Title: Propeller for propelling ship
Inventor: NOJIRI TAKEO
IPC: B63H1/26
Filed: 1981-09-14
Abstract: PURPOSE:To maintain the efficiency of propulsion by raking either of adjacent propeller blades forward or backward, making a discrimination between mutual angles of rake, and increasing the pitch angle of the backward blade. CONSTITUTION:A propeller 3 is provided with even-number of blades. Out of adjacent individual blades 5 and 6, one blade 5 permits the reference line G1 to be raked forward just by the angle of rake thetaR1 and is provided with the angle of rake thetaP1 and the other blade 6 is spaced at an interval (d) at a contact on the external surface of a boss 4, raked backward just by the angle of rake thetaR2, and is provided with the larger pitch angle thetaP2 than thetaP1. As a result, since the blade 6 is placed in a stream of air accelerated by the blade 5, the propulsive efficiency of the blade 6 is hardly reduced, even if the operating conditions of the propeller and its diameter are varied slightly. Besides, since the axial length of the propeller is not elongated, neither the propeller shaft nor its bearing section needs reinforcement.

Title: Communication terminal equipment
Inventor: SUZUKI OSAMU
IPC: H04M1/26
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To enable a user to automatically set a correct circuit class even when the circuit class is not correctly set by storing a calling signal which a line transmits to a given opposite party device as a new line kind and set changing the circuit class. SOLUTION: When line connection with another party is successful by the circuit class different from the circuit class corresponding to a present set of a circuit class value K (S213: No), an initial set activation flag is set (S214) and a value of the present set of the circuit class value K stored in a user parameter table is rewritten into a value of a variable Kn (S215). Then, the circuit class value K is made coincident with a circuit class of a subscriber's line to which facsimile equipment is actually connected. Thus, when a power is supplied so as to start using a device in purchasing it anew, moving or transferring, the circuit class is automatically correctly set without the user intervened and normal calling/transmitting can be performed later on.

Abstract: PROBLEM TO BE SOLVED: To provide a rectifier circuit which can efficiently rectify an AC voltage. SOLUTION: When a negative secondary voltage is generated across the secondary winding Tb and winding Tc for detection of a transformer 2 and a consuming current flows through the secondary winding Tb, a voltage which is lower than that which occurs in the winding Tc is generated across the terminals of the winding Tb. When the voltage at the base B of a bipolar transistor 4 is lower than that at the emitter E of the transistor 4 by about 0.6 V or more, the transistor 4 is turned on. When the transistor 4 is turned on, an FET 3 is biased in the forward direction and saturated, and a voltage which is nearly equal to a power supply voltage is applied across a load 9. When a positive secondary voltage is generated, on the contrary, the voltage at the base B of the transistor 4 becomes higher than that at the emitter E and the transistor 4 is turned off.  The FET 3 is reversely biased and turned off, and a grounding voltage is applied across the load 9.

Title: Method and apparatus for coating paint containing magnetic particles

Filed: 1985-07-03
Abstract: PURPOSE:To successively coat a thin film having uniform quality onto a base material in the longitudinal and transverse directions thereof by locally generating a region where vertical magnetic fields are concentrated by gate plates and stagnating and holding a paint on the base material in the region where the magnetic fields are locally concentrated. CONSTITUTION:The paint 4 is dropped on the base material 3 on the upper stream side in the traveling direction of the base material 3 while the material 3 is run on the gate plates 200a and 200b in the direction of an arrow 8. The paint 4 is stagnated and held to the state of 110a on the base material 3 in the region M10 of the plate 200b where the vertical magnetic fields are locally concentrated. The paint 4 is uniformly distributed, stagnated and held along the size of the plate 200a in the transverse direction of the material 3. Since the sizes of the plates 200a and 200b in the transverse direction of the material 3 are 200a>200b, the coated film 120a and leaking paint are stagnated and held in the state of 110b when part of the paint leaking in the previous stage M10 part arrives at the region M11 of the next plate 200a where the vertical magnetic fields are locally concentrated. The paint is thus partly transferred and the coated film having the uniform quality is formed in the state of 120b.
