Abstract: PROBLEM TO BE SOLVED: To produce boiler compounds excellent in scale removing performance and capable of washing and removing a scale while executing a normal operation by using a water soluble polymer having a carboxyl group or its salt and a sulfo group or its salt in a structure and having a specified average mol.wt. and acid value as the boiler compounds. SOLUTION: The water soluble polymer has the carboxyl group or its salt and the sulfo group or its salt in the structure and has a weight-average mol.wt. of 100000-1000000 and >=500mgKOH/g acid value. The water soluble polymer has an unsatd. carboxylic acid or its salt and an unsatd. sulfonic acid or its salt as a constituent monomer, and its proportion is (95/5)-(50/50) preferably. The polymer forms an anionic atmosphere and incorporates a cation of a scale component and the scale is removed. The scale is removed without stopping a circulation of a cooling water when used as a scale removing agent for cooling system. It is safety since it is used near neutral.

Filed: 1984-05-26
Abstract: PURPOSE:To improve the breakdown withstand strength of an FET and the latching current value of a conductivity modulation transistor by forming the narrow irregular surface of a source region in a repeated pectinated source shape. CONSTITUTION:A source region 5 is formed repeated with a narrow recess 5 near a gate electrode and a narrow projection 52 of the width extended in reverse direction from the vicinity of the gate electrode. Since the irregular surface 51, 52 of the source shape are decided only by the patterning mask of source diffusing hole, the widths of the recess 5 and the projection 52 can be designed in several mum. As a result, the diffusing resistance of a baase body region 4 can be substantially reduced, thereby improving the breakdown withstand strength of the FET and the latching current of a conductivity modulation transistor.

Filed: 1982-06-22
Abstract: PURPOSE:To raise a processing speed by making use, as a processing liquid, of an aqueous solution containing an organic compound in each element ratio less than H/C=1.4 and O/C=0.5. CONSTITUTION:An aqueous solution containing an organic compound in each element ratio less than hydrogen / carbon=1.4 and oxygen / carbon=0.5 is used as a processing liquid. When the processing liquid containing the component of an organic compound with its concentration less than 50% in the weight ratio is used in a processing tank, while the solubility of said organic compound in water is more than 50%, it does not burn because of the presence of water, thus eliminating the fear of a fire.

Abstract: PURPOSE:To attain the low leakage current structure making no n-n connection at all by taking the interface of the first and second buried layers near mesa stripe as a specific crystalline direction. CONSTITUTION:A clad layer 2, an active layer 3 and another clad layer 4 are grown on a P-InP substrate 1. The whole surface is coated with an SiO2 film to form a mesa stripe having smooth side without a bent part at all using the SiO2 film as a mask. Next, a P-InP layer 5, an n-InP layer 6, another p-InP layer 7 and another n-InP layer 8 are buried in the sides. Next, the surface of the p-InP layer 5 is to be grown until (133) surface is formed represented by surface A, 76+ or -5 deg. with the surface (100). Later when the n-InP layer 6 is continuously grown, the surface A is also grown as if creeping up. When the growing step is terminated before reaching the topmost part of the mesa, the surface of the n-InP layer 6 on the mesa side also becomes the surface A. In such a buried structure, the periphery of the n-InP layer 6 is structured of the p-InP layer encircling the same thereby enabling the block layer structure making no n-n connection at all to be formed.

IPC: F04D27/00
Filed: 1981-07-08
Abstract: PURPOSE:To provide a fully cool feeling by ON/OFF controlling a plural of wind-speed notches of the fan motor at comparatively short and different intervals, and thereby allowing the wind-speed to vary slowly so as to give a varied wind which provides a similar feeling to natural winds. CONSTITUTION:A switch SW8 is to perform intermittent operation of a fan motor FM. If now this switch SW8 is put on under the condition that the fan motor FM operates at a high speed, a micro-computer IC3 judges the signal fed through Terminal 21 to place out a control signal at Terminal 19 on the basis of the programput in memory in the ROM. Under the command of this control signal, a triac Q1 is put ON and OFF to operate intermittently the fan motor FM at high speeds. The wind thus obtained by putting ON and OFF the high speed operation of fan motor FM is a varied one similar to natural winds, which provides a fully cool sense for a human being.

Title: Simple multiprocessor system
Inventor: ISHIBASHI FUJIO
IPC: G06F15/16
Filed: 1980-08-04
Abstract: PURPOSE:To transmit data with high quality and to perform arithmetic processing with a software by constituting a multiprocessor by connecting plural CPUs without deteriorating practically processing capacity of a CPU. CONSTITUTION:When any microprocessor CPU outputs an address of a common memory MO to a address bus in an execution cycle of an instruction, a controlling circuit 5 recognizes an address of a memory MO, requires use of the memory MO to an arbitor 6 and set the CPU to a queuing state. Further, when use of the memory MO is permitted from the arbitor 6, the common bus is made to be operatable, and after a prescribed delay time, the queuing state is released to execute the instruction. After that, where access terminates, the bus MO is made to be not operatable, and a requirement to the arbitor 6 is withdrawn. In this execution circuit, only an execution cycle of an instruction becomes sometimes a queuing state, and in a read  cycle of an instruction, a queuing state does not occur, thus a processing capacity of  the CPU is not deteriorated practically.
