Title: Apparatus for desalting sea water
Inventor: SHICHIJI HIROSHIGE
IPC: C02F1/14
Filed: 1985-06-20
Abstract: PURPOSE:To increase water making capacity, by providing a heat absorbing heat insulating film having a large number of small holes and a recirculation pipe for transferring a non-condensible fluid directly under the surface of sea water in a container. CONSTITUTION:When a container 1 is irradiated with solar rays through a transparent plate, solar heat is efficiently absorbed by the thin sea water layer on a heat absorbing heat insulating film 15 and the temp. of sea water at that part is effectively raised to generate steam in order to generate saturated steam pressure corresponding to said temp. The mixture of this steam and air passes through a suction pipe header 4 from a suction pipe 3 by the sucking action of a fan 8 to be guided to a condensing pipe group 5. Because the condensing pipe group 5 is sufficiently low in temp. as compared with the surface of the sea water layer present above the film 15, a part of steam introduced into the condensing pipe group 5 is condensed to generate fresh water which is, in turn, sent to a water storage tank by a water feed pump 10 and a water feed pipe 11.

Title: Turning angle controller for turnable excavating bucket
Inventor: KUMAZAWA KOJI
IPC: E02F9/20
Filed: 1990-05-23
Abstract: PURPOSE:To constantly maintain a turnable excavating bucket in one direction irrespective of the turning motion of an upper swinging body by turning the bucket by the same angle as that of the upper swinging body in the direction opposite to the turning direction of the upper swinging body. CONSTITUTION:The swung angle theta1 of an upper swinging body US and the swung angle theta2 of a turnable excavating bucket 5 are added to each other and the deviation  thetafrom the initial added value at a trench excavation starting position is calculated. A function generator 36 calculates a deviation feedback speed command value S21 from the deviation  theta and forms a driving signal Q2 from the calculated command value 21 and a reversely turning speed command value S22. When the upper swinging body US is swung by means of an operation lever after the bucket 5 is put in a trench 7, an arithmetic means 100 calculates the driving signal Q2 which turns the bucket 5 in the reverse direction by the turning angle of the body US and inputs the signal Q2 to a driving and controlling means 14. As a result, a bucket reversing motor 52 is rotated in the direction opposite to turned direction of the body US so as to maintain an earth discharging door in a fixed direction. Therefore, the need of operation for adjusting the direction of the bucket 5 can be eliminated.

Title: Throttle control device for internal combustion engine
Inventor: MUTO HARUFUMI
IPC: F02D9/02
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To surely prevent freezing of throttle valves. SOLUTION: If an engine started up is in a status of having potential icing (or step 103 is 'Yes'), a target throttle opening angle TAtg is varied over such a range between a first swivel angle taH and a second swivel angle taL as has no effect on the engine start-up quality in steps 110, 111 and 105. The throttle valve is thus swiveled across the target throttle opening angle TAtg so that freezing of the periphery of the throttle valve can be barred out.

Title: Diaphragm for speaker
Inventor: MURATA KOSAKU
IPC: H04R7/02
Filed: 1986-06-09
Abstract: PURPOSE:To obtain a high resonance frequency speaker diaphragm without causing deformation, division and vibration by using a formed thing made of sheets obtained by sticking a sheet made of polyamide prepreg on both sides of sheets made of polyamide prepreg. CONSTITUTION:A diaphragm 4, a voice coil bobbin 5 and a voice coil 6 comprise the diaphragm system of a speaker. The diaphragm is obtained in such a way that a three-layered sheet where the sheet made of polyimide prepreg is stuck to the both sides of the sheet made of polyamide prepreg is formed by heat press. Since the surface material has an extremely high bending regidity, the diaphragm never develops deformation, division and resonance during vibration. Since a core material provides great mechanical inner losses, there is less fluctuation in terms of a frequency characteristic. Therefore the speaker with an excellent sound pressure-frequency characteristic, an excellent distortion ratio and a phase characteristic can be obtained.

IPC: H03L7/06
Filed: 1986-06-11
Abstract: PURPOSE:To regenerate an original signal clock by applying feedback so that the difference between the number of output pulses and the number of the receiving pulses of a voltage controlled oscillator is '0' in a timing reproducing circuit used for non-synchronizing transmission in digital transmission. CONSTITUTION:A receiving pulse inputted to an input terminal 1 and the output pulse of a voltage controlled oscillator 6 are respectively counted by pulse counters 2-1 and 2-2, the result is inputted to a pulse number comparator 3 and the difference in the number of both pulses is obtained. The difference is changed to a voltage level by a digital-analog converting circuit 4, next, amplified by a feedback amplifier 5 and fed back to the voltage control oscillator 6. Thus, since the number of receiving pulses and the number of output pulses of the voltage controlled oscillator 6 are controlled so as to come to be the same number, a clock frequency can be regenerated even when the bright line component of the clock is not present at the receiving pulse.
