Title: Ceramic multilayer substrate
Inventor: BANDAI HARUFUMI
IPC: H05K3/46
Filed: 1988-06-09
Abstract: PURPOSE:To have a capacitor of a large capacitance built in without making a signal transmission delay large by providing a plurality of electrodes oppositely facing a low-permittivity ceramic layer on which wiring pattern is formed and laminated high-permittivity ceramic layer. CONSTITUTION:A ceramic multilayer substrate 10 includes two high-permittivity ceramic layers 12 and 14 laminated on each other. Low-permittivity ceramic layers 16 and 18 are laminated on and under these high-permittivity ceramic layers 12 and 14 respectively. Capacitors are formed on a first capacitor electrode 20a and a second capacitor electrode 20b which are in a pair in the top surface of the high-permittivity ceramic layers 12, 14 respectively. A signal is transmitted through a wiring pattern formed on low-permittivity ceramic layers 16, 18. As a result, the capacitance of a capacitor built in becomes large proportionally to the permittivity of a high-permittivity ceramic layer. The transmission delay of a signal with respect to the wiring pattern remains small proportionally to the permittivity of a low-permittivity ceramic layer.

Title: Optical scanner
Inventor: KUNO TORU
IPC: B41J2/44
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To improve accuracy in detecting the position of a beam waist all over the scanning range. SOLUTION: The width of the aperture of a light beam diaphragm plate is enlarged (108), the numerical aperture of an optical system is increased. Thus, a depth of focus at focusing becomes smaller than that at exposing an image. In this state, a beam diameter R on a surface to be scanned is detected (110), it is decided whether or not the beam diameter R is within a reference range (112). In the case that the beam diameter R is not within the reference range, by moving a collimator lens in a direction parallel to an optical axis thereafter until the beam diameter R reaches within the reference range (114), the focal position of the light beam is adjusted. The focal position is adjusted in a state where the depth of focus is made smaller than that at exposing the image in such a way.
