Title: Method for refreshing pickling bath for band stainless steel
Inventor: NAGAYA TOSHIMITSU
IPC: C23G1/08
Filed: 1987-12-23
Abstract: PURPOSE:To improve the pickling capacity and to increase the consumption of hydrofluoric acid by bringing air into contact with the pickling soln. for band stainless steel contg. hydrofluoric acid on the outside of a pickling bath to oxidize Fe<2+> to Fe<3+>, and then returning the soln. to the pickling bath. CONSTITUTION:The pickling soln. in the pickling bath 11 is sucked from a suction port 9, introduced into a tank 3 through a lifting pipe 2, and showered in the tank 3. At this time, air is preferably forced into the tank 3 by a blower 4. The pickling soln. accumulated on the bottom of the tank 3 is returned to the pickling bath 11 through a reflux pipe 6. The pickling soln. is preferably circulated at 4-20kg/cm<2> pressure to appropriately spray the soln. in the tank 3. Since air is not discharged in the bath in this method, the sludge on the bath bottom is not rolled up even when the circulation amt. of the bath is remarkably increased to increase the oxidation capacity, and hence the product is not contaminated.
Patent JP-H01169128-A (JP)
Title: Coupling
Inventor: NIIKURA YASUHIRO
IPC: F16D35/00
Filed: 1987-12-23
Abstract: PURPOSE:To increase transmitted torque according to the increase in the rotation difference without causing tight corner braking by giving a preliminary pressing force between a drive plate and a driven plate and at the same time sealing oil within a housing. CONSTITUTION:When a rotation difference occurs between input and output shafts, a drive plate 18 rotates relative to a driven plate 19. In this case, a small torque is transmitted from the input shaft 11 to the output shaft 17 caused by a small preliminary pressing force (preload) given at the time of assembly by means of the deflection of a dish plate 24. When the difference between the input and output rotations temporarily increases, heat on the friction surfaces of plates 18, 19 increases. Due to the heat generated, oil 25, 26 in a housing thermally expands to increase the press contact force between the plates 18, 19. As a result, a large torque can be transmitted from the input shaft 11 to the output shaft 17.

Title: Method and device for image formation
Inventor: TODA YUKARI
IPC: G06T1/00
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To more effectively utilize a direction judgement function and to perform the respective kinds of the appropriate layout processings of plural originals by setting the original direction judgement allowable time of a first original longer than the judgement allowable time of the other input original direction. SOLUTION: Image data after shading are thinned and fetched to a CPU/ memory part 313, a character area is segmented in an area separation part 314 and the direction of the original is recognized in a character recognition/ direction discrimination part 315. By a timer, the CPU 313 is interrupted when the limit time comes so as to prevent a direction judgement processing from becoming the bottleneck of a system. In the case of a 4-in-1 processing, in the timing chart 101 of a CCD for reading the originals 1, 2,..., the timing chart 102 of direction judgement and the timing chart 103 of print-out, the direction judgement is required to output a result at the point (triangle mark) of time of interruption from the timer.  Thus, the direction judgement time of the most important first original is taken longer and an appropriate print-out result is more accurately obtained without being delayed.

Title: Paper sheet processor
Inventor: SATO MITSUYOSHI
IPC: B65H3/06
Filed: 1987-12-23
Abstract: PURPOSE:To deliver a paper sheet by a single separating mechanism by providing the separating mechanism in common to two or more paper sheet storage parts and preventing a separately resisting means, corresponding to the delivered paper sheet, from rotating when a delivery means and a feed means are rotated in a predetermined direction being based on a selecting instruction of the paper sheet to be separated. CONSTITUTION:Being based on a selecting instruction of a paper sheet to be separated, the paper sheet 3, 4 in either the first or second paper sheet storage part 1, 2 comes into contact with a delivery means 6 in a suitable pressure. Then the delivery means 6 and a feed means 7 rotate in a predetermined direction delivering the selectively instructed paper sheet. Even when the paper sheet is delivered, because a clearance, formed by the feed means 7 and its corresponding separately resisting means, is set so as to enable only the one paper sheet to pass through, the paper sheet is fed sheet by sheet to a conveying path by the feed means 7. The separately resisting means is permitted to rotate not in a feed direction of the paper sheet but in the reverse direction. Thus the paper sheet can be surely fed by a single mechanism.

Title: Photocatalytic hydrophilic member and its production, and photocatalytic hydrophilic coating composition
Inventor: KITAMURA ATSUSHI
IPC: B01J20/06
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain the member capable of maintaining high hydrophilicity on the surface of the member for a long period to prevent the fogging of the member, the formation of water drops, the staining of the member surface, etc., by converting the surface layer of the member into a hydrophilic surface in response to the photoexcitation of photocatalytic titanium oxide contained in the surface layer of the substrate. SOLUTION: This photocatalytic hydrophilic member is produced by forming a surface layer comprising photocatalytic titanium oxide and molybdenum oxide on the surface of a substrate, or forming a photocatalytic titanium oxide-containing layer on a substrate and subsequently forming a surface layer comprising molybdenum oxide on the formed layer. A highly hydrophilic state is a state exhibiting a water-wetting degree of <=10 deg. converted into a contact angle with water, and even wen moisture or steam in air is dewed, the condensed water does form individual water drops in the highly hydrophilic state to produce an uniform water film, thereby not producing a clouding phenomenon caused by the scattering of light on the surface. The photocatalytic oxide comprises an oxide, such as titanium oxide, capable of forming conductive electrons and electron holes by the irradiation of light (photoexcitation) having a larger energy than an energy gap between the conductive electron zone and the valence electron zone of the oxide crystal.

Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric acceleration sensor requiring no expensive structure by coupling a bearing body mechanically with a substrate such that the main sensitive axis of a bending element is included in the surface of the substrate. SOLUTION: When a bending sensor (bending element) 1 sandwiched by two bearing parts 2a, 2b constituting a bearing body 2 is subjected to acceleration, the bending sensor 1 is bent at the opposite ends thereof. The bearing parts 2a, 2b comprise a beam part 22 and a leg part 22 extending, respectively, along the central surface of the sensor 1 and the leg 22 is coupled mechanically with the substrate 3. The bearing body 2 and the bending sensor 1 are disposed perpendicularly to the surface of the substrate 3 and thereby the main sensitive axis of the bending sensor 1 is included in the surface of the substrate 3. Consequently, the substrate 3 abuts against the end face of the bearing part 2a, 2b through mechanical contact parts where electrical contact is also made.  This structure eliminates the need of any additional joint and the bending sensor 1 is connected directly with a printed wiring board along with the bearing body 2.

Title: Control device for starting and stopping electric motor
Inventor: PIITAA JIEI ANSUWAASU
IPC: H02P1/28
Filed: 1990-11-27
Abstract: PURPOSE: To avoid a rapid change due to a load torque of the rotary speed of a motor by changing the conduction period of a thyristor using a microcomputer and hence increasing or decreasing a motor torque. CONSTITUTION: Thyristors (SCR) 16-18 are triggered, for example, by a microcomputer 21 that is a control circuit for conduction state and power is supplied to a motor 10. In this case, by changing the relative time for triggering the SCR 16-19 successively, the conduction period is changed and hence the torque of the motor 10 is increased or decreased. The increase or decrease in the motor torque is controlled, so that a difference between a load torque and the torque of the motor 10 does not exceed an allowable range and at the same time does not change rapidly. To obtain the torque relationship, the application of power is adjusted and the zero cross of voltage and current being applied to the motor 10 is detected by a zero cross detector 50, thus avoiding a rapid change of the rotary speed of the motor 10 due to the load torque.
