Title: Magnetic bubble memory element
Inventor: MAJIMA NIWAJI
IPC: G11C11/14
Filed: 1981-11-27
Abstract: PURPOSE:To improve reliability of a titled element, by providing a means for gradually decreasing the driving force of ''Permalloy '', on a bubble receipt and delivery part of a bubble driving pattern formed by an ion implanting method, and a ''Permalloy '' pattern formed on said pattern. CONSTITUTION:On a bubble driving pattern 7 formed as a minor loop by an ion implanting method on a magnetic thin film 6, a ''Permalloy '' pattern 12 is provided through an inclined space 10 and a resin layer 11. When a bubble is driven in the direction (p), a distance between the ''Permalloy '' pattern 12 and the surface of the bubble driving pattern gradually increases toward a receipt and delivery point A of the bubble. In this way, too strong driving force of ''Permalloy '' drops gradually, and receipt and delivery of the bubble are executed smoothly, by which the reliability is raised.

Inventor: NAKAZAWA TOSHIHIKO
IPC: G03G15/04
Filed: 1985-08-30
Abstract: PURPOSE:To prevent the application of excessive voltage and excessive current to a semiconductor laser and to prevent damage and deterioration of the semiconductor laser, even if an integrating circuit has a sample and hold function, by providing two or more kinds of reference voltages for setting the light output of the semiconductor laser. CONSTITUTION:An integrating circuit integrates the detected light output signals and uses the result for controlling the driving of a semiconductor laser. Two or more kinds of reference voltages for setting the light output of the semiconductor laser are provided. For example, the light output of a laser diode 54 is detected by a photodiode 11 and converted into an electric signal. The signal is amplified in an operation amplifier 13. The result is compared with a reference voltage Vf2 in a differential circuit 3 and the difference is obtained. The differential voltages are integrated in the integrating circuit 4. Then, a voltage, which drives the laser diode 54, is obtained in an output circuit 5. Thus the laser diode 54 emits light. When the driving voltage becomes excessively large, an analog switch 26 is turned ON by a timing control circuit 7, and the reference voltage Vf2 is converted into a low level.

Title: Wiper blade
Inventor: KAMIYA MAKIO
IPC: B60S1/38
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a wiper blade which will not be frozen even under the snowfall condition and can ensure good wiping performance during high speed running. SOLUTION: In a wiper blade 10, a metallic flat plate member 20 where a recessed part 22 is continuously formed in the longitudinal direction is buried inside a resin-made blade main body 12 where a wiping part 16 for wiping a glass surface is integrally formed. Designated rigidity is given to the blade main body 12 by the flat plate member 20, so that the pressure produced when the wiping part 16 comes into contact with the glass surface 14 is equally distributed. Thus, as the blade main body 12 is totally formed by resin and further the flat plate member 20 for distributing pressure is buried inside the blade main body 12, it is possible to prevent freezing due to snowfall or the like.  Furthermore, as the pressure is distributed only by one flat plate member 20, the height of the wiper blade 10 can be set lower as a whole so as to reduce influence of an air flow during high speed running.
