Title: Glass composition for fiber
Inventor: IMAI KATSUHIKO
IPC: C03C3/091
Filed: 1986-06-20
Abstract: PURPOSE:To produce the title glass for fiber having excellent water resistance and a high heat distortion point by controlling the B2O3 content in the glass composition at a low value, and appropriately adjusting the contents of other components to keep the dielectric constant low. CONSTITUTION:The glass for fiber is fundamentally composed, by weight, 70.0-80.0% SiO2, 0-2.0% Al2O3, 15.0-21.5% B2O3, 0-1.0% MgO, 0-2.0% CaO, 0-2.0% Li2O, 0-3.0% Na2O, 0-3.0% K2O, and 2.0-5.0% (Li2O+Na2O+K2 O). the glass composition has a low dielectric constant of <=4.5 at 1MHz frequency at room temp. Since the composition has excellent water resistance and a heat distortion point at which the composition is not deteriorated when the binder is burned, the composition is appropriately used as the glass for long fiber to be used especially for reinforcing a printed circuit board.

Title: Spherical actuator
Inventor: TOYAMA SHIGEKI
IPC: B25J17/00
Filed: 1995-05-18
Abstract: PURPOSE: To provide a small-sized spherical actuator in which the movable range of an output shaft is extended. CONSTITUTION: A substantially circular or substantially circular shell rotor 4 is housed in the cavity part 3 of a casing 1 having a substantially circular window 2. Three stators 5a, 5b, 5c are arrange at equal intervals of angle of 120 deg. along the maximum circle (equator) of the rotor 4 in such a manner that each central axis L of the stators 5a, 5b, 5c passes the center G of the rotor 4 to rotatably support the rotor 4 without making contact with the inner wall surface of the cavity part 3. Thus, the structure for supporting the rotor 4 can be simplified and downsized. The surface area of the rotor occupied by the stators is also minimized to extend the movable range of an output shaft.

Title: Digital-to-analog converter
Inventor: YONEYAMA JIYUICHI
IPC: H03M1/66
Filed: 1981-09-16
Abstract: PURPOSE:To decrease the time for a conversion process for a D/A converter using distribution and transfer of electric charge, by giving a converting process to an input signal after dividing it into several parts. CONSTITUTION:Electric charge distributing circuits 11 and 12 plus an integrator 14 are used in accordance with the divided bit groups in order to give a converting process to a digital input signal of N bits after dividing it into several parts.

CONSTITUTION:A masking oxide film 2 is formed on a p-type Si substrate 1, the film 2 is selectively opened, an arsenic-silica glass is applied and a heat treatment is performed to form an n-type buried layer 3. After that, a part which serves as a base region of a lateral P-N-P transistor is again opened, arsenic is driven in using a resist 5 as a mask by an ion-implantation method and a heat treatment is performed. Thereby, the arsenic concentration in a partial region of the layer 3 becomes higher than that in the other region of the layer 3 and an n<++> buried layer 4 is formed. Then, an N-type epitaxial growth layer 6 is grown thereon. At this time, the layer 3 rises, but the region 4 highly doped with arsenic rises higher than that layer 3. Thereby, the connection of the region 4 with the layer 6 becomes certain and the improvement of the hfe-IC characteristics of the completed lateral P-N-P transistor can be attained.
