Title: Cross-point type dot printer
Inventor: KURIHARA TOSHIO
IPC: B41J2/495
Filed: 1980-05-06
Abstract: PURPOSE:To prevent stain of printing paper caused by side printing by constituting the width of a hammer to be narrower than a pitch of a projected screw formed on the outer-peripheral surface of a cylindrical platen. CONSTITUTION:The projected screw 6a is formed on the outer periphery of the platen 6 and a separating member 6b for preventing a recording medium 33 from contacting with the projected screw is fixed between the respective pitches of the projected screw 6a. The separating member 6b is formed of an elastic material such as rubber and sponge, spring metal or plastic or the like and the outside diameter of the member is slightly larger than that of the projected screw 6a. Since the recording medium 33 is pressed against the projected screw 6a while the separating member 6b is pushed aside by a hammer head 27 having a width narrower than the interval of the projected screw 6a in the axial direction, the separating member can not be pushed aside other than the part thereof pushed directly by the hammer head and thereby unexpected sticking of ink to the recording medium is prevented.

Title: Oil hydraulic circuit of automatic transmission for vehicle
Inventor: USHIJIMA FUMIHIRO
IPC: F16H61/08
Filed: 1987-03-14
Abstract: PURPOSE:To insure the stability of running at above a fixed car speed by giving an oil pressure signal to a shift valve switchcontrolled by a solenoid valve at the fixed car speed and compensating for electrical control by mechanical control. CONSTITUTION:When the number of revolution of output shaft or car speed is above a preset fixed car speed, a governor pressure or a pressure which corresponds to the number of revolution of output shaft, is given as an oil pressure signal from a governor valve 25 to an inhibition valve 500, with the result that the valve 500 operates, and an oil pressure signal is given from the valve 500 to the third shift valve 401. The so-called second oil pressure signal acts so as to maintain the operating condition of the third shift valve 401 resulting from an oil pressure signal sent from the third solenoid valve 402. Consequently, even if the third solenoid valve 402 is switched due to any electrical disturbance or abnormality, or the oil pressure signal does not act on the third shift valve 401, the shift valve 401 maintains the previous conditions, and the speed change cannot be generated.

Title: Dry etching method
Inventor: OKUDAIRA SADAYUKI
IPC: H01L21/3213
Filed: 1981-04-22
Abstract: PURPOSE: To form desired patterns with the same dimensional accuracy by etching the Si having pural regions of mutually different impurity concns. substantially only by the ions thereby eliminating the difference in the rates of etching for said different regions.  
     CONSTITUTION: The plasma generated by a magnetron is introduced through a waveguide 17 into a quartz tube 18, where a silicon wafer 2 is irradiated by this by utilizing the mirror magnetic field formed by a solenoid 19 and a magnet 20, whereby the wafer is etched. In this case, the plasma of a high density is obtd. with a low gaseous pressure, and as compared to ordinary dry etching, the plasma is of the gaseous pressure lower by about 2W3 digits (about 10 -4  torr) and therefore the number of neutral particles contributing to the etching is extremely small. On the other hand, the density of the plasma is high and therefore the quantity of ions is extremely large and the greater part of the etching is accomplished by ions. If the mutually different Sis are subjected to etchings under the above-mentioned conditions, the differences in the rates of etching owing to the differences in impurity concns. are virtually eliminated, and the uniform etching is accomplished.

Title: Vco circuit
Inventor: JINNO KEIJIROU

Filed: 1983-04-08
Abstract: PURPOSE:To obtain a desired stable oscillation frequency by providing a means for attenuating a high frequency in the loop of a VCO circuit so that the gain of the loop decreases at a resonance point of the high frequency of a resonance circuit and oscillation conditions are not satisfied. CONSTITUTION:A capacitor 135 is connected in parallel to a resistance 132, so the high-frequency gain of the capacitor 135 decreases. Consequently, oscillations at the high-frequency resonance point of an oscillator 140 are weakened to prevent the oscillations at the high-frequency resonance point, and oscillations based upon the fundamental wave of the oscillator as a center are obtained invariably. Therefore, the need to adjust a free-running oscillation frequency is eliminated and abnormal oscillation at the time of power-off operation and variation in source voltage are prevented.
