Title: Rotor of axial fan
Inventor: SEKI KATSUYUKI
IPC: H02K21/14
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To simplify the management of the parts and to improve the reliability on the binding strength with a rotor shaft with the restriction on length in the axial direction by forming a rotor holding member with a material which is a magnetic member and superior in the mechanical strength, such as an iron-sintered member or the like, and integrating the same with a back york. SOLUTION: A holding member 5-4 forming a rotor is a magnetic member, and integrated with a back york 5-2. The short stroke is required in the connection holding part of the holding member 5-4 and the rotor shft 4 in consideration of the necessity of the flatness and the restriction on length in the axial direction. The holding member 5-4 is formed by, for example, an iron-sintered bdy, and integrated with the back york 5-2 to ensure the binding strength with the rotor shaft 4, and the reliability on the screwing strength is kept by binding the holding member 5-4 and an arm holding member 3 integrated with a blade by a screw member 9. Further, a low cylindrical part 5-5 as a contact face with a barrel of a rotatably pivotted bearing, is integrally formed on a peripheral edge of the engagement hole with the rotor shaft 4 of a cup-shaped holding member 5-4 acting also as the back york.

Abstract: PROBLEM TO BE SOLVED: To make wire tapping impossible or difficult by making a sending end compress and send a voice signal and making a receiving end expand and restore it between a master unit and a slave unit which mutually communicate voice by radio by means which are respectively provided and temporarily compress and expand in a prescribed periodical timing. SOLUTION: In a master unit 1 and a slave unit 2, microprocessors 12 and 22 control voice signal compressing and expanding devices 13 and 23, compression/expansion timing holding devices 14 and 24 and radio devices 15 and 25, and a voice signal is sent and received in radio waves 3. A sending end between the units 1 and 2 uses compression/expansion timing signals that are produced by the devices 14 and 24, temporarily compresses a voice signal by the devices 13 and 23 and sends it by the waves 3. A receiving end between the units 1 and 2 expands the voice signal which is received by the waves 3 by using the same timing signal and is temporarily compressed with the devices 13 and 23 and restores it the original voice signal. Thus, it becomes impossible or difficult to restore a voice signal from the waves 3.

Title: Detecting mechanism for matching of original point of encoder
Inventor: UDAGAWA SHIGERU
IPC: G05D3/12
Filed: 1983-03-07
Abstract: PURPOSE:To detect the position of a robot arm with a simple constitution by generating a detecting signal just in one time only when the specific teeth have an agreement between two gears at the inside of a motor and also within a working range of the robot arm. CONSTITUTION:A shaft 5 revolves as a motor 1 revolves, and therefore a gear 7 revolves. Then a gear 8 also revolves. The difference of one tooth exists between gears 7 and 8, and the teeth of gears 8 and 9 which engage with each other at first gear again into each other after N revolutions. While the working range of an arm 3 of a robot is set at >=1 revolution, and therefore the shaft 5 has >=N revolutions. Therefore the revolution of the gear 7 is set at >=N revolutions, and the light of a photocoupler 10 transmits just once through holes 9a and 9'a with matching obtained between these holes. Then the number of pulses generated from an encoder is counted with a time point when the light transmits defined as a detecting signal. In such a way, the position of the arm 3 can be detected.

Filed: 1978-04-03
Abstract: PURPOSE: To make glass seal possible at a low temperature by coating a copper oxide film with borax including water of 4 to 5 mol.  
     CONSTITUTION: The circumference of iron-Ni alloyed core metal 6 is covered with copper 7, and copper oxide film 8 is formed on the surface of copper, and further, Na 2 B 4 O 7 .5H 2 O, Na 2 B 4 O 7 .4H 2 O or their miscture layer 9 is laminated with water of 4 to 5 mols on the surface. Then, a melting point is lowered by approximately 490  to 680°C in comparison with anhydrous borax sand. Though the melting point is  further lowered in case of water over 5 mols, air-cells are generated in a glass seal  part, and airtightness is damaged to deteriorate the characteristic of semiconductor  elements. Otherwise, in case of water below 4 mols, the melting point rises, and a  temperature rises at a glass seal time to deteriorate the characteristic of elements.

IPC: F04D29/22
Filed: 1982-03-10
Abstract: PURPOSE:To improve the efficiency of a pump by opening one vane outlet and the other vane outlet alternatively circumferentially of an impeller without varying the sectional area of flow. CONSTITUTION:Vane outlets 4..., 5... for discharging one intake water and the other intake water are opened alternatively in the outer peripheral direction of an impeller 1. Thus, since the discharge water is discahrged in the order along the rotational direction of the impeller 1, the left side discharge water does not interfere with the right one and shear flow caused by one side discharge water and the other side one is not produced. Also, the variation in the flow area from vane inlets to the vane outlets can be reduced to improve the efficiency of a pump.

Title: Mortar filling type reinforcement joint sleeve
Inventor: EBINE KOICHI
IPC: E04C5/20
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To improve the performance by setting the thickness in the central part of a joint sleeve larger than the thickness in both side parts, and specifying the dimensional ratio of length to thickness. SOLUTION: A joint sleeve 10 is formed of a central part 11 having a length corresponding to 1/8-1/4 of the whole length, and both side parts 12, the outer diameter of the central part 11 is constant, and the thickness is determined to a magnitude of ensuring the tensile strength according to the diameter of the central part 11. Both the side parts 12 have the same outer diameter, and the thickness is set to 1/3-3/5 of the thickness of the central part 11. In the application of the joint sleeve 10 to a PC column, when the thickness of overburden of reinforcement is the same as in the past, the axial center of the joint sleeve 10 gets closer to the side surface of the PC column than in the past since the outer diameter in the position where the reinforcement is laid of the joint sleeve 10 is smaller than in the past.  Therefore, the thickness of overburden of the main bar passing the central axis of the joint sleeve 10 is smaller than in the past, and the performance of the PC column is improved. Thus, the arrangement of main bars can be improved without reducing the joint strength.
