Title: Mos reproduction circuit
Inventor: KINOSHITA HIROYUKI
IPC: G11C11/34
Filed: 1984-08-20
Abstract: PURPOSE:To prevent a signal voltage from decreasing, to obtain the stable action of a sense amplifier and to scale down a chip by supplying and controlling a pulse signal to a gate of a barrier transistor of a reproduction circuit. CONSTITUTION:The gate of a charging transistor T11 is connected to a boostrap node N, and to its end a boostrap capacitor CB to which a reproduction pulse phiREF is supplied is connected. At the time of precharge, a pulse phiR is set to a voltage more than VDD+Vth, and the node N is easily charged up to the VDD in a short time. Then the pulse phiR is fixed at the voltage VDD in an active cycle. In this state, a barrier transistor T10 is made in the cut-off state, while a correct initial voltage of a data line DL is held, and an increase in capacity of the data line DL can be prevented; therefore the read voltage is increased. Thus even if the precharge time is short, the initial voltage of the data line will not change, whereby the sense amplifier can act stably and the memory cell can be scaled down.

Title: Optical head
Inventor: KARASAWA TADAO
IPC: G11B7/12
Filed: 1985-08-09
Abstract: PURPOSE:To reduce an optical head in weight and to facilitate an easy positioning job with high accuracy by using the plastic material to one of both members which are fixed after mutual position control and having coarse surface of the plastic member. CONSTITUTION:An optical system has a monolithic structure including a laser diode 1, a collimator lens 2, a polarizing prism 3, a 1/4 wavelength plate 4 and a detecting prism 8. This optical system is unified with a plastic monolithic structure of an optical head main body 10 which supports an actuator 5 and a photodiode 9. Such a plastic monolithic structure can secure the extremely high accuracy as long as the dimensional accuracy of an mold is secured. Furthermore an inner wall surface 10f is partly coarsened to increase the frictional resistance between a flange part 13b and the surface 10f. This facilitates an easy fine adjustment of positioning. As a result, the weight of an optical head is reduced together with increase of the frictional resistance between the butting surfaces. Thus a positioning job is facilitated with high positioning accuracy.

To manufacture the mandrel 3, a peeling base material having the diameter which is the diameter of the parallel part plus 1 mm is finished into the diameter of the parallel part 4 and a screw is cut in the rear end part. It is preferable to prepare the bore diameter of the pressing disk 2 so that the clearance of 0.5-1.5 mm is formed between the hole and the step diameter and to use it as an exclusive pressing disk. The clearance between the hole of the pressing disk and the step diameter is enlarged, the automatic alignment of the tip is preferentially executed and the step diameter is made equal to the diameter of the parallel part 4, thus the back pressure applied to the mandrel 3 is reduced.
