Patent JP-H0887944-A (JP)
Title: Switchable breaker
Inventor: FURETSUDO MOOREMU
IPC: H01H73/30
Filed: 1995-04-26
Abstract: PURPOSE: To reduce the size of a breaker with a smaller number of components by designing a pusher member in the breaker to convert its rectilinear motion at its driving end into its step motion at its working end in consideration of the snap movement of a movable contact in the breaker from its closed state to open state and vise versa. CONSTITUTION: The manual application of force F to a breaker to switch it over to its off-position turns a locker member 7 counterclockwise to push a pusher member 5 leftward. A ramp 57 at a cam part 54 on the pusher member 5 consequently moves beyond a step 18 in a case 1 to direct the pusher member 5 downward. That movement affects an operation finger 53 on the pusher member 5 to apply force directed downward to a leaf spring 42 and to separate a movable contact 4 from a fixed contact 3. The separation of the movable contact 4 is snap-based owing to the step 18. For switching over the breaker from its off-position to on-position, on the other hand, the rocker member 7 and its pullback arm 73 are turned clockwise. While the rocker member 7 is situated at the off-position, the arm 73 holds a considerable clearance gap between it and a pullback pin 56 on the pusher member 5.  The locker member 7 thus reverts to the off-position with no engagement with the pin 56.

Title: Ic card and its production
Inventor: NEZAKI SHINJI
IPC: B42D15/10
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To provide an IC card which has its both smoothed sides by securing a contact between a specific oversheet and a thin plate where an IC module is embedded and applying an electric field of frequency of a specific range to make only the treated film of the oversheet generate the heat to conduct its fusion. SOLUTION: One of both sides of a film made of the nonpolar polyethylene terephthalate resin or polybutylene terephthalate resin having a <=0.1 dielectric power factor at a frequency of 1 kHz to 1 MHz is irradiated by the ultraviolet rays or undergoes a corona discharge treatment. Thus, an oversheet 1 is obtained. Then a contact is secured between the oversheet 1 and a thin plate where an IC module 2 is embedded, and an electric field of frequency of 1 to 300 MHz is applied to the oversheet 1 to make only the treated film of the oversheet 1 generate the heat to conduct its fusion. Thus, it is possible to easily produce an IC card with its thickness uniformed and both sides smoothed.

Title: Magnetic recording and reproducing device
Inventor: SEGI SHINICHI
IPC: G11B5/027
Filed: 1989-04-21
Abstract: PURPOSE:To always perform optimum recording by adjusting a recording current to an optimum recording current value on the basis of the measured value of the depth of a gap when a magnetic head is abraded and the optimum recording current value changes. CONSTITUTION:A gap depth measurement circuit 10 supplies an AC current to the magnetic head 1 from a signal source 101 through a switch 9 and the current value is measured by an ammeter 102, then the voltage of the end of a coil 1b is measured by a voltmeter 103. A computer 104 performs arithmetic operation to calculate the depth of the gap Gd. On the basis of the measured depth of the gap Gd, a recording current arithmetic operation circuit 11 calculates the optimum recording current value and the recording current which flows in the magnetic head 1 is adjusted to the optimum recording current value by a variable resistor 7. Thus, the recording current value is readjusted to the optimum recording current value at that time even when the depth of the gap Gd of the magnetic head 1 becomes smaller and the optimum recording current value changes.

IPC: H01L21/027
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To provide the positioning mechanism of a material cassette, which suppresses the occurrence of dirt and prevents the occurrence of the distortion of a material. SOLUTION: The material cassette 2 moves upward by a push-up pin 17 and the upper face of the cassette 2 is abutted an upper face regulating board 12. The positioning of the cassette 2 in a height direction and the fixing of the cassette 2 to a stage complete in such a state. At the time of pushing up the cassette 2 by the push-up pin 17, a barrel-type roller 20 rotates with a holder 25 and the side of the cassette 2 and the surface of the roller 20 are prevented from being ground. Thus, the occurrence of dirt owing to friction is prevented.  Since the form of the roller 20 becoming standard is a barrel type, the outer periphery of the roller exists in the place of a radius R from the rotary center (center of shaft 29) of the holder 25 and the curvature radius in the barrel type of the roller 20 is also R, the position of the cassette 2 in a horizontal direction does not change at that time.
