Filed: 1994-02-08
Abstract: PURPOSE: To provide excellent frequency agility and low phase noise by using the three pieces of digitally programmable frequency dividers provided with successive phase locked loops. CONSTITUTION: A frequency multiplication circuit 14 multiplies the source frequency of the output of a reference oscillator 12 and generates reference frequencies F1-F3. The reference F1 is shifted by a first programmable divider 16 and the frequency F1' is fed back through a first phase detector 22, a video amplifier 24, a first voltage controlled oscillator 30, a first mixer 32, a first loop filter 34, a first loop amplifier 36 and a second programmable division circuit 38 to the detector 22. The mixer 32 mixes the reference F2 and the output of the oscillator 30.  The output of a first phase locked loop 20 reaches a second phase locked loop 40 through a third programmable division circuit 39, a second feedback circuit is formed similarly to the loop 20 and the output of a second voltage controlled oscillator 50 is outputted as the output frequency signals F0 of this frequency synthesizer 10.

Inventor: FUNAHASHI ISAO
IPC: C02F1/66
Filed: 1989-01-24
Abstract: PURPOSE:To successively improve drinking water, so that it can have a predetermined Langelier index by dissolving carbon dioxide in an untreated water to produce a free carbon dioxide contg. water at a predetermined concn. and supplying thereto a specific amt. of a nearly satd. aq. soln. of slaked lime. CONSTITUTION:Carbon dioxide is introduced from a carbon dioxide bottle 7 into a carbon dioxide dissolver 5 by an injector 8 in a controlled amt. so as to produce a predetermined amt. of the water contg. free carbon dioxide. The concn. of the free carbon dioxide is detected indirectly from the pH or amt. of untreated water and the amt. of the carbon dioxide fed. The resulting free carbon dioxide contg. water is sent into a tank 13, into which a nearly satd. aq. soln. of the slaked lime is introduced from a slaked lime dissolver 1 to produce the drinking water having a predetermined Langelier index. Since this method can improve the Langelier index and control the corrosive effect of the drinking water, it is extremely effective in preventing the production of rusty water.

Filed: 1988-01-26
Abstract: PURPOSE:To prevent a learner from erroneously learning KANJI (Chinese character) expressions by displaying whether an inputted reading and the reading of a retrieved KANJI expression coincide with each other or not. CONSTITUTION:Since headword retrieval is executed by a learner who knows a reading but does not know its KANJI expression, he may mistake a displayed KANJI expression for the expression corresponding to the inputted reading if this KANJI expression which does not coincide with the inputted reading but approximates it is displayed by retrieval. This system displays whether the inputted reading and the reading of the retrieved KANJI expression coincide with each other or not. That is, it is displayed whether the reading of the retrieved KANJI expression or the reading of the KANJI expression read out in accordance with the operation of a feed key and the inputted reading coincide with each other or not, and the learner can intuitively recognize the disaccord of the reading by this display.

Title: Air blow-off device for vehicles
Inventor: TAKAHASHI YUTAKA
IPC: B60H1/00
Filed: 1978-02-13
Abstract: PURPOSE:To permit fluid to be blown off over the whole area of a vehicle, by fitting a fluid blow-off element at the ceiling of vehicles so that a blow-off port may  be formed. CONSTITUTION:A left and right side of a fluid blow-off element 1 are covered by covers 15, 16, and adjusting ports 17, 18 whose openings are made in the covers 15 and 16 respectively, are connected to adjusting rooms 13 and 14. Side walls 8 and 9 are mounted at a down stream side of a nozzle, and almost the whole is made in a circular arc so that a single opening can be formed. With the device constituted above, the flow, which comes in from a nozzle 7, is throttled suddenly at the outlet of the nozzle 7, wherewith a vena contracta is produced and the fluid in control rooms 13 and 14 is sucked into the flow. Thus, fluid flow is one-sided due to the relation between opening areas of the control ports 17, 18 and a set-back Se. For instance, a flow c will not become sufficient enough to produce the suction- in according to the limitation degree of the opening when the control port 18 is limited to be opened. Simultaneously, the pressure in the control room 14 decreases, and the flow is one-sided in the right. A smooth air swing can thus be achieved.
