Title: Manufacture of original plate of optical disc
Inventor: MIYAMURA YOSHINORI
IPC: G11B7/26
Filed: 1992-12-25
Abstract: PURPOSE:To make the quality of data good by making the phase difference of adjacent laser lights a half wavelength or a multiple of an odd number when the exposure is carried out simultaneously by the laser light divided into a plurality of lights. CONSTITUTION:The laser light for exposure is divided by a semitransparent mirror 3 into a plurality of lights for data signals of guide grooves and modulation signals having address data of sector marks or the like, etc. The intensity of the light reflected by the mirror 3 is modulated when the light passes a modulator 4, and the advancing direction is changed by the mirror 2. As a result, the light passes through a shifting plate 5 shifting the phase by a half wavelength. The other light is, after passing the mirror 3, reflected by the mirror 2, and penetrates the modulator 4 and then the mirror 3 thereby to be combined with the above light. The combined lights pass almost on the same optical axis and are focused, through a condenser lens 6, to the surface of an original disc 7 arranged in the vicinity of a focal point of the condenser lens 6. At this time, if at least adjacent laser lights show the phase difference of a half wavelength or a multiple of an odd number, signals for guide grooves guiding the data or laser lights of good quality can be obtained when the track pitch is made very small.

Title: Contact strucre for micro relay
Inventor: KOBAYASHI KEIJI
IPC: H01H59/00
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To prevent generation of fusing at the time of closing a contact so as to smoothly open/close the contact by forming uneveness on a surface of the contact. SOLUTION: Under the condition where no voltage is applied to between a fixed electrode 4 and a movable electrode 8, a movable substrate 2 faces a fixed contact 5 at a specified interval and a movable contact 10 is separated from the fixed contact 5. When a voltage is impressed to between the electrodes 4, 8, the substrate 2 is attracted to a fixed substrate 1 so that the contact 10 contacts the contact 5 to close the contact. In this case, since uneveness is formed on the surface of the contact 10, there is a small contact area between the contacts 10, 5 so that no fusion or the like occurs.  Accordingly, since no strong force is not required to separate the contact 10 from the contact 5, the substrate 2 returns to its original position easily with its elastic force and thereby the contact 10 can be released from the contact 5 when the voltage is applied to between the two electrodes 10, 5.

Title: Bidirectional rotation brush apparatus and manufacture of the same
Inventor: YAMAMOTO TOSHIO
IPC: H01R39/24
Filed: 1993-12-24
Abstract: PURPOSE:To prevent generation of arc by forming a brush body in a double-layer structure of high resistance part and low resistance part, forming the contact surface of a commutator to become narrower toward both end portions thereof in the rotor rotating direction and also forming a brush resistance to become smaller toward the center from both end portions of the rotor rotating direction. CONSTITUTION:A high resistance part 32 is formed, in the cross-section of trapezoidal form, to have the portions 32a tapered at both ends in the commutator rotating direction W. In the narrow upper surface side of the high resistance part 32, a low resistance part 30 of the trapezoidal form is integrally formed. Therefore, both end regions 42, 44 in the length (b) formed to have smaller contact area as it goes toward both end portions work as the high resistance regions showing larger contact resistance as it goes toward both end portions and the region 46 in the length (a) forms a low resistance region having a smaller resistance value in combination with the low resistance part 30. Moreover, the areas of high resistance regions 42, 44 are reduced as it goes toward both ends from the low resistance region 46. Therefore, variation of resistance between the low resistance region 46 and high resistance regions 42, 44 becomes smooth and spark discharge due to the change of resistance value is not generated.
