMOTO YOSHIHARU
IPC: H03K17/16
Filed: 1991-02-25
Abstract: PURPOSE:To reduce the through-current and to improve the response speed by adding an N-channel MOSFET and a differentiating circuit to an input terminal and an output terminal of an inverter respectively. CONSTITUTION:An N-channel MOSFET Q5 and a differentiating circuit A are added to an input terminal of an inverter INV 1 of a conventional circuit and an N-channel MOSFET Q6 and a differentiating circuit B are added to an output terminal. FETs Q5, Q6 are turned on in the normal state. When a level of a signal D changes from H to L, a FET Q3 is turned from OFF to ON, a potential at a point (c) of the FET Q5 changes from VDD2 into (VDD2-VDD1) by the differentiating circuit A and the FET Q5 is turned off and no through-current is caused. A potential at a point (a) is equal to a voltage VSS2 immediately, a FET Q1 is turned off and the FET Q5 is gradually turned on. In this case, a potential at a point (d) is changed from VDD2 into (VDD2+ VDD1), but since the FET Q6 keeps the ON state, the level at the point (b) is equal to the voltage VDD2 and the FET Q6 is made stable. Since the processing of the circuit is similarly when the level of the signal D changes from L to H, no through-current is caused.
