Title: Semiconductor device
Inventor: SEKIGUCHI TAKESHI
IPC: H01L33/00
Filed: 1988-05-16
Abstract: PURPOSE:To prevent the electric characteristics from deteriorating while facilitating the substrate alignment by a method wherein through-holes are made in the main surface of an insulating substrate loaded with IC containing photosemiconductor element to insert package penetrating terminal heads into the holes for connection. CONSTITUTION:Through-holes 131 are made in the peripheral parts of a ceramic substrate 13 by laser processing. Penetrating terminals are implanted passing through the bottom surface of a package 11. The heads of the terminals are inserted into the corresponding holes in the substrate 13 to be directly bonded by solder 13 for connecting the circuit on the substrate 13 to respective penetrating terminals 12. Since the array of the terminals 12 passes inside the substrate 13, the space inside the package can be made smaller than that of conventional package. The substrate 13 can be connected directly to the terminals 12 without using any wire or lead to produce no needless inductance. Furthermore, the substrate 13 can be automatically aligned with the terminals 12 simply by inserting the heads of the terminal 12 into the through-holes 131.

Title: Line initializing method for common line signal system
Inventor: OKAMURA NORIKO
IPC: H04M7/06
Filed: 1985-06-03
Abstract: PURPOSE:To reduce and simplify the quantity of information by giving reset necessary/unnecessary indications of individual lines of one line group to one line initializing signal. CONSTITUTION:If a trouble requiring initialization occurs in a switching unit 4, busy lines out of lines included in line groups 6-9 connecting the switching unit 4 and adjacent switching units 1-3 and 5 must not be reset because it is necessary to relieve calls on said lines. The switching unit connected to each line has information indicating whether the line is busy or nor. For example, a part having information indicating whether individual lines of the line group 7 are busy or not, namely, information indicating whether the reset of individual lines is necessary or not is added to the line initializing signal transmitted from the switching unit 4 to the switching unit 2 through a common line 11. Thus, the number of initializing signals is reduced, and the time required for line reset is shortened, and the processor load or the like is reduced.

Abstract: PURPOSE:To suppress surface-wave and bulk-wave mode coupling by forming at least one couple of reed screen type electrodes on a piezoelectric substrate and then by forming periodical groove type lattices right under the reed screen type electrodes. CONSTITUTION:On piezoelectric substrate 21 that permits surface elastic wave 25 to propagate, at least one couple of reed screen type electrodes 23 are formed. However, repetitive period (p) of reed screen type electrodes 23 and wavelength (lambda) of surface elastic wave 25 are so set that p/lambda>0.5. Further, the area right under reed screen type electrodes 23 on the reverse surface of piezoelectric substrate 21 is worked into periodical groove type lattices 24. Consequently, when part of surface elastic wave 25 becomes volume wave 26 and is radiated from the surface of piezoelectric substrate 21 at angle phi1, volume wave 26 is converted into diffracted waves 28-31 depending upon the period of groove 24 in addition to volume wave 27 reflected on the reverse surface at an equal angle. Those diffracted waves 28-31 are incident to the surface of piezoelectric substrate 21 at angles phi2 and phi3 differing from angle phi1, so that no mode coupling with the surface elastic wave will be caused.

Filed: 1986-05-26
Abstract: PURPOSE:To converge and focus a light beam on a scanning surface securely by adjusting finely an image formed on the scanning surface by an anamorphic optical system under the control of a means for storing the surface tilt of a rotary polygon mirror. CONSTITUTION:The light beam 2 from a laser light source 1 passes through a cylindrical lens 4 and is incident on the rotary polygon mirror 5 as a vertical linear image, which is reflected there to scan on a scanning surface 8 as a spot image through the anamorphic optical system consisting of an ftheta lens 6 and a cylindrical lens 7. The surface tilt of the polygon mirror from a surface 5a to surfaces 5b and 5c is unevitable, but the shift of the position is stored previously in a ROM 10 to move finely a lens 4 as shown by C under the control of the ROM 10 through the operation of a moving means 9 which responds to the surface tilt. Thus, the surface tilt and axis movement of the polygon mirror 5 are corrected with high accuracy to converge and focus the light beam on the scanning surface all the time.
