Title: Direct driven type conversion device
Inventor: TAKAHASHI HISAYOSHI
IPC: F16H19/02
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To obtain a large thrust force to a direct driven member and to provide a compact pressing mechanism for the direct driven member by forming a pinch roller having a hollow inside and its outer peripheral surface in a V-like groove, supporting it in an eccentric cylinder so that pressing force exerted to the direct motion member can be adjusted in accordance with a turning angle of the eccentric cylinder. SOLUTION: In stead of a compression spring producing the force to pushing press a direct driven member by pushing a pinch roller 57 in a conventional direct driven type conversion device, elasticity caused by bending deformation of the pinch roller 57 is used so as to apply resiliency. This pinch roller 57 is mounted in an eccentric cylinder 59 through the intermediary of a ball bearing 58 which is therefore displaced by turning the eccentric cylinder 59 in order to provide a pressing force which can hold the direct motion member 56 having a suitable size. Further, the pinch roller 57 has a hollow shaft so that the pinch roller 57 can have a suitable spring constant. With this arrangement, a large thrust force can be obtained to the direct motion member and a pressing mechanism for the direct motion member becomes compact.

Title: Rc oscillator
Inventor: KOBAYASHI YOSHITERU
IPC: H03L5/00
Filed: 1986-09-30
Abstract: PURPOSE:To prevent the deterioration of a distortion rate of an oscillating signal in a stable state, and to improve a response speed at the time of switching a frequency, by providing an oscillation level detecting circuit on a control pulse generating circuit, and increasing the response speed only in case the oscillation level is low. CONSTITUTION:In case the oscillation has stopped as soon as the oscillation frequency is switched it is detected and a peak holding capacitor 26 is discharge instantaneously, and a sample holding circuit 27 is set to a sample state. In this state, immediately an output controlling circuit 37 is operated by raising an oscillation output level, therefore, after the oscillation has stopped, the time for starting the re-oscillation can be shortened. Also, until the oscillation output level reaches a sufficient value, a mixing ratio of an output A7 of an integrator 32 and an outout A5 of the second amplifier 31 is made large, and when the oscillation output level has reached sufficient value its mixing ratio is made small. In this way, the response time at the time of switching a frequency is quickened, and in a stable state, an oscillating signal of a low distortion rate can be obtained.
