Title: High density printing system of dot impact type printer
Inventor: YOSHIKAWA SHIGERU
IPC: B41J2/265
Filed: 1984-09-04
Abstract: PURPOSE:To make it possible to perform high quality and high density printing in low cost, by making the wire guide at the leading end of a printing head movable by the 1/2 quantity of a wire pitch with respect to a dot or dot line. CONSTITUTION:When a printing head 1 performs printing operation in such a state that an armature 4 is attracted to a magnet coil 3, the printing corre sponding to the pitch of the wire needle 5 in an L-side, that is, the impact of an O-mark is enabled.

Filed: 1988-07-25
Abstract: PURPOSE:To contrive elimination of a drive wheel acceleration slip by stretching a set spring between a control rod driven by a drive wheel acceleration slip signal and a housing connected to an acceleration pedal. CONSTITUTION:A control rod 7 is arranged in a housing 6 connected to an acceleration pedal 4 so as to be slided toward the counter arrow mark A direction by a drive wheel acceleration slip signal.

Title: Suspension for vehicle
Inventor: WATANABE KENICHI
IPC: B60G17/015
Filed: 1986-08-05
Abstract: PURPOSE:To improve the rolling and pitching characteristics, by controlling the supporting force of a supporting mechanism arranged between a body and a wheel in the direction for suppressing the variation of relative displacement between upper and lower positions of a spring on the basis of said relative displacement when the vibration frequency is lower than a setting frequency at a point close to a resonant point above the spring. CONSTITUTION:A sensor 23L detects the hydraulic pressure in a hydraulic chamber 74L and a sensor 25L detects the relative displacement between a body and a wheel. On the basis of said detected values, a controller 21 calculates the supporting force being produced from a cylinder device 7L and controls said supporting force. When the distance between the body and the wheel is decreasing, the pressure of the cylinder device 7L is controlled to be reduced. Consequently, the characteristic in an area having lower vibration frequency than that at a point close to a resonant point above the spring can be made different from the characteristic in an area having higher vibration frequency. Consequently, the rolling characteristic, the pitching characteristic and the comfortability can be improved over the entire frequency area.

Filed: 1992-06-19
Abstract: PURPOSE:To supply stable driving power by performing a drive machine transfer while maintaining a 100% load without stopping operation, when the drive machine is switched between a gas engine and an electric motor during operation of a turbomachine. CONSTITUTION:A gas engine 1 is started by a schedule timer, and after performed idling, an engine speed in no-load operation is increased to a predetermined rotational speed higher than an electric motor rotational speed.

Here when assumed, for instance, 50% for load distribution ratios of the engine 1 and the electric motor 3, this engine speed is attained by setting the speed after idling to 1820rpm. Thus with no load fluctuation at all at switching time, stable driving power can be supplied.
