Patent JP-H05242750-A (JP)
Title: Resin moulding
Inventor: TAKIGAWA RIKA
IPC: H01B17/60
Filed: 1992-02-26
Abstract: PURPOSE:To maintain the combining force of a protective membrane even though the product is set in a severe ambiance such as in the open air by forming a paint film whose main component is a modified acrylate resin varnish or the like between a resin molding base material and a preventive layer formed on the surface of the base material. CONSTITUTION:Between a resin molding base material and a protective layer formed on the surface of the resin molding base material, a primer paint film whose main component is a modified acrylate resin varnish or a modified polyolefine resin varnish is formed. For example, such a paint film is applied on the base material 1 for examination made by pouring to mold by a glass fiber reinforced polyester resin, making the dry film thickness 10 to 15mum as the object to form a membrane 2 of a prime coat, and a preventive membrane 3 of an acrylurethane resin to protect the material 1 so as to maintain the weatherproof property is formed at the dry film thickness 20 to 60mum, on the surface of the membrane 2. As a result, even though a pattern removing agent is left on the surface of a resin molding product, the adhering force of the membrane 3 is increased to prevent the deterioration of the adhering force for a long period, and a removal owing to a deformation, an extension, or a contraction of the membrane 3 is prevented, and the combining force of the membrane can be maintained for a long period, even though the product is set in a severe ambiance such as in the open air.

Abstract: PURPOSE: To cause a dynamical neutral shaft line at a gunnel material section to incline toward the inboard and to reinforce the rigidity of the gunnel material, by a method wherein, in a small-sized ship made of fiber reinforced plastic, an inboard edge part of a gunnel material is formed in a longer length than that of an outboard side edge.  
     CONSTITUTION: A section of a gunnel material 14 is formed in U-shape whose lower part is open, and an inboard side edge part 5 is formed in a longer length than that of an outboard side edge part 16. The inboard side edge part 15 of the gunnel material 14 is staged (19), and a core material 20, made of lauan material, is adhered at a part below the staged part 19 and is wrapped with a lining 21, made of FRP, in conjuction with the inboard side edge part 15. The outboard side edge part 16 of the gunnel material 14 is fastened on a ship 11 through a fender beam 24 by a bolt or other means. This constitution causes the improvement of the rigidity of the gunnel material through the inclination of a dynamical neutral shaft line at a section of the gunnel material toward the inboard side as shown in a mark 17.

Filed: 1979-03-30
Abstract: PURPOSE:To prevent invasion and contamination of a semiconductor laser device by dusts by a construction wherein, within a closed space defined by closure members such as a cap, base or the like, a path of beam between a laser element and optical window is formed as the second closed space. CONSTITUTION:A resilient heat insulating material 2 is disposed inside of a metallic cap 3.

Abstract: PURPOSE:To reduce the number of switches and to make assembling and adjustment easy, by providing a capacitor which is charged with electricity and discharges the same through an electromagnet when a main switch for turning an automatic diaphragm lever is turned on and off by the excitation of the electromagnet. CONSTITUTION:In the case of a preview operation, the charge of a capacitor 30 charged when a main switch 27 is turned on, is discharged through contacts 5, 1, and an electromagnet 20 when the switch 27 is turned off, then the electromagnet 20 is excited instantaneously, by which an attraction lever 26 is turned counterclockwise and a set pawl 22 is turned clockwise. An automatic diaphragm lever 15 is then turned counterclockwise to stop down the diaphragm of  a lens to a prescribed value. To release the preview, the user turns the switch 27  off, then switches 14, 21 are held on; therefore, a motor 23 is started via an  AND circuit 31, and a gear 35 and a cam 36 make one turn thus forcing the diaphragm of the lens to be fully opened by the arm 15a of the lever 15. The number of switches is thus reduced and the assembly and adjustment are made easy.

Abstract: PURPOSE:To enable high-speed overwriting by providing a magnetic shielding layer having the axis of easy magnetization within the film plane between a recording layer having the axis of easy magnetization in the direction perpendicular to the film plane and a bias layer. CONSTITUTION:The magnetic shielding layer 3 having the axis of easy magnetization within the film plane is provided between the recording layer 2 and the bias layer 4 of the recording medium which has the recording layer 2 having the axis of easy magnetization in the direction perpendicular to the film plane and the bias layer 4.

Title: Latch signal generator
Inventor: MARUYAMA SHIGERU
IPC: G11C11/417
Filed: 1991-03-06
Abstract: PURPOSE:To eliminate an erroneous operation in a latch circuit due to an irregularity in manufacture. CONSTITUTION:A sense amplifier formed of PMOS transistors 1, 2 and NMOS transistors 3, 4 is activated by a sense amplifier selection signal 103, a differential voltage of input signals 101 and 102 is amplified, and input to a latch circuit 7 through an inverter 6. When a voltage level of a nodal point A becomes a sufficiently low potential, a potential of a nodal point B follows to it to be also lowered. When the potential of the point B is lowered to a predetermined potential, a latch signal 105 is generated from a level sensor 8, and input to the circuit 7. The potential of the point B necessary to generate the signal 105 is so set that the potential of the corresponding point A becomes lower than an operating input potential of the inverter 6, thereby inputting a signal 104 to the circuit 7 after the signal 105 is input to accurately latch it.

IPC: G06F3/046
Filed: 1979-04-04
Abstract: PURPOSE: To detect a cursor position without error by detecting electromotive force induced in the cursor and by performing synchronous detection for a driving current and by operating this output voltage in case that induction phenomenan are used to detect the position of the cursor, namely, the center of the winding.  
     CONSTITUTION: Control circuit 15 controls driving line selector switch 11 to select the x-direction or y-direction driving line. Meanwhile, electromotive force induced in cursor 12 is detected by sense amplifier 14 and is subjected to synchronous detection in 16 for a driving current, and operation circuit 17 calculates the position of cursor 12 in the x or y direction from this output voltage. Data output buffer 18 obtains coordinates of cursor 12 on a basis of the position of the selected driving line and positions x and y of cursor 12 in the driving line. As a result, the position of the cursor can be calculated similarly even around the loop because the loop is not folded, and the cursor position without error can be detected because driving lines can be constituted in the same plane.

IPC: G01F1/84
Filed: 1982-03-15
Abstract: PURPOSE:To eliminate the influence of noises and circuit drifts and to improve stability in a Coriolis flowmeter, by adding the time difference between the rises of the outputs of two time widths and the time difference between the falls thereof for a specified number of periods. CONSTITUTION:When a pipeline 1 is under oscillation while fluid flows therein, AC outputs appear from detectors 61, 62 of an AC output type, and are amplified with amplifiers 71, 72 to the two signals e1, e2 which deviate from each other by a time difference DELTAt. The time difference DELTAt is proportional to a mass flow rate; therefore, if the difference DELTAt is measured accurately, the accurate mass flow rate is obtained. The outputs e1, e2 of said amplifiers are inputs to comparators 81, 82 respectively, which produces the comparator outputs e3, e4 deviating from each other by the difference DELTAt. The time difference between the rises of these comparator outputs e3, e4 and the time difference between the falls thereof are added with a counter 11 for the time of one period or integer times thereof, whereby the influence of noises and circuit drifts is eliminated and the stability is improved.
