Title: Control device for exercise-loading device
Inventor: TAKAYA MASAMI
IPC: A61B5/22
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a control device for an exercise-loading device, for determining a desired load optimum for the physical body with no application of any appreciably high load to the physical body during every physical exercise, and for controlling the load to the exercise-loading device in order to apply the desired load to the physical body. SOLUTION: When a break point F of increase in a labor strength value calculated by a labor strength calculating means 82 occurs as the load applied to a physical body is increased by an initial load increasing means 84 during an initial stage of an exercise period, a desired labor strength value determining means 86 determines a desired labor strength value PRPM based on the break point F. Further, an exercise-load adjusting means 90 stops increasing of the load by the initial load increasing means 84, and a load of an ergometor is adjusted as if an actual labor strength value PRP follows the desired labor strength PRPM. Accordingly, an optimum load is determined with no application of any appreciably high load to the physical body during every physical exercise, and the load of an exercise-loading device is controlled so as to apply its desired load.

Title: Ringing preventing circuit
Inventor: MATSUNAGA HIROSHI
IPC: H04L5/14
Filed: 1984-06-14
Abstract: PURPOSE:To improve the performance of noise immunity by introducing a low resistance to the input side of a reception circuit to adjust the sum of resistance value between the effective resistance of an input clamp diode and the low resistance. CONSTITUTION:The input impedance of a reception circuit Q2 is substituted equivalently by a series circuit comprising a high resistor R and a diode D1 and an input clamp diode D2. Thus, since the input impedance when the input to the circuit Q2 is a negative potential is expressed by the diode D2, the low resistance R0 is inserted to the input side to adjust the sum of resistance value between the effective resistance of the diode D2 and the low resistor R0, causing a reflection signal to be reflected into the final stable state. Since the reflection signal is produced respectively once at the reception and transmission side and converged, a reception input voltage is not larger temporarily from the final stable state and the performance of noise immunity is improved.

Title: Composite piezoelectric oscillator
Inventor: HIGASHICHI SEIJI
IPC: H03H9/58
Filed: 1977-10-14
Abstract: PURPOSE:To enhance the frequency-temperature characteriatics especially in the high temperaure range by connecting more than one units of the piezoelectric oscillator in parallel. CONSTITUTION:Oscillator 11 featuring zero temperature coefficient (Tp)Tp1 and oscullator 12 featuring Tp2 are connected in parallel at the low- and high- temperature sides. Equivalent circuit 13 is compounded at the oscillation time of equivalent circuit 10, where Re is the effective loss resistance component and Xe is the reactance component respectively. The current  flowing to the oscillator at the high-temperature region is reduced, so such temperature characteristics has just to be obtained that Re may increase gradually at the region of over Tp2 temperature. This can be attained by obtaining R1<R2 between R2 of high-temperature side Tp2 and equivalent resistance R1 of the oscillator at low-temperature side Tp1. As a result, the frequency-temperature characteristics can be enhanced, thus achieving a high-accuracy electronic watch and others.
