Abstract: PROBLEM TO BE SOLVED: To avoid the feed of microbes into a mixer water tank and stabilize the operation by arranging a replenishing water line having a sterilizing means in which replenishing water is converted into pure water or strong acidic water, then supplied to the mixer water tank. SOLUTION: A sterilizing means 24 in which replenishing water is converted into pure water or strong acidic water, then supplied to a mixer water tank 22 is arranged in a replenishing water line 23 through which the replenishing water is supplied to the mixer water tank 22 and water balance is held. As the sterilizing means 24, an ion exchange water treating device is suitable, and when the replenishing water is changed into pure water, the mixing bed of a cation exchanger and an anion exchanger is used as an ion exchanger. When the replenishing water in converted into strong acidic water, only the cation exchanger is used as the ion exchanger.  The feed of microbes into the mixer water tank 22 from the replenishing water line 23 in prevented, and at the same time, salts which become a metabolism of the microbe are removed, and thereby, the propagation of the microbe in the mixer water tank 22 is prevented.

Filed: 1987-05-08
Abstract: PURPOSE:To measure the threshold voltage of a memory element by providing a voltage impressing means which impresses a voltage to the gate of the mem ory element when measuring the threshold voltage on the enhancement side, but impresses the voltage to the source and a substrate when measuring the threshold voltage on the depression side. CONSTITUTION:Two test modes for the measurement of the threshold voltage of the memory element 11 are provided; in the mode in which the enhancement side is measured, the voltage is impressed to the gate of the memory 11, but in the depression side measurement mode, the voltage is impressed to the source of the element 11 and the substrate.

Title: Clock generation circuit
Inventor: IIJIMA TAKAYUKI
IPC: H04N19/85
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To obtain a clock generation circuit generating a clock without causing any jitter. SOLUTION: A counter 1 presets reference time information received from an external device and counts a time based on a clock signal obtained by feeding back an output signal. A subtractor 2 subtracts the numeral of count from reference time information and an adder 3 an error of a clock signal at a preceding time to this time and the subtracted result. A latch 4 stores the sum result as a new error, a D/A converter 5 converts the error into an analog signal and the output after D/A conversion controls an output of the clock signal outputted from a voltage controlled oscillator 6. Since the clock signal output is controlled to take synchronization between the reference time information and the generated clock, the given error voltage is kept constant thereby eliminating jitter.

Filed: 1984-06-05
Abstract: PURPOSE:To lighten the whole of a marine propeller and facilitate the handling by diminishing the number of gears constituting advance/retreat switch mechanism smaller, and also by making a power diverging means smaller. CONSTITUTION:The respective components for drive systems are made smaller by diverging the output of the engine into a drive system comprising a first drive shaft 13 and a first propeller shaft 17 and another drive system comprising a second drive shaft 14 and a second propeller shaft 18. This constitution makes the projected shape of the casing 11 containing those components in the cruising direction smaller. As a result, the propelling efficiency is improved. And the whole weight of the external equipment of a ship is lightened and the handling facilitation is iomproved by diminishing the number of gears constituting an advance/retreat switch mechanism to two pieces, a first gear 28 and a second gear 29. And by providing the second gear 29 alone in the space between the first drive shaft 13 and the second drive shaft 14, the distance between the two drive shafts 13 and 14 becomes smaller and as a result, a first transmission gear 15 and a second transmission gear 16 also become smaller. Thus, the weight of the whole of external equipment of the ship is lightened.

Title: Paper discharging device

IPC: B65H29/70
Filed: 1982-07-02
Abstract: PURPOSE:To correct every possible curl in a sheet of copying paper without any damage and make the paper tough enough to resist buckling, by causing the diameter of an external flange to be larger than that of an inner flange of a delivery roller available for a copying machine, and yet giving the paper a weak force at the inner side while giving it a strong force at the outer side in contrast. CONSTITUTION:Sheets of A3 format copying paper 11a are delivered by three delivery rollers 13-15 and idler rollers 35 connected to these delivery rollers, and both ends of about 20mm. in the widthwise direction of the paper 11a are situated outward from each of delivery rollers 13 and 15 at the outer side. For this reason, both these ends in the widthwise direction of the paper 11a receive relatively large force in a reverse direction against the sense of curling through large flanges 29 and 30, and since flanges 23-26 are all small in size, their force to be given to the paper 11a is relatively weak. With this, even if the paper 11a is such a thin type as tracing paper, all possible curls are fully correctable without any damage, besides making every sheet tough enough to resist buckling, and thereby all sheets of paper can be discharged properly in regular sequence. Likewise, in case of delivering sheets of A1 format paper 11 are carried out by the delivery rollers 13-15 in the same manner, not to mention the curl correction.

Abstract: PURPOSE:To enable light irradiation with uniform intensity by splitting parallel light which is incident on the incidence surface of a concentric prism lens at right angles into plural parallel light beams by plural annular prisms, and superposing those parallel light beams. CONSTITUTION:The plural annular prisms l1 and l2 have the concentric prism lens PL provided concentrically and a projection lens Lp. When the parallel light B which has an irregular intensity distribution is incident on the incidence surface of the concentric prism lens PL at right angles, the parallel light beam B is split by the concentric prism lens PL into three parallel beams in total. Those parallel beams are put one over another on a beam superposition surface to obtain irradiation light having a uniform intensity distribution, so the irradiation light having the uniform intensity distribution is projected on an irradiated surface through the projection lens LP. Consequently, the light irradiation with uniform intensity is performed.
