Title: Semiconductor device
Inventor: TAKESHITA KOJI
IPC: G11C11/413
Filed: 1995-01-27
Abstract: PURPOSE: To generate an optimum internal clock in accordance with the frequency of an external clock. CONSTITUTION: An output from a delay circuit is delayed by a delay time of the delay circuit in regard to an external clock CLK. In the case where the frequency of the external clock CLK is small, the delay circuit has already risen to an 'H' level at the time of a fall of the external clock CLK since the time of a pulse width of the external clock CLK is longer than the delay time, and an enable signal becomes to be at 'H' level and 'L' level at that time. Therefore a timing circuit 21 for a low speed operation becomes 'enable' and generates an internal clock CLK1. In the case where the frequency of the external clock CLK is large, the enable signal becomes to be at 'L' level and 'H' level and a timing circuit 22 for a high speed operation generates an internal clock CLK2.

Inventor: IMAI YASUAKI
IPC: G11B7/09
Filed: 1989-01-23
Abstract: PURPOSE:To increase the uniformize the damping effect of a viscoelastic body and to make the servo system of an optical driver stable by fixing both ends of the viscoelastic body provided to the outer circumference of an elastic member to a moving part and a stationary part, respectively. CONSTITUTION:A metallic rod 1 and a viscoelastic body 2 made of a silicon or a butyl rubber or the like provided around the rod 1 are provided between a holder 3 holding an objective lens and a base 51 being a fixed part while both ends of the rod 1 and the body 2 are fixed. That is, one end of the viscoelastic body 2 is fitted to a damper base 51 by a length l1 and the other end is fitted to a projection of the holder 3 by a length l2. Since both ends of the viscoelastic body 2 are surely fixed, when the holder 3 is displaced in the focus direction or in the tracking direction, since the viscoelastic body 2 is contracted or expanded according to the displacement, a large damping effect is obtained. Since both end faces of the four viscoelastic bodies 2 are equally fixed, the rolling mode due to the difference from the mounting is not caused.

The temperature rise of the ceramic heater 12 itself is detected by employing the detecting resistor A2 and an electric input into the ceramic heater 12 is restricted so that the temperature of the ceramic heater 12 is not increased to a temperature higher than some temperature determined by the flow condition of the fluid to be heated. In this case, if the temperature of the detecting resistor A2, obtaining a temperature near the surface temperature of the ceramic heater 12, is controlled so as to become lower than a set temperature, the upper limit of the discharging hot-water temperature may be restricted even when the flow amount or the like of the hot-water is fluctuated. Accordingly, an abnormal input inputted in the order of 1.1-1.5 times with respect to a specified input may be detected and restricted.
