Title: Semiconductor memory device
Inventor: IKEDA KYOJI
IPC: G11C11/407
Filed: 1994-08-22
Abstract: PURPOSE: To detect timing with which the output data of the semiconductor memory device is switched. CONSTITUTION: The outputs of plural sense amplifiers 11 are fetched with the DTD 20 and a data transition clock ϕDTD is generated, which falls for a specified period when at least one of these outputs changes. The switching transistor 14 operates in response to the data transition clock ϕDTD to interrupt the outputs of the sense amplifiers 11 and prevent it from being inputted to the output buffer 17 when the output data changes. Consequently, the fluctuations in the power source potential caused by the inversion operation of the output buffer 17 hardly affect the operation of the sense amplifiers.

Title: Semiconductor pellet positioning device
Inventor: YOSHIDA MASAHARU
IPC: H01L21/68
Filed: 1987-08-05
Abstract: PURPOSE:To prevent a position from displacing by providing an opening at the normal part of a position restricting piece to reduce an air to be sucked to the reverse side of the piece through a gap between a semiconductor pellet and the normal part. CONSTITUTION:An opening 11 formed at a position restricting piece 4 is formed by cutting out a position restricting piece 4 along the sides 4a, 4b of a normal part. The length of the opening 11 in the direction along the sides 4a, 4b is longer than a semiconductor pellet 1, and the width of the opening is formed wider than the diameter of the suction hole 3 of a vacuum stage 2. That is, air is taken-in through the opening 11 to a negative pressure part between the suction hole 3 opposite to the opening 11, the rear side of a position regulating piece 4, and a vacuum stage 2. Accordingly, when the piece 4 is returned after the positioning is completed, even if a gap is generated to the pellet 1, air sucked to the rear side of the regulating piece through the gap is reduced to move the pellet 1 to be attracted to the piece 4, thereby eliminating the displacement of the position.

Abstract: PURPOSE:To reduce the number of parts by constituting a recording information signal detecting system and a spot position error signal detecting system out of an optical path splitter, a convergent lens, a double refraction type double image polarizing prism and a photodetector only. CONSTITUTION:Divergent light emitted from a laser diode 5 is turned into parallel light by a collimator lens 4, and is converged on the surface of an optical information medium 1 via a beam splitter 3 by an objective lens 2. Return light reflected from the surface of the optical information recording medium 1 is separated from the forward light again via the objective lens by the beam splitter. Then, the reflected return light obtained from the beam splitter 3 is detected by a photodetector 9 via the optical path splitter 6, the convergent lens 7 and the double refraction type double image polarizing prism 8, which are disposed to coincide with an optical axis of the reflected return light. Thus, since the recording information signal detecting system and the spot position error detecting system are not constituted independently, the number of parts are reduced.
