Title: Sample-and-hold circuit
Inventor: NAKATANI TAKAYUKI
IPC: G11C27/02
Filed: 1990-11-29
Abstract: PURPOSE:To enable a high speed response by separating a hold capacitor from a feedback loop of operational amplifier and operating the operational amplifier as a simple inversion amplifier, in the sample state. CONSTITUTION:Switches S1 and S2 operate for ON/OFF at the same phase, and a switch S3 operates at the phase opposite to the S1, S2. In the case the S1 and S2 are in the ON state and the S3 is in the OFF state, the hold capacitor Ch is separated from the feedback loop of operational amplifier 2 and made to the state simply connected between an output terminal Vout and a common potential point. As the result, the amplifier 2 operates as the simple inversion amplifier, and the output voltage of amplifier 2 is charged to the Ch as it is. On the other hand, in the case the S1 and S2 are in the OFF state and the S3 is in the ON state, the voltage charged to the Ch is outputted from the Vout to maintain the hold state. By this constitution, the high speed response is attained since an integration circuit is not formed by the amplifier 2 at the charging time to the Ch.

Title: Production of optical information recording medium
Inventor: SUENAGA MASASHI
IPC: G11B7/26
Filed: 1988-12-29
Abstract: PURPOSE:To obtain strong adhesion between two substrates and to improve durability and reliability of the medium by forming a adhesion-preventive film by coating on the area for adhesion in at least the inner circumference of the outer circumference of a substrate before the process for forming a recording layer by spin coating. CONSTITUTION:Prior to forming the recording medium by spin coating, the adhesion-preventive film 6 is formed on the outer circumference and inner circumference of the substrate. Namely, the areas where spacers are to be disposed (adhered) are coated with a coating material comprising fluororesin, polyaminde resin, polyisobutylene resin, epoxy resin, polyolefin, etc., to form the adhesion- preventive film 6. As the resin material used for the adhesion-preventive layer 6 repels drops of org. dye solution, the recording layer 2 is not formed on the adhesion-preventive film 6 and spacers can be adhered under ideal conditions. Thereby, adhesion strength of two substrates is enhanced and the reliability and durability of the medium can be improved.

IPC: G01H13/00
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To measure mass flow rate or density in a high accuracy without complicating the structure especially. SOLUTION: The phase difference or time difference between respective output signals from sensors 6a and 6b as a vibration detector is a function of the temperature of a measuring tube 2 and an axial force, and the axial force is a function of the ratio of the resonance frequency of a first vibration mode of the tube 2 to that of a second vibration mode thereof. On the basis of these facts, the phase difference obtained by a phase difference computing part 92 is corrected by the outputs from a frequency ratio computing part 91 and a temperature computing part 93 respectively. Then, a second vibration mode detector (common to a sensor 6a) is provided at a position corresponding to the antinode of the second vibration mode of the tube 2 (or the node of the first vibration mode), thereby improving the detection sensitivity.
