Title: Uhf band fundamental frequency crystal oscillator and its filter
Inventor: IWATA KOICHI
IPC: H03H9/19
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide high-performance and high-reliability crystal oscillator and filter by reducing thermal distortion generated on the interface of a crystal element plate and an electrode, and obtaining satisfactory frequency/temperature characteristics by sufficiently thinning electrode film thickness corresponding to the thickness of an ultra-thin oscillating part, which has been limited conventionally in thinning, in order to secure reliability and due to the filiming limit concerning a UHF fundamental frequency oscillator and the filter. SOLUTION: An ultra-thin oscillating part 13a is provided on the bottom of a recessed part by forming a recessed part 13 at one part of one side or both the sides of an AT-cut crystal element plate 1, and fundamental oscillation higher than 300 MHz is obtained by forming a full electrode 12 on one side of the crystal element plate 1 and forming a partial electrode 11 on the other side. For such a crystal oscillator, gold is used as the film material at least of the overall electrode 12. The relation between a thickness T of the ultra-thin oscillating part 13a and full electrode pressure (t) at the ultra-thin oscillating part 13a is set, so that the oscillation frequency deviation is less than ± 40 ppm at least within the range, -35 deg.C to +80 deg.C.

Title: Solid laser
Inventor: YOKOZAWA TAKESHI
IPC: H01S3/08
Filed: 1994-05-12
Abstract: PURPOSE:To raise the output of a laser beam without changing the length in the optical axis direction of a laser medium. CONSTITUTION:Regarding a solid laser which causes a laser medium 7 to absorb an excited light 12 through the medium of a reflecting mirror 9 coated on one end side of the laser medium 7, and oscillates a laser beam 8 from an output mirror 10 side utilizing the energy of the excited light 12 absorbed, the output mirror 10 is capable of reflecting the excited light 12 wholly. As a result, it becomes possible to raise the output of the laser beam 8 by causing the excited light 12 to go and return through the laser medium 7 once, making the distance for the excited light 12 to pass in the laser medium 7 longer, without changing the length of the laser medium 7 along the optical axis, and absorbing the excited light 12 more.

Title: Semiconductor integrated circuit device
Inventor: MIYAMA MINORU
IPC: H01L21/8222
Filed: 1990-04-13
Abstract: PURPOSE:To prevent the mixing of FM modulation noise into oscillation output by removing the vibration of the charge at a p-type silicon substrate, in the IC comprising an oscillating circuit, a frequency divider circuit, and an dividing ratio changeover signal interface circuit to interface with an external circuit. CONSTITUTION:The input stage circuit 54 of a dividing ratio changeover interface circuit 52 is constituted by providing an NPN transistor 58, and the collector is connected to the input terminal of an inner circuit 55, and is also connected to a high voltage power source line 61 through a resistance 60, and the base is connected to a bias voltage input terminal 62, and is grounded through an emitter resistance 63. Since the dividing ratio changeover signal Sn is supplied to the emitter of the NPN transistor 58, the dividing ration changeover signal Sn never affects the charge of a p-type silicon substrate 64 through an n<+> buried layer 68. That is, it never vibrates the charge of the p-type silicon substrate 64. Therefore, the values of the parasitic capacitance 88 of a voltage control oscillating circuit 50 and the parasitic capacitance 89 of the pad 57 for oscillation output do not change, and the mixing of FM modulation noise into the oscillation output of the voltage control oscillating circuit 50 can be avoided.

Title: Method of cutting roll
Inventor: SAKURADA KAZUYUKI
IPC: B23B5/08
Filed: 1986-04-28
Abstract: PURPOSE:To prevent a roll from being broken during cutting, in the case of cutting a plurality of rolls, by moving a cutter toward the bottom of a caliber from one end of the roll to cut the latter, and then by cutting the roll from the other end toward the caliber bottom. CONSTITUTION:Three cutters are located at positions h1, h2, h3, respectively for three rolls 10 which rotate about axes 12, and cutter holders are rotated clockwise about an axis 52 while they are moved in the direction of the axis 52 under NC control to cut a caliber shape. After the holders are rotated by a predetermined angle to cut the roll up to positions i1, i2, i3, the cutters are rotated counterclockwise from the positions j to the positions i by way of the original positions h1, h2, h3 while the cutters are moved in the direction of the axis 52 to cut a caliber shape. Accordingly, the cutters cut the rolls along the paths h1 i1 h1 j2 i2, h2 i2 h2 j3 i3, h3 i3 h3 j1 i1, and therefore, the end of the rolling cutting process does not coincide with one end of roll and therefore, it is possible to prevent the rolls from being broken.

Abstract: 1358128 Self levelling headlamp systems DAIMLER-BENZ AG 22 Sept 1972 [2 Oct 1971] 44036/72 Addition to 1333509 Heading F4R In a pneumatically operated self-levelling system for vehicle headlamps, as described in Specification 1,333,509 further elements are introduced to improve system reaction to acceleration and braking. The system includes in addition to a pressure modulator 1, adjusting motors 11, 20 and a control switch 17 of Specification 1,333,509 a valve 41 inserted into a pipeline 21 between the control switch 17 and the adjusting motor 20 to by-pass the damping effect 40 previously introduced into the pipe-line to suppress fluctuations in the vacuum. This damping effect causes undesirable inertia in the system during acceleration and braking, and the valve 41 removes this. The valve may be electrically operated via a sprung pendulum switch 50, the pendulum 48 making contact with contacts 46 during harsh braking or accelerating, so operating the valve. In an alternative embodiment, the valve may be operated by a mercury switch on acceleration and by the brake light switch on braking.

IPC: H05K3/46
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To prepare a multilayered printed wiring board excellent in through- hole reliability by a dry system manufacturing method. SOLUTION: A both-side metal foil clad laminated plate is obtained by forming a projection of a truncated cone for a through-hole in one surface of a metallic plate, forming a resin insulating layer somewhat thinner than the projection on the projected side, placing a metal foil thereon, and laminating it under heating and pressure. A both-sided metal foil clad multilayered plate is obtained by using the both-sided metal foil clad laminated plate, subjecting the laminated plate to a circuit formation and surface chemical treatment, and laminating it with a metal plate having a one-side projection of a truncated cone in place of a through-hole as an outer layer. The obtained both-side metal foil clad multilayered plate is used as the multilayered printed wiring board.  Since the projection of a truncated cone shape made in one side of the metal plate is used as the through-hole, there can be manufactured a multilayered printed wiring board excellent in through-hole reliability.
