Title: Weight sensor
Inventor: OHASHI NOBUYASU
IPC: G01G3/00
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a simple low-cost weight sensor capable of detecting and deciding the accurate weight without influence of heat and the like. SOLUTION: The weight sensor comprises a coiled spring L1 elongating or contracting in response to the weight W of a matter to be measured, an LC resonance circuit having the spring L1 formed as an inductance element, and weight deciding means for deciding the weight W of a matter to be measured based on the resonance frequency of the circuit. When the weight of the matter to be measured is loaded to the spring L1 , the spring L1 is elongated or contracted in response to the weight W, and the inductance of the coil is varied in response to the elongated or contracted amount. As a result, the resonance frequency of the circuit formed with the spring L1 as the inductance element is varied as well, and the weight W of the matter to be measured is decided by the weight deciding means based on the frequency signal responsive to the change.

Filed: 1988-08-12
Abstract: PURPOSE:To complete access to an aimed track in a short time by cutting the direct current component of the output of a speed command means, adding it to an error signal, and forming a means to execute feed forward compensation supplied to a rough actuator means. CONSTITUTION:A speed control system is composed which executes the feed forward compensation to drive a rough actuator 5 with the aid of the position signal of a fine actuator 6 driven by speed anomaly by means of an error detecting means 17 through a filter 42 to cut a speed command value, at least the direct current component, and with the aid of the output added by an adder means 44. Further, at the time of the access, by a two-stage speed control system using the fine actuator 6 and the rough actuator 5, the excessive motion quantity of the rough actuator 6 is suppressed. Consequently, the deterioration of the performance of an optical system due to the excessive movement of an optical spot is reduced, the speed variation is reduced, and the pulling operation to the aimed track can be stably executed. Thus, the access time can be shortened.

Title: Carrier detecting system
Inventor: MINOWA TAKEHIKO
IPC: H04N1/40
Filed: 1984-09-26
Abstract: PURPOSE:To prevent mis-detection of a reception signal due to noise by generating a discrimination signal turned on when the change in the leading of an input signal is larger than the change in noise and turned off when the change in the trailing of the input signal is larger than the change in noise and using the discriminating signal to attain carrier detection. CONSTITUTION:An input signal to an FAX using a line 4 for transmission is inputted to a log amplifier 6, where the signal is amplified logarithmically. When the input signal changing by, e.g., >=10dB is a significant signal, an RS flip-flop 12 is set when a level change higher than the threshold value of 0.24V exists and reset when the level change with lower than the threshold value of 0.24V exists conversely. Thus, the RS flip-flop 12 is set by the leading of the level of >=10dB and reset by the trailing. An output signal CD of the RS flip-flop 12 is transmitted as a status representing that the signal is received by a CPU.
