Title: Purification of avermectin
Inventor: KINOSHITA ITARU
IPC: C07H17/08
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To purify avermectin useful as e.g. a parasite-controlling agent for livestock without the need of using chromatography, by extracting an avermectin-contg. material with a water-miscible solvent followed by concentrating the liquid extract and then adding a water-miscible solvent again and a salt to the concentrate and collecting the resultant insolubles. SOLUTION: An avermectin-contg. material such as insolubles in a fermented culture liquor of avermectin is brought into contact with a water-miscible solvent (e.g. methanol) to extract avermectin under the concentration of the solvent at 50-70wt.%, the resultant liquid extract is concentrated, and then a water- miscible solvent again and a salt (e.g. sodium chloride) are added to the concentrate and the resultant insolubles are collected and then brought into contact with a water-miscible solvent, and the resultant solution freed from residual insolubles is concentrated and the precipitate formed is collected, thus efficiently, easily and inexpensively purifying the objective avermectin B1a useful as a raw material for ivermectin as a parasite-controlling agent, or as a parasite- controlling agent for livestock without the need of using industrially complicated chromatography.

Title: Semiconductor memory
Inventor: HIRATA MASAYOSHI
IPC: G11C17/00
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To cancel a holding of erroneous data by holding the output data of a main sense amplifier by means of a data holding means by utilizing the timing that a dummy sense amplifier outputs the data of a dummy memory cell. SOLUTION: In a dummy sense amplifier 52, since the threshold level of an inverter to which the output signal of a differential amplifier stage is inputted is set to be 4V, the output signal DS of the amplifier 52 falls slightly layer than the output signal of a main sense amplifier 51. The output signal DS of the amplifier 52 is inputted to a fall signal delay circuit 3, outputted as a signal DLS and fallen to L, after a delay time in synchronism with the fall signal of the signal DS. The output signal DSi of the amplifier 51 is held by a data holding circuit 4, by means of the fall signal and outputted as a signal Di. Since the signal Di is held at almost the same time as the determination of the output of the sense amplifier, it is automatically set as the optimum value, without considering the fluctuations in a power source potential.

Title: Filter clogging detecting device for heater
Inventor: MORISHIMA MASAYUKI
IPC: F23N5/24
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent the faulty detection of clogging by a method wherein the indication of clogging of a filter is prohibited for a given period of time when the amount of combustion of a burner is reduced by an amount more than a given value, in a heater, in which the clogging of the filter is indicated when a combustion chamber temperature is raised by the clogging of the filter and the temperature has arrived at a value higher than a predetermined temperature. SOLUTION: When combustion operation is started, a filter sign (indication of filter clogging) is decided whether it is delayed or not (step 30). When the filter sign is not being delayed, the amount of combustion is checked whether the same amount was changed from strong to weak (step 31). When the amount of combustion is not changed, the temperature of a combustion chamber is read by an overheat preventing thermistor (step 34). When the read temperature is higher than a predetermined value, a filter sign treatment is carried out (step 35). When it is judged that the amount of combustion has been changed from strong to weak (step 31), the amount of combustion is checked (step 32) and when it is reduced by an amount more than a given amount, the filter sign is delayed and, simultaneously, a timer for delaying the filter sign for a given period of time is set (step 33).

Title: Manufacture of single-tab semiconductor device
Inventor: PIITAA JIEI ZUDEBERU
IPC: H01L21/331
Filed: 1988-06-23
Abstract: PURPOSE: To reduce the size of a single-tab semiconductor device as much as possible without sacrificing the performance of the device by forming first and second non-overlapping apertures above a semiconductor island (tab), third openings on the outside of the island in the lateral direction, and fourth apertures which surround the three first apertures in the lateral direction on the outside of the island. CONSTITUTION: A structure is coated with a mask 30 having apertures 40, 41, 43, and 43. The mask 30 is a master mask and has the apertures which decide the critical lateral size of a device and position all contacts of the device. Layers 26 and 28 below the apertures 40-43 are partially removed by using the mask 30 so that the part below a layer 24 can be exposed. Then a first block-out mask 32 having a boundary 32A is deposited. After the lower section 22A of a polycrystalline layer 22 is exposed, the mask 32 is removed. After the mask 32 is removed, the remaining part of the layer 26 and the exposed part 22A of the layer 22 are converted into dielectric materials (for example, silicon dioxide).  When the remaining part of the layer 26 is converted, an oxide region 35 is formed and, when the exposed part 22A of the layer 22 is converted, an oxide region 34 which is smoothly joined with the region 35 is formed.

Title: Electrolytic cell
Inventor: YOKOTA KENICHI
IPC: C25B9/19
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To suppress production of ozone and to sufficiently maintain the sterilizing effect of a strong acid water by forming a two-layer structure of a platinum plating layer and an iridium plating layer on the surface of a titanium electrode base body. SOLUTION: The electrode used for electrolysis of water has such structure that consists of a titanium base body 10, a platinum plating layer 11 on the titanium surface, and further an iridium plating layer 12 on the surface of the platinum layer. Instead of iridium for the layer 12, palladium or rhodium can be used. When only a platinum plating layer is formed as a conventional method, toxic ozone is produced by the catalytic effect of the platinum. By covering the surface of the platinum with a noble metal such as iridium, the catalytic effect of platinum can be suppressed to avoid production of ozone. The strong acid water produced on the anode contains a large amt. of hypochlorous acid by the catalytic effect of iridium, which has a strong sterilizing effect and is harmless.
