Title: Differential gear
Inventor: HIROTA ISAO
IPC: F16H48/295
Filed: 1991-04-10
Abstract: PURPOSE:To widen the selection range of a torque distribution rate, in a differential gear for a vehicle, by contriving the device in such a way that a cam member that is engaged with the pinion carrier of a planetary-gear-type differential mechanism in the rotating direction receives a differential torque to connect a main clutch. CONSTITUTION:When a pilot clutch 87 is connected, a differential torque of a differential mechanism 39 is exerted on a cam 95, and right and left cam thrust forces 111, 113 are caused. By the left thrust force 111, pinion carriers 53, 55 are moved to the left, and the main clutch 61 is pressed between the carrier 53 and a differential gear case 21 so as to be connected. The right thrust force is inputted into the differential gear case 21 via a bearing 99 and a washer 101, and is offset by the left thrust force 111. In this constitution, the pressing force against the main clutch 61 is changed by changing the cam angle of the cam 95, so that a different differential restricting characteristic can be selected.

Title: Ink jet recording apparatus
Inventor: MIZOGUCHI TOMOHISA
IPC: B41J2/01
Filed: 1982-05-10
Abstract: PURPOSE:To make it possible to carry out diagnosis in good preciseness by a simple circuit, by a method wherein the diagnostic signal of an intermittent alternating wave form is recorded in place of an image signal and the state of an ink jet head is judged from the shape of the obtained diagnostic recorded pattern. CONSTITUTION:In place of an image signal, the diagnostic signal of an intermittent alternating wave form with amplitude of 0-220V and frequency of 2- 32kHz is inputted and a diagnostic recording pattern is recorded by recording paper 34. In the diagnosis of an ink jet head, an ink emission impossible state can be directly judged because the pattern is not satisfactorily recorded and, because the delay of response is generated in the ink jet head having air bubbles present therein, an emission starting point does not come to a straight line while an emission finishing point does not come to a straight line when a trailing phenomenon is generated. For example, it is understood that the delay of emission response is generated with respect to a signal with frequency of 10kHz and voltage of 60V and 80V in a part (a) while the trailing phenomenon is generated with respect to a signal with frequency of 20kHz and voltage of 180V in a part (b). By this method, the state of the head can be diagnosed in good preciseness.

Abstract: PURPOSE:To obtain tea of Gynostemma pentaphyllum Makino, having better quality and flavor than those of the conventional products, causing relatively little decomposition of active constituents, and useful as a health drink and decoction, by roasting dried Gynostemma pentaphyllum Makino. CONSTITUTION:Gynostemma pentaphyllum Makino is forced to dry preferably at 30-70 deg.C, and the above-mentioned dried material is roasted preferably at 100- 170 deg.C to give the aimed tea of Gynostemma pentaphyllum Makino. Products obtained by the conventional drying have disadvantages in quality and flavor as follows; strong bitterness, grassy smell and easy growth of molds. The roasting of the dried Gynostemma pentaphyllum Makino has been lately found to give the aimed tea, having strong sweetness, little bitterness and good fragrance, and very suitable for a drink and aqueous solution. The tea has advantages as follows; Active constituents are sufficiently contained, and molds scarcely grow. Deterioration in quality is not caused even by preservation, etc.

Filed: 1990-03-28
Abstract: PURPOSE:To attain equalization without deterioration in the effect even when a complex number impulse response of one line is fluctuated with time by estimating the fluctuation with time of the complex number impulse response at an optional point of time of the line. CONSTITUTION:Sinusoidal wave generators 60-6(N-1) generate prescribed raw waves by using sinusoidal wave coefficients 50-5(N-1) obtained by a coefficient calculator 4 and added by an adder 7 to obtain an estimate value 8. The estimate value 8 is outputted to an equalizer 9 and the equalizer 9 uses the information to equalize a reception signal 1 and a demodulation signal 10 is outputted. Since the estimate value of the complex number impulse response is obtained at an optional point of time, the reception signal 1 is equalized at the equalizer 9 by using it. Thus, even when the complex number impulse response of the line is fluctuated with time, the effect of equalization is not deteriorated.
