Patent JP-S604491-A (JP)
Title: Propeller for ship
Inventor: TAKAZAWA ISAO
IPC: B63H1/26
Filed: 1983-06-21
Abstract: PURPOSE:To permit to increase the speed of the ship effectively even in the high speed rotation of the propeller and decrease a slip value to reduce energy loss by a method wherein the propeller blade is provided with a flap-like edge, bent toward the side of a pitch surface, at the trailing edge thereof in the normal rotating direction of the propeller. CONSTITUTION:The propeller blade 2 is provided with the flap-like edge, bent toward the side of the pitch surface, at the trailing edge thereof in the normal rotating direction of the propeller. The form and size of the flap-like edge 3 are determined by the normal rotating number, the kind of the ship or the like, however, the flap-like dege is normally provided with a width of 1/100-1/30 of the propeller radius and a bending angle E of 10-30 deg. with respect to the pitch surface while the surfaces thereof are finished smoothly so as to be continuous with the pitch surface 4 and the back surface 5 of the blade. According to this method, the slip of the propeller is restricted and a crusing speed in the same number of rotation may be increased. The resistance of the propeller is increased by the edge 3 but the crusing capacity may be increased by selecting the form of the aerofoil thereof properly to mitigate the increase of resistance and balance it with the hull and main engine capacity of the ship. The slip value is low, therefore, energy loss may be reduced, the size of propeller may be miniaturized and the thickness of the blade may be reduced.

Title: Image recorder
Inventor: IMAI MASAAKI
IPC: G03B27/32
Filed: 1991-04-16
Abstract: PURPOSE:To reduce a grating-like pattern between the picture elements of a light valve panel and to improve image quality by relatively obliquely and finely moving the light valve panel and a photosensitive recording medium. CONSTITUTION:When 1st three-color exposure is finished, a motor 31 is controlled according to the signal of a panel driving circuit 32 so as to finely move an LCD 7 by as much as the half of a picture element in X and Y directions. Then, the signal is transmitted to a lamp control circuit 26 to make the light quantity of a halogen lamp 2 small and the three-color exposure is started. By performing exposure in a state where the light quantity is made small, an exposing spot is made small. In such a case, a non-exposed part is left in the case of the 1st exposure, but the non-exposed is left little by performing 2nd exposure so that the LCD may be shifted by as much as the half of the picture element in the X and Y directions with smaller light quantity than the 1st exposure again. Thus, the crossed grating-like non-exposed part caused by the structure of the LCD is exposed again and the non-exposed part is reduced, thereby improving the image quality.

Title: Fm receiver
Inventor: WATANABE KAZUO
IPC: H04B1/10
Filed: 1980-08-20
Abstract: PURPOSE:To improve the S/N by lowering the stereo separation degree and the cut- off frequency of LPF provided at the output side of a stereo demodulation circuit, through a noise detection signal based on the strength of received electric field and high band noise component. CONSTITUTION:When the level of an input signal VIFIN of an IF is lowered, a tuning meter driving voltage Vc is decreased and the gain of a 38kHz switching signal supply circuit 22 is reduced, then the stereo separation is lowered. The volage Vc is applied also to a cutoff frequency controlling circuit and the cutoff frequency is lowered by decreasing the 1st and 2nd variable impedances 61, 62. An output proportional to the amplitude of a high band noise signal is obtained by giving an FM detection signal to an HPF1 and a level detector 2. This output is in wired-AND connection to a tuning meter driving lines via an inverting circuit. Thus, when the high band noise signal is increased, the tuning meter driving voltage Vc is lowered with the control voltage inversely proportional to it and the stereo separation and cutoff frequency are lowered.
