IPC: H01M2/16
Filed: 1987-02-24
Abstract: PURPOSE:To obtain a flat type cell with excellent heat-resistance and process- stability by fixing the diameter of the glass-system fiber of a separator made of a blended fabric of a cellulose and glass-system fiber whose melting point is higher than that of an unwoven cloth made of polypropylene. CONSTITUTION:A negative electrode 3 and a positive electrode-block mixture 4 are placed, through a separator, between the positive electrode-terminal plate 1 and the negative electrode-terminal plate 2 of a flat type lithum cell so as to face each other, and a space between the terminal plates 1 and 2 is sealed by a sealing member 6. This separator 5 is made of the blended fabric of cellulose and glass-system fiber and the diameter of the fiber of a glass-system as its blended fabric is set to 0.5-40mu. The separator is made of the blended fabric of a cellulose and glass-system fiber having high tension and flexibility so as to improve stability of a cell assembling-process and prevent the separator from melting when a card-laminate is heated.

Title: Tidal electric generator
Inventor: KOBAYASHI SHINICHI
IPC: F03B7/00
Filed: 1978-04-10
Abstract: PURPOSE: To efficiently increase the flowing velocity of tide and obtain a high output by a relatively small water wheel, by providing multistage flow converging pipes, each of which has a major-diameter inlet port and a minor-diameter outlet port.  
     CONSTITUTION: A float 1 is anchored so that the axis of the flow converging pipes 2, 3 almost coincides with the direction of the tide. The seawater is guided on the oblique face of the front bottom of the float 1 so that the seawater is conducted into the first-stage flow converging pipe 2. Because the diameter of the outlet port of the pipe 2 is smaller than that of its inlet port, the flowing velocity of the seawater is increased and its pressure is decreased according to Bernoulli's theorem. A large amount of seawater is thus brought to the second-stage flow converging pipe 3. The flowing velocity of the seat seawater is increased further by the pipe 3 to rotate the water wheel installed in the pipe 3 to produce electric power by a dynamo 5.

Title: Device for lighting discharge lamp
Inventor: SATOMI AKIRA
IPC: H05B41/282
Filed: 1988-02-24
Abstract: PURPOSE:To effectively supply power without an unstable arc in a lighting device for alternately supplying high frequency power and DC current to a high pressure discharge lamp by specifying the frequencies of the high frequency power and DC power. CONSTITUTION:A high frequency power with a frequency fHF and a chopper DC current with a frequency fDC are alternately supplied to a high pressure discharge lamp la through a serial circuit of a capacitor C1 parallel to the lamp la, an inductance element L1 serial to the capacitor C1, and a transistor circuit Q1, respectively. A relation of fDC>fHC>fLC (where fLC is a resonance frequency) is maintained. A lighting device having stable arc due to high fre quency components and having high efficiency is obtained, and the mode of an oscillation current turns to be a delay phase mode even at the time of DC operation, so stress in an switching element is reduced.

Title: Lens grinding work device
Inventor: SHIBATA RYOJI
IPC: B24B27/00
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To reduce a workable minimum diameter to avoid interference between the lens rotating shaft side and a grinding wheel, and easily control its minimum diameter by providing a work control means which controls rough work and finishing work by work data and controls chamfering work on the basis of a chamfering work position and a corrective locus. SOLUTION: A control part obtains a lens shape chamfering locus by finding a chamfering work point P of an edge over the whole circumference on the basis of input indication of edge position information obtained by measurement, a lens edge position information and a chamfering quantity, and performs a corrective calculation to find chamfering work data to avoid interference between a chuck shaft and a grinding wheel on the basis of this locus, and obtains Xn being a reference corrective locus. Then, a value of X (a center distance between the lens rotating shaft and a grinding wheel rotary shaft) in a position using the lens rotating shaft as a reference position is found from this locus Xn.  In this way, since a moving distance of a chamfering grinding wheel in the Z axis direction (the optical axis direction) is corrected by precedently deciding the value of X, chamfering work can be performed even on an edge corresponding to a minimum locus by a grinding wheel diameter large place.
