Title: Range finder
Inventor: UEDA CHUICHI
IPC: G01B11/00
Filed: 1997-03-15
Abstract: PROBLEM TO BE SOLVED: To improve distance measurement accuracy of a range finder by measuring distance to a detected object based on the scanning angle of light before the light enters on the object. SOLUTION: Optical beam LB which is X-axially scanned using a first galvano-mirror 11 is Y-axially scanned further by a second galvano-mirror 12, and the optical beam LB is irradiated on the surface of a detected object 2. The optical beam LB which reflects on the surface of the detected object 2 is focused on a two-divided light receiving element 13 by a light receiving lens 4. Distance L from the light receiving lens 4 to the detected object 2 is calculated using rotational angle of the second galvano-mirror 12 at the moment when a light spot S is received in the intermediate point between two light receiving faces 13a and 13b of the two-divided light receiving element 13.

Title: Method of measuring residual stress of strand
Inventor: UEMATSU TADAYUKI
IPC: G01L1/00
Filed: 1978-07-07
Abstract: PURPOSE: To perform stress measurement with simple method and high fidelity by determining residual stress of strand from the obtained distortion value of the outer layer strand which has been released from a strand consisting of a plurally layered strand.  
     CONSTITUTION: On the outer layer strand 2 of a strand consisted of a plurally layered strand, scales are marked with a prescribed interval, and the layer 2 is fixed by covering its outer side by fixing material 3 which is formed of adhesive 4 and coating 5 (teflon etc.). After each layer except the layer 2 is taken out, material 3 is removed by resolving a part of the inner wires made of hard drawn copper, etc., using concentrated sulfric acid, etc., then the layer 2 is made free. Under this condition, variation of scales marked on the layer 2 is measured, and the desired residual stress of strand at the time of its manufacturing is determined with ease and high fidelity. The same result is obtained by measuring deformation using strain gauge.

Title: Descaling method of titanium material
Inventor: KITANI SHIGERU
IPC: C23G1/10
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a good surface state by subjecting a titanium material, which has an oxidized scale on the surface, as necessary after immersing in a molten alkali salt bath, to an electrolytic treatment in an electrolytic water solution and then to pickling so as not to generate a spark flaw and to remove. SOLUTION: When descaling a titanium material having an oxidized scale generated in hot working and annealing, in the case the oxidized scale has a thickness of <about 10 nm, descaling is easily done by immersing a titanium material in a nitrohydrofluoric acid pickling solution. Further, in the case the oxidized scale has a thickness of about 10-350 nm, for example, a titanium material 2 is subjected to electrolytic treatment by successively/indirectly energizing in an electrolytic water solution between a pair of positive electrodes 1-1, 1-2 and between a pair of negative electrodes 3-1, 3-2 and then pickling.  Further, in the case the oxidized scale has a thickness of >= about 350 nm, a titanium material is immersed in a molten alkali salt bath composed of NaNO3 , NaOH, etc., after the scales thickness is thinned till <= about 300 nm to >= about 30 nm to generate no spark, and is subjected to electrolytic treatment and pickling.

Title: Level converting circuit
Inventor: KAMIHIRA EIJI
IPC: G05F1/10
Filed: 1981-05-28
Abstract: PURPOSE:To detect accurately a water power level corresponding to a switching mode and to realize the level discrimination, by using a variable impedance connected to a switching element and a means having a level discrminating function. CONSTITUTION:For instance, resistances 24 and 25 of a variable impedance circuit 8 are set at 10KOMEGA and 3KOMEGA respectively. The common contact 21 of a changeover switch 20 in the circuit 8 has the conduction to an individual contact 23. Under such conditions, the common contact 4 of a switching element 3 has the conductiln to an individual contact 11. As a result, the voltage V19 at a joint 19 is higher than the discrminating level Vl of the circuit 8, and accordingly, the contact 21 has the conduction to a contact 22. Thus the voltage of the joint 19 increases, and a microcomputer 2 discriminates the voltage at an input terminal 7 as the logical value 1. When the contact 4 of the element 3 has the conduction to an individual contact 10, the voltage 19 is set at a level obtained by dividing the voltage of a power supply 18 which is equivalent to the voltage drop of a car body. The voltage V19 is lower than the level Vl, and the contact 21 has the conduction to the contact 23. As a result, the voltage V19 is reduced. The computer 2 discriminates this voltage as the logical value 0.

IPC: C08B37/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To recover dispersion, precipitation and the like of a cellulose when water is added to the dried cellulose by concentrating of aqueous suspended liquid containing a fine fibrous cellulose until the cellulose content becomes not less than a specific value and then freeze-drying of the concentrated cellulose. SOLUTION: An aqueous suspended liquid containing a fine fibrous cellulose such as a bacteria cellulose or the like is concentrated by means of a method selected from a filter press, a centrifugal separation, a filtration under reduced pressure and the like until a cellulose concentration becomes not less than 4 wt.%, preferably 10-75 wt.%. A predetermined amount of a hydrophilic solvent or a water soluble material such as a glycerin, a dimethyl sulfoxide or the like, if necessary, is added to the concentrated liquid, which is then freeze-dried to produce a dried cellulose having a moisture activity of not more than 0.9. It is preferable that the bacteria cellulose to be concentrated can dissociate.  Such bacteria cellulose is obtained by treating an aqueous liquid containing 0.01-30 wt.% of a bacteria cellulose by mechanical means such as a mixer, an ultrasonic generator or the like or by acid and/or alkali hydrolysis.

Title: Drive method for line sensor
Inventor: ISHIHARA ATSUHIKO
IPC: H04N5/353
Filed: 1995-04-07
Abstract: PURPOSE: To realize a drive method for a line sensor having an electronic shutter function in which a charge storage time of the line sensor is varied optionally for a one line period without losing the image quality. CONSTITUTION: A timing when a register transfer pulse is outputted is controlled not to output a charge from a transfer register 12 at the rise and fall of an electronic shutter pulse varying a charge storage time of a light receiving section 10 of a line sensor. For example, when the charge storage time by the electronic shutter pulse is within a prescribed time, the register transfer pulse is continuously outputted just after the input of a read gate pulse, and when the charge storage time is a prescribed time or over, the register transfer pulse is continuously outputted from a nearly midpoint between the read gate pulses. Thus, the charge storage time of the line sensor is varied arbitrarily for a one-line period without causing a streak image.

Title: Film feeder
Inventor: SHIRAI MASASHIGE
IPC: G03B21/11
Filed: 1981-05-29
Abstract: PURPOSE:To surely perform feeding of a film, by moving a feeding roller with the revolution of a motor so that the roller can be approached to a cartridge and disconnected from it. CONSTITUTION:When a motor 20 rotates, a feeding roller and a planet gear 25 tend to turn to the same direction. But since the rotation of a brake gear 26 is blocked with a friction member (not shown) held with a spring 29, the planet gear turns around the circumference of the brake gear. Thus, when a shaking plate 22 fixing a motor is turned and moved to a prescribed position, a feeding roller 9 fixed to a motor rotating shaft 21 reaches a position in contact with a leader tape in a cartridge 8. Through the pressing of the feeding roller on the leader tape, the brake gear turns against the friction force, the feeding roller 9 turns and the leader tape is fed. When the motor is reversed through the  detection of tape winding, the shaking plate and the feeding roller return to the original position.

Therefore, the low gamma property of the protective layer is melted away, and the generation of abnormal discharge on the cell layer is prevented.
