Title: Sticking structure for optical element
Inventor: WATANABE NORIKO
IPC: G02F1/1335
Filed: 1990-04-27
Abstract: PURPOSE:To obtain sticking structure prevented from being warped or peeled and generating an optical loss by sticking a seal member around the peripheral edge parts of a pair of optical elements and sealing a liquid layer into a gap part between both the elements. CONSTITUTION:Ultraviolet curing type adhesive into which spacer is mixed is screen-printed on the peripheral edge part of a liquid crystal display element 2, furthermore a microlens array 1 is mounted to form an adhering part 3 and the liquid crystal layer 4 is sealed into the gap between the element 2 and the lens array 1. Since the adhering part is not formed over the whole surface between the optical elements, the two elements can be prevented from being influenced by stress due to their thermal expansion difference and the generation of warp or peeling can be prevented. Since liquid is selected so that the refractive index of the layer 4 is close to that of the lens array 1 and the element 2, a light loss due to the surface reflection of respective optical elements can be almost removed.

Title: Address buffer circuit for dynamic type semiconductor memory
Inventor: YAMAZAKI HIROYUKI
IPC: H01L21/8242
Filed: 1987-05-08
Abstract: PURPOSE:To reduce useless power consumption by controlling a gate by means of an internal activating signal in an address buffer circuit whose column system comes nonactive at the time of refreshing, and making a column address signal nonactive at the said time. CONSTITUTION:Supplied with a refresh signal REF and the inverse of a trigger signal CY, a NOR circuit 7 outputs an internal column address activating signal CADE at L-level at the time of refreshing. This output goes to one input to a NAND gate 5, and a column address signal from the gate 5 is maintained in a stand-by state at a high level without being activated, hence it is made unable to activate a column decoder. Therefore, at the time of refreshing, the useless power consumption by an unnecessary column decoder can be remarkably reduced.

Title: Signal acquiring device
Inventor: MASAKI TOSHIAKI
IPC: H03K5/00
Filed: 1988-05-09
Abstract: PURPOSE:To remove the influence of noise and to acquire an intermittent signal by providing a signal acquiring device with a delay element for delaying an input signal by a prescribed time and outputting the delayed signal to shift the noise generated at the time of generating an intermittent signal properly from the acquisition timing of the intermittent signal. CONSTITUTION:The delay element 8 delays an input signal only by a prescribed time T1 and outputs the delayed signal so as to supply an intermittent signal to an amplifier 1 with the delay of a time T1. Namely, the intermittent signal to be supplied to the amplifier 1 is delayed by the time T1 from the intermittent signal inputted to the element 8 and the delayed signal is acquired by a signal processing circuit 2 through the amplifier 1. Thereby, the noise generated simultaneously with the generation of an intermittent signal can be properly shifted from the acquisition timing of the intermittent signal by setting up the time T1 to a proper value and the intermittent signal removing the influence of the noise can be acquired. Consequently, the acquired intermittent signal can be prevented from deteriorating its SN ratio or an acquisition device can be prevented generating malfunction.

Abstract: PURPOSE: To make it possible to suppress the generation of bright and dark patterns by superposition of lens sheets by forming the lens units of the lens sheets to specific shapes. CONSTITUTION: The lens sheet is a lens sheet having the lens faces formed with the many lens units in parallel on its one surface and is formed with the ridge lines of the lens units to the rugged shapes having a center line average roughness of 0.2 to 3.2μmRmax.
