Abstract: PROBLEM TO BE SOLVED: To enhance yield by irradiating a laminated disk with UV from both sides and disproportionately and variably controlling the outputs of UV radiated on both the sides in such a way that the warpage of the laminated disk in the radial direction is adjusted in a prescribed range. SOLUTION: Two single-sided optical disks are put in a disk laminator to produce a laminated disk 1 with an uncured UV-curing adhesive held between the two disks and the laminated disk 1 is supported by a disk supporting structure. This 1st laminated disk 1 is irradiated with UV under initial set conditions to cure the UV-curing resin 4 and to stick the two single-sided optical disks to each other. The amount of warpage is measured with an in-line warpage inspecting machine, the inspected data are processed and the intensities of radiations of upper and lower UV radiators 6U and 6D are adjusted and controlled. Subsequent laminated disks 1 are then stuck while carrying out feedback control in accordance with the correlation between the amount of warpage and the intensity of radiation of UV.

Title: Fruits removing circuit
Inventor: FUJINO KENICHI
IPC: H03K5/1252
Filed: 1990-07-27
Abstract: PURPOSE:To enable the removal of a fruits signal without wasting a response signal by inputting a gate signal delayed by two transmitting repetition cycles, a non-delay gate signal and a beacon response signal delayed by one cycle. CONSTITUTION:A bracket pulse detected 1 from a beacon response is delayed with sweep delayers 2 and 3 by two sweeps (transmitting repetition cycle) to generate a first gate signal from a first gate generator 5 while a second gate generator 6 inputs the bracket pulse directly to generate a non-delay second gate signal. When a beacon response is inputted into a fruits removing circuit 7 delayed 4 by one sweep 4, the beacon response is outputted only when it is within time ranges of first and second gate signals inputted from the generators 5 and 6. Thus, a fruits signal is removed while a beacon response signal for query of an own station is outputted completely from a remover 7 thereby enabling the preventing of drops in reading rate, detection rate of a beacon target and a drop in display performance.

Abstract: PURPOSE:To obtain good optical performance even if the zoom lens has a long back focus by specifying the set imaging magnification of a 5th lens group which forms the image obtd. by a combined system from a 1st lens group to a 4th lens group onto an image pickup means. CONSTITUTION:A so-called master focusing system to execute focusing by the rear group of the 5th lens group is adopted and the imaging magnification mf of focusing is confined to ¦mf¦ <0.1 in order to minimize the fluctuation in aberration by focusing.

Further, the 2nd lens group and 3rd lens group moving at the time of variable power are disposed with respectively one set of combined lenses. The large aperture diameter diameter and the good optical performance over the entire variable power range are obtd. in this way and the long back focus as long as >= 2.5 times the focal length at the zooming wide angle end is assured.

Filed: 1992-07-28
Abstract: PURPOSE:To obtain an epoxy resin compsn. which can be highly loaded with a filler without decreasing the Tg of its cured article by compounding a biphenyl epoxy resin, a phenol resin curative, and a reaction product of the resin with the curative.

While high loading of a filler is usually needed to reduce the linear thermal expansion coefficient of an IC sealing material, etc., and viscosity reduction has been attempted by using a biphenyl epoxy resin to enable the high loading, such an attempt has a problem with the decrease in Tg, i.e., the degradation of heat resistance. The above-obtd. compsn. enables the high-loading without lowering the Tg.
